Evidence-based practice in psychology: perceptions of graduate students in scientist-practitioner programs

The evidence-based practice movement in psychology (EBPP) is a relatively recent initiative to improve client care by integrating the best available research evidence with clinicians' expertise in the context of patient values and preferences. As this movement gains momentum in the field of psychology, training programs will likely need to modify their curricula to include training in the process of EBPP. An online survey was conducted of clinical psychology graduate students in programs that identified themselves as having a scientist-practitioner or clinical science model (N = 1,195). Understanding of, experiences with, attitudes towards, and training in EBPP was assessed. Students had a generally favorable view of psychology's move toward EBPP. Although students reported a moderate amount of exposure to and experiences with EBPP, misunderstandings about the principles of EBPP were prevalent. Compared to students planning primarily clinical practice careers, students planning primarily clinical research careers were more favorable towards EBPP, expected EBPP to be more influential in their future careers, and were more likely to use research, but less likely to use client preferences to guide treatment planning. Recommendations for modifying training programs to promote EBPP are discussed.     

RELATIONSHIP OF EVIDENCE‐BASED PRACTICE AND TREATMENTS: A SURVEY OF COMMUNITY MENTAL HEALTH PROVIDERS

Evidence‐based treatments (EBTs) are interventions that have been proven effective through rigorous research methodologies. Evidence‐based practice (EBP), however, refers to a decision‐making process that integrates the best available research, clinician expertise, and client characteristics. This study examined community mental health service providers’ knowledge of EBP and perceived advantages, disadvantages, reasons for not implementing full EBT protocols, and attitudes toward EBTs. Qualitative examination of mental health service providers’ definitions of EBP reveals confusion between the terms EBP and EBT. Service providers indicated several advantages and disadvantages of using EBTs. Analysis suggests that many perceived EBT disadvantages would be eliminated if EBTs are implemented as part of the EBP approach, thus allowing for clinician expertise and patient characteristics to be combined with EBTs. Alternatively, distinguishing between EBP and EBT may be more confusing than useful for most community mental health practitioners, which indicates new terminology may be needed.     

Advancing the Scientific Foundation for Evidence-Based Practice in Clinical Child and Adolescent Psychology

Evidence-based practice (EBP) has become a central focus in clinical child and adolescent psychology. As originally defined, EBP in psychology is the integration of the best available research evidence, patient characteristics, and clinical expertise. Although evidence-based perspectives have garnered widespread acceptance in recent years, there has also been some confusion and disagreement about the 3-part definition of EBP, particularly the role of research. In this article, we first provide a brief review of the development of EBP in clinical child and adolescent psychology. Next, we outline the following 4 points to help clarify the understanding of EBP: (a) knowledge should not be confused with epistemic processes, (b) research on clinician and client factors is needed for EBP, (c) research on assessment is needed for EBP, and (d) the 3-part conceptualization of EBP can serve as a useful framework to guide research. Based on these principles, we put forth a slightly revised conceptualization of EBP, in which the role of research is expanded and more clearly operationalized. Finally, based on our review of the literature, we offer illustrative examples of specific directions for future research to advance the evidence base for EBP in clinical child and adolescent psychology.     

Evidence-based practice in clinical psychology: what it is, why it matters; what you need to know

The history and meaning of evidence-based practice (EBP) in the health disciplines was described to the Council of University Directors of Clinical Psychology (CUDCP) training programs. Evidence-based practice designates a process of clinical decision-making that integrates research evidence, clinical expertise, and patient preferences and characteristics. Evidence-based practice is a transdisciplinary, idiographic approach that promotes lifelong learning. Empirically supported treatments (ESTs) are an important component of EBP, but EBP cannot be reduced to ESTs. Psychologists need additional skills to act as creators, synthesizers, and consumers of research evidence, who act within their scope of clinical expertise and engage patients in shared decision-making. Training needs are identified in the areas of clinical trial methodology and reporting, systematic reviews, search strategies, measuring patient preferences, and acquisition of clinical skills to perform ESTs.     

