Diagnostic Odyssey Survey 2

Odyssey2 will retain the strengths (simplicity, brevity, confidentiality, and data quality assurance measures) which made Odyssey1 successful. While Odyssey2 adds some refinements based on experience learned from Odyssey1, the basic questions are changed as little as possible to maximize comparability, and the additions are limited. Odyssey1 consisted of between 16 and 23 questions, depending on skip patterns, and took an estimated 15 minutes to complete. Odyssey2 consists of between 23 and 33 questions, depending on skip patterns and we estimate that it will take approximately 20 minutes to complete.
