Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Background:

Medication nonadherence is a major issue in chronic disease management, increasing costs and reducing treatment effectiveness.
Innovative digital interventions are needed to address factors contributing to nonadherence.
Gamified mobile applications show potential for behavior change and patient engagement.

Purpose of the Study:

To evaluate the efficacy and usability of a gamified mobile app with a narrative approach for enhancing medication adherence in acute coronary syndrome (ACS) patients.
To assess changes in patients' beliefs about medication and self-reported adherence post-intervention.
To gather user feedback on the app's narrative component.

Main Methods:

A 1-month pilot study involving 18 patients with recent ACS.
Pre- and post-intervention assessments of medication beliefs and self-reported adherence using standardized scales.
Post-intervention usability evaluation via questionnaire and analysis of user feedback.

Main Results:

12 out of 18 participants remained engaged for the full 30 days.
Self-reported medication adherence significantly improved (P<.05) post-intervention.
Participants reported increased self-efficacy regarding their medication regimen, though beliefs about medication did not significantly change.
The app achieved a good usability rating (mean score 80.6), but the narrative element was not well-received.

Conclusions:

A gamified mobile app shows promise in improving medication adherence and self-efficacy in ACS patients.
The narrative component of the app requires refinement to enhance user engagement.
Future research should explore alternative engagement strategies within digital health interventions for medication adherence.
