Examining the psychometric properties of the PCL-5 in a black community sample using item response theory

Integrating a trauma recovery center into an urban hospital setting serving multiply marginalized patients in the Southeastern United States

BACKGROUND

Few interpersonal violence survivors receive psychosocial services, and those who are multiply marginalized are among the least likely to receive needed care. Trauma recovery centers (TRCs) aim to reduce health disparities by increasing access to trauma-focused care. This study describes the initial adoption, implementation, and reach of the first TRC in the southeastern USA.

METHODS

Funding was awarded to support the adoption of the Grady TRC within an urban safety net hospital in Atlanta, Georgia, and interdisciplinary collaboration was leveraged to support implementation. The electronic health records of 3,238 adult patients seeking medical care were screened for TRC eligibility to determine the program's reach (2020-2023).

RESULTS

53% (n = 1,712) of patients were eligible for TRC services; of these, 16.8% completed TRC intake assessments (n = 288; 84.4% Black, 58.3% female, 47.1% referred for gunshot wounds). Most TRC patients (68.1%; n = 196) screened positive for probable posttraumatic stress disorder (PTSD); many endorsed severe anxiety (44.8%, n = 129) or depressive (23.6%, n = 68) symptoms. Most reported no/low alcohol and drug use.

CONCLUSIONS

A demonstrable need for trauma-focused services was found among violence-exposed patients seeking public healthcare. Integrating the TRC model into institutions serving multiply marginalized patients may help increase access to trauma-focused care for those who may not otherwise receive it.

Understanding nightmares after traumatic events in Detroit (UNiTED): prospective associations with interpersonal violence and posttraumatic stress disorder symptoms

ABSTRACTBackground: Research suggests trauma-related nightmares (TRNs) during the acute aftermath of trauma may contribute to posttraumatic stress disorder (PTSD). However, it is unknown who is most vulnerable to TRNs, which is critical to identify at-risk patients toward whom early nightmare-focused treatments can be targeted to prevent PTSD.Objective: We tested trauma type (interpersonal violence [e.g. assault] vs non-interpersonal trauma [e.g. motor vehicle collision]) as a risk factor for TRNs in a predominantly low-income, Black, urban sample in Detroit, MI, USA.Method: We recruited patients from the intensive care unit following traumatic injury (N = 88; Mage = 39.53 ± SD 14.31 years, 67.0% male, 67.0% Black, 47.7% annual income ≤ $20,000) and administered surveys at three post trauma timepoints: one week (T1), one month (T2; n = 61), and two months (T3; n = 59). Trauma type was assessed at T1 via electronic medical records. Participants reported the extent to which their dreams' content was similar to the trauma for which they were hospitalized across T1-T3. Participants then completed the PTSD Checklist for DSM-5 at T3.Results: TRNs were more prevalent over time among patients exposed to interpersonal violence (80%) vs non-interpersonal trauma (48.7%, p = .005). Patients hospitalized for interpersonal violence faced greater odds for TRNs across timepoints relative to non-interpersonal trauma patients (Odds Ratio = 4.95, p = .021). TRNs, in turn, prospectively predicted PTSD symptoms such that TRNs at T2 presaged more severe PTSD at T3 (p = .040, ηp2 = .31), above and beyond T1 PTSD status.Conclusions: This prospective study provides first evidence that interpersonal violence exposure is a robust risk factor for TRNs, which prospectively contribute to PTSD symptom development. Early intervention on TRNs after interpersonal violence exposure may decrease PTSD risk. Future studies are encouraged to use ambulatory methods to capture nightmares sooner after they occur.

Examining Rates of Traumatic Events and Posttraumatic Stress Disorder Symptoms Among Autistic Adults

Background

Autistic adults experience high rates of traumatic events and posttraumatic stress disorder (PTSD) symptoms. However, less is known about how autistic adults experience (i.e., by directly experiencing, witnessing, and/or learning about) distinct types of traumatic events (e.g., social, nonsocial traumas). Little research has considered whether the four-factor structure of PTSD symptom domains (e.g., avoidance, intrusions, hypervigilance, negative mood/cognition) can be applied for autistic adults. Lastly, understanding how demographic factors (e.g., gender, race/ethnicity) relate to rates of traumatic events and symptoms among autistic adults is critical for understanding disparities relating to PTSD. Therefore, the current study aims to examine self-reported traumatic events and PTSD symptoms, and identify associations with demographic factors, among autistic adults.

