The Twin Cities Walking Survey was developed for a Round 2 Active Living Research grant in St. Paul, Minnesota, for which Ann Forsyth is the principal investigator. At the 2004 ALR conference, all round 2 grantees with projects focused on community and correlates of physical activity gathered for a meeting to discuss common measures. The Twin Cities Walking Study is the result of that discussion. Ann Forsyth’s crew led the effort to compile this instrument mostly because we were the first in the field. The sources for the questions are listed in the reference list. It takes approximately 45 minutes to complete the survey as an interview. Pilot testing with 40 racially diverse volunteers in Minnesota indicated that most sections take less than 3 minutes to complete, with a few notable exceptions such as the IPAQ and demographics sections.
