Physical limitations predicting changes in depressive symptoms: mediating effects of pain and social stress. Standardized regression coefficients are shown. N = 1,455. Significant effects for age, gender, race/ethnicity, and socioeconomic status are controlled for in the model but not shown. Model fit: χ2 = 55.91, df = 19; Tucker–Lewis Index = .95; comparative fit index = .99; root mean square error of approximation = .04. Mediation effects using Sobel test: pain, z = 3.03**; chronic stress, z = −0.74; daily discrimination, z = 1.87; recent life events, z = 0.73. W = wave. *p ≤ .05; **p ≤ .01.
