In preregistered secondary data analyses, we compared the predictive utility of trait affect and average daily affect for predicting three health outcomes across nine years (N = 1,376). Trait positive and negative affect were assessed using a 25-item dispositional questionnaire. Average daily affect was assessed as the mean of eight daily diary reports of the same items. Trait affect and average daily affect both had medium associations with self-reported general health and chronic health conditions. Moreover, both types of affect predicted mortality when adjusting for baseline health and demographics. Effect sizes were comparable for trait compared to daily affect. These findings demonstrate convergent predictive validity of trait and daily affect measures.
在预先注册的二次数据分析中，我们比较了特质情绪和每日平均情绪对预测九年中三种健康结果的预测效用（N = 1376）。使用一份包含25个条目的特质问卷评估特质积极和消极情绪。每日平均情绪被评估为相同项目的八份每日日记报告的平均值。特质情绪和每日平均情绪与自我报告的总体健康和慢性健康状况均具有中等程度的关联。此外，在调整基线健康和人口统计学因素后，这两种情绪类型均能预测死亡率。与每日情绪相比，特质情绪的效应大小相当。这些发现证明了特质情绪和每日情绪测量方法具有趋同的预测效度。
