The Social and Occupational Functioning Scale for Epilepsy (SOFSE): A brief measure of functional status in a Taiwanese sample with epilepsy

Summary Purpose To develop and validate a scale of social functioning for people with epilepsy (PWE)—the Social and Occupational Functioning Scale for Epilepsy (SOFSE). Methods According to the literature review and opinions from a panel of experts, PWE, and caregivers, a total of 31 questions were compiled. Questionnaires were analyzed from 172 adults with epilepsy. Key Findings The final scale had 30 items in six dimensions. The results showed that internal consistency coefficients and test–retest reliabilities for each dimension ranged from 0.70 to 0.84 and 0.72 to 0.89, respectively. Retest reliability for the total SOFSE score was 0.92. Seven factors were extracted through principal factor analysis. Moreover, criterion-related validity was demonstrated by the significant correlations between the SOFSE and the following measures: the Mini Mental Status Examination (r = 0.60, p
