-gather evidence to support/refute negative thoughts
-replace negative thoughts

51
Q

What is the third-wave CBT like?

A

-also focus on cognitions and behaviours
-instead of refuting irrational/negative thoughts, holds that nonreactive or nonjudgmental attention to emotions can reduce their power to create distress

52
Q

What are the critiques of CB Models?

A

-reduce complex behaviours to simple learning or interpretations (dismisses biology)
-doesn’t address if problematic thoughts or depression comes first
-cognitions are not observable phenomena
-authority role of therapist: power to identify irrational beliefs may be intimidating

53
Q

What is the impact of CB Models?

A

-strong evidence of its benefits in improving depression, anxiety disorders, eating disorders, and schizophrenia (long-term; unlike meds)

54
Q

What are humanistic Models?

A

-suggest that all humans strive to fulfill their potential for good (Maslow’s hierarchy of needs)

Q

What were Carl Rogers’ views?

A

-we have inherent tendency to strive toward the realization of one’s full potential
