Body-focused repetitive behaviors (BFRBs) are repeated actions to one’s body resulting in physical damage. Limited research has examined sleep, a known factor in psychological health, within the context of pediatric BFRBs. The current study sought to explore the connection between disordered sleep and BFRBs in a community sample. Aim 1 of the study was to determine the predictive power of group membership [control group (no BFRB symptoms reported), subthreshold BFRB group (mild BFRB symptoms reported; severity score of 2 or less out of 9), and those with symptoms characteristic of BFRBs (more than mild BFRB symptoms reported; severity score of 3 or higher out of 9)] for level of sleep disturbance. A hierarchical regression revealed that there was a significant effect of group membership after controlling for anxiety (F (3, 410) = 152.976, p < .001). Aim 2 of the study was to test whether there was a relationship between sleep disturbance and BFRB severity. The hierarchical regression revealed that at Step 1, anxiety accounted for 23.1% of the variance in BFRB severity (β = 0.48, t = 8.87, p < 0.001). At Step 2, sleep disturbance total score accounted for an additional 7.2% of the variance, suggesting this variable makes a unique contribution to overall BFRB severity (SDSC: β = 0.40, t = 5.18, p < 0.001). The findings of this study suggest that sleep could be a clinical factor to consider when conceptualizing a child with BFRBs.

以身体为中心的重复行为（BFRB）是对身体的重复动作，导致身体损伤。在儿科 BFRB 的背景下，对睡眠这一已知的心理健康因素进行了有限的研究。当前的研究旨在探索社区样本中睡眠障碍与 BFRB 之间的联系。该研究的目的 1 是确定组成员的预测能力[对照组（未报告 BFRB 症状）、阈下 BFRB 组（报告轻度 BFRB 症状；严重程度评分为 2 分或以下（满分 9 分））以及具有以下症状特征的组： BFRB（报告的轻度 BFRB 症状以上；严重程度评分为 3 分或更高（满分 9 分））] 睡眠障碍水平。分层回归显示，在控制焦虑后，群体成员资格具有显着影响 (F (3, 410) = 152.976，p < .001）。该研究的目的 2 是测试睡眠障碍与 BFRB 严重程度之间是否存在关系。层次回归显示，在第 1 步，焦虑占 BFRB 严重程度方差的 23.1%（β = 0.48，t = 8.87，p  < 0.001）。在第 2 步，睡眠障碍总分占方差的额外 7.2%，表明该变量对整体 BFRB 严重程度具有独特的贡献（SDSC：β = 0.40，t = 5.18，p < 0.001 ）  。这项研究的结果表明，在概念化患有 BFRB 的儿童时，睡眠可能是一个需要考虑的临床因素。
