Autism spectrum disorder (ASD) is a complex neurodevelopmental condition influenced by a myriad of developmental, biological, psychological, and socio-demographic factors. The ELENA cohort seeks to delineate the intricate interplay of these factors, facilitating the identification of risk factors and the development of targeted interventions. This paper emphasizes the clinical profiles of children and outlines key findings from a biopsychosocial perspective. The ELENA cohort, a multicenter initiative across French regional centers, conducted a systematic prospective analysis on children newly diagnosed with DSM-5 ASD between 2012 and 2019. This encompassed direct assessments and parent-reported questionnaires covering a broad spectrum of developmental, biological, psychological and socio-demographic measures. Embedded case-control studies further examined risk and protective factors, alongside specific environmental and psychosocial influences during pregnancy and early childhood. A subset of participants also contributed biospecimens, with data enhancement via linkage to French National Administrative Healthcare Databases. The study unveils baseline clinical characteristics for 876 children, average age 6 (SD ± 3.3) previously unreported in protocol descriptions. It highlights the study's developmental biopsychosocial approach and its novel findings on children's socio-adaptive functioning, ASD severity, comorbidities, quality of life and interventions. Employing developmental biopsychosocial insights offers a promising pathway to integrating health, social care, and experiential insights, ultimately aiming to enhance the future well-being and outcomes for children with ASD. This approach underscores the need of a holistic, interdisciplinary strategy in encouraging and supporting the ASD community., (© 2024.

Objectives: Autism spectrum disorder (ASD) has a major impact on caregivers. We aimed to describe caregivers' perceptions concerning their level of knowledge about ASD and their needs to better adapt education and training programs., Methods: This was a descriptive cross-sectional study conducted through a declarative and self-administered survey in France., Results: 1,013 individuals answered the questionnaire in 2020. If most caregivers felt they had sufficient knowledge about ASD, they still expressed a high level of needs regarding acquiring knowledge, identifying available resources, and finding social/emotional support., Conclusions: This study highlights the high level of needs of caregivers and their expectations of improving their knowledge and skills to help the person with ASD., (© 2022.

Background: ASD in a child affects parental mental health, with elevated levels of stress, anxiety and depression reported in parents., Method: In this study, we examined mothers' and fathers' stress, anxiety and depression, as well as their coping strategies in a sample of 103 children and adolescents enrolled in the ELENA cohort study in France at diagnosis and three years after diagnosis., Results: Results showed that mothers had higher levels of stress and anxiety / depression than fathers and used more social support coping strategies at diagnosis, which might be explained by increased levels of parental involvement. Mothers' stress level significantly decreased during the three years following ASD diagnosis but no such decrease was observed in fathers' stress level. A significant decrease in anxiety and depression was observed for both parents, suggesting that parental distress is particularly elevated during the critical diagnosis period. Results finally yielded a significant decrease in emotion-focused coping strategy in mothers over the three-year period, an ineffective strategy that takes places at the time of diagnosis but then decreases during the period following ASD diagnosis, in relation to the acceptance process., Conclusions: Implications in terms of addressing the unmet mental health needs of parents and their coping strategies are discussed., Competing Interests: Conflicts of Interest None., (Copyright © 2023 Elsevier Ltd.

