A Cognitive Behavioral Therapy-Based Lifestyle Modification Intervention for Chinese Older Adults With Osteoarthritis.

Purpose: The aim of the study was to develop a cognitive behavioral therapy (CBT)-grounded and tablet-based lifestyle modification intervention for Chinese older adults with osteoarthritis ("CBT-OA") and examine the CBT-OA's usability.

Design: A descriptive exploratory design was used in this study.

Methods: Using an iterative user-centered design approach, we developed the CBT-OA and evaluated its usability to identify any initial design issues (Phase 1) and if the CBT-OA was integrated into participants' daily living (Phase 2).

Results: In Phase 1 (n = 5), participants perceived the CBT-OA as easy to use and an excellent way to structure self-care. In Phase 2 (n = 15), the participants reported the CBT-OA as effective (completion rate = 85%-100%), efficient (0.01-0.29 task/second), and usable (mean System Usability Scale = 70.48, SD = 9.94). They recognized two benefits as a motivator and improvement of self-management confidence and the SMART goal setting as the most preferred component. Suggestions for improvement include adding more videos to visually demonstrate steps of cooking healthy Chinese meals and having a forum to share ideas and experiences.

Clinical relevance and conclusion: Use of technology to improve chronic health outcomes and quality of life continues to grow. CBT-OA is one such application designed specifically for Chinese older adults with osteoarthritis. The findings indicate CBT-OA holds promise for improving arthritis outcomes.
