Aims: Today, people often prefer electronic communication over traditional methods. In fact, the post-COVID-19 era has seen an increase in health consciousness, leading individuals to share various types of health information online, extending beyond their immediate acquaintances. Therefore, this research aimed to investigate the impact of health literacy on electronic word of mouth among Malaysian internet users in disseminating health information, with a focus on socio-demographic comparisons.
Instrument & Methods: This cross-sectional descriptive study involved 400 respondents, utilizing proportionate quota sampling as the sampling technique. A total of 100 samples were collected from each region of Peninsular Malaysia (Central, Southern, Northern, and East Coast), who completed a self-administered questionnaire consisting of 56 items. This instrument was adapted from a well-established Electronic Word of Mouth Questionnaire and the New Short-Form Health Literacy Instrument.
Findings: The three domains of health literacy explained electronic word of mouth effectively among respondents who were male, aged 41 to 50 years, with secondary education, and self-employed. However, stronger influences of health literacy domains on electronic word of mouth were observed among respondents who were female, aged 18 to 30 years, had a bachelor’s degree, and were currently not employed.
Conclusion: Gender, age, highest education, and occupation are influential factors of health literacy.
