Abstract

Objectives: Insomnia is associated with mental ill health, worry and rumination-the two latter contribute to pre-sleep cognitive arousal. These variables also associate with psychological inflexibility, including cognitive fusion (CF), a literal attachment to unhelpful thoughts, patterns and rules. Good sleepers generally have low CF, good sleep hygiene and a belief in sleep control, but individuals high in CF may have unhelpful beliefs about sleep hygiene and sleep control.

Methods: We investigated associations between CF, sleep hygiene and sleep control, hypothesizing that each would contribute significant variance to insomnia and mediate the relationship between CF and insomnia.

Results: Participants were 411 adults (M_age = 45.9 years, SD = 15.6) completing an online survey including demographics, and questionnaires about insomnia (ISI), CF (CFQ), sleep hygiene (SHS) and sleep control (BRISC). Hierarchical regression accounted for 34% of variance in insomnia (p < .001), showing that after controlling for demographic variables, CF, sleep hygiene and sleep control each accounted for significant variance in insomnia, with sleep control the strongest predictor (β = -.304). Parallel mediation modelling accounting for 22.2% of variance in insomnia (p < .001) showed both sleep hygiene and sleep control partially mediated the CF and insomnia relationship.

Conclusions: Our study shows for the first time that CF, sleep hygiene and sleep control beliefs are inter-related in their impact on insomnia. As CF is a core component of psychological inflexibility, ACT plus behaviour therapy (ACT-I) may be a more suitable insomnia intervention than CBT plus behaviour therapy (CBT-I) for some people.

睡眠卫生和睡眠控制在认知融合与失眠严重程度之间起中介作用。

目的：失眠与精神疾病、担忧和沉思有关，后两者有助于睡眠前的认知唤醒。这些变量还与心理上的不灵活性有关，包括认知融合（CF），即对无益的想法、模式和规则的字面依恋。睡眠质量好的人通常有较低的CF、良好的睡眠卫生和对睡眠控制的信念，但CF高的人可能对睡眠卫生和睡眠控制有无益的信念。方法：我们调查了CF、睡眠卫生和睡眠控制之间的关系，假设每个因素都对失眠有显著的影响，并在CF和失眠之间起到中介作用。结果：411名成年人（年龄45.9岁，SD = 15.6）完成了一项在线调查，包括人口统计学、失眠（ISI）、CF （CFQ）、睡眠卫生（SHS）和睡眠控制（BRISC）问卷。结论：我们的研究首次表明，CF、睡眠卫生和睡眠控制信念在影响失眠方面是相互关联的。由于CF是心理不灵活性的核心组成部分，对于某些人来说，ACT +行为治疗（ACT- i）可能比CBT +行为治疗（CBT- i）更适合失眠干预。
