PURPOSE/OBJECTIVES: To investigate the relationship between anxiety and directed attention (the ability to focus and concentrate) in women awaiting breast cancer surgery and the potential influence of age and extent of anticipated surgery (breast conservation versus mastectomy) on attentional functioning and anxiety.
Descriptive, cross-sectional.
Convenience sample of 45 women newly diagnosed with localized breast cancer at a Midwestern university medical center.
Subjects were assessed approximately 11 days before surgery using objective measures of attention: Digit Span, the Symbol Digit Modalities Test, the Necker Cube Pattern Control Test, the Attentional Function Index (a subjective measure of effectiveness of attentional functioning), and the Tension-Anxiety subscale of the Profile of Mood States.
Capacity to direct attention, perceived attentional functioning, anxiety level, age, and extent of anticipated breast surgery.
Level of anxiety was related inversely (r = -0.63, p < 0.01) to perceptions of attentional functioning but not to performance on any objective measures of attention in the pretreatment period. No differences in anxiety level existed in regard to age or extent of anticipated surgery. However, older women (> or = 55 years) showed overall significantly lowered (p < 0.001) performance on the attentional measures than younger women.
Preoperative anxiety is a clinically significant issue in women newly diagnosed with breast cancer regardless of age and extent of anticipated surgery. Higher anxiety requires use of attentional resources and initially may act to reduce perceptions of effectiveness in attentional functioning. Older women who have high anxiety combined with both subjective and objective decline in attentional functioning may be at particularly high risk for attentional fatigue.
Women newly diagnosed with breast cancer may experience not only increased anxiety and associated perceptions of decreased attentional functioning but also a subsequent depletion of attentional reserves as a result of the onset of attentional fatigue. Nurses can assess anxiety in women during the preoperative period and assist them in coping with the psychological and cognitive demands associated with this highly stressful period.
目的/目标:探讨等待乳腺癌手术的女性中焦虑与定向注意力(集中和专注的能力)之间的关系,以及年龄和预期手术范围(保乳手术与乳房切除术)对注意力功能和焦虑的潜在影响。
描述性横断面研究。
来自中西部一所大学医学中心的45名新诊断为局限性乳腺癌的女性组成的便利样本。
在手术前约11天对受试者进行评估,使用注意力的客观测量方法:数字广度、符号数字模式测验、内克尔立方体图案控制测验、注意力功能指数(注意力功能有效性的主观测量)以及情绪状态剖面图中的紧张-焦虑分量表。
定向注意力能力、感知到的注意力功能、焦虑水平、年龄以及预期乳房手术范围。
焦虑水平与注意力功能的感知呈负相关(r = -0.63,p < 0.01),但与术前任何注意力客观测量指标的表现无关。在年龄或预期手术范围方面,焦虑水平没有差异。然而,年龄较大的女性(≥55岁)在注意力测量指标上的总体表现明显低于年轻女性(p < 0.001)。
术前焦虑是新诊断为乳腺癌的女性中一个具有临床意义的问题,无论年龄和预期手术范围如何。较高的焦虑需要消耗注意力资源,最初可能会降低对注意力功能有效性的感知。焦虑程度高且注意力功能在主观和客观上均下降的老年女性可能特别容易出现注意力疲劳。
新诊断为乳腺癌的女性不仅可能会经历焦虑增加以及随之而来的注意力功能下降的感知,还可能由于注意力疲劳的出现而导致注意力储备随后耗尽。护士可以在术前评估女性的焦虑情况,并帮助她们应对与这个高度紧张时期相关的心理和认知需求。
