Evidence-based practice in psychology

This chapter criticises the claim that evidence-based practice in psychology is a tripartite concept. While it was launched as a tripartite ideal, it fails to fulfil this ambition in practice. On closer scrutiny, the policy statement merely consists of the part best available research evidence. The two remaining parts, clinical expertise and the patient’s culture, characteristics, and preferences, are treated as scientific subcategories. The chapter analyses how this conflation has come about and why it must be solved. It provides arguments for why evidence-based practice in psychology should be a tripartite model and not a unipartite model which it currently is.
