Chapter Overview • Definitions from Medicine • The three-legged stool analogy • Defining evidence-based practice in ABA • Using evidence-based practice in ABA • Case studies in EBP in ABA

Definitions from Medicine

Definitions from Medicine • Evidence-based practice (EBP) is a term utilized in many different contexts • There is disagreement within behavior analysis and other disciplines regarding the definition of EBP • Wilczynski (2017) provides a book length analysis of this topic

Definitions from Medicine • Medicine – Sacket et al. , (1996) • Conscientious, explicit, judicious use of current best evidence in making decisions about the care of the individual • Behaviors related conscientious, explicit, and judicious use of evidence might interfere with balancing client values and professional values

Definitions from Medicine • Medicine – Strauss, et al. , (2011) • Integration of the best research evidence with our clinical expertise and our patient’s unique value and circumstances • Emphasizes a process to integrate research evidence, professional expertise, and client characteristics

Defining Evidence-Based Practice in ABA

Defining EBP in ABA • Smith (2013) • “ … an evidence-based practice is a service that helps to solve a consumer’s problem. Thus, it is likely to be an integrated package of procedures, operationalized in a manual, and validated in studies of socially meaningful outcomes, usually with group designs” (page 27). • PECS and UCLA model are examples of manualized programs, but they do not have the level of evidence (i. e. , group design research with socially meaningful outcomes) suggested by Smith as needed to be considered evidence-based practice

Defining EBP in ABA • Slocum et al. , (2014; also see Wilczynski, 2017) • Critiqued Smith (2013) as an incomplete definition of EBP • Suggested Smith’s definition aligned with definitions of evidence supported treatments • An intervention that has been shown through research to be effective with a given population (APA Presidential. Task Force, 2006)

Defining EBP in ABA • Slocum et al. , (2014; also see Wilczynski, 2017) • Evidence-based practice of applied behavior analysis is a decision-making process that integrates (a) the best available evidence with (b) clinical expertise and (c) client values and context • This definition aligns with medicine and psychology • This definition highlights the importance of EBP as a process

Using Evidence-Based Practice in ABA

Using EBP in ABA

Using EBP in ABA • Identifying the best available evidence • How do you find evidence-supported treatments? • Search for strategies based upon the identified clinical presentation (e. g. , pica, selfinjury) • This search strategy helps identify strategies specific to the problem at hand

Using EBP in ABA • Identifying the best available evidence • How do you maintain regular contact with the research literature? • Creating opportunities to read research literature can reduce the need to search for strategies when faced with novel clinical presentations • Subscribe to journals, regularly visit the websites of journals, subscribe to receive journal publication alerts, or create and attend journal reading groups with professional organizations

Using EBP in ABA • Identifying the best available evidence • How do can organizations support the process of evidence identification? • Might purchase organizational access to journals or literature databases • Provide opportunities for clinical reviews • Provide opportunities for professional development (e. g. , journal reading group, conference attendance, workshop) • Organizational systems can be evaluated to determine effect upon employee identification of evidence

Using EBP in ABA • Evaluating the available evidence once located • Not all evidence is equal • Researcher – a search of the evidence may fail to yield relevant results, or only identify weak results. The practitioner might need to function as a researcher to identify a strategy that best solves the clinical problem at hand. • Follow the core dimensions of ABA (Baer, Wolf, & Risley, 1968)

Using EBP in ABA • Evaluating the available evidence once located • Not all evidence is equal • Synthesizer – literature searches often yield multiple strategies of varying quality. Synthesizing the information is necessary. • Use personal guidelines to synthesize (e. g. , Quigley, Peterson, Frieder, & Peck, 2017) • Use published guidelines to synthesize (e. g. , National Autism Center, 2009, 2015)

Using EBP in ABA • Evaluating the available evidence once located • Not all evidence is equal • User – Sometimes the identified literature aligns closely with the clinical presentation. The practitioner can function as a user. That is, implement the strategy in a manner parallel to the publication

Using EBP in ABA • Integrating evidence with client considerations • Consider and discuss cultural variables with families • There is sparse behavior analytic literature regarding how cultural variables (e. g. , language, religion) impact treatment. Nevertheless, awareness and incorporation of cultural variables seems likely to improve intervention outcomes

Using EBP in ABA • Integrating evidence with client considerations • Verbally describe different options and possible outcomes and allow the family to choose • Utilize procedures that do not rely on vocal verbal behavior (Hanley et al. , 2005) • Assessment of strengths and weaknesses can increase client considerations

Using EBP in ABA • Integrating evidence with professional expertise • Practitioners must practice within their scope of practice and competence • One’s competence within a defined scope of practice is different from other practitioner’s competence within the same defined scope of practice • Practitioners must determine if the clinical presentation is within their scope of competence

Case Studies of Evidence-Based Practice in ABA

Case Studies of EBP in ABA • Briar • The practitioner, Cedar, failed to follow an EBP process • Cedar identified an evidence-supported treatment through a brief literature review. He did not incorporate client characteristics. Cedar lacked experience in supporting an individual with this clinical presentation

Case Studies of EBP in ABA • Andrew • Christine, the practitioner, identified a strategy from a review already conducted. She did not consider the client preferences for visual technology, nor the teacher’s skill set for implementing the strategy.

Case Studies of EBP in ABA • Vocational training • Marissa designed a strategy based upon a synthesis of existing literature. The program was informed by client preferences and values. She monitored the effects of the strategy to better incorporate client preferences and values. Marissa also had experience developing and implementing strategies with the population.
