Hedonic hunger, the appetitive drive to eat to obtain pleasure in the absence of an energy deficit, is associated with overeating and with loss of control over eating, but has not been investigated among individuals with eating disorders.
(1) to compare participants with anorexia nervosa, restricting type (AN-R), anorexia nervosa, binge-purge type (AN-B/P), and bulimia nervosa (BN) on scores on the Power of Food Scale (PFS), a self-report measure of hedonic hunger; (2) to examine the relation between PFS scores and frequency of binge eating; and (3) to examine whether pre-treatment PFS scores predict weight change during treatment.
The PFS and measures of eating disorder symptomatology were administered to female patients with AN (N = 119) and BN (N = 144) at admission to residential treatment.
Participants with BN scored higher on the PFS compared to participants with AN-R or AN-B/P; there was a trend for those with AN-B/P to score higher than those with AN-R. PFS scores were positively associated with binge eating frequency among participants with BN; these associations remained significant when controlling for restraint and weight suppression. A similar pattern was found among participants with AN. PFS scores predicted weight change in AN but not BN.
Results suggest that hedonic processes may be important in stimulating binge eating. Furthermore, hedonic appetite may facilitate weight restoration in AN. Further research should investigate whether pre-treatment PFS scores have prognostic significance with respect to eating disorder symptoms.
享乐性饥饿，即一种在不存在能量不足的情况下为获得愉悦而进食的欲望，与暴饮暴食和对进食失去控制有关，但尚未在饮食失调患者中进行研究。
(1)比较神经性厌食症限制型（AN-R）、神经性贪食症暴食-清除型（AN-B/P）和神经性贪食症（BN）患者在享乐性饥饿自评量表（PFS）上的得分；(2)检验 PFS 得分与暴食发作频率之间的关系；(3)检验治疗前 PFS 得分是否能预测治疗期间的体重变化。
在住院治疗时，对女性 AN（N=119）和 BN（N=144）患者进行了 PFS 和饮食失调症状测量。
与 AN-R 或 AN-B/P 患者相比，BN 患者的 PFS 得分更高；与 AN-R 患者相比，AN-B/P 患者的得分有升高的趋势。在 BN 患者中，PFS 得分与暴食发作频率呈正相关；当控制了抑制和体重抑制后，这些关联仍然显著。在 AN 患者中也发现了类似的模式。PFS 得分预测了 AN 患者的体重变化，但对 BN 患者则没有。
结果表明，享乐性过程可能在刺激暴食方面很重要。此外，享乐性食欲可能有助于 AN 患者的体重恢复。进一步的研究应调查治疗前 PFS 得分是否对饮食失调症状具有预后意义。
