Abstract summary 

To expand current models of depressive symptoms in older adults with multimorbidity (MM) beyond the number of illnesses as a predictor of worsened mental health.Two-sample replication study of adults ≥62 years old with ≥ two chronic illnesses, who completed validated questionnaires assessing depressive symptoms, and disease- and treatment-related stressors. Data were analyzed using hierarchical linear regression.The model of cumulative number of illnesses was worse at explaining variance in depressive symptoms (Sample 1  = .035; Sample 2  = .029), compared to models including disease- and treatment-related stressors (Sample 1  = .37; Sample 2  = .47). Disease-related stressors were the strongest factor associated with depressive symptoms, specifically, poor subjective cognitive function (Sample 1:  = -.202,  = .013; Sample 2:  = -.288,  < .001) and greater somatic symptoms ( = .455,  < .001; Sample 2:  = .355,  < .001).Using the number of illnesses to understand depressive symptoms in MM is a limited approach. Models that move beyond descriptive relationships between MM and depressive symptoms are needed.Providers should consider the role of somatic symptom management in patients with MM and depressive symptoms.
