Purpose: The study investigates the predictors of caregivers' experienced burden, stigma, and well-being, when looking after family members diagnosed with a psychiatric disorder.Design and Methods: This cross-sectional study included 168 caregivers; perceived burden, stigma, well-being, knowledge, illness perception, and medical variables were assessed.Findings: A number of correlates of burden, stigma, and well-being have been identified and are being discussed. The integrative predictive model showed that the caregiver's emotional representation of illness best predicts burden (β = 0.38, p < 0.001), stigma (β = 0.53, p < 0.001) and well-being (β = −0.36, p < 0.001).
