Situational dieting self-efficacy and short-term regulation of eating.
The Situation-Based Dieting Self-Efficacy Scale (SDS) measures dieters' beliefs in their abilities to adhere to a diet in eating situations. The scale has high internal consistency and test-retest reliability. Female dieters were recruited who were either high or low on SDS, and assigned either to consume a high calorie preload or to a no preload condition. Subjects with high SDS ate less in a subsequent "taste rating" task than subjects with low SDS. Amount eaten was not predicted by hunger, weight, palatability, mood, or restrained eating style. This finding challenges the tendency to view all dieters as equally likely to lapse in response to dietary challenges.
