Traumatic life events (TLEs) have been associated with multiple psychiatric diagnoses, including anxiety disorders, major depression, PTSD, and psychosis. To advance our understanding of the complex interactions between forms of adversity as they manifest across the lifespan, psychosis, and symptom content, we undertook a mixed-methods investigation of TLEs and psychosis. Our research explored the association between cumulative exposures, type of TLE, and proximity to the traumatic event and psychosis; the association between TLEs and clinical symptomology including specific types of delusions and/or hallucinations; and how qualitative data further inform understanding of complex relationships and patterns of past trauma and symptoms as they unfold over time. There were a total of 97 participants in the quantitative study sample, 51 participants with present state psychosis and 46 non-clinical. There were a total of 34 qualitative study participants, all of whom were experiencing psychosis. The quantitative analysis showed that when comparing persons with psychosis to the non-clinical group, there were no group differences in the overall total score of TLEs. However, there was a significant difference in cumulative TLEs that “Happened,” demonstrating that as the number of TLEs increased, the likelihood of clinical psychosis also increased. We also found a correlation between lifetime cumulative TLEs that “Happened” and PANSS five-factor analysis: positive, excitement, depression, thought disorder, activation, and paranoia scores. The qualitative analysis further built on these finding by providing rich narratives regarding the timing of trauma-related onset, relationships between trauma and both trauma-related and religious–spiritual content, and trauma and hallucinatory modality. Analysis of participant narratives suggests the central role of localized cultural and sociopolitical influences on onset, phenomenology, and coping and contributes to a growing literature calling for strengths-based, client-driven approaches to working with distressing voices and beliefs that centers the exploration of the personal and social meaning of such experiences including links to life narratives. Findings also underscore the clinical importance of trauma assessment and trauma-informed care.
Introduction
Traumatic life events (TLEs) have been associated with multiple psychiatric diagnoses, including anxiety disorders, major depression, PTSD, and psychosis (1–3). In a recent epidemiological study, the World Mental Health Survey Consortium found that over 70% of respondents in the general population endorsed exposure to at least one TLE, while 30.5% endorsed four or more lifetime exposures to TLEs (4). Recent meta-analyses have found that persons with TLE exposure are three times more likely to experience psychosis than persons with no past trauma (2) and that TLEs significantly increase the risk for subclinical psychosis (5).
In addition to research linking trauma to psychosis, multiple studies have examined the associations between traumatic experiences and specific symptom domains, including auditory hallucinations (voices), paranoia and delusions (6, 7), as well as non-auditory hallucinations (8, 9). Links between trauma and auditory hallucinations (and to a lesser extent other psychotic symptoms) have also been investigated in combat and non-combat-related PTSD (10–12), borderline personality disorder (13), and dissociative identity disorder (14). Several studies have also sought to unpack the relationship between past trauma exposure and the content of delusions and hallucinations, consistently finding strong direct and/or indirect links between dominant content, themes, and past experiences of adversity (15–18). Structural and community adversity, including migration and ethnic density, are also significant risk factors for psychosis (19, 20).
In spite of a large body of research linking TLEs to psychosis and specific symptom domains, mechanisms of action and the interrelationships between multiple social and environmental risk factors are still not well understood (17, 21–23). Childhood adversity, as well as broader lifetime trauma, tends to be correlated with additional environmental factors, including prenatal insults [such as alcohol exposure during gestation (24), poverty/structural adversity1, and personal substance use (25)]. Muenzenmaier et al. (26), have described “complex trauma reactions” triggered by cumulative social adversities and TLEs leading to a broad range of presenting psychotic or psychotic-like symptoms, including dissociation, flashbacks, hallucinations, and paranoid ideation. Recent debates have centered on the differences and overlap between dissociative phenomena, including hallucinations, and psychotic symptoms as they manifest across traditional diagnostic boundaries [e.g., Ref. (15, 27, 28)].
While a number of studies have investigated the role of migration, far fewer have addressed the relationship between race, non-migration-related racism, trauma, and psychosis (29) and found that dissociation only fully mediated the relationship between trauma and psychotic experiences for African-American (not Hispanic or Asian) young adults; while another investigation found that rates of adversity were substantially higher among ethnic minority participants with psychosis and that adversity partially mediated the relationship between ethnicity and psychosis (30). A recent set of analyses utilizing the National Survey of American Life found that multiple types of adversity increased psychosis risk in African-Americans, including neighborhood difficulties and lack of quality educational options (31). To our knowledge, no previous qualitative studies have explored the intersections between trauma, psychosis, and symptom content among African-Americans in the US, although historical and ethnographic work has drawn attention to significant disparities in diagnosis, treatment, and social responses [e.g., Ref. (32, 33)].
