Aims: This study aimed to psychometrically evaluate the Turkish version of the Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-15) in women with MS.

Methods: The study included 130 women with MS. The Turkish linguistic validation process of the original English MSISQ-15 was performed according to standardized guidelines. Reliability analysis was evaluated with test-retest analysis and intra-class correlation (ICC). Internal consistency between the items was analyzed using the Cronbach's alpha coefficient. Item analysis results were used to assess the contribution of the items to the scale. In evaluating the validity of the scale, the relationship between the MSISQ and the Female Sexual Function Index (FSFI), the Multiple Sclerosis Quality of Life Questionnaire-54 (MSQOL-54), and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PSIQ-12) was investigated. Psychometric properties were analyzed using internal consistency, test-rest reliability, construct validity, and floor-ceiling effect.

Inclusion Criteria:

• Women over the age of 18 who were literate,
• who did not have any mental problems preventing cooperation and understanding,
• who were diagnosed with MS

Exclusion Criteria:
