INTRODUCTION
The Yale-Brown Obsessive Compulsive Scale-Shopping Version (YBOCS-SV) is considered the gold standard in the assessment of shopping severity. It is designed to assess cognitions and behaviors relating to compulsive buying behavior. The present study aims to assess the validity of the Brazilian version of this scale.
METHODS
For the study, composed the sample 610 participants: 588 subjects of a general population and 22 compulsive buyers. Factorial analysis was performed to assess the relations and the correlation between the YBOCS-SV, the Compulsive Buying Scale (CBS), and Richmond Compulsive Buying Scale (RCBS), was assessed using Pearson coefficient, for study of convergent and divergent validity. Cronbach's alpha coefficients were used to assess internal consistency.
RESULTS
The results show good to excellent psychometric parameters for the YBOCS-SV in its Brazilian version. With regard to correlations, the YBOCS-SV is inversely and proportionally correlated with CBS and the RCBS, indicating that the YBOCS-SV is an excellent instrument for screening compulsive buying. The YBOCS-SV presented high alpha coefficient of Cronbach's alpha (0.92), demonstrating good reliability.
CONCLUSIONS
The Brazilian version of the YBOCS-SV is indicated to diagnose compulsive buying disorder, and likely use for the purposes intended in the Brazilian population.
简介
耶鲁-布朗强迫性购物量表-购物版本（YBOCS-SV）被认为是评估购物严重程度的金标准。它旨在评估与强迫性购买行为相关的认知和行为。本研究旨在评估该量表的巴西版本的有效性。
方法
研究共纳入了 610 名参与者：588 名普通人群和 22 名强迫性购买者。进行因子分析以评估 YBOCS-SV、强迫性购买量表（CBS）和里士满强迫性购买量表（RCBS）之间的关系和相关性，使用皮尔逊系数评估收敛和发散效度。使用克朗巴赫的阿尔法系数评估内部一致性。
结果
巴西版 YBOCS-SV 的心理测量参数良好至优秀。就相关性而言，YBOCS-SV 与 CBS 和 RCBS 呈负相关且成比例，表明 YBOCS-SV 是筛查强迫性购买的极好工具。YBOCS-SV 呈现出高克朗巴赫的阿尔法系数（0.92），表明可靠性良好。
结论
巴西版 YBOCS-SV 可用于诊断强迫性购买障碍，并且可能在巴西人群中用于预期目的。
