Feasibility and Preliminary Effects of a WeChat Mini Program-Based Positive Psychology Intervention in Patients With Coronary Heart Disease: A Nonrandomized Controlled Pilot Trial.
ABSTRACT
Background:
Psychological problems are highly prevalent among patients with coronary heart disease (CHD) and are associated with poor health behaviors. A WeChat mini program-based positive psychology intervention may alleviate psychological distress and promote healthier behaviors.
Objective:
This study aimed to assess the feasibility, acceptability, and preliminary efficacy of a WeChat mini program-based positive psychology intervention in improving psychological and health behavior motivation outcomes in patients with CHD, compared with a control group.
Methods:
This was a parallel-group, non-randomized controlled pilot study. Participants were assigned to either a WeChat mini program-based positive psychology intervention (WPP) plus usual care or a health education control group (HEG). Feasibility and acceptability were assessed using recruitment, retention, and completion rates. Psychological outcomes and health behavior motivation were assessed using validated self-report questionnaires at baseline and after the 6-week intervention. Linear mixed-effects models with fixed effects for group, time, and group-by-time interaction and random intercepts for participants were used to assess between-group differences over time.
Results:
A total of 60 participants were enrolled, and 55 (91.7%) completed the 6-week intervention (28 in the WPP group and 27 in the HEG group). The intervention demonstrated high engagement and acceptability among participants. Baseline characteristics were comparable between groups. Linear mixed models revealed significant Group×Time interaction effects for all outcomes (all P < .05). Compared with the HEG group, the WPP group demonstrated significant improvements in subjective well-being (F(1, 53) = 33.80, P < .001), positive affect (F(1, 53) = 45.61, P < .001), and reductions in negative affect (F(1, 53) = 48.66, P < .001). Additionally, significant interaction effects were observed for smoking cessation motivation (F(1, 53) = 70.72, P < .001), healthy diet motivation (F(1, 53) = 79.14, P < .001), and regular exercise motivation (F(1, 53) = 73.66, P < .001).
Conclusions:
The WeChat mini program-based positive psychology intervention was feasible, acceptable, and.showed promising preliminary effects on psychological well-being, affect, and health behavior motivation in patients with CHD. Further large-scale randomized controlled trials are warranted to confirm these findings and to examine long-term outcomes. Clinical Trial: trial registration: under review
