Adaptation of three factor eating questionnaire (TFEQ-R21) into
Turkish culture: A validity and reliability study

Abstract Objectives: Obesity is a serious public health issue. Investigating the eating behaviour of individuals plays an important role in preventing obesity. Therefore, the purpose of the current study is to adapt the long and first version of the ‘Three-Factor Eating Questionnaire’ (TFEQ), a scale that examines the eating behaviour of individuals, to Turkish culture and to carry out its validity and reliability study. Design: The data were collected using data collection forms, and anthropometric measurements of the individuals were made by the researchers. The data collection form included several parameters: socio-demographic characteristics, the TFEQ scale, whose validity and reliability analysis is conducted here, and the Dutch Eating Behaviour Questionnaire (DEBQ) which was used as a parallel form. Setting: The Obesity Clinic at Ege University in Izmir. Participants: The study group consisted of obese adult individuals (n 257). Results: It was seen that constructing the questionnaire with twenty-seven items and four sub-dimensions provides better information about Turkish obese individuals. Factor loadings ranged from 0·421 to 0·846, and item total score correlations ranged from 0·214 to 0·558. Cronbach’s α coefficient was found to be 0·639 for the whole scale. A positive, strong and statistically significant correlation was detected between TFEQ and DEBQ, which was used as a parallel form (r = 0·519, P < 0·001). Conclusion: In Turkey, the long version of the TFEQ scale was found valid and reliable for obese adult individuals. TFEQ can be used by clinicians or researchers to study the eating behaviour of obese individuals.

The purpose of this study was to adapt "Online Privacy Concern Scale" developed by Buchanan, Paine, Joinson and Reips (2007) to Turkish culture. The original version of the scale was composed of 16 items gathered under a one-factor structure. During the translation process, expert opinions were taken for the language validity. The scale was pre-administered to 40 participants to pursue linguistic equality. To determine the validity and reliability evidence of the scale, it was administered to two separate groups consisting of adult Internet users. In order to examine and confirm the scale structure, exploratory and confirmatory factor analyses (EFA and CFA) were conducted. After eliminating two items, EFA showed that the scale had a three-factor structure (email usage, online trust and online payment) in Turkish culture. The Cronbach's Alpha internal consistency of the whole scale was .89. In addition, CFA verified the three-factor solution. The results of the current study confirmed that the Turkish version of the scale is a valid and reliable measurement tool for the assessment of online privacy concern of adult Internet users.

Abstract: Introduction: Eating behaviours play a crucial role in the development of obesity. Aims: To conduct a psychometric analysis of the Three-Factor Eating Questionnaire–R21 and to investigate the correlates of obesogenic eating behaviours among males. Method: Participants of the cross-sectional questionnaire-based study were male university students (n = 239, mean of age: 20.3 years, SD = 2.78 years). Measures: self-reported body weight and body height, Three-Factor Eating Questionnaire–R21, Trait Anxiety Scale of the State-Trait Anxiety Inventory. Results: Results of confirmatory factor analysis supported the theoretical model of the Three-Factor Eating Questionnaire–R21 (χ2(186) = 366.1, p<0.001, CFI = 0.959, TLI = 0.954, RMSEA = 0.064). Internal consistency of the scales was adequate (Cronbach’s α: 0.79–0.88). Body Mass Index and trait anxiety showed significant, positive associations with eating behaviours, such as uncontrolled eating, cognitive restraint, and emotional eating. Conclusions: Results support the construct validity and reliability of the Three-Factor Eating Questionnaire–R21 among males and highlight the importance of taking psychological factors into account in the prevention of obesity.

AbstractObjectiveTo examine score validity and reliability of a child version of the twenty-one-item Three-Factor Eating Questionnaire (CTFEQ-R21) in a sample of Canadian children and adolescents and its relationship with BMI Z-score and food/taste preferences.DesignCross-sectional study.SettingSchool-based.ParticipantsChildren (n 158), sixty-three boys (mean age 11·5 (sd 1·6) years) and ninety-five girls (11·9 (sd 1·9) years).ResultsExploratory factor analysis revealed that the CTFEQ-R21 was best represented by four factors with item 17 removed (CFFEQ-R20), representing Cognitive Restraint (CR), Cognitive Uncontrolled Eating (UE 1), External Uncontrolled Eating (UE 2) and Emotional Eating (EE), accounting for 41·2 % of the total common variance with good scale reliability. ANOVA revealed that younger children reported higher UE 1 and CR scores than older children, and boys who reported high UE 1 scores had significantly higher BMI Z-scores. Children with high UE 1 scores reported a greater preference for high-protein and -fat foods, and high-fat savoury (HFSA) and high-fat sweet (HFSW) foods. Higher preference for high-protein, -fat and -carbohydrate foods, and HFSA, HFSW and low-fat savoury foods was found in children with high UE 2 scores.ConclusionsThe study suggests that the CFFEQ-R20 can be used to measure eating behaviour traits and associations with BMI Z-score and food/taste preferences in Canadian children and adolescents. Future research is needed to examine the validity of the questionnaire in larger samples and other geographical locations, as well as the inclusion of extraneous variables such as parental eating or socio-economic status.
