ABSTRACT

Objective: to determine the reliability and construct validity of an attitudes & opinion assessment scale about the contraceptive methods in women of 14 Latin American countries.
Material and methods: Design: descriptive, cross-sectional, observational study. Population: 7,456 women from 14 to 45 years of age. Sampling: randomized, multiple step with proportional representativeness, stratified by age. Variables: 256 variables, 21 explored attitudes and opinions about the contraceptive methods. Measurements: Likert scale (5 options); 284 professional enabled pollsters participated. Instrument: Closed questionnaire, technique of direct domiciliary interview. Analysis: Coefficient of reliability Cronbach's alpha and factorial exploratory analysis.
Results: Attitudes: Cronbach’s alpha = 0.875. The factorial analysis obtained a main component which explains 50.3% of variance. Opinions: Cronbach’s alpha = 0.675. The factorial analysis showed three factors explaining 45.4% of the variance.
Conclusions: The high reliability and the construct validity in enough minimal values about attitudes and opinions regarding contraceptive methods, showed that the questionnaire explores one construct. The questionnaire is brief and f easy application for medical practice.
