The purpose of this study was to investigate the strength of the relationships between self-efficacy and (i) functional exercise capacity and (ii) physical activity in chronic obstructive pulmonary disease (COPD), and whether self-efficacy assessment type (i.e., COPD symptoms, exercise-task, exercise-barrier, general, falls) and physical activity assessment type (i.e., self-report vs. objective) are moderators. A systematic search of COPD and self-efficacy concepts was conducted using eight databases from inception to 23 January 2019. Studies were included if they provided correlation coefficients of the relationship between self-efficacy and functional exercise capacity or physical activity, were conducted in adults diagnosed with COPD, and were published in English-language journals. A total of 14 correlation coefficients were included in the self-efficacy and functional exercise capacity meta-analysis, and 16 in the self-efficacy and physical activity meta-analysis. Data were screened, reviewed, and extracted independently by two reviewers, with discrepancies resolved by a third reviewer. Stronger self-efficacy was associated with better functional exercise capacity (weighted = 0.38, 95%CI [0.25, 0.50]), and greater physical activity (weighted = 0.25, 95%CI [0.17, 0.34]). Exercise-task self-efficacy had the strongest relationship to functional exercise capacity (weighted = 0.64, 95% CI [0.51, 0.73]). For physical activity, the type of self-efficacy most strongly related was inconclusive. In COPD, self-efficacy has a relationship to functional exercise capacity and physical activity, the strength of which is influenced by the choice of self-efficacy measure. An understanding of these relationships will assist clinicians in selecting the self-efficacy measure most closely related to the outcome of interest.
本研究旨在探讨自我效能感与（i）慢性阻塞性肺疾病（COPD）的功能运动能力和（ii）身体活动之间的关系强度，以及自我效能评估类型（即 COPD 症状、运动任务、运动障碍、一般、跌倒）和身体活动评估类型（即自我报告与客观）是否存在调节作用。通过对八个数据库进行系统搜索，从成立到 2019 年 1 月 23 日，对 COPD 和自我效能感的概念进行了搜索。如果研究提供了自我效能感与功能运动能力或身体活动之间关系的相关系数，并且是针对成年人诊断为 COPD 的患者进行的，并且是用英语发表的期刊，则将这些研究纳入研究。自我效能感与功能运动能力的荟萃分析中包含了 14 个相关系数，自我效能感与身体活动的荟萃分析中包含了 16 个相关系数。两位审查员独立筛选、审查和提取数据，如果存在分歧，则由第三位审查员解决。较强的自我效能感与更好的功能运动能力（加权平均值为 0.38，95%置信区间 [0.25，0.50]）和更高的身体活动（加权平均值为 0.25，95%置信区间 [0.17，0.34]）相关。运动任务自我效能感与功能运动能力的关系最强（加权平均值为 0.64，95%置信区间 [0.51，0.73]）。对于身体活动，与自我效能感最相关的类型尚不确定。在 COPD 中，自我效能感与功能运动能力和身体活动有关，其强度受自我效能感测量的选择影响。了解这些关系将有助于临床医生选择与感兴趣的结果最相关的自我效能感测量。
