We examined the consistency reliability of the widely used Seasonal Pattern Assessment Questionnaire (SPAQ). In total, 587 questionnaires from a random sample of the general population were analysed. The 6 items of the Seasonality Scale Index (SSI) correlated fairly well, and consequently this scale proved to have a high internal consistency (alpha = 0.82). Items from the SSI that measure seasonal variations in sleep and weight were consistent with other SPAQ scales that also measure these dimensions. Since the questionnaires analysed were from an epidemiological study, the high consistency reliability shows that the symptoms probed for by the SSI, tend to cluster in susceptible individuals in the general population.
我们检验了广泛使用的季节性模式评估问卷（SPAQ）的一致性信度。总共分析了来自普通人群随机样本的587份问卷。季节性量表指数（SSI）的6个项目相关性相当好，因此该量表具有较高的内部一致性（α = 0.82）。SSI中测量睡眠和体重季节性变化的项目，与其他也测量这些维度的SPAQ量表一致。由于所分析的问卷来自一项流行病学研究，较高的一致性信度表明，SSI所探究的症状往往在普通人群中的易感个体中聚集。
