Cognitive predictors of violent incidents in forensic psychiatric inpatients

AbstractObjectives:To profile the current cohort of forensic psychiatric inpatients in the Republic of Ireland, comparing psychiatric healthcare and placement needs of long-stay patients with those more recently admitted.Method:All forensic psychiatric inpatients in the Central Mental Hospital, Dundrum on a census date were included in the study. Patients and key worker were interviewed using a standardised schedule and validated research instruments. Static and dynamic risk factors for violence including demographic, diagnostic and legal characteristics were supplemented by detailed chart review. Standardised anonymised case vignettes were presented to panels of forensic and community psychiatric multidisciplinary teams who assessed current and future treatment and placement requirements for the cohort.Results:There were 88 forensic psychiatric inpatients on the census date. Forty-three had lengths of stay over two years (17 over 20 years). Both patient groups were predominantly males with severe mental illness and histories of violent offending. The majority of the long-stay group were receiving regular parole and this group had lower levels of positive symptoms and comorbid substance misuse disorders. Significant gaps in existing rehabilitation inputs were identified. Almost half the long-stay patients were inappropriately placed. Thirty per cent of long-stay patients could be safely transferred to lower levels of security within six months and 63% within three years.Conclusions:Holding patients in conditions of excessive security impedes rehabilitation and has considerable human rights implications. Almost half of long-stay forensic psychiatric patients in Ireland are inappropriately placed. Barriers to discharge include legislative inadequacies, lack of local low-secure facilities and under-resourcing of community psychiatric services. Such barriers lead to inappropriate utilisation of limited resources and limit access to secure facilities for higher-risk mentally disordered offenders. These findings are of particular relevance in the context of proposed new insanity legislation.

The Short-Term Assessment of Risk and Treatability (START) is deemed the most appropriate instrument for assessing violence risks and management because of its balanced approach between dynamic risk and protective factors. Although several facets of reliability and predictive validity of this tool were strong, its inter-rater reliability, construct validity, and implementation in Asian population were under-investigated. The objective of this research was to examine the inter-rater reliability and construct validity of the START: Thai version within forensic psychiatric inpatients. The participants consisted of 118 forensic psychiatric inpatients hospitalized at Galya Rajanagarindra Institute in Thailand. Trained mental health professionals (i.e., psychiatrists, forensic nurses, clinical psychologists, social workers, and occupational therapists) assessed each participant across twenty domains of the Thai START. The inter-rater reliability was examined using the intraclass correlation coefficient and a confirmatory factor analysis for ordinal data was used to test the construct validity of the scale. The main finding showed a good-to-excellent inter-rater reliability and supported two relational constructs (i.e., strength vs vulnerability subscales) of the Thai START. The Thai START is a promising tool for using in Thai forensic psychiatric setting but some items were not significant in contributing to the scale. This study also provides the guideline for implementing the tool in non-Western forensic psychiatric populations.