Methods

Participants included 276 autistic adults and a nationally representative sample of 361 nonautistic adults who completed online measures, including the Life Events Checklist for DSM-5, Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), Autism-Spectrum Quotient-Short, and Patient Health Questionnaire-4. Analyses focused on evaluating group differences in traumatic events and symptoms and considered associations with demographic factors.

Results

Autistic adults reported significantly higher rates of directly experiencing, witnessing, and learning about traumatic events than nonautistic adults, including more interpersonal events (e.g., physical assault, sexual assault) and fewer transportation accidents than nonautistic adults. Autistic adults also reported significantly higher levels of all PTSD symptom clusters than nonautistic adults. A confirmatory factor analysis and follow-up invariance analyses of the PCL-5 revealed that the four-factor Diagnostic and Statistical Manual of Mental Health Disorders, Fifth Edition (DSM-5) PTSD symptom subscale structure was equivalent across groups of autistic and nonautistic adults.

Conclusion

Autistic adults experienced more traumatic events and PTSD symptoms overall, particularly more interpersonal traumas and hyperarousal and negative mood/cognition symptoms than nonautistic adults. Future research should examine outcomes of trauma exposure, identify protective factors, and examine efficacy of trauma-focused treatments for autistic individuals, in partnership with autistic adults.

Racial discrimination increases the risk for nonremitting posttraumatic stress disorder symptoms in traumatically injured Black individuals living in the United States

Traumatic, life-threatening events are experienced commonly among the general U.S. population, yet Black individuals in the United States (i.e., Black Americans) exhibit higher prevalence rates of posttraumatic stress disorder (PTSD) and more severe symptoms than other populations. Although empirical research has noted a range of symptom patterns that follow traumatic injury, minimal work has examined the role of racial discrimination in relation to PTSD symptom trajectories. The current study assessed racial discrimination and PTSD symptom trajectories at 6 months postinjury across two separate samples of traumatically injured Black Americans (i.e. emergency department (ED)-discharged and hospitalized). Identified PTSD symptom trajectories largely reflect those previously reported (i.e., ED: nonremitting, moderate, remitting, and resilient; hospitalized: nonremitting, delayed, and resilient), although the resilient trajectory was less represented than expected given past research (ED: 55.8%, n = 62; hospitalized: 46.9%, n = 38). Finally, higher racial discrimination was associated with nonremitting, ED: relative risk ratio (RR) = 1.32, hospitalized: RR = 1.23; moderate, ED: RR = 1.18; and delayed, hospitalized: RR = 1.26, PTSD symptom trajectories. Overall, the current findings not only emphasize the inimical effects of racial discrimination but also demonstrate the unique ways in which race-related negative events can impact PTSD symptom levels and recovery across time.

Neigh G, Jovanovic T, Michopoulos V. HIV Interacts with Posttraumatic Stress Disorder to Impact Fear Psychophysiology in Trauma-Exposed Black Women

Background

The prevalence of posttraumatic stress disorder (PTSD) among people living with HIV (PLWH) is higher than in the general population and can impact health behaviors. The influence of HIV on PTSD psychophysiology requires further investigation due to implications for the treatment of PTSD in PLWH.

Objective

Utilizing fear-potentiated startle (FPS), we aimed to interrogate the influence of PTSD and HIV on fear responses.

Materials and Methods

Women (18-65 years of age) recruited from the Women's Interagency HIV Study in Atlanta, GA (n = 70, 26 without HIV and 44 with HIV), provided informed consent and completed a semistructured interview to assess trauma exposure and PTSD symptom severity. Participants also underwent an FPS paradigm to assess fear acquisition and extinction: Psychophysiological indices that measure how individuals learn new fear and then subsequently attempt to suppress this fear.

Results

Women with PTSD, who did not have HIV, exhibited a greater startle response compared to women without PTSD or HIV during late acquisition to both the danger cue, reinforced conditioned stimulus (CS+, p = 0.013)), and the safety cue, non-reinforced conditioned stimulus (CS-, p = 0.046)), whereas women living with HIV (WLH) and PTSD demonstrated blunted fear responses compared to women with PTSD only. During extinction, WLH comorbid with PTSD exhibited an increased fear response during the extinction period in comparison to all other groups (p = 0.023). Women without PTSD demonstrated a reduction in the fear response during extinction regardless of HIV status.