To advance our understanding of the complex interactions between forms of adversity as they manifest across the lifespan, psychosis, and symptom content, we undertook a mixed-methods investigation of TLEs and psychosis. Coding and analysis of a separate qualitative sample followed initial analyses of a quantitative sample. A majority of participants were African-Americans, and the qualitative analyses explicitly focused on the experiences of African-Americans participants. Our research questions were as follows:
(1) Is there an association between cumulative exposure, type of TLE, proximity to the traumatic event, and psychosis?
(2) Is there an association between TLEs and clinical symptomology including specific types of delusions and/or hallucinations and in what ways are trauma and past adversity reflected in the form and content of participant’s symptoms?
(3) How does qualitative data further inform our understanding of the complex relationships and patterns of past trauma and adversity and symptoms as they unfold over time?
Materials and Methods
This study reports the analyses from a novel mixed-methods investigation into the intercept of TLEs and psychosis. The first set of analyses (n = 97) focuses on quantitative data from a sample of individuals with and without psychotic disorders recruited from a large urban university medical center, private referrals, and community treatment facilities from January 2013 through January 2015 in Chicago, IL, USA. Participants were recruited using flyers and direct communication with clinical staff regarding study information from a convenience sample. Participants in the quantitative arm of the study were administered standardized measures that are described in detail in Section “Measures Used to Assess Psychosis and TLEs in the Quantitative Sample.”
The second set of analyses (n = 34) focuses on a set of individual interviews (n = 10) and group interviews (n = 24; two focus groups) conducted with individuals reporting experiences of psychosis. The majority of these participants were recruited from a public mental health agency, which serves individuals with serious mental illness and significant, established disability also located in Chicago, Illinois during the same time period. Researchers queried participants about the circumstances surrounding the onset of psychosis; their understanding of the causes and origins of their experiences; and the content, development, and phenomenology of positive symptoms, including the characterological qualities of any voices.
Qualitative interviews and focus groups employed broad, open-ended questions regarding the onset of psychosis or voices; psychosocial context preceding onset; and current symptoms, symptom content, and treatment experiences. Formal diagnostic instruments were intentionally avoided to avoid “clinicalizing” the interviews, and so diagnosis was only recorded through self-report. Background information on past trauma was collected with the demographics. Qualitative data were analyzed using a grounded theory approach (34), which involves focused interview sampling, transcription and summary, coding of data, development of conceptual categories, analytic memoing, and summary of emerging constructs.
Participants
There were a total of 97 participants in the quantitative study sample, of whom 51 reported present state psychosis consisting of 35 (36%) persons diagnosed with schizophrenia and 16 (17%) diagnosed with bipolar disorder with psychotic features, per consensus diagnosis. Consensus diagnosis was determined by reviewing all research data and collateral information by the study personnel that included an Attending Physician, Psychologists, and a Mental Health Nurse Practitioner. Inclusion criteria for the study included participants between the ages of 21 and 60. The clinical sample must have met criteria for schizophrenia or bipolar disorder/psychosis. A group of 46 (47%) non-clinical controls, with no history of DSM-IV-TR Axis 1 diagnosis per the SCID, were also recruited. Exclusion criteria for both groups included current substance dependence, seizure disorders, and neurological conditions. All participants, clinical and non-clinical, were reimbursed equally for their time and transportation. Demographic characteristics for the sample (Table 1) and clinical metrics were obtained at the study evaluation.
Table 1. Demographic characteristics of quantitative sample.
There were a total of 34 qualitative study participants, all of whom reported either schizophrenia spectrum diagnosis or bipolar disorder with psychotic features. The majority also reported past or comorbid diagnoses of PTSD, dissociative identity disorder, anxiety disorders, and/or major depression. All participants described current hallucinations and/or delusions during interviews and groups. Demographics are listed in Table 2. The majority of participants were African-Americans (23/34; 68%). All participants signed consent forms and agreed to be audiotaped for research purposes. Interviews and focus groups lasted from 1.5 to 3 h and were led by an interviewer–facilitator with personal experience of psychosis, which was intentionally disclosed as a part of the interview process.

Measures Used to Assess Psychosis and TLEs in the Quantitative Sample
Multiple clinical measures were employed to examine the relationship between TLEs and psychosis. The evaluation of forms of delusions and hallucination was based on the SCID and scored for lifetime exposure as absent (score of “1”), subthreshold (“2”), and threshold or present (“3”). The SCID includes an assessment of forms of delusions (referential, persecutory, grandiose, somatic, religious, guilt, jealous, erotomanic, control, thought insertion, thought withdrawal, and thought broadcasting) and hallucinations (auditory, visual, tactile, gustatory, and olfactory) (35).
