RESUMO
BACKGROUND: People with multiple sclerosis (MS) may experience sexual dysfunction throughout the disease course. Validated scales to assess sexual dysfunction in MS for Italian patients are lacking. Hence, we aimed at validating Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-19) for Italian MS patients. METHODS: We included both male and female MS patients. Each patient completed the Italian translation of the MSISQ-19. Construct validity was explored by the exploratory factor analysis and the Cronbach's alpha coefficient. Test-retest stability and concurrent internal and external validity were examined by Pearson' correlation coefficients. RESULTS: We enrolled 369 MS patients (323 female and 46 male). Italian MSISQ-19 showed a Cronbach's alpha of 0.92. MSISQ-19 test and retest total scores correlated between each other (r = 0.48, p = 0.01). MSISQ-19 total score also correlated with primary, secondary and tertiary subscales (p < 0.001). CONCLUSION: The Italian Version of the MSISQ-19 showed satisfactory internal consistency and reliability with moderately adequate test-retest reproducibility, suggesting that it may be used as a valuable measure of sexual dysfunction in the Italian population.

BACKGROUND: Patients with multiple sclerosis (MS) especially those with younger age experience an alteration in physiological and emotional lifestyle that can affect intimacy and sexuality. The aim of this study was to determine demographic and disease related determinants of intimacy and sexuality in young women with MS. METHODS: This was a cross sectional study carried out in Tehran, Iran. A convenience sample of young women aged ≤35 years old with MS attending to outpatient clinics in a teaching hospital affiliated to Tehran University of Medical Sciences was entered into the study. The Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19) was used to evaluate how the disease influences sexual function and satisfaction in these patients. Multivariable analysis using hierarchical method was performed to identify variables that are associated with intimacy and sexuality. RESULTS: In total 117 young women with confirmed diagnosis of MS were included in the study. Participants mean was 25.7 (SD = 8.07) years. A multivariable hierarchical regression analysis was performed using demographic variables entered in step one, relevant neurological variables in step two, and psychological variables in step three. Furthermore, we loaded antidepressant use in the last step. Overall, the seven variables accounted for 39% of total variance observed for the MSISQ score (P < 0.001). At step one the demographic variables accounted for 13% of the variance in the MSISQ score (P < 0.001). At step two the inclusion of relevant neurological variables increased the R2 significantly and explained 27% of variance for the MSISQ (P < 0.001). However in the third step the inclusion of psychological factors increased R2 significantly (adjusted R2 increased to 0.39, P < 0.001). CONCLUSIONS: The findings indicated that psychological, disease-related and demographic factors (education and employment status) contributed to intimacy and sexuality in young women with multiple sclerosis. Appropriate interventions, especially psychological interventions, appear to be essential immediately following a definite MS diagnosis in young women.

INTRODUCTION: The Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19) was designed to assess the perceived influence of multiple sclerosis (MS) symptoms on sexual activity and satisfaction. AIMS: This study aimed to translate and validate the MSISQ-19 in women with MS in Iran. METHODS: The translation of the original questionnaire was carried out in accordance with a standard forward-backward procedure. Then, a sample of 226 married women with MS completed the questionnaire. Reliability was estimated using Cronbach's alpha coefficient. Concurrent validity was assessed by comparison with the Female Sexual Function Index (FSFI), the Expanded Disability Status Scale (EDSS), and the Beck Depression Inventory-II (BDI-II). The factor structure of the questionnaire was extracted by performing exploratory factor analyses. All patients underwent a full neurologic examination. MAIN OUTCOME MEASURES: MSISQ-19 score was the main outcome measure. RESULTS: The mean age of participants was 35.77 years (SD = 8.07), with mean disease duration of 1.84 years (SD = 0.79). Cronbach's alpha coefficient was 0.90 for total MSISQ-19 score, with values of 0.85, 0.90, and 0.78 for the subscales assessing primary, secondary, and tertiary sexual dysfunction, respectively. The principal component analysis indicated a three-factor solution, similar to that found in the original validation study, that explained 63.0% of the total variance for women with MS. Scores on the MSISQ-19 and its subscales correlated with scores on the FSFI, EDSS, and BDI-II (all P < 0.01). CONCLUSION: In general, the findings suggest that the MSISQ-19 is a reliable and valid measure of sexual function among Iranian women with MS. However, further studies are needed to establish psychometric properties for male MS patients in Iran.

