The authors examined the temporal stability and predictive utility of bulimic symptoms and related variables over the course of 10 years, from 1982 to 1992.
The subjects were 459 women who were aged 18-22 years in 1982 and were surveyed in both 1982 and 1992. Each respondent completed five subscales of the Eating Disorders Inventory (bulimia, drive for thinness, maturity fears, perfectionism, and interpersonal distrust) and answered questions based on the DSM-III criteria for bulimia nervosa.
The temporal stability of bulimic symptoms and related variables was relatively high. Bulimic status in 1982 conferred an approximately 15-fold increase in risk 10 years later. Drive for thinness and, to lesser degrees, maturity fears and perfectionism received support as long-term predictors of bulimic symptoms.
Bulimic symptoms display high temporal stability and thus may affect long-term functioning and well-being. Later symptoms are related to scores on specific subscales of the Eating Disorders Inventory administered 10 years earlier. Assessment and therapy should be conducted accordingly.
作者研究了1982年至1992年这10年间贪食症状及相关变量的时间稳定性和预测效用。
研究对象为459名女性，她们在1982年年龄为18 - 22岁，并在1982年和1992年都接受了调查。每位受访者完成了饮食失调量表的五个分量表（贪食、对瘦身的追求、对成熟的恐惧、完美主义和人际不信任），并根据精神疾病诊断与统计手册第三版中神经性贪食症的标准回答问题。
贪食症状及相关变量的时间稳定性相对较高。1982年的贪食状态使10年后患病风险增加了约15倍。对瘦身的追求以及程度较轻的对成熟的恐惧和完美主义，被证实是贪食症状的长期预测因素。
贪食症状表现出较高的时间稳定性，因此可能会影响长期的功能和幸福感。后期症状与10年前所做饮食失调量表特定分量表的得分相关。评估和治疗应据此进行。
