摘要
目的探讨社会问题解决对减重效果的影响机制,自我控制和饮食自我效能的链式中介效应,社会问题解决对体重变化趋势的预测效应。方法采用饮食自我效能量表、社会性问题解决量表,自我控制量表对减重者进行在线问卷调查;用SPSS 26.0检验健康饮食的干预效果,使用PROSS V3.4建立回归模型检验自我控制和饮食自我效能的中介作用,社会问题解决对体重趋势的预测作用。结果(1)健康饮食干预后,饮食自我效能前后差异显著(t=-7.97,P<0.001);(2)社会性问题解决中的积极问题倾向不仅能直接显著正向预测减重效果,而且还能通过干预后饮食自我效能的中介作用及自我控制-干预后饮食自我效能的链式中介作用,间接影响减重效果;(3)社会性问题解决中的理性问题解决虽然不能直接显著预测减重效果,但是可以通过自我控制的中介作用及自我控制-干预后饮食自我效能的链式中介作用,间接影响减重效果;(4)社会性问题解决可以显著预测减重者离开减脂班后未来的体重变化趋势。结论改善个体的社会性问题解决能力,使之从消极等非理性问题解决方式转化为积极理性的问题解决方式,提高自我控制能力,增强饮食自我效能,可以有效的控制和维持体重,提高个体的幸福感和生活满意度。
Objective To study the mechanism of social problem solving on weight loss,the chain mediating effects of self-control and dietary self-efficacy,and the predictive effects of social problem solving on weight change trends.Methods An online questionnaire was conducted to dieters with Dietary Self-Efficacy Scale,Social Problem-Solving Scale,and the Self-Control Scale.SPSS 26.0 was applied to test the intervention effects of healthy diet,the mediating effects of self-control and dietary self-efficacy and the predictive effects of social problem solving on weight trends were examined through regression models established by using PROSS V3.4.Results(1)The dietary self-efficacy before and after eating was significantly different after the healthy diet intervention(t=-7.97,P<0.001);(2)Positive tendencies in social problem solving not only directly and significantly predicted weight loss effects,but also indirectly affected weight loss effects through the mediating role of post-intervention dietary self-efficacy and the chain mediating role of self-control-post-intervention dietary self-efficacy.(3)Rational problem solving in social problem solving could not directly and significantly predict weight loss effects,but was able to indirectly affect weight loss effects through the mediating role of self-control and the chain mediating effect of self-control-post-intervention dietary self-efficacy.(4)Social problem solving can significantly predict weight change trend after dieters terminate the weight-loss programs.Conclusion Weight could be controlled and maintained,while life satisfaction and happiness could be fulfilled,through improving individuals'social problem solving ability,transforming from negative and irrational problem solving to positive and rational problem solving,strengthening self-control ability and enhancing dietary self-efficacy.
