Wiles study- depression

• Aim

  to investigate whether treating treatment resistant people with antidepressants and CBT is more effective than just antidepressants
• Method

  469 participants from Bristol, Exeter and Glasgow with treatment resistant depression

  had been taking antidepressants for more than 6 weeks and still had symptons

  randomly assigned to a condition

  condition 1 = antidepressants only

  condition 2 = antidepressants + CBT
• Results

  after 6 months 422 participants left

  condition 1 = 21.6% had more than 50% reduction in symptoms

  condition 2 = 46.1% had more than 50% reduction in symptoms

  after 12 months 396 participants left
• Conclusion

  CBT + antidepressants are more effective than antidepressants alone
• strength

  real life application

  findings of the most effective treatment for depression can be used so more people can receive effective treatment for their symptoms to manage mental health
• weakness

  -use of self report methods decreases validity

  used questionnaires to find out severity of depression and participants could have shown social desirability (lying)

  -high drop out rate

  16% of people dropped out as it took lots of effort to target their feelings and also a lot of time for the therapy to work
