背景使用轮椅的自我效能感是轮椅使用文献中的一个新兴结构，它可能对轮椅使用者的社会和个人角色的参与频率产生影响。目的探讨自我效能感对50岁及以上社区体力轮椅使用者参与频率的直接和中介效应。设计：横断面研究。方法研究对象为社区居民轮椅使用者(N=124)，年龄在50岁以上(平均59.7岁)，至少有6个月轮椅使用经验。晚年残障量表、轮椅使用信任量表、生活空间评估和轮椅技能测验问卷版分别测量了参与频率、自我效能、生活空间流动性和轮椅技能。采用自助法进行多元回归分析，考察直接效应和中介效应。分析使用了《国际功能、残疾和健康分类》。结果自我效能感是参与频率的显著决定因素，在控制了年龄、合并症数量和社会支持后，自我效能感可以解释参与变量的17.2%。生活空间机动性、轮椅技能和知觉参与限制的总中介效应具有统计学意义(点估计=0.14；自举95%可信区间=0.04，0.24)；然而，轮椅技能变量的特定间接效应对高于其他两个中介变量的总效应没有贡献。中介模型解释了参与变量的55.0%。由于数据的横截面性质，无法确定限制因果关系，来自志愿者样本的数据的自我报告性质可能受到测量偏差或社会合意性的影响，或两者兼而有之。结论自我效能感直接和间接影响50岁及以上社区手动轮椅使用者的参与频率。制定干预措施来解决低自我效能感是必要的。
Background Self-efficacy with using a wheelchair is an emerging construct in the wheelchair-use literature that may have implications for the participation frequency in social and personal roles of wheelchair users. Objectives The aim of this study was to investigate the direct and mediated effects of self-efficacy on participation frequency in community-dwelling manual wheelchair users aged 50 years or older. Design A cross-sectional study was conducted. Methods Participants were community-dwelling wheelchair users (N=124), 50 years of age or older (mean=59.7 years), with at least 6 months of experience with wheelchair use. The Late-Life Disability Instrument, the Wheelchair Use Confidence Scale, the Life-Space Assessment, and the Wheelchair Skills Test–Questionnaire Version measured participation frequency, self-efficacy, life-space mobility, and wheelchair skills, respectively. Multiple regression analyses with bootstrapping were used to investigate the direct and mediated effects. The International Classification of Functioning, Disability and Health was used to guide the analyses. Results Self-efficacy was a statistically significant determinant of participation frequency and accounted for 17.2% of the participation variance after controlling for age, number of comorbidities, and social support. The total mediating effect by life-space mobility, wheelchair skills, and perceived participation limitations was statistically significant (point estimate=0.14; bootstrapped 95% confidence interval=0.04, 0.24); however, the specific indirect effect by the wheelchair skills variable did not contribute to the total effect above and beyond the other 2 mediators. The mediated model accounted for 55.0% of the participation variance. Limitations Causality cannot be established due to the cross-sectional nature of the data, and the self-report nature of our data from a volunteer sample may be influenced by measurement bias or social desirability, or both. Conclusion Self-efficacy directly and indirectly influences the participation frequency in community-dwelling manual wheelchair users aged 50 years or older. Development of interventions to address low self-efficacy is warranted.
