OBJECTIVE Our aim is to investigate the impact of childhood ADHD comorbidity on the clinical features of obsessive compulsive disorder (OCD). METHOD Ninety-five adult outpatients with a diagnosis of OCD were assessed by using the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version, ADHD module, and the Yale-Brown Obsessive Compulsive Scale. Patients with or without childhood ADHD were compared in terms of the sociodemographic and clinical features, psychiatric comorbidities, and rating scales. RESULTS The rate of episodic course of OCD (p < .001), religious and sexual obsessions (p = .009, p = .020, respectively), lifetime comorbidity of bipolar disorder (BD), social anxiety disorder (SAD; p = .001, p = .009, respectively), and tic disorder (TD) comorbidity (p < .001) were higher in the OCD + ADHD group than in the OCD without ADHD group. CONCLUSION Childhood ADHD may be associated with higher rates of BD, SAD, and TD comorbidity and episodic course of OCD as well as higher frequency of certain types of obsessions.

强迫症患者儿童多动症合并症的特征。

目的我们的目的是调查儿童多动症合并症对强迫症（OCD）临床特征的影响。方法使用学龄儿童-现成和终生版情感障碍和精神分裂症时间表，ADHD模块和耶鲁-布朗强迫症量表，对九十五名诊断为强迫症的成人门诊病人进行评估。对有或没有儿童多动症的患者进行了社会人口统计学和临床​​特征，精神病合并症和评定量表的比较。结果强迫症的发作过程发生率（p <.001），宗教和性强迫症（p = .009，p = .020），双相情感障碍的终生合并症（BD），社交焦虑症（SAD； p = .001，p分别为.009）和抽动障碍（TD）合并症（p <。001）在OCD + ADHD组中高于在没有ADHD组的OCD中。结论儿童多动症可能与BD，SAD和TD合并症的发病率较高以及强迫症的发作过程以及某些类型的强迫症发生频率较高有关。
