Self-injurious behaviour in forensic mental health care: a study into the prevalence and characteristics of incidents of self-injury

PurposeIncidents of self-injury by forensic psychiatric patients often have a deleterious impact on all those involved. Moreover, self-injurious behaviour is an important predictor for violence towards others during treatment. The aim of this study is to analyse methods and severity of incidents of self-injury of patients admitted to forensic psychiatry, as well as the diagnoses of self-injuring patients.Design/methodology/approachAll incidents of self-injury during treatment in a forensic psychiatric centre recorded between 2008 and 2019 were analysed and the severity was coded with the modified observed aggression scale+ (MOAS+).FindingsIn this period, 299 incidents of self-injury were recorded, displayed by 106 patients. Most of these incidents (87.6%) were classified as non-suicidal. Methods most often used were skin cutting with glass, broken plates, a razor or knife and swallowing dangerous objects or liquids. Ten patients died by suicide, almost all by suffocation with a rope or belt. The majority of the incidents was coded as severe or extreme with the MOAS+. Female patients were overrepresented and they caused on average three times more incidents than male patients.Practical implicationsMore attention is warranted for self-injurious behaviour during forensic treatment considering the distressing consequences for both patients themselves, supervisors and witnesses. Adequate screening for risk of self-injurious behaviour could help to prevent this behaviour. Further research is needed in different forensic settings into predictors of self-injurious behaviour, more specifically, if there are distinct predictors for aggression to others versus to the self.Originality/valueIncidents of self-injury occur with some regularity in forensic mental health care and are usually classified as severe. The impact of suicide (attempts) and incidents of self-injurious behaviour on all those involved can be enormous. More research is needed into the impact on all those involved, motivations, precipitants and functions of self-injurious behaviour and effective treatment of it.

Brief Report: Associations Between Self-injurious Behaviors and Abdominal Pain Among Individuals with ASD-Associated Disruptive Mutations.

Self-injurious behaviors (SIB) are elevated in autism spectrum disorder (ASD) and related genetic disorders, but the genetic and biological mechanisms that contribute to SIB in ASD are poorly understood. This study examined rates and predictors of SIB in 112 individuals with disruptive mutations to ASD-risk genes. Current SIB were reported in 30% of participants and associated with poorer cognitive and adaptive skills. History of severe abdominal pain predicted higher rates of SIB and SIB severity after controlling for age and adaptive behavior; individuals with a history of severe abdominal pain were eight times more likely to exhibit SIB than those with no history. Future research is needed to examine associations between genetic risk, pain, and SIB in this population.

Persistence and predictors of self-injurious behaviour in autism: a ten-year prospective cohort study

BackgroundSelf-injurious behaviours, such as head banging, hair pulling, skin picking and scratching, are common in individuals with autism. Despite high prevalence rates, there is a paucity of longitudinal research to refine models of risk and mechanism and inform service planning. In this longitudinal study, we investigated self-injury in a cohort of individuals with autism over 10 years to identify behavioural and demographic characteristics associated with persistent self-injury.MethodsCarers of 67 individuals with autism completed questionnaires relating to the presence of self-injury and relevant risk markers at T1 (mean [SD] age in years 13.4 [7.7]) and T3 (mean [SD] age in years 23.9 [7.7]) 10 years later. Forty-six of these also took part at T2 (3 years after initial participation). Analysis assessed demographic and behavioural risk markers for self-injury, as well as the predictive value of items assessed at T1and T2.ResultsSelf-injury was persistent in 44% of individuals over the 10-year period, with behavioural characteristics of impulsivity (p < .001) and overactivity (p = .002), identified as risk markers for persistence. A predictive model of self-injury was derived from LASSO analysis, with baseline impulsivity, interest and pleasure, stereotyped behaviour, social communication and adaptive functioning predicting self-injury over 10 years.ConclusionsIn this unique longitudinal investigation into the persistence of self-injury in a non-clinical sample of individuals with autism over a 10 year period, we have identified a novel, robust and stable profile of behavioural characteristics associated with persistent self-injury. Findings support an early intervention strategy targeted towards individuals identified to be at a higher risk of developing self-injurious behaviour.
