摘要目的:了解中青年女性乳腺癌患者根治术后放化疗期间失志症候群现状，分析其影响因素。方法:采用便利抽样方法，选取2019年1—9月在吉林省某三级甲等医院乳腺外科的中青年女性乳腺癌患者204例为研究对象。采用一般情况调查表、中文版失志量表（Demoralization Scale-Mandarin Version，DS-MV）、医学应对量表（Medical Coping Modes Questionnaire，MCMQ）、社会支持评定量表（Social Support Rate Scale，SSRS）对其进行调查。共发放问卷204份，回收有效问卷192份。结果:192例中青年女性乳腺癌患者DS-MV得分（33.72±14.23）分；MCMQ总分（42.49±8.83）分，其中面对应对（19.12±4.10）分，回避应对（14.28±3.26）分，屈服应对（9.39±3.48）分；SSRS总分（35.39±6.23）分。多重线性回归分析显示，年龄、文化程度、术后时间、面对应对、屈服应对、社会支持是乳腺癌患者失志的影响因素。结论:中青年乳腺癌患者根治术后放化疗期间失志处于较高水平。医护人员针对年龄较小、文化水平低、术后时间短、采取屈服应对方式面对疾病，且社会支持较低的患者，应给予针对性干预，促进其身心健康。
