The present study expanded upon current research on risk factors for eating pathology by exploring the predictive power of and correlations between variables of social comparison and competition with a sister. Seventy-one women responded to measures of general social comparison, social comparison with a sister, physical-appearance-related social comparison, general competitiveness and competitiveness with a sister, as well as a measure of eating pathology. The results suggest that competitiveness with a sister and physical-appearance-related social comparison are correlated with eating pathology. In addition, competitiveness with a sister is a significant predictor of eating pathology, and explained 30% of the variance in eating pathology in this sample. Implications for treatment and assessment are discussed.
