aMean number of months between baseline and follow up survey is 17.9 (SD = 4.2; range = 11.1–24.0 months; IQR = 13.6–22.1 months). Two-sample t-test was used for age and years of schooling. Chi-square test was used for gender, race, marital status, highest degree, employment, and recruited at VA. Wilcoxon rank-sum test was used for all others
