目的 探讨积极应对方式在乳腺癌术后患者自我效能感与恐动症间的中介作用。 方法 采用便利抽样法于2021年12月至2022年7月选取新疆乌鲁木齐市某三级甲等医院乳腺外科的246例患者为研究对象，应用一般资料调查问卷、恐动症评分表、乳腺癌幸存者自我效能感量表和简易应对方式问卷对其进行调查，并分析积极应对方式、自我效能感与恐动症三者间的关系。 结果 乳腺癌术后患者积极应对方式、自我效能感与恐动症之间存在相关性（P＜0.01）。自我效能感对恐动症的总效应为-0.372（95%CI=-0.461~-0.284），直接效应为-0.205（95%CI=-0.282~-0.128)，间接效应为-0.167（95%CI=-0.246~-0.105），中介效应占比45.16%。 结论 自我效能感可通过积极应对方式间接影响恐动症，医护人员应提升乳腺癌术后患者的自我效能感，鼓励患者采取积极的应对方式，进而降低患者的恐动水平。
