Many cheers make light the work: how social support triggers process gains in teams

Social support from fellow team members has been neglected as a unique source of process gains in teams. This paper seeks to introduce the Model of Social Support within Teams (MSST) that explicates testable hypotheses on effects of team partners' affective and task‐related support on team performance.

A theoretical model is proposed that specifies the psychological mechanisms by which affective and task‐related support from fellow team members evoke process gains in teams compared with individual work. Moreover, moderators and potential limits of these beneficial effects are described. The model integrates results from experimental research on behaviour in small groups with findings from field studies on organisational citizenship behaviour, team cognition, and efficacy beliefs at the individual and team level.

It is predicted that affective support predominantly increases individual members' motivation, while task‐related support predominantly improves coordination within teams. Moreover, various moderators (team members' dispositions, task design, team characteristics) are considered.

According to this analysis, social support can be an effective measure to trigger process gains in teams, and thus to increase team performance and organisational success. Concrete interventions to foster social support in teams are derived from the model, among them task design, consideration of social attitudes in selection and staffing, and team training.

This paper introduces a theoretical model explicating a previously neglected source of process gains in teams. In contrast with other sources of process gains, social support relates to the interaction among team members and integrates both motivation and coordination gains.
