The SPAQ is a widely used tool for identifying possible cases of recurrent major depressive disorders with a seasonal pattern. However, its test-retest reliability, sensitivity, specificity, positive predictive value, negative predictive value, efficiency and predictive validity have not previously been formally assessed. Forty-seven subjects who fulfilled the DSMIIIR criteria for a major depressive disorder with a seasonal pattern were traced and re-interviewed after five to eight years. The SPAQ was found to have a positive predictive value of 48% and an efficiency of 57% in identifying cases of SAD confirmed by follow-up. The test-retest reliability was low. There was a mean difference in seasonality score between the first and second test of 3.17 +/- 4.7 (mean +/- 1 S.D.). Although the SPAQ is a rapid method of collecting information about recent seasonal variation, it has low test-retest reliability and on its own is unable to predict the seasonality of the future course of illness.
季节性模式复发性重度抑郁症自评问卷（SPAQ）是一种广泛用于识别可能病例的工具。然而，其重测信度、敏感性、特异性、阳性预测值、阴性预测值、效率和预测效度此前尚未得到正式评估。对47名符合DSMIIIR标准的季节性模式重度抑郁症患者进行追踪，并在5至8年后重新访谈。结果发现，在识别经随访确诊的季节性情感障碍（SAD）病例方面，SPAQ的阳性预测值为48%，效率为57%。重测信度较低。第一次和第二次测试之间的季节性得分平均差异为3.17 +/- 4.7（平均值 +/- 1标准差）。尽管SPAQ是一种收集近期季节性变化信息的快速方法，但其重测信度较低，仅凭自身无法预测未来病程的季节性。
