Psychometric properties of the French Infant-Toddler Working Alliance Inventory Short version (IT-WAI-S).

OBJECTIVE: Therapeutic alliance has been little investigated in infant and toddler therapy, with no tools specifically adapted to this population. However, we have developed the Infant-Toddler Working Alliance Inventory-Short form (IT-WAI-S) which is based on the Working Alliance Inventory. The aim of this study was to assess the psychometric properties of this original French tool, in its two versions: for parent (IT-WAI-SP) and for therapist (IT-WAI-STh). METHOD: This study included 227 families consulting with their 18-48-month-old child for emotional or behavioral disorders. The scales were filled in at the first three therapy sessions. The IT-WAI-S acceptability, internal validity, reliability and predictive validity (association with child and mother's outcomes) were evaluated. RESULTS: Confirmatory then exploratory factor analyses revealed a three-factor structure for the both scales: Negative Experience of Care Relationship, Positive Alliance and Alliance with the Child. Acceptability, reproducibility and construct validity were satisfactory for both versions. The two versions predicted the child's outcome. The IT-WAI-SP predicted also the mother's outcome. The IT-WAI-STh gave more reproducible results, whereas the IT-WAI-SP was a better predictor of the child's progress. CONCLUSION: The two IT-WAI-S versions showed good psychometric properties and could be used to study the therapeutic alliance in young children.

Predictive factors for the outcome of emotional and/or behavioural disorders in 18- to 48-month-old children after parent-child psychotherapy: Protocol of a European prospective cohort study.

OBJECTIVES: Several studies have shown that in young children, behavioural and/or emotional disorders are more difficult to manage than regulatory disorders. Moreover, data are lacking on outcome predictive factors. This article presents a short synthesis of previous research about outcome predictive factors in child psychiatry. It also describes the protocol of a longitudinal observational European multicentre study the main objective of which was to identify predictive factors of behavioural and emotional disorder outcome in toddlers after parent-child psychotherapy. The secondary objectives were to study predictive factors of the outcome in parents (anxiety/depression symptoms) and parent-child relationship. METHOD: In order to highlight medium-effect size, 255 toddlers (age: 18 to 48 months) needed to be included. Outcomes will be assessed by comparing the pre- and post-therapy scores of a battery of questionnaires that assess the child's symptoms, the parents' anxiety/depression, and the parent-child relationship. Multivariate linear regression analysis will be used to identify predictive factors of the outcome among the studied variables (child age and sex, socio-economic status, life events, disorder type, intensity and duration, social support, parents' psychopathology, parents' attachment, parent-child relationships, therapy length and frequency, father's involvement in the therapy, and therapeutic alliance). EXPECTED RESULTS AND CONCLUSION: This study should allow identifying some of the factors that contribute to the outcome of externalizing and internalizing disorders, and distinguishing between pre-existing and treatment-related variables. It should also help to identify children at higher risk of poor outcome who require special vigilance on the part of the therapist. It should confirm the importance of therapeutic alliance.

[Cognitive profiles in pervasive developmental disorders]. / Les profils cognitifs dans les troubles envahissants du développement.

OBJECTIVE: This study investigated the cognitive skills in pervasive developmental disorders (PDD). METHODOLOGY: Two groups of children participated in this study, 39 individuals with autism and 18 individuals with Asperger syndrome. Each participant was assessed by the Wechsler scales: WPPSI-III, WISC-III or WISC-IV. RESULTS: Children with Asperger syndrome have VIQ more than PIQ and the children with autism have VIQ less than PIQ. The performances in "block design" task vary according to the cognitive level and not according to the PDD type. The high-functioning autistic children show high performance in "block design" task. Children with Asperger syndrome revealed impairments in the "understanding of social situations" task. DISCUSSION: Individuals with autism have a verbal intelligence quotient lower than individuals with an Asperger syndrome. Several hypotheses have tried to explain verbal differences between children with autism and Asperger syndrome. A first hypothesis proposed a developmental convergence between these two groups. A second hypothesis suggested that communication and social interaction impairments could be implicated in verbal skills. A third hypothesis supported that individuals with Asperger syndrome could develop a specific cognitive style. Children with autism have spatial and perceptive capacities better than verbal capacities. These performances could be interpreted as the expression of a specific cognitive style based on the visual analysis of the detail. CONCLUSION: The low-functioning children with autism have a cognitive profile with PIQ more than VIQ and high skills in spatial organization. The high-level children with autism have a cognitive profile with PIQ more than VIQ and high skills in spatial abstraction. Children with Asperger syndrome have a profile VIQ more than PIQ profile, they are particularly good in verbal learning notably vocabulary.

