To assess response reliability, we examined agreement between couples in heterosexual HIV sero-discordant partnership on survey questions regarding condom use and sexual decision-making.Methods Data for this analysis come from baseline data from a cohort study of HIV sero-discordant couples in Jinja, Uganda. We examined the degree of agreement between male and female partners on standard measures of sexual behaviour using the kappa (κ) statistic and 95\% confidence intervals (95\% CIs).Results Among 409 couples, the median age for the male partner was 41 [interquartile range (IQR) 35{\textendash}48] years and the female partner was 35 (IQR 30{\textendash}40) years. Among 58.2\% of the couples, the male was the HIV-positive partner. Questions with high or substantial couple agreement included condom use at last sex (κ=0.635, 95\% CI 0.551{\textendash}0.718) and frequency of condom use (κ=0.625, 95\% CI 0.551{\textendash}0.698). Questions with low or fair couple agreement included decision-making regarding condom use (κ=0.385, 95\% CI 0.319{\textendash}0.451), wanting more biological children (κ=0.375, 95\% CI 0.301{\textendash}0.449) and deciding when to have sex (κ=0.236, 95\% CI 0.167{\textendash}0.306).Conclusions Survey questions assessing condom use had the highest level of couple agreement and questions regarding sexual decision-making and fertility desire had low couple agreement. Questions with high agreement have increased reliability and reduced measurement bias; however, questions with low agreement between couples identify important areas for further investigation, particularly perceived relationship control and gender differences.}, issn = {1471-1893}, URL = {https://srh.bmj.com/content/43/2/142}, eprint = {https://srh.bmj.com/content/43/2/142.full.pdf}, journal = {BMJ Sexual \& Reproductive Health} }
