ABSTRACT 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.
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.
Students who had immediate iCBT showed significantly greater improvements at 3 and 6 months than those receiving WL/DTC in ED and other symptoms.
iCBT with e-mail support is efficacious in students with bulimic disorders and has lasting effects.

    ABSTRACT: The widespread availability of the Internet and mobile-device applications (apps) is changing the treatment of mental health problems. The aim of the present study was to review the research on the effectiveness of e-therapy for eating disorders, using the methodology employed by the UK’s National Institute for Health and Care Excellence (NICE). Electronic databases were searched for published randomised controlled trials of e-therapies, designed to prevent or treat any eating disorder in all age groups. Studies were meta-analysed where possible, and effect sizes with confidence intervals were calculated. The GRADE approach was used to determine the confidence in the effect estimates. Twenty trials met the inclusion criteria. For prevention, a CBT-based e-intervention was associated with small reductions in eating disorder psychopathology, weight concern and drive for thinness, with moderate confidence in the effect estimates. For treatment and relapse prevention, various e-therapies showed some beneficial effects, but for most outcomes, evidence came from single studies and confidence in the effect estimates was low. Overall, although some positive findings were identified, the value of e-therapy for eating disorders must be viewed as uncertain. Further research, with improved methods, is needed to establish the effectiveness of e-therapy for people with eating disorders.

    ABSTRACT: Abstract Background: Despite effective treatment approaches, relapses are frequent in eating disorders. Posttreatment care is essential to enhance continuous recovery and prevent deterioration. This study evaluated the effects of an Internet-based intervention following routine care. Materials and Methods: One hundred five women who received treatment for bulimia nervosa and related eating disorders not otherwise specified were randomly assigned either to an immediate Internet-based support program (EDINA) over 4 months or to a 4-month waiting-list treatment as usual (TAU) control condition. The primary outcome was eating disorder-related attitudes at baseline and after 4 months assessed by the Eating Disorder Examination Questionnaire (EDE-Q). Results: The program proved feasible and was well accepted. A significant reduction in eating disorder-related attitudes could be shown for both groups at the end of the 4 months. There was a tendency for participants of the aftercare intervention to show better results on all outcome measures. In total, 40.6% (13/32) of the EDINA participants and 24.4% (10/41) of the TAU participants showed statistically reliable improvement on the EDE-Q total score by the end of the intervention period [χ(2)(1)=2.195, p=0.138]. Conclusions: The Internet-based support program was feasible and well accepted but did not prove efficacious in a heterogeneous sample of patients following routine care.

    ABSTRACT: Depressive and eating disorder symptoms are highly comorbid. To date, however, little is known regarding the efficacy of existing programs in decreasing concurrent eating disorder and depressive symptoms. We conducted a systematic review of selective and indicated controlled prevention and early intervention programs that assessed both eating disorder and depressive symptoms. We identified a total of 26 studies. The large majority of identified interventions (92%) were successful in decreasing eating disorder symptoms. However fewer than half (42%) were successful in decreasing both eating disorder and depressive symptoms. Intervention and participant characteristics did not predict success in decreasing depressive symptoms. Indicated prevention and early intervention programs targeting eating disorder symptoms are limited in their success in decreasing concurrent depressive symptoms. Further efforts to develop more efficient interventions that are successful in decreasing both eating disorder and depressive symptoms are warranted.
