OBJECTIVE To develop and examine the psychometric properties of the Children's Yale-Brown Obsessive-Compulsive Scale Second Edition (CY-BOCS-II) in children and adolescents with obsessive-compulsive disorder (OCD). METHOD Youth with OCD (N = 102; age range 7-17 years), who were seeking treatment from 1 of 2 specialty OCD treatment centers, participated in the study. The CY-BOCS-II was administered at an initial assessment, and measures of OCD symptom severity, anxiety and depressive symptoms, behavioral and emotional problems, and global functioning were administered. Inter-rater and test-retest reliabilities were assessed on a subsample of participants (n = 50 and n = 31, respectively) approximately 1 week after intial assessment. RESULTS The CY-BOCS-II demonstrated moderate-to-strong internal consistency (α = 0.75-0.88) and excellent inter-rater (intraclass correlation coefficient = 0.86-0.92) and test-retest (intraclass correlation coefficient = 0.95-0.98) reliabilities across all scales. Construct validity was supported by strong correlations with clinician-rated measures of OCD symptom severity and moderate correlations with measures of anxiety symptoms. Exploratory factor analysis showed a 2-factor structure, which was generally inconsistent with its adult counterpart, the Yale-Brown Obsessive-Compulsive Scale Second Edition. CONCLUSION Initial findings support the CY-BOCS-II as a reliable and valid measure of obsessive-compulsive symptoms in youth.

儿童耶鲁-布朗强迫症量表第二版的开发和心理测评。

目的开发和研究儿童强迫症量表（OCD）的儿童耶鲁布朗强迫症量表第二版（CY-BOCS-II）的心理测量特性。方法从2个专业OCD治疗中心中的1个寻求治疗的OCD青年（N = 102；年龄范围7-17岁）参加了该研究。CY-BOCS-II在初步评估时给药，并测量了强迫症症状严重程度，焦虑和抑郁症状，行为和情绪问题以及整体功能。初次评估后约1周，对参与者的子样本（分别为n = 50和n = 31）进行了评估者间信度和重测信度的评估。结果CY-BOCS-II表现出中等至强内部一致性（α= 0.75-0。88）以及在所有量表上均具有出色的内部评估者（类内相关系数= 0.86-0.92）和重测（类内相关系数= 0.95-0.98）。与临床评价的强迫症症状严重程度的强相关性和与焦虑症状的中等程度的相关性共同支持了结构的有效性。探索性因素分析显示了2因子结构，该结构通常与成年的Yale-Brown强迫症量表第二版不一致。结论初步发现支持CY-BOCS-II是一种可靠且有效的青年强迫症症状测量方法。与临床评价的强迫症症状严重程度的强相关性和与焦虑症状的中等程度的相关性共同支持了结构的有效性。探索性因素分析显示了2因子结构，该结构通常与成年的Yale-Brown强迫症量表第二版不一致。结论初步发现支持CY-BOCS-II是一种可靠且有效的青年强迫症症状测量方法。与临床评价的强迫症症状严重程度的强相关性和与焦虑症状的中等程度的相关性共同支持了结构的有效性。探索性因素分析显示了2因子结构，该结构通常与成年的Yale-Brown强迫症量表第二版不一致。结论初步发现支持CY-BOCS-II是一种可靠且有效的青年强迫症症状测量方法。
