Severity of Child Autistic Symptoms and Parenting Stress in Mothers of Children with Autism Spectrum Disorder in Japan and USA: Cross-Cultural Differences

Figure 6

(a). Difference between the U.S. and Japan with respect to the quadratic association between the parenting stress index (PSI) total score and the social responsiveness scale-2 (SRS-2) total t-score centered at sample mean. Note: (a) is a graphical display of the following fitted quadratic regression model: “mean (maternal stress level based on parenting stress index total score)” = “87.52 + 0.97 × (SRS-2 t-score − 79.5) − 0.05 × (SRS-2 t-score  − 79.5)²–1.94 × (Country) − 0.15 × [(SRS-2 t-score − 79.5) × Country] + 0.02 × [(SRS-2 t-score − 79.5)² × Country]”. value for interaction between the country of residence and SRS-2 total t-score centered at sample mean = 0.70. (b). Difference between the U.S. and Japan with respect to the quadratic association between the child domain score of the parenting stress index (PSI) and the social responsiveness scale-2 (SRS-2) total t-score centered at sample mean. Note: (b) is a graphical display of the following fitted quadratic regression model: “mean (maternal stress level based on parenting stress index child domain score)” = “97.80 + 0.44 × (SRS-2 t-score − 79.5) − 0.06 × (SRS-2 t-score − 79.5)²–2.83 × (Country) + 0.47 × [(SRS-2 t-score − 79.5) × Country] + 0.01 × [(SRS-2 t-score − 79.5)² × Country]” value for the interaction between the country of residence and SRS-2 total t-score centered at sample mean = 0.33. (c). Difference between the U.S. and Japan with respect to the quadratic association between the parent domain score of the parenting stress index (PSI) and the social responsiveness scale-2 (SRS-2) total t-score centered at sample mean. Note: (c) is a graphical display of the following fitted quadratic regression model: “mean (maternal stress level based on parenting stress index parent domain score)” = “67.22 + 1.50 × (SRS-2 t-score − 79.5) − 0.01 × (SRS-2 t-score − 79.5)² + 2.23 × (Country) − 1.12 × [(SRS-2 t-score − 79.5) × Country] + 0.004 × [(SRS-2 t-score − 79.5)² × Country]” value for the interaction between the country and SRS-2 total t-score centered at sample mean = 0.18.
