Effects of a web-based intervention for adults with chronic conditions on patient activation: Online randomized controlled trial

Original research paper


Background:  With almost one-half of Americans projected to have at least one chronic condition before 2020, a vital role of the health care system is to develop informed, engaged individuals who are effective self-managers of their health.  Self-management interventions delivered by face-to-face or telephonic modalities (traditional SMIs) are associated with improvements in self-management knowledge, skills, and self-efficacy – which are expressed by the composite construct of patient activation – a predictor of health outcomes. Web-based interventions to support self-management across the spectrum of different types of chronic diseases have the potential to reach a broader population of patients for extended periods compared to traditional SMIs. However, evidence of the effectiveness of web-based interventions on patient activation is sparse. High quality studies featuring controlled comparisons of patients with different chronic conditions are needed to explore the interaction of web-based interventions and patient activation.  

Objective:  To explore the effect of a web-based intervention on the patient activation levels of patients with chronic health conditions.

Methods:  For this 12-week study, prospective participants were selected from the patient panel of a regional health care system located in the United States. The 201 eligible participants were randomly assigned to two groups. Intervention group participants had access to MyHealth Online (MHO), a patient portal featuring interactive health applications accessible via the Internet. Control participants had access to a health education website featuring various topics. Patient activation was assessed pre- and post-test using the 13-item patient activation measure. Parametric statistical models (t test, ANOVA, ANCOVA) were applied to draw inferences.

Results: The web-based intervention demonstrated a positive and significant effect on the patient activation levels of participants in the intervention group. A significant difference in posttest patient activation scores was found between the two groups (F 1,123 = 4.438, P = .037, r = .196). Patients starting at the most advanced development of patient activation (stage four) in the intervention group did not demonstrate significant change compared to participants beginning at earlier stages.

Conclusions:  This is the first known study to measure change in patient activation when a web-based intervention is used by patients living with different chronic conditions. Results suggest that web-based interventions increase patient activation and have the potential to enhance the self-management capabilities of the growing population of chronically ill. Activated patients are more likely to adhere to recommended health care practices, which in turn leads to improved health outcomes. Designing web-based interventions to target a specific stage of patient activation may optimize their effectiveness. For web-based interventions to reach their potential as a key component of chronic disease management evidence is needed that this technology produces benefits for a sustained period among a diverse population.
