Background:
A "Menstruatie Educatie Kalender" application (Menstruation Education Calendar, (MEK-APP)) was developed for adults to evaluate menstrual complaints. The future aim of this app is to use it as a self-diagnostic instrument for menstrual abnormalities for both adults and adolescents. Early identification of the potential of an application for future use by both user groups would increase implementation success and adoption of the application.
Objective:
To compare differences in experienced usability by adults versus adolescents and to identify factors influencing future use for both age groups in one mHealth application (in this study the MEK-APP).
Methods:
This study consisted of three phases: (1) usability testing of the MEK-APP for iOS and Android by think-aloud method, (2) two-month daily use and (3) in-depth individual interview. During the think-aloud sessions, twelve tasks were performed in the application while they were thinking aloud. Usability problems were rated for their severity with Nielsen' Severity Scale. Both the think-aloud sessions and in-depth interviews were verbatim transcribed and thematically analyzed to determine the factors influencing future use for both groups. In addition, the System Usability Scale (SUS) and Intrinsic Motivation Inventory (IMI) questionnaires were filled out during the interviews.
Results:
Seven adults (>18 years) and seven adolescents (14-18 years) evaluated the MEK-APP. There were 14 usability issues and 16 bugs in both groups. There were no differences between adults and adolescents. In the thematic qualitative analysis, the following future use factors were identified: user-expectation, motivation, privacy, understandability, and user-experience. The user-expectation, motivation and privacy differed between both groups but did not influence usage. No differences were observed in SUS and IMI scores between both groups.
Conclusions:
There are five factors influencing the future use of a menstrual-related mHealth application for both adults and adolescents. It is possible to serve different age groups with a single application.
