Notes: N = 779 who provided 1,848 observations. The occasion column indicates the years before, at, and after the onset of disability, with 0 representing the measurement occasion where the onset of disability was first noted. The −1 through −8 occasions represent the predisability phase (−1 indicating a measurement occasion taken 1 year prior to the onset of disability). The 1 through 8 occasions represent the postdisability phase (1 indicating a measurement occasion taken 1 year after the onset of disability). Scores for depressive symptoms standardized to a T metric (M = 50; SD = 10) using the pooled sample of all participants at baseline assessment T1 as the reference (N = 1,440).
