9 Thought Field Therapy“Thought field therapy with Callahan techniques® is a powerful therapy exerted through nature's healing system to balance the body's energy system. This therapy promotes stress management and stress relief as well as the reduction or elimination of anxiety and anxiety related problems. This includes help for weight control and weight loss, trauma or sleep difficulties, depression, addictions and the disorders associated with past trauma including nightmares and post traumatic stress disorder.” (underlines added)Roger J. Callahan, PhDRetrieved from November 17, 2006

11 NPR All Things Considered, March 29, 2006 “According to psychologist Roger Callahan, the creator of thought field therapy, major problems like depression can be cured quickly with this method. He says post-traumatic stress disorder is easily dispatched in 15 minutes, and even the most serious cases of anxiety, addiction and phobias are likewise subject to quarter-hour cures.”
12 Research on TFT? “Has any research been carried out on TFT? There have been no control (sic) studies on thesuccess of TFT”From the Thought Field Therapy Training Center of La JollaRetrieved from on November 17, 2006

15 Evidence Based Social Work “Professional judgments and behaviors should be guided by two interdependent principals:When ever possible, practice should be grounded on prior findings that demonstrate empirically…that they are likely to produce predictable, beneficial, and effective results.Every clients system, over time should be evaluated”Evidence Based Practice ManualOxford University Press2004Albert Roberts, PhDKenneth Yeager, PhD, LISW
16 Global Definition of EBP The conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients.Including BothThe best available clinical evidence from systematic researchIndividual clinical expertise-David Sackett
17 Huge Policy Implications Should policy makers support adoption of EBP?If so, which ones –When are they “Ready for Prime time”What is the standard of evidence?If so, how best can they support adoption?What are the pitfalls of a state or national policy level adoption of EBP?Impact on InnovationMisapplication of good models?-One size does not fit allWatering down of empirically based practice-danger of implementing in name onlyIdeology vs. Science- who is the judge of the science?Should we limit what we do to EBP?
18 Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomized controlled trials (Gordon C Smith, Jill P Pell, 2005)The perception that parachutes are a successful intervention is based. largely on anecdotal evidenceObservational data have shown that their use is associated with, morbidity and mortality due to both failure of the intervention and mechanical complications. In addition, “natural history" studies of free fall indicate that failure to take or deploy a parachute does not inevitably result in an adverse outcome...The effectiveness of an intervention has to be judged relative to non-intervention.Understanding the natural history of free fall is therefore imperative.If failure to use a parachute were associated with 100% mortality then any survival associated with its use might be considered evidence of effectiveness.Therefore, studies are required to calculate the balance of risks and benefits of parachute use.
19 Why Evidence-Based Practice Now? A growing body of scientific knowledgeIncreased interest in consistent application of quality servicesIncreased interest in outcomes and accountability by fundersPast missteps in spreading untested “best practices” that turned out not to be as effective as advertisedBecause they work !!
20 Problems in the Child Abuse Field in the U.S. Empirical evidence of efficacy has not been a common criteria for treatment selection in the child maltreatment field.Lack of outcome research for many commonly used interventions.Ready willingness among some to use, embrace, promote, and staunchly defend practices that have no evidence for their efficacy and questionable theoretical bases.Poor dissemination of the significant clinical outcome research that has been done.Ineffective approaches to continuing education.Poor adoption of empirically supported treatments in real world clinical settings.Disconnection between current scientific knowledge and practice in the field.

31 Common Errors When Deciding about Intervention Effectiveness Reliance solely on individual anecdotes and remembered cases.“That child made such amazing changes during treatment.”Confusing client satisfaction with clinical improvement.“The family just loved coming to therapy. Never missed a session during their 3 years of therapy. Amazing. Too bad they had to move away.”Misattribution of the cause of change.Failure to appreciate resilience and natural recovery.“The family got multiple services and wrap around care.”“With treatment her PTSD resolved in about 3 months after the rape.”Guru effect in training and treatment adoption.“I heard Dr. McDreamy is doing a level II training. And, it’s in San Diego in January!”“Those videos were just so amazing! I have got to try that.”Ben SaundersMUSC
32 What to look for in a Practice? Treatment or intervention protocol that has at least some scientific, empirical research evidence for its efficacy with its intended target problems and populations.Evidence may be based on a variety of research designs.Randomized Clinical Trial (RCT)Controlled studies without randomizationOpen trials, pre- post-, or uncontrolled studiesMultiple baseline, single case designsThe degree to which we are persuaded that the treatment is effective will vary by the quality of empirical support.Number of RCT’sReplication by researchers other than the treatment developersSampling, sample size used, comparison treatment, effect sizeVarious methods have been developed for classifying the level of empirical support enjoyed by treatment approaches.Should be useful for front-line practitioners

35 CEBC’s Definition of Evidence-Based Practice for Child Welfare Best Research EvidenceBest Clinical ExperienceConsistent with Family/ Client Values(modified from The Institute of Medicine)
36 The California Evidence-Based Clearinghouse for Child Welfare (CEBC) In 2004, the California Department of Social Services, Office of Child Abuse Prevention contracted with the Chadwick Center for Children and Families, Rady Children’s Hospital-San Diego in cooperation with the Child and Adolescent Services Research Center to create the CEBC.The CEBC was launched on 6/15/06.
