A comparison of the psychometric properties of three measures of dietary restraint.

A subscale of the Three-Factor Eating Questionnaire (TFEQ), a subscale of the Dutch Eating Behavior Questionnaire (DEBQ), and the Revised Restraint Scale (RS) were administered to 90 1 undergraduates. Test-retest reliability (on 34 subjects) was highest for the RS (r =.95) and roughly equal for the DEBQ (r =.92) and the TFEQ (r =.91). Internal consistency was highest for the DEBQ (α =.95), moderate for the TFEQ (α =.90), and lowest for the RS (α =.82). The DEBQ was the most homogeneous scale, with a single principal component accounting for 68.2% of the variance
