Note. Unstandardized estimates and standard errors are presented. Intercept is centered at one year prior to death; rate of change is scaled in T-units per year as per the annual assessment schedule in the SOEP. N = 2,910 participants who provided 33,777 observations. Scores were standardized to a T metric (M = 50; SD = 10) using the 2002 SOEP sample as the reference frame (M = 6.90, SD = 1.81 on a 0–10 scale). Two-way interaction terms of the quadratic slope and of social resource variables were tested, but only those statistically significantly different from zero were retained in the final model. AIC = Akaike Information Criterion, a relative model fit statistic.
