Studies have found that sleep disturbance is associated with obsessive-compulsive symptoms. This study aimed to elaborate on the mediating and moderating mechanisms between these two variables. We hypothesized that repetitive negative thinking plays a mediating role in the relationship between sleep disturbance and obsessive-compulsive symptoms, and experiential avoidance plays a moderating role.
This study included 639 Chinese adults. A questionnaire survey was used to assess sleep quality, obsessive-compulsive symptoms, experiential avoidance, repetitive negative thinking, and depression symptoms. A moderated mediation model was established.
After controlling for depressive symptoms, repetitive negative thinking partially mediated the positive correlation between sleep disturbance and obsessive-compulsive symptoms. This indirect relationship was significant in individuals with lower experiential avoidance levels. Particularly, the relationship between sleep disturbance and repetitive negative thinking was significant among individuals with lower experiential avoidance levels, but not among individuals with higher experiential avoidance levels.
This study demonstrated that repetitive negative thinking partially mediated the impact of sleep disturbance on obsessive-compulsive symptoms. The findings suggest that when providing support to individuals with sleep disturbance and obsessive-compulsive symptoms, assessing their level of experiential avoidance is necessary for performing targeted interventions. Individuals with low experiential avoidance may benefit from a clinical intervention targeting repetitive negative thinking to improve sleep quality and obsessive-compulsive symptoms.
研究发现睡眠障碍与强迫症状有关。本研究旨在阐述这两个变量之间的中介和调节机制。我们假设重复消极思维在睡眠障碍与强迫症状的关系中起中介作用，而经验性回避起调节作用。
本研究纳入639名中国成年人。采用问卷调查法评估睡眠质量、强迫症状、经验性回避、重复消极思维和抑郁症状。建立了一个有调节的中介模型。
在控制抑郁症状后，重复消极思维部分中介了睡眠障碍与强迫症状之间的正相关。这种间接关系在经验性回避水平较低的个体中显著。特别是，睡眠障碍与重复消极思维之间的关系在经验性回避水平较低的个体中显著，但在经验性回避水平较高的个体中不显著。
本研究表明重复消极思维部分中介了睡眠障碍对强迫症状的影响。研究结果表明，在为有睡眠障碍和强迫症状的个体提供支持时，评估他们的经验性回避水平对于进行有针对性的干预是必要的。经验性回避水平低的个体可能受益于针对重复消极思维的临床干预，以改善睡眠质量和强迫症状。
