Examination of psychometric properties of the Posttraumatic Stress Related Functioning Inventory, Revised (PRFI-5) in veterans.

OBJECTIVE: version of the PRFI (PRFI-5). METHOD: = 450). Psychometric analyses included a review of item and scale descriptives, evaluation of the scale's reliability and cohesiveness, assessment of the scale factor structure, and its convergent and discriminant validity. RESULTS: Broadly, results were similar to those of the previous version of the PRFI and support the PRFI-5 as a reliable (αs = .70-.97) and valid measure of posttraumatic stress-related functional impairment. The measure can provide a high-level summary of functioning (e.g., total scale score) yet also can be used to provide a detailed clinical analysis of psychosocial functioning across several domains (i.e., work/school, relationships, lifestyle). CONCLUSIONS: This study examines a pragmatic measure of PTSD-related psychosocial functioning and highlights the importance of incorporating a measure of psychosocial functioning routinely alongside symptom measures as a component of psychological assessment and practice.