Conclusion

Our findings indicate that HIV further modifies fear psychophysiology in WLH with comorbid PTSD, highlighting the importance of considering HIV status in conjunction with PTSD treatment.

Indirect effect of negative evaluations of therapy on the association between racial stress and posttraumatic stress disorder symptoms in pregnant Black persons

OBJECTIVE

Black pregnant individuals are at disproportionate risk for posttraumatic stress disorder (PTSD) compared to other groups. A wealth of literature suggests racial stress contributes to this inequity, but cultural and structural mechanisms, such as perceived barriers to mental health treatment, underlying the relationship between racial stress and PTSD symptoms remain understudied. Negative evaluations of psychotherapy and stigma represent potential mechanisms, though no previous studies have examined these associations. To address this gap, we tested an indirect effect of racial stress on PTSD symptoms through perceived barriers to mental health treatment in pregnant Black individuals.

METHOD

Mediation analyses were used to assess an indirect relationship between racial stress and PTSD symptoms through perceived barriers to mental health treatment.

RESULTS

At the bivariate level, racial stress was significantly associated with PTSD symptoms (r = .20, p = .03) and negative evaluations of therapy (r = .22, p = .02), but not with stigma (r = .140, p = .147). Negative evaluations of therapy were also associated with PTSD symptoms (r = .43, p < .001). There was an indirect effect of racial stress on PTSD symptoms through a negative evaluation of therapy, β = .08, SE = 0.04, CI [0.01, 0.18]. More specifically, racial stress was associated with a more negative evaluation of therapy, which was in turn associated with more PTSD symptoms.

CONCLUSIONS

Results highlight the need for accessible and culturally competent mental health care for pregnant Black individuals. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Feasibility and acceptability of a virtual mindfulness intervention for Black adults with PTSD and depression: Randomized controlled trial

Mindfulness-based cognitive therapy (MBCT) offers promise as a group-based intervention to alleviate posttraumatic stress disorder (PTSD) and depression symptoms in traumatized Black adults. Given the high level of barriers that exist for low-income Black adults, virtual delivery of MBCT may be helpful. This pilot randomized controlled trial assessed feasibility and acceptability of an adapted 8-week virtual MBCT group intervention for Black adults screening positive for PTSD and depression. Forty-six participants (89.3% women) recruited from an urban safety net hospital were randomized to MBCT or waitlist control (WLC). Overall feasibility was fair (70%); however, completion rates were higher for WLC than MBCT (90% vs. 54%). Group acceptability was high across quantitative and qualitative measures for study completers. Perceived barriers to psychological treatment were high (>9). While showing potential via improved coping skills and positive health changes, this intervention's success hinges on mitigating engagement barriers for future delivery; additional studies are warranted.

Evaluating the Performance of the Primary Care Posttraumatic Stress Disorder Screen for DSM-5 (PC-PTSD-5) in a Trauma-Exposed, Socioeconomically Vulnerable Patient Population

The properties and utility of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) remain unstudied in community-based populations. This study evaluates the performance of the PC-PTSD-5 to determine whether it can be used as a brief alternative to the PTSD Checklist for DSM-5 (PCL-5) in a large public hospital in the southeastern United States. Participants (N = 422; 92.7% Black; 85.8% female; Mage = 42.0 years, SDage = 13.4 years) completed the PCL-5 and PC-PTSD-5 after recruitment from medical clinic waiting rooms and admission lists. Using chance-corrected test quality indices and item response theory (IRT) analyses, we determined optimal cut-scores for screening and examined item performance. Approximately 45.0% of the sample screened positive for probable DSM-5 PTSD using the PCL-5. The PC-PTSD-5 demonstrated high internal consistency and strong associations with PCL-5 scores (total, r = .79; items, rs = .51-.61). A cut-score of one was optimally sensitive for screening (κ[1] = .96), and a cut-score of four had the highest quality of probable efficiency (κ[.5] = .66) for detecting self-reported DSM-5 PTSD on the PCL-5. IRT analyses indicated Item 1 (nightmares, intrusive memories) provided the most information, and other items may not be incrementally useful for this sample. Findings provide preliminary support for the use of the PC-PTSD-5 as a brief alternative to the PCL-5 among chronically trauma-exposed patients in the public healthcare setting.

