Note. Entries in parentheses reflect between-year variance in a respective RPWB dimension based on adjusted R2 (i.e. the proportion of the variance explained by wave). The ages listed refer to 1993-1994 in the WLS and 1995 in MIDUS. Downward arrows denote a statistically significant decline in a respective dimension; upward arrows denote a statistically significant increase; the absence of an arrow indicates that this RPWB dimension has not changed significantly between the two waves. Asterisks denote significant differences in means:
*
p < 0.05;
**
p < 0.01;
***
p < 0.001.
