Prediction of outcome for veterans with post-traumatic stress disorder using constructs from the transtheoritical model of bahaviour change

Abstract

Objective: Post-traumatic stress disorder (PTSD) is a disabling condition, sometimes unresponsive to treatment. The aim of the present study was to examine the predictive utility of constructs from the transtheoretical model of behaviour change (TTM) known to predict outcome for other disorders. Method: A sample of 50 veterans presenting for a PTSD treatment programme provided data for this longitudinal study. Variables were assessed at four time-points during the treatment programme. Multiple regression and mixed-effects regression were utilized to determine the predictive utility of variables from the TTM. Results: Allocated stage of change at the time of a 2 day introduction programme pre..
