Cross-level interactions of individual trait positive affect, group trait positive affect, and group positive affect diversity

Abstract

The purpose of the current study is to examine the cross‐level three‐way interactions among individual trait positive affect (PA), group trait PA, and group PA diversity on individual work outcomes. Drawing on situation strength theory, we hypothesized that the relationship of individual trait PA with work outcomes depends on the strength of a group's affective contexts including group trait PA and PA diversity. The hierarchical linear modelling results for 261 employees in 42 South Korean organizational teams showed that individuals' trait PA was positively associated with their team commitment, job satisfaction, and organizational citizenship behaviour (OCB). The findings also demonstrated that individual trait PA had the strongest relationship with team commitment when group trait PA was low and PA diversity was high simultaneously. In addition, the relationship between individual trait PA and OCB was found to be stronger for affectively diverse groups than for homogeneous groups.
