Background: Leisure activities are an important part of activities that people with Multiple Sclerosis do in their life. As a while, unfortunately, there are not any proper assessment tools for evaluation of it. The purpose of this research is to develop a leisure questionnaire and finding the factor structure of it for Multiple Sclerosis patients.
Methods: This psychometric study in order to find the factor structure of the leisure questionnaire was conducted in two explanatory and confirmatory phases.
Results: The leisure questionnaire was filled up and data was entered in SPSS for the explanatory phase and LISREL for the confirmatory phase. The lowest Eigenvalue is 1.01, which corresponds to the Kaiser criterion. The validity coefficients of the extracted factors are considerable. There is a very slight difference between the highest coefficient that is related to the third factor (0.846) and the lowest coefficient that is related to the fifth factor (0.799), indicating correct determination of the number of factors. Confirmatory factor analysis illustrated that the GFI and CFI indices were considerable (higher than 0.95), showing good fit of data. Also RMSEA was 0.024.
Conclusion: It can be concluded that the 5-factor structure (difficult, social, spiritual/religious, outdoor-physical and cultural-artistic activities) of multiple sclerosis leisure questionnaire with 50 items is confirmed.
