Introduction:
The goal of the present study was to develop a short version (SV) of the Quality of Life Relevance-Acne (QOLRELEVANCE-ACNE) based on the identified most relevant items for acne patients.
Methods:
Members of the international internet group for acne patients were asked to fill in the short prototype version of the QOLRELEVANCE-ACNE. Internal consistency was measured using Cronbach's alpha.
Results:
The answers of 684 acne patients were collected. The analysis revealed that the internal consistency of the instrument could be improved by removing a single item. That item was removed and the final four-item short version of the QOLRELEVANCE-ACNE-SV was formed. There is minimal or no overlapping of the QOLRELEVANCE-ACNE-SV with other brief forms of acne-specific HRQoL instruments.
Conclusion:
The four-item QOLRELEVANCE-ACNE-SV questionnaire was developed and showed good internal consistency. An international validation study of the QOLRELEVANCE-ACNE-SV will be performed.
