According to Comer (2014), an individual is diagnosed with obsessive-compulsive disorder when obsessions, compulsions, or both are unreasonable or excessive, impair daily functions, cause clinically significant distress, and take up much time (p. 127). A person I know of suffers from obsessive-compulsive disorder. If anything is out of place it causes him distress, he has a certain schedule of things and becomes anxious if someone tries to change it, he won 't ride on subways or buses and does not like being around anyone who is sick because of all the germs. He also has a checking compulsion where he checks house and car door locks, makes sure his phone and wallet, and the contents of it, are where they should be at a given time, picking them up and counting multiple times before he is satisfied.
Psychologists from the biological model would say that research shows that biological factors play a key role in this person 's problem. The main factors that are probably affecting him are abnormal functioning by specific regions of the brain and low activity of the neurotransmitter serotonin.

If either of these regions in his brain are too active, this may lead to a constant eruption of troublesome actions and thoughts (Comer, 2014, p. 132). Researchers have also found that antidepressant drugs that increase serotonin activity, are the only antidepressants that help reduce obsessive and compulsive symptoms, thus his disorder might be caused by low serotonin ac...

In conclusion, there are similarities and differences between the way psychologists from each of the six theoretical models explain psychological disorders. They all present valid points, as to how this person 's problem could be explained. Combining information from each of these models creates a good overall explanation of this person 's psychological problem.
