The purpose of this study is to learn more about how chronic low back pain patients choose between different treatment options.

This study is supported with funding from the National Institutes of Health (NIH).

Approximately 300 patients will be taking part in this study.

• The fifth section will ask you to imagine yourself choosing a new therapy for your chronic low back pain. A handout with descriptions of different factors to consider will be given to you. You will then be presented with two different options and will be asked to choose which one you like best 16 to 20 times with the factors differing each time. This section will take you about 10 minutes to complete.
• After completion of all four sections you will be asked a few follow-up questions about taking the survey.
• Leslie Wilson may contact you by phone, email, or mail at a later point in time if she has any further questions about your answers or participation.
• Study location: All these procedures will be done at a UCSF-affiliated campus or online on the internet.

Participation in the study will take a total of about 40 minutes.
