Abstract Category: Clinical aspects of MS - Epidemiology
Background: As Multiple Sclerosis (MS) prevalence is increasing in Iran and designing a national registry system is needed.
Objective: We aimed to design a valid and reliable MS registry form, to utilize in MS minimum dataset.
Method: The population-based minimum dataset form consists of six subgroups including patient identification, family history of MS, disease course and diagnosis, disability status and Medication with related questions.
The pilot study was done to evaluate validity and reliability. The content validity was assessed based on 27 experts' opinions. Item-content validity index (i-CVI) and scale-content validity index (s-CVI) were used to assess question and the whole form validities, respectively. Test-retest reliability was also assessed by using intra-class correlation coefficient (ICC).
Statistical analysis was done by using SPSS.
Results: Totally 74 patients were recruited for the pilot study.
For validity 27 experts reviewed the form. The critical value for CVI was considered 0.78 based on literature review. All items had i-CVI>0.78 in relevance, clarity and simplicity (In 18 items out of 20,20 out of 20, and 19 out of 20, respectively) except for “Each medication start date and end date” in relevance (i-CVI=0.75 and 0.73, respectively), and “MS type” in simplicity (I-CVI=0.76). S-CVI scores for relevance, clarity and simplicity were all > 0.9.
Reliability: 27 patients (Out of 74 interviewed patients) were re-interviewed to assess test-retest reliability. The critical value for ICC was considered 0.7 based on literature review. ICCs were all >0.7 (In 14 items out of 16) except for progression to secondary-progressive MS and reason for medication discontinuance (ICC=0.68 and 0.64, respectively).
Conclusion: The use of standardized validated questionnaires will assist the researchers and policy makers to perform national registry system based on standard form. The minimum dataset form of MS registry had suitable validity and reliability to be used.
