Background The last decades have witnessed an increasing interest for the psychosocial aspects of chronic skin diseases, such as psoriasis. Nonetheless, systematic assessments of the impact of psoriasis on patients' lives are rarely done in daily clinical practice. The existing instruments are mostly meant to be completed by patients alone, and rarely comprise a graphical representation of the results. Objective To develop a questionnaire allowing both a quick assessment of the impact of psoriasis on patients and, at the same time, an intuitive graphic visualization of the outcome of the test. Methods A preliminary version of an Italian questionnaire aimed to assess the global impact of psoriasis on patients, meant to be filled in together by the patient and the dermatologist and to produce visual, intuitive results, was developed through focus groups. The instrument was then the object of a Delphi survey addressed to a panel of experts, to assess both the need of possible improvements of the questionnaire (in terms of the formulations of the questions and of the domains to be explored) and the usefulness of the questionnaire. Results A 10-item questionnaire in Italian, taking into account different aspects of the burden of psoriasis on the patient, was developed. The answers are given on a 10-point visual analogue scale and graphically represented on a disc as a polygon. Conclusions A formal validation of the questionnaire and a study to assess potential clinical and psychological benefits of a systematic implementation of the instrument in daily practice are planned.
