虽然在心理学研究中，单个项目可以节省时间和负担，但对其可靠性的担忧使得使用多项目测量成为默认的标准做法。尽管单个项目无法证明内部可靠性，但其标准有效性可以与多项目测量进行比较。使用生态瞬时评估数据，我们评估了重复测量的相关性，并构建了多层次交叉滞后模型，以评估单项目和多项目测量的并发和预测有效性。单项和多项指标之间的相关性在0.24到0.61之间。在29个独特的单项预测模型中，有27个单项预测模型表现出显著的预测有效性，在8组比较中，有一组单项预测模型表现出比多项预测模型更大的效应量。虽然多项措施通常比单项措施表现得更好，但在大多数情况下，多项措施的额外好处并不明显。目前的数据提供了支持，在密集的纵向设计中使用单项措施。
Although single items can save time and burden in psychology research, concerns about their reliability have made the use of multiple-item measures the default standard practice. Although single items cannot demonstrate internal reliability, their criterion validity can be compared with multiple-item measures. Using ecological momentary assessment data, we evaluated repeated measures correlations and constructed multilevel cross-lagged models to assess concurrent and predictive validity of single- and multiple-item measures. Correlations between the single- and multiple-item measures ranged from .24 to .61. In 27 of 29 unique single-item predictor models, single items demonstrated significant predictive validity, and in one of eight sets of comparisons, a single-item predictor exhibited a larger effect size than its multiple-item counterpart. Although multiple-item measures generally performed better than single items, the added benefit of multiple items was modest in most cases. The present data provide support for the use of single-item measures in intensive longitudinal designs.
