Autistic individuals are at increased risk of experiencing various forms of victimization during their lifespan. This study analyses the self-reported prevalence of bullying victimization in autistic pre-adolescents and those with subthreshold autistic traits in comparison with peers without neurodevelopmental conditions. The sample was comprised of 323 participants (11 and 12 years old; 45 with autism or subthreshold autistic traits) from Spanish general education schools. The assessment protocol included psychopathological (autism characteristics and co-occurrent problems), cognitive and academic characteristics. Bullying victimization was self-reported by the pre-adolescents themselves using the Bullying and School Violence Questionnaire ( Acoso y violencia escolar). Autistic participants (57.9%) and those with subthreshold autistic traits (26.9%) showed a higher rate of bullying victimization in comparison with their peers (18.3%). Bullying rates were more frequent and severe and were characterized by intimidation and social exclusion behaviours. These problems were associated with greater intensity of restrictive and repetitive behaviours and with more co-occurring behavioural and emotional problems. We did not find any association with other individual or family factors. Our data reveal the greater risk of bullying behaviours among autistic young people and those with subthreshold autistic traits, which implies the need for detection and establishment of protocols to prevent consequences for their mental health and quality of life.

Lay abstract

Autistic individuals face a higher risk of various forms of victimization throughout their lives, with bullying being especially prevalent during their school years. Previous studies indicate that autistic children are 2.4 times more likely to be bullied than their typically developing peers and twice as vulnerable as those with other disabilities. However, the extent of this issue among Spanish schoolchildren with autism remains unexplored. In addition, there is no information regarding the presence of bullying victimization in children with marked but undiagnosed autistic traits (i.e. subthreshold autistic traits). This study examines the self-reported prevalence of bullying victimization in autistic pre-adolescents and those with subthreshold autistic traits, comparing them with peers without neurodevelopmental conditions. The study involved 323 participants (11 and 12 years old; 45 with autism or subthreshold autistic traits) from Spanish general education schools. The results revealed a higher rate of bullying victimization among autistic participants (58%; 3.1 times higher risk) and those with subthreshold autistic traits (27%; 1.5 times higher risk) compared with their peers without neurodevelopmental conditions (18.3%). Victimization was linked to more intense restrictive behaviours and increased behavioural and emotional problems. No significant associations were found with other individual or family factors. Our findings underscore the heightened risk of bullying faced by autistic pre-adolescents and those with subthreshold autistic traits at school, emphasizing the need to identify and implement preventive measures to mitigate bullying and its detrimental impact on their mental well-being and overall quality of life.