BACKGROUND: Sexual dysfunction (SD) is a common reported problem in patients with multiple sclerosis (MS). AIMS: to examine frequency and distribution of SD dimensions and to determine whether SD is related to various clinical and demographic variables in female patients. MATERIALS AND METHODS: A total of 271 MS women (age: 19-50 years) participated in this cross-sectional study. We used a structured demographic and clinical interview and Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19). Disability was rated by Expanded Disability Status Score (EDSS). RESULTS: 63.5% (n = 173) of women had SD included 142 (52.4%) women with primary SD, 102 (37.5%) women with secondary SD and 120 (41%) women with tertiary SD. The most common SD-related complaint was orgasmic problem (41.2%). Women with primary SD were significantly older and had higher EDSS score. No significant relationship was found between primary SD and disease duration. Fatigue (OR = 2.69, 95% CI: 1.352-5.385, P = 0.005), memory and concentration complaints (OR = 1.915, 95% CI: 1.034-3.546, P = 0.039) and some of urinary symptoms such as frequency (OR = 2.108, 95% CI: 1.015-4.375, P = 0.045) were seem to be the significant predictors. Fatigue was also found to be the most powerful predicting factor for tertiary SD (OR = 2.793, 95% CI: 1.358-5.744 P = 0.005). CONCLUSION: SD, a common multifactorial problem among MS women, can arise at any time during the disease and with any level of disability. However, we found relationships between SD and some of clinical variables and symptoms. Understanding these relationships would help us to develop practical approach and treatment for SD.
RESUMO
BACKGROUND: Although multiple sclerosis (MS) Intimacy and Sexuality Questionnaire-19 (MSISQ-19) is a widely applied tool, no unique definition of sexual dysfunction (SD) based on its score exists. OBJECTIVE: To explore the impact of different MSISQ-19 cut-offs on SD prevalence and associated risk factors, providing relevant information for its application in research and clinical settings. METHODS: After defining SD according to two different MSISQ-19 cut-offs in 1155 people with MS (pwMS), we evaluated SD prevalence and association with sociodemographic and clinical features, mood status and disability via logistic regression. RESULTS: Depending on the chosen cut-off, 45% to 54% of pwMS reported SD. SD defined as MSISQ-19 score >30 was predicted by age (OR=1.01, p=0.047), cognition (OR=0.96, p=0.004) and anxiety (OR=1.03, p=0.019). SD defined as a score >3 on any MSISQ-19 item was predicted by motor disability (OR=1.12, p=0.003) and cognition (OR= 0.96, p=0.002). CONCLUSION: Applying different MSISQ-19 cut-offs influences both the estimated prevalence and the identification of risk factors for SD, a finding that should be considered during study planning and data interpretation. Preserved cognition exerts a protective effect towards SD regardless from the specific study setting, representing a key point for the implementation of preventive and therapeutic strategies.
RESUMO
INTRODUCTION: Patients with multiple sclerosis (MS) suffer from various symptoms, including sexual dysfunction. The Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19) is a scale that explores the impact of MS on sexual activity and satisfaction. AIM: This observational cohort study aimed to provide a validated, cross-cultural, French version of the MSISQ-19 in patients with MS. METHODS: The original version of MSISQ-19 was translated into French according to standardized guidelines. Patients were asked to complete all questionnaires during the inclusion visit and the MSISQ-19 a second time two weeks later. Content validity was assessed by face validity. Internal consistency was evaluated using Cronbach's alpha. Construct validity was checked by the exploratory factor analysis. Concurrent validity was assessed by performing Spearman's correlation coefficient with the Female Sexual Function Index (FSFI), the Male Sexual Health Questionnaire (MSHQ), and the Multiple Sclerosis International Quality of Life questionnaire (MusiQoL). Spearman's correlation coefficient was also used to evaluate the relationship with the Expanded Disability Status Scale (EDSS), age, and disease duration. Test-retest reliability was assessed by intraclass correlation coefficient (ICC). Responsiveness was assessed by the standard error of measurement (SEM) and the minimum detectable change (MDC). MAIN OUTCOME MEASURES: MSISQ-19 is the main outcome measure. RESULTS: We enrolled 71 patients with MS (49 female, 22 male). The mean age was 42.6 ± 9.7 years with a median disease duration of 8 [3-16] years. Sixty-four (90%) patients had relapsing-remitting MS, 4 (6%) primary progressive MS, and 3 (4%) secondary progressive MS. French MSISQ-19 showed a Cronbach's alpha coefficient of 0.89. MSISQ-19 scores correlated significantly and moderately between each other and correlated significantly and moderately with scores on the FSFI, MSHQ, MusiQoL and EDSS. Reproducibility was excellent with intraclass correlation coefficients > 0.80. Exploratory factor analysis was performed using principal component analysis. A three-factor solution was adopted giving eigenvalues higher than 1, supporting the primary, secondary, and tertiary dimensions. SEM was 4.55 and MDC was 12.6 (13.3%). CONCLUSION: This study provides a preliminary validation of the French version of the MSISQ-19 which could be a reliable, and reproducible instrument to assess sexual dysfunction in patients with MS. These results need to be confirmed in a larger cohort which will be more representative of the general MS population.
