title: Identifying correlates of young adults' weight behavior: survey development.
abstract: OBJECTIVE
  To describe the development and psychometric properties of survey measures relevant to eating, physical activity, and weight-related behaviors among young adults.
  
  
  METHODS
  Focus groups and reliability testing guided the development of the Project EAT-III survey.  The final survey was completed by 2287 young adults.
  
  
  RESULTS
  The systematic process employed led to a psychometrically sound and developmentally appropriate survey. Test-retest reliabilities for items included on the final survey were mostly moderate to good, and Cronbach alphas were  >0.7 for 83% of developed scales.
  
  
  CONCLUSIONS
  Future studies may find the systematic process used to be helpful in creating other weight-related surveys.
