Disturbance in the way the body is experienced is a diagnostic criterion for anorexia nervosa, and impedes recovery. A method relatively free of external prompts, to reduce the potential for experimentally induced biases, evaluated body image distortions (BID) in 18 patients with anorexia nervosa soon after admission to an inpatient unit, and 18 normal controls, before and after a videofeedback session. The BID were assessed in the affective and self/social domains by visual analogue scales in which the instructional set oriented subjects to (a) the sensation of fatness (Affective Response, AR), and (b) size compared with other young women (Comparative Size Response, CSR). The AR and CSR were significantly greater than normal in anorexia but decreased significantly with videofeedback, while values for controls were stable. The AR and CSR were only partially independent, indicating overlap of the domains. In anorexia only, the responses were related to two DSM-IV diagnostic criteria for anorexia, fear of gaining weight and health-weight concerns, as well as to drive for thinness and body dissatisfaction. Fear of gaining weight occupied a central position in determining the magnitudes of BID and the other measures, including anxiety and depression.
身体体验方式的紊乱是神经性厌食症的一项诊断标准,且会妨碍康复。一种相对不受外部提示影响、以减少实验性诱导偏差可能性的方法,在18名神经性厌食症患者入院后不久以及18名正常对照者接受视频反馈治疗前后,对身体形象扭曲(BID)进行了评估。通过视觉模拟量表在情感和自我/社会领域评估BID,其中指导语使受试者关注(a)肥胖感(情感反应,AR),以及(b)与其他年轻女性相比的体型(比较体型反应,CSR)。神经性厌食症患者的AR和CSR显著高于正常水平,但在视频反馈后显著降低,而对照组的值则保持稳定。AR和CSR仅部分独立,表明这些领域存在重叠。仅在神经性厌食症中,这些反应与神经性厌食症的两项《精神疾病诊断与统计手册》第四版(DSM-IV)诊断标准相关,即对体重增加的恐惧和对健康体重的担忧,以及对消瘦的追求和对身体的不满。对体重增加的恐惧在确定BID的程度以及包括焦虑和抑郁在内的其他指标方面占据核心地位。
