Explain the behavior change and maintenance in diabetic patients using MTM-HAPA framework

Area of Science:

• Behavioral Science
• Health Psychology
• Diabetes Management

Background:

• Understanding factors influencing health behaviors is crucial for managing diabetes mellitus (DM).
• Existing models may not fully capture the complexities of behavior change in DM patients.
• Integration of theoretical frameworks can provide a more comprehensive understanding.

Purpose of the Study:

• To identify factors influencing the initiation and maintenance of health behaviors in diabetes mellitus (DM) patients.
• To construct and test a structural equation model based on the Multi-Theory Model (MTM) and Health Action Process Approach (HAPA) scales.
• To utilize baseline data from a randomized controlled trial for model development.

Main Methods:

• Recruited 406 participants with type 2 diabetes (aged 18-75) from 45 locations in Beijing, China.
• Employed self-reported questionnaires assessing constructs from integrated health behavior theories.
• Utilized structural equation modeling (SEM) with latent variables to test hypotheses and path coefficients.

Main Results:

• Perceived disadvantages negatively impacted intention; intention positively influenced action and coping planning, predicting behavior initiation.
• Outcome expectancies and risk perception positively affected practice for change, emotional transformation, social environment changes, and self-efficacy for sustaining behavior.
• These factors significantly predicted the maintenance of behavioral change.

Conclusions:

• The integrated MTM-HAPA model demonstrates significant explanatory power for health behavior initiation and maintenance in DM patients.
• Empirical validation supports the theoretical constructs underpinning behavior change in this population.
• Findings offer valuable insights for designing effective interventions for diabetes self-management.
