背景：睡眠障碍是为患有阿尔茨海默病（AD）的亲人提供护理的常见后果。我们探讨了有用的愉快事件和活动限制（PEAR）模型预测多个领域的sleep disturbance.Methods：我们的样本包括125配偶AD照顾者。参与者完成了匹兹堡睡眠质量指数（PSQI），并询问了他们参与愉快活动的频率以及他们在过去一个月内参与社交和娱乐活动时感到受到限制的程度。参与者被分为三组之一：HPLR =高愉悦事件+低活动限制（=参考组; N = 38）; HPHR/LPLR =高愉悦事件+高活动限制或低愉悦事件+低活动限制（N = 52）; LPHR：低愉悦事件+高活动限制（N = 35）。这三个组进行了比较的7个分量表的PSQI.Results：显着差异被发现之间的主观睡眠质量，睡眠潜伏期，习惯性睡眠效率，睡眠障碍，白天功能障碍的措施HPLR和LPHR组。此外，HPLR和HPHR/LPLR组之间的主观睡眠质量，睡眠潜伏期，和习惯性睡眠效率的显着差异，和HPHR/LPLR和LPHR组之间的睡眠障碍和白天dysfunctions.Conclusions：这项研究提供了广泛的支持PEAR模型，并表明，干预措施的重点是行为激活可能会提供好处，非情感领域，包括睡眠。
Background: Sleep disturbance is a common consequence of providing care to a loved one with Alzheimer's disease (AD). We explored the usefulness of the Pleasant Events and Activity Restriction (PEAR) model for predicting multiple domains of sleep disturbance.Methods: Our sample consisted of 125 spousal AD caregivers. Participants completed the Pittsburg Sleep Quality Index (PSQI) and were questioned regarding the frequency with which they engaged in pleasant events and the extent to which they felt restricted in engaging in social and recreational activities in the past month. Participants were classified into one of three groups: HPLR = High Pleasant Events + Low Activity Restriction (= reference group; N = 38); HPHR/LPLR = either High Pleasant Events + High Activity Restriction or Low Pleasant Events + Low Activity Restriction (N = 52); and LPHR: Low Pleasant Events + High Activity Restriction (N = 35). These three groups were compared on the seven subscales of the PSQI.Results: Significant differences were found between the HPLR and LPHR groups on measures of subjective sleep quality, sleep latency, habitual sleep efficiency, sleep disturbance, and daytime dysfunction. Additionally, significant differences were found between the HPLR and HPHR/LPLR groups on subjective sleep quality, sleep latency, and habitual sleep efficiency, and between the HPHR/LPLR and LPHR groups on sleep disturbance and daytime dysfunction.Conclusions: This study provides broad support for the PEAR model and suggests that interventions focusing on behavioral activation may potentially provide benefits to non-affective domains including sleep.
