Abstract

OBJECTIVE: To develop and validate the Menstrual Disorder of Adolescent (MenDA) Questionnaire to assess knowledge, attitude, and practise (KAP) of adolescents towards menstrual disorder. STUDY METHOD: The questionnaire was developed following a standardised protocol that consisted of literature review, focused group discussions, and expert opinion. It was subjected to content validity by six experts and face validity by 46 adolescents before a revised final version was drafted. Then, a cross-sectional survey on 485 adolescents was carried out to validate the tool. The MenDA questionnaire was administered using Google form and consist of three domains: Knowledge (35 items), attitude (23 items), and practice (23 items). Exploratory factor analysis (EFA) was performed using a principal component with varimax rotation to establish the construct validity of the questionnaire. The internal consistency of the questionnaire was tested using Cronbach's alpha coefficient. RESULT: MenDA questionnaire with 62 items categorised under three domains knowledge, attitude, and practices was developed. The knowledge , attitude and practice (KAP) sections have 23, 18, and 21 items, respectively. Independent Cronbach's alpha for KAP domains were 0.739, 0.711, and 0.793, respectively, indicating good internal consistency. CONCLUSION: Evidence of validity and reliability of the MenDA questionnaire has been obtained and can be used to assess KAP on menstrual disorders among Malaysian adolescents.
