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. Method 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. Conclusion The application of the EDQOL as an outcome measure in eating disorder research is considered. © 2005 by Wiley Periodicals, Inc.
