目的 调查乳腺癌患者配偶夫妻疾病沟通现状及其影响因素，为临床开展针对性配偶或夫妻干预提供参考。方法 采用一般资料问卷、夫妻癌症沟通问题量表配偶部分、二元应对量表、洛克-华莱氏婚姻调适量表及癌症自我效能量表-配偶版对278名中青年乳腺癌患者配偶进行调查。结果 中青年乳腺癌患者配偶的夫妻疾病沟通问题总分为15.66±2.27，自我效能、二元应对、婚龄及累计照顾时长是中青年乳腺癌患者配偶夫妻疾病沟通问题的影响因素（均P<0.05），可解释总变异的40.1%。结论 中青年乳腺癌患者配偶夫妻疾病沟通问题处于中等偏低水平，自我效能低、二元应对水平低、婚龄短及累计照顾时间短的配偶与患者间更易出现沟通问题。医护人员应重视婚龄短、照护时间较短的夫妻，可以自我效能及二元应对为切入点制订配偶及夫妻相关护理措施，改善夫妻疾病沟通问题。
Objective To probe into the current situation and influencing factors of cancer-related communication problems from the perspective of spouses of young and middle-aged breast cancer patients, and to provide references for formulation of clinical intervention programs for spouses or couples. Methods Totally, 278 spouses of young and middle-aged breast cancer patients were surveyed by using the general information questionnaire, the Cancer-Related Communication Problems Scale for spouse, the Dyadic Coping Inventory, the Locke-Wallace Short Marital Adjustment and the Cancer Self-Efficacy Scale-Spouse. Results The spouses scored (15.66±2.27) points in cancer-related communication problems. Spouse self-efficacy, dyadic coping, years of marriage and cumulative time in caregiving were influencing factors of spouses′ cancer-related communication problems level （all P<0.05）, altogether explaining 40.1% of the total variation. Conclusion Spouses of young and middle-aged breast cancer couples had slightly-below-medium level of cancer-related communication problems. The spouses with low self-efficacy, low dyadic coping level, shorter years of marriage and shorter cumulative time in caregiving are more likely to have communication problems with patients. Medical staff should pay attention of spouses with shorter years of marriage and shorter cumulative time in caregiving, take self-efficacy and dyadic coping as the breakthrough point, and formulate relevant nursing measures for spouses or couples, so as to improve cancer-related communication between couples.
