Assessing Autism in Adults: An Evaluation of the Developmental, Dimensional and Diagnostic Interview-Adult Version (3Di-Adult) / W. MANDY in Journal of Autism and Developmental Disorders, 48-2 (February 2018)

Titre : Assessing Autism in Adults: An Evaluation of the Developmental, Dimensional and Diagnostic Interview-Adult Version (3Di-Adult) Type de document : Texte imprimé et/ou numérique Auteurs : W.

SKUSE, Auteur Article en page(s) : p.549-560 Langues : Anglais (eng) Mots-clés : Adults Assessment and diagnosis Autism spectrum conditions (ASC) Autism spectrum disorder (ASD) Diagnostic and statistical manual, fifth edition (DSM-5) Index. décimale : PER Périodiques Résumé : We developed a brief, informant-report interview for assessing autism spectrum conditions (ASC) in adults, called the Developmental, Dimensional and Diagnostic Interview-Adult Version (3Di-Adult); and completed a preliminary evaluation. Informant reports were collected for participants with ASC (n = 39), a non-clinical comparison group (n = 29) and a clinical comparison group (n = 20) who had non-autistic mental health conditions. Mean administration time was 38 min (50 min for ASC). Internal consistency (alphas >/= 0.93) and inter-rater agreement (ICCs >/= 0.99) were high. When discriminating ASC from non-ASC, the 3Di-Adult showed excellent sensitivity (95%) and specificity (92%). The 3Di-Adult shows promise as a psychometrically sound and time-efficient interview for collecting standardised informant reports for DSM-5 assessments of ASC in adults, in research and clinical practice.

Titre : Assessing general cognitive and adaptive abilities in adults with Down syndrome: a systematic review Type de document : Texte imprimé et/ou numérique Auteurs : S. HAMBURG, Auteur ; B. LOWE, Auteur ; C. M. STARTIN, Auteur ; C. PADILLA, Auteur ; A. COPPUS, Auteur ; W. SILVERMAN, Auteur ; J. FORTEA, Auteur ; S. ZAMAN, Auteur ; E. HEAD, Auteur ; B. L. HANDEN, Auteur ; I.

Langues : Anglais (eng) Mots-clés : Ab Adaptive ability Adaptive behaviour Cognition Down syndrome General ability Iq Intelligence Index. décimale : PER Périodiques Résumé : BACKGROUND: Measures of general cognitive and adaptive ability in adults with Down syndrome (DS) used by previous studies vary substantially. This review summarises the different ability measures used previously, focusing on tests of intelligence quotient (IQ) and adaptive behaviour (AB), and where possible examines floor effects and differences between DS subpopulations. We aimed to use information regarding existing measures to provide recommendations for individual researchers and the DS research community. RESULTS: Nineteen studies reporting IQ test data met inclusion for this review, with 17 different IQ tests used. Twelve of these IQ tests were used in only one study while five were used in two different studies. Eleven studies reporting AB test data met inclusion for this review, with seven different AB tests used. The only AB scales to be used by more than one study were the Vineland Adaptive Behaviour Scale (VABS; used by three studies) and the Vineland Adaptive Behavior Scale 2nd Edition (VABS-II; used by two studies). A variety of additional factors were identified which make comparison of test scores between studies problematic, including different score types provided between studies (e.g. raw scores compared to age-equivalent scores) and different participant inclusion criteria (e.g. whether individuals with cognitive decline were excluded). Floor effects were common for IQ tests (particularly for standardised test scores). Data exists to suggest that floor effects may be minimised by the use of raw test scores rather than standardised test scores. Raw scores may, therefore, be particularly useful in longitudinal studies to track change in cognitive ability over time. CONCLUSIONS: Studies assessing general ability in adults with DS are likely to benefit from the use of both IQ and AB scales. The DS research community may benefit from the development of reporting standards for IQ and AB data, and from the sharing of raw study data enabling further in-depth investigation of issues highlighted by this review.
