<P> Evidence - based practice (EBP) is an interdisciplinary approach to clinical practice that has been gaining ground following its formal introduction in 1992 . It started in medicine as evidence - based medicine (EBM) and spread to allied health professions, educational fields, and others . EBP is traditionally defined in terms of a "three legged stool" integrating three basic principles: (1) the best available research evidence bearing on whether and why a treatment works, (2) clinical expertise (clinical judgment and experience) to rapidly identify each patient's unique health state and diagnosis, their individual risks and benefits of potential interventions, and (3) client preferences and values . </P> <P> Evidence - based behavioral practice (EBBP) "entails making decisions about how to promote health or provide care by integrating the best available evidence with practitioner expertise and other resources, and with the characteristics, state, needs, values and preferences of those who will be affected . This is done in a manner that is compatible with the environmental and organizational context . Evidence is research findings derived from the systematic collection of data through observation and experiment and the formulation of questions and testing of hypotheses". </P>