37 Advisory CommitteeThe Advisory Committee is composed of 15 members drawn from a broad cross-representation of communities and organizations.There are representatives from:California Department of Social ServicesChild Welfare Departments from California CountiesChild Welfare Director’s Association (CWDA)California Child Welfare Training LeadersPublic and Private Community Partners Within the StateThe role of the Advisory Committee is to:Determine the topical areas for the CEBCEnsure the CEBC remains up-to-date with emerging evidence.Assist in disseminating the products of the CEBC.Provide feedback on the utility of the CEBC products.
38 National Scientific Panel The National Scientific Panel is composed of five core members and up to 10 selected Topical Experts.The Panel is nationally recognized as leaders in child welfare research and practice, and who are knowledgeable about what constitutes best practice/evidence-based practice.The Panel assists in identifying relevant practices and research and provide guidance on the scientific integrity of the CEBC products.
39 Scientific Rating Scale Relevance to Child Welfare Scale andRelevance to Child Welfare ScaleNext we’ll 1) discuss how the rating scales were developed, 2) review the scale criteria, and 3) describe the rating process
40 Rating Scale Development Goals:Multiple categoriesHigh standard for top ratings – Randomized Controlled TrialsClearly defined criteriaFocus on peer-reviewed research and ability to replicate programThere were several goals for the Clearinghouse rating system.First, some rating systems we examined had only one or two categories – programs were either on or off the list, with no middle ground or room for comparison. We wanted to have multiple categories so that each program we examined would fit somewhere in the scheme.We also wanted to establish a high standard for the top ratings, and decided to require randomized clinical trials in order to get the top two levels of the rating scale. More on these in just a minute.We wanted clearly defined criteria, so that program developers would understand exactly what was necessary to achieve each rating scale, and so that there was no ambiguity in how ratings were assigned.Finally, we wanted to focus on peer reviewed research and programs that were able to be replicated.
41 Gold Standard for Evidence Randomized controlled trial (RCT) –Participants are randomly assigned to either an intervention or control group. This allows the effect of the intervention to be studied in groups of people who are the same, except for the intervention being studied.Any differences seen in the groups at the end can be attributed to the difference in treatment alone, and not to bias or chance.Now, to cover some of these terms…Randomized Controlled trials or RCTs are considered by many to be the gold standard of evidence for a research study. They involve randomly assigned members of the study sample to either receive the intervention or a control treatment (often treatment as usual or usual care services).Randomizing the subjects ensures that the two groups are equal on factors that may influence the study outcomes. Randomly assigning them to groups ensures that group assignment is not biased by the assigner, even unconsciously.Having a control group ensures that the changes between the beginning and end of the study are due to the treatment – you can compare to the group that didn’t get the treatment and see what the difference is.
42 Peer-Reviewed Research Peer review – A process used to check the quality and importance of research studies. It aims to provide a wider check on the quality and interpretation of a study by having other experts in the field review the research and conclusions.Another term we use in the Clearinghouse is Peer-reviewed research.Peer review serves as a reality check on research. Many people find research confusing, especially when statistics are involved. These days, anyone can write and self-publish anything they want on the internet.The peer review process ensures that other people with knowledge and expertise have looked what the researchers have done and agree with the methods used and conclusions reached from the data. Peer review assures that any studies we include in our ratings have been held to a high standard.For example, most journals use a blinded peer-review process, in which the reviewers don’t know whose study they are reviewing and the author doesn’t know who reviewed their article. This helps to reduce bias and increase honesty.
43 Efficacy vs. Effectiveness Efficacy focuses on whether an intervention works under ideal circumstances and looks at whether the intervention has any impact at all.Effectiveness focuses on whether a treatment works when used in the real world.An effectiveness trial is done after the intervention has been shown to have a positive effect in an efficacy trial.Our final terms for today…Researchers often talk about the efficacy and effectiveness of programs. Let’s clarify these:Efficacy looks at whether the program works in a highly controlled setting, like a research lab or university-run mental health clinic. Efficacy means the program works in these ideal circumstances, but doesn’t tell us if it will work in more typical settings.That’s were effectiveness comes in. Effectiveness means that the program has been tested and works in real world settings, like an outpatient mental health clinic or community setting. Its been tested and show to work with actual clients in their natural setting, in the way that services are typically delivered.
