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.
