Objective
To date, transdiagnostic treatments have primarily investigated treatment outcomes of general psychiatric symptomatology, rather than the specific transdiagnostic symptoms implicated in their protocols. The present study sought to address this significant gap in the literature by investigating the effect of transdiagnostic behavior therapy (TBT) on transdiagnostic avoidance.
Method
Forty‐four veterans diagnosed with various emotional disorders initiated TBT, and completed diagnostic and self‐report measures at pre‐ and posttreatment.
Results
Participants demonstrated reliable treatment improvements in measures of situational, thought, and positive emotional avoidance, with moderate‐to‐large effect sizes, and in measures of physical/interoceptive avoidance with small‐to‐medium effect sizes.
Conclusions
The findings support the hypothesized effect of TBT in self‐report measures of four types of transdiagnostic avoidance in participants diagnosed with various emotional disorders. These findings contribute to the growing literature on the potential benefits of the transdiagnostic approaches to address symptomatology across diagnoses.
