A Review of Usability Evaluation Methods and Their Use for Testing eHealth HIV Interventions.

Purpose of review: To provide a comprehensive review of usability testing of eHealth interventions for HIV. Recent findings: We identified 28 articles that assessed the usability of eHealth interventions for HIV, most of which were published within the past 3 years. The majority of the eHealth interventions for HIV was developed on a mobile platform and focused on HIV prevention as the intended health outcome. Usability evaluation methods included eye-tracking, questionnaires, semi-structured interviews, contextual interviews, think-aloud protocols, cognitive walkthroughs, heuristic evaluations and expert reviews, focus groups, and scenarios. A wide variety of methods is available to evaluate the usability of eHealth interventions. Employing multiple methods may provide a more comprehensive assessment of the usability of eHealth interventions as compared with inclusion of only a single evaluation method.
