Repetitive body checking and avoidance are viewed as behavioral manifestations of the core psychopathology of eating disorders (EDs). We examined select body checking and avoidance behaviors in overweight patients with binge eating disorder (BED).
Three hundred seventy-seven overweight (body mass index [BMI] > or = 25) treatment-seeking BED patients (80 men and 297 women) were administered measures to assess body checking and avoidance, other key behavioral features of EDs (binge eating, dietary restraint, and disinhibition), and the core psychopathology of EDs (overevaluation of weight and shape).
The majority of participants reported regularly pinching areas of their body to check for fatness and avoided wearing clothing that made them particularly aware of their body. Significant associations emerged between checking and restraint, and conversely, between avoidance and binge eating. Both checking and avoidance were positively and significantly associated with overevaluation of weight and shape, even after controlling for their unique effects.
These findings offer support to the potential role of checking and avoidance behaviors in the maintenance of BED.
反复进行身体检查和回避行为被视为饮食失调（EDs）核心精神病理学的行为表现。我们研究了患有暴食症（BED）的超重患者的特定身体检查和回避行为。
对377名寻求治疗的超重（体重指数[BMI]≥25）BED患者（80名男性和297名女性）进行测量，以评估身体检查和回避行为、饮食失调的其他关键行为特征（暴饮暴食、饮食限制和去抑制）以及饮食失调的核心精神病理学（对体重和体型的过度评价）。
大多数参与者报告定期捏身体部位以检查是否肥胖，并避免穿会让他们特别注意自己身材的衣服。检查与限制之间存在显著关联，相反，回避与暴饮暴食之间也存在显著关联。即使在控制了它们的独特影响之后，检查和回避行为与对体重和体型的过度评价均呈显著正相关。
这些发现支持了检查和回避行为在维持BED方面的潜在作用。
