Final answer:
CBT is an effective treatment for depression, equalling medications in some cases. It is false to suggest CBT is only about using metacognition for emotion management. Treatment for depression includes a variety of approaches besides CBT, such as psychotherapy, medication, and brain stimulation techniques.
Step-by-step explanation:
Cognitive-behavioral therapy (CBT) is a widely used treatment for depression that focuses on the intersection between thoughts, feelings, and behaviors. Studies such as those by DeRubeis et al. (2005) have shown that CBT can be as effective as medications for treating moderate to severe depression, particularly when therapists take cognitive processes and behaviors into account, as depicted in FIGURE 1.16 from provided resources. However, to suggest that one should use metacognition to simply reflect on the source of emotions and manage them as a standalone treatment (apart from CBT practices) is false. CBT involves a structured program that helps patients identify and challenge distorted thoughts, believes, and behaviors that contribute to their depression.
