Aggression is a very common problem in many children and one which, if not addressed early enough, would continue throughout adolescence and later in life. Aggression can be caused by a multitude of factors, which are sometimes considered part of a normal stage of development; however, aggression can also be a symptom of a multitude of disruptive behaviors (Barzman & Findling, 2008). It is important for parents to learn to deal with this type of behavior and find ways to effectively modify the child's bad behavior; according to Barzman & Findling (2008) the complexity of aggression must be addressed through complex assessment strategies. Aggression has been linked to significant impacts in academic and social functioning (Farmer et al., 2011); and youth studies concluded that physical aggression was a predictive factor that preceded risky behaviors that later developed in the adolescents studied. These risky inclinations included early initiation of sexual activity and tendency toward unsafe sexual behaviors, as well as substance abuse that included tobacco, alcohol, and drugs (Deater-Decard, 2008). This is an indication of how important it is to prevent and intervene before aggression can lead to other dangerous and risky behaviors. For Deater-Decard (2008) it is essential to continue to understand and improve our ability to decrease aggression and minimize the impact on our society. Aggression is commonly linked to other disruptive behaviors such as ADHD, conduct disorder, and oppositional defiant disorder. ; in these cases it is essential to identify the primary diagnosis to develop a disorder-oriented approach that can help control aggression (List & Barzman, 2010).
