Notes: Correlation coefficients (corr. coeff.) were calculated for age, month of first sex and duration variables, and kappa coefficients for all others. Kappa categories: weak, 0.00–0.20; fair, 0.21–0.40; moderate, 0.41–0.60; substantial, 0.61–0.80; strong, 0.81–1.00. No married men suspected their wife of having a nonmarital partner. na=not applicable.
