This article examines the continuity/discontinuity perspective of eating pathology among 375 women seeking treatment.
Participants were categorized into five separate groups: obese nonbingers, subthreshold binge eating disorder (BED), BED, subthreshold bulimics, and bulimics. We tested whether differences in core eating pathology (drive for thinness, body dissatisfaction, current body image, body image ideal) and psychiatric symptoms (depression, interoceptive awareness) differentiated the groups quantitatively (supporting the continuity perspective) or qualitatively (supporting the discontinuity perspective).
Our results, overall, supported the continuity perspective of eating pathology. A discriminant function analysis using the eating pathology and psychiatric symptom variables as predictor variables found that one primary factor differentiated the five groups on both core eating pathology and psychiatric variables.
The implications of testing this model within a treatment-seeking sample are discussed.
本文探讨了375名寻求治疗的女性饮食病理学的连续性/非连续性观点。
参与者被分为五个独立的组：肥胖非暴食者、阈下暴食障碍（BED）、BED、阈下贪食症患者和贪食症患者。我们测试了核心饮食病理学（对瘦的追求、身体不满、当前身体形象、理想身体形象）和精神症状（抑郁、内感受性觉知）的差异是在数量上区分这些组（支持连续性观点）还是在质量上区分（支持非连续性观点）。
总体而言，我们的结果支持饮食病理学的连续性观点。使用饮食病理学和精神症状变量作为预测变量的判别函数分析发现，一个主要因素在核心饮食病理学和精神变量上区分了这五个组。
讨论了在寻求治疗的样本中测试该模型的意义。
