Abstract

Healthy lifestyle behavior is the main asset in dealing with various health issues, including for people in the Islands region. Healthy lifestyle behavior implementation must be based on scientific knowledge. An instrument is needed to measure students’ healthy lifestyle behaviour-related science knowldge and students’ lifestyle behavior. This research aims to determine the content validity of the instrument for measuring science knowledge related to healthy living behavior and students’ healthy lifestyle behaviour. This research was quantitative descriptive. The instrument was developed based on 8 main indicators including physical activity, nutritious food consumption, sleep duration, cigarette and alcohol consumption, use of clean water, hand washing habits, use of bathrooms and toilets, and waste disposal culture. The instrument was validated by 8 experts and analyzed using the Aiken Formula (V). The results of this validity test showed that the instrument was valid for aspects of relevance and presentation (V = 0.96), accuracy of language (V = 0.88), and conformity with conceptual and operational definitions (0.94). These results indicate that the instrument can be continued with empirical validity and reliability tests until a valid and reliable instrument is obtained.
