How does the AFEQT support physicians?

AFEQT evaluates health-related quality of life (HRQoL) and provides an overall score; plus scores for symptoms, daily activities, treatment concerns, and treatment satisfaction.



  • Validated questionnaire that was patient derived with expert clinical input
  • Reliable: Cronbach's alpha coefficients for the global and subscales scores of the AFEQT questionnaire >0.8 indicating internal consistency
  • Responsive: Moderate to large effect size observed for AFEQT scores following treatment intervention demonstrates responsiveness of AFEQT questionnaire
  • Easy-to-use: 20 questions on 7-point Likert scale
  • Five-minute completion time

Score interpretation

Overall or subscale scores range from 0-100.

A score of 0 corresponds to complete disability (or responding “extremely” limited, difficult or bothersome to all questions answered), while a score of 100 corresponds to no disability (or responding “not at all” limited, difficult or bothersome to all questions answered).
