validity and reliability evaluation of the dietary habits scale for adults (25-55 years old) derived from iranian traditional medicine

Background: currently, a healthy lifestyle that also covers eating habits plays a vital role in the prevention of many diseases, especially chronic diseases. these habits have been precisely classified in the texts of iranian traditional medicine. these classifications help better understand and make better use of food, which can be confirmed with new tools and information. this study aimed to evaluate the validity and reliability of dietary habits scale for adults derived from iranian medicine.methods: this cross-sectional study was designed to develop the dietary habits scale and evaluate its validity and reliability. the scale was drafted with two subscales including eating manners and drinking manners based on the principles of iranian medicine. afterward, to determine the construct validity and reliability of the scale, it was administered to 40 people aged 25 to 55 years. data were analyzed using spss21 and amos software.results: the content validity ratio (cvr) and content validity index (cvi) were 0.99 and 0.79, respectively. the confirmatory factor analysis (cfa) test was used to evaluate its dimensionality. the cfmin/df was 1.80, and rmsea, gfi, and cfi were 0.05, 0.91, and 0.93, respectively. the internal consistency of the scale was confirmed by calculating the cronbach’s alpha coefficient (α = 0.805).conclusion: the eating habits scale developed based on the iranian medicine has acceptable reliability and validity for its administration on the participants. in future studies, researchers are recommended to focus on different demographic groups and examine the impact of contextual and clinical variables.
