While self-efficacy is known to play an important role in music performance, the magnitudes of reported effect sizes are inconsistent. The purpose of this meta-analysis was to estimate the population effect size for (a) the relationship between self-efficacy and achievement, (b) the relationship between self-efficacy and music performance anxiety (MPA), and (c) the influence of self-efficacy interventions. A literature search identified 220 self-efficacy studies with 46 meeting the inclusion criteria. Heterogeneity among findings required the use of a random-effects model. The results revealed a medium positive effect size between self-efficacy and achievement. Moderator analysis based on age identified a significant difference between secondary school and collegiate participants, while a comparison of instrumentalists and vocalists failed to reject the null. The relationship between self-efficacy and MPA exhibited a medium negative effect size with a significant difference between secondary school and collegiate participants. Self-efficacy interventions demonstrated a substantial impact on self-efficacy beliefs. Multiple contrasts identified differences in intervention effectiveness between K-12, collegiate, and older adult participants. The absence of vocal studies limited comparisons between instrumentalists and vocalists. This study establishes benchmarks for understanding self-efficacy’s role in music performance and makes recommendations for future research to improve achievement and the well-being of musicians.

自我效能与音乐表演：荟萃分析

虽然众所周知，自我效能在音乐表演中发挥着重要作用，但报告的效果大小并不一致。本荟萃分析的目的是估计（a）自我效能与成就之间的关系、（b）自我效能与音乐表演焦虑（MPA）之间的关系以及（c）影响的群体效应大小。的自我效能干预。文献检索确定了 220 项自我效能研究，其中 46 项符合纳入标准。研究结果之间的异质性需要使用随机效应模型。结果显示，自我效能和成就之间存在中等程度的正效应。基于年龄的主持人分析发现中学和大学参与者之间存在显着差异，而乐器演奏家和歌手的比较未能拒绝零。自我效能感与 MPA 之间的关系表现出中等程度的负面影响，在中学和大学参与者之间存在显着差异。自我效能干预显示出对自我效能信念的重大影响。多重对比发现了 K-12、大学和老年人参与者之间干预效果的差异。声乐研究的缺乏限制了器乐家和声乐家之间的比较。这项研究为理解自我效能在音乐表演中的作用建立了基准，并为未来提高音乐家的成就和福祉的研究提出了建议。
