A systematic review of mental health stigma reduction trainings for law enforcement officers.

Abstract

The aim of the present systematic review was to evaluate the outcome of law enforcement officer (LEO) trainings on mental health (MH) stigma and other outcomes. A systematic search of Pubmed, APA PsycInfo, and Cochrane Central Register of Controlled Trials was conducted to identify studies examining MH stigma trainings implemented within the LEO profession. Both randomized and nonrandomized studies were considered. Risk of bias was assessed via the Cochrane Risk-of-Bias tool for randomized trials and the Risk of Bias in Non-Randomized Study of Intervention (Version 2). The present review identified 18 studies comprised of 2,399 participants (Mage = 37.37, SD = 4.76). Samples were predominantly composed of police officers (k = 16), followed by correctional officers (k = 2) and both (k = 1). Although the review aimed to investigate trainings targeting institutional, public, and self-stigma, all studies implemented trainings intended to decrease public stigma. Outcomes evaluated across studies included attitudes toward MH, knowledge about MH, self-efficacy/confidence, behavioral responses/de-escalation skills, social distance, and awareness, support, and utilization of MH resources. Although the outcomes evaluated were somewhat consistent across studies, there was variability in how variables were defined and measured. Due to this, data could not be compared across studies, and thus, conclusions could not be drawn regarding which trainings demonstrated the most effectiveness in reducing MH. Despite the increased research investigating the outcomes of trainings on stigma within the LEO population, the variability in methodology and the high rate of bias exhibited across studies suggest that more rigorous and better quality evaluations are warranted.
