The psychosocial effects of facial acne are well accepted but until recently few validated instruments existed which were suitable for use in clinical trials. The aim of this study was to assess measurement characteristics (reproducibility, correlation with acne severity, and sensitivity to detect change after acne therapy) of a new acne-specific quality of life instrument, the Acne-QoL. We found that the Acne-QoL is reliable, valid and able to distinguish differences across severity groups and improvement over 16 weeks of standard therapy. The use of the Acne-QoL should aid physicians in understanding the impact of facial acne on young adults, and may be useful in assessing therapeutic effects in acne clinical trials.
