CBT

• Cognitive-behaviour therapy (CBT) is used in the treatment of depression as it works by challenging irrational thoughts and replacing them with more effective, rational ones. CBT is a combination of cognitive and behavioural therapy and focuses on changing maladaptive thoughts and beliefs which then change behaviour that we display in response to these thoughts and beliefs
• In support of CBT, Ellis claimed a 90% success rate for rational emotive behavioural therapy (REBT), taking an average of 27 sessions to complete the treatment
• Turner (2014) also suggests that the principles of CBT should be used more often by sports teams. In particular, the 'must win' attitude should be challenged as rational thinking after a negative event leads to mental healthiness and success. This type of therapy therefore has benefits beyond the treatment of depression. 
• Smith and Glass (1977) found that REBT was the second most successful therapy. Additionally, Butler and Beck (2000) combined 14 different meta-analysis which looked into the effectiveness of CBT, and they found that, on average, 80% of adults benefited from CBT as treatment for depression as it was more successful than drug therapy and had a lower relapse rate
• Babyak (2000) studied behavioural activation in action to see the effectiveness of the treatments on people with depression. They had 3 conditions: one group took SSRI’s, another did aerobic exercise, and the others did a combination of both. All groups showed significant improvements which indicated that CBT was at least as effective/on a similar level of improvement as drugs. They did also find that exercise however did lower the rates of relapse
• March (2007) studied the effects of SSRI’s vs CBT. They found that SSRIs had a higher effectiveness rate at 12 weeks, however at 36 weeks SSRI’s and CBT both had an effectiveness level of 81%. They did however find that a combination of SSRI’s and CBT was more effective at 12 weeks and 36 weeks with an effectiveness rate of 86% by week 36. They did find that CBT had a very significant reduction on the suicidal behaviours of patents which went from 30% to 6%.
• This indicates that CBT is at its most effective at treating depression when paired with drug treatment to supply the most support possible to patents suffering with depression.
