Cognitive Behaviour Therapy (CBT) is a type of goal-oriented psychotherapy aimed at changing maladaptive patterns of thoughts, feelings and behaviour. It adopts a problem-focused approach to resolve mental distress. CBT has been widely researched and is found useful in anxiety disorders, depression, psychosis, marital issues, relationship issues etc.  CBT is used regularly in combination with other therapeutic practices such as IPSRT, psychoanalysis, DBT, humanistic or experiential therapy. All forms of psychotherapy are often used in combination with medication. CBT has proved its versatility by tending to a range of psychological disorders such as anxiety, depression, OCD, body dysmorphia, eating disorders. CBT can also be used for non-clinical issues, for e.g., addiction, gambling, etc. Unlike medication, CBT will need active and willing participation and effort from the client’s side for it to produce long-term effects. CBT is widely accepted and used by psychologist all over the world and has more than desirable effectiveness rates. It is more effective for certain disorders than it is for others and that is due to the nature of manifestation and individual’s internal and external factors.
