Objective Criminal justice involvement, substance use, and suicide pose significant public health concerns; however, the unique and synergistic effects of these experiences among high-risk individuals remain understudied. We hypothesized positive main effects for alcohol-related severity, drug-related severity, current criminal justice involvement, and thwarted belonging (TB) on suicide ideation history (SIH) and suicide attempt history (SAH) and that TB would moderate these associations. Method We report on cross-sectional analyses of self-report assessments completed by 824 adult residential substance use patients. Results Multinomial logistic regression analyses indicated that as alcohol- and drug-related severity increases, the probability of SIH and SAH increases; however, TB was only associated with a higher SIH probability. Significant two-way interactions (current criminal justice involvement*TB; alcohol-related severity*TB) indicated that (1) those high in TB with current criminal justice involvement were more likely to report a SIH than those without current criminal justice involvement; and (2) those low in TB and alcohol-related severity had the lowest SAH probability, whereas those low in TB and high in alcohol-related severity had the highest SAH probability. Conclusion The unique and combined effects of interpersonal and contextual risk factors may improve suicide risk conceptualization and assessment, and allow for tailored treatments for this high-risk population.
