Background:
Self-management programs can help patients with rheumatoid arthritis develop strategies to address their disease-related problems. However, accessibility to traditional self-management programs is often limited.
Purpose:
This study was developed to assess the effectiveness, feasibility, and acceptability of a smartphone-delivered self-management program application (app) for adults with rheumatoid arthritis.
Methods:
A two-arm (intervention vs. control) randomized controlled trial was used. Adult patients with rheumatoid arthritis were recruited from the rheumatology departments of a medical center. Study enrollment capabilities were limited by current pandemic restrictions. The patients who met the inclusion criteria and agreed to participate (N = 46) were enrolled as participants and randomly assigned either to the intervention group (n = 25), which received instructions on the use of a smartphone app designed to facilitate the self-management of rheumatoid arthritis, or to the control group (n = 21), which received instructions on related self-management only. The outcome variables were assessed at baseline and at 8 and 12 weeks. Differences in between-group outcomes over time were analyzed using generalized estimating equations. Feasibility and acceptability were also evaluated. Data were collected between August 1, 2020, and July 31, 2022.
Results:
At baseline, no differences were detected between the two groups in terms of the demographic and disease characteristics of concern. Outcome measures for the intervention group improved significantly more than the control group for self-efficacy of pain at 8 weeks (B = 6.39, p < .05) and for both of self-efficacy of pain and self-management behavior at 12 weeks (B = 9.16, p < .05, and B = 4.25, p < .001, respectively). Factors related to app ease of use included limiting pop-ups and windows and having no time restrictions. Most of the participants reported the app as acceptable and easy to use, although challenges relating to using technology limited the usability of the app for some.
Conclusions/Implications For Practice:
The smartphone app was shown to improve self-efficacy of pain and self-management behaviors. However, an accurate assessment of the effectiveness of the app and generalizability of the findings is limited by the smaller-than-desired sample size due to the COVID-19 pandemic and technological challenges. A greater understanding of how to overcome technological challenges is needed to optimize the delivery of self-management programs via smartphone-based apps. Studies reevaluating this app on a larger sample size should be conducted.
