目的慢性压力可能是失语症患者的一种常见经历。重要的是，据报道，慢性压力改变了神经网络中心的学习和记忆失语症康复的基本成分。在我们探索慢性压力对康复结果的影响之前，我们必须能够测量这一人群的慢性压力。本研究的目的是（a）修改广泛使用的慢性压力测量（感知压力量表[PSS]; Cohen & Janicki-Deverts，2012）以适应失语症患者（PWA）的沟通需求，以及（B）用PWA验证修改后的PSS（mPSS）。每个参与者都完成了mPSS，测量抑郁，焦虑和弹性，并提供了从头发中提取的压力激素皮质醇样本。皮尔森的积差相关性用于检查mPSS评分与这些指标之间的关联。大约30%的参与者完成了mPSS 1周后，建立重测信度，分析使用的interclass correlation coefficient.ResultsSignificant正相关关系是明显的慢性压力和抑郁症和焦虑症的报告之间。此外，一个显着的负相关关系被发现之间的报告慢性压力和弹性。mPSS还显示了重测信度的证据。没有发现mPSS评分和皮质醇level.ConclusionAlthough问题仍然存在的人与中风后失语症的慢性压力的生物学相关性，慢性压力和几个社会心理变量之间的显着关联提供证据的有效性，这种新兴的措施慢性压力。
PurposeChronic stress is likely a common experience among people with the language impairment of aphasia. Importantly, chronic stress reportedly alters the neural networks central to learning and memory—essential ingredients of aphasia rehabilitation. Before we can explore the influence of chronic stress on rehabilitation outcomes, we must be able to measure chronic stress in this population. The purpose of this study was to (a) modify a widely used measure of chronic stress (Perceived Stress Scale [PSS]; Cohen & Janicki-Deverts, 2012) to fit the communication needs of people with aphasia (PWA) and (b) validate the modified PSS (mPSS) with PWA.MethodFollowing systematic modification of the PSS (with permission), 72 PWA completed the validation portion of the study. Each participant completed the mPSS, measures of depression, anxiety, and resilience, and provided a sample of the stress hormone cortisol extracted from the hair. Pearson's product–moment correlations were used to examine associations between mPSS scores and these measures. Approximately 30% of participants completed the mPSS 1 week later to establish test–retest reliability, analyzed using an interclass correlation coefficient.ResultsSignificant positive correlations were evident between the reports of chronic stress and depression and anxiety. In addition, a significant inverse correlation was found between reports of chronic stress and resilience. The mPSS also showed evidence of test–retest reliability. No association was found between mPSS score and cortisol level.ConclusionAlthough questions remain about the biological correlates of chronic stress in people with poststroke aphasia, significant associations between chronic stress and several psychosocial variables provide evidence of validity of this emerging measure of chronic stress.
