Using General Social Survey data from 1991–2022, I examined reported sex with someone other than a spouse while married by frequency of religious-service attendance and sex. The analysis included 13,599 respondents with valid unweighted counts: 6,579 men and 7,020 women. Percentages were weighted using WTSSPS.
Men reported infidelity more often than women in every attendance category. Weighted percentages ranged from 13.6% to 25.4% for men and from 10.0% to 20.2% for women. For both groups, reported infidelity generally declined as attendance became more frequent, though the pattern was not strictly monotonic. The highest percentages for both men and women were among those attending less than once a year.
Weighted Spearman correlations were small but statistically significant: men, ρ = −.084, p < .001 (n = 7,287); women, ρ = −.101, p < .001 (n = 6,552). Thus, more frequent attendance was associated with a slightly lower likelihood of reporting infidelity in both groups. These correlations do not show that attendance causes the difference, and the separate results do not establish whether the association differs significantly between men and women.
