Validación de constructo de escala que mide alfabetización en salud sexual y reproductiva: Validação do construto de uma escala que mede a alfabetização em saúde sexual e reprodutiva.

Methods: Using a pilot test of the scale, in a sample of 375 university students, 3 evaluation stages were implemented. First: evaluation of socio-demographic variables and discriminative capacity of items; through central tendency measures, Mann-Whitney U test, biserial correlation coefficient, floor and ceiling effects and total correlation item in order to eliminate lower discrimination items. Second: reliability evaluation, using McDonald’s Omega and Cronbach’s Alpha. Third: construct validity and convergence; evaluating the model using Confirmatory Factor Analysis (CFA) and convergence test with perception of health condition. Results: The final version has 24 items, 6 for each sub-scale. Reliability is 0.96. CFA validates the suggested model of 4 factors, equivalent to sub-scales: Chi2/gl=2.15, RMSEA=0.056, SRMR=0.037, CFI=0.961, TLI=0.957, NFI=0.931, RFI=0.922, IFI=0.962. Convergence validity is observed. Conclusions: The scale shows validity and reliability, it is short and easy to apply. Advisable for community health diagnoses.http://purl.org/coar/access_right/c_14cbhttps://creativecommons.org/licenses/by-nc/4.0Reproductive Health and Family PlanningHealth LiteracyEvaluation of Health SituationHealth CommunicationArticulohttps://doi.org/10.31052/1853.1180.v28.n2.37423
