Perceived social support moderates the relations between mental health symptoms and current suicidal ideation.

ABSTRACT

Despite efforts to identify risk factors associated with suicidal ideation (SI), less work has been conducted to highlight protective factors to promote prevention. Perceived social support has been shown to positively impact a wide range of psychological outcomes; however, prior efforts exploring whether perceived social support moderates the relationship between mental health (MH) symptoms and current SI among men and women have been hampered by limitations. To address knowledge gaps, data from the Comparative Health Assessment Interview Research Study was used to evaluate whether (a) perceived social support moderates the relationship between mental health symptoms (posttraumatic stress, anxiety, alcohol use, depressive) and current SI among veterans and nonveterans; (b) the strength of this moderating effect varies by gender and veteran status; and (c) the strength of this moderating effect varies by social support source (significant other, friend, family). Results suggest that perceived social support is more protective against SI for those with lower levels of mental health symptoms (≤ 25th percentile) than for those with higher symptom levels (≥ 75th percentile). Findings were largely consistent across study groups, support sources, and mental health symptoms examined; however, a significant moderating effect on the alcohol use-SI relationship was only observed for veteran men. Those with a lower mental health symptom severity may receive more benefit from strategies aimed at increasing perceived social support compared to those with higher symptom severity. Research is needed to match protective factors to individual phenotypes, with the goal of engaging those living with SI in more effective interventions.
