Cognitive Behavioral Therapy (CBT) Telehealth Augmented With a CBT Smartphone Application to Address Type 2 Diabetes Self-Management: A Randomized Pilot Trial

Abstract

Purpose: The purpose of the study was to investigate the feasibility and acceptability of phone-delivered cognitive behavioral therapy (CBT) combined with an adjunctive smartphone application CBT MobileWork-DM© to improve self-management of type 2 diabetes mellitus (T2DM). Methods: Participants were 12 patients with T2DM on antihyperglycemic medication and had an A1C level of 8 or greater. A randomized controlled pilot study assessed treatment as usual (TAU) T2DM care versus a phone-delivered CBT (6, 8, or 12 weekly sessions) augmented with a CBT skills practice smartphone application. The CBT telehealth intervention addressed T2DM self-management and diabetes distress. Electronic and self-report medication taking, diabetes-related distress, and A1C were assessed at baseline and post-intervention. Results: After 16 weeks, a decrease in A1C and distress levels was observed in all 3 CBT phone groups and TAU group. The group with the most improvement was the 12-week CBT group, which had the greatest mean decrease in A1C (−2.33) and diabetes distress (−31.67). The TAU group exhibited a mean decrease of −2.15 and −21 for A1C and diabetes distress, respectively. The overall rate of completion for phone CBT sessions across the 3 CBT groups was 83%. Conclusion: This study demonstrates that telehealth CBT augmented with a smartphone application is feasible and acceptable. Patients demonstrated improvements in both T2DM management and distress.
