目的：本研究旨在探讨乳腺癌患者的疾病认知和应对策略在多大程度上解释诊断时和诊断后6个月的心理困扰（相对于人口统计学和疾病相关变量）。方法：女性在诊断后不久被招募到研究中。共有90名妇女在时间1完成了研究材料（疾病感知问卷-修订，癌症应对问卷和医院焦虑和抑郁量表）。大约6个月后，同样的问卷被发送给那些在第一次同意的人，72名女性将填好的问卷交回。结果：聚类分析用于确定报告疾病感知分数相似概况的应答者群体。回归分析表明，在诊断时和诊断后6个月，其中一组比另一组更有可能经历心理困扰。疾病知觉集群成员和积极焦点型应对是诊断时和诊断后6个月较低心理困扰的最重要和最一致的预测因子。结论：在研究期间，疾病认知保持相对稳定，因此我们无法阐明疾病认知的变化是否与心理症状的相应变化相关。未来的研究应该评估专门设计用于改变乳腺癌妇女疾病认知的干预措施对心理困扰的影响。版权所有：John Wiley & Sons， Ltd
Objective: This study aimed to examine the extent to which illness perceptions and coping strategies among women diagnosed with breast cancer explain psychological distress at diagnosis and at 6 months post diagnosis relative to demographic and illness-related variables.Methods: Women were recruited to the study shortly after diagnosis. A total of 90 women completed study materials (Illness Perception Questionnaire-Revised, the Cancer Coping Questionnaire and the Hospital Anxiety and Depression Scale) at time 1. The same questionnaires were sent approximately 6 months later to those who had consented at time 1, and completed questionnaires were returned by 72 women.Results: Cluster analysis was used to identify groups of respondents who reported a similar profile of illness perception scores. Regression analysis demonstrated that one of these clusters was more likely to experience psychological distress than the other both at diagnosis and at 6 months post diagnosis. Illness perception cluster membership and positive focus type coping were the most important and consistent predictors of lower psychological distress at diagnosis and at 6 months post diagnosis.Conclusions: Illness perceptions remained relatively stable over the study period, and therefore we are unable to clarify whether changes in illness cognitions are associated with a corresponding change in psychological symptoms. Future research should evaluate the impact on psychological distress of interventions specifically designed to modify illness cognitions among women with breast cancer.
