= 98,436) in 122 longitudinal studies. A positive trend has been found for self-esteem, positive relationships, and mastery in prospective studies after both positive and negative events. We found no general evidence for the widespread conviction that negative life events have a stronger effect than positive ones. No genuine growth was found for meaning and spirituality. In the majority of studies with control groups, results did not significantly differ between event and control group, indicating that changes in the outcome variables cannot simply be attributed to the occurrence of the investigated life events. More controlled prospective studies are necessary to validate the genuine nature of postevent growth. Overall, the meta-analysis provides a systematic overview of the state of life event research and delineates important guidelines for future research on genuine growth.
