Differences in self-harm among adolescents and young adults with autism spectrum disorder: a gender-based approach

Introduction. Self-harm in children and young people with autism spectrum disorder (ASD) poses risks to their physical well-being, negatively impacts their quality of life and that of their families, and presents challenges to their integration into school and social environments. This study aimed to investigate possible differences in terms of gender between adolescents and young adults with autism admitted to the neurodevelopmental unit of ITA Argentona due to non-suicidal self-harming behaviour. Patients and methods. A sample of 50 patients with ASD, whose ages ranged from 14 to 27 years, who were treated in the ITA Argentona neurodevelopmental unit. The methodology adopted consisted of a non-causal correlational cross-sectional study, for which the Autism Diagnostic Observation Schedule, second edition, and the Autism Diagnostic Interview-Revised were administered, as well as the Inventory of Statements About Self-injury. Results. The results obtained revealed significant and positive correlations between sex and certain types of self-harm (burning, pulling hair and carving) and the motivations or functions that the participants report for engaging in non-suicidal self-harm. Conclusions. Although the study concluded that there is no substantially greater likelihood of one sex in particular engaging non-suicidal self-harm, significant differences were identified in terms of the specific types of self-harm, and the motivations or functions associated with these non-suicidal self-harming behaviours.
