Longitudinal investigation into implicit stigma of epilepsy among Japanese medical students before and after mass media coverage of car accidents associated with people with epilepsy

Internet survey on knowledge and perceptions of epilepsy among the general public in Japan

Objective

To improve the life quality of people with epilepsy, it is necessary to provide comprehensive epilepsy care and disseminate accurate information related to epilepsy to the public. In Japan, reports of traffic accidents involving people with epilepsy started to draw attention in the media in 2011. Ever since that, the association between the image of epilepsy from the general public, "Epilepsy," and "Danger," was more robust in 2013. Since 2017, no previous surveys have examined the perceptions and knowledge of epilepsy among the public in Japan. As an essential source of information for epilepsy care, we conducted a nationwide Internet-based survey to elucidate the current state of knowledge and perceptions of epilepsy among the public without epilepsy in Japan.

Methods

We conducted an online survey from July 29 to August 2, 2021, with 213 respondents (115 male, 97 female, and one unidentified; mean age: 50.52 ± 12.34 years) registered with an online survey service in Japan. In this survey, we first questioned whether or not a respondent had epilepsy, and then those with epilepsy were excluded from participation. We collected basic demographic information, administered the Epilepsy Knowledge Scale (18 items), and asked the open-ended response question, "What kind of disease do you think epilepsy is? If you do not know, please describe epilepsy in your words." We adopted quantitative text analysis using KH Coder3 and co-occurrence network analysis to examine the connections between words.

Results

Among the respondents, 92% have heard of epilepsy, and 26.8% have observed an epileptic seizure before the survey. The knowledge scale yields an average score of 27.96 ± 21.3 (out of 100), with the question with the highest percentage of correct responses being "People with epilepsy are just as capable as other people" at 51.64%. The question with the lowest percentage of correct responses was "If the person with epilepsy only has seizures during sleep, the person can have a driver's license," at 9.85%. The average number of Japanese characters responding to open-ended text questions was 10.45 ± 8.87 characters (including Kanji, Hiragana, and Katakana). We found that the word "froth" appeared more frequently with experience of observing a seizure, and the words "occur" and "brain" appeared more frequently with higher knowledge of epilepsy. Furthermore, comparing the sources of information from what they learned about epilepsy, the words "seizure," "faint," and "consciousness" appeared more frequently in school, with family and friends, and in newspapers and television, respectively.

Conclusion

We identified the level of knowledge and perceptions of epilepsy among the general public in Japan in 2021. By analyzing the qualitative aspects of open-ended text responses, we gathered information that might be useful for informing the public of future efforts to provide accurate information related to epilepsy.

Public awareness and experiences associated with epilepsy in Japan, 2013-2017

BACKGROUND

Public attitudes and stigma toward epilepsy may limit people with epilepsy (PWE) in seeking treatment and participating in social activities. The prevalence of epilepsy is approximately 0.8% in Japan, similar to rates reported in other countries. Although epilepsy is relatively common, few studies have investigated public awareness about epilepsy in Japan. Recently, several serious car accidents in Japan involving PWE resulted in pedestrian fatalities. Traffic accidents involving PWE have been reported extensively and repeatedly in the media since 2011. In 2013 and 2017, our research group conducted a large investigation of awareness about epilepsy targeting the general public. Previous studies have reported that knowledge is one of the factors involved in improving attitudes and reducing stigma. The aim of the current study was to compare survey results, especially regarding knowledge of epilepsy, and capture changes in public awareness between 2013 and 2017.

METHODS

A total of 2160 people (1080 in each year) participated, with a total of 540 women in each year, aged 20-79 years. Participants lived in the greater Tokyo area as well as the Tohoku and Kansai regions of Japan. All participants answered survey questions online in January 2013 and April 2017. We analyzed five questions regarding the participants' demographic data, nine questions regarding knowledge about epilepsy, and five questions regarding experiences with epilepsy. For questions investigating the respondents' knowledge about epilepsy, we counted only the correct answers and scored these for each respondent.

RESULTS

Knowledge scores decreased from 2013 to 2017, demonstrated by statistical analysis. However, the effect size was very small. Knowledge scores among the following groups were higher in both 2013 and 2017: people who had read or heard about epilepsy, those who had witnessed people having an epileptic seizure, people who had acquaintances who were PWE, those who had PWE in their family, and people who had studied medicine or worked in a medical profession.

CONCLUSION

We revealed that participants who had some experience with epilepsy had higher knowledge levels in both 2013 and 2017. This suggests that such experiences could be important for motivating people to seek appropriate and accurate knowledge about epilepsy, and could result in a reduction of stigma. Greater awareness is needed among the general public in Japan about various aspects of epilepsy.
