Exploratory and Confirmatory Analysis of the Trauma Practices Questionnaire

Abstract

Objective: The present study provides psychometric data for the Trauma Practices Questionnaire (TPQ). Method: A nationally randomized sample of 2,400 surveys was sent to self-identified trauma treatment specialists, and 711 (29.6%) were returned. Results: An exploratory factor analysis (N = 319) conducted on a randomly split sample (RSS) revealed a 19-item, six-factor structure. A confirmatory factor analysis was conducted for the six-factor model on the second RSS (N = 320). The hypothesized model demonstrated adequate fit (comparative fit index [CFI] = .94 and root mean square error of approximation [RMSEA] = .07). Post hoc modifications significantly improved model fit (CFI = .95 and RMSEA = .06). Alpha reliabilities ranged from .72 to .82. Conclusions: The TPQ has evidence of validity for assessing trauma practice patterns among clinical social workers and clinical psychologists.
