Suicidal ideation predicted by changes experienced from pre-treatment to 3-month postdischarge from residential substance use disorder treatment
Journal of Substance Abuse Treatment
Purpose: Individuals with substance use disorders (SUD) are at an elevated risk for suicide. Abstinence and drug-related treatment outcomes remain integral to SUD treatment, but recovery incorporates more than just the absence of substance use or mental illness and including positive mental health indices in assessment and treatment of suicidality is needed. Aims: The current study investigates the role of traditional indicators of recovery, as well as positive psychology constructs, in predicting suicidal ideation following residential SUD treatment. Method: The study utilized a longitudinal design with baseline and 3-month postdischarge follow-up assessments of 791 individuals who attended residential SUD treatment in Australia. Results: Rates of suicidal ideation decreased from baseline to follow-up, and the magnitude of change in most indices was associated with suicidal ideation at follow-up assessment. In a hierarchical logistic regression, baseline suicidal ideation, as well as a reduction in psychological distress, increase in refusal self-efficacy, and increase in self-forgiveness, emerged as significant predictors of follow-up suicidal ideation. The final model correctly classified 98.8% of participants as not experiencing SI, and 8.7% of participants as experiencing SI at follow-up, resulting in a total predictive accuracy of 86.9%. Conclusions: The results suggested that changes in traditional recovery indices may facilitate reductions in suicidality. As a whole, changes in positive psychology indices did not add to the ability to predict suicidal ideation once traditional indices had been accounted for, but this does not preclude the importance of these indices to SUD treatment and suicide prevention efforts.