Indirect effect of race-related stress on traumatic stress and depression symptoms via subjective social status in a Black community sample

Experiencing racism is linked to lower subjective social status (SSS), defined as one's perception of their position in society. SSS is influenced by power, prestige, and objective socioeconomic status (SES). Previous findings suggest that race-related stress may be related to adverse mental health outcomes through SSS in Black Americans, a population that has been deeply affected by continuing legacies of oppression. The current study examines the indirect association between race-related stress and posttraumatic stress disorder (PTSD) and depression symptoms through SSS in a community sample of largely trauma-exposed Black Americans (N = 173). Hierarchical regression analyses indicated that overall race-related stress significantly predicted lower SSS, higher PTSD symptoms, and higher depression symptoms. Analyses also revealed indirect effects of cultural race-related stress on PTSD and depression symptoms through SSS after controlling for SES. Results suggest that the experience of race-related stress, particularly cultural race-related stress, which involves the degradation and disparagement of one's culture and worldview, is associated with more severe PTSD and depression symptoms potentially due to these experiences decreasing Black Americans' SSS. Findings support the need for systemic intervention strategies to disrupt the cultural oppression of Black Americans and improve the societal value and mental health of this population.

Validating the primary care posttraumatic stress disorder screen for DSM-5 (PC-PTSD-5) in a substance misusing, trauma-exposed, socioeconomically vulnerable population

The co-occurrence of substance use disorder (SUD) and posttraumatic stress disorder (PTSD) is common, and is associated with greater severity of symptoms, poorer treatment prognosis, and increased risk of return to substance use following treatment. Screening for PTSD is not routinely implemented in substance use treatment programs, despite clinical relevance. Identifying screening tools that minimize patient burden and allow for comprehensive treatment in this patient population is critical. The current study examined the utility of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) in identifying probable PTSD in a predominantly Black sample of 81 socioeconomically disadvantaged substance misusing hospital patients. The majority of the sample (75.3 %; n = 61) were found to meet criteria for probable PTSD using a suggested clinical cut score of 33 on the PTSD Checklist for DSM-5 (PCL-5). Diagnostic utility analyses were completed and determined a cut-score of 5 for the PC-PTSD-5 to demonstrate the best performance (SE = 0.62, κ(1) = 0.22; SP =.80, κ(0) = 0.61; EEF = 0.67, κ(0.5) = 0.32) in this sample. Results provide preliminary support for the use of the PC-PTSD-5 as a brief screening tool for probable PTSD in substance misusing patient populations. Routine use of the PC-PTSD-5 during assessment may be beneficial when treatment planning with those undergoing treatment for SUD because comprehensive assessment and treatment will provide a better chance of long-term recovery.

A Psychometric Investigation of Racial Trauma Symptoms Using a Semi-Structured Clinical Interview With a Trauma Checklist (UnRESTS)

The term racial trauma is used to describe the cumulative distressing and traumatizing effects of racism in all of its forms, and it closely resembles the construct of posttraumatic stress disorder (PTSD). This investigation aims to increase our understanding of racial trauma by comparing the characteristics of those with a clinically-relevant diagnosis of racial trauma to those without, based on the findings of a clinical semi-structured interview and symptom checklist for assessing racial trauma, the University of Connecticut Racial Ethnic Stress and Trauma Survey (UnRESTS), administered to a diverse group of adults (N = 97). This paper extends prior work on racial trauma by examining the correlations between racial trauma and validated self-report measures of discriminatory distress, controlling for racialization. We examine the correlation between a clinically-relevant diagnosis of racial trauma and racial/ethnic identity. We also compare racism-related PTSD symptoms in those with and without racial trauma to inform clinical assessment. Finally, we examine the factor structure of racial trauma symptoms using the 24 items from the UnRESTS PTSD symptom checklist and compare these to current DSM-5 models. The structure of racial trauma symptoms differed from the DSM-5 4-factor model, as do other PTSD models in the research literature. Clinical and research implications are discussed.
