Abstract

OBJECTIVE

The Repetitive Eating Questionnaire (Rep(eat)-Q) is a brief self-report measure developed to assess grazing behavior-an understudied problematic eating behavior associated with eating disorder psychopathology and poor weight management. This study aimed to adapt and test the psychometric properties and factor structure of the Rep(eat)-Q in a Brazilian community sample.

METHOD

We used the International Test Commission guidelines for the adaptation of psychological measures between cultures. Participants were recruited from the community and on a university campus and completed a set of questionnaires including the Rep(eat)-Q, psychological measures, and sociodemographic data.

RESULTS

A total of 718 (86.4% female) completed the Rep(eat)-Q and were eligible for the confirmatory factor analysis (CFA). Only 542 completed the entire survey (Rep(eat)-Q and other psychological measures) and were eligible for the analysis of the validity evidence based on the relations to other variables. CFA revealed support for a two first-order model as originally proposed, however, a hierarchical (i.e., second-order) model is proposed. We found support for second-order scalar invariance across sex. Both first- and second-order internal consistency estimates presented very good evidence. Analysis (n = 542) revealed moderate to strong correlations (≥.58 to .77) between grazing (total score and subscales) and binge eating and other psychological measures, presenting good convergent evidence.

DISCUSSION

This study reports good psychometric properties of the Rep(eat)-Q for the Brazilian community sample.

PUBLIC SIGNIFICANCE

Grazing is a problematic eating behavior and the Rep(eat)-Q is one of the measures to assess grazing. The article aimed to adapt and test the psychometric properties of the Rep(eat)-Q in a Brazilian community sample. The results support a two-factor structure and suggest that the Rep(eat)-Q possesses good psychometric properties to be used with the Brazilian populations.

摘要

目的

重复进食问卷（Rep(eat)-Q）是一种简短的自我报告测量工具，旨在评估随意进食行为——一种研究较少的问题性进食行为，与饮食失调心理病理学和体重管理不善相关。本研究旨在对Rep(eat)-Q进行改编，并在巴西社区样本中测试其心理测量特性和因子结构。

方法

我们采用了国际测试委员会关于跨文化改编心理测量工具的指南。参与者从社区和大学校园招募，完成了一系列问卷，包括Rep(eat)-Q、心理测量工具和社会人口统计学数据。

结果

共有718人（86.4%为女性）完成了Rep(eat)-Q并符合验证性因子分析（CFA）的条件。只有542人完成了整个调查（Rep(eat)-Q和其他心理测量工具）并符合基于与其他变量关系的效度证据分析条件。CFA显示支持最初提出的两因素一阶模型，然而，我们提出了一个层次模型（即二阶模型）。我们发现支持跨性别的二阶标量不变性。一阶和二阶内部一致性估计均提供了非常好的证据。分析（n = 542）显示随意进食（总分和子量表）与暴饮暴食及其他心理测量工具之间存在中度至强相关性（≥.58至.77），提供了良好的聚合效度证据。
