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.
