It was described as a careful decision making process about the care of individual patients using best available evidence by Sackett, Rosenberg, Gary, Haynes, and Richardson (1996). Greenhalgh (2010) gave a similar definition but with more emphasis on the mathematical assessment of the potential benefit and harm. By now, EBP has been widely adopted by many health disciplines, including psychology. In 2005, the American…show more content…
Klein (2014), a research psychologist, argued in his article on Edge that EBP should be abandoned. This article will address each of the four points he made in the article. The first point Klein (2014) made was that research evidence is not always a completely reliable, and therefore shouldn’t be trusted. This is an invalid argument for several reasons. It is true that research has limitations due to a number of reasons: the nature of the research questions, funding restriction, random sampling availabilities, ethical restrictions, and limitations of statistical techniques. Science is not perfect, some studies are less reliable than others, and we will never be certain if the conclusions are true or not, but what is the better alternative? Without EBP, the clinical decisions can only be based on some novel ideas or / and clinical observations, but they are often wrong. Prefrontal lobotomy, a surgical procedural that cuts off neural connections in the prefrontal cortex, was based on a novel idea; it was thought to be effective in managing undesirable symptoms of patients with mental disorders, and it seemed to work as some patients did have reduced symptoms. However, it improved some of the patients’ symptoms but left profound long-term damage to most of the patients. Those patients had personality change, inability to function in the society, apathy, lost of initiation and inhibition (Freberg, 2010; Szasz, 2007). No research evidence will ever be completely
