文献概要

We investigated the association between everyday memory and autistic traits in adults with autism spectrum disorder (ASD, n＝22) and healthy adults (n＝20) by using the Rivermead Behavioral Memory Test (RBMT). A generalized linear model (GLM) was used to explore the relationships between the subjects' performance on the RBMT as the objective variable and the composite score of the Autism Spectrum Quotient (AQ) as the explanatory variable. Multiple models were created with the AQ subscales (‘Social skills,’ ‘Attention-shifting,’ ‘Attention to details,’ ‘Communication,’ ‘Imagination’), age, gender, the full-scale intelligence quotient (FSIQ), the Patient Health Questionnaire-9 (PHQ-9), and the General Anxiety Disorder-7 (GAD-7) scale added as the moderator variables. The GLM revealed that the AQ subscale ‘Social skills’ significantly predicted the RBMT-total scores with age, gender, and psychological measures scores as the moderator variables (Model 4: B＝0.752, 95%CI: 0.191 to 1.313, p＜0.01). Also, The GLM revealed that the AQ subscale ‘Communication’, in addition to ‘Social skills’, significantly predicted the RBMT- ‘Prospective memory’ (Model 4: B＝0.298, 95%CI: 0.19 to 0.578, p＜0.05). These results indicate an influence of social skills on everyday memory functioning, highlighting the weakness of memory processing in everyday life situations among individuals with ASD.
