Show moreThe aim of this dissertation was to investigate whether and how E-health can help to improve health care for individuals with eating disorder symptoms. The main goal was to evaluate two E-health interventions: e-community ‘Proud2Bme’ and fully automated Internet-based intervention ‘Featback’. The effectiveness and cost-effectiveness of Featback with and without therapist support in comparison to a waiting was examined in a randomized controlled trial. Furthermore, potential moderators and mediators were investigated: what works for whom and what is the psychological mechanism that explains how Featback achieves its beneficial effects? Also, all online therapist communication within the Featback intervention was qualitatively examined. What did therapists actually do within the online support sessions as offered in addition to Featback? And can therapist behaviors predict participants’ outcome and satisfaction? Finally, this dissertation includes a systematic review of treating eating disorders over the Internet, as well a chapter about the emerging findings, issues, and opportunities regarding E-health for eating disorders in the past few years (2013-2015). How effective are Internet-based self-help interventions, -treatment, and -relapse prevention programs? What is the potential of Smartphone applications in treating eating disorders? What are the opportunities and challenges for the development and implementation of E-health for eating disorders? Show less

Show moreThe first aim of this study was to provide norms for the Eating Disorder Examination Questionnaire (EDE-Q) in a diverse and large clinical sample of individuals with an eating disorder (ED), and a general population sample without an ED. Norms for individuals with obesity without an ED were also provided, as a more relevant comparison group for individuals with binge eating disorder. The second aim was to investigate the discriminative validity of the EDE-Q. A sample of females with an ED (N=935), women from the general population without an ED (N=235), and obese females without an ED (N=321) completed the EDE-Q Explorative factor analyses did not support the theorized four subscales of the EDE-Q. Norms for EDE-Q global scores were provided for each of the three samples. Within the ED sample, norms were provided separately for patients with different ED diagnoses. Receiver operating characteristic analyses showed the EDE-Q global score to be highly accurate in discriminating individuals with an ED from those without, and moderately accurate in discriminating individuals with binge eating disorder from those with obesity. The presented norms contribute to a more accurate interpretation of EDE-Q scores, providing an index of the severity level of ED psychopathology. Furthermore, these norms can be used to assess clinical significant change during treatment. In addition, this study demonstrates that the EDE-Q when using its global score, is a valid instrument to assess levels of ED psychopathology. (C) 2012 Elsevier Ltd. All rights reserved. Show less
