Predictors of response to brief CBT in patients with cardiopulmonary conditions.

Abstract

This study examined predictors of treatment outcome in a randomized controlled trial of brief cognitive-behavioral therapy (bCBT) for patients with a cardiopulmonary condition and comorbid, clinically significant symptoms of depression and/or anxiety. Only those who completed outcome assessments in the bCBT arm were studied (n = 132), to provide information about predictors of change in psychological symptoms. Multivariable linear regressions were conducted with baseline depression and anxiety symptoms, functional limitations, coping, self-efficacy, number of treatment sessions attended, and working alliance as potential predictors of change from pre- to postintervention on the dependent variables, depression [Patient Health Questionniare-9] and anxiety [Beck Anxiety Inventory]). Significant predictors of improvement in depression and anxiety included baseline mental health symptoms, physical health functional impairment, and self-efficacy. Coping, working alliance, and number of sessions attended were not associated with change in depression or anxiety. Patients with greater physical functioning limitations and lower self-efficacy may experience less change in depression and anxiety during brief CBT. Future research should examine how to boost treatment effectiveness for patients with these characteristics. (PsycINFO Database Record
