The fourth edition of the Generalized Anxiety Disorder Questionnaire (GAD-Q-IV) is a self-report measure that is commonly used to screen for the presence of generalized anxiety disorder (GAD). The current investigation attempted to identify an optimal cut score using samples obtained from an outpatient psychiatric (n=163) and primary care clinic (n=99). Results indicated that a cut score of 7.67 provided an optimal balance of sensitivity (.85) and specificity (.74) comparable to a previously identified cut score (5.7) across both samples (sensitivity=.90, specificity=.66). However, both cut scores were consistently outperformed by a score representing the criteria for GAD described in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (sensitivity=.89, specificity=.82).

Comparative Study
Evaluating treatment of posttraumatic stress disorder with cognitive processing therapy and prolonged exposure therapy in a VHA specialty clinic.
This retrospective chart review evaluates the effectiveness of manualized cognitive processing therapy (CPT) protocols (individual CPT, CPT group only, and CPT group and individual combined) and manualized prolonged exposure (PE) therapy on veterans' posttraumatic stress disorder (PTSD) symptoms in one Veterans Health Administration (VHA) specialty clinic. A total of 517 charts were reviewed, and analyses included 178 charts for CPT and 85 charts for PE. ⋯ Additional findings included different outcomes among CPT formats, decreased treatment dropouts for older veterans, and no significant differences in outcome between Hispanic and White veterans. Study limitations and future research directions are discussed.
