Predictors of Self-Injurious Behavior and Self-Restraint in Autism Spectrum Disorder: Towards a Hypothesis of Impaired Behavioral Control / Caroline RICHARDS in Journal of Autism and Developmental Disorders, 47-3 (March 2017)
[article]
Titre : Predictors of Self-Injurious Behavior and Self-Restraint in Autism Spectrum Disorder: Towards a Hypothesis of Impaired Behavioral Control Type de document : Texte imprimé et/ou numérique Auteurs : Caroline RICHARDS, Auteur ; Louise DAVIES, Auteur ; Chris OLIVER, Auteur Article en page(s) : p.701-713 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Self-injury Self-restraint Prevalence Impulsivity Pain Index. décimale : PER Périodiques Résumé : Self-injury is common in autism spectrum disorder (ASD); however few studies have investigated correlates of self-injury or the putative associations with self-restraint. Questionnaire data on self-injury, self-restraint, health conditions, overactivity/impulsivity and repetitive/restricted behavior were collected on 208 children and 216 adults with ASD (mean age?=?24.10, range 6–61). Self-injury and self-restraint were frequent and significantly associated in both children (45.7% and 40.9%, p?0.001) and adults (49.1, and 42.6%, p?0.001). Severe self-injury was predicted by lower ability, health conditions and overactivity/impulsivity in children (p?0.001) and repetitive/restricted behavior and overactivity/impulsivity in adults (p?0.001). These data provide preliminary support for a developmental model of self-injury and self-restraint in which painful health conditions and compromised behavioral control influence the presence and trajectory of self-injury in ASD.

Titre : Persistence and predictors of self-injurious behaviour in autism: a ten-year prospective cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Catherine LAVERTY, Auteur ; Chris OLIVER, Auteur ; Jo MOSS, Auteur ; Lisa NELSON, Auteur ; Caroline RICHARDS, Auteur Article en page(s) : 8 p. Langues : Anglais (eng) Mots-clés : Autism Impulsivity Prevalence Risk marker Self-injury Self-restraint Index. décimale : PER Périodiques Résumé : BACKGROUND: Self-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. METHODS: Carers of 67 individuals with autism completed questionnaires relating to the presence of self-injury and relevant risk markers at T (1) (mean [SD] age in years 13.4 [7.7]) and T (3) (mean [SD] age in years 23.9 [7.7]) 10?years later. Forty-six of these also took part at T (2) (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 T (1)and T (2.) RESULTS: Self-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. CONCLUSIONS: In 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.
