Validity and reliability of a questionnaire that aims to investigate consumption and problematic eating behaviours towards refined sugar.

ABSTRACT: This study aimed to develop and validate a questionnaire that investigates sugar-related eating behaviour, excessive consumption, and addictive-like eating. This questionnaire was validated using a rigorous process assessing content validity, face validity, reliability testing, feasibility testing, and construct validity. Spearman's correlation coefficients and Cronbach's alpha were used to assess reliability. Feasibility testing was used to further validate and confirm the scoring/categorisation of 'low', 'medium', and 'high' scorers for use in future research. Exploratory factor analysis and reliability analysis were used to determine underlying latent factors and assess construct validity. Content validity was assessed by health professionals (n = 16), face validity was assessed