[Schizophrenia and cognition: a neurodevelopmental approach]. / Schizophrénie et cognition: perspective neurodéveloppementale.

Accumulating evidence supports the hypothesis of abnormal neurodevelopment in schizophrenia. According to this hypothesis, schizophrenia is the consequence of prenatal abnormalities resulting from the interaction of genetic and environmental factors. In line with this hypothesis, several studies indicate that pregnancy and birth complications are risk factors for developing schizophrenia. At the clinical level, multiple cognitive deficits can be found in schizophrenic patients before illness onset. The neurodevelopmental hypothesis considers these cognitive deficits as the expression of early abnormalities on the central nervous system development. Consistently, brain imaging data show early structural abnormalities and abnormal progressive brain changes in schizophrenia. Finally, genetic and histological data indicate that genes associated with schizophrenia are involved in brain development.

Evolution and characteristics of the use of valproate in women of childbearing age with bipolar disorder: Results from the FACE-BD cohort.

BACKGROUND: Valproate is associated with teratogenic and neurodevelopmental effects. Several agencies have restricted the conditions of its prescription in bipolar disorders (BD). We aimed to assess the evolution of valproate prescription and the clinical profile of BD women of childbearing age receiving valproate. METHODS: Based on a large national cohort, we included all BD women 16-50 years old. Sociodemographic, clinical and pharmacological data were recorded. Logistic regression analyses were used to describe variables associated with valproate prescription. RESULTS: Of the 1018 included women 16-50 years old, 26.9% were treated with valproate with a mean daily dosage of 968 mg. The prevalence of BD women using valproate was 32.6% before May 2015 and 17.3% after May 2015 (p<0.001), the date of French regulatory publication of restriction of valproate prescription. The multivariate analysis revealed that the inclusion period after May 2015 (OR=0.54, CI 95% 0.37-0.78, p=0.001), the age lower than 40 years (OR=0.65, CI 95% 0.43-0.98, p=0.040) and the number of lifetime mood episodes (OR=0.98, CI 95% 0.95-0.99, p=0.040) were the variables negatively associated with the use of valproate. LIMITATIONS: Study could be underpowered to determine a clinical profile associated with valproate prescription. CONCLUSIONS: The regulatory change in BD women of childbearing age had a significant impact on valproate prescription, even if the prescription rate remains high. Important efforts are needed to help clinicians and patients to improve quality of care in BD women of childbearing age.

Implicit theories of intelligence and IQ test performance in adolescents with Generalized Anxiety Disorder.

During the past decade, several studies have reported positive effects of cognitive-behavioral therapy (CBT) in the treatment of children and adolescents with mental disorders. One of the most important CBT interventions is to teach children and adolescents to challenge negative thoughts that lead to maladjusted behaviors. Based on the implicit theories of intelligence framework, the main purpose of this study was to test whether an incremental theory manipulation could be used to affect IQ test performance in adolescents with Generalized Anxiety Disorder (GAD). Results showed that patients demonstrated enhanced IQ performance and experienced less state anxiety when they were exposed to an incremental theory of intelligence manipulation. Our findings suggest that incremental theory manipulation provides a useful cognitive strategy for addressing school-related anxiety in adolescents with mental disorders such as GAD.

Folie à deux and homicide: Literature review and study of a complex clinical case.

Folie à deux is a psychiatric illness involved in homicides. OBJECTIVE: To study the mechanisms leading to homicide and determine homicide risk factors in folie à deux patients through a literature review and the study of a complex clinical case. MATERIALS AND METHODS: We included articles available on PubMed, ScienceDirect or Cairn that address the forensic implications of folie à deux. Then, we analyzed the criminal psychiatric assessments of two murderers (husband and wife) of a child in a case of folie à deux. RESULTS: Seventeen articles were included. In the cases examined, homicides were committed with great violence, usually against a victim in the family circle, and were sometimes followed by suicide. The main risk factor for homicide was the combination of mystical and persecutory delusions. The homicides occurred in response to destabilization of the delusional dyads. Concerning the clinical case, we described the circumstances surrounding the killing and analyzed the four expert reports that permit us to infer the occurrence of induced psychosis, which is a form of folie à deux. DISCUSSION: Psychiatrists must attain a better knowledge of folie à deux to allow early identification of risk situations and to improve their assessments.

