How to the three criteria of defining psychological problems are used? and give examples?

The first problem is that a mental health professional must first decide exactly how to define "disorder." How do you determine if there is something psychologically wrong or unhealthy about a person? How do you decide what's normal and what's abnormal?

If you were to define disorder as something that lies outside of the statistical norm, then people who are considered exceptionally talented or gifted in a particular area would be regarded as abnormal. So rather than focus on actions that are considered outside of the normal statistically speaking, psychologists tend to concentrate on the results of those behaviors.

Behaviors that are considered maladaptive and cause significant personal distress and interrupt daily functioning are more likely to be labeled as disorders.
