Obsessive-Compulsive Disorder (OCD) is a mental disorder that interferes with daily functioning and may arise during childhood. The current study is the first attempt by Italian researchers to validate the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS).
The study's primary aim was to investigate the best CY-BOCS model fit, adopting a Bayesian model comparison strategy, among four different factor models: a one-factor model; a two-factor model based on Obsessions and Compulsions; Storch et al.'s and Mc Kay et al.'s two-factor model based on Disturbance and Severity. The study also aimed to investigate the types of treatments found in a sample of Italian OCD children patients.
The study sample was made up of 53 children with OCD and 14 children with Tourette Syndrome and TIC.
An analysis of our data demonstrated that the Obsessions and Compulsions model was the most plausible one, as it demonstrated the best fit indices, strong convergent validity, and good reliability. The study results additionally uncovered that 24.5% of the children in the OCD sample had not yet begun any treatment pathway a year after a diagnosis was formulated.
These findings suggest that the Obsessions and Compulsions scales of the CY-BOCS separately represent appropriate instruments to evaluate children with OCD.
强迫症（OCD）是一种干扰日常功能且可能在儿童期出现的精神障碍。本研究是意大利研究人员首次尝试验证儿童耶鲁-布朗强迫症量表（CY-BOCS）。
该研究的主要目的是采用贝叶斯模型比较策略，在四种不同的因子模型中探究最佳的CY-BOCS模型拟合度，这四种模型分别是：单因子模型；基于强迫观念和强迫行为的双因子模型；斯托奇等人以及麦凯等人基于干扰和严重程度的双因子模型。该研究还旨在调查意大利强迫症儿童患者样本中所采用的治疗类型。
研究样本由53名患有强迫症的儿童以及14名患有抽动秽语综合征和抽动障碍的儿童组成。
对我们数据的分析表明，强迫观念和强迫行为模型是最合理的模型，因为它显示出最佳的拟合指数、较强的收敛效度和良好的信度。研究结果还发现，强迫症样本中有24.5%的儿童在确诊一年后尚未开始任何治疗途径。
这些发现表明，CY-BOCS的强迫观念和强迫行为量表分别是评估强迫症儿童的合适工具。
