Abstract
OBJECTIVE
To examine the relationship between self-related agency beliefs and observed eating behavior in adolescent girls with loss of control (LOC) eating.
METHOD
One-hundred eleven adolescent girls (14.5 ± 1.7 years; BMI: 27.1 ± 2.6 kg/m(2)) were administered the General Self-Efficacy Scale and the Weight Efficacy Lifestyle Questionnaire (WEL). Adolescents then participated in a laboratory test meal.
RESULTS
Greater general and eating self-efficacy were associated with fewer episodes of LOC eating. General self-efficacy was inversely related to total intake at the meal (p < .01). Only the WEL availability subscale score, but not the other WEL subscales, was inversely related to total energy, snack, and dessert intake (ps < 0.05).
DISCUSSION
General self-related agency beliefs may be important in relation to energy consumption. Among girls susceptible to disordered eating and obesity, the domain-specific belief in one's ability to refrain from eating when food is widely available may be especially salient in determining overeating in the current food environment. Further research is therefore needed to assess the predictive validity of these beliefs on eating and weight outcomes.
