Usability of the "Systematic Review Support" computer system: a methodological study.

BACKGROUND

(1) The "Systematic Review Support" system has a high degree of perceived usability.

BACKGROUND

(2)  Its use facilitates the exclusion of duplicate references and the selection of studies.

BACKGROUND

(3)  Remote and synchronous usability testing made research possible during the pandemic.

BACKGROUND

(4)  Combining usability techniques made it possible to identify the necessary adjustments.

BACKGROUND

(5)  The method used expanded the test's capacity in a real context of use.

to evaluate the usability of the "Systematic Review Support" computer system.

methodological study involving 21 students who evaluated the computer system in a remote and synchronous usability test. Two activities were carried out, containing 21 tasks simulating the initial steps of a review study, proposals for eliminating duplicate references, selecting studies and resolving disagreements between evaluators. At the end, participants answered the System Usability Scale questionnaire. The measures used were: completion rate with assistance (effectiveness) and time to complete the task (efficiency). The data was described in a table using the mean, standard deviation, minimum and maximum values.

in a total of 21 tasks, the participants had an assisted completion rate of 9% and an average time of 55.1 minutes (the expected time being 60 minutes). The average score provided by the System Usability Scale instrument was 82.4 (considering a score from 0 to 100), median 85; minimum value 35 and maximum 97.5.

the computer system has the effectiveness and efficiency parameters required of a computer review tool. It has a usability score of 82.4 on a scale of 0 to 100 assessed by the System Usability Scale instrument. The version presented incorporates the adjustments identified in the test in use.