[Sensory modulation disorders and impairments in adaptative skills in autism spectrum disorders]. / Troubles de la modulation sensorielle et difficultés adaptatives dans les troubles du spectre de l'autisme.

INTRODUCTION: People suffering from autism spectrum disorders (ASD) provide atypical responses to sensorial stimulations, indicating specific sensory processing. These responses vary from one another and within the same individual with ASD, resulting in maladaptive functional capacities in everyday life. Factors explaining those specificities are poorly defined and need to be better identified. OBJECTIVES: To examine the relationship between sensory modulation symptoms (SMSs) and maladaptive behaviors in a group of children with ASD. To study how the sensory processing patterns in ASD are related to chronological age, intensity of autistic symptoms, and associated intellectual disability. METHOD: A transversal observational study of a group of children with ASD was conducted for 1 year in an Autism Resource Centre in Marseille, France. The SMSs were assessed using the Dunn short sensory profile. The adaptive behaviors and social quotient were assessed using the Vineland adaptive behavior scale. RESULTS: Forty-five children with ASD completed both scales. Significant correlations were found between SMS intensity and the children's adaptive behaviors. Furthermore, chronological age and intellectual disability showed a significant relationship with SMS intensity; chronological age and intellectual disability were also found to be significantly related. However, the severity of autistic symptoms was not associated with the intensity of SMSs. CONCLUSION: These outcomes give a better understanding of sensory processing in ASD. The analysis of sensory processing is valuable during the diagnostic phase and for the development of individualized/custom-tailored interventions.

[Predictive factors of depression in adolescents at school: the role of implicit theories of intelligence]. / Facteurs prédicteurs de la dépression chez l'adolescent en contexte scolaire: rôle des théories implicites de l'intelligence.

INTRODUCTION: The aim of this study was to complete the identification of predictive factors of depression during adolescence. For some authors, depression is characterized by a style of attribution, which consists essentially in attributing most of the negative outcomes to internal, stable, and uncontrollable factors. It seems that these attributions depend essentially on the type of their beliefs and in particular, those concerning the nature of intelligence. These beliefs called "implicit theories of intelligence", are the entity theory of intelligence and the incremental theory of intelligence. The entity theory of intelligence corresponds to the belief according to which intelligence is the expression of a relatively stable, fixed, and noncontrollable feature, and which we cannot change. In contrast, the incremental theory corresponds to the belief according to which intelligence is a controllable quality, which we can develop through effort and work. Several studies have demonstrated that the adolescents who consider intelligence as a malleable quality explain their bad results by internal, unstable, and controllable factors. Conversely, students who consider intelligence as a fixed capacity tend to strongly attribute their failure to internal, stable, and uncontrollable factors. We have consequently formulated the hypothesis according to which the entity theory should be a predictive factor of depression. We have also tested the fact that anxiety should be a mediating factor within the relation between the entity theory and depression. METHOD: The sample was composed of 424 adolescents. Using different questionnaires, we measured implicit theories of the intelligence (TIDI), self-esteem (EES), anxiety (STAI-Form Y-B) and depression (CDI). RESULTS: Multiple regression analyses demonstrated that the entity theory of intelligence positively predicts depression. Self-esteem negatively predicts anxiety and depression. Moreover, anxiety is a mediator of the relation between self-esteem and depression, on one hand, and the relation between the entity theory of intelligence and depression, on the other. Finally, the effect of the entity theory of intelligence appears to be modulated by the level of self-esteem. DISCUSSION: This study explains the mechanisms by which the implicit theories of intelligence engender anxiety and depression. Furthermore, this approach provides interesting perspectives in the prevention and management of adolescents presenting depression.

[Validation study of the implicit theories of intelligence scale]. / Validité factorielle d'un questionnaire mesurant les théories implicites de l'intelligence (TIDI).

