The investigators plan to collect preliminary data on the feasibility, acceptability, and user uptake of a personalized self-guided mobile intervention for disordered eating (DE) and test the initial clinical efficacy of this intervention. Women (N=50) who endorse significant DE will complete two weeks of smart-phone self-monitoring to identify target problems and will be sent two self-guided modules of personalized treatment directly to their smart-phones. The investigators will assess engagement with the modules throughout two months and administer baseline, week 5, and week 8 assessments for acceptability, uptake, and initial clinical efficacy (e.g., DE symptoms, anxiety, quality of life). The investigators will also complete a focus group (n=10) with a subset of users to receive input on the mobile-application assessment and ease of self-guided intervention modules.
