Drawing from role theory, stress and coping, and caregiving literatures, this paper develops a model of family-role overload involving two forms of caregiver burden (subjective, objective) and two types of maladaptive changes in employee behavior (at work, personal), and hypothesizes that caregiver type (eldercare-only vs. sandwich) moderates all paths in the model. Partial Least Squares structural equation modeling (SEM) supported all hypothesized direct paths.
