Psychotherapy Evaluation and Research Lab at Sheffield (PEARLS)
PEARLS brings together a group of academics, clinicians, research fellows and postgraduate students whose research focuses on the evaluation of routinely delivered psychological interventions.
Taking a pragmatic approach, the Lab’s mission is to better understand and then improve the effects of psychological therapies delivered in routine healthcare settings.
Collectively, our expertise and interests are in the analysis of practice-based datasets and pragmatic trials carried out in clinical settings, to understand how therapy works in routine care, and why clinical outcomes vary across services, therapy models, therapists and patients.
What we do
In order to fulfil our mission to improve routine psychological care through the development of practice-based evidence, we
conduct pragmatic trials of psychological therapies in the National Health Service
deliver practice-based evidence through analyses of routinely collected data from services
adapt existing interventions for maximum effect in routine services
generate materials to support psychological therapists in their work (such as therapy manuals and competency measures)
undertake selective research consultancy focusing on the analyses of large data sets
host research seminars and academic visits from partner Universities and clinical services
offer research internships and postdoctoral positions.
