Exploratory and Confirmatory Analysis of the Trauma Practices Questionnaire

Objective: The present study provides psychometric data for the Trauma Practices Questionnaire (TPQ). Method: A nation-ally 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 approxima-tion [RMSEA] =.07). Post hoc modifications significantly improved model fit (CFI =.95 and RMSEA =.06). Alpha relia-bilities ranged from.72 to.82. Conclusions: The TPQ has evidence of validity for assessing trauma practice patterns among clinical social workers and clinical psychologists
