Sensitivity and specificity of the PTSD checklist in detecting PTSD in female veterans in primary care

PTSD affects a substantial number of women in medical settings and is associated with significant distress and impairment. There are effective methods of treating trauma-related distress, but a minority seek such care. Thus, primary care is an important setting in which to identify individuals with PTSD. We sent questionnaires, including the PTSD Checklist—Civilian Version (PCL-C), to 419 female veterans who were seen in our primary care clinic in 1998; 56% (N = 221) returned the measures. A random subset (n = 49) was interviewed to establish psychiatric diagnoses. The results provide qualified support for the use of the PCL-C total score with a lowered cutoff score as a screening measure for PTSD in female veterans in primary care.

Depression in a primary care clinic : The prevalence and impact of an unrecognized disorder

BACKGROUND This study assesses depression among primary care patients, the relationship between depression and functioning, and how frequently depressed individuals receive mental health treatment. METHODS Two hundred and thirteen participants completed a diagnostic interview and measures of functional impairment and service utilization. RESULTS Sixty-two clinic patients were depressed, and depressed individuals experienced significant functional impairment even after controlling for comorbid anxiety disorders and medical problems. However, less than 40% of depressed individuals were receiving treatment for depression. Severity of impairment was related to likelihood of receiving mental health services. LIMITATIONS Several factors to consider when evaluating this study are the cross-sectional design, use of self-report data, and lack of random sampling. CONCLUSIONS These results show that depression has a unique and significant impact on the functioning of primary care patients, and emphasize the need for identification of depressive disorders in primary care.

Sexual Trauma, Posttraumatic Stress Disorder, and Health Behavior

Abstract The authors tested whether sexual traumatization is associated with poorer health behavior and also evaluated the role of posttraumatic stress disorder (PTSD) in this relationship. They mailed questionnaires to 419 women who had visited a San Diego Veterans Administration primary care clinic in 1998 and received 221 responses, a 56% return rate. They found that a history of sexual assault was associated with increased substance use, risky sexual behaviors, less vigorous exercise, and increased preventive healthcare. They then used regression-based techniques to test whether PTSD mediates the relationship between a history of sexual assault and health behaviors and discovered support for this hypothesis in relation to substance use. PTSD symptoms were also associated with less likelihood of conducting regular breast self-examinations. Findings from the study highlight the value of programs designed to (1) identify trauma victims, (2) screen for problematic behaviors, and (3) intervene to improve long-term health outcomes.

Post-traumatic stress disorder and health-related quality of life in female victims of intimate partner violence.

The association between post-traumatic stress disorder (PTSD) and health-related quality of life (QOL) in female victims of intimate partner violence (IPV) was examined. The Short-Form Health Survey (SF-36) was used to evaluate health-related QOL. IPV victims with PTSD (IPV/PTSD+; n = 18), IPV victims without PTSD (IPV/PTSD-; n = 22), and a non-abused control group (NA; n = 30) were compared. Multiple Analyses of Covariance (covarying for socioeconomic status and age) indicated that the three groups scored significantly differently on health-related QOL, and the IPV/PTSD- group was significantly more impaired than the NA group. IPV/PTSD+ subjects were significantly more impaired than IPV/PTSD- subjects on physical functioning, mental health, vitality, role limitations due to emotional health, and social functioning. Multiple regression analyses indicated that PTSD severity was a significant statistical predictor of SF-36 mental health composite scores (but not of physical health composite scores), after controlling for depressive symptomatology and extent of physical and psychological abuse.

An evaluation of the psychometric properties of the traumatic events questionnaire in primary care patients

This study examined the reliability of reports of traumatic experiences across the Traumatic Events Questionnaire (TEQ; S. Vrana & D. Lauterbach, 1994) and the Composite International Diagnostic Interview (CIDI; World Health Organization, 1998), and evaluated other psychometric properties of the TEQ in 154 primary care patients. Agreement rates for various traumatic experiences were moderate to substantial, with sexual abuse showing 87% agreement, and other forms of trauma exhibiting rates from 81-74%. The TEQ yields a trauma intensity score, which produced stronger correlations with self-reported PTSD symptoms and problematic anger than the sum of traumas experienced. Trauma intensity also proved to be a powerful predictor of posttraumatic stress disorder (PTSD) diagnostic status. Results support the TEQ as a measure of traumatic exposure in primary care populations.