44 Scientific Rating Scale Now on to the Scientific Rating Scale…Each program we review is rated on a scale of 1 to 6, where 1 stands for effective practice and 6 stands for concerning practice. Moving between ratings is like moving up or down a step, as shown here. A program rated a 2 is one step below a program rated 1, and so on…
45 6. Concerning PracticeIf multiple outcome studies have been conducted, the overall weight of evidence suggests the intervention has a negative effect upon clients served.and/orThere is a reasonable theoretical, clinical, empirical, or legal basis suggesting that, compared to its likely benefits, the practice constitutes a risk of harm to those receiving it.At the bottom of the scale are Concerning Practices. These are programs that actually cause harm to clients who receive it , or that have been shown by the majority of studies to have a negative effect.
46 5. Evidence Fails to Demonstrate Effect Two or more randomized, controlled outcome studies (RCT's) have found that the practice has not resulted in improved outcomes, when compared to usual care.If multiple outcome studies have been conducted, the overall weight of evidence does not support the efficacy of the practice.One step up from Concerning Practices is Level 5, in which the evidence fails to demonstrate that the program or practice has the desired effect.To get this rating, at least two RCTs have to have demonstrated that the program was no better than standard care. If there have been several studies, the majority of the studies need to show that the program doesn’t improve outcomes.
47 4. Acceptable/Emerging Practice- Effectiveness is Unknown There is no clinical or empirical evidence or theoretical basis indicating that the practice constitutes a substantial risk of harm to those receiving it, compared to its likely benefits.The practice has a book, manual, and/or other available writings that specifies the components of the practice protocol and describes how to administer it.The practice is generally accepted in clinical practice as appropriate for use with children receiving services from child welfare or related systems and their parents/caregivers.The practice lacks adequate research to empirically determine efficacy.One step up from Level 5 is Level 4, in which the program is termed Acceptable, but because it is a relatively new or emerging practice, it has not been widely studied and the program’s effectiveness is unknown.There are several requirements to achieve this rating.First, there must be no evidence or basis to believe that the program is harmful to clientsSecond, as described earlier, it has to have available written materials so that it can be replicated.
48 3. Promising Practice Same basic requirements as Level 4 plus: At least one study utilizing some form of control (e.g., untreated group, placebo group, matched wait list) has established the practice’s efficacy over the placebo, or found it to be comparable to or better than an appropriate comparison practice. The study has been reported in published, peer-reviewed literature.Outcome measures must be reliable and valid, and administered consistently and accurately across all subjects.If multiple outcome studies have been conducted, the overall weight of evidence supports the efficacy of the practice..But also add three new criteria:The outcome measures used in the studies need to be reliable and valid, which means that the tools are measuring what they are intended to measure and the measurements are accurate and stable.In addition, the measures have to be used consistently across all subjects. For example, you can’t use one measure with the intervention group, and a different measure with the control group.In addition, if there have been multiple studies, the majority show that the practice works.
49 2. Well Supported-Efficacious Practice Same basic requirements as Level 3 plus:Randomized controlled trials (RCTs): At least 2 rigorous RCTs in highly controlled settings (e.g. University laboratory) have found the practice to be superior to an appropriate comparison practice.-The RCTs have been reported in published, peer-reviewed literature.The practice has been shown to have a sustained effect at least one year beyond the end of treatment, with no evidence that the effect is lost after this time.Two additional requirements for a well-supported practice are that2 RCTs in controlled settings have shown that the practice works, and these results have been peer reviewed. Often, these studies are conducted by the program developer, so carefully oversees the studies to ensure that the intervention is delivered correctly.In addition, the positive results of the program have to least for at least one year after the end of treatment. For example, a parent education program may show improved child behavior and decreased parent stress at the end of the 16 week intervention, but are any of these improvements still there one year later?
50 1. Well supported - Effective Practice Same basic requirements as a Level 2 plus:Multiple Site Replication: At least 2 rigorous randomized controlled trials (RCTs) in different usual care or practice settings have found the practice to be superior to an appropriate comparison practice.The RCTs have been reported in published, peer-reviewed literature.The practice has been shown to have a sustained effect at least one year beyond the end of treatment, with no evidence that the effect is lost after this time.What been added is the requirement for at least 2 RCTs in real world settings to show an effect, and the studies reports have been peer reviewed.
51 Child Welfare RatingsNot every program that is evidence-based will work in a Child Welfare setting…We also examined each program’s experience and fit with Child Welfare systems and families
52 Relevance to Child Welfare Scale High:The program was designed or is commonly used to meet the needs of children, youth, young adults, and/or families receiving child welfare services.Medium:The program was designed or is commonly used to serve children, youth, young adults, and/or families who are similar to child welfare populations (i.e. in history, demographics, or presenting problems) and likely included current and former child welfare services recipients.Low:The program was designed to serve children, youth, young adults, and/or families with little apparent similarity to the child welfare services population.
53 Child Welfare Outcomes We also examined whether programs had included outcomes from the Child and Family Services Reviews in their peer-reviewed evaluations:SafetyPermanencyWell-being
