Abstract

This study aims to cross-culturally adapt the Dietary Goal-Desire Incongruence Scale (DG-DI), Motivation for Dietary Self-Control Scale (MDSC), and Satisfaction with Dietary Behavior Scale (SWDB) into Portuguese; to evaluate data validity and reliability; and to analyze the dietary desire-goal incongruence, motivation for dietary self-control, and satisfaction with dietary behavior among Brazilian adults. This is a cross-sectional study. Data were collected online from adults aged 18-35 years. The validity (content, internal structure, external measures, item response and consequential) and reliability of data were assessed. The scores of instruments were compared according to sample characteristics by Student's t-test (alpha = 5%). 1,921 people participated (age = 24.9 years [standard deviation = 4.6]; 74.2% women). The validity and reliability of the DG-DI and SWDB have been attested as originally proposed. For MDSC one item was removed ("& mldr;doctor recommendations"). Women (t=-6.84 & horbar;5.28), and those who consider their eating as regular/poor (t=-32.96 & horbar;15.42) showed greater dietary incongruence, greater external motivation to eating control and lower satisfaction with eating (P < 0.001). The Portuguese versions of DG-DI, MDSC, and SWDB were established. Data were valid and reliable. Sample characteristics were associated with desire-goal incongruence, motivations to regulate eating, and satisfaction with eating, which are important in assessing people's eating behavior. (AU)
