Despite the increasing popularity of peer-evaluation methods (Hedge, Borman & Birkeland, 2001), only a handful of studies have examined performance-related consequences of these methods. Moreover, these few studies have generated largely mixed results. Some researchers have found peer-evaluation to have a positive impact on managerial effectiveness and relational and task focused team processes. Others have argued that such appraisals can turn into popularity contests, and generally harm team member relationships, team processes, and group morale. Additionally, most research to date has been conducted on students; that done in the field has assumed no differences in participants’ occupational status. Consequently, we know little about the impact of peer-evaluation in field settings in which occupational status differences exist among the participants, as is the case of multi-disciplinary work teams. Using hospital wards as an empirical referent, the objective of the current study is to enhance our understanding of the impact of peer-evaluation on peer relations (i.e., helping behaviors, satisfaction with the group) and task-related processes (i.e., workload sharing, responsibility for team work) among members of multi-disciplinary work teams.
Our study examined the impact of a developmental peer-evaluation on 139 physicians and nurses in six internal medicine wards in a tertiary health care center. The intervention was conducted in three wards and confidential feedback was handed out to the participants. Team processes were measured before and after the intervention, and in parallel points of time in the control ward. The study was conducted over a half a year. The results revealed that peer-evaluation intervention in heterogeneous teams of physicians and nurses was associated with enhanced team members’ relationships as well as improved task-related processes for physicians but not for nurses.
