Multidimensional Cognitive Behavioral Therapy for Obesity Applied by Psychologists Using a Digital Platform:...

Area of Science:

• Behavioral Science
• Digital Health
• Obesity Research

Background:

• Obesity is a significant global health issue requiring effective weight management strategies.
• Developing widely applicable and successful weight management programs remains a priority in healthcare.

Purpose of the Study:

• To develop and evaluate a novel, comprehensive, multifactorial digital program incorporating psychologist coaching based on cognitive behavioral therapy (CBT) modules.
• To investigate the efficacy of this digital CBT intervention delivered via mobile health services for weight management.

Main Methods:

• An open-label, randomized controlled trial involving 70 female participants with BMI > 24 kg/m².
• Participants were randomized into a digital CBT group with therapist support or a control group with self-care via a digital health service for 8 weeks.
• Outcomes including weight, body composition, and eating behaviors were measured at baseline, 8 weeks, and 24 weeks.

Main Results:

• The digital CBT group achieved significantly greater weight loss (-3.1% vs -0.7%) and fat mass reduction (-6.3% vs -0.8%) at 8 weeks compared to the control group.
• Significantly higher proportions of the digital CBT group reached 5% weight loss at 8 weeks (32% vs 4%).
• Improvements were observed in leptin levels, insulin resistance, emotional eating behaviors, and reduced snack calorie intake in the digital CBT group.

Conclusions:

• Technology-based weight management interventions are most effective when multidimensional, incorporating human feedback and support.
• The developed digital CBT program, supported by a multidisciplinary team, demonstrated significant efficacy in weight management.
• This study validates a novel, technology-driven CBT approach for obesity treatment.
