Exploring meaning in life as a potential target for early intervention - results from a randomized trauma analogue...

Background: Previous studies in individuals exposed to stressors, including traumatic ones, have shown inverse relations between life meaning and distress. Furthermore, meaning-related treatments can benefit (traumatic) stressor-exposed individuals. However, the evidence regarding the effect of life meaning interventions on PTSD symptoms is limited. Moreover, early post-stressor interventions preventing distress are needed. This study investigated the effects of a short, online life meaning intervention after an analogue traumatic stressor on intrusions and anxiety following the intervention, intrusions over a week, and explored distress and life meaning differences after a week.Method: Following an analogue traumatic stressor (i.e. an aversive film), N = 237 participants were randomized to a life meaning intervention, an active or inactive control condition. Participants completed questionnaires in the laboratory, in an online seven-day diary, and at one-week follow-up.Results: The intervention resulted in significantly lower post-intervention state anxiety and higher life meaning, but not significantly less severe wait-period intrusions than the control conditions. Intrusions in the subsequent week as well as depression, anxiety, PTSD, and life meaning after a week did not significantly differ between the conditions.Conclusion: This intervention showed promising temporary effects on anxiety and life meaning after a trauma analogue, but no significant longer-term effects and no effects on PTSD symptoms including intrusions. Meaning-related interventions for PTSD target stressor-related meaning-making rather than life meaning. Thus, future studies may benefit from implementing more intense interventions to extend effects on general distress, as well as stressor-addressing meaning interventions to elicit stressor-related meaning-making.
