At ISTDP-UK we believe in having informed practitioners striving to provide the highest quality ISTDP methods available. This supports patients to achieve the best outcomes in the shortest time for their wellbeing and long-term happiness. ISTDP is an evidence-based approach for a range of emotional and mental health difficulties (e.g. somatoform disorders, treatment resistant depression, anxiety and personality disorder).
The effectiveness of therapy is evaluated through research that is aimed to address various important questions: Does the approach help to solve particular target problems (e.g. depression) following therapy and is this sustained in the long-term after treatment? Is the approach comparable, superior or inferior to other treatment options? Is the approach cost-effective by reducing costs associated with the target problem at a reasonable cost of delivering the therapy?
Research explores these questions using a range of methods. The National Institute for Health and Care Excellence identified different methods as having different levels of importance for evaluating treatment effectiveness. For more information, click here. Research into ISTDP includes different research methodologies that are listed in NICE guidelines for reviewing and grading evidence (reviews, random control trials, case series data and individual case studies). ISTDP research also covers a range of target problems, in different health settings across a diverse group of countries. Please see below a list of references of some ISTDP research for different levels of evidence described above. We would especially like to thank Allan Abbass and his colleagues for their summaries of the research that enable us to provide the list below.
