Challenging behaviours at early adulthood in autism spectrum disorders: topography, risk factors and evolution.

BACKGROUND: Challenging behaviours are highly prevalent in children and adolescents with autism spectrum disorders (ASD), but little is known about the prevalence and course of these behaviours during adulthood. The aims of this study were to describe the topography of challenging behaviours in a cohort of 106 young adults with ASD and to identify the risk factors for challenging behaviours. Our secondary objective was to study the changes in challenging behaviours from adolescence to early adult years. METHOD: The present study uses data from the EpiTED prospective follow-up study in France. The presence of challenging behaviours was assessed by the Aberrant Behaviour Checklist (ABC) completed by parent informants. Several dimensions of behaviour were studied: irritability, stereotypy, lethargy, hyperactivity and self-injury. Clinical variables were collected on ASD symptom severity, cognitive and language levels, adaptive behaviours and comorbid medical disorders. RESULTS: The presence of challenging behaviours at early adulthood was related to the young adult's cognitive and language level, ASD symptom severity and comorbid gastrointestinal and sleep disorders. The main risk factor for challenging behaviours was ASD symptom severity. The level of language impairment was a significant predictor of self-injury. Gastrointestinal disorders were a significant predictor of stereotypy. The change in behaviour topography from adolescence to early adult years corresponded with decreased parent report of hyperactivity, but no significant decrease in parent reports of irritability, stereotypy, lethargy and self-injurious behaviours. CONCLUSIONS: The challenging behaviours in individuals with ASD persist in early adulthood and are related to core symptom severity, levels of cognitive and language impairments and medical comorbidity. The results emphasise the importance of early interventions for children with ASD to target cognitive and language abilities and to alleviate the severity of ASD symptoms. They also underscore the need to enhance opportunities for individuals with ASD to better communicate discomforts and pain in the context of medical illness.

[Impact of anxiety disorders on quality of life of adolescents with autism spectrum disorder without intellectual disability]. / Impact des troubles anxieux sur la qualité de vie des adolescents avec un trouble du spectre autistique sans déficience intellectuelle.

INTRODUCTION: The prevalence of anxiety disorders has been recently estimated at 42 % in a population of adolescents with autism spectrum disorder without intellectual disability. This rate is more than two times higher than in adolescents without developmental disorders (around 20 %). Besides, according to recent studies, the quality of life of adolescents with ASD without mental retardation seems to be lower than adolescents with typical development. We guess that anxiety disorders may be responsible for a low quality of life in adolescents with ASD. OBJECTIVES: The aim of this study was to describe the relationship between quality of life and anxiety disorders. The first objective was to determine if anxiety disorders are a risk factor for having a low quality of life in adolescents with ASD. The second objective was to confirm this link with another comparison using a control group of adolescents with an anxiety disorder but without ASD. Our hypothesis was that anxiety disorder is a risk factor to decrease the quality of life of adolescents with ASD. METHODS: This research was a transversal descriptive and comparative study. Sixty-six adolescents aged between 11 and 18years old were included: 46 with ASD without mental retardation and 20 controls (with anxiety disorders without ASD). Among the ASD group, 20 patients were identified as having an anxiety disorder according to international classifications of mental diseases, and 26 adolescents had no psychiatric comorbidity. Quality of Life (QoL) was reported in five domains with the KIDSCREEN-27, for each patient in the three different groups. Diagnosis of anxiety disorders was assessed using the Kiddie-SADS-PL. The level of anxiety was measured with a self-report questionnaire (RC-MAS). We compared the anxiety rates and the QoL levels between the two groups of adolescents with ASD, one with anxiety disorders, the other without anxiety disorder. Comparisons were also made with QoL data from the general population. RESULTS: Quality of life in the two different groups of adolescents with ASD without mental retardation (with and without anxiety disorders) was significantly lower than in adolescents in the general population. Those rates were significantly lower in the group with ASD and anxiety disorders than in the group with ASD without anxiety disorders for the domain of "physical well-being" only. There was no significant difference between the groups regarding the four other domains of the Kidscreen-27. Moreover, there was no difference between adolescents with ASD and adolescents without ASD regarding the perceived level of anxiety. CONCLUSION: This study shows that anxiety disorders could be a risk factor for impairment of the "physical well-being" dimension of QoL in adolescents with ASD without intellectual disability. Results highlight the interest of a self-evaluation of anxiety level in a population of adolescents with ASD. Findings about self-report of QoL might be temper probably due to the insight difficulties that meet patients with ASD reported in literature review. Further research need to be done with larger samples of patients using self-evaluation coupled with hetero-evaluation such as parents' reports and clinicians' reports.

