Persistence and predictors of self-injurious behaviour in autism: a ten-year prospective cohort study / Catherine LAVERTY in Molecular Autism, 11 (2020)
[article]
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.

[article]
Titre : Practitioner Review: Self-injurious behaviour in children with developmental delay Type de document : Texte imprimé et/ou numérique Auteurs : Chris OLIVER, Auteur ; Caroline RICHARDS, Auteur Article en page(s) : p.1042-1054 Langues : Anglais (eng) Mots-clés : Self-injury applied behaviour analysis autism spectrum disorder genetic syndrome behavioural phenotype behaviour dysregulation intellectual disability Index. décimale : PER Périodiques Résumé : Background Self-injurious behaviour is shown by a significant minority of children with developmental delay and has a substantial impact on child and carer wellbeing. Characteristics such as a greater degree of intellectual disability, autism spectrum disorder, some genetic syndromes and repetitive and impulsive behaviours are positively associated with self-injury. Prevalence generally increases with age into midadulthood and the behaviour is notably persistent. Scope In this review, we discuss the dominant causal theory of self-injury which draws on the principles of operant learning. We evaluate the utility of this theory to account for all empirical observations of self-injury. Findings A model of self-injury is presented that extends a previous model described by Guess and Carr. The new model integrates child characteristics and operant learning principles in a phenotype × environment paradigm to explain the variance in developmental trajectory of the severity of self-injury. Conclusions Behaviour dysregulation, as evidenced by the associations between self-injury, self-restraint, repetitive and impulsive behaviours, is identified as potentially influencing the severity and persistence of self-injury. Risk markers for self-injury are identified and the extended model indicates points of intervention and highlights the possibility of risk-related, targeted early intervention. The need for increased training of practitioners in the delivery of demonstrably effective interventions for self-injury is identified.

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.

This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n?=?83) completed questionnaires regarding the presence/topography of self-harm, demographic characteristics, autism severity, age of diagnosis, affect, activity levels and repetitive behaviour. 24.10% of participants engaged in self-harm. Self-harm was associated with significantly higher levels of impulsivity, over-activity, negative affect, compulsive behaviour and insistence on sameness. Low mood and overactivity/impulsivity predicted the presence of self-harm, with the model correctly classifying 82.9% of cases. Findings highlight a role for impaired behavioural inhibition and low mood in the aetiological mechanisms underpinning self-harm in autism.

Titre : Prevalence of autism spectrum disorder symptomatology and related behavioural characteristics in individuals with Down syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Jo MOSS, Auteur ; Caroline RICHARDS, Auteur ; Lisa NELSON, Auteur ; Chris OLIVER, Auteur Article en page(s) : p.390-404 Langues : Anglais (eng) Mots-clés : Down syndrome autism spectrum disorder repetitive behaviour challenging behaviour mood behavioural phenotype Index. décimale : PER Périodiques Résumé : We evaluated the proportion of individuals with Down syndrome (DS: N = 108) who met criteria for autism spectrum disorder (ASD) on the Social Communication Questionnaire and the severity of ASD-related symptomatology in this group. The proportions of individuals with DS meeting the cut-off for ASD and autism in this sample were 19% and 8%, respectively. We then evaluated the behavioural profile of individuals with DS who scored above cut-off for ASD (DS+ASD; N = 17) compared with those with DS-only (N = 17) and individuals with idiopathic ASD (N = 17), matched for adaptive behaviour skills and ASD symptom severity (ASD group only). Individuals in the DS+ASD and ASD-only groups showed more stereotyped behaviour, repetitive language, overactivity and self-injury than the DS-only group (p .001). Individuals in the DS+ASD and DS-only groups appeared less withdrawn from their surroundings than those with ASD (p .004). These findings indicate differences in the behavioural and cognitive profile of individuals with DS+ASD compared with those with DS-only, when controlling for adaptive behaviour skills. Individuals with DS+ASD show broad similarities with individuals with idiopathic ASD with regard to ASD and behavioural characteristics but may also show some areas of subtle difference from this group.
