Data set for the Three-Factor Eating Questionnaire validation

This dataset was collected due to the Three-factor eating questionnaire (TFEQ) validation in the Russian sample and composed of three groups. All data were collected from university students in Stavropol Krai, Russia, and primarily studied at the North-Caucasus federal university. Respondents were surveyed in 2019-2020 years. The data includes results from 3 samples: (1) The main (experimental group) of 213 respondents. They were surveyed by: a. The unified version of TFEQ (51 items, TFEQ-51-Ru-mod). This version was radically shortened through structural equation modeling (SEM) to the validated model of 15 items (TFEQ-Ru15) with quite better psychometric characteristics b. Morosanova’s Self-Regulation Profile Questionnaire (SRQM, in Russian) was used for assessing cognitive-operational competencies and regulatory-personal features: goals planning, modeling of significant conditions, programming of actions, estimation of results, regulatory flexibility, and independence. All features were considered as possible predictors of eating behavior. c. The Russian shortened version of the Perceived Stress Scale (Cohen et al., 1983; Cohen & Williamson, 1988). Data from first and second control groups were collected only for obtaining psychometric characteristics of the most common TFEQ versions. (2) Control group of 669 respondents provided data for 18-items TFEQ version, TFEQ-18-2004 (de Lauzon, B., Romon, M., Deschamps, V., Lafay, L., Borys, J.-M., Karlsson, J., Ducimetière, P., Charles, M. A., & Fleurbaix Laventie Ville Sante (FLVS) Study Group. (2004). The Three-factor eating questionnaire-R18 is able to distinguish among different eating patterns in a general population. The Journal of Nutrition, 134(9), 2372–2380. https://doi.org/10.1093/jn/134.9.2372) translated in Russian by native speakers. (3) Control group of 301 respondents provided data for the original 51-items TFEQ, invented by Stunkard & Messick (1985), translated into Russian by native speakers. So, the file dataset.xlsx contains sheets: - Respondents’ answers in numbers for every item of TFEQ-51-Ru-mod (for SEM, 213 respondents) - Scales values of TFEQ-Ru15, SRQM, and Perceived Stress Scale (for correlation analysis, 213 respondents) - Respondents’ answers in numbers for every item of TFEQ-18-2004 (669 respondents) - Respondents’ answers in numbers for every item of TFEQ-51-unst-intl (301 respondents) Other files content some results: Cronbach's alpha.xlsx This file contains scrutinized results of assessing Cronbach's alpha for all these diagnostic techniques. validation group correlations.xlsx This file contains detailed results for Rank order correlations between scales of TFEQ-Ru15, SRQM, and Perceived Stress Scale (experimental sample of 213 respondents) SEM.zip This archive contains files of structural models for all four TFEQ techniques: TFEQ-Ru15, TFEQ-51-Ru-mod, TFEQ-18-2004, and TFEQ-51-unst-intl, performed in IBM SPSS Amos 23.0. The datafiles for these models as Excel files situated in the same folders.

本数据集为开展俄罗斯样本下三因素饮食问卷（Three-factor eating questionnaire, TFEQ）的验证研究而采集，共包含三组数据。所有数据均采集自俄罗斯斯塔夫罗波尔边疆区的大学生，主要就读于北高加索联邦大学，调查于2019-2020年间开展。

本数据集包含三类样本数据：
(1) 核心实验组：共213名被试。采用以下三类工具开展调查：
a. 三因素饮食问卷俄文精简版（TFEQ-51-Ru-mod）：该版本通过结构方程模型（Structural Equation Modeling, SEM）从原51题大幅精简为15题的验证模型（TFEQ-Ru15），具备更优异的心理测量学特性。
b. 莫罗萨诺夫自我调节概况问卷（Self-Regulation Profile Questionnaire, SRQM，俄文版）：用于评估认知操作能力与调节-人格特征，包括目标规划、关键情境建模、行动编程、结果评估、调节灵活性与独立性，上述特征均被视为饮食行为的潜在预测因子。
c. 感知压力量表（Perceived Stress Scale, PSS）俄文精简版，该量表最早由Cohen等人于1983年提出，后经Cohen与Williamson于1988年完善。
前两个对照组的数据仅用于验证主流TFEQ版本的心理测量学特性。

(2) 第一对照组：共669名被试，其数据来自18题版三因素饮食问卷TFEQ-18-2004。该版本由de Lauzon等人于2004年开发，可区分普通人群中的不同饮食模式，经母语为俄语的研究者翻译为俄文。

(3) 第二对照组：共301名被试，其数据来自Stunkard与Messick于1985年开发的原版51题TFEQ，该问卷经母语为俄语的研究者翻译为俄文。
