[Extract] Eating disorders (EDs) in the community are associated with high burden and poor quality of life (Mathers et al., 2000, Hay & Mond, 2005). It is also known that people with EDs have frequent chronic medical complications (Mehler, 2003), increased risk of obesity especially for the more common bulimic EDs such as binge eating disorder (Neumark-Sztainer et al., 2006; Hudson et al., 2007)) and high levels of co-morbidity with both depression and anxiety (Hudson et al., 2007). However, there is a wide gap between the presence of a disorder and its identification and treatment. It is well-documented that the overwhelming majority of people in the community with an ED do not seek help for their eating behaviours (Hart et al., in press; Welch & Fairburn 1994), and that even fewer access appropriate or evidencebased treatments (Cachelin & Striegel-Moore,2006; Mond et al., 2009). This is problematic as many randomised controlled trials support the efficacy of treatments, such as cognitivebehaviour therapy for bulimic EDs (Hay et al., 2004) and unmet treatment needs likely add to the general community burden from psychiatric disorders (Andrews et al., 2000). In addition, these disorders often become chronic with longitudinal studies indicating persistence of symptoms over many years (Fairburn et al., 2000, Evans et al., 2011).
