Abstract

Background: The aim of the study was to examine the construct validity of the Three-Factor Eating Questionnaire -R18 (TFEQ-R18), a measure of eating behaviour, and to evaluate cognitive restraint, uncontrolled eating and emotional eating in a sample of adolescent and young adult females of different weights.Methods: Subjects were 2 997 females, aged 17 to 20 years, who participated in a phase III human papillomavirus vaccination trial in Finland in 2004 - 2009.Self-administered questionnaires and weight and height measurements were used. The factor structure of the TFEQ-R18 was verified by factor analysis. Connections between measured eating behaviour and Body Mass Index (BMI) were tested using analysis of variance.Results: The original factor structure of the TFEQ-R18 was replicated: six of the eighteen items measured cognitive restraint, nine measured uncontrolled eating, and three measured emotional eating. On average, higher BMI was associated with higher levels of cognitive restraint (p < 0.001) and emotional eating (p < 0.001), but not with uncontrolled eating.Conclusion: Structural validity of the TFEQ-R18 was good in this sample of young Finnish females with a varying range of body weights. Use of the instrument as a measure of eating behaviour was thus corroborated. Connections of restrained and emotional eating with BMI were in accordance with previous findings from young females. © 2009 Anglé et al; licensee BioMed Central Ltd.