BACKGROUND: According to several authors, it seems that beliefs about the nature of intelligence have a very powerful impact on behavior in learning situations. These implicit theories of intelligence create a meaning system or conceptual framework that influences the individuals interpretation of school situations. Thus, an entity theory of intelligence is the belief that intelligence is a fixed trait, a personal quality that cannot be changed. Students who subscribe to this theory believe that although people can learn new things, their underlying intelligence remains the same. In contrast, an incremental theory of intelligence is the belief that intelligence is a malleable quality that can increase through efforts. This paper presents the development and the validation of the Implicit Theories Of Intelligence scale (TIDI) for French teenagers. Most of the studies attest the validity of the scales measuring the implicit theories of the intelligence. The instrument used by the authors include 3 items assessing the entity theory. Recently, theoretical debates suggested to measure within a single questionnaire both theories at the same time. Moreover, there is no instrument in French language which measures the implicit theories of the intelligence. Two studies have been conducted. The purpose of the first study was to test the factorial validity and the internal consistency of the scale. The goal of the second study was to test the temporal stability of the instrument. STUDY 1: This study describes the procedures used to create the TIDI, the internal consistency and the factorial validity. This instrument was composed of two subscales of three items assessing incremental theory of the intelligence and entity theory of the intelligence. French teenagers (n=453) aged 11 to 16 years completed the questionnaire during a lecture. Cronbach's alpha was 0.81 for the scale assessing incremental theory and 0.78 for the scale assessing entity theory. Confirmatory factor analysis was conducted using Lisrel. The fit for this model was: chi2 (8)=24.23, p<0.01, GFI=0.98, CFI=0.98, RMSEA=0.067, AGFI=0.95. All indexes of fit improved. An examination of the output indicated that the range of factor loadings of items on their respective scales was 0.66 to 0.82. These statistical analyses reveal that the TIDI shows an excellent internal consistency and a very good validity. STUDY 2: This second study examines the temporal stability of the TIDI. The sample includes 209 French teenagers aged 11 to 16 years who completed the questionnaire and participated at the second administration of the questionnaire, three months later. The stability coefficient for entity theory was 0.74 and for incremental theory was 0.70. These results indicate that the TIDI is stable over time, thus supporting its temporal stability. CONCLUSION: The overall results presented in these studies confirm the excellent psychometric properties of the TIDI. These studies also attest that a teenager can subscribe in a simultaneous way to both implicit theories of intelligence. Although a theory is dominant, the opposite theory can be available according to the context. From a theoretical point of view, this questionnaire could be used within correlational studies in order to study the correlation between the implicit theories and the psychopathological variables such as anxiety and depression. From a pragmatic point of view, this questionnaire can be used for the treatment of children with learning disabilities.

[Autism and mental retardation: a study of the early social communication]. / Autisme et retard mental: étude de la communication sociale précoce.

OBJECTIVE: To determine developmental communication profiles in young autistic children with mental retardation. METHODS: A group of 19 autistic children (mean age=43 months) were matched with a group of 11 mentally retarded children (mean age=39 months) on mental age (17,6 months). All of these children were without speech (less than 5 words of vocabulary). Communication skills were assessed with the Guidetti-Tourrette scales (ECSP), French adaptation of the Seibert-Hogan scales. RESULTS: Autistic children displayed a much lower score than mentally retarded children in the 3 functions of early social communication (behavior regulation, social interaction and joint attention). The developmental communication profiles was the same in the 2 groups. DISCUSSION: The results showed evidence of distortion in autistic children development: they displayed important deficits in communication skills, in comparison with cognitive skills. Autistic children mainly displayed requesting gestures: they used adults to help them to reach a goal, instead of regarding them as social partners. However, young children who have mental age less than 18 months mainly use the same functions of communication, with or without autistic trouble. CONCLUSIONS: There is a same developmental sequence in communication skills in young children, with or without autistic trouble.

Is the French criminal psychiatric assessment in crisis?

The criminal psychiatric assessment in France seems to be facing growing criticism related to disagreements between experts and, on the other hand, a lack of interest of psychiatrists for the assessment. We start by explaining the current framework of the criminal psychiatric assessment in France, which differs from the assessment used in English-speaking countries, where Roman law applies. Then, we will describe the disagreements through a literature review and two clinical vignettes. Finally, we will try to understand the causes of discrepancies between experts and the reasons for a supposed lack of interest of the psychiatrists for the expertise. For this, we conducted a survey among the psychiatric experts. We individually questioned experts on the discrepancies and on their awareness of the expertise. We found that 75% of the experts we surveyed had already faced the divergent opinion of a colleague. In addition, the experts were divided on their conclusions related to the fictional scenario we gave them for an a priori assessment (a person with schizophrenia who was accused of murder), particularly in the specific contexts that we submitted to them. The main cause of disagreement between experts was the various schools of thought that influence the psychiatric experts in the forensic discussion and, therefore, the conclusions of a case. Moreover, the experts believed that the decrease in the number of psychiatric experts could be attributed to the adverse financial situation of the assessment, the considerable workload required, and the extensive responsibility that falls on the expert. Calling on a team of forensic experts to perform assessments seems to be the first solution to this crisis. Furthermore, if the experts were better compensated for the assessments, more people would want to undertake this work.

