Paediatric Obsessive-Compulsive Disorder (OCD) is associated with significant family accommodation (FA), which frequently results in heightened parental distress, increased OCD severity and impairment. Examining factors which might drive FA is an important focus for the field. This study aimed to examine parents' report of children's emotion regulation (ER) and associations with OCD severity, externalising symptoms, and FA. Participants were 76 youth (7 to 17 years) with a primary diagnosis of OCD and one of their parents. Following child diagnostic and OCD symptom interviews, parents completed study questionnaires. Results indicated that parent-report of children's emotional Lability/Negativity was significantly and positively correlated with child externalising symptoms and FA, whereas children's adaptive ER was significantly and negatively correlated with externalising symptoms only. Furthermore, children's emotional Lability/Negativity predicted externalising symptoms, even when accounting for OCD severity. Lability/Negativity did not predict FA after controlling for OCD severity and externalising symptoms, however it was a significant moderator of the relationship between OCD severity and FA. These findings extend the growing body of literature on ER and OCD in youth and highlight the importance for clinicians to specifically address such deficits in ER as a part of OCD treatment.

小儿强迫症（OCD）与重要的家庭住宿（FA）相关，这通常会导致父母的窘迫感加剧，强迫症的严重程度和损害增加。检查可能驱动FA的因素是该领域的重要重点。本研究旨在检查父母关于儿童情绪调节（ER）的报告以及与强迫症严重程度，外在症状和FA的关系。参加者为76位青年（7至17岁），主要诊断为强迫症，其父母之一。在对孩子进行诊断和强迫症症状采访之后，父母完成了研究问卷。结果表明，父母对儿童情绪低下/负性的报告与儿童外在症状和FA呈显着正相关，而儿童 适应性ER仅与外在症状显着负相关。此外，即使考虑到强迫症的严重性，儿童的情绪不佳/消极情绪也预示着外在症状。在控制强迫症严重程度和外在症状后，不稳定/否定性并不能预测FA，但是，它是强迫症严重程度与FA之间关系的重要调节剂。这些发现扩展了青年时期有关ER和OCD的文献资料，并突出了临床医生作为OCD治疗的一部分，专门解决此类ER不足的重要性。在控制强迫症严重程度和外在症状后，不稳定/否定性并不能预测FA，但是，它是强迫症严重程度与FA之间关系的重要调节剂。这些发现扩展了青年时期有关ER和OCD的文献资料，并突出了临床医生作为OCD治疗的一部分，专门解决此类ER不足的重要性。在控制强迫症严重程度和外在症状后，不稳定性/阴性不能预测FA，但是，它是强迫症严重程度与FA之间关系的重要调节剂。这些发现扩展了青年人关于ER和OCD的文献资料，并突出了临床医生作为OCD治疗的一部分，专门解决这种ER缺陷的重要性。
