Since a confirmatory factor analysis revealed no factor validity of the CAT-Q-J for both autistic and non-autistic adults, an exploratory factor analysis was conducted to ensure the psychometric properties matched those of the original scale as much as possible. The results showed the CAT-Q-J comprised three subscales, a four-item compensation subscale, a five-item masking scale, and a five-item assimilation subscale. The overall CAT-Q-J and all three subscales showed sufficient internal consistency and moderate-to-good and stable test-retest reliability in both the autistic and non-autistic samples. Convergent validity was also supported by the correlations found with measures of autistic traits, well-being, anxiety, and depression. Different from the original CAT-Q, compensation/masking for the autistic sample was not correlated with mental health or autistic traits. The reliability and the validity of the overall CAT-Q-J were confirmed; however, caution should be exercised when interpreting its subscales.

The association between social camouflage and mental health among autistic people in Japan and the UK: a cross-cultural study / Fumiyo OSHIMA in Molecular Autism, 15 (2024)  

Public ISBD [article]  inMolecular Autism > 15 (2024) . - 1p. Titre : The association between social camouflage and mental health among autistic people in Japan and the UK: a cross-cultural study Type de document : Texte imprimé et/ou numérique Auteurs : Fumiyo OSHIMA, Auteur ; Toru TAKAHASHI, Auteur ; Masaki TAMURA, Auteur ; Siqing GUAN, Auteur ; Mikuko SETO, Auteur ; Laura HULL, Auteur ; William MANDY, Auteur ; Kenji TSUCHIYA, Auteur ; Eiji SHIMIZU, Auteur Article en page(s) : 1p. Langues : Anglais (eng) Mots-clés : Male  Adult  Humans  Female  Autistic Disorder/diagnosis  Japan/epidemiology  Mental Health  Cross-Cultural Comparison  Cross-Sectional Studies  United Kingdom/epidemiology  Autistic adults  Cross-cultural study  Japan  Social camouflage  Uk Index. décimale : PER Périodiques Résumé : BACKGROUND: To examine the relationship between social camouflage and mental health in Japanese autistic adults and make an international comparison with a sample from the UK. METHODS: This study analysed secondary data of participants with a self-reported diagnosis of autism from Japan (N = 210; 123 men and 87 women) and the UK (N = 305; 181 women, 104, men, and 18 nonbinary). The relationships between the quadratic term of the Camouflaging Autistic Traits Questionnaire and mental health scales, including depression and anxiety, were assessed. RESULTS: The UK sample showed linear relationships, whereas the Japanese sample showed significant nonlinear relationships. The quadratic terms of the Camouflaging Autistic Traits Questionnaire slightly explained generalised anxiety (? = .168, p = .007), depression (? = .121, p = .045), and well-being (? = -?.127, p = .028). However, they did not explain the association between social anxiety and the Camouflaging Autistic Traits Questionnaire. LIMITATIONS: Participants had self-reported diagnoses, and while the autism-spectrum quotient provides a cut-off value for screening, it does not enable confirming diagnoses. Mean scores of the Japanese version of the Camouflaging Autistic Traits Questionnaire were lower as compared to the original CAT-Q, which implies that the social camouflage strategy types used by autistic people in Japan and the UK could differ. The cross-sectional design limits causal inferences. CONCLUSION: In the UK, more social camouflage was associated with poorer mental health scores, whereas too little or too much social camouflage was associated with a low mental health score in Japan. The Japanese population is seemingly less aware of and educated on autistic characteristics and considers 'average' behaviour a good thing. This could influence Japanese autistic people's social camouflage use, differing from that of autistic people in the UK. The differences in the relationship between social camouflage and mental health between Japan and the UK could be associated with national-level divergence regarding the culture of autism.

The Lack of Alterations in Metabolites in the Medial Prefrontal Cortex and Amygdala, but Their Associations with Autistic Traits, Empathy, and Personality Traits in Adults with Autism Spectrum Disorder: A Preliminary Study / Kazuki MATSUMOTO ; Fumio OSONE ; Akira HARA ; Siqing GUAN ; Sayo HAMATANI ; Katsumasa MUNEOKA ; Koichi SATO ; Akihiro OKADA ; Tokuzou YOKOKAWA in Journal of Autism and Developmental Disorders, 54-1 (January 2024)

We investigated brain metabolites in the medial prefrontal cortex and amygdala of 24 drug-naive adults with ASD and no intellectual disability and 24 non-ASD control subjects, using 3 T 1H-MRS. Adults with ASD showed no significant differences from control in glutamate, glutamate plus glutamine, N-acetylaspartate, glycerophosphorylcholine plus phosphorylcholine, creatine plus phosphocreatine, or myo-inositol in either region. However, ASD subjects did show significant correlations of localized brain metabolites with autistic traits, empathy deficits, and personality traits using the Autism-Spectrum Quotient, Questionnaire of Cognitive and Affective Empathy, Interpersonal Reactivity Index, and NEO Personality Inventory-Revised. These findings should be taken as preliminary or exploratory.
