While the Brief Coping Orientation to Problems Experienced (Brief COPE) is widely used in clinical and nonclinical populations, the reliability of its subscales is uncertain. This study aimed to establish and improve the construct validity and reliability of the Brief COPE in a cohort of Australian rehabilitation health professionals.
343 rehabilitation health professionals completed the Brief COPE and a demographic questionnaire in an anonymous online survey. Principal components analysis was performed to identify the number of factors in the Brief COPE. Factors were interpreted against the theoretical constructs intended to underlie the instrument. Items loading on separate factors then underwent reliability analysis to determine internal consistency of subscales.
Principal components analysis identified two dimensions (task-focused coping and distraction-focused coping) in a modified version of the Brief COPE, with appropriate construct validity and a high level of reliability (Cronbach's alpha: 0.72 to 0.82). The two dimensions were distinct from each other and accounted for over 50% of variance between items.
The modified Brief COPE scale is consistent with existing theories of coping, has demonstrated acceptable reliability and construct validity in a cohort of health professionals, and is appropriate for use in future studies of similar populations.
虽然经验性问题应对取向简短量表（Brief COPE）在临床和非临床人群中得到广泛应用，但它的子量表的可靠性尚不确定。本研究旨在为澳大利亚康复卫生专业人员队列建立和提高Brief COPE 的结构效度和信度。
343 名康复卫生专业人员在匿名在线调查中完成了Brief COPE 和人口统计学问卷。主成分分析用于确定Brief COPE 中的因子数量。根据旨在作为仪器基础的理论结构来解释因子。然后对单独因子上的项目进行可靠性分析，以确定子量表的内部一致性。
主成分分析在Brief COPE 的修改版本中确定了两个维度（任务导向应对和分心导向应对），具有适当的结构效度和较高的信度（克朗巴赫的 alpha：0.72 到 0.82）。这两个维度彼此不同，占项目之间差异的 50%以上。
修改后的Brief COPE 量表与现有的应对理论一致，在卫生专业人员队列中表现出可接受的信度和结构效度，适用于类似人群的未来研究。
