Abstract

Objective: This study aims to test the validity and reliability of the Chinese version of the Disease-Related Fear Scale (D-RFS) in order to understand the experience of fear in patients with epilepsy (PWE).

Methods: The researchers obtained translation permission and followed international guidelines to develop a Chinese version of the D-RFS. A total of 609 PWE were recruited from a general tertiary hospital in Hangzhou, China, between January 2023 and June 2023. We evaluated the psychometric properties of the D-RFS, including content validity, reliability, test-retest reliability, internal consistency, and construct validity.

Results: Exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) were conducted on two separate samples with a sample size of 307 and 302. The results of EFA indicated that the scale could be divided into three dimensions, which were supported by the structure in CFA. We named the three dimensions as follows: "fear of seizure consequences", "fear of poor epilepsy management", and "fear of social restrictions", respectively. The Cronbach's alpha coefficient for the entire scale was 0.960, with a coefficient of 0.907, 0.953, and 0.917 on three dimensions.

Conclusion: The Chinese version of the D-RFS was found to be an effective and reliable tool to measure the experience of fear in adult PWE in China. The study could lay the foundation for future investigations to explore associated factors of epilepsy-related fear and establish intervention strategies to alleviate patients' fear in clinical practice.
