Note. ASD = autism spectrum disorder. CPS = couple problem-solving.

Mothers’ and fathers’ ratings of number of positive marital interactions and negative marital interactions were estimated simultaneously in one multivariate HLM. In Level 1, number of positive marital interactions and number of negative marital interactions were person-centered. The average daily number of positive marital interaction and number of negative marital interactions were included at Level 2.
