季节性信念问卷(SBQ)是冬季季节性情感障碍(SAD)特有的认知脆弱性的26个条目的自我报告测量，包括对季节、光照可用性和天气条件的不适应想法。在一个已知的组比较中，目前患有SAD的抑郁症成年人的SBQ得分显著高于目前患有非季节性严重抑郁障碍(MDD)的抑郁症成年人和健康对照组，并且MDD组的SBQ得分显著高于对照组。使用该数据库，本研究探索了使用SBQ分界值来区分SAD和MDD的预测有效性。受试者操作员特征曲线分析使用SBQ总分来预测SAD与MDD、SAD与对照、MDD与对照状态。从多变量Logistic回归和SBQ子量表得出的SBQ子量表组合得分被检验为替代预测因子。SBQ总分以132为切点，对区分SAD和MDD有较好的预测能力(C统计量=.792，敏感度=.798，特异度=.794)。SBQ子量表组合得分对SAD/MDD区分的预测能力略有提高(C-统计量=.813)，敏感性较好(.930)，但特异性较差(.571)。相比之下，抑郁症认知易损性的通用衡量标准--功能障碍态度量表--的得分在区分SAD和MDD方面很差。SBQ总分在区分SAD患者和对照组方面表现良好(C-统计量=.962，敏感性=.939，特异性.873)，但对区分MDD患者和对照组的敏感性较差。结果支持在实践环境中使用SBQ筛查可能的SAD。
The Seasonal Beliefs Questionnaire (SBQ) is a 26-item self-report measure of a winter seasonal affective disorder- (SAD-) specific cognitive vulnerability consisting of maladaptive thoughts about the seasons, light availability, and weather conditions. In a known groups comparison, currently depressed adults with SAD had significantly higher SBQ scores than currently depressed adults with nonseasonal Major Depressive Disorder (MDD) and healthy controls, and the MDD group had significantly higher SBQ scores than controls. Using that database, this study explored the predictive validity of using a SBQ cutoff score to differentiate SAD from MDD. Receiver operator characteristic curve analyses used SBQ total score to predict SAD vs. MDD, SAD vs. control, and MDD vs. control status. SBQ subscale combined score, derived from multivariable logistic regression with SBQ subscales, was examined as an alternative predictor. SBQ total score with a cutpoint of 132 had good predictive ability for distinguishing SAD from MDD (C-statistic = .792, sensitivity = .798, specificity = .794). SBQ subscale combination score slightly improved predictive ability for the SAD/MDD distinction (C-statistic = .813), with better sensitivity (.930) but worse specificity (.571). In contrast, score on a generic measure of depressogenic cognitive vulnerability, the Dysfunctional Attitudes Scale, was poor for differentiating SAD from MDD. SBQ total score was excellent in discriminating SAD cases from controls with a cutpoint of 121 (C-statistic = .962, sensitivity = .939, specificity .873), but had poor sensitivity for discriminating MDD cases from controls. Results support using the SBQ to screen for probable SAD in practice settings.
