To assess a new computer-based method of health education for patients with bulimia and anorexia nervosa.
Fifty-four patients with DSM-III-R diagnosed eating disorders were allocated randomly to one of two groups, one receiving a computer-presented health education package called DIET, the other experiencing a placebo computer-based program. Each group contained 14 anorexia nervosa patients, four anorexic patients with bulimia and nine bulimic patients. Groups were equivalent in terms of the severity of their eating disorder as measured on the Eating Disorders inventory and their estimated premorbid intelligence according to the National Adult Reading Test. Both groups were assessed before and after intervention on a questionnaire measuring knowledge of eating disorders and a questionnaire measuring attitudes to eating-disordered behaviour.
The DIET group members were significantly improved when compared to the placebo group in terms of both their knowledge and attitudes towards their disorder. The patients rated the DIET program as being both easy to use and helpful.
The DIET program has been found to be a resource-efficient means of health education for patients with eating disorders. Further research is required to assess whether the program has therapeutic effects in terms of behavioural improvement.
评估一种针对神经性贪食症和神经性厌食症患者的新型计算机辅助健康教育方法。
54名被DSM-III-R诊断为饮食失调的患者被随机分配到两组中的一组，一组接受名为DIET的计算机呈现的健康教育包，另一组体验基于计算机的安慰剂程序。每组包含14名神经性厌食症患者、4名神经性厌食合并贪食症患者和9名神经性贪食症患者。根据饮食失调问卷测量的饮食失调严重程度以及根据国家成人阅读测试估计的病前智力，两组相当。两组在干预前后均接受了一份测量饮食失调知识的问卷和一份测量对饮食失调行为态度的问卷评估。
与安慰剂组相比，DIET组成员在对自身疾病的知识和态度方面均有显著改善。患者对DIET程序的评价是易于使用且有帮助。
已发现DIET程序是一种对饮食失调患者资源高效的健康教育方式。需要进一步研究以评估该程序在行为改善方面是否具有治疗效果。
