Methodological Quality of Manuscripts Reporting on the Usability of Mobile Applications for Pain Assessment and Management: A Systematic Review.

BACKGROUND

There has been increasing use of mobile mHealth applications, including pain assessment and pain self-management apps. The usability of mHealth applications has vital importance as it affects the quality of apps. Thus, usability assessment with methodological rigor is essential to minimize errors and undesirable consequences, as well as to increase user acceptance.

OBJECTIVE

this study aimed to synthesize and evaluate existing studies on the assessment of the usability of pain-related apps using a newly developed scale.

METHODS

an electronic search was conducted in several databases, combining relevant keywords. Then titles and abstracts were screened against inclusion and exclusion criteria. The eligible studies were retrieved and independently screened for inclusion by two authors. Disagreements were resolved by discussion until consensus was reached.

RESULTS

a total of 31 articles were eligible for inclusion. Quality assessment revealed that most manuscripts did not assess usability using valid instruments or triangulation of methods of usability assessment. Most manuscripts also failed to assess the three domains of usability (effectiveness, efficiency and satisfaction).

CONCLUSIONS

future studies should consider existing guidelines on usability assessment design, development and assessment of pain-related apps.
