OBJECTIVE:To conduct separate factor analyses of the Three Factor Eating Questionnaire (TFEQ-R, TFEQ-D and TFEQ-H) scales and provide initial evidence of the construct validity of the obtained solutions. DESIGN: A cross-sectional survey with a 12 month retest of a subsample of subjects. SUBJECTS: A total of 553 undergraduate university women with a mean age of 25.0 y. The retest sample comprised 64 subjects with a mean age at retest of 25.7 y. MEASUREMENTS: In addition to the TFEQ, age, body mass index (BMI), satisfaction with current weight, nutrition knowledge and current exercise level were recorded. RESULTS: Three restraint (strategic dieting behaviour, attitude to self-regulation, avoidance of fattening foods), three disinhibition (habitual susceptibility, emotional susceptibility, situational susceptibility) and two hunger constructs (internal locus for hunger, external locus for hunger) were identi®ed. Initial evidence of the validity of these constructs was provided. CONCLUSION: The explanation of disordered eating behaviour is likely to be re®ned more by speci®c constructs, such as those presented, rather than by the more general constructs measured by the original TFEQ-R, TFEQ-D and TFEQ-H scales. Further examination of the factor structures presented is therefore encouraged. International Journal of Obesity (2001) 25, 900 ± 906
