ABSTRACT
BACKGROUND: Rates of psychiatric disorders are highly prevalent among prison inmates, and recent evidence confirms over-representation of youths and adults with attention deficit hyperactivity disorder (ADHD). The risk for psychiatric co-morbidity may be greater among offenders with ADHD. We undertook a systematic review and meta-analysis of reported rates of co-existing psychiatric morbidity with ADHD in prison samples. METHOD: Studies published from 1980 to 2015 were identified using five bibliographic indexes, review articles and reference lists. Included studies had a defined ADHD group and provided additional prevalence on at least one of the following: conduct disorder, substance use disorder, mood disorder, anxiety disorder, or personality disorder. We performed meta-analytical estimates of the prevalence of each co-morbid disorder within ADHD, and estimated the risk for co-existing disorders among prisoners with ADHD by pooling odds ratios (OR) with 95% confidence intervals. RESULTS: Eighteen studies with data for 1615 with ADHD and 3128 without ADHD were included. The risk (OR) of all psychiatric morbidity is increased among adult inmates with ADHD. Associations in youths with ADHD were restricted to mood disorder (OR 1.89, 95% confidence interval 1.09-3.28). CONCLUSIONS: This study quantifies the extent of co-morbidity presented by offenders with ADHD, especially adults. The differences between risk estimates for youths and adults indicate an incremental effect in both frequency and severity for the development of further co-morbid pathology through adulthood. The findings have implications for clinical intervention and for criminal justice policy.

BACKGROUND: Studies report the variable prevalence of attention deficit hyperactivity disorder (ADHD) in incarcerated populations. The aim of this meta-analysis was to determine the prevalence of ADHD in these populations. METHOD: Primary research studies reporting the prevalence (lifetime/current) of ADHD in incarcerated populations were identified. The meta-analysis used a mixed log-binomial model, including fixed effects for each covariate and a random study effect, to estimate the significance of various risk factors. RESULTS: Forty-two studies were included in the analysis. ADHD prevalence was higher with screening diagnoses versus diagnostic interview (and with retrospective youth diagnoses versus current diagnoses). Using diagnostic interview data, the estimated prevalence was 25.5% and there were no significant differences for gender and age. Significant country differences were noted. CONCLUSIONS: Compared with published general population prevalence, there is a fivefold increase in prevalence of ADHD in youth prison populations (30.1%) and a 10-fold increase in adult prison populations (26.2%).

There are very few, if any, valid and victim-specific situation empathy measures available at present for use with mentally disordered offenders. The aim of this study was to validate a modified version (VERA-2) of the Victim Empathy Response Assessment (VERA) tool which was developed earlier (Young et al., 2008) to enable victim-specific situation empathy measurement in offenders. A total of 55 mentally disordered in-patients residing in a maximum security hospital were assessed on VERA-2 as well as on measures of antisocial personality traits, global affective empathy, violent cognitions, and reported remorse for the index offence. The VERA-2 cognitive and affective empathy scales were negatively correlated with antisocial personality traits and violent cognitions, and positively related to remorse for the index offence. Global affective empathy was positively related to VERA-2 affective empathy. Participants with a history of sexual offending had significantly higher cognitive empathy than other offenders. Acceptance of violence and remorse for the index offence were the best predictors of both cognitive and affective empathy. The findings suggest that the VERA-2 is a valid instrument for measuring victim empathy among mentally disordered offenders, and may prove useful in the context of future risk assessment and outcomes in this population.
