| Abstract |
Objectives: We aimed to search for aggressive behavior’s risk factor in autism spectrum disorders and to seek for the correlation between subtypes of aggression and the severity of autism. Methods: This study involved 50 children fulfilling DSM-IV and DSM 5 autistic disorder diagnosis and confirmed by the ADI-R. The severity of autism was determined using the CARS. The PEP-R was used to assess the age of development and the children's skills. The assessment of aggressiveness was done using the Behavior Problems Inventory (BPI-01), which was translated into Arabic literary and against-translated, and using a questionnaire specifying the, the diachronic evolution of aggressive behavior and allowing a functional analysis.Were excluded children with an organic pathology or a known associate genetic syndrome whose symptomatology is characterized by aggressive behavior (like LeshNyhan Syndrome or unbalanced epilepsy). Results: The sexe-ratio of our sample was 9/1 with a mean age of 6 years (SD: 2) [3-12 years]. 80% of the patient presented intellectual disability when taking into account their developmental aged on the PEP-R. The mean CARS of the sample was 37.1 (SD : 7) [20- 53].The prevalence of auto-aggressive behavior was 46% and that of hetero aggressiveness was of 60%. Multivariate analysis isolated the following risk factors for hetero aggression: the absence of the "No" (p = 0,002) and the elevated ADI-D score (p = 0,017) and for self-harm: age (p = 0,03), the high pain threshold (p = 0,005), digestive disorders (p = 0,04), and mental retardation (p = 0,004). Our sample was divided into four groups according to the type of aggression: not aggressive (20%), self-injurious only (8%), hetero aggressive only (28%), auto and hetero-aggressive (44%). The prevalence of auto-aggressive behavior was 46% and that of hetero aggressiveness was of 60%. The group of children with isolated hetero aggression had a lower score on the CARS comparing groups with both self and hetero-aggressive (p = 0.008) and non-aggressive (p = 0.02) behaviors. Conclusion:This study illustrates the importance to give in clinical practice to this symptom and invites us to analyze aggressive behavior in light of the complex set of interactions between an individual and his environment |
