Which approach assumes that disorders come from illogical, irrational cognitions, and that changing the thinking patterns to more rational, logical ones will relieve the symptoms of the disorder?

the cognitive behavioral approach.

Explanation:

The cognitive behavioral approach assumes that psychological disorders have irrational roots and changing those patterns of thinking/ those systems of belief can relieve a person's symptoms.

This approach focuses on tackling the problem at hand, the current problem the person is facing and deconstructing with them why it's irrational and what can be done about the present.

This is considered a short-term form of therapy and it's concentrated on bringing objectivity into the subjective reality of an individual.
