However, about half of the patients with ED do not respond to treatments currently available, which call for efforts to expand the portfolio of treatments. The aim of this study was to explore experiences from patients who dropped out of a new treatment for bulimia nervosa and ...

      Background: Patient and public involvement (PPI) is increasingly considered an integral part of health research, and the focus has shifted from why we need PPI to how users can be involved in a meaningful way. The rationale for investigating experiences with PPI from the perspective of occupational therapy (OT)‐trained researchers' originates in the interrelationship between the inclusive approach ...

    • Patients'and therapists' experiences with a new treatment programme for eating disorders that combines physical exercise and dietary therapy: the PED-t trial. A qualitative study protocol. 

      Pettersen, Gunn; Rosenvinge, Jan H; Bakland, Maria; Wynn, Rolf; Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-08)
      Introduction:<br> Women with bulimia nervosa and binge eating disorder often suffer for many years before they seek professional help. Evidence-based treatments like cognitive–behavioural therapy (CBT) might be poorly accessible, and about 50% of those who receive CBT respond to it. Such outcome may reflect the heterogeneous nature of eating disorders, and addressing this heterogeneity calls ...

      Mathisen, Therese Fostervold; Rosenvinge, Jan H; Pettersen, Gunn; Friborg, Oddgeir; Vrabel, Kari-Anne; Bratland-Sanda, Solfrid; Svendsen, Mette; Stensrud, Trine; Bakland, Maria; Wynn, Rolf; Sundgot-Borgen, Jorunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-12)
      Background: <br> Sufferers from bulimia nervosa (BN) and binge eating disorder (BED) underestimate the severity risk of their illness and, therefore, postpone seeking professional help for years. Moreover, less than one in five actually seek professional help and only 50% respond to current treatments, such as cognitive behavioral therapy (CBT). The impetus for the present trial is to explore a ...

      <i>Background</i>: Individuals with intellectual disabilities (IDs) have lower levels of physical activity (PA) and greater barriers for participation in fitness activities compared with members of the general population. As increased PA has positive effects on cardiovascular and psychosocial health, it is exceedingly important to identify effective interventions for use in everyday settings. Mobile ...
    • The prestige of somatic and mental disporders : A suvey among health professionals and a representative general population sample 

      Rosenvinge, Jan H; Pettersen, Gunn; Olstad, Reidun E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
      Objective: The purpose of the paper is to study the ranking of disorders according to their perceived importance. Previous studies suggest that rankings according to the perceived or attributed “value” or importance create informal hierarchies of disorders on normative attitudes about symptoms, treatment and outcome. In this work we studied disorder ranking in the general population and among health ...
    • Profiles of Perfectionism Among Adolescents Attending Specialized Elite- and Ordinary Lower Secondary Schools: A Norwegian Cross-Sectional Comparative Study

      The versatile construct of perfectionism has been heavily debated, e.g., its nature or measurement constituents, how it influences performances or, most importantly, our health. Conventional linear analyses seem inadequate to address such challenges. Hence, we used a latent variable and a person-centered approach to identify different patterns of perfectionism, and their relationships with psychological ...

    • Psychopathy in women : theoretical and clinical perspectives 

      Wynn, Rolf; Høiseth, Marita; Pettersen, Gunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Prior research on psychopathy has primarily focused on the problem in men. Only a few studies have examined whether psychopathy even exists in women, and if so, how the disorder manifests itself in them. This paper presents a narrative review of the literature on gender and psychopathy. We briefly discuss why this is an important topic for women and we discuss its causes. The concept of psychopathy ...
    • Risk factors for sexual harassment and abuse victimization among adolescent athletes and non-athletes: A one-year follow-up study
