A psychotherapist provides psychological treatment and therapy to mental health patients rather than medication. They commonly help patients with addiction, depression, post-traumatic stress disorder, obsessive-compulsive disorder, and a wide range of other behavioral, emotional, and social issues. Their job duties typically include talking to patients to understand their problems, assessing their emotional state, analyzing patients to ensure issues are handled effectively, developing treatment methods, and observing the patient to record progress. Some psychotherapists utilize techniques such as hypnotherapy and cognitive behavioral therapy.
