The intake of sugar-sweetened beverages (SSBs) and snacks have changed and has associated with weight gain in children. However, it is challenging to measure the consumption of SSBs and snacks due to the limitation of existing tools. Aimed for this study was to develop and validate the beverages and snacks questionnaire for schoolchildren (BSQ-C). In testing for internal consistency, the value of Cronbach’s alpha indicated that more than 0.70 is considered an acceptable internal consistency. In conclusion, the BSQ-C developed is valid and reliable to measure the pattern and behaviour of SSBs and snacks intake among schoolchildren.
