A systematic review of behavioral health interventions for suicidal and self-harming individuals in prisons and jails

This article reviews evaluation studies of interventions aimed at preventing and reducing incidents of suicide and self-harm among incarcerated individuals. Study design, sample characteristics, intervention procedures, study measures, and relevant results of each study are reviewed. The outcomes of interest include severity and frequency of self-harm episodes and suicidal ideation, scores on adaptive coping methods, scoring on the Beck Hopelessness scale and risk scores. The six evaluated studies are peer-reviewed, published between 1990 and 2015, and took place in the United States, the United Kingdom, and Pakistan. Treatment modalities widely vary across studies and include cognitive behavioral therapy, dialectical behavioral therapy, peer programming, staff intervention training, and uniquely-designed courses that incorporate various aspects from other treatment modalities. Due to the nature of the studies, only one multi-randomized controlled trial was identified. All identified studies had a pre- and post-treatment design either lacking a comparison group or containing 1–2 comparison groups and conduct follow-up of varying times. While Cognitive Behavioral Therapy (CBT) interventions and uniquely-tailored intervention programs suggest promising results, the general absence of comparison groups, the shortage of relevant evaluation studies and the inconsistency of behavioral outcome measurements compromise the capacity of this review. Further, definitional variances, particularly for self-injury (self-harm, non-suicidal self-injury [NSSI], deliberate self-harm, suicidal behavior, etc.) affect the ability to synthesize study results. This article aims to synthesize the literature results to identify the most effective interventions that would benefit from additional research.
