The effect of erectile dysfunction on quality of life: psychometric testing of a new quality of life measure for patients with erectile dysfunction.

Purpose: We assessed the psychometric properties of the newly developed Erectile Dysfunction Effect on Quality of Life (ED-EQoL) instrument for quantifying the effect of erectile dysfunction on quality of life.

Materials And Methods: The questionnaire was assessed in a cohort of 283 men recruited from 11 centers in the United Kingdom. Internal consistency was examined by Cronbach's alpha, test-retest reliability was determined by administering the instrument on 2 occasions 2 weeks apart without treatment in the interim, construct validity was assessed by comparison with other quality of life measures and responsiveness was evaluated by comparing the change in the ED-EQoL after treatment with change in other measures.
