Risk and Risk Perception of Knee Osteoarthritis in the US

NCT02704286 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 380

No results posted yet for this study

Summary

The investigators have created an interactive knee osteoarthritis (OA) risk calculator that estimates a user's risk of developing symptomatic knee OA as well as the user's risk for undergoing a total knee replacement (TKR) within their lifetime. To test the impact of the calculator, the investigators recruited OA-free subjects from Amazon's Mechanical Turk. Participants were randomized to either access general information about OA or use the risk calculator in addition to accessing general OA information. The investigators hypothesized that participants randomized to the risk calculator arm would have more accurate perception of their knee OA risk and would have increased willingness to change risky behavior compared to the general OA information group.

BEHAVIORAL

Internet-Based Osteoarthritis Risk Calculator

The investigators have developed a personalized risk calculator for knee osteoarthritis. This risk calculator uses the Osteoarthritis Policy Model to estimate an individual's risk of developing knee osteoarthritis within their lifetime based on demographic information and risk factors. It shows this information to the user with interactive graphs and compares their risk to the risk of an average American of the same age.

BEHAVIORAL

Generic osteoarthritis information

Subjects viewed generic (i.e. not personalized) information about osteoarthritis risk factors
