Binge eating, a major public health problem, is characterized by recurrent episodes of out-of-control eating in which an individual consumes an unusually large amount of food in a discrete time period. Limitations of existing treatments for binge eating (both in-person psychotherapy and guided self-help) indicate that smartphone applications (apps) may be an ideal alternative or enhancement. An app for binge eating could aid treatment dissemination, engagement, and/or compliance. However, no research to date has examined user perceptions of a therapeutic app for binge eating, which is critical for development. ⋯ The current study details highly specific feedback and ideas regarding essential app features from target users and clinicians. This information is critical for the development of future apps to treat binge eating. Ways in which data obtained from the current study may be generalized to the development of therapeutic apps for other psychological disorders is discussed.

Evidence in favor of mHealth for healthcare delivery in settings where trained health workforce is limited or unavailable is accumulating. With rapid growth in access to mobile phones and an acute shortage of health workforce in Bangladesh, mHealth initiatives are increasing with more than 20 current initiatives in place. "Readiness" is a crucial prerequisite to the successful implementation of telehealth programs. However, systematic assessment of the community readiness for mHealth-based services in the country is lacking. We report on a recent study describing the influence of community readiness for mHealth of a rural Bangladesh community. ⋯ We developed a conceptual framework to assess community readiness for mHealth. We described three high level dimensions of readiness and have partially tested the conceptual framework in a rural sub-district in Bangladesh. We found that the community has some technological readiness but inequity was observed for human resource readiness and technological capabilities. The study population is motivated to use mHealth. Our conceptual framework is a promising tool to assist policy-makers in planning and implementing mHealth programs.

This article reports the user-oriented evaluation of a text- and content-based medical image retrieval system. User tests with radiologists using a search system for images in the medical literature are presented. The goal of the tests is to assess the usability of the system, identify system and interface aspects that need improvement and useful additions. Another objective is to investigate the system's added value to radiology information retrieval. The study provides an insight into required specifications and potential shortcomings of medical image retrieval systems through a concrete methodology for conducting user tests. ⋯ The iterative character of the evaluation helped to obtain diverse and detailed feedback on all system aspects. Radiologists are quickly familiar with the functionalities but have several comments on desired functionalities. The analysis of the results can potentially assist system refinement for future medical information retrieval systems. Moreover, the methodology presented as well as the discussion on the limitations and challenges of such studies can be useful for user-oriented medical image retrieval evaluation, as user-oriented evaluation of interactive system is still only rarely performed. Such interactive evaluations can be limited in effort if done iteratively and can give many insights for developing better systems.