The Life Events Checklist consists of 17 items that measure exposure to various TLEs (36). The items consisted of exposure to (1) natural disaster, (2) fire or explosion, (3) transportation accident, (4) serious physical accident, (5) exposure to toxic substance, (6) physical assault, (7) assault with a weapon, (8) sexual assault, (9) other unwanted or uncomfortable sexual experiences, (10) combat or exposure to a war zone, (11) captivity, (12) life-threatening illness or injury, (13) severe human suffering, (14) sudden violent death, (15) sudden unexpected death of someone close, (16) serious injury, and (17) harm or death you caused to someone else or any other very stressful event. For each event, participants were asked to select one or more event by checking all that applied along the following continuum: (a) happened to me, (b) witnessed it, (c) learned about it, (d) not sure, and (e) doesn’t apply.
The PANSS was scored along a continuum of severity between one (asymptomatic) to seven (extreme symptom severity). Analysis was conducted via data reduction strategies guided by prior empirical studies of symptom domains assessed by the PANSS (37). Scores were calculated for five factors: positive symptoms (delusions, grandiosity, suspiciousness/persecution, and unusual thought content), negative symptoms (blunted affect, emotional withdrawal, poor rapport, passive/apathetic social withdrawal, lack of spontaneity and flow of conversation, and active social avoidance), cognitive disorganization (conceptual disorganization, difficulty in abstract thinking, mannerisms and posturing, disorientation, and poor attention), excitement (excitement, hostility, tension, and poor impulse control), and depression (somatic concern, anxiety, guilt feelings, depression, and preoccupation). Second, PANSS items that have been shown to identify related symptom domains in cluster analyses that assess anergia (blunted affect, emotional withdrawal, motor retardation, and disorientation), thought disturbance (conceptual disorganization, hallucinatory behavior, grandiosity, and unusual thought content), activation (excitement, hostility, tension, poor impulse control), paranoia (suspiciousness/persecution, hostility, and uncooperativeness), and prosocial (active social avoidance, passive social withdrawal, emotional withdrawal, suspiciousness\persecution, stereotyped thinking, and hallucinations) were also obtained. Items were pooled in this way based on previous factor analytic findings (38, 39). Coefficient alpha, for interrater reliability, was between 0.83 and 0.87.
Data Analyses
Demographic data were analyzed using chi-square tests and analyses of variance (ANOVA). For ANOVAs that yielded significant results (alpha level <0.05), Newman–Keuls post hoc tests were used to identify significant pairwise group differences. We conducted a binary logistic regression to examine the probability that cumulative TLEs increased the likelihood of psychosis. An independent sample t-test was conducted to compare the association of TLEs and aspects of psychosis. Bivariate spearman correlations were conducted to determine separate associations between TLEs and clinical symptomology with particular attention to forms of delusions and hallucinations between persons with psychosis and the non-clinical group. All quantitative data were analyzed using SPSS software version 24.
For the qualitative component of the project, a priori codes were generated following the associations identified as significant and/or unexplained in the quantitative analyses. For example, we explicitly sought to identify and unpack cumulative associations between diverse traumatic events and broader adversity, a topic that the trauma measure utilized in the quantitative study could not address. We also coded the content of participant’s symptoms, looking for associations between past adversity, trauma, and the themes of voices and/or unusual beliefs. Transcripts were independently coded at different time points to establish reliability.
Results
Quantitative Analyses
Demographic characteristics of the quantitative sample are presented in Table 1. Group comparisons revealed a significant difference in race between diagnostic groups, with a larger proportion of African-American participants in the schizophrenia group relative to both the bipolar/psychosis and non-clinical groups (χ2 = 15.38, df = 6, p < 0.02). In total, just over three quarters (77%) of clinical participants were African-American. We also found a significant difference in age across diagnostic groups, showing that participants with bipolar/psychosis were older than participants with schizophrenia and non-clinical controls (F2,94 = 3.282, p < 0.04). There was no significant sex difference between diagnostic groups or the non-clinical group.
When comparing persons with psychosis (n = 51) to the non-clinical group (n = 46), there were no group differences in the overall total score of TLEs exposure (t95 = 0.43, p = 0.67). However, we did find a significant group difference in the exposure of TLEs that “Happened” to the individual (as opposed to those who “Witnessed” or “Learned” about the event), showing that as lifetime cumulative TLEs exposures that “Happened” to the individual increased, the more likely the individual was to exhibit symptoms of psychosis (t95 = 2.42, p = 0.02). We also examined differences in exposure of TLEs that “Happened” and race and found a significant increase in TLEs that “Happened” in the African-Americans sample (F3,93 = 3.03, p = 0.03) (M = 4.27, SD = 3.19). In addition, we found a significant effect of cumulative TLEs on psychosis (OR = 1.174; p < 0.02). Thus, as the number of TLEs increased by one unit, the likelihood of the presence of psychosis also increased.
