Abstract Aims: i. to estimate psychometric properties of Three-Factor Eating Questionnaire-18 (TFEQ-18), Depression, Anxiety and Stress Scale-21 (DASS-21) and Escala "Perfil do Estilo de Vida Individual" (PEVI) applied in Brazilian university students, ii. to verify relationship among negative affectivity (core concept of depression, anxiety, stress), life style and eating behavior of this students iii. to compare functional performance and body composition in university students with extreme scores of eating behavior. Methods: This study shall take place in two stages. Stage 1: tracking of eating behavior, depression, anxiety, stress, and life style among the students. Also it will be investigate the relationship among negative affectivity, life style and eating behavior's aspects to this sample. Stage 2: recruitment of individuals with extreme scores of eating behavior in order to evaluate their functional performance and body composition. In Stage 1, there should be from 620 to 1.240 participants, students enrolled at a public university. Eating behavior, depression/anxiety/stress and life style shall be investigated using TFEQ-18, DASS-21, and PEVI, respectively. The instruments' psychometric characteristics shall be evaluated by confirmatory factorial analysis (CFA). Factorial, convergent, discriminant validity and reliability shall be estimated. After adjusting the models for the data, they will be test structural models, considering negative affectivity and life style as independents variables and Cognitive Restraint, Uncontrolled Eating, Emotional Eating as dependents variables. The mean scores for each factor of TFEQ-18 shall be calculated to track for extreme scores for Cognitive Restraint, Uncontrolled Eating, Emotional Eating. Scores shall be considered extreme if they are below the 25 (P25) or above the 75 (P75) percentiles of the response scale. Those individuals who agree to participate shall complete the TFEQ-18 again, to confirm their scores. Functional performance (functional neurometry) and body composition (bioimpedance) will be evaluated. The minimum sample size (Stage 2) will be calculated following a pilot study evaluating 5 individuals from each group. Means obtained for each variable (evaluated in functional performance and body composition) will be compared between the groups using Analysis of Variance. Significant variables will be included in the multiple regression model as independent variables and the factors of the TFEQ-18 (cognitive restraint, emotional eating and uncontrolled eating) will be considered dependent variables.
