Abstract: | Tested several aspects of restraint theory using 89 female college students in a 2–3 between-Ss design. The ice cream consumption of overweight and normal-weight restrained and unrestrained eaters was measured during a taste test. Prior to the taste test, half the Ss received a milkshake preload. Results reveal significant Weight by Restraint, Weight by Preload, and Restraint by Preload interactions. Unrestrained eaters consumed less after the preload than without it, whereas restrained eaters ate more. Overweight Ss ate less after the preload than without it, whereas normal-weight Ss ate slightly more. Among overweight Ss, unrestrained eaters ate more than restrained eaters, whereas among normal-weight Ss, the reverse was true. The significant Weight by Preload and Restraint by Preload interactions possibly reflect psychometric problems in the restraint scale. Numerically equivalent scores may indicate less "true" restraint in overweight than in normal-weight Ss. (17 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