Symptom severity as a risk factor for self-injurious behaviours in adolescents with autism spectrum disorders.

BACKGROUND: Self-injurious behaviours (SIB) are highly prevalent in individuals with autism spectrum disorders (ASD) and have deleterious effects on the individual and their environment. The aim of this study was to examine SIB prevalence and associated features in a population of 152 adolescents with ASD and to determine risk factors for SIB. METHODS: The present study uses a subset of data of a longitudinal follow-up of 152 children with ASD. The presence of a low or high level of self-injury was assessed at adolescence through the Aberrant Behaviour Checklist completed by parents. Clinical and social variables regarding severity of autism symptoms, psychological development, adaptive behaviours, parental quality of life and total intervention time were collected during childhood (mean age = 5 years, SD = 1.6) and at adolescence (mean age = 15 years, SD = 1.3). RESULTS: About 35.8% of adolescents with ASD in our sample displayed self-injury, which was frequently associated with other challenging behaviours and was related to severity of autism symptoms, adaptive skills, intellectual functioning and language level (P < 0.001). The main risk factor for SIB at adolescence was severity of autism symptoms (P = 0.04). Cognitive development during childhood was found to be a protective factor (P = 0.03) whereas at adolescence, the main protective factor was communicative abilities (P = 0.04). CONCLUSIONS: These data showed that SIB remained highly prevalent at adolescence and yielded risk and protective factors for developing SIB at this period of life. Limitations and perspectives for future research are discussed.

[Implementation of a French cohort of children or adolescents with autism spectrum disorders: ELENA cohort]. / Mise en place d'une cohorte française d'enfants et adolescents présentant des troubles du spectre autistique : cohorte ELENA.

BACKGROUND: Multidisciplinary cohort studies of children with autism spectrum disorders (ASD) followed from childhood to adulthood exist abroad but not in France. The objective of the ELENA French cohort is to study the developmental trajectories of children and adolescents with ASD and their risk or protective associated factors. METHODS: This is an open, prospective and multicenter cohort study, including children and adolescents under 16 years of age with ASD recruited from services specialized in the assessment of developmental disorders. The patients will be monitored every 18 months for at least 36 months and during a maximum of 10 years. Clinical, social, environmental, and genetic data, as well as data relating to the parental quality of life will be collected. The primary endpoint will be the adaptive level in three domains of the Vineland II (communication, socialization and daily living skills). The secondary endpoints will be parental quality of life, comorbidities, interventions and severity of ASD. EXPECTED RESULTS AND PERSPECTIVES: The inclusion of 1600 patients over a 10-year period is expected. This cohort should contribute to a better knowledge of the child developing an ASD, taking into account the physical, social and familial environment, the type of interventions and some genetic components. It should also lay the foundations for a national network of professionals working in the field of autism research by offering them a common tool for promoting translational studies.

Social skills improvement in children with high-functioning autism: a pilot randomized controlled trial.

High-functioning autism (HFA) is characterized by persistent impairment in social interaction despite the absence of mental retardation. Although an increasing number of group-based programs for the improvement of social skills have been described, randomized controlled trials are needed to evaluate their efficacy. To compare the effect of a Social Skills Training Group-based Program (SST-GP) and a Leisure Activities Group-based Program (LA-GP) on the perception of facial emotions and quality of life (QoL) in young people with HFA. Eligible patients were children and adolescents with HFA. Participants were randomized to the SST or LA group. The primary outcome was defined as an improvement of 2 points in error rates for facial emotion labeling (DANVA2) from baseline. After the 6-month training period, the SST Group made fewer errors in labeling anger on adult faces, whereas error rates in the LA Group remained stable. Progress in the ability to recognize anger in the SST Group was due to better recognition of low intensity stimuli on adult faces. QoL increased in the SST Group in the dimension of school environment, as a marker of the transfer of skills acquired in the treatment setting to their use in the community. The SST-GP had higher efficacy than the LA-GP. Data justify replication using larger samples.

[Infants and toddlers behavioral and functional disorders: characteristics, mother-child interactions, alliance and outcome after a brief parents-child psychotherapy. A pilot study]. / Troubles du comportement et troubles fonctionnels du nourrisson : caractéristiques, interactions mère-enfant, alliance et évolution après une psychothérapie brève parent-enfant. Étude pilote.