Spearman’s correlations between the number of exposures of TLEs that “Happened” to the individual and clinical symptomology as measured by the PANSS are presented in Table 3. We found a positive correlation between lifetime cumulative TLEs that “Happened” to the individual and several, but not all, PANSS symptom domains, showing that as the number of TLE exposures that “Happened” increased, the severity of clinical symptomology increased. There was a positive correlation between the number of TLEs and the following PANSS factor and composite scores: positive (r = 0.241, n = 97, p = 0.02), excitement (r = 0.302, n = 97, p = 0.003), depression (r = 0.310, n = 97, p = 0.002), thought disorder (r = 0.216, n = 97, p = 0.03), activation (r = 0.266, n = 97, p = 0.008), and paranoia (r = 0.224, n = 97, p = 0.03). However, there was no correlation between the number of TLEs and negative, cognitive, anergia, or prosocial symptom domains.
Table 3. Correlations between “Happened” traumatic life events (TLEs) and clinical symptomology.
We also examined the correlations between the number of exposures of TLEs that “Happened” to the individual and hallucinations (Table 4). With the exception of gustatory hallucination, significant positive correlations were found between TLCs exposure that “Happened” to the individual and all hallucination modalities: auditory hallucinations (r = 0.196, n = 97, p = 0.05), commenting hallucinations (r = 0.254, n = 97, p = 0.01), conversing hallucinations (r = 0.255, n = 97, p = 0.012), visual hallucinations (r = 0.257, n = 97, p = 0.011),; tactile hallucinations (r = 0.420, n = 97, p = 0.000), and olfactory hallucinations (r = 0.296, n = 97, p = 0.003).
Table 4. Correlations between “Happened” TLEs and hallucinations.
Correlations between the number of TLEs that “Happened” to the individual and forms of delusions are reported in Table 5. We found positive associations between the number of TLE exposures that “Happened” to the individual and 12 specific forms of delusions, indicating that as the number of TLE exposures that “Happened” increased, the more likely they were to experience specific forms of delusions. However, only associations between the number of TLEs and religious delusions (r = 0.196, n = 97, p = 0.05) and delusions of control (r = 0.196, n = 97, p = 0.05) were statistically significant, with an additional trend in persecutory delusions (r = 0.191, n = 97, p = 0.06). There was no correlation between the number of TLEs that “Happened” and delusions of reference, grandiosity, somatic, guilt, jealous, erotomanic, thought insertion, thought withdrawal, and thought broadcasting.
Table 5. Correlations between “Happened” TLEs and delusions.
Given the highly correlated findings between TLEs in both religious delusions and tactile hallucinations, we conducted an independent sample t-test to explore associations between specific TLEs involving physical and/or sexual assault, unwanted or uncomfortable sexual experiences, and religious delusions and tactile hallucination. Interestingly, we found a positive relationship between tactile hallucinations and physical assault (t95 = 3.95, p = 0.000), sexual assault (t95 = 4.65, p = 0.000), and unwanted or uncomfortable sexual experiences (t95 = 3.18, p = 0.003). We also found a positive association between religious delusions and unwanted or uncomfortable sexual experiences (t95 = 1.98, p = 0.05).
Qualitative Analyses
Interviews and focus groups were transcribed verbatim, and a modified grounded theory approach was used to identify themes related to the intersections of race, trauma, and psychosis. Transcripts were comprehensively coded and recoded after a 3-month interval to establish reliability (kappa > 0.90). Findings revolve around four major thematic umbrellas: (1) developmental relationships between multiple, intersecting adverse experiences; (2) variations in the timing of onset related to trauma; (3) trauma, spirituality, and religious symptom content; and (4) trauma and hallucinatory modalities.
Developmental Relationships between Multiple Adversities
Virtually all participants, and all African-American participants, described some form of trauma and, in the majority of cases, multiple forms of adversity, including structural discrimination and racism that interacted synergistically over the course of childhood, adolescence, and early adulthood. Many participants also reported family members with serious mental illness, poverty, unstable home environments, neglect, verbal and/or physical abuse, and disruption of attachment relationships.
• “The voices that I heard was bad ones for the most part. I came from an abusive background, meaning that my family was abusive physically, emotionally and sexually. I was raped and I just heard all these voices. That’s why the doctors thought initially I had schizophrenia.”
• “I would get very mad at my mother for being gone. For having passed away. My mother put me in the hospital kind of like my dad. He was in the same hospital, too. He had a mental illness. My father was also in jail. He was put into a hospital in the past too. He was a patient there. He had voices. He often talked to himself and I would wonder why is he talking to himself? Who is he talking to? My dad heard voices. I caught him in that, too, many times talking to himself. Sometimes I would go to church and people were talking like they heard voices. Sometimes I would see my father talking about [voices] and ready to beat me up and he got very angry. He would say, ‘Just get out of here. Go on back home.’ He would just get really agitated….”
• “Since I was like 12, 13 years old, I used to talk to myself, caught my voices. I didn’t know what it was then. I assumed it was me, cuz I heard it very early. I came introverted somewhat cuz there’s a lotta violence in the streets. I was more of a homebody. I think, for me being a homebody, that’s when the voices got brought up. I just had to entertain myself with the voices and talking.”
