Group decision-making processes and group decision quality: moderation of mutual interest

Considering the existence of mutual interest in work groups within organisational context, we investigated three main decision-making processes: Personal task participation, negative socio-emotional behaviour and information domination. To illustrate the relationship between group decision-making processes and decision quality, we developed and tested a process model in which the final group decision quality could be predicted by abovementioned decision-making processes. Testing the moderation effect of mutual interest is considered as focus of study and its implications are discussed. Further expansion of our model involves process satisfaction as an intervening variable. The overall assessment of the group decision-making process was captured in the process satisfaction construct and its association with decision quality was analysed. The findings suggested that our 1st model supported the moderation of mutual interest with one exception. The findings of the 2nd model suggested that satisfaction of the group members about decision processes is strongly associated with decision quality.
