目的尽管有大量的观察和实验测试，但尚不清楚增强自主动机或感知能力是否会导致健康行为改变。我们确定了旨在改变这些结构的干预措施，并量化了当干预措施提高自主动机、感知能力或两者兼而有之时观察到的行为变化的程度。方法计算机化搜索和其他策略确定了 67 篇文章，产生了与我们的研究问题相关的 135 个效应大小。通过 STATA 进行随机效应荟萃分析。结果 在 31% 和 38% 的测试中，干预措施分别提高了自主动机和感知能力。自主动机的增加导致健康行为发生中等变化（d+=. 47, 95% CI [. 44,. 83]），而感知能力的增加则产生小到中等的变化（d+=. 34, 95% CI [. 22,. 47]）。未能显着改善自主动机和感知能力的干预措施对行为改变的影响要小得多（分别为 d+=.13 和.10）。几乎没有证据表明存在协同效应。与改变自主动机（d+=.61）相比，改变自主动机和感知能力（d+=.42）不会对行为产生更大的影响，但与改变感知能力（d+=.21）相比，会产生更大的影响。结论本综述表明，自主动机和感知能力是促进健康行为改变的干预措施的有效目标，但也表明有必要进行研究，以确保干预措施更有效地涉及这些目标。
ObjectiveDespite abundant observational and experimental tests, it is not yet clear whether enhancing autonomous motivation or perceived competence leads to health behavior change. We identified interventions that aimed to change these constructs and quantified the magnitude of changes in behavior observed when interventions generated increases in autonomous motivation, perceived competence, or both.MethodComputerized searches and additional strategies identified 67 articles that yielded 135 effect sizes relevant to our research questions. Random effects meta-analyses were conducted via STATA.ResultsInterventions increased autonomous motivation and perceived competence in 31% and 38% of tests, respectively. Increasing autonomous motivation led to a medium change in health behaviors (d+=. 47, 95% CI [. 44,. 83]) and increasing perceived competence generated a small-to-medium change (d+=. 34, 95% CI [. 22,. 47]). Interventions that failed to generate significant improvements in autonomous motivation and perceived competence had much smaller effects on behavior change (d+=. 13 and. 10, respectively). There was little evidence of synergistic effects. Changing both autonomous motivation and perceived competence (d+=. 42) did not lead to a larger effect on behavior compared with changing autonomous motivation on its own (d+=. 61), but had a larger effect compared with changing perceived competence on its own (d+=. 21).ConclusionThe present review suggests that autonomous motivation and perceived competence are valid targets for interventions to promote health behavior change but also indicates that research is warranted to ensure that interventions more effectively engage these targets.
