Skin-Related Sexual Life Questionnaire (SRSLQ): Creation and Validation of the Questionnaire

Background and Objectives: The assessment of sexual dysfunction among psoriatic patients still remains a great diagnostic difficulty due to its subjective and embarrassing character. Various questionnaires have been used to assess sexual dysfunctions associated with skin conditions; however, none of them have been approved as a gold standard. The aim of our study was to create and validate the Skin-Related Sexual Life Questionnaire (SRSLQ) for the assessment of possible sexual dysfunction and related psychological burdens in patients with skin diseases. Materials and Methods: A total of 109 patients, including 45 women and 64 men (1:1.4) suffering from psoriasis and aged between 18 and 73 years (mean 48.0 ± 13.4 years), were included in the study. All subjects completed the 11-item SRSLQ and the Dermatology Life Quality Index (DLQI). In addition, all men were asked to fulfil the five-item version of the International Index of Erectile Dysfunction (IIEF-5) at the time of examination and 7 days after enrollment. The disease severity was assessed via the PASI scale. Results: The statistical analysis of internal consistency of SRSLQ showed very good integrity, with a Cronbach α coefficient of 0.94. The reproducibility level assessed with intraclass correlation coefficient (ICC) amounted to 0.96. A significant correlation between the total score of the 11-item SRSDQ and the DLQI (r = 0.39; p < 0.001) was found, confirming congruent validity. Conclusions: The validated 11-item Skin-Related Sexual Life Questionnaire can be successfully implemented in daily clinical practice as well as in clinical research.
