Development, and Validation of a Triple Benefit Health Education Intervention Module and Questionnaire to Improve Adolescent Girls’ Knowledge, Attitude, and Practice Toward Malnutrition

Background: Malnutrition among adolescent girls in conflict-affected regions of Nigeria remains a pressing public health concern. Method: This study developed and validated the Triple Benefit Health Education Intervention Module and a corresponding questionnaire to improve knowledge, attitude, and practice (KAP)  toward malnutrition. The questionnaire was adapted from established nutrition assessment tools and validated through expert review and face validity testing among adolescent girls. Reliability was confirmed via Cronbach’s alpha and test-retest analysis. The module underwent rigorous face and content validation, achieving a 93% content validity score. An Independent t-test (student test) was used to compare the means of two groups of continuous variables. Result: A pilot study involving 43 adolescent girls demonstrated significant improvements in knowledge, attitude, practice, information, motivation and behavioural skill scores in the post-intervention test, with mean knowledge rising from 6.3 to 26.4 (p-<0.001), attitude from 44.1 to 71.9 (p-<0.001), and practice from 35.6 to 45.0 (p-<0.001). Conclusion: These results underscore the effectiveness of the module and questionnaire in promoting nutritional awareness and behavior change. The validated tools offer a promising framework for scaling adolescent health education interventions in similar settings.
