Calvin was a premature baby who had a lack of oxygen during his early days in the NICU. The lack of oxygen resulted in some key changes in his brain that made him somewhat more difficult, and he is quite prone to emotional outbursts. Because of these behaviors, his parents often become frustrated and use some rather ineffective parenting strategies. The combination of his inability to self-regulate his emotion and his parents' response to that have resulted in Calvin having problems with inattention and hyperactivity. This pathway illustrates the model of disruptive behavior disorders.

This pathway illustrates what is referred to as the multifactorial or

biopsychosocial model of disruptive behavior disorder.

The multifactorial or biopsychosocial model is a model under the disruptive

behavior disorder. It depends on a variety of factors such as  biological

factors or social factor which produces a disruptive behavior  outcome which is usually associated with inattention and hyperactivity. It could be genetic, caused by stress or ineffective parenting style which triggers the symptoms.

In this scenario, Calvin was subjected to ineffective parenting style which

triggered the problems he had with inattention and hyperactivity thereby

making multifactorial or biopsychosocial model of disruptive behavior

disorder the right choice.

Multifactorial or biopsychosocial models of disruptive behavior disorders.

Explanation:

The multifactorial or biopsychosocial model of disruptive behavior disorder is one of the model of a disruptive behavior disorder or ADHD that depends on the more than one factors such as biological factors, social factor or parenting issues that produces such disruptive behavior with inattention and hyperactivity.

In this case, the pathway is majorly genetic or due to pregnancy, some largely due to stress can lead to brain and neurochemical changes, combined with ineffective parenting trigger symptoms of inattention, impulsivity, and hyperactivity .

Thus, the correct answer is Multifactorial or biopsychosocial models of disruptive behavior disorders.