OBJECTIVES: Functional and behavioral disorders are the most frequent reasons for consultation in infant psychiatry, but there are still few studies about the efficacy of parents-child psychotherapies. Functional disorders appear to be easier to treat than behavioral disorders. The aim of this study was: (1) to assess outcome after a brief psychotherapy in a population of 49 infants aged 3 to 30 months, presenting functional or behavioral disorders; (2) to compare characteristics before therapy and outcomes for children with functional disorders and with behavioral disorders, to have a better understanding of the worse outcome of children with behavioral disorders. METHODS: Two assessments were performed, one before treatment and the second a month after the end of the therapy including the infant's symptoms (Symptom Check-list), parents' anxious and depressive symptoms (Hospital Anxiety and Depression scale) and mother-infant interactions (Crittenden Experimental Index of adult-infant relationship). The therapeutic alliance was assessed by the therapist and the parents after the first consultation (Working Alliance Inventory). RESULTS: The assessments after therapy show complete or partial improvement in the child's symptoms, in the mother's anxious and depressive symptoms and in the father's anxious symptoms. During interaction, the mothers become more sensible, the number of controlling and of unresponsive mothers decrease, while the children become more cooperative and less passive. Initial characteristics and outcome are however different according to the type of the child's disorder. The children with behavioral disorders are older and present an association of several symptoms. The disorder onset is later. Their mothers are, before therapy, more anxious and depressive. The therapeutic alliance is weaker. After therapy, despite the fact that their mothers' affective state and that interactive behavior improves, the mothers are more anxious and less sensible, while the children no longer differ from the group without behavioral disorder from the point of view of opposition (assessed during mother-child interaction). CONCLUSION: Although this study is limited by the lack of a control group and the sample size, it underlines some particularities of infants and toddlers presenting behavioral disorders and the difficulties involved in their treatment. One can wonder if these characteristics are specific of the behavioral disorders or if they are the result of an older dysfunction, complicated by the developmental evolution of the child and the duration of the difficulties. The small number of cases, among the children with behavioral disorders, presenting a preexistent functional disorder, the absence of difference in the duration of the disorders, and the different disorder's onset plead in favor of the first hypothesis. The behavioral disorders often associate child psychopathology, dysfunctional parents-child-relationships and environmental factors difficult to modify with a brief therapy focused on the relationship. It would appear necessary to develop specific treatments for this population.

Predictors of outcome in infant and toddlers functional or behavioral disorders after a brief parent-infant psychotherapy.

The efficacy of parent-child psychotherapies is widely recognized today. There are, however, less data on predictive factors for outcome in infants and toddlers and their parents. The aim of this study was to highlight predictive factors for outcome after a brief psychotherapy in a population of 49 infants and toddlers aged 3-30 months presenting functional or behavioral disorders. Two assessments were performed, the first before treatment and the second a month after the end of the therapy. These assessments included an evaluation of the child's symptoms, and of depressive or anxiety symptoms in the parents. The assessments after therapy show complete or partial improvement in the child's symptoms for nearly three quarters, and a decrease in the number of anxious and depressive mothers, and also in the number of depressive fathers. Three independent factors appear as predictive of unfavorable outcome for the child: frequency and intensity of behavioral problems and fears, and the absence of the father at more than two-thirds of consultations. The outcome for the mother is associated solely with her anxiety score at the start of the therapy. This study underlines the particular difficulties involved in the treatment of infants and toddlers presenting behavioral disturbances and emotional difficulties, and the value of involving the father in treatment.

Daily living pain assessment in children with autism: Exploratory study.

This study aims to broaden knowledge about pain expression and assessment in daily life situations in children with Autism Spectrum Disorder (ASD). The goals are to provide a description of the responses of the GED-DI, the French version of the NCCPC, and to test the internal structure validity of this scale. Thirty five children with ASD were included in this study (mean age=58months; mean developmental age=32months). The French version of the NCCPC was filled in by parents. Descriptive analysis of responses shows that children with ASD express pain through varied and common behaviours, related to different expressive markers (vocal, facial, activity, etc.). Behaviours more specific to the symptomology and disturbances of ASD are also displayed. A four-factor solution (negative emotional reaction, idiosyncratic expression, hyper-vigilance reaction, pain expression) emerges from an exploratory factor analysis that explains 54.4% of the total variance. Correlation coefficients show good psychometric qualities in terms of internal consistency, factorial validity and discriminant validity. This study provides new data about pain expression in daily life situations and shows that the French version of NCCPC adjusted to ASD children is relevant to assess pain in daily life situations.
