Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by the presence of delayed or defective development before the age of three years, as well as behavioral difficulties in social communication and interaction. To evaluate ASD knowledge and awareness, as well as ASD information sources in a sample of the Libyan general population, and to explore factors that could be associated with the knowledge and awareness. A cross-sectional study was carried out between 22 March and 13 August, 2022 using a self-administered questionnaire. The study included 2350 individual aged 18 and up from households living in different regions in Libya (eastern, southern, central, and western). Out of 2195 participants, 48.9% were females and 51.1% were males. Three-quarters of the participants (74.8%) presented a low level of knowledge about autism causes. Of those whose source of knowledge of autism was social media, 78.9% had a low level of knowledge. However, 57.9% of the participants showed a good level of awareness of autism symptoms and signs. The participants had a limited understanding of the causes and characteristics of ASD. Raising community awareness of the causes and characteristics of ASD is a priority.
