Abstract
Epilepsy, particularly in older people, is associated with significant changes in physical activities, social and occupational functions, and diet. It is associated with significant changes in physical activities, social and occupational functions, and diet. Valid and reliable instruments are needed to assess these changes. This study aimed to develop and validate a questionnaire to assess lifestyle in older people with epilepsy, named the Epilepsy Lifestyle Questionnaire (ELQ). This methodological study was conducted in 2022. The primary ELQ items were generated through reviewing the literature. Then, its face, content, construct, convergent, and discriminant validity, internal consistency, and test-retest stability were evaluated. Older patients aged ≥ 60 years were recruited from the Iranian Epilepsy Association to assess construct validity using confirmatory factor analysis (CFA). Data were analyzed using the SPSS (v. 26.0), AMOS (v. 24.0), and JASP software. The primary ELQ had 99 items with five subscales, namely health-oriented self-care, risk-averse behavior, emotional and psychosocial adaptation, epilepsy stigma, and intimacy and sexual behaviors. Sixty five items were deleted during psychometric evaluation. CFA showed the good fitting of the five-factor structure of the 34-item ELEQ (PCFI = 0.741, PNFI = 0.693, CMIN/DF = 0.073, IFI = 0.917, CFI = 0.916, AND GFI = 0.902). The values of internal consistency based on Cronbach's alpha and test-retest reliability based on intraclass correlation coefficient (ICC) of ELQ were 0.89 and 0.95, respectively. The ELQ is a valid and reliable self-report instrument. The results suggest that the ELQ is a useful clinical tool for assessing the lifestyle of patients with epilepsy.
