Main Article Content
Abstract
Background: Assessing balanced nutrition knowledge and eating behavior among adolescent girls is important because they affect health and nutritional status, thus it needs measurement instruments that have been tested for validity and reliability.
Objective: To assess the validity and reliability of balanced nutrition knowledge and eating behavior questionnaires among adolescent girls.
Method: This study involved 30 Senior High School girls aged 15-18 years. The validity of the data was tested using difficulty level analysis, differentiating power analysis, distractor analysis, Lawshe's Content Validity Ratio (CVR) analysis, and item discrimination test. The reliability of the questionnaire was tested using Cronbach's Alpha coefficient.
Results: A total of 20 items regarding balanced nutrition knowledge were considered valid and 10 items about eating behavior were declared valid. The results of the reliability test of the questionnaire on balanced nutrition knowledge and eating behavior obtained Cronbach's Alpha values of 0.822 and 0.829, thus this questionnaire is declared reliable.
Conclusion: The questionnaire on balanced nutrition knowledge and eating behavior has good validity and reliability values. The questionnaire can be used to obtain accurate and consistent data in order to assess the balanced nutrition knowledge and eating behavior among adolescent girls.
KEYWORDS: Nutritional knowledge, eating behavior, validity, reliability.
