The main screening tool for Seasonal Affective Disorder (SAD) is the Seasonal Pattern Assessment Questionnaire, but its reliability and validity have been thrown into doubt by several studies.
In this study we developed a new questionnaire, the Seasonal Health Questionnaire (SHQ), which is scored by computer to derive the four main operational criteria for diagnosis of SAD. A group of clinically diagnosed SAD patients was contrasted with a group of patients with recurrent non-seasonal depressive disorder using the SPAQ and the SHQ.
The SHQ could be completed without difficulty by patients with long histories of recurrent mood disorder. The SPAQ and the Rosenthal Criteria were the least specific of the criteria for identifying SAD - misclassifying many non-seasonal patients.
After further development the SHQ may be a more appropriate screening instrument for SAD. The SPAQ should no longer be used for this purpose as it gives misleadingly high estimates of prevalence.
季节性情感障碍（SAD）的主要筛查工具是季节性模式评估问卷，但多项研究对其可靠性和有效性提出了质疑。
在本研究中，我们开发了一种新的问卷，即季节性健康问卷（SHQ），该问卷通过计算机评分得出诊断SAD的四个主要操作标准。使用SPAQ和SHQ将一组临床诊断为SAD的患者与一组复发性非季节性抑郁症患者进行对比。
患有长期复发性情绪障碍病史的患者能够毫无困难地完成SHQ。SPAQ和罗森塔尔标准在识别SAD的标准中特异性最低——将许多非季节性患者误分类。
经过进一步开发，SHQ可能是一种更适合用于SAD的筛查工具。SPAQ不应再用于此目的，因为它对患病率的估计过高，会产生误导。
