Brief Report: Selective Social Anhedonia in High Functioning Autism / Coralie CHEVALLIER in Journal of Autism and Developmental Disorders, 42-7 (July 2012)

MOLESWORTH, Auteur ; Sylvie BERTHOZ, Auteur ; Francesca HAPPE, Auteur Année de publication : 2012 Article en page(s) : p.1504-1509 Langues : Anglais (eng) Mots-clés : Anhedonia  Social motivation  Autism spectrum disorders  Social anhedonia  Social interest Index. décimale : PER Périodiques Résumé : Diminished social motivation is one of the most striking features in autism. Yet, few studies have directly assessed the value people with an ASD place on social interactions, or how rewarding they report it to be. In the present study, we directly measure social motivation by looking at responses to a questionnaire assessing self-reported pleasure in social and non social situations. Twenty-nine adolescents with ASD and matched controls took part in the study. Our results reveal that children with an ASD differ from the controls with respect to social enjoyment, but not with respect to physical and other sources of hedonism. Further analyses demonstrate that the degree of social anhedonia correlates with autism severity.

Matrix Reasoning and Anhedonic Depression in Male Adolescents with Autism / Christopher F. SHARPLEY in Autism - Open Access, 8-1 ([01/01/2018])  

Public ISBD [article]  inAutism - Open Access > 8-1 [01/01/2018] . - 5 p. Titre : Matrix Reasoning and Anhedonic Depression in Male Adolescents with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Christopher F. SHARPLEY, Auteur ; Vicki BITSIKA, Auteur Article en page(s) : 5 p. Langues : Anglais (eng) Mots-clés : Autism  Matrix Reasoning  Depression  Anhedonia Index. décimale : PER Périodiques Résumé : Background: Almost half of samples of young people with Autism Spectrum Disorder (ASD) experience depression but little is known about the role of overall and specific cognitive function in that depression. Investigation of this link could help explain the pathway between cognitive function and depression. Methodology: Fifty-one male adolescents with ASD, plus 18 male adolescents without ASD, completed the Wechsler Abbreviated Intelligence Scale (2nd ed.) (WASI-II) plus the Child and Adolescent Symptom Inventory-Depression (CASI-MDD) subscale. Data were analysed at the global (total IQ, depression) and subtest (IQ) and symptom (depression) levels. Results: Although there were no significant differences in overall IQ or any of the WASI-II subtests between the ASD and non-ASD samples, the ASD sample had significantly higher CASI-MDD scores. There was a significant correlation between global IQ and Matrix Reasoning with CASI-MDD total and anhedonia scores for the ASD sample, but no significant correlations between these variables for the non-ASD sample. Conclusions: Matrix Reasoning appears to be implicated in the development of anhedonic depression in adolescents with ASD.

Mimetic desire in autism spectrum disorder / Baudouin FORGEOT D'ARC in Molecular Autism, 7 (2016)  

Public ISBD [article]  inMolecular Autism > 7 (2016) . - 45p. Titre : Mimetic desire in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Baudouin FORGEOT D'ARC, Auteur ; F. VINCKIER, Auteur ; M. LEBRETON, Auteur ; I.

Autism spectrum disorder (ASD) is defined by both atypical interests and altered social interaction. We investigated whether MD is lower in adults with ASD compared to typically developed adults and whether MD correlates with social anhedonia and social judgment, two aspects of atypical social functioning in autism. Contrary to our hypotheses, MD was similarly present in both ASD and control groups. Anhedonia and social judgment differed between the ASD and control groups but did not correlate with MD. These results extend previous findings by suggesting that basic mechanisms of social influence are preserved in autism. The finding of intact MD in ASD stands against the intuitive idea that atypical interests stem from reduced social influence and indirectly favors the possibility that special interests might be selected for their intrinsic properties.

Testing a theory-driven factor structure of the autism-spectrum quotient / Yiqin ZHU in Autism Research, 15-9 (September 2022)  

Public ISBD [article]  inAutism Research > 15-9 (September 2022) . - p.1710-1718 Titre : Testing a theory-driven factor structure of the autism-spectrum quotient Type de document : Texte imprimé et/ou numérique Auteurs : Yiqin ZHU, Auteur ; Wenting MU, Auteur ; Marianne G. CHIRICA, Auteur ; Howard BERENBAUM, Auteur Article en page(s) : p.1710-1718 Langues : Anglais (eng) Mots-clés : Anhedonia  Autism Spectrum Disorder/diagnosis  Autistic Disorder  Factor Analysis, Statistical  Humans  Surveys and Questionnaires  autism  autism quotient  autism spectrum  autistic traits  factor analysis Index. décimale : PER Périodiques Résumé : The Autism-Spectrum Quotient (AQ) is a popular instrument used to assess the degree to which individuals exhibit features of autism spectrum conditions (ASC). The current study aimed to develop a theory-driven factor structure of the AQ that would fit as well across samples as the 12 previously proposed factor structures, all of which, except for the original Baron-Cohen model, had been developed on the basis of exploratory factor analysis (EFA) or principal component analysis. We first proposed a six-factor solution: (1) social anhedonia; (2) interest in details/patterns; (3) imagination ability; (4) desire for predictability/routine; (5) social cognition; and (6) social discourse convention. We tested the six-factor structure and made final item selections (27 items) with EFA using data from college students (n = 503). Then, we empirically tested alternative factor structure models in three other independent samples (ns = 503; 1263; 1641) using confirmatory factor analysis. Results indicated that our model fit as well, if not better, than all of the other models across samples, regardless of parameter estimation methods and software packages. Overall, the theory-driven replicable six-factor structure that we report holds the potential to be used to measure the six domains of features that we identified in the AQ. LAY SUMMARY: Questionnaire measures of autism spectrum conditions have typically been used to measure approximately four broad dimensions. Our study suggests that the Autism-Spectrum Quotient can be used to measure six more narrowly defined dimensions: social anhedonia, interest in details/patterns, imagination ability, desire for predictability/routine, social cognition, and social discourse convention. Additional work is needed to develop measures of a much wider variety of autism spectrum features.
