Evidence-Based Practice

This NASW Research Web Page focuses on Evidence-Based Practice. Social workers increasingly are seeking information about evidence-based practices. Numerous resources are emerging to help connect research to practice and provide information that can be helpful to practitioners. Since the term evidence-based practice (EBP) is used in numerous ways, definitions will be provided that can help expand social workers� understanding of EBP. resources, and publications will be identified that can be useful to inform practice and guide policymakers. Since the identification of evidence-based practices involves assessing the available body of practice-relevant research, having a robust social work research base is important (See also the research Web page, �Keeping Up with Research,� as well as the other pages in this Resource Section.)

In April 2007, the National Institute of Mental Health (NIMH) hosted an invitational symposium of social work leaders, representatives from federal agencies and national organizations, consumer and advocacy groups, and experts who were implementing model EBP efforts in states and at schools of social work. The report from the symposium, Partnerships to Integrate Evidence-Based Mental Health Practices into Social Work Education and Research, was prepared by the Institute for the Advancement of Social Work Research (IASWR) under contract to NIMH. Portions of this Web page are adapted from a report and the briefing paper developed by IASWR in conjunction with a symposium. The full report can be found at http://charityadvantage.com/iaswr/EvidenceBasedPracticeFinal.pdf. The symposium attendees identified a number of issues related to the incorporation of EBP into mental health practice including the following:

  • Social workers and other mental health professionals must be skilled in assessment and diagnosis so the interventions they select appropriately match the identified problem.
  • Evidence-based treatments (EBT) must be adapted and personalized for individuals based on their culture, interests, and circumstances.
  • Consumers and professionals are important stakeholders in developing research agendas so research moves from effectiveness and efficacy to intervention research and takes into account real-world issues of resources, access, consumer and organizational culture, and organizational climate.
  • Given the nature of mental illness, the prevalence of co-occurring conditions, and the wide array of settings in which treatment may be provided, incorporation of EBT must take these multiple disorders and multiple settings into account.
  • Due to the breadth of the services that social workers provide to persons with serious mental illness, knowledge of interventions must be broader than being able to implement specific evidence-based mental health psychotherapies; however, social workers working with persons with mental health disorders should also be exposed to relevant EBT.
Definitions

Evidence-Based Practice. The term evidence-based practice (EBP) was used initially in relation to medicine, but has since been adopted by many fields including education, child welfare, mental heath, and criminal justice. The Institute of Medicine (2001) defines evidence-based medicine as the �integration of best researched evidence and clinical expertise with patient values� (p. 147). In social work, most agree that EBP is a process involving creating an answerable question based on a client or organizational need, locating the best available evidence to answer the question, evaluating the quality of the evidence as well as its applicability, applying the evidence, and evaluating the effectiveness and efficiency of the solution. EBP is a process in which the practitioner combines well-researched interventions with clinical experience, ethics, client preferences, and culture to guide and inform the delivery of treatments and services.

Evidence-Based Practices, Evidence-Based Treatments, Evidence-Based Interventions, and Evidence-Informed Interventions are phrases often used interchangeably. Here, for consistency, we will use the term �evidence-based treatments� (EBT). Differentiating from the evidence-based practice process described above, one definition of an evidence-based treatment is �any practice that has been established as effective through scientific research according to a set of explicit criteria� (Drake et al., 2001). These are interventions that, when consistently applied, consistently produce improved client outcomes. Some states, government agencies, and payers have endorsed certain specific evidence-based treatments such as cognitive behavioral therapy for anxiety disorders and community assertive treatment for individuals with severe mental illness and thus expect that practitioners are prepared to provide these services. �

Evaluation of Research on Practice Interventions. Randomized controlled trials (RCT) are frequently viewed as the �gold standard� for the evaluation of interventions. However, it is not always possible or ethical to conduct RCT in social, health, and human services, and thus there is a lack of that type of research evidence for some interventions provided by social workers. Qualitative research can enhance quantitative research and help us better understand cultural issues and contexts related to interventions. �

Some view research as falling into a hierarchy with the highest level of the strength of research being systematic reviews and meta-analyses. From this perspective, the next levels of evidence from highest to lowest are: RCT; quasi-experimental studies; case-control and cohort studies; pre-experimental group studies; surveys; and qualitative studies (McNeece & Thyer, 2004). A number of organizations have attempted to develop objective evidence grading systems to rate the strength of evidence for interventions. For example, the California Evidence-Based Clearinghouse for Child Welfare (www.cachildwelfareclearinghouse.org) has developed a detailed six-level system. The Institute of Medicine (IOM) has convened a multidisciplinary roundtable on evidence-based medicine that is exploring multiple issues including examination of the lack of consistency in assessing the strength of evidence regarding what works .

The Campbell Collaboration conducts systematic reviews of research and promotes systematic reviews because such rigorous analysis of research endeavors to �minimize bias in the identification, assessment and synthesis of research results� (Littell, 2006, p. 9). In these systematic reviews, the review process and decision-making criteria are transparent and established in advance.

While there is no consistent agreement on the hierarchy of best available research, a common perspective on a hierarchy of evidence might be:

  • Surveillance data;
  • Systematic reviews of multiple intervention research studies;
  • Expert opinion/narrative reviews;
  • A single intervention research study;
  • Program evaluation;
  • Word of mouth/media/marketing; and
  • Personal experience.

For practitioners trying to identify EBT for the clients they serve, there are a growing number of Web sites and guidebooks available to provide some useful information to help guide practice. In identifying EBT, the practitioner must assess the extent to which the particular EBT is adoptable and adaptable for their client and specific situation. In particular, practitioners may have concerns that many interventions are tested on very homogenous samples and therefore may not represent the complex co-occurring conditions or cultural and community contexts of many of the clients with whom social workers work.

The University of Minnesota School of Social Work convened a group of researchers, practitioners, educators, consumers, legislators, and judges to address this issue at a symposium on Evidence-Based Practice and Cultural Competence in the Context of Child Welfare.
