以身体为中心的重复性行为（bfrb），包括拔头发、咬指甲和抠皮肤，本质上是重复的、习惯性的和强迫性的。虽然是拔毛癖和抠皮障碍等疾病的特征，但bfrb也与其他精神疾病有关。迄今为止，研究未能利用跨诊断方法检查与bfrb有关的神经认知风险因素，特别是执行功能。本研究从一个较大的年轻人样本中招募了53名参与者（n = 27名表现出bfrb， n = 26名随机选择的对照组）。参与者完成了一组自动神经认知测试，包括认知灵活性、工作记忆、计划和组织等任务。结果显示，BFRB组参与者的认知灵活性明显低于对照组（d = 0.63）。在其他神经认知领域没有发现差异。然而，计划和组织显示了与各种BFRB严重性措施的重要关系。讨论了进一步研究的意义、局限性和途径。
Body-focused repetitive behaviors (BFRBs), including hair pulling, nail biting, and skin picking are repetitive, habitual, and compulsive in nature. Although characteristic of disorders such as trichotillomania and skin picking disorder, BFRBs are associated with other psychiatric conditions as well. To date, research has failed to examine neurocognitive risk factors, particularly executive functioning, implicated in BFRBs utilizing a transdiagnostic approach. The present study recruited 53 participants (n = 27 demonstrating BFRBs and n = 26 randomly selected controls) from a larger sample of young adults. Participants completed an automated neurocognitive test battery including tasks of cognitive flexibility, working memory, and planning and organization. Results revealed that participants in the BFRB group demonstrated significantly poorer cognitive flexibility (d = 0.63) than controls. No differences were noted in other neurocognitive domains. However, planning and organization demonstrated a significant relationship with various BFRB severity measures. Implications, limitations, and avenues for further research are discussed.
