Low ego strength is theoretically thought of as causing difficulties in interpersonal relations and leading to the development of psychiatric symptomatology. Patients with bulimia nervosa were previously shown to have low ego strength and were studied to investigate whether gains in ego strength occur over time and are associated with improvement in symptoms. The average patient had an ego strength at a borderline level at index and at a neurotic level 6 years later. Less positive change in ego strength was associated with a low initial Eating Disorder Inventory (EDI) Symptom score a long Time in Treatment, and having been referred for specialist care. Positive changers significantly more often stopped vomiting/abusing laxatives and showed several non-significant tendencies to improve in other symptomatic aspects as well. Several methodological caveats are discussed, but these findings may contribute to the identification of mechanisms whereby long-term improvement occurs in bulimia nervosa.
从理论上讲，自我力量薄弱被认为会导致人际关系方面的困难，并引发精神症状学的发展。先前的研究表明，神经性贪食症患者的自我力量较低，并对自我力量是否会随着时间的推移而增强以及是否与症状改善相关进行了研究。平均而言，患者在初始时自我力量处于临界水平，6年后处于神经质水平。自我力量较少的积极变化与较低的初始饮食失调量表（EDI）症状评分、较长的治疗时间以及被转诊至专科护理有关。积极变化者更常停止呕吐/滥用泻药，并且在其他症状方面也有一些虽不显著但趋于改善的倾向。文中讨论了几个方法上的注意事项，但这些发现可能有助于确定神经性贪食症长期改善所涉及的机制。
