Obsessive-compulsive disorder (OCD) is characterized by underlying obsessions and yielding/nonyielding compulsions, which often leads to significant levels of distress for the individual. Recently, obsessive-compulsive symptoms have been grouped into various symptom dimensions. The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) gives a comprehensive picture regarding symptom severity in each individual dimension of OCD, while also providing a global severity score.
The psychometric properties of the Bengali adaptation of DY-BOCS have been assessed in this study.
A cross-sectional study was performed on 80 individuals suffering from OCD as per the ICD-10 DCR criteria. The Bengali version of the DY-BOCS and other scales for OCD, anxiety, and depression were administered to all of them. Inter-rater reliability was assessed for 34 individuals, and agreement between self and clinician-rated version of DY-BOCS was studied for 60 individuals. Internal consistency for items in a particular dimension of DY-BOCS, convergent validity, and divergent validity were also assessed.
Internal consistency was found to be excellent (Cronbach's α > 0.90 in all domains), and inter-rater reliability was found to be good to excellent for all the six dimensions of the DY-BOCS (intraclass correlation values >0.80 for aggressive and miscellaneous domains and >0.90 in all other domains). High correlation was found between self and clinician-rated versions of DY-BOCS for the age group 18-35 years, the highest correlations being found for the Contamination (r = 0.82) and Aggressive domains (r = 0.75), while it was found to decrease in the older age group. Convergent validity and divergent validity were found to be satisfactory.
The psychometric attributes of the Bengali version of DY-BOCS appear to be satisfactory and thus can be reasonably administered to the population having Bengali as their mother tongue.
强迫症（OCD）的特征是存在潜在的强迫观念以及顺从性/非顺从性强迫行为，这常常给个体带来显著程度的痛苦。最近，强迫症状已被归类为各种症状维度。维度耶鲁-布朗强迫量表（DY-BOCS）全面呈现了强迫症各个维度的症状严重程度，同时还提供了一个总体严重程度评分。
本研究评估了孟加拉语版DY-BOCS的心理测量特性。
根据ICD-10 DCR标准，对80名强迫症患者进行了横断面研究。对所有患者施测孟加拉语版DY-BOCS以及其他用于评估强迫症、焦虑和抑郁的量表。对34名个体评估了评分者间信度，并对60名个体研究了DY-BOCS自我评定版与临床医生评定版之间的一致性。还评估了DY-BOCS特定维度项目的内部一致性、收敛效度和区分效度。
发现内部一致性极佳（所有领域的克朗巴哈α系数>0.90），并且DY-BOCS的所有六个维度的评分者间信度均为良好至极佳（组内相关值在攻击和杂项领域>0.80，在所有其他领域>0.90）。在18 - 35岁年龄组中，DY-BOCS自我评定版与临床医生评定版之间发现高度相关，在污染维度（r = 0.82）和攻击维度（r = 0.75）中相关性最高，而在年龄较大的组中相关性降低。发现收敛效度和区分效度令人满意。
孟加拉语版DY-BOCS的心理测量属性似乎令人满意，因此可以合理地施测于以孟加拉语为母语的人群。
