This research was done to adapt food frequency questionnaire that includes fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) for Turkish society and assess the validity and reproducibility of this questionnaire. The sample was consisted of 107 healthy participants aged between 19-65. Original questionnaire developed in Australia was used as a model for adaptation. At the first stage, adapted food frequency questionnaire that includes FODMAP for Turkish society was applied. At the second stage, seven-day food records were taken from participants. Eight weeks after the first stage, third stage was implemented, and the adapted food frequency questionnaire was reapplied. To assess the validity, first application of adapted food frequency questionnaire that includes FODMAP for Turkish society and seven-day food records were used whereas data from first and second applications of the adapted questionaire with eight weeks interval were used to assess the reproducibility. General characteristics of participants were recorded. In order to assess the validity, Wilcoxon signed rank test results, Spearman correlation coefficients, Blant-Altman mean differences, data of correctly or misclassified participants and kappa coefficients were presented. Intraclass correlation coefficients were calculated for reproducibility analyses. In terms of validation, when Blant-Altman analyses were considered, adapted questionnaire could determine free fructose, sorbitol, mannitol, raffinose, stachyose, nystose, kestose and total fructan uptake in Turkish society. It was accepted that Blant-Altman mean differences would not affect the clinical results for these components. Results were reproducible for lactose, mannitol, raffinose, stachyose, nystose, kestose and total fructan. When the validation and reproducibility results examined together, adapted food frequency questionnaire that includes FODMAP for Turkish society was found to be a suitable instrument for the detection of mannitol, raffinose, stachyose, nystose, kestose and total fructan intake. Development of the questionnaire is necessary for validity of lactose, fructose and reproducibility of fructose, free fructose and sorbitol. National food analysis is needed to determine the amount of FODMAP components of foods consumed in Turkish society.
