Which of the following statements best captures a key principle of Rational Emotive Therapy?

The key principle of Rational Emotive Therapy (RET) is that emotional disturbances stem from irrational beliefs. RET, developed by Albert Ellis, emphasizes that it is not the events themselves that disturb individuals, but rather the beliefs about those events. When people hold irrational beliefs, such as unrealistic expectations or negative self-talk, these beliefs can lead to negative emotions and behaviors. By identifying and challenging these irrational beliefs, individuals can change their emotional responses and improve their psychological well-being.

This understanding of the connection between thought processes and emotional reactions is foundational to RET, making the statement about emotional disturbances stemming from irrational beliefs the most accurate representation of its core principles.
