The Use of General Health Apps Among Users with Specific Conditions: Why College Women with Disordered Eating Adopt Food Diary Apps.

There is a myriad of mobile health applications designed to address a variety of health conditions. While these apps hold significant promise for the management of these conditions, users sometimes turn to general health apps, rather than those designed with their specific condition in mind, which can lead to unmet needs and worsened conditions. We outline one example by focusing on college women with disordered eating behaviors and their use of general food diary apps, rather than eating disorder-specific apps. We investigate the types of health apps they use and how they choose them, focusing on the role of motivations and search behavior. We found their initial motivation informs their search process, which results in their selection of general food diary apps. Researchers should consider app adoption as influenced by user motivations and navigation behavior, particularly when determining how and why general apps are used and how clinicians can help.
