Aims: The Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-15) evaluates symptoms of sexual dysfunction in patients with multiple sclerosis (MS). The objective of this study was to provide and validate a Dutch version of the MSISQ-15 in patients with neurological disease such as MS and spinal cord injury (SCI). Methods: The linguistic validation process of the original English MSISQ-15 into Dutch was performed according to standardized guidelines. Sexually active patients with MS or spinal cord disorders, including SCI and cauda equine syndrome, who visited a tertiary urology center or a rehabilitation center completed the MSISQ-15, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in women, or International Index of Erection Function (IIEF-15) in men at baseline (test) and 2 weeks later (retest). A reference group recruited from a general medical practice completed the questionnaires once. Data were analyzed for measurement properties. Results: Fifty-three patients with MS, 49 patients with spinal cord disorder, and 50 references were included. Content validity was adequate. Internal consistency (Cronbach's alpha >0.8) and reproducibility (intraclass correlation coefficient >0.8) of the MSISQ-15 were excellent. Patients’ MSISQ-15 scores were correlated with severity of symptoms of sexual dysfunction measured by PISQ-12 or IIEF-15 and confirmed positive rating for criterion validity. MSISQ-15 scores in patients were higher than in references (on a scale of 15-75: 38.9 ± 11.4 vs 21.1 ± 5.4; P < 0.001), indicating good construct validity. Conclusions: The Dutch MSISQ-15 is a reliable and valid measure to evaluate symptoms of sexual dysfunction in patients with MS or with SCI.
