	Disability Group
Negative Exchange Group	Absent	Low Remitter	Increaser
Absent	.58***	.31***	.11**
Chronically low	.35***	.65***	.00
Moderate increaser	.04	.71***	.25**

Notes: Individual trajectories for disability and positive exchanges were adjusted for the following covariates: gender (0 = male, 1 = female), age, ethnicity (0 = ethnic minority, 1 = White), marital status (0 = unmarried, 1 = married), education level (0 = high school/vocational school or less, 1 = at least some college), total number of 12 possible health conditions (e.g., arthritis or rheumatism, hypertension, diabetes), weight, and level of engagement in light or moderate physical activities (e.g., walking, light gardening) (0 = never, 6 = daily).
