Meta Analysis
Cohesion and performance in groups: a meta-analytic clarification of construct relations.
Previous meta-analytic examinations of group cohesion and performance have focused primarily on contextual factors. This study examined issues relevant to applied researchers by providing a more detailed analysis of the criterion domain. In addition, the authors reinvestigated the role of components of cohesion using more modern meta-analytic methods and in light of different types of performance criteria. ⋯ Mullen and C. Copper's (1994) meta-analysis, the 3 main components of cohesion were independently related to the various performance domains. Implications for organizations and future research on cohesion and performance are discussed.

Prior research has examined both the antecedents to and outcomes of work-family conflict. However, little is known about the existence and efficacy of behavioral strategies that may be used by individuals to reduce the amount of stressors experienced both on the job and at home, which result in work-family conflict. ⋯ In general, these results held true even when additional variables (e.g., hours worked, gender, job involvement, family involvement, social support, and supervisor support) were controlled. Implications of these results are discussed.

Meta Analysis
A meta-analytic study of general mental ability validity for different occupations in the European community.
A comprehensive meta-analysis of the validity of general mental ability (GMA) measures across 12 occupational categories in the European Community (EC) is presented. GMA measures showed that there is validity generalization and large operational validities for job performance and training success in 11 occupational groups. ⋯ In general, results were similar to those found in the United States, although the European findings showed a slightly larger magnitude of operational validity in some cases. Theoretical and practical implications of these findings for personnel selection are discussed. ((c) 2003 APA, all rights reserved)

Acceptance, the willingness to experience thoughts, feelings, and physiological sensations without having to control them or let them determine one's actions, is a major individual determinant of mental health and behavioral effectiveness in a more recent theory of psychopathology. This 2-wave panel study examined the ability of acceptance also to explain mental health, job satisfaction, and performance in the work domain. ⋯ These beneficial effects of having more job control were enhanced when people had higher levels of acceptance. The authors discuss the theoretical and practical relevance of this individual characteristic to occupational health and performance.
