Final answer:
The main focus of a treatment for depression that involves examining and changing negative statements is cognitive therapy. It helps to alter inaccurate thoughts and beliefs to improve emotional well-being.
Step-by-step explanation:
The process of examining a person's negative statements and encouraging the person to change them is a key component of cognitive therapy, which is a treatment for depression. Cognitive therapy focuses on identifying and modifying inaccurate or maladaptive thinking patterns, emotional responses, and behaviors.
Developed by Aaron T. Beck, cognitive therapy is particularly effective in treating depression by helping patients to recognize negative thought patterns and beliefs (cognitive distortions) and challenge and change these thoughts to more realistic and positive ones.
