Emotional problems and intellectual disability: comparing groups with and without forensic involvement

Abstract

Purpose Individuals with intellectual disability (ID) are known to experience increased emotional and behavioural concerns. The study aims to assess whether detained ID patients with a forensic history (IDPF) have increased difficulty managing their impulse control in comparison to detained ID patients without a forensic history (IDP). Using the externalising behaviour problems (EBP) subscale of the EPS, the study aims to compare the differences between the IDFP and IDP groups. Design/methodology/approach A total of 60 patients with ID detained under the Mental Health Act 1983 (Revised 2007) were assessed using the behaviour rating scale of the EPS. The outcome scores of the EBP were used to examine any observed differences between the scores of forensically involved patients [n = 34] and those without a forensic history [n = 26]. It was hypothesised that patients with a forensic history would display higher scoring on externalised behavioural problems (EBP) than patients without such a history. Findings Non-parametric testing revealed that there were no significant differences in EBP scoring between the two sample groups. These findings indicate that, for patients in the present study, no differences were detected in the presentation of these two distinct groups. In fact, with the exception of the verbal aggression subscale of the EBP, the other three subscales (physical aggression, non-compliance and hyperactivity) show that actually the IDP group displayed the higher ranked means in these subscales when compared with the forensically involved group. Originality/value These results indicate possible increased treatment needs within the IDP group and question whether offending history is necessarily a reliable predictor of ongoing hostility and behavioural concerns within similar inpatient services.
