Previous experiences with groups (good and bad) inform people’s decisions to join prospective groups. Individuals will compare the rewards of the group (e.g. belonging, emotional support, informational support, instrumental support, spiritual support; see Uchino, 2004 for an overview) against potential costs (e.g. time, emotional energy). Those with negative or 'mixed' experiences with previous groups will likely be more deliberate in their assessment of potential groups to join, and with which groups they choose to join.
