In a research first, cognitive therapy (CT) was discovered to be instrumental in reducing the acuteness of symptoms in drug-free schizophrenia spectrum disorder patients. The study, which appeared in The Lancet, researched 74 patients with the disorder, ages 16-65 years old. The randomly selected CT group received 26 weekly sessions up to 9 months, with a maximum of four boosters in the following 9 months. Normalization, self- evaluation, behavioral experiments, and patient assistance with unhelpful responses, were all part of their therapy. The Positive and Negative Syndrome Scale (PANSS), revealed significantly fewer symptoms in the cognitive therapy group, as well as an improvement in personal and social functioning.
