Whether resilience should be conceptualised as a state or trait is debated. The precise distinction between state versus trait aspects of resilience can help identify dynamic targets for resilience-based intervention trials involving cancer patients. This study was designed to disentangle the state and trait components of resilience in patients with breast cancer with the help of Generalisability Theory (GT) methods.
The relative contributions of state (temporary) and trait (enduring) aspects of resilience were calculated using a 10-item Resilience Scale Specific to Cancer (RS-SC-10) and GT methods. In all, 391 patients were enrolled from the 'Be Resilient to Breast Cancer ' (BRBC) trial, and data from 317 patients (81.7%) were collected at baseline, 3 months, 6 months, and 12 months after the intervention.
The subscale of Generic Elements demonstrated high generalisability value (relative G-coefficient = 0.81) across different occasions and captured 79% of the variance attributed to enduring aspects of resilience. The subscale of Shift-Persist showed low generalisability value (relative G-coefficient = 0.31) and identified 59% of the variance attributed to temporary aspects of resilience. The GT studies suggested that 5-7 items per scale and three measurement occasions were adequate for score reliability evaluation.
Resilience should be conceptualised as a state-trait mixed psychological variable in breast cancer patients. The subscale of Shift-Persist in RS-SC-10 is amenable to intervention and could be utilised as a primary outcome in resilience-based intervention trials.
None.
复原力应被概念化为一种状态还是特质存在争议。复原力的状态与特质方面的精确区分有助于确定针对癌症患者的基于复原力的干预试验的动态目标。本研究旨在借助概化理论（GT）方法厘清乳腺癌患者复原力的状态和特质成分。
使用10项癌症特异性复原力量表（RS-SC-10）和GT方法计算复原力的状态（暂时的）和特质（持久的）方面的相对贡献。总共从“对乳腺癌保持复原力”（BRBC）试验中招募了391名患者，并在干预后的基线、3个月、6个月和12个月收集了317名患者（81.7%）的数据。
通用要素子量表在不同场合显示出较高的概化值（相对G系数 = 0.81），并捕获了归因于复原力持久方面的79%的方差。转变-坚持子量表显示出较低的概化值（相对G系数 = 0.31），并识别出归因于复原力暂时方面的59%的方差。GT研究表明，每个量表5 - 7个项目和三个测量场合足以进行分数可靠性评估。
在乳腺癌患者中，复原力应被概念化为一种状态-特质混合的心理变量。RS-SC-10中的转变-坚持子量表适合进行干预，可作为基于复原力的干预试验的主要结局。
无。
