A cross-sectional study of public knowledge and stigma towards autism spectrum disorder in Lebanon

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that requires public understanding to foster acceptance and reduce stigma. This study aimed to evaluate ASD knowledge and stigma among the Lebanese population and the factors influencing them. An online cross-sectional study was conducted between February and July 2022 among Lebanese adults. Participants completed a self-administered structured questionnaire that comprised a sociodemographic section and two validated scales serving the study’s purpose (The Autism Stigma and Knowledge Questionnaire (ASK-Q) and The Autism Social Distance Scale). A total of 949 participants filled out the questionnaire. More than half of them had adequate knowledge of autism diagnosis and symptoms (57.9%), while only 6.6% and 9.6% showed adequate knowledge of its etiology and treatment, respectively. Additionally, 83.4% of the participants did not endorse stigma toward autism. The multivariate analysis taking the knowledge total score and subscales as the dependent variables showed that declaring prior knowledge of autism was significantly associated with better knowledge (Beta = 1.38) and higher stigma (Beta = 0.26). Furthermore, a higher knowledge score (Beta = − 0.06) and a declared prior knowledge of autism (Beta = − 0.62) were significantly associated with lower autism social distance. These findings highlight the need for targeted awareness campaigns to address knowledge gaps and further reduce stigma in Lebanon.
