Health misinformation on social media has led to difficulties in the implementation of public health measures. A questionnaire was developed through literature review, in-depth interviews, expert evaluations, and validated with a cross-sectional survey of 265 active social media users from Malaysia in December 2023. Construct validity was assessed using exploratory factor analysis and internal consistency using Cronbach’s alpha. The final questionnaire consisted of five sections, including 32 items designed to assess knowledge, attitudes, and responses toward health misinformation on social media. Content validity showed satisfactory results, and Cronbach’s alpha value was above 0.7, indicating good internal consistency.