Introduction: The elevated rates of neurodevelopmental disorders (NDDs) among siblings of children with autism spectrum disorder (ASD) raise concerns about their developmental monitoring and development. The main aim of this study is to assess the feasibility and acceptability of a standardised screening process on a large sample of siblings., Methods and Analysis: This prospective study will assess the feasibility of a selective and multi-stage screening process for NDD performed on 384 siblings of children with confirmed ASD. Stage 1 will consist of the screening of NDD performed using online parental questionnaires (Social Responsiveness Scale, IdentiDys scale, DCDQ, parental concerns) through a web platform. In cases of a positive result, the second stage, consisting of a clinical semi-structured interview with a psychologist, will be proposed to the sibling before referral for diagnosis and treatment, if necessary. Approximately 12 months after stage 2, parents will be contacted by telephone to collect the diagnosis established following the referrals and their level of satisfaction concerning the screening process. Based on an expected participation rate of 50%, to estimate this rate with an accuracy of 5%, it is necessary to screen 384 subjects., Ethics and Dissemination: The Ethics Committee on the Research of Human Subjects of Paris (Ile de France VII) approved this study in March 2022 (number: 2021-A02241-40). Express consent is required from all participants. Findings from the cohort study will be disseminated by publication of peer-reviewed manuscripts, presentations at scientific meetings and conferences with associated teams., Trial Registration Number: NCT05512637., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Autism spectrum disorder (ASD) has a significant impact on the quality of life (QoL) of families. This study aimed to examine, for parents of children with ASD, the dyadic effect of each parent's coping strategy on the perception of the impact of ASD on their QoL. In total, 164 couples completed self-report questionnaires, including the Par-DD-QoL, to evaluate the parental perception of QoL. Results from the actor-partner interdependence model showed that, in addition to the effect of the mothers' and fathers' emotion-focused coping on their own perception of QoL, the mothers' emotion-focused coping plays a key role in the fathers' perception of QoL. These findings suggest that both parents of children with ASD would benefit from couple-focused interventions., (© 2022.

Objective: The literature on sex related-clinical differences for children with autism spectrum disorder (ASD) is highly contradictory, whereas this topic has major clinical implications. We aimed to investigate sex-related clinical differences in children with ASD without intellectual disability (ID)., Materials and Methods: We compared 319 boys and 65 girls with ASD without ID, aged from 2 to 12 years, recruited from a multiregional cohort on their clinical profiles based on the scores for the Vineland-II, the SRS-2, the ADOS calibrated severity score, sensory processing, aberrant behaviors, and comorbidity rates., Results: Our results confirm a high sex ratio of 4.9 males/females. Many similarities were found in the clinical profiles. However, we found that girls had higher SRS-2 total scores. In addition, there was a negative correlation between the SRS-2 total score and the intellectual quotient level (IQ) for girls only., Conclusion: We confirm the higher rates of boys with ASD without ID. A comparison between the girls and boys showed them to have similar clinical profiles, except for the SRS- 2 total scores, which were higher among girls, suggesting more severe social impairment perceived by parents. Our findings that the cognitive level is related to ASD severity in girls should be taken into account during the diagnostic procedure in the clinical interpretation of gold-standard measures of ASD, and additional clinical observations are necessary., Clinical Trial Registration: [ClinicalTrials.gov], identifier [NCT02625116s]., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Dellapiazza, Michelon, Rattaz, Picot and Baghdadli.)

Lay Abstract: Autism spectrum disorder is an early onset neurodevelopmental disorder and diagnosis can be made as early as 18 months of age. Early diagnosis of autism spectrum disorder is critical as it leads to early intervention. Age of autism spectrum disorder diagnosis has been linked to the child profile as autism spectrum disorder is characterized by strong heterogeneity, but is also influenced by socio-economic factors. There is paucity of data on age of diagnosis of autism spectrum disorder in France. We therefore examined the age of autism spectrum disorder diagnosis in 554 children and adolescents enrolled in the ELENA cohort study with respect to the influences of child profile, family antecedents, and socio-economic factors. The mean age of diagnosis was 4.9 years (±2.8 years). Early diagnosis, before 3 years of age, was related to the co-occurrence of intellectual disability, higher autism spectrum disorder symptom severity, and lower communicative abilities. Children in low socio-economic status families tended to have an earlier diagnosis, but these children also had greater degree of intellectual impairment compared to children in high socio-economic status families. The age of autism spectrum disorder diagnosis was not associated with the presence of an older sibling with autism spectrum disorder. The observed current trend of an inverse relationship between socio-economic status and age of diagnosis of autism spectrum disorder suggests equitable access to autism spectrum disorder services in France where health coverage is universal and free. Better screening of more subtle/less severe forms of autism spectrum disorder is needed, as well as further assessment of the link between the co-occurrence of autism spectrum disorder and intellectual impairment in children in lower socio-economic status families.

