Note: Values represent commonality coefficients. Commonality coefficients are similar to beta; however they specifically represent the isolated, unique and common variance each individual variable (and combination of variables) contributes to the dependent variable. P=Parent-report, C= child self-report, MASC-2=Multidimensional Anxiety Scale for Children - Second Edition, OCD=Obsessive Compulsive Disorder, RRBs=Restricted and Repetitive Behaviors, SRS-2 =Social Responsiveness Scale – Second Edition, ASD=Autism Spectrum Disorder, SCI = Social Communication and Interaction, ADOS-2=Autism Diagnostic Observation Scale – Second Edition.