Teaching evidence-based practice: implications for psychology

A movement advocating the use of evidence-based practice (EBP) is increasingly influencing health care and the practice of psychology. Thus, teaching evidence-based practice in psychology (EBPP) is critical to the preparation of future health service psychologists. In this article, the authors address common myths associated with EBP, propose core components involved in teaching EBPP, and describe an example of how such training can be incorporated into a professional psychology education and training curriculum.     

Making Fidelity an Intramural Game: Localizing Quality Assurance Procedures to Promote Sustainability of Evidence‐Based Practices in Usual Care

Although the science of disseminating empirically supported behavioral treatments has made remarkable advances, the ultimate goal of dissemination—sustaining the implementation of evidence‐based practices (EBPs) in usual care with a high degree of fidelity—remains challenging. This article presents a rationale and guidelines for transitioning from conventional purveyor‐driven dissemination methods to intramural quality assurance procedures that can be maintained with routine agency resources. Three innovations for localizing EBP quality assurance are described: adaptation of observational fidelity methods for therapist self‐report and supervisor observation of EBPs, process control benchmarking methods for continuous tracking of EBP fidelity strength and consistency, and development of intramural clinical expertise grounded in local management of EBP implementation and outcome data. These innovations exemplify a fundamentally empirical approach to sustaining quality EBP implementation in frontline settings.     

Why many clinical psychologists are resistant to evidence-based practice: Root causes and constructive remedies

Psychotherapists are taught that when a client expresses resistance repeatedly, they must understand and address its underlying sources. Yet proponents of evidence-based practice (EBP) have routinely ignored the root causes of many clinical psychologists' reservations concerning the use of scientific evidence to inform clinical practice. As a consequence, much of the resistance to EBP persists, potentially widening the already large scientist–practitioner gap. Following a review of survey data on psychologists' attitudes toward EBP, we examine six sources underpinning resistance toward EBP in clinical psychology and allied domains: (a) naïve realism, which can lead clinicians to conclude erroneously that client change is due to an intervention itself rather than to a host of competing explanations; (b) deep-seated misconceptions regarding human nature (e.g., mistaken beliefs regarding the causal primacy of early experiences) that can hinder the adoption of evidence-based treatments; (c) statistical misunderstandings regarding the application of group probabilities to individuals; (d) erroneous apportioning of the burden of proof on skeptics rather than proponents of untested therapies; (e) widespread mischaracterizations of what EBP entails; and (f) pragmatic, educational, and attitudinal obstacles, such as the discomfort of many practitioners with evaluating the increasingly technical psychotherapy outcome literature. We advance educational proposals for articulating the importance of EBP to the forthcoming generation of clinical practitioners and researchers, and constructive remedies for addressing clinical psychologists' objections to EBP.     

Validation of the modified Fresno Test: assessing physical therapists' evidence based practice knowledge and skills

Background  

Health care educators need valid and reliable tools to assess evidence based practice (EBP) knowledge and skills. Such instruments have yet to be developed for use among physical therapists. The Fresno Test (FT) has been validated only among general practitioners and occupational therapists and does not assess integration of research evidence with patient perspectives and clinical expertise. The purpose of this study was to develop and validate a modified FT to assess EBP knowledge and skills relevant to physical therapist (PT) practice.     

Principles for Training in Evidence‐Based Psychology: Recommendations for the Graduate Curricula in Clinical Psychology

We argue that the evidence‐based practice (EBP) model represents an evolution in integrating science and practice and synchronizes well with broader trends in health care. Because the curriculum for EBP training involves explicit emphasis on the best empirical evidence within Clinical Psychology, it can be utilized by all programs, irrespective of theoretical orientation or training mission. We articulate four principles that speak to core training and foundational clinical supervision, to guide training using an EBP model. These principles can be integrated within the larger rubric of a program and can encourage more consistent curricular reliance on EBP. This approach to doctoral training could lead to greater consistency across training programs and bring science and practice closer together within Clinical Psychology.     

