The emotional burden subscale produced the strongest model overall, with demographics, illness perception clusters, and relationship quality explaining 51.1% of variance in emotional burden. Covariates accounted for 41% of the variance in regimen-related distress, 20% of the variance in interpersonal distress, and 8.6% of the variance in physician-related distress.Cluster membership was strongly associated with emotional burden, regimen-related distress, and to a lesser degree interpersonal distress, but was not associated with physician-related distress. Relationship quality significantly predicted all four subcategories of diabetes distress, however most strongly predicted regimen-related distress. Illness perception schemas and interpersonal issues have important influences on emotional adjustment in Type 2 diabetes. This study provides direction for the content of a novel, multifaceted approach to identifying and reducing diabetes distress in people with Type 2 diabetes.
