Article Excerpt
Over the past decade, there has been an increasing recognition that social work should be evidence based. The potential contribution of evidence-based practice (EBP) to the effectiveness, efficiency, and accountability of social work education and practice has been emphasized (Gambrill, 1999, 2007; Gellis & Reid, 2004; Gilgun 2005; Thyer, 2004). This article reflects on reasons, preconditions, and effects of adopting EBP in social work. These issues are important but are rarely examined. We find that the proponents of EBP in social work are conservative toward the problem that research evidence is not used by practitioners. They neglect the preconditions for implementing EBP and are not sensitive to the negative effects of adopting EBP in social work.
MEANING AND PERFORMANCE OF EBP IN SOCIAL WORK
In terms of the meaning of EBP, many scholars in social work (for example, Gambrill, 1999; Gibbs & Gambrill, 2002; Gilgun, 2005; Thyer, 2004) follow the definition of evidence-based medicine, such as "the integration of best research evidence with clinical expertise and patient values" (Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000, p. 1). Regarding the performance of EBR five steps of evidence-based medicine formulated by Sackett et al. (2000) are also followed by social work scholars (for example, Gibbs & Gambrill, 2002; Thyer, 2004). The five steps are as follows: first, to covert one's need for information into an answerable question; second, to search the best evidence to answer that question; third, to critically evaluate that evidence; fourth, to integrate the critical evaluation of research evidence with one's clinical expertise and with the patient's unique biology, values, and circumstances; and fifth, to evaluate one's own effectiveness and efficiency in undertaking the previous steps and to strive for self-improvement.
REASONS TO ADVOCATE EBP IN SOCIAL WORK
A review of literature on EBP in social work reveals two fundamental reasons for academics to advocate EBP in social work. According to Gibbs and Gambrill (2002), Rosen (2003), and Crisp (2004), one obvious reasons to advocate EBP in social work is that social workers in service agencies have seldom applied research evidence to their practice. These academics all based their arguments on studies by Kirk and Rosenblatt (1981), Rosen (1994), and Rosen, Proctor, Morrow-Howell, and Staudt (1995), in which the findings revealed that social workers rarely use and value research evidence in their decision making for interventions and other practices. Another reason is that EBP is believed to be able to promote the utilization of research findings in social work education and practice. For example, to advocate EBP in social work education, Howard, McMillen, and Pollio (2003) highlighted the importance of empirical research to effective social work practice; they argued that scientific findings should guide the selection and application of social work practice and that social workers should remain current with a growing scientific database.
DISCUSSION AND SUGGESTIONS
EBP has potential benefits to social work. First, social work has been obsessed with professional status (O'Neill, 1999). The emphasis of research evidence in EBP social work can enhance the credibility of the social work profession. Second, it has been found that social workers seldom use research evidence in practice (Rosen, 1994; Rosen et al., 1995; Sheldon & Chilvers, 2000). The emphasis of research evidence in EBP social work...
