The objective of this study was to design a weight loss self-efficacy questionnaire which was multidimensional, with each dimension representing a specific type of relapse situation. The instrument developed contained 41 specific situations or emotional states which were considered to be high-risk for precipitating diet relapse. Two hundred thirty-six usable questionnaires were completed by individuals who attended a weight reduction class at one of eleven Air Force bases in the continental United States. Exploratory principal component analysis using the varimax, rotation method was employed to test for the presence of distinct dimensions of self-efficacy. Three distinct dimensions emerged, Negative Emotional, Urges and Temptations, and Party Situations, which accounted for approximately 56 percent of variance. Reliability coefficients ranged from.96 to.84 indicating that the sampling attributes for the three domains were adequate and there was homogeneity of items constituting each dimension. An instrument of this type has the potential for improving effectiveness of weight reduction therapies by facilitating the targeting of intervention to the situations identified as being high-risk for a specific person.
