AdEPT:Understanding and Preventing the Adverse Effects of Psychological Therapies

Meta-analysis of Previous Randomised Controlled Trials

Studies into the effectiveness of psychological therapy generally report how many clients have improved from receiving therapy compared to other interventions. However, they rarely report how many people experience increased symptom severity after receiving the therapy. We are, therefore, contacting researchers to ask for their data from existing studies. We plan to analyse this data to learn more about the number of people who have deteriorated after receiving therapy interventions. We will collate and combine the data from a number of studies, to explore deterioration rates in psychological therapy compared to other interventions. This will enable us to learn more about the likelihood of clients of experiencing deterioration when engaging in psychological therapy compared to having no intervention or other forms of intervention.
