Insights
Health apps for chronic arthritis (CA) patients often lack social and dialogue support features. Enhancing these, along with system credibility and task support, can improve patient adherence and disease management.
Area of Science:
- Digital health interventions for chronic disease management.
- Application of persuasive technology in healthcare.
Background:
- Chronic arthritis (CA) affects a significant population, necessitating long-term patient adherence to medication and exercise programs.
- Low adherence rates highlight the need for supportive tools, leading to the development of health apps for CA self-management.
- Persuasive principles in health apps aim to motivate users towards target behaviors, but their application in CA apps is not well understood.
Purpose of the Study:
- To systematically evaluate the presence and types of persuasive principles integrated into existing health applications designed for chronic arthritis patients.
Main Methods:
- A comprehensive review of 28 arthritis-focused mobile applications was conducted across major app stores (Google Play, Apple App Store, Windows Phone Store).
- Apps were analyzed and coded based on 37 persuasive principles derived from established taxonomies (Persuasive System Design and Behavior Change Techniques).
- Additional data collected included user ratings, download counts, and app pricing.
Main Results:
- The analyzed apps incorporated an average of 5.8 out of 37 persuasive principles.
- System Credibility (2.6 principles) and Task Support (2.3 principles) were the most frequently utilized categories.
- Dialogue Support (0.5 principles) and Social Support (0.01 principles) were significantly underrepresented.
Conclusions:
- Current health apps for chronic arthritis patients could be improved by incorporating more social support features (e.g., forums, social media integration) and dialogue support techniques (e.g., rewards, praise).
- Enhanced task support through automated health parameter tracking (e.g., physical activity) can further ease disease management for patients.
- A stronger evidence-based approach in app development and content verification is recommended to bolster system credibility and ensure scientific validity.
Background:
Chronic arthritis (CA), an umbrella term for inflammatory rheumatic and other musculoskeletal diseases, is highly prevalent. Effective disease-modifying antirheumatic drugs for CA are available, with the exception of osteoarthritis, but require a long-term commitment of patients to comply with the medication regimen and management program as well as a tight follow-up by the treating physician and health professionals. Additionally, patients are advised to participate in physical exercise programs. Adherence to exercises and physical activity programs is often very low. Patients would benefit from support to increase medication compliance as well as compliance to the physical exercise programs. To address these shortcomings, health apps for CA patients have been created. These mobile apps assist patients in self-management of overall health measures, health prevention, and disease management. By including persuasive principles designed to reinforce, change, or shape attitudes or behaviors, health apps can transform into support tools that motivate and stimulate users to achieve or keep up with target behavior, also called persuasive systems. However, the extent to which health apps for CA patients consciously and successfully employ such persuasive principles remains unknown.
Objective:
The objective of this study was to evaluate the number and type of persuasive principles present in current health apps for CA patients.
Methods:
A review of apps for arthritis patients was conducted across the three major app stores (Google Play, Apple App Store, and Windows Phone Store). Collected apps were coded according to 37 persuasive principles, based on an altered version of the Persuasive System Design taxonomy of Oinas-Kukkonen and Harjuma and the taxonomy of Behavior Change Techniques of Michie and Abraham. In addition, user ratings, number of installs, and price of the apps were also coded.
Results:
We coded 28 apps. On average, 5.8 out of 37 persuasive principles were used in each app. The most used category of persuasive principles was System Credibility with an average of 2.6 principles. Task Support was the second most used, with an average of 2.3 persuasive principles. Next was Dialogue Support with an average of 0.5 principles. Social Support was last with an average of 0.01 persuasive principles only.
Conclusions:
Current health apps for CA patients would benefit from adding Social Support techniques (eg, social media, user fora) and extending Dialogue Support techniques (eg, rewards, praise). The addition of automated tracking of health-related parameters (eg, physical activity, step count) could further reduce the effort for CA patients to manage their disease and thus increase Task Support. Finally, apps for health could benefit from a more evidence-based approach, both in developing the app as well as ensuring that content can be verified as scientifically proven, which will result in enhanced System Credibility.