Narratives of gangs, substance use, and drug trafficking were often woven throughout. One participant described learning (as an older teen) that his mother had been drinking heavily while pregnant with him, while others described parents with severe addictions throughout their childhoods, as well as parents incarcerated for drug-related offenses. Still others indicated pressure from siblings or peers to start using drugs, as well as more complicated entanglements of money, gangs, and drug use.
• “The kids I hanging with. They got me on drugs. I think it was a negative factor, negative influence on my life, the kids I was with. Other than that, I probably wouldn’t be doing drugs. Yeah, definitely drugs is a factor in [my diagnosis].”
• “I was just getting angry, depressed, sad. My parents, I heard my mother say—she was drinking. She was drinking when she […] was pregnant with me. I heard my father was on my marijuana. Other than them, my mental illness is from both sides of my family, my father and mother’s side. They both have mental illness. I’m just sure that I get—I see it in my auntie, too, on my mother’s side. I see some mental illness with her and everything. It runs in the family.”
• “My mother, she was a heroin addict. I had a problem with her ‘cause people wanna take advantage of her. That’s where most my problems start. They pissed me off ‘bout my mother. I started stickin’ up, stealin’ to start supplyin’ my mother’s heroin so she wouldn’t have to go out there in the streets. That caused conflict between me and my brother. Me and him got in a fight one time. The second time I shot him in the foot. All that’s to say is that I never had no chance at life—childhood or life.”
Among African-American men, a strong subtheme was bullying and/or verbal abuse (often from male members of the household or male peers) related to perceptions of effeminate behavior. For example, several participants reported having been bullied due to perceived homosexuality. Several participants reported responding to such accusations by engaging in stereotypically masculine behaviors such as joining a gang or drinking, while others, publicly or in private, embraced gender minority identities, with one engaging in same-sex sex work as a teen.
• “I was bullied, too, in high school and grammar school. I was bullied. People messing with me and everything, beating me up. I got jumped on by some gang bangers. Used to pick on me a lot like I don’t know how to defend myself or something. Pick on me and everything. I know how to protect myself, though. I ain’t gonna let too many people try to mess me up. My father said that I was gay. He said, ‘People think you gonna be gay cuz you don’t have many women around. [But] I wasn’t gay…. I’m not gay.’”
The above experiences virtually all unfolded in racially segregated neighborhoods and housing projects with high rates of poverty, gang violence, and limited access to quality job and/or secondary education. About half the participants remained in such neighborhoods and explicitly foregrounded the risks of violence in their communities as a major factor in their experiences of ongoing treatment and recovery. Just 2 weeks before, a focus group held at a Chicago South Side drop-in center, for example, participants noted that, only a few blocks away at a public park, over a dozen community members (including children) had been killed or seriously injured in a day-time drive-by shooting.
Timing of Trauma-Related Onset
In discussing the relationship between traumatic events and the onset of psychosis, most participant accounts fell into one of two categories: childhood onset of voices in the midst of acute traumatic experiences (e.g., sexual abuse) and older adolescent or adult onset following a series of adversities (as well as drug or alcohol use) but that was nevertheless temporally disconnected from any single traumatic event.
The content and characteristics of voices arising during acute traumatic events in childhood were generally much more likely to mirror real-life abusive figure(s). For instance, voices that began during episodes of severe sexual or physical abuse were typically verbally abusive, telling participants that they “deserved what [they] got,” were “whores” or “sluts,” would never amount to anything and/or never succeed.
• “There’s a lot of voices that I hear. All grown men saying the same thing over and over. I’m no good, I’m worthless. Kill yourself. Just repeatedly over and over and over and over by men.”
• “…they keep telling me to kill myself. I’m no good. I’m worthless. To kill myself repeatedly.”
• “A lot of negative remarks, they ain’t gonna amount to being nothing, they gonna grow up to be nothing, you’re a failure, and all that stuff.”
One participant with trauma-onset voices described her voices as “glued to your experience through childhood experience.” In spite of hearing voices from an early age—typically beginning in early to mid-childhood within this subgroup—most participants reported not receiving a diagnosis of (or treatment for) a psychotic disorder until a much later time point. It was generally ambiguous whether these later diagnoses were exclusively tied to voices, or in fact stemmed from the addition of later onset symptoms and/or functional disability.
For those with later onset and multiple forms of adversity and associated risk taking (substance use, drug trafficking, and participation in street gangs, as described above), connections between psychotic symptoms and particular experiences were less clear—e.g., it was far less common for participants to report voice or symptom contact that amplified or re-played a particular event and associated interpersonal exchanges (such as the messages of an abusive figure). Themes consistent with participants’ lives and broad experiences of individual and community adversity and discrimination were nevertheless common, for example, delusions involving gangs or pimps or demonic voices tempting participants to use drugs or engage in illegal activities.
