Ongoing concerns exist in the literature regarding the construct of posttraumatic stress disorder (PTSD) and how to best conceptualize and measure this disorder. We compared the traditional DSM-IV PTSD symptom criteria (i.e., symptoms from clusters B, C, and D) to a revised criterion set that omits overlapping mood and other anxiety symptoms on PTSD prevalence, PTSD diagnostic caseness, associated psychiatric comorbidity, functional status, and structural validity using a cross-sectional, multi-site primary care sample of 747 veterans. After removing items theorized to overlap with mood and other anxiety disorders, PTSD prevalence was identical using both criterion sets (i.e., 12%). Overall, there …

All ETDs from UAB
A measurement study was conducted to evaluate 11 items representing the latent variable labeled "sense of community" (SOC) employed by investigators of the Mobile Youth Survey (MYS). In previous research the 11 items representing the concept of SOC have been combined to form a composite variable, assuming that the concept was best represented by a single factor (e.g., Bolland, Bryant, Lian, McCallum, Vazsonyi & Barth, 2007). However, no systematic analysis has been conducted to determine the psychometric properties of the 11-item composite variable. The objects of the present study are a) to determine the component structure of the items used …
