Psychotherapy and two schools of psychotherapy

Consider a broad problem area which is treated with psychotherapy and consider two schools of psychotherapy / approaches to treat that problem (CBT, DBT, Schema Therapy, or ACT).
In a brief essay address the following:
• How each therapy formulates or explain the problem and how it accounts for the change process.
• Describe the specific techniques and processes employed in each approach. • Describe what the two approaches may have in common to address the problem.
• Consider what is unique to each approach, what is distinctive and consider whether it matters.
If choosing a different problem or combination than the following please be sure to first discuss this with your learning facilitator:. CBT and DBT for Borderline Personality Disorder; or Schema Therapy or CBT and ACT for Major Depression.
