Therapeutic factors affecting the cognitive behavioral treatment of bulimia nervosa via telemedicine versus face-to-face delivery.

OBJECTIVE Recently, Mitchell et al. (Behav Res Ther, 46, 581-592, 2008) conducted a randomized controlled trial of an empirically supported treatment for bulimia nervosa (BN) delivered face-to-face (FTF-CBT) or via telemedicine (TV-CBT). Results suggested that the TV-CBT and FTF-CBT were generally equivalent in effectiveness. The objective of the current study was to examine ratings of therapeutic alliance factors in TV-CBT and FTF-CBT. METHOD Data obtained from 116 adults who met criteria for BN or eating disorder-not otherwise specified with binge eating or purging weekly and six doctoral-level psychologists who delivered the therapy were used in the analyses. RESULTS Therapists generally endorsed greater differences between the treatment delivery methods than patients. Patients tended to make significantly higher ratings of therapeutic factors than therapists. DISCUSSION TV-CBT is an acceptable method for the delivery of BN treatment compared to FTF-CBT, and TV-CBT is more easily accepted as a treatment delivery method by patients than therapists.
