OBJECTIVE: To evaluate test-retest reliability of social network-related information of the" Pró-Saúde" study. METHODS: A test-retest reliability study was conducted using a multidimensional questionnaire applied to a cohort of university employees. The same questionnaire was filled out twice by 192 non-permanent employees with two weeks apart. Agreement was estimated using kappa statistics (categorical variables), weighted kappa statistics, log-linear models (ordinal variables), and intraclass correlation coefficient (discrete variables). RESULTS: Estimates of reliability were higher than 0.70 for most variables. Stratified analyses revealed no consistently varying patterns of reliability according to gender, age or schooling strata. Log-linear modelling showed that, for the study ordinal variables, the model of best fit was "diagonal agreement plus linear by linear association". CONCLUSIONS: The high level of reliability estimated in this study suggests that the process of measurement of social network-related aspects was adequate. Validation studies, which are currently being conducted, will complete the quality assessment of this information.
