Drug Therapy

47
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Area of Science:

  • Digital Health
  • Human-Computer Interaction
  • Health Informatics

Background:

  • Medication non-adherence is a significant healthcare issue, leading to adverse outcomes and increased costs.
  • Mobile health (mHealth) applications offer a potential solution to improve patient adherence.
  • Gamification strategies can enhance user engagement and adherence in mHealth interventions.

Purpose of the Study:

  • To present the development of MedScrab, a gamified mHealth app designed to improve medication adherence.
  • To evaluate the usability of MedScrab through a two-phase mixed-method approach.
  • To validate a modified mHealth App Usability Questionnaire (MAUQ) for assessing app usability.

Main Methods:

  • Phase I: Qualitative usability evaluation using a think-aloud protocol with 51 participants.
  • Phase I: Validation and reduction of the mHealth App Usability Questionnaire (MAUQ) from 18 to 15 items.
  • Phase II: Quantitative survey of 83 participants using the modified MAUQ on Amazon Mechanical Turk.

Main Results:

  • Qualitative analysis identified positive functionality and areas for improvement, which were incorporated into MedScrab's design.
  • The modified 15-item MAUQ demonstrated strong internal consistency (Cronbach's alpha = 0.959) and high factor loadings.
  • MedScrab was perceived as easy to use (6.24/7) and highly useful and satisfactory (5.72/7).

Conclusions:

  • MedScrab is a usable and satisfactory mHealth application for improving medication adherence.
  • The modified MAUQ is a valid instrument for measuring mHealth app usability, though adaptation may be needed.
  • The study provides a methodological guide for developing and evaluating mHealth interventions.
