The aim of the present study was to examine the predictive value of social support and coping for individual and marital adaptation in adult men with autism spectrum disorder (ASD) and their spouses, based on the double ABCX model of adaptation. Twenty-one couples participated in the study and completed measures of stressor severity, social support, coping, individual and marital adaptation. Bivariate analyses showed that each of the model components was related to adaptation in men and women. Hierarchical regression analyses revealed that, after controlling for relevant demographics and stressor severity, informal support was a strong, and unique predictor of adaptation in both spouses (explained variance: 27–89%). Coping did not add to the prediction of adaptation. Clinical implications and limitations are discussed.
