The validity of the Seasonal Pattern Assessment Questionnaire (SPAQ) was examined by interviewing 81 individuals who had participated in an earlier community survey of seasonal affective disorder (SAD) in Iceland. When SAD and subsyndromal SAD (S-SAD) were combined into a 'winter problem' group, the questionnaire's sensitivity, specificity and positive predictive value for that group were 94%, 73% and 45%, respectively. The SPAQ discriminated poorly between SAD and S-SAD, and hence it had a poor case-finding ability for SAD. Clinical evaluation verified a diagnosis of SAD in individuals who had no previous information about this syndrome. The questionnaire furthermore identified a group of individuals who had generalized anxiety and marked seasonal variations. Clinical evaluation arrived at a similar prevalence rate of SAD as the questionnaire.
通过对81名曾参与冰岛季节性情感障碍(SAD)早期社区调查的个体进行访谈,检验了季节性模式评估问卷(SPAQ)的有效性。当将SAD和亚综合征性SAD(S-SAD)合并为一个“冬季问题”组时,该问卷对该组的敏感性、特异性和阳性预测值分别为94%、73%和45%。SPAQ对SAD和S-SAD的区分能力较差,因此其对SAD的病例发现能力较差。临床评估证实了此前对该综合征一无所知的个体患有SAD。此外,该问卷还识别出了一组患有广泛性焦虑且有明显季节性变化的个体。临床评估得出的SAD患病率与问卷得出的相似。
