Data collectors collect health data using Mobile Electronic Data Collection Forms (MEDCFs) particularly in hard to reach areas. However, the usability and user acceptance of these forms by the data collectors are seldom considered, and yet these have an implication on the quality of the data collected and on the health decisions thereof. In this study we aimed at collecting the design preferences the data collectors felt would improve their data collection experience. For that purpose, a mid-fidelity prototype was used to accomplish six tasks and a semi-structured usability questionnaire was given. Forty eight data collectors from Uganda participated in the study between December 2017 and January 2018, indicating their preferences after interacting with the prototype. The results included a detailed feedback regarding the presentation of the forms content, form navigation, error handling, data input, and visualization of progress status. Involvement of users and other stakeholders in the design of MEDCFs using the User Centred Design (UCD) will presumably enhance usability of the data collection forms.
