Social impairment refers to a broad range of social problem behaviours including difficulties in understanding social information, inability to adjust behaviour to fit in social situations, reduced social interest, and lack of meaningful relationships [11]. These impairments are prevalent in social functioning of children and adults who have ADHD, and are further aggravated in individuals who have shown aggressiveness at early age [12]. Antisocial behaviour leading to social impairment is influenced by several factors, such as genetic predisposition, parental psychopathology, socioeconomic status, neurocognitive impairment, school failure, substance abuse, and other psychiatric disorders as mediators [13].
