Meaning in Life (but Not Life Satisfaction) Moderates the Effects of Battlefield Experiences on Suicidal Ideation and Anxiety

Objective: Although research has been conducted in the last decade distinguishing between meaning in life and life satisfaction, no research has examined whether their potential moderating role in mental health problems is distinct. Among military personnel, mental health is paramount, and suicide is one of the leading causes of death. Method: Data were collected to determine the potential moderating effects of meaning in life and/or life satisfaction of battlefield experiences on depression, anxiety, and thoughts about death (including suicidal ideation). Data were collected on 851 total military personnel, spanning two distinct survey administrations, who reported at least one combat deployment. Results: Findings suggest that meaning in life has a significant moderating effect on the impact of life-threatening experiences on anxiety and thoughts about death (including suicidal ideation), but no moderating effect on depression. Life satisfaction had no significant moderating role for any mental health outcome. Conclusions: This research suggests that meaning in life is a significant buffer against certain negative mental health outcomes stemming from life-threatening experiences.
