Key Points
This research aims to explore how user perceptions of persuasive systems and their characteristics influence weight loss outcomes in obesity management.
Randomized controlled trial with 96 participants
Analysis of waist circumference reduction after 6 months using mobile health support system
Utilization of Partial Least Squares Structural Equation Modeling for data analysis.
SOC accounts for 22.2% of waist circumference reduction variance
High perceived persuasiveness of the system led to higher progress through SOC (R² = 0.119)
Dialogue Support and Primary Task Support explained 55% of the variance in perceived persuasiveness.
