BACKGROUND Resilience is a psychological construct referring to one's positive adaptation in response to adversity. Evidence suggests that resilience may contribute to various function domains in adults with chronic physical disabilities. PURPOSE To test hypothesized temporal associations between resilience and four function domains (anxiety, depression, social role satisfaction, and physical function) in individuals with chronic physical disabilities. METHODS Participants were 1,574 adults with one of four chronic physical disabilities (spinal cord injury, muscular dystrophy, multiple sclerosis, or postpolio myelitis syndrome) who were participating in a large, ongoing USA-based longitudinal survey study. Three surveys were mailed on an approximately yearly basis. Resilience was assessed using the Connor-Davidson Resilience Scale 10-item (CDRSC-10) and each function domain was assessed using the respective Patient Reported Outcome Measurement System (PROMIS) short-form. RESULTS Cross-lagged path models evidenced statistically significant reciprocal relationships between resilience and each function domain except physical function. The standardized lagged coefficients corresponding to resilience predicting social role satisfaction (T1-T2 = 0.09, T2-T3 = 0.09) had similar effect sizes as those corresponding to social role satisfaction predicting resilience (T1-T2 = 0.11, T2-T3 = 0.04), although resilience was a slightly stronger predictor in the second lag. In models assessing psychological function, resilience was a stronger predictor of later psychological function (resilience-to-anxiety, T1-T2 = -0.15, T2-T3 = -0.11; resilience-to-depression, T1-T2 = -0.21, T2-T3 = -0.13) than the inverse (anxiety-to-resilience, T1-T2 = -0.11, T2-T3 = -0.06; depression-to-resilience, T1-T2 = -0.12, T2-T3 = -0.05). CONCLUSIONS The study findings suggest that resilience is a significant prospective predictor of psychological and social function over time in individuals with chronic physical disabilities.

患有慢性身体残疾的成年人的弹性和功能：交叉滞后的面板设计。

背景技术复原力是一种心理构造，指的是人对逆境的积极适应。有证据表明，复原力可能有助于慢性肢体残疾成年人的各种功能领域。目的测试慢性肢体残障人士的弹性与四个功能域（焦虑，抑郁，社会角色满意度和身体功能）之间的假想时间关联。方法参加者是1,574名患有四种慢性身体残疾（脊髓损伤，肌营养不良，多发性硬化症或脊髓灰质炎后综合症）之一的成年人，他们正在进行一项正在进行的，基于美国的大型纵向调查研究。大约每年寄出三份调查问卷。使用Connor-Davidson复原量表10项（CDRSC-10）评估复原力，并使用相应的患者报告结果测量系统（PROMIS）简短形式评估每个功能域。结果交叉滞后路径模型证明了弹性与除身体功能以外的每个功能域之间的统计学显着倒数关系。对应于预测社会角色满意度的弹性的标准化滞后系数（T1-T2 = 0.09，T2-T3 = 0.09）具有与对应于预测社会角色满意度的弹性的系数相似的大小（T1-T2 = 0.11，T2-T3 = 0.04） ，尽管弹性在第二次滞后中的预测力稍强。在评估心理功能的模型中，弹性是以后心理功能的更强预测因子（弹性抗焦虑，T1-T2 = -0.15，T2-T3 = -0.11; 抗抑郁能力，T1-T2 = -0.21，T2-T3 = -0.13），反之（焦虑抗力，T1-T2 = -0.11，T2-T3 = -0.06；抗抑郁能力， T1-T2 = -0.12，T2-T3 = -0.05）。结论研究结果表明，随着时间的流逝，弹性是慢性肢体残疾患者心理和社会功能的重要预测指标。
