Factor structure of posttraumatic stress disorder (PTSD) in persons with serious mental illness.

BACKGROUND: Trauma and posttraumatic stress disorder (PTSD) are common among individuals with serious mental illness (SMI; e.g., schizophrenia, schizoaffective disorder, bipolar disorder, treatment refractory major depressive disorder), with resultant functional impairment. Previous studies have not evaluated the factor structure of the PTSD Checklist (PCL) among persons with SMI. AIMS: This study evaluated the factor structure of the PCL in two large SMI samples from public mental health treatment sectors screened for PTSD using the PCL. METHODS: Four different models of PTSD were tested using confirmatory factor analyses. RESULTS: Results indicated that the DSM-5 4-factor model (intrusion, avoidance, numbing, and hyperarousal) had the best fit. Further, the DSM-5 4-factor model demonstrated measurement invariance. CONCLUSIONS: Results supported the suitability of the DSM-5 4-factor model of PTSD among people with SMI.

Positive PTSD Screening and Its Health Correlates in Patients With HIV in Urban Primary Care Settings.

Posttraumatic stress disorder (PTSD) is underdiagnosed and undertreated in primary care, especially among African American individuals. The current study assessed documentation rates of PTSD and clinical health correlates among 135 predominantly African American patients with HIV and positive PTSD screens in a primary care unit. The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) and a retrospective chart review of 135 patients with HIV were conducted. On the PCPTSD-5 (cut point of 3), approximately one half of patients (49.6%; n = 67) had probable PTSD; however, only 11.9% of patients (n = 16) had a chart diagnosis of PTSD. A positive PTSD screen was associated with higher rates of depression and insomnia, but not anxiety, alcohol use, drug use, or pain in patients with HIV. Multi-morbidity of HIV, major depression, and positive PTSD screens was associated with increased risk for asthma, number of medical diagnoses, depression, insomnia, and anxiety. Findings highlight the need for trauma-informed care in primary care settings for people with PTSD and HIV. Larger samples are warranted to further explore health correlates of PTSD.

Undocumented PTSD among African American clients with serious mental illness in a statewide mental health system.

OBJECTIVES: African Americans are at increased risk for trauma exposure and the development of posttraumatic stress disorder (PTSD) relative to other racial groups. Among African Americans with Serious Mental Illness (SMI), PTSD is frequently underdiagnosed and untreated. The primary objective of this study was to investigate trauma exposure, PTSD symptom severity, and the rate of undocumented PTSD in medical records among African Americans diagnosed with SMI. METHODS: Screening for trauma exposure and PTSD symptoms was implemented among 404 clients receiving community mental health services. Participants endorsed at least 1 traumatic event, had a score of at least 45 on the DSM-IV PTSD Checklist indicating probable PTSD, and had a chart diagnosis of an Axis I disorder. RESULTS: Around 18.3% of participants had PTSD diagnosed in their medical chart. A diagnosis of schizophrenia/schizoaffective disorder was inversely related to the detection of PTSD in the chart. Client age and gender did not adversely affect the detection of PTSD, and detection rates remained low overall. Childhood sexual abuse was the most commonly endorsed index trauma, followed closely by sudden death of a loved one (including violent death). Participants typically experienced an average of 8 types of traumatic events in their lifetime. Cumulative total trauma exposure significantly predicted PTSD severity. Clients with mood disorders reported more severe PTSD. CONCLUSION: Findings highlight the low detection rate of PTSD and related symptoms in African American clients with SMI. There is a need for early intervention, grief counseling, culturally sensitive trauma screening, and culturally informed treatment options for this population.

Trauma Exposure and Prolonged Grief Disorder Among Persons Receiving Community Mental Health Services: Rates and Correlates.

BACKGROUND: Persons with serious mental illnesses (SMIs) are at increased risk for exposure to trauma and posttraumatic stress disorder (PTSD). Prolonged Grief Disorder (PGD) may also impact this population but has been seldom studied. AIMS: The present study investigated the rate of both PTSD and PGD among clients receiving community mental health services, and the clinical correlates of co-occurring PTSD/PGD. METHODS: Trauma history, PTSD and PGD were assessed among 536 individuals receiving community mental health services (Study 1). A subsample of 127 individuals from Study 1 who met DSM-5 criteria for PTSD based on diagnostic interview completed measures of psychiatric symptoms (Study 2). RESULTS: In Study 1, 92.4% of participants receiving community mental health services had experienced a traumatic event, 49.6% met criteria for probable and provisional PTSD, 14.7% scored positive for probable PGD, and 11.9% met criteria for probable and provisional PTSD as well as probable PGD. In Study 2, participants meeting diagnostic DSM-5 criteria for PTSD and probable PGD had more self-reported PTSD symptoms, but did not differ on other outcomes. CONCLUSIONS: Findings highlight the need for trauma informed services including grief counseling for persons with SMI.
