Our aim was to determine if insomnia severity, dysfunctional beliefs about sleep, and depression predicted sleep-related safety behaviors.
Standard sleep-related measures (such as the Insomnia Severity Index; the Dysfunctional Beliefs About Sleep scale; the Depression, Anxiety, and Stress Scale; and the Sleep-Related Behaviors Questionnaire) were administered. Additionally, 14 days of sleep diary (Pittsburg Sleep Diary) data and actual use of sleep-related behaviors were collected.
Regression analysis revealed that dysfunctional beliefs about sleep predicted sleep-related safety behaviors. Insomnia severity did not predict sleep-related safety behaviors. Depression accounted for the greatest amount of unique variance in the prediction of safety behaviors, followed by dysfunctional beliefs. Exploratory analysis revealed that participants with higher levels of depression used more sleep-related behaviors and reported greater dysfunctional beliefs about their sleep.
The findings underlie the significant influence that dysfunctional beliefs have on individuals' behaviors. Moreover, the results suggest that depression may need to be considered as an explicit component of cognitive-behavioral models of insomnia.
我们的目的是确定失眠严重程度、对睡眠的功能失调信念以及抑郁是否能预测与睡眠相关的安全行为。
采用标准的与睡眠相关的测量方法（如失眠严重程度指数、对睡眠的功能失调信念量表、抑郁、焦虑和压力量表以及与睡眠相关行为问卷）。此外，收集了14天的睡眠日记（匹兹堡睡眠日记）数据以及与睡眠相关行为的实际使用情况。
回归分析显示，对睡眠的功能失调信念可预测与睡眠相关的安全行为。失眠严重程度不能预测与睡眠相关的安全行为。在安全行为预测方面，抑郁解释的独特方差量最大，其次是功能失调信念。探索性分析表明，抑郁水平较高的参与者使用更多与睡眠相关的行为，并报告对自己睡眠的功能失调信念更强。
这些发现凸显了功能失调信念对个体行为的重大影响。此外，结果表明抑郁可能需要被视为失眠认知行为模型的一个明确组成部分。
