Analyses were adjusted for age

Session attendance analyses

^aFor the binary outcomes (i.e., any marital condom use and condom use at last sex) the corresponding estimates represent odds ratios

^bThe effects in the full model were tested by type III F tests for fixed effects whereas the simple main effects were tested for the differences in least squares means by using t tests

^cFor subsample of participants reporting marital sex in the past 90 days (n = 196)
