This longitudinal study investigated pre-screening factors that predicted breast cancer-specific distress among 1286 women who were undergoing annual mammography screening as part of a UK programme for younger women (i.e., under 50) with a family history of breast cancer.
Women completed questionnaires one month prior to screening, and one and six months after receiving screening results. Factors measured were breast cancer worry, perceived risk, cognitive appraisals, coping, dispositional optimism, and background variables relating to screening history and family history.
Pre-screening cancer worry was the most important predictor of subsequent worry, explaining 56/61% and 54/57% of the variance at one and six months follow-up, respectively. Other salient pre-screening predictors included high perceived risk of breast cancer, appraisals of high relevance and threat associated with the family history, and low perceived ability to cope emotionally. Women who had previously been part of the screening programme and those with a relative who had recently died from breast cancer were also vulnerable to longer-term distress. A false positive screening result, pessimistic personality, and coping efforts relating to religion and substance use predicted outcomes of screening at one month follow-up, but were not predictive in the longer-term.
Early intervention to ameliorate high levels of cancer-related distress and negative appraisals would benefit some women as they progress through the familial breast screening programme.
这项纵向研究调查了在英国一项针对有乳腺癌家族史的年轻女性(即50岁以下)的年度乳房X线筛查项目中,1286名接受筛查的女性中预测乳腺癌特异性困扰的预筛查因素。
女性在筛查前一个月、收到筛查结果后1个月和6个月完成问卷调查。测量的因素包括乳腺癌担忧、感知风险、认知评估、应对方式、性格乐观程度,以及与筛查史和家族史相关的背景变量。
筛查前的癌症担忧是后续担忧的最重要预测因素,分别解释了随访1个月和6个月时56/61%和54/57%的变异。其他显著的预筛查预测因素包括对乳腺癌的高感知风险、对与家族史相关的高度相关性和威胁的评估,以及情绪应对能力低。之前参加过筛查项目的女性以及有亲属最近死于乳腺癌的女性也更容易长期困扰。假阳性筛查结果、悲观性格以及与宗教和物质使用相关的应对努力可预测随访1个月时的筛查结果,但从长期来看并无预测作用。
在一些女性参与家族性乳房筛查项目的过程中,早期干预以减轻与癌症相关的高度困扰和负面评估将使她们受益。
