Cognitive-behavioral therapy (CBT) is skill based and assumes active patient participation in regard to treatment-related assignments. The effects of patient compliance in CBT outcome studies are equivocal, however, and 1 gap in the literature concerns the need to account for the quality versus the quantity of assigned work. In this study, both quality and quantity of home-based practice were assessed to better evaluate the effects of treatment compliance in patients with panic disorder (N = 48) who participated in a 12-session CBT protocol. Patient estimates of compliance were not significantly associated with most outcome measures. On the other hand, therapist ratings of compliance significantly predicted positive changes on most outcome measures. Moreover, therapist and independent rater estimates of the quality of the participant's work, relative to the quantity of the work, were relatively better predictors of outcome.
Cognitive-behavioral treatment (CBT) protocols for panic disorder (PD) consist of a set of interventions that often includes some form of breathing retraining (BR). A controlled outcome study was designed to assess the necessity of BR in the context of a multicomponent CBT protocol. To accomplish this, patients with PD (N = 77) were randomly assigned to receive CBT with or without BR or to a delayed-treatment control. The main study hypothesis was that patients receiving BR would display a less complete recovery relative to the other active-treatment condition given that BR appears to be a more attractive (but less adaptive) option for some patients. Some data suggested that the addition of BR yielded a poorer outcome. However, findings were generally more consistent with treatment equivalence, questioning whether BR produces any incremental benefits in the context of other CBT interventions for PD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
