Final answer:
The purpose of teaching about the negative triad in CBT is to identify and challenge negative thought patterns, aiding in the treatment of depression.
Step-by-step explanation:
In Cognitive Behavioral Therapy (CBT), the purpose of teaching the client about the negative triad is to identify and challenge negative thought patterns. This central concept in CBT pertains to the pattern of negative views that individuals with depression may have about themselves, their experiences, and the future. Teaching clients about the negative triad is crucial as it helps them recognize these destructive thought patterns. Once identified, CBT works to challenge and alter these thoughts to more balanced and constructive ones, thereby helping to alleviate depressive symptoms and foster better mental health.
