Comparison of Rated and Ranked Health and Lifestyle Values
Objective: Values are typically ranked; however, ratings have desirable administrative and statistical properties. The purpose of the present study was to determine the better format to measure health and lifestyle values: traditional ranking or Likert-type rating. Methods: Psychometric properties of the two survey formats were compared on a sample of 183 first-year university students. Results: The ranking format had higher one-week test-retest reliabilities than did ratings (median .66 vs .60) but consistently lower validities when compared to self-report health behaviors. Conclusion: Results: from the present study suggest that a rating format for health and lifestyle value items should be used. Am J Health Behav 1999;23(5):356-367 |
