| Sinclair et al., 2016 [58] | Cross-sectional | Military personnel and veterans | 393 | Elevated PTSD and depression | MLQ | − | − | − | Mediation model: The presence of MiL, but not search for MiL negatively mediated the relationship between PTSD or depression and the trajectory from SI to SA |
| Lu et al., 2018 [59] | Longitudinal prospective | HIV-positive patients | 113 | − | MLQ | ↓ for presence of MiL, NS search for MiL | NS for presence of MiL; NS for search for MiL | − | Moderation model: The presence of MiL buffered the relationship between depressive symptoms and SI (no moderating effect between depressive symptoms and SA) |
Note: MiL = Meaning in life; SB = suicidal behavior; SI = suicidal ideation; SA = suicide attempt; MLQ = Meaning in Life Questionnaire; PTSD = post-traumatic stress disorder; NS = not significant.