Practice‐based evidence: benchmarking NHS primary care counselling services at national and local levels

There are a number of problems for evidence‐based practice (EBP) including limited generalizability of efficacy research results, the consequent lack of confidence in the relevance of such research, and the conceptual distance of most practitioners from the research process. The result is that EBP, although sound in principle, often fails to achieve its aim of improving practice. Practice‐based evidence (PBE) provides a complementary bridge for the gap between research and practice to offset some of these problems, promoting collaboration between mental health services and academic institutions. This paper presents the initial results of such a collaboration via three phases: (1) the development of a referential database for primary care counselling services, (2) ‘practitioner‐friendly’ feedback on grouped data to services, and (3) the combination of the two to build an evidence base for work with ethnic minorities—an area in which research trials are not well adapted to provide much evidence.

A survey of influences on the practice of psychotherapists and clinical psychologists in training in the UK

A questionnaire survey of 95 qualified psychotherapists of various therapeutic orientations and 69 psychologists in clinical training was carried out to investigate the main influences on their clinical practice, using the Questionnaire of Influencing Factors on Clinical Practice in Psychotherapies (QuIF‐CliPP). For the qualified group the most highly rated factors were current supervision, client characteristics, client feedback, psychological formulation, intuition/judgement, professional training and post‐qualification training. For the trainees, those rated highest were current supervision, past supervision, client characteristics, client feedback, psychological formulation and professional training. Evidence based factors such as treatment manuals and evidence based guidelines were rated relatively low for both groups, although the cognitive behaviour therapists rated them significantly higher than the other groups. Personal therapy was rated highly by the psychodynamic, psychoanalytic, person centred and eclectic therapists but not by CB therapists. The implications of these findings for the application of evidence based practice and the need to evaluated supervision, personal therapy and training are discussed.

Examination of the analytic quality of behavioral health randomized clinical trials

Adoption of evidence-based practice (EBP) policy has implications for clinicians and researchers alike. In fields that have already adopted EBP, evidence-based practice guidelines derive from systematic reviews of research evidence. Ultimately, such guidelines serve as tools used by practitioners. Systematic reviews of treatment efficacy and effectiveness reserve their strongest endorsements for treatments that are supported by high-quality randomized clinical trials (RCTs). It is unknown how well RCTs reported in behavioral science journals fare compared to quality standards set forth in fields that pioneered the evidence-based movement. We compared analytic quality features of all behavioral health RCTs (n = 73) published in three leading behavioral journals and two leading medical journals between January 2000 and July 2003. A behavioral health trial was operationalized as one employing a behavioral treatment modality to prevent or treat an acute or chronic physical disease or condition. Findings revealed areas of weakness in analytic aspects of the behavioral health RCTs reported in both sets of journals. Weaknesses were more pronounced in behavioral journals. The authors offer recommendations for improving the analytic quality of behavioral health RCTs to ensure that evidence about behavioral treatments is highly weighted in systematic reviews.     

Promoting the Internationalization of Evidence‐Based Practice: Benchmarking as a Strategy to Evaluate Culturally Transported Psychological Treatments

In addition to the growing evidence‐based practice movement in psychology, psychological treatments are undergoing increasing adaptation and transportation to other countries and cultures around the world, prompting the need to evaluate treatments in these diverse settings. This article proposes the “benchmarking” strategy as a valuable approach to evaluate the effectiveness of culturally adapted or transported treatments and to promote the internationalization of evidence‐based practice. We first describe the benchmarking concept in clinical research, followed by considerations for the cultural adaptation and transportation of psychological treatments. We then explain how the benchmarking strategy may be used to validate culturally transported and adapted psychological treatments. The article concludes with a discussion of considerations, limitations, and challenges for conducting cross‐cultural benchmarking research.     

Evidence‐based implementation practices applied to the intensive treatment of eating disorders: Summary of research and illustration of principles using a case example

Implementation of evidence‐based practices (EBPs) in intensive treatment settings poses a major challenge in the field of psychology. This is particularly true for eating disorder (ED) treatment, where multidisciplinary care is provided to a severe and complex patient population; almost no data exist concerning best practices in these settings. We summarize the research on EBP implementation science organized by existing frameworks and illustrate how these practices may be applied using a case example. We describe the recent successful implementation of EBPs in a community‐based intensive ED treatment network, which recently adapted and implemented transdiagnostic, empirically supported treatment for emotional disorders across its system of residential and day‐hospital programs. The research summary, implementation frameworks, and case example may inform future efforts to implement evidence‐based practice in intensive treatment settings.     

