Similarity in the experience of state affect is a common phenomenon for work team members and has been shown to have important consequences on team behavior and performance. We provide a comprehensive overview of the current state of research on group affective tone, including the development of group affective tone through affective convergence mechanisms, the conceptualization and operationalization of group affective tone, and the theoretical and practical consequences of positive and negative affective tones for group behavior and group performance. Finally, we highlight some emerging research directions that may provide promising avenues for future understanding of the complexity inherent in the formation and influence of state group affect.

The objective of our study was to investigate whether life satisfaction and depressive symptoms are independent predictors of mortality in a non-Western sample of adults. The sample included 5,131 adults (aged 50 -95 at baseline) in Taiwan who participated in the Survey of Health and Living Status of the Near Elderly and Elderly. There were 1,815 deaths recorded over a 10-year period. Higher life satisfaction significantly predicted lower risk of mortality after controlling for age, sex, education, marital status and health status. Depressive symptoms significantly predicted higher risk of mortality. A significant interaction with age revealed that the protective effect of life satisfaction weakened with age. The results suggest that life satisfaction and depressive symptoms independently predict mortality risk in adults.

The idea that affect plays a key role in leader-member exchange (LMX) processes is not new, but it has become a subject of considerable research attention since the turn of the Millennium. This interest has, however, resulted in a multiplicity of views that have tended to obfuscate rather than clarify the affect-LMX nexus. To deal with this lack of clarity, we conducted a systematic integration of affect-LMX literature published in leading journals since 2000, including the role of personal affectivity, discrete affect, emotional intelligence, emotional labor, and affective climate. We structured our review using a multilevel framework of affect that encompasses five levels of analysis: (1) within-person, (2) between persons,(3) interpersonal, (4) team, and (5) organizational levels; as well as consideration of cross-level effects. We address in particular three fundamental issues that we argue may have hampered the development of the affect-LMX nexus in the literature: theoretical diversity, problems of data analysis, and measurement issues. We conclude by discussing opportunities for future research across the different levels and develop a set of research questions that we hope will help to promote research into the role of affect in LMX.
