Validation of an adolescent ovulatory menstrual health literacy questionnaire.

This study aimed to face validate an adolescent ovulatory menstrual (OM) health literacy questionnaire and to measure reliability by test-retest. Draft questions from an earlier content validation were adjusted following face validity assessment with 28 adolescents. Test-retest reliability was assessed by 89 adolescents aged 14-18 years over a two-week period across four school sites. The mean levels of agreement recorded from the critical, interactive and functional health literacy domains were 83%, 74% and 68%, respectively. There were 44 out of 74 items with Kappa statistics >0.40. The questionnaire has confirmed face validity and adequate test-retest reliability for assessing adolescent OM health literacy.