A process for instituting best practice in the intensive care unit

Goals of health care are patient safety and quality patient outcomes. Evidence based practice (EBP) is viewed as a tool to achieve these goals. Health care providers strive to base practice on evidence, but the literature identifies numerous challenges to implementing and sustaining EBP in nursing. An initial focus is developing an organizational culture that supports the process for nursing and EBP. An innovative strategy to promote a culture of EBP was implemented in a tertiary center with 152 critical care beds and numerous specialty units with diverse patient populations. A multi-disciplinary committee was developed with the goal to use evidence to improve the care in the critical care population. EBP projects were identified from a literature review. This innovative approach resulted in improved patient outcomes and also provided a method to educate staff on EBP. The committee members have become advocates for EBP and serve as innovators for change to incorporate evidence into decision making for patient care on their units.     

Multicultural competence and evidence-based practice in group therapy

The multicultural competence (MC) and evidence-based practice (EBP) initiatives have each generated healthy debates in the mental health field, with ample implications for clinical training and practice. Using two case illustrations, we highlight practical challenges and prospects in the intersection of MC and EBP. To facilitate complementary practice of MC and EBP, we offer strategies for the group therapist as a "local clinical scientist" to deliver culturally responsive treatments. We stress the importance of cultural adaptation of EBP models, namely, modifying evidence-based interventions that involve changes in service delivery, in the nature of the therapeutic relationship, or in components of the treatment itself to accommodate the cultural beliefs and behaviors of racial-cultural minority clients. Cultural adaptation of EBP in group therapy needs to be grounded in developmental contextualism and social justice. We discuss the two cases with an eye toward advancing multicultural competence in group therapy.     

Cognitive behaviour therapy for schizophrenia -- a review of development, evidence and implementation

BACKGROUND: Schizophrenia and other psychotic disorders were once thought to be impervious to psychological treatments; however, there is accumulating evidence that cognitive behaviour therapy (CBT) can result in significant clinical benefit to these patients. AIM: This paper aims to describe the development and adaptation of CBT in the treatment of schizophrenia, to summarise the evidence to support CBT as a viable treatment and to outline some of the issues in 'rolling out' this treatment into normal clinical settings. RESULTS: A number of clinical models of CBT have been developed and these typically consist of a variety of clinical methods with different models providing differing emphasis. Twenty controlled trials of CBT in schizophrenia in which 739 patients were included are reviewed. These studies have a mean effect size for CBT of 0.37 (SD 0.39). There is consistent evidence that CBT reduces persistent positive symptoms in chronic patients and may have modest effects in speeding recovery in acutely ill patients. The evidence of CBT reducing relapse rates is equivocal, although targeted early intervention is promising. The available evidence suggests that CBT can be utilised effectively in routine clinical practice. However, the dissemination of novel psychological treatments into widespread clinical practice is not without difficulty, and issues pertaining to the 'roll-out' of CBT are discussed. CONCLUSIONS: CBT as an adjunct treatment shows considerable promise for the future treatment of schizophrenia.     

Training Therapists in Evidence-Based Practice: A Critical Review of Studies From a Systems-Contextual Perspective

[Clin Psychol Sci Prac 17: 1–30, 2010]
Evidence-based practice (EBP), a preferred psychological treatment approach, requires training of community providers. The systems-contextual (SC) perspective, a model for dissemination and implementation efforts, underscores the importance of the therapist, client, and organizational variables that influence training and consequent therapist uptake and adoption of EBP. This review critiques the extant research on training in EBP from an SC perspective. Findings suggest that therapist knowledge improves and attitudinal change occurs following training. However, change in therapist behaviors (e.g., adherence, competence, and skill) and client outcomes only occurs when training interventions address each level of the SC model and include active learning. Limitations as well as areas for future research are discussed.
