Dutch translation and psychometric assessment of the PROMIS® Sexual Function and Satisfaction measure version 2.0 in the general population

Sexual functioning and satisfaction are important aspects of daily life and are associated with healthrelated quality of life.The Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction (PROMIS SexFS) has been developed, a promising measure to gain insight into the various domains of sexual functioning and satisfaction.Originally developed in the U.S., this study aimed to translate and culturally adapt components of the PROMIS SexFS into Dutch and evaluate its psychometric properties and feasibility in the general population. J o u r n a l P r e -p r o o fSelected components of the PROMIS SexFS (screener, five calibrated and scored measures, one calibrated and unscored measure, one uncalibrated and scored measure, and five uncalibrated and unscored measure) were translated using standardized forward-backward procedures, and cognitive testing.Consensus was reached on translation issues, although some adjustments to realize full inclusivity were impossible.Items were completed online by 1,433 individuals from the general population.The scored and calibrated item banks were psychometric evaluated.Psychometric analyses indicated sufficient structural validity with four of the 22 items showing misfit with negligible impact on scores.One item did not meet the assumption of monotonicity.Reliability was high across the relevant score range.The collected reference data provide valuable insights for interpreting scores and understanding sexual functioning and satisfaction.Concluding, the PROMIS SexFS was successfully translated and adapted for use in the Netherlands, showing reliability and validity, comparable to the U.S. version, and suitability for research and clinical practice.
