For this study, the authors developed a multi-item, multi-dimensional scale for peer evaluation encompassing five key dimensions: dependability, task and maintenance orientation, domineering behavior, free-riding behavior, and individual competence. They also tested the relationship between these dimensions and two outcome variables: overall evaluation and overall satisfaction. Results indicate that although dependability and competence influenced overall evaluation, task and maintenance orientation and free-riding behavior influenced overall satisfaction. The authors also tested the scales for stability across gender and prior familiarity with the group member and found them to be reasonably invariant. (Contains 4 tables.)
