Which theories are less concerned with the explanation of personality development and changing personality than they are with describing personality and predicting behavior based on that description?

Trait theory

Explanation:

Trait theory suggests that over the time the personality of any individual remains stable. Once you are in one state of your personality with one sense of thought then it is unlikely that you will change your personality for long period of time.For example: if you are an introvert kind of person from the childhood then no matter how many training you attend or counseling you get you won’t be able to express yourself among the group of people, according to the trait theory.
