A number of theories have been proposed to explain the substantial comorbidity between the eating disorders and the substance-related disorders. Among them is the claim that self-starvation--exacerbated by excessive exercising--is itself an addiction to the body's endogenous opioids. While efforts have also been made to identify an "addictive personality," attempts to establish whether eating-disordered patients share these characteristics have met with mixed success. The present study was designed to determine the degree to which anorexic and bulimic patients display addictive personality characteristics, and whether these traits are useful in predicting the severity of the patient's weight preoccupation and their degree of excessive exercising. Results confirmed that both anorexic and bulimic patients had high scores on the Addiction Scale of the Eysenck Personality Questionnaire, and that addictiveness and obsessive-compulsiveness were related simultaneously to weight preoccupation and excessive exercising in both patient groups. Findings are discussed within the framework of the auto-addiction opioid theory, and they highlight the similarities and differences in the personality structure of the eating-disorder subtypes.
已经提出了许多理论来解释饮食失调症和物质相关障碍之间的大量共病现象。其中一种观点认为，自我饥饿（因过度运动而加剧）本身就是对身体内源性阿片类物质的成瘾。虽然也有人努力去识别“成瘾人格”，但试图确定饮食失调患者是否具有这些特征的尝试结果喜忧参半。本研究旨在确定厌食症和贪食症患者表现出成瘾人格特征的程度，以及这些特征是否有助于预测患者对体重的过度关注程度和过度运动的程度。结果证实，厌食症和贪食症患者在艾森克人格问卷成瘾量表上得分都很高，并且成瘾性和强迫性在两组患者中都与对体重的过度关注和过度运动同时相关。研究结果在自我成瘾阿片类理论的框架内进行了讨论，突出了饮食失调亚型人格结构的异同。
