![]() ‘There is increasing clarification that the core psychopathology, a morbid fear of fatness and/or a relentless drive for thinness, is not a delusional belief nor an ego-alien symptom but an overvalued belief-an intriguing, little studied theory’ (Andersen, 2001, p. This may reflect excessive fear of gaining weight rather than decreased ability to experience pleasure’. ‘We conclude that the hedonic responses to sucrose in patients with eating disorders are decreased when solutions are swallowed. Social Anhedonia but not Physical Anhedonia correlated positively with ‘Drive for Thinness’ and ‘fear of swallowing sucrose solutions’, and correlated inversely with maximal hedonic response to the ‘swallow’ condition. When ‘Drive for Thinness’ on the Eating Disorder Inventory was included as a covariate, similar results were obtained. When ‘fear to swallow’ sucrose solution responses were included as a covariate, the significant difference between the conditions of ‘swallow’ or ‘spit’ disappeared, but there was a significant concentration by condition by fear to swallow interaction and an almost significant covariate effect. There was a significant effect of sucrose concentrations as well as a significant condition by concentration interaction. The hedonic response to sucrose adjusted for the sweet taste perception threshold was significantly lower in the ‘swallow’ than in the ‘spit’ condition. The threshold concentration of sweet taste perception was also assessed, and the subjects filled out Chapman's Social and Physical Anhedonia Scale. The two test conditions were randomly administered. Under double-blind conditions and according to a Latin square design, patients received sucrose in solution (0, 5, 10, 20, and 40%) and rated each concentration for pleasantness on a nine-point scale. We therefore compared the hedonic responses to sucrose solutions in B, RA and AB women ( n =20/group) in two different conditions: sucrose solution swallowed vs. We hypothesized that this response could be linked to an excessive fear of weight gain rather than a decreased ability to experience pleasure. Previous research has shown that patients with bulimia nervosa (B), anorexia nervosa, restricting type, or restrictive-anorectic (RA), and anorexia nervosa, binge eating, purging type, or anorectic–bulimic (AB) exhibit a reduced hedonic response to sucrose compared with control subjects. ![]()