[Infantile anorexia: from birth to childhood]. / Les anorexies infantiles: de la naissance à la première enfance.

Young child's anorexia (0-4 years) may have organic or psychological origin, when parents-child relationships are concerned. The most complex and earliest forms often have unspecified aetiology. Psychopathological classifications, which emphasize the mother-child relationships, are essential reference marks. But there is now a consensus in the definitions: the diagnosis of infantile anorexia requires criteria of acute or chronic malnutrition. We mainly distinguish anorexia by early disorder of homeostasis, anorexia resulting from serious disorder of attachment, anorexia by disorder of mother-child interactions, and finally early and complex anorexia, mixing an organic vulnerability and a bonding trouble, which can be secondary. Treatments differ according to the selected aetiology. Even if the origin is not mainly the fact of a relational mother-child dysfunction, parents-child's relations require a support to avoid aggravation by interactive vicious circles (force feeding). More than other diseases of early childhood, feeding disorders require a good knowledge of the working hypotheses both in the field of the paediatrics and the child psychiatry.

[Isolated auditory hallucination in prepubertal children: Diagnostic framework and predictive value]. / L'hallucination auditive isolée chez l'enfant pré-pubère : cadre diagnostique et valeur prédictive.

Isolated auditory hallucination is a common symptom, probably underdiagnosed, in prepubertal children. There is currently no consensus to guide the care for such manifestations; however, they are often painful for the patients. The literature emphasizes the unspecific and transnosographic aspect of this symptom. The most common symptom is having one's name called by voices, which often remains without predictive value, associated with anxiety disorders. However, isolated auditory hallucination is a useful clinical source to detect an underlying psychiatric disorder, especially when symptoms are complex, severe, or persistent. Although medical follow-up is always necessary, psychological follow-up can sometimes be beneficial, but medication should not be used before a 6-month observation and limited to cases that reveal an underlying pathology.

[Food preferences in anorectic girls at the beginning of therapy]. / Etude des préférences alimentaires chez la jeune fille anorexique au début de la prise en charge thérapeutique.

To determine the eating habits of patients with anorexia nervosa, we compared a group of 21 anorectic girls satisfying DSM-III-R criteria (A: 19 +/- 6.6 years; 14.2 +/- 2 kg/m2) with 30 control girls (C: 19.8 +/- 3.3 years; 20.9 +/- 4.4 kg/m2). A standardised form listing 226 food items was used to assess their food preferences. For each food category except vegetables and fish, the medium rate of positive appreciation was lower in group A than in group C. However, a positive correlation was found between the two groups (except for dairy and diet products), showing no major distortion of taste in group A. Anorectic girls generally discarded the sweetest fruit and the fattest meats, but sometimes chose to eat high-calorie food, possibly because of its supposed nutritional value. Their dislike for so-called "light" products was also apparent. Moreover, no regressive tendency to childish choices was found in their eating habits. It is concluded that group A displayed a narrowed food field, but without distortions of taste.

Major symptoms and differential diagnosis of neuroleptic malignant syndrome: three case reports.

The authors describe the cases of three patients presenting a major extrapyramidal symptom with rising CPK, inconstant hyperthermia and autonomic dysfunction. Through a brief review of the literature, the authors question the unity of the malignant syndrome. If hypertonia is quite constant, the rise in the seric CPK is aspecific and hyperthermia is inconstant.

[Gifted children and dysharmonious development]. / Enfant surdoué et dysharmonie de développement.

