Brief Summary
The purpose of this study is to develop a conjoint analysis-based questionnaire and decision aid for patients with osteoarthritis of the knee and to compare the responses of two groups of subjects, one receiving only printed information about knee osteoarthritis, the other participating in a computer-based adaptive conjoint analysis program.

Outcome Measures
Primary Outcomes (1)
Change in osteoarthritis treatment (for instance, change from an NSAID to capsaicin cream) as measured by follow-up telephone interview
4 weeks
Secondary Outcomes (1)
Ease of use, understandability, and suggestions for improvement of the computer decision aid
same day
Study Arms (2)
Usual Care
Patients randomized to the control group will be sent the post-test measures suitably modified to reflect the fact that they did not participate in the conjoint analysis program. Four weeks after the post-test measures are completed, a staff member will call the subject to complete a 10 minute follow-up questionnaire to assess if any changes in treatment have occurred and to take further measurements (same measurements given to treatment group).
Conjoint Analysis Group
Patients randomized to the experimental group will meet the research staff to complete the conjoint analysis software and post-test measures. The post-test measures include preparedness for decision-making, personal uncertainty, osteoarthritis knowledge, arthritis self-efficacy, and satisfaction with the results of the conjoint analysis program. The in-person visit takes approximately 60 minutes to complete. Four weeks after the in-person visit, a staff member will call the subject to complete a 10 minute follow-up questionnaire to assess if any changes in treatment have occurred and to take further measurements (i.e. global pain assessment, arthritis self-efficacy, personal uncertainty, and osteoarthritis knowledge).
Interventions
Standard of care educational materials to inform patients about choices for knee pain.
Conjoint Analysis computer software to inform patients about choices for knee pain.
