The differences between adults and adolescents using a mobile health application for menstrual complaints: A usability and qualitative study.

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.

Instruments to Identify Menstrual Complaints and Their Impact on Adolescents: A Systematic Review.

STUDY OBJECTIVE: The aim of this review was to create an overview of available instruments used to evaluate the menstrual complaints of dysmenorrhea and heavy menstrual bleeding (HMB) in adolescents. METHODS: The search was conducted in PubMed, Web of Science, Embase, and PsycINFO on December 1, 2022. Studies published in English reporting on menstrual complaints among girls aged 10-19 were included. The quality and bias risk was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. RESULTS: Of 8994 identified studies, 57 were included. In these studies, 19 instruments were described, of which 8 were validated in adolescents. One was difficult to use in daily practice, 1 had low sensitivity and specificity in the detection of HMB, 2 were validated by face validity, and 2 were not specifically developed to evaluate (the impact of) menstrual complaints. Therefore, only 2 were validated and feasible to measure adolescent menstrual complaints: the Period ImPact and Pain Assessment (PIPPA) and the Adolescent Menstrual Bleeding Questionnaire (aMBQ). Remarkably, the Pictorial Blood Loss Assessment Chart (PBAC) was the most frequently used instrument in adolescents. There was one modified version of the PBAC for adolescents, which had a lower cutoff value for HMB and low sensitivity and specificity. CONCLUSION: We found that the PIPPA and aMBQ are suitable for assessing menstrual complaints and their impact on daily activities and health-related quality of life in adolescents. The PBAC, which is used frequently in adults, needs to be further assessed specifically for adolescents. In particular, the clinical relevance of the PBAC cutoff value for HMB should be determined for this age group. Considering the different interpretations, experiences, and limited knowledge of menstrual complaints, instruments suitable for adults may not be suitable for adolescents.
