Abstract

Objective

In the Diagnostic and Statistical Manual of Mental Disorders-5, severity of bulimia nervosa (BN) is defined by the frequency of purging behaviour. Previous research suggests the number of purging methods as an alternative rating. The current analysis investigated characteristics (sociodemographic and treatment-related variables, body mass index [BMI], eating disorder-specific and general psychopathology) of persons with BN as a function of purging frequency and number of purging methods in order to examine which approach might be better suited for indicating severity of BN.

Method

Two-hundred and sixty-one persons (98.5% female; mean age 25.2 years, SD = 9.41; mean BMI 22.0 kg/m², SD = 3.79) with BN completed self-report questionnaires on eating disorder-specific and general psychopathology at admission to inpatient (n = 214) or daypatient (n = 47) treatment.

Results

Higher severity based on either purging frequency or number of purging methods tended to relate to lower BMI and higher eating disorder-specific and general psychopathology. In addition, binge-eating frequency differentially related to eating disorder-specific and general psychopathology as a function of severity groups.

Conclusions

This study partially supports the utility of both purging frequency and the number of purging methods as indicators of severity in persons with BN. However, focussing only on purging behaviours may be short-sighted as it appears necessary to consider the number of binge-eating episodes as well when evaluating severity of BN.

作为贪食症严重程度指标的清食频率和清食方法数量：与暴食发作的交互影响。

目的在《精神疾病诊断与统计手册-5》中，神经性贪食症（BN）的严重程度是根据清食行为的频率来定义的。以往的研究建议将清食方法的次数作为替代评级。目前的分析调查了暴食症患者的特征（社会人口学和治疗相关变量、体重指数[BMI]、进食障碍特异性和一般精神病理学）与清食频率和清食方法次数的函数关系，以研究哪种方法可能更适合用于显示暴食症的严重程度：216名BN患者（98.5%为女性；平均年龄25.2岁，SD=9.41；平均体重指数（BMI）22.0 kg/m2，SD=3.79）在接受住院治疗（214人）或日间治疗（47人）时填写了有关饮食失调症特异性和一般精神病理学的自我报告问卷：根据清食频率或清食方法的数量得出的较高严重程度往往与较低的体重指数以及较高的饮食失调特异性和一般精神病理学有关。此外，暴饮暴食频率与进食障碍特异性和一般精神病理学的关系因严重程度组别而异：本研究部分支持将清食频率和清食方法的数量作为 BN 患者严重程度的指标。然而，只关注清食行为可能是短视的，因为在评估 BN 严重程度时，似乎也有必要考虑暴饮暴食发作的次数。
