To investigate predictors of dropout from cognitive-behavior therapy for bulimia nervosa.
Pretreatment assessment measures were examined including the Eating Disorder Inventory-2, Body Satisfaction Questionnaire, Beck Depression Inventory, Beck Hopelessness Scale, the Locus of Control of Behavior Scale, and demographic and behavioral measures.
Forty-three percent (n = 14) of clients with a DSM-IV diagnosis of bulimia nervosa dropped out of treatment prematurely. No differences were found between treatment completers and dropouts with respect to the initial severity of bulimia-related symptoms. Noncompleters were, however, found to have significantly higher depression and hopelessness scores as well as elevated levels of external locus of control. Discriminate analysis showed that these variables resulted in a 90% prediction accuracy of individuals who prematurely dropped out of treatment.
Results suggest a need to focus treatment directly on factors such as hopelessness and depression in addition to standard bulimia procedures to ensure clients are able to engage in therapy.
调查神经性贪食症认知行为疗法治疗脱落的预测因素。
对治疗前评估指标进行了检查，包括饮食失调量表-2、身体满意度问卷、贝克抑郁量表、贝克绝望量表、行为控制源量表以及人口统计学和行为指标。
43%（n = 14）被诊断为神经性贪食症的DSM-IV患者过早退出治疗。在贪食相关症状的初始严重程度方面，治疗完成者和退出者之间未发现差异。然而，发现未完成治疗者的抑郁和绝望得分显著更高，且外部控制源水平升高。判别分析表明，这些变量对过早退出治疗的个体的预测准确率达到90%。
结果表明，除了标准的贪食症治疗程序外，还需要直接关注绝望和抑郁等因素，以确保患者能够参与治疗。
