Stage 2 Registered Report Personal factors and group creative outcomes: A correlational meta-analysis

<ns3:p>Previous research has indicated that individual differences play a role in group creativity. Group creativity activities have different outcomes, leading to numerous ways to assess the effectiveness of these creative activities. To date, no meta-analysis has been performed on the relationship between the outcomes of the creative activity and personal factors of the group members. In this Registered Report, we conducted a meta-analysis (<ns3:italic>n</ns3:italic> = 11, <ns3:italic>k</ns3:italic> = 72) on the relationship between personal factors and group creativity outcomes. We found weak support for a positive correlation between self-efficacy and group creativity outcomes, between <ns3:italic>r</ns3:italic> = .04 and <ns3:italic>r</ns3:italic> = .67. We found weak support for a moderation effect of time constraint, with stronger relationships for conditions limited to 20 minutes as opposed to 10 minutes. Finally, we found that only a few studies could be included in the meta-analysis, because many studies (1) did not directly measure creativity, or (2) measured other, less common personal factors. We call for a more systematic and direct approach to measuring creativity and an improvement of open science practices in the field. Data and analysis can be found at https://osf.io/xwph9.</ns3:p>