Objective: Autism Spectrum Disorder (ASD) is a chronic neurodevelopmental disorder. Living with ASD requires that individuals and parents develop skills in order to cope with daily life. Education interventions are recommended to support them. This study aims to get an overview of education and training interventions in ASD., Methods: A scoping review of international literature was conducted., Results: 43 articles were analyzed. Four main types of intervention stand out: support groups, parental training; psychoeducation; therapeutic patient education. However, the majority of publications is focused on the parents rather than on individuals living with ASD, and the needs assessments identified focused on general needs rather than educational needs., Conclusion: While educational interventions for parents and individuals with ASD are now encouraged, considerable heterogeneity is observed. But this variety is not based on a reasoned approach to matching supply and needs. Future studies could focus more on the educational needs of individuals with ASD., Practice Implications: Overview of education and training interventions in ASD help health care providers to better understand the strengths and limitations of their interventions., (Copyright © 2022 Elsevier B.V.

Purpose: To compare mothers and fathers perceptions of the impact of autism spectrum disorder on their Quality of Life (QoL), we used the Parental-Developmental Disorders-Quality of Life scale (Par-DD-QoL)., Method: The perception of QoL of mothers and fathers was compared for 130 pairs of parents of children with ASD and the associated variables were investigated., Results: Mothers perceived a significantly greater impact of ASD on their QoL than fathers. Parents perceived a higher impact of ASD on global QoL when their child's adaptive skills were low and when the level of aberrant behaviors was high. More precisely, the perception of QoL by the mothers was negatively associated with their child's internalized disorders, whereas the perception of QoL by the fathers was negatively associated with their child's externalized disorders. Neither the mothers' nor the fathers' perception of the impact on QoL was associated with their children's age or the severity of their autistic symptoms. Some parental factors, such as being members of a family association, having benefited from training in ASD and having experienced a disruption in professional activity were associated with a greater impact on their QoL., Conclusion: Our finding that the perceived impact of ASD on QoL differed between mothers and fathers argues for individualized psychosocial support. Moreover, the strong correlation between the child's clinical characteristics and the perception by parents of a higher impact of ASD on QoL should be seen as red flag concerning the needs of the parents in terms of social and educational support., Trial Registration Number: NCT02625116 (October 2015)., (© 2021.

Background: Containment, involving separation and restriction of movement of people due to the COVID-19 pandemic, and mitigation, also referred to as lockdown, involving closure of schools, universities and public venues, has had a profound impact on people's lives globally. The study focuses on the effects of containment and mitigation measures, on the behavior of children and youth (CaY) with Autism Spectrum Disorders (ASD). The study primary aim was to examine the impact of these urgent measures on the behaviors, communication, sleep, and nutritional status of the CaY. A secondary aim was to explore risk and protective factors on behavior change including sociodemographic variables, living conditions, ASD symptom severity and continuity of interventions., Methods: The study sample consisted of 239 ASD subjects, 2-21 years of age, enrolled in the ELENA cohort in France at Stage 3 confinement and mitigation measures announced on March 16, 2020. A parent informant completed the COVID-19 questionnaire., Results: Of the domains examined, challenging behaviors, communicative skills and sleep had the greatest impact; in terms of risk and protective factors, subject age, ASD severity, single parenthood, daily living skills, and intervention continuity were most likely to impact behaviors; living conditions were not linked to behavior change., Conclusions: The findings highlight the topography of behavioral change in CaY with ASD following institution of containment and mitigation measures during the COVID-19 pandemic and help identify risk and protective factors to help better address needs and tailor interventions in the future., (Copyright © 2021 Elsevier Ltd.

Children and adolescents with ASD are increasingly included in regular school settings, however little is known about how placement decisions are made. In the present study, we examined the types and duration of school attendance among children and adolescents in the ELENA Cohort, a multi-center study of children and adolescents with ASD, ages 2-16 years, in France. Results showed that 88% of subjects were attending school and that children and adolescents with more severe adaptive and cognitive deficits were less likely to attend school. The results provide a topography on school inclusion and ASD in France. Challenging behaviors and sensory processing difficulties were associated with partial-inclusion; and co-occurring anxiety symptoms were associated with inclusion on a full-time basis.

