For years, there has been interest in sexual dysfunction and its impact on quality of life but usually focused on one gender. Therapeutic options that became available raised the interest to evaluate effects on the other partner but there is no standardized instrument applicable for both genders. This paper reports first data regarding the development of a new general "Quality of Sexual Function" (QSF) scale. ⋯ This self-administrable 40-item QSF scale can measure and compare quality of sexual function for both genders. The scale was well accepted by the respondents. It is easy to answer and the evaluation is simple. Only a few results of reliability and validity have been established in this early stage of the development of the new instrument. Further research is needed to complete many missing aspects of reliability and the construct validity, particular its sensitivity to treatment effects.
