Adaptation of the contraceptive self-efficacy scale for heterosexual Mexican men and women of reproductive age

The Spanish Version Contraceptive Self-efficacy scale has an acceptable Cronbach alpha. Exploratory factor analysis identified 7 components. A positive correlation between self-reported contraceptive self-efficacy and family planning method use was identified. This scale may be used among heterosexual Mexican men and women of reproductive age. The factor analysis (7 factors versus 4 factors for the original scale) identified a discrepancy for interpretation of the Spanish versus English language versions. Interpretation of findings obtained via the Spanish versión among heterosexual Mexican men and women of reproductive age require interpretation based upon these differences identified in these analyses.