Introduction: There is global concern about the increasing prevalence of autism spectrum disorders (ASDs), which are early-onset and long-lasting disorders. Although ASDs are considered to comprise a unique syndrome, their clinical presentation and outcome vary widely. Large-scale and long-term cohort studies of well-phenotyped samples are needed to better understand the course of ASDs and their determinants. The primary objective of the multicEntric Longitudinal study of childrEN with ASD (ELENA) study is to understand the natural history of ASD in children and identify the risk and prognostic factors that affect their health and development., Methods and Analysis: This is a multicentric, longitudinal, prospective, observational cohort in which 1000 children with ASD diagnosed between 2 and 16 years of age will be recruited by 2020 and followed over 6 years. The baseline follow-up starts with the clinical examination to establish the ASD diagnosis. A battery of clinical tools consisting of the Autism Diagnostic Observation Schedule, the revised version of the Autism Diagnostic Interview, measures of intellectual functioning, as well as large-scale behavioural and developmental measurements will allow us to study the heterogeneity of the clinical presentation of ASD subtypes. Subsequent follow-up at 18 months and at 3, 4.5 and 6 years after the baseline examination will allow us to explore the developmental trajectories and variables associated with the severity of ASD. In addition to the children's clinical and developmental examinations, parents are invited to complete self-reported questionnaires concerning perinatal and early postnatal history, congenital anomalies, genetic factors, lifestyle factors, medical and psychiatric comorbidities, and the socioeconomic environment. As of 1 November 2018, a total of 766 participants have been included., Ethics and Dissemination: Ethical approval was obtained through the Marseille Mediterranean Ethics Committee (ID RCB: 2014-A01423-44), France. We aim to disseminate the findings through national and international conferences, international peer-reviewed journals, and social media., Trial Registration Number: NCT02625116; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

There is limited data on long-term outcome of ASD with co-occurring intellectual disabilities (ID) and challenging behaviours in France. The EpiTED period cohort is a 15 years longitudinal study of the developmental trajectories of 281 children initially recruited at mean age of 5 years. Two contrasted developmental trajectories were identified. Low cognitive level, absence of language, and higher ASD scores at baseline were predictive of low growth at follow-up. As adults the participants were predisposed to persistent co-occurring challenging behaviours as well as underlying ID impacting their ability to function independently. The results underscore the need for development of services and supports for adults with ASD in France who may also have already lacked access to adequate interventions and support services.

Little is known about long-term outcomes. We investigate the adaptive trajectories and their risk factors in ASD. Data were obtained from 281 children prospectively followed untill adulthood. The final sample consisted of 106 individuals. Vineland scores were collected at baseline (T1), 3 (T2), 10 (T3), and 15 (T4) years later. A group-based method was used to identify homogeneous patterns of adaptive skills trajectories. Results show that among the children initially categorized as autistic, 82.6% remained over the ADOS diagnostic threshold, 11.9% converted to atypical autism, and 5.4% fell under the ADOS threshold. Most atypical autism diagnoses were unstable. Most (81.7%) autistic participants had an ID at inclusion. At T1, 59.3% were nonverbal, but only 39% at T4. Most changes occurred between 4 and 8 years of age. Approximately 25% of participants exhibited a "high" growth trajectory, in which progress continues throughout adolescence, and 75% a "low" growth trajectory, characterized by greater autistic symptoms, intellectual disability, and lower language abilities reflected by high CARS scores, low apparent DQ, and speech difficulties, which mostly, but not always, predicted low trajectories. Our findings suggest that the adaptive prognosis of autism is mostly poor in this cohort, biased toward intellectual disability. However, changes in diagnostic, speech, and adaptive status are not uncommon, even for indivduals with low measured intelligence or apparent intellectual disability, and are sometimes difficult to predict.

LAY SUMMARY: Most autism diagnoses given before 5 years of age are stable to adulthood, but one-fifth of individuals are no longer considered to be autistic, even in a cohort biased toward apparent intellectual disability. Conversely, atypical autism diagnoses are mostly unstable. One-third of children who are nonverbal at 5 years are verbal within 15 years, mostly before 8 years of age. Concerning adaptive behavior outcomes, only one-fourth of children exhibit a high-growth trajectory through at least 15 years., (© 2018 International Society for Autism Research, Wiley Periodicals, Inc.)

