Technology assisted guided self-help has been proven to be effective in the treatment of bulimia nervosa (BN). The aim of this study was to determine predictors of good long-term outcome as well as drop-out, in order to identify patients for whom these interventions are most suitable.
One hundred and fifty six patients with BN were assigned to either 7 months internet-based guided self-help (INT-GSH) or to conventional guided bibliotherapy (BIB-GSH), both guided by e-mail support. Evaluations were taken at baseline, after 4, 7, and 18 months. As potential predictors, psychiatric comorbidity, personality features, and eating disorder psychopathology were considered.
Higher motivation, lower frequency of binge eating, and lower body dissatisfaction at baseline predicted good outcome after the end of treatment. Lower frequency of binge eating predicted good outcome at long-term follow-up. Factors prediciting drop-out were higher depression and lower self-directedness at baseline.
Technology assisted self-help can be recommended for patients with a high motivation to change, lower binge-eating frequency and lower depression scores.
技术辅助的自助指导已被证明对神经性贪食症（BN）的治疗有效。本研究旨在确定良好的长期预后和脱落的预测因素，以便确定哪些患者最适合这些干预措施。
156 名 BN 患者被分配到 7 个月的基于互联网的自助指导（INT-GSH）或传统的自助指导阅读疗法（BIB-GSH），两者均通过电子邮件支持进行指导。在基线、4 个月、7 个月和 18 个月时进行评估。作为潜在的预测因素，考虑了精神共病、人格特征和饮食障碍心理病理学。
较高的动机、较低的暴食频率和较低的身体不满在治疗结束后预测良好的治疗效果。较低的暴食频率预测了长期随访的良好结果。预测脱落的因素是基线时较高的抑郁和较低的自我导向。
技术辅助的自助指导可以推荐给那些有强烈改变动机、较低暴食频率和较低抑郁评分的患者。