Trauma and Religious–Spiritual Content
The majority of participants described multiple entanglements between religious faith, spiritual beliefs, and their experiences of psychosis and adversity. Examples ranged from distinct voices that reflected demonic forces, or a G-d or Jesus-like messianic figure, ostensible delusions of reference involving messages from G-d or the devil, automatic thoughts related to participants’ addictions, and perceived temptations as attributable to the devil while automatic protective thoughts were attributed to G-d; and the involvement of pastors or other religious figures who helped participants make sense of their experiences and distinguish between those that were divine versus demonic in origin.
• “Well, there are voices from above. I label it as G-d. It’s a noise, but it’s a feeling of ‘I must something.’ It is like a voice of something talking. Sometimes it’s sort of like an amen kind of a noise. Like a church music kind of noise. That kind of noise. There are voices within that.”
• “I think they’re demons. I think that G-d talks to you and I think that demons talk to you. When I was drinking and using drugs, they was always telling me to kill myself. That I wasn’t worthy, that I didn’t amount to nothing. When I gave my life to G-d and turned my life over, the devil still tried to come at me. I would hear his voice, but I also read the bible and I believe in the word of G-d. I had to choose G-d’s word over what the devil was tellin’ me. The bible tells me that the devil is a liar. Whatever he’s tellin’ me that’s negative, he’s tellin’ me to kill myself, that’s not something that G-d would want me to do.”
• “When I go to church and all, they teaches me to tell me why the voices are talking like that. [Interviewer: Your pastor at church does?] Yeah, tells me not to listen to the voices telling me to hurt yourself.”
• “I said that I’ll be listening to the preacher preaching, and he’s telling me which one is—why you shouldn’t listen to the bad side. The bad side try to get you to hurt yourself. He be talking about teaching ’em [voices] how to do good things, too, but he be telling why the bad things be happening, like getting jumped on or getting beat up a lot. They tell you what spirit that is telling you to hurt yourself.”
Trauma was often tied to these experiences in both direct and indirect ways. For example, demonic “temptations” (whether communicated through voices or non-auditory messages) often involved risk behaviors deeply interwoven with neighborhood poverty and a lack of supports and access to child and family services such as drug use, drug trafficking, gang involvement, and survival sex. Positive voices, even when not explicitly religious or spiritual in nature, were not infrequently described as forces or entities, which would protect the participant against adversity or violence or to reassure them of their core morality or humanity in spite of “immoral” activities and events they had been exposed to (or previously participated in).
• “One time I go outside at 2:00 a.m. Somethin’ tells me that somethin’ ain’t right. Like you talkin’ to me like it’s a warning sign. Like you talkin’ to me, that’s the way—that’s how I hear it. Like you talkin’ to me. I changed my mind. I’m not gonna catch the bus. I turned around and went upstairs. Where I live there’s a park across the street. One of the bus stops is right there. About 2-min long up the steps I heard some shootin’. As I look out the window, I saw a body layin’ down and a couple guys runnin’. The very same bus stop I was gonna catch the bus at. That’s why I say it’s a good voice and a bad voice. The voice that I heard, I feel it was comin’ from G-d. If it was an evil voice, I feel that I wouldn’t got that notice.”
Several participants whose narratives involved accusations and/or internalized concerns about sinful behavior and/or stigmatized gender or sexual identit(ies) described various uses of religious faith or spiritual practice to address their concerns or reassure themselves that they were (in fact) good, ethical people.
• “Jesus [described as a voice earlier in the interview] reassures me…that He loves everyone. Regardless of sexual orientation.”
• [Reporting what her voices say]: “I get, ‘That’s not the right thing to do, Carol [pseudonym].’” [Pause] “You can get through this day without thinking about going back and using drugs.”
Trauma and Hallucinatory Modality
While participants most frequently described, and spent the most time discussing, ostensible delusions (particularly paranoia) and auditory hallucinations (“voices”), altered perceptual or somatic experiences in other modalities were common. Participants’ descriptions generally revolved less around literal “hallucinatory” experiences than they did around more existential alterations of experience and/or “felt presences,” which tended to be subtler and harder to describe. In many cases, participants reported that such presences represented ghosts or spirits, generally of deceased loved ones.
• “A smell like, let’s see—maybe it tastes like you wanna drink some water cuz I’m dizzy. Almost like a shocking feeling, but the smell it’s like maybe more like a taste. Maybe it smells like air, like air.” [Q: In some way that’s different from the air that’s already there?] “Right, it’s not the same. It’s different.”
• “I can see my [deceased] aunt and my uncle and you see, I see them. Yeah, I see a lot of people up there when I look up [toward the voices].”
• “I feel like, like it’s a lifting, sort of like a lifting feeling, like of something being lifted.”
