The Cash effect: Shaping the research conversation on body image and eating disorders.

Cash and Deagle (1997) examined the associations between body image disturbance (BID) and the eating disorders (EDs) of anorexia nervosa (AN) and bulimia nervosa (BN) in a meta-analytic review. They found almost twice as many studies employing perceptual measures of body size evaluation compared to cognitive-evaluative measures of body dissatisfaction, even though effect sizes were larger for studies with cognitive-evaluative measurement. We examined 109 "influential" (i.e., well-cited) studies that cited the Cash and Deagle meta-analysis. We found a slight, continued emphasis on research using body size evaluation measures that implied a biological correlate for perceptual differences (especially for those with AN). We found proportionally more studies using cognitive-evaluative measures than was true in 1997, and more variability in the types of measures used. In these studies researchers emphasized the role of sociocultural factors in the link between BID and EDs. Theory and research that integrate a variety of factors to conceptualize the association between BID and EDs are still needed.
