Aim:
To provide a technical basis and evaluate usability and associated factors of Brain Health Promotion mHealth App.
Methods:
Adults with Subjective Memory Complaints (SMC) and Mild Cognitive Impairment (MCI) participated in the study. Usability differences between them were assessed using a t-test, while regression analysis examined associated factors. Two-step clusters identified the multiple features of users matching the usability.
Results:
The App's usability in adults with SMC and MCI were 43.45 ± 4.57 and 39.75 ± 3.06 (t = 4.356, p < 0.001). Usability was associated with objective cognition, e-Health literacy, and age, while education level emerged as the strongest predictor among four clusters of heterogeneous usability.
Conclusion:
Adults with SMC gave a high usability evaluation for the App and affirmed its value in brain health promotion. The intervention was feasible. However, multi-dimensional factors should be considered to realize efficient usability and multilevel optimization of the App.