Gifted children are exposed to psychological disturbances. How much this psychological fragility is of a constitutional origin or is acquired, resulted from their intellectual precocity, is unclear. Nevertheless it justifies an early recognition of these children, knowing that psychological disturbances may be present early in life and mask the intellectual precocity. This is illustrated by the case of a three-year-old girl. Psychometric tests should be performed on an individual basis in order to avoid the negative effects of affective and emotional factors; an IQ above 140 characterizes gifted children. However, creativity tests are equally important allowing to identify their high capacity of originality and creativity. Uneven development of intelligence, affectivity and psychomotricity is frequent, which may induce anxiety disorders, obsessional behaviour and personality disorders. It appears that the higher the IQ is, the greater the psychological fragility, this fragility usually being important for an IQ above 170. The education of gifted children should be concentrated on the development of creativity and reflection, avoiding the tediousness of learning mainly based on memorizing and the acquisition of mechanisms. Early intervention is recommended in the case of psychological and behavioural disturbances, as an attempt to prevent the risk of pathological psychological organization.

[Statistical study of mental disorders in New Caledonia]. / Etude statistique des maladies mentales en Nouvelle-Calédonie.

315 patients admitted to the psychiatric hospital of Nouville, New-Caledonia, during the year 1987, are examined. There are several ethnies: Melanesians, Europeans, Wallisians. Europeans are admitted for depression, suicide and neurotic troubles. On the contrary Melanesians and Wallisians are admitted for acute and chronic psychotic troubles above all. Maniac-depressive illness exists in every ethny. There are a lot of psychopathological hypothesis. Indigenous medicine of Melanesians in New-Caledonia has a great part in the distribution of diagnostics.

Atypical sulcal anatomy in young children with autism spectrum disorder.

Autism spectrum disorder is associated with an altered early brain development. However, the specific cortical structure abnormalities underlying this disorder remain largely unknown. Nonetheless, atypical cortical folding provides lingering evidence of early disruptions in neurodevelopmental processes and identifying changes in the geometry of cortical sulci is of primary interest for characterizing these structural abnormalities in autism and their evolution over the first stages of brain development. Here, we applied state-of-the-art sulcus-based morphometry methods to a large highly-selective cohort of 73 young male children of age spanning from 18 to 108 months. Moreover, such large cohort was selected through extensive behavioral assessments and stringent inclusion criteria for the group of 59 children with autism. After manual labeling of 59 different sulci in each hemisphere, we computed multiple shape descriptors for each single sulcus element, hereby separating the folding measurement into distinct factors such as the length and depth of the sulcus. We demonstrated that the central, intraparietal and frontal medial sulci showed a significant and consistent pattern of abnormalities across our different geometrical indices. We also found that autistic and control children exhibited strikingly different relationships between age and structural changes in brain morphology. Lastly, the different measures of sulcus shapes were correlated with the CARS and ADOS scores that are specific to the autistic pathology and indices of symptom severity. Inherently, these structural abnormalities are confined to regions that are functionally relevant with respect to cognitive disorders in ASD. In contrast to those previously reported in adults, it is very unlikely that these abnormalities originate from general compensatory mechanisms unrelated to the primary pathology. Rather, they most probably reflect an early disruption on developmental trajectory that could be part of the primary pathology.

[Prospective assessment of children with pervasive developmental disorder after 2 years of day-hospital treatment]. / Évaluation prospective d'enfants atteints d'un trouble envahissant du développement après deux ans de prise en charge en hôpital de jour.

The treatment of children with pervasive developmental disorders (PDD) has not been systematically assessed in French day-care units. In this prospective study, 11 children with a diagnosis of PDD were followed up for 2years in a day-care unit in the Marseille university hospital. The treatment they received is based on an initial assessment by the "Centre Ressources Autisme" (CRA PACA) and further included a continued observation of the child and an assessment of the child's abilities and needs. This treatment used various therapeutic approaches 10h weekly and also included parental counseling and coordinated work with schools. Treatment in our day-care unit can be categorized as eclectic, non-intensive therapy. It is based on methods such as TEACCH (Treatment and Education of Autistic and related Communication handicapped Children), Floor Time Play, speech and language therapy, developmental therapy, and psychotherapy. International studies on intensive behavioral therapies suggest that this treatment is superior to non-behavioral and/or non-intensive treatment. They suggest its efficiency is due both to the nature of the treatment (behavioral) and to its intensity (more than 25h a week). In this study, the CRA diagnosed children using the ADI and ADOS. The 11 children (mean age, 3years 5months) were tested twice, with the Vineland and CARS scales. The first assessment was on admission to the day hospital and the second was 2years later. The results showed developmental progress with a mean increase of 13.5 months at the Vineland Scale, and a decrease of the autism severity score on the CARS. The treatment presented here proves to be efficient; if compared to similar results in international studies, we obtained better results than their eclectic intensive or non-intensive treatment comparison group.
