Abstract

Abstract: Suicidal thoughts and behaviors are highly prevalent public health problems with devastating consequences. There is an urgent need to improve our understanding of risk factors for suicide to identify effective intervention targets. The aim of this meta-analysis was to examine the magnitude and clinical utility of anxiety and its disorders as risk factors for suicide ideation, attempts, and deaths. We conducted a literature search through December 2014; of the 65 articles meeting our inclusion criteria, we extracted 180 cases in which an anxiety-specific variable was used to longitudinally predict a suicide-related outcome. Results indicated that anxiety is a statistically significant, yet weak, predictor of suicide ideation (OR = 1.49, 95% CI: 1.18, 1.88) and attempts (OR = 1.64, 95% CI: 1.47, 1.83), but not deaths (OR = 1.01, 95% CI: 0.87, 1.18). The strongest associations were observed for PTSD. Estimates were reduced after accounting for publication bias, and diagnostic accuracy analyses indicated acceptable specificity but poor sensitivity. Overall, the extant literature suggests that anxiety and its disorders, at least when these constructs are measured in isolation and as trait-like constructs, are relatively weak predictors of suicidal thoughts and behaviors over long follow-up periods. Implications for future research priorities are discussed. Highlights: We conducted a meta-analysis of anxiety predicting suicidal thoughts and behaviors. Anxiety was a significant risk factor for suicide ideation and attempts. As it has traditional been studied, anxiety is a weak predictor of suicidality. Future research must approximate current theories about risk factors for suicide.
