BACKGROUND
Bulimic eating disorders are common among female students, yet the majority do not access effective treatment. Internet-based cognitive-behavioural therapy (iCBT) may be able to bridge this gap.
METHOD
Seventy-six students with bulimia nervosa (BN) or eating disorder not otherwise specified (EDNOS) were randomly assigned to immediate iCBT with e-mail support over 3 months or to a 3-month waiting list followed by iCBT [waiting list/delayed treatment control (WL/DTC)]. ED outcomes were assessed with the Eating Disorder Examination (EDE) at baseline, 3 months and 6 months. Other outcomes included depression, anxiety and quality of life.
RESULTS
Students who had immediate iCBT showed significantly greater improvements at 3 and 6 months than those receiving WL/DTC in ED and other symptoms.
CONCLUSIONS
iCBT with e-mail support is efficacious in students with bulimic disorders and has lasting effects.
背景
贪食症是女学生中常见的饮食障碍，但大多数人无法获得有效的治疗。基于互联网的认知行为疗法（iCBT）或许可以弥补这一差距。
方法
76 名神经性贪食症或未特定的饮食障碍患者被随机分配至立即接受为期 3 个月的 iCBT 加电子邮件支持，或先进入 3 个月的候补名单，再接受 iCBT[候补名单/延迟治疗对照（WL/DTC）]。在基线、3 个月和 6 个月时使用饮食障碍检查（EDE）评估 ED 结果。其他结果包括抑郁、焦虑和生活质量。
结果
与接受 WL/DTC 的患者相比，立即接受 iCBT 的患者在 3 个月和 6 个月时 ED 及其他症状的改善更为显著。
结论
带电子邮件支持的 iCBT 对贪食障碍患者有效，且具有持久效果。
