虽然之前的研究表明自我效能感和体力活动之间存在显着关系，但很少有研究关注 2 型糖尿病患者的这种关系。本次调查的目的是检验自我效能感是否介导了参与为期 1 个月的基于印刷品的身体活动干预与活动水平改善之间的关系。 参与者（N = 85；平均年龄 = 57；73% 白人；69% 女性）是从社区糖尿病中心招募的。该干预措施是根据包括自我效能在内的理论结构进行个性化定制的。在控制了年龄、基线活动和基线自我效能后，定制的干预措施与体力活动（95% CI [23.01, 271.68]）以及自我效能（CI [0.02, 3.48]）的显着改善相关。治疗通过自我效能对体力活动产生间接影响，CI [0.77, 73.11]，而在模型中考虑自我效能变化的影响后，治疗对体力活动的直接影响不再显着，CI [-7.33, 253.40]。结果支持中介效应，即治疗对体力活动的影响完全由自我效能的变化介导。尽管需要复制，但结果支持了以自我效能为目标来促进 2 型糖尿病患者身体活动的理论依据。
While previous studies indicate a significant relationship between self-efficacy and physical activity, less research has focused on this relationship among patients with type 2 diabetes. The purpose of this investigation was to examine whether self-efficacy mediated the relationship between participation in a 1-month, print-based physical activity intervention and improvements in activity levels.Participants (N = 85; mean age = 57; 73% Caucasian; 69% female) were recruited from a community diabetes center. The intervention was individually-tailored based on theoretical constructs, including self-efficacy.After controlling for age, baseline activity, and baseline self-efficacy, the tailored intervention was associated with significant improvements in physical activity, 95% CI [23.01, 271.68] as well as self-efficacy, CI [0.02, 3.48]. There was an indirect effect of treatment on physical activity through self-efficacy, CI [0.77, 73.11], and the direct effect of treatment on physical activity was no longer significant, CI [-7.33, 253.40], after the influences of self-efficacy change were accounted for in the model.Results supported a mediation effect, such that the treatment effect on physical activity was completely mediated by changes in self-efficacy. Although replication is needed, results support the theoretical rationale for targeting self-efficacy to promote physical activity among patients with type 2 diabetes.
