Reading books is more effective than pills or therapy when it comes to treating mental disorders, especially depression, according to a study published in Plos One. The research studied a sample of 281 patients in the UK with mild symptoms divided into two groups. The first group were given a self-help book that followed the cognitive behavioural therapy (CBT) approach, while the second group underwent a series of traditional therapies based on therapy sessions and antidepressants. After four months, the group that read the CBT guide showed greater signs of improvement. CBT concentrates the patient on the present, rather than analysing and re-living memories and childhood traumas. The therapy helps to identify and modify thought disorders and irrational mental patterns.
