The latter activity is, however, counterproductive, as it entrenches pro-anorexia users in their stance. Conclusions: Our results highlight the nature of pro-anorexia and pro-recovery photo sharing and accentuate the need for clinicians to be aware of such content and its effect on their patients. Our findings suggest that some currently used interventions are not useful in helping pro-anorexia users recover. Thus, future work should focus on new intervention methods, possibly tailored to individual characteristics. %M 23134671 %R 10.2196/jmir.2239 %U //www.mybigtv.com/2012/6/e151/ %U https://doi.org/10.2196/jmir.2239 %U http://www.ncbi.nlm.nih.gov/pubmed/23134671