• “For me it’s more like a feeling, too. Like something that makes me turn my head. Like something that’s there that I—almost like a buzz or a tone or something.”
A number of participants connected non-auditory–verbal experiences directly to G-d or spirituality. For example:
• “It’s bothersome and there’s noise, but then it’s like this singing like this noise, and I feel like G-d, you know, G-d makes these noises [‘voices’].”
In contrast to the previous themes, direct links between these non-verbal experiences and trauma were unclear, and no participant in this sample explicitly described non-auditory experiences as sexual or violent in nature.
Discussion
The urban experience for African-Americans living in segregated neighborhoods and/or housing projects often involves exposure to high rates of poverty, gang violence, and limited access to quality secondary education and job opportunities (40, 41). Increased exposure to TLEs tends to be more frequent in low SES and racial minorities groups (42, 43). In comparison to Caucasians, African-Americans have reported increased exposure to violent assaults (44, 45) including gun-related violence (46, 47). Although racial disparities in access and outcomes are well documented [e.g., Ref. (48, 49)], relatively little empirical research has focused on the complex relationships between trauma and the subjective experience and phenomenology of psychosis, including symptom content, within specific ethnic/racial/cultural minority communities [for exceptions, see Ref. (33, 50)].
The mixed-methods data reported here replicate existing findings in identifying strong and significant links between cumulative trauma exposure and psychosis that cut across traditional diagnostic boundaries (2, 3, 51, 52). We extend this literature by demonstrating that these findings hold in our predominantly African-American US sample, where the relationship between TLE and psychosis may be particularly relevant due to higher likelihood of TLEs among ethnic minorities. Increased and more nuanced understanding of the role that such environmental factors play in the development of psychotic disorders helps parse the heterogeneous etiology of these illnesses and possibly points toward more personalized treatment conceptualizations.
Beyond demonstrating a general link of greater TLEs and psychosis, we found specific types of psychosis symptoms associated with TLEs, including multiple types of hallucinations, religious delusions, and delusions of control. We further found that tactile hallucinations and religious delusions were significantly correlated with history of unwanted sexual experiences and, for tactile hallucinations, with past physical and sexual assault. We discuss these findings and their implications in the sections that follow.
Our qualitative analyses were designed to further unpack, potentially confirm, and deepen the findings from the quantitative study. The qualitative findings underscore the complex and synergistic relationships between multiple forms of individual trauma (including bullying, harassment, and abuse) as they unfold against a backdrop of racial segregation, poverty, drug trafficking, gang violence, and neighborhood disadvantage. In addition, we report multiple ways in which both individual-level and neighborhood-level themes and dynamics are reflected in the form and content of both voices and unusual beliefs. For example, we found that an array of themes related to participants’ childhood experiences and associated attempts to cope with these experiences were reflected in both the content of voices and subject’s interpretations of their meaning and significance.
Cumulative Exposure, Type, and Proximity to the Traumatic Event and Psychosis
National comorbidity studies and meta-analysis have reported a potentially causal relationship between cumulative TLEs exposure and psychosis (26, 53, 54). Our data are consistent with other studies that show that the overall lifetime TLE exposure is significantly higher in the African-American population (47, 55, 56). In turn, our finding that cumulative TLE exposures that “Happened” to the individual increased relative to reporting psychotic symptoms is consistent with existing research, highlighting the likelihood of multiple exposures amplifying the risk of psychosis beyond individual stressors alone (5, 25, 57). For example, analysis of the United States National Comorbidity Survey (NCS; n = 5,782) and the British Psychiatric Morbidity Survey (BPMS; n = 8,580) found that after adjusting for demographic confounds, substance use, and depression, experiencing two TLEs increased psychosis risk by 3.37 times (NCS) and 4.31 times (BPMS), respectively, compared to 30.16 times (NCS) and 192.97 times (BPMS) for individuals reporting five TLEs (58).
The nature of the relationship between collective trauma and/or socioenvironmental adversity and psychosis indicates that the urban environment may increase the likelihood of exposure to TLE in persons who later develop psychosis (59). Our qualitative findings underscore the synergistic effects of both individual- and neighborhood-level adversity, with both psychological and biological components, including exposure to illicit substances (prenatal and during childhood/adolescence) and chronic background stress. We suggest that future research needs to more explicitly model both biological and (ongoing) psychological mechanisms and associated (adaptive or maladaptive) coping into early adulthood. Participant narratives also suggest that neighborhood adversity, particularly threat of gang-related violence, may be an important maintaining factor for both paranoid beliefs and voices.
