title: Development and psychometric validation of an eating disorder-specific health-related quality of life instrument.
abstract: OBJECTIVE
  Health-related quality of life (HRQOL) has been used increasingly as an outcome measure in clinical research. Although the generic quality of life instruments has been used in previous research, disease-specific instruments offer greater sensitivity and responsiveness to change than generic instruments. No such disease-specific instrument is currently available that applies to eating-disordered samples.
  
  
  METHODS
  The current article reports on the development and validation of the Eating Disorders Quality of Life (EDQOL) instrument, a disease-specific HRQOL self-report questionnaire designed for disordered eating patients.
  
  
  RESULTS
  The EDQOL demonstrates excellent psychometric properties.
  
  
  CONCLUSIONS
  The application of the EDQOL as an outcome measure in eating disorder research is considered.
