Abstract

Body-focused repetitive behaviors (BFRBs) are recurrent behaviors targeting one or more body regions that may associate with negative outcomes. Little is known on their prevalence and correlates in psychiatric populations. This study examined the preliminary prevalence and correlates of BFRBs in 67 youth aged 9–17 years with primary anxiety-related disorders, mood disorders, or attention deficit and hyperactivity disorder (ADHD), using the Repetitive Body-focused Behavior Scale (RBBS), the Clinical Global Impressions scale, and the Behavior Assessment System for Children—2nd Edition, Behavioral & Emotional Screening System (BASC-2-BESS). Nearly half of the youth and parents reported significant child BFRBs on the RBBS. Additionally, 15% of the youth and 4.5% of the parents reported significant child distress/impairment related to BFRBs. A primary diagnosis of ADHD associated with greater parent-reported BFRB rates, number, and severity. An increased proportion of girls vs. boys presented with child-reported BFRBs and associated distress/impairment. The presence of BFRBs across the sample was associated with increased internalizing and externalizing symptom severity as measured with the BASC-2-BESS. In addition, internalizing and externalizing symptom severity positively correlated with BFRB severity. Our results suggest youth with psychiatric conditions, especially ADHD, who present with elevated symptom severity, may be particularly at-risk for concomitant BFRBs.

摘要

以身体为中心的重复行为（BFRB）是针对一个或多个可能与负面结果相关的身体部位的复发行为。关于它们的流行及其在精神病人群中的相关性知之甚少。这项研究使用重复性的以身体为中心的行为量表（RBBS），研究了67名9-17岁年龄段患有原发性焦虑相关疾病，情绪障碍或注意力不足和多动障碍（ADHD）的年轻人中BFRBs的初步患病率及其相关性，临床全球印象量表和儿童行为评估系统-第二版，行为与情感筛查系统（BASC-2-BESS）。近一半的青年和父母在RBBS上报告有大量的儿童BFRB。此外，15％的年轻人和4.5％的父母报告说与BFRB相关的严重儿童困扰/损害。父母报告的BFRB发生率，数量和严重性增加与ADHD的初步诊断有关。出现儿童报告的BFRB和相关的困扰/损害的女孩与男孩的比例增加。如通过BASC-2-BESS测量，整个样品中BFRB的存在与内在和外在症状的严重程度增加相关。此外，内化和外化症状严重程度与BFRB严重程度呈正相关。我们的结果表明，患有精神疾病的青年，尤其是多动症，其症状严重程度升高，可能尤其伴有BFRB。如通过BASC-2-BESS测量，整个样品中BFRB的存在与内在和外在症状的严重程度增加相关。此外，内化和外化症状严重程度与BFRB严重程度呈正相关。我们的结果表明，患有精神疾病的青年，尤其是多动症，其症状严重程度升高，可能尤其伴有BFRB。如通过BASC-2-BESS测量，整个样品中BFRB的存在与内在和外在症状的严重程度增加相关。此外，内化和外化症状严重程度与BFRB严重程度呈正相关。我们的结果表明，患有精神疾病的青年，尤其是多动症，其症状严重程度升高，可能尤其伴有BFRB。
