Behavioral Alterations in Adolescents and Young Adults With Autism Spectrum Disorder in a Hospitalization Unit: An Analysis of Self-Injury.

Background: Individuals with Autism Spectrum Disorder (ASD), may present with behavioral disturbances, difficulties dealing with change, restricted interests and/or sensory disturbances. Among their characteristic behaviors are self-injurious behaviors that tend to be compulsive, unplanned, rhythmic and repetitive. The aim of this study was to investigate the relationship between self-injurious behaviors in hospitalized adolescents with ASD, depression and anxiety.

Methods: The sample included 50 patients with ASD, aged between 14 and 27 years. These patients were assessed using the Autism Diagnostic Observation Scale (ADOS-2), the Autism Diagnostic Interview-Revised (ADI-R), the Trait-State Anxiety Questionnaire, the Beck Depression Inventory (BDI), the Adolescent/Adult Sensory Profile (AASP) and the Inventory of Statements About Self-injury (ISAS).

Results: The results revealed significant and positive correlations between the level of self-injury and its dimensions: self-regulation (ρ = 0.861), sensation seeking and strength (ρ = 0.767), suicide avoidance (ρ = 0.732), revenge (ρ = 0.643), self-control (ρ = 0.700), manifestation of distress (ρ = 0.828) and blunting (ρ = 0.702).

Conclusions: There is evidence of a positive relationship between levels of self-harm and sensory defensiveness, specifically in the emotion avoidance profile.
