Multilevel researchers often gather individual-level data to measure group-level constructs. Within-group agreement is a key consideration in the measurement of such constructs, yet antecedents of within-group agreement have been little studied. The authors found that group member social interaction and work interdependence were significantly positively related to within-group agreement regarding perceptions of the work environment. Demographic heterogeneity was not significantly related to within-group agreement. Survey wording showed a complex relationship to agreement. Both evaluative items and socially undesirable items generated high within-group agreement. The use of a group rather than individual referent increased within-group agreement in response to descriptive items but decreased within-group agreement in response to evaluative items. Items with a group referent showed greater between-group variability than items with an individual referent.
多层次研究人员经常收集个体层面的数据来衡量群体层面的构念。组内一致性是衡量此类构念时的一个关键考虑因素,但组内一致性的前因却鲜有研究。作者发现,群体成员的社会互动和工作相互依存与对工作环境的认知方面的组内一致性显著正相关。人口统计学异质性与组内一致性无显著关联。调查措辞与一致性呈现出复杂的关系。评价性项目和社会期望性低的项目都产生了较高的组内一致性。使用群体而非个体作为参照对象,会增加对描述性项目回答的组内一致性,但会降低对评价性项目回答的组内一致性。以群体为参照对象的项目比以个体为参照对象的项目表现出更大的组间变异性。
