Impact of being a relative of a patient with epilepsy on the association of attitudes toward epilepsy and disease knowledge levels.

Objective: The social prognosis for individuals with epilepsy is often poorer than their clinical prognosis, highlighting the significant influence of social factors on the progression of the disease. Relatives of patients with epilepsy (RPEs) generally have more positive attitudes towards epilepsy compared to the general population. This study aimed to examine the effect of being an RPE on the relationship between attitudes toward epilepsy and levels of disease knowledge.

Methods: This cross-sectional analytical study included 217 adult participants, comprising 93 RPEs and 124 controls (non-RPEs), selected through convenience sampling. Data were collected via face-to-face interviews using a questionnaire that included sections on socio-demographic characteristics, the Epilepsy Knowledge Scale, and the Public Attitudes Toward Epilepsy (PATE) Scale. Path analysis was conducted using the Maximum Likelihood method. Due to the non-normal distribution of exogenous variables, the robust Huber/White/sandwich estimator method was used to calculate confidence intervals and fit indices.

Results: The mean age of the participants was 34.7 ± 11.5 years, with 128 (59.0 %) being female. RPEs scored an average of 26.8 ± 9.9 on the PATE Scale, which was significantly lower than the average score of 29.7 ± 11.0 for non-RPEs (p = 0.047). Path analysis indicated that being an RPE indirectly fosters a positive attitude through increased knowledge levels. While the direct effect of being an RPE on attitudes was not statistically significant, the indirect effect mediated by knowledge was significant.

Significance: This study highlights that the level of knowledge about epilepsy, a key predictor of positive attitudes, remains important even among RPEs. In kinship contexts where neurobiological and psychosocial factors are at play, the primary determinant of attitudes toward epilepsy is still the level of knowledge about the condition. Consequently, focusing on increasing knowledge about epilepsy should be the main strategy to promote positive attitudes, providing a more promising avenue for future research and interventions.