TLEs and Participant’s Symptoms in Form and Content
Associations between trauma and delusions have been reported in multiple studies (23, 57, 60). A study conducted by Scott et al. (12), examining the association between trauma and delusions found that persons who endorsed any type of delusion were significantly more likely to have been exposed to a traumatic event and that as the exposure to trauma increased, the relative risk of experiencing delusions increased significantly. Exposure to an urban environment has been shown to increase anxiety, negative belief about others, and jumping to conclusions in persons with persecutory delusions when compared to a non-clinical group (61). Interactions amongst discrimination, deprivation, stress, mistrust, social inequality, and lack of social support were proposed as predictors of both affective and non-affective psychosis (62). Likewise, auditory hallucinations across diagnoses have been strongly linked to childhood adversity, particularly sexual abuse (63, 64).
In line with previous research, we also found multiple direct and/or indirect emotional and thematic links between adversity exposure and the content of voices and delusions, including voices that mimicked the sentiments of abusive figures, and paranoia that reflected community contexts characterized by poverty, gang, police activity, and near constant background threat of violence (15, 16, 18). Rather than finding that voices and delusional beliefs predominantly reflected negative trauma-linked content, many of our participants reported positive and/or protective content, including voices perceived to originate from G-d, Jesus, or protective spirits, findings which are consistent with Jones et al. (65). Our finding that several participants reported voices as a source of comfort and support also highlights the need for sensitivity amongst healthcare workers in not treating hallucinations as unilaterally negative experiences, which need to be eradicated.
TLEs, Psychosis, and Spiritual Experiences
In the existing literature, religious beliefs have been reported as a source of strength, comfort, and encouragement in managing psychiatric difficulties related to traumatic events (66, 67). Religion or spirituality may also provide a framework to understand or bring meaning to the individual who experienced a TLE (68, 69). Religious practices such as prayer or meditation, worship, and participation in religious services can engender hope and increased social support among individuals with serious mental illness (70–72). While not universal, religious/spiritual explanations of psychotic experiences, religious themes, and/or content (such as hearing the voices of G-d), and faith-based coping and healing practices (including explicit discussions regarding the navigation of voices with pastors or preachers) were common. For many participants, positive religious or spiritual beliefs, including those entangled directly in their voices and psychotic experiences, were described as offering advice, guidance, moral reassurance, and/or fortification against temptations or demonic intrusions. For at least some clients, these temptations or intrusions (for example, commands such as “take drugs,” “shoot him,” “have sex,” or delusions involving similar themes) were directly associated with past adversity.
Relationship and Patterns of Past Trauma and Symptoms over Time
The causative evidence of the association between trauma and psychosis is the strongest for the manifestation of hallucinations (73). Experiencing trauma has been shown to increase the likelihood of verbal hallucination fivefold (74). The phenomenological associations between trauma and hallucinations have shown that hallucinations with content related to trauma are not only found in psychosis they may actually shape the themes of the hallucinatory experience (16, 73, 75). In a recent systematic literature review of studies investigating voices, the association between trauma and voices has been explored in multiple realms including phenomenology, causal link, neurobiological hypotheses, and treatment interventions (76). Much of the research emphasis has focused on the associations between trauma and verbal hallucinations with much less emphasis between trauma and other types of hallucinations, including tactile or olfactory (77). Our research examined the association of trauma and all forms of hallucinations. Interestingly, the strongest association was found between TLE’s that “Happened” and tactile hallucinations, although there was a positive correlation between TLE and most types of hallucinations. Our qualitative data further link the association between a specific traumatic event such as sexual assault and the onset of psychosis and draws attention to a potentially traumatogenic subgroup of patients whose voices began in the midst of acute trauma in childhood but were later diagnosed with a psychotic disorder, and a subgroup who, in spite of significant trauma, did not develop psychosis until early adulthood. This finding further supports the clinical need of evaluating current and past trauma throughout the lifespan as symptoms associated with a TLE may occur during or in close time proximity the event or may not manifest until much later in life (78).
There are limitations of this study in that both quantitative and qualitative datasets reported here are cross-sectional and can only establish correlations and perceived causal connections rather than empirical causality. In addition, our sample was predominantly African-Americans living in a particular, notoriously segregated urban environment; our qualitative analyses are meant to deepen our understanding of the interplay of trauma, psychosis, and spirituality within a particular group and associated sociogeographic context, not to generalize. We also had no mechanism for verifying TLE, although it should be noted that retrospective accounts of adversity amongst psychosis populations have consistently been shown to be reliable and valid and are more likely to underreport than overreport TLEs (79–81).
Finally, our findings echo the extant literature in foregrounding the importance of childhood adversity, neighborhood characteristics, and cumulative adversity with response to both the epidemiology of psychosis and the process of recovery and healing. Experiences described by qualitative participants were far from unilaterally negative, and participants consistently linked the content of symptoms to an array of life events and challenges. Taken together, these findings foreground the importance of trauma assessment and conversations aimed at understanding the role that traumatic experiences have played in clients’ lives, in the genesis of their mental health challenges, and in the content of these experiences. From a public health perspective, they add further fuel to calls for both research and preventative interventions aimed at addressing the negative impacts of childhood structural adversity and neighborhood disadvantage.