The impact of ASD on parental QOL was evaluated in the EpiTED cohort study at early adulthood. Two-third of parents of young adults with ASD (66.7%) reported that their QoL was at least moderately altered. The perceived impact of ASD on parental QoL was related to the young adults' level of adaptive skills, as well as to symptom severity and the presence of challenging behaviors, which appeared to be the main risk factor. The study of change between adolescence and early adulthood showed that parents whose children had a decrease in challenging behaviors perceived a decreased impact on their QoL. These results argue for the importance to propose specific interventions to target associated challenging behaviors in ASD.

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., (Copyright © 2016.

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., (Copyright © 2014 Elsevier Masson SAS.

Purpose: To study the impact of autism spectrum disorders (ASDs) on parental quality of life (QoL) at adolescence using the parental-developmental disorders-quality of life scale (Par-DD-QoL)., Methods: One hundred and fifty-two mothers of adolescents with ASD completed Par-DD-QoL. This scale assesses the following dimensions: emotional, daily disturbance and global QoL. This cross-sectional study uses a subset of data collected at the final time of a follow-up study (EpiTED cohort)., Results: A polytomic regression identified an increase in aberrant behavior scores as the major independent risk factor for parental QoL. The identified protective factors were the increase in daily living, communication and object cognition scores and a higher number of siblings., Conclusions: Those results suggest that there is a negative effect of externalizing behaviors and a protective effect of adaptive skills, communication and object cognition on parental QoL. Study limitations and implications are discussed.

This study focused on parents' satisfaction with the special education and care services proposed to their child with autism spectrum disorders (ASD). Data were collected in three regions of France, using a questionnaire designed for the purpose of this study. Among the 530 families contacted, 212 filled in the questionnaire (response rate = 40.8%). Results showed that parents were globally satisfied with providers' involvement and motivation, but they felt they were not involved enough in their child's individualized program, that communication with providers was insufficient and that the services lacked ASD's specific tools and interventions. Among all families interviewed, parents of adolescents were the most unsatisfied and we hypothesized that this could be due to the specific issues regarding developmental changes and concern about the future at this period of life. Congruently with the literature, variables related to parental overall satisfaction were a regular communication with professionals, a specific, regularly updated individual program in which parents are associated, and specialized tools and interventions. The implications of these findings are discussed as well as future directions for clinicians to improve service delivery and allow the persons with ASD and their families to be more involved in the services.

There is a lack of knowledge about pain reactions in children with autism spectrum disorders (ASD), who have often been considered as insensitive to pain. The objective of this study was to describe the facial, behavioral and physiological reactions of children with ASD during venipuncture and to compare them to the reactions of children with an intellectual disability and nonimpaired control children. We also examined the relation between developmental age and pain reactions. The sample included 35 children with ASD, 32 children with an intellectual disability, and 36 nonimpaired children. The children were videotaped during venipuncture and their heart rate was recorded. Facial reactions were assessed using the Child Facial Coding System (CFCS) and behavioral reactions were scored using the Noncommunicating Children's Pain Checklist (NCCPC). A linear mixed-effects model showed that children's reactions increased between baseline and venipuncture and decreased between the end of venipuncture and the recovery period. There was no significant difference between groups regarding the amount of facial, behavioral and physiological reactions. However, behavioral reactions seemed to remain high in children with ASD after the end of the venipuncture, in contrast with children in the 2 other groups. Moreover, we observed a significant decrease in pain expression with age in nonimpaired children, but no such effect was found regarding children with ASD. The data reveal that children with ASD displayed a significant pain reaction in this situation and tend to recover more slowly after the painful experience. Improvement in pain assessment and management in this population is necessary., (Copyright © 2013 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.)

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., (Copyright © 2012 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)

The purpose of the present article was to assess the available literature concerning pain and autism. First, authors summarized the published articles on pain reactivity in people with autism. Second, the hypotheses envisaged to explain the presence of expressive particularities in people with autism spectrum disorders were reviewed; these included endogenous opioid excess theory, sensorial abnormalities and sociocommunicative deficit. Finally, the present review dealt with the tools available to assess and manage pain in people with autism. In conclusion, the authors revealed the need for more research to obtain more consensual data and provided some recommendations in this domain that were under exploited by the scientific community. From a clinical point of view, more knowledge about pain in people with autism should enable the development of specific assessment tools and, consequently, better pain management in daily care.
