Evidence-Based Practice: The Science of Clinical Psychology

The evidence-based practice model has been subject to little theoretical examination. To bridge this gap, this thesis investigates the model’s ontology, epistemology, guiding theory of scientific method, the notions of ‘best evidence’ this informs and how the model is translated in clinical practice. Doing so reveals number of limitations within the model. These include the privilege of empirical over theoretical and conceptual knowledge claims, a resultant focus on intervention research, and the failure to recognise the values-based nature of such commitments. These issues also pose a number of constraints when translated as a guide for professional practice. The Model of Clinical Enquiry (MCE) is offered as preliminary attempt to address these limitations and stimulate further theoretical development in the area. This methodologically orientated approach, highlights the different forms of knowledge and values operating throughout the clinical enquiry process, their relationship to the key stakeholders, and how they unfold across time.
