Comparing the acceptability of a positive psychology intervention versus a cognitive-behavioral therapy for clinical depression.

Abstract

There is growing evidence on the efficacy of positive psychology interventions (PPI) to treat clinical disorders. However, very few studies have addressed their acceptability. The present study aimed to analyze two key components of acceptability (i.e., client satisfaction and adherence to treatment) of a new PPI programme, the Integrative Positive Psychological Intervention for Depression (IPPI-D), in comparison to a standard CBT programme in the treatment of clinical depression. One hundred twenty-eight women with a DSM-IV diagnosis of major depression or dysthymia were allocated to a 10-session IPPI-D or CBT group intervention condition. Results showed that both interventions were highly acceptable for participants. Attendance rates were high and there were no significant differences between conditions. However, the IPPI-D condition showed significantly higher client satisfaction than the CBT condition. Moreover, acceptability did not differ based on participants’ severity of symptoms, regardless of condition. These findings encourage further investigations of the applicability of PPI in clinical settings in order to broaden the range of acceptable and suitable therapies for depressed patients.
