Evaluating Outcomes – Group designs – Single subject designs Overview of Evidence-Based Practice Definition of Evidence-Based Practice “Placing the client’s benefits first, evidencebased practitioners adopt a process of lifelong learning that involves continually posing specific questions of direct practical importance to clients, searching objectively and efficiently for the current best evidence relative to each question, and taking appropriate action guided by evidence” (Gibbs, 2003, p 6). EBP Model Clinical state and circumstances Practitioner's Expertise Client Preferences and actions Research Evidence Haynes, Devereaux, and Guyatt, 2002 Steps of EBP* Step 1: Convert an information need into an answerable practice question. Step 2: Efficiently locate the best evidence to answer the question. Step 3: Critically appraise the evidence for its validity and usefulness. Steps of EBP (cont.)* Step 4: Using practice expertise to integrate evidence with student characteristics and school context, apply the results of the evidence appraisal to practice. Step 5: Evaluate the outcome of evidence-based action. Step 6: Teach others: challenges and obstacles *Based on Sackett, et al., 1997, and Gibbs, 2003 Range of Practice Questions Effectiveness/Prevention Assessment/Risk Descriptive Terminology Evidence-Based Practice (EBP) Evidence-Informed Practice Empirically-Supported Interventions/Treatments Resources for Learning EBP Skills Gibbs, L.

Evidence-Based Practice in School Social Work EBP in Response to Intervention and Positive Behavior Support Models Efficient and Reliable Assessment Tools/Procedures – Screening to identify prevalence of problems – Diagnostic evaluation of individual students – Monitoring of treatment fidelity and student progress Empirically-Supported Interventions – Primary Tier: core curriculum to all students/ preventive – Secondary Tier: additional support to at-risk students – Tertiary Tier: intensive support to individual students Evidence-Informed School Social Work Practice Recent survey of over 1600 school social workers indicates – Few use online databases, journals, or scholarly books to inform practice. – Primary focus on interventions targeting individual change and risk factors rather than primary prevention.

COPES Questions Client-Oriented Practical Evidence-Search Four Features of a Well-Built Question Client Type and Problem: What You Might Do: Alternate Course of Action: What You Want to Accomplish: How would I describe a group of clients of similar type? Apply a treatment; act to prevent a problem; survey or interview clients; measure to assess a problem; screen clients to assess risk. What is the main alternative other than in the box to the left, if any? Outcome of treatment or prevention; accurate description of client; valid measure; accurate risk estimation. Gibbs (2003) Research Question COPES Question Identifies specific sample Describes type of client and problem Identifies particular instance of intervention, including what, where, when, how May describe particular type(s) of interventions or ask about “best intervention” Identifies specific measurement instruments Describes intended outcomes, not measures Formulating Effectiveness/ Prevention Questions: a) Comparing an intervention to no intervention b) Comparing two interventions c) What is the best intervention? Examples Client/Problem Action Alternate Outcome Rick Ager’s question: If African American adolescents receive Motivational Interviewing or no intervention are the former more likely to decrease their use of alcohol and other drugs? Loretta Pyles’ question: For clients of social service agencies do hierarchical or collectively models of agency structured management management models Lynn Pearlmutter’s question: For couples who have experienced one partner’s marital affair what is the best therapeutic approach result in greater client empowerment? to rebuild trust? Formulating Assessment/Risk Questions: a) Comparing an assessment instrument/procedure to no assessment b) Comparing two assessment instruments/procedures c) What is the best assessment instrument/procedure? Examples Client/Problem Action Alternate Outcome Loretta Pyles’ question: Among battered women will the Danger Assessment Scale as opposed to no assessment accurately predict lethality? Judy Lewis’ question In an urban community devastated by a natural disaster does door-todoor contact with residents or outreach to existing institutions in the area a better means of predicting the potential viability of a given community? Eileen Ihrig’s’ question: For children in cross-cultural settings what is the best assessment tool? to assess psychosocial wellbeing? Formulating Descriptive (Quantitative) Questions: a) Summarizing characteristics (how much, how many, what percentage, what is the average?) b) Asking about relationships between variables Examples Client/Problem Action Cyleste Collins’ question [If] social work students [are surveyed] Rick Ager’s question [If] people who have been affected by a natural disaster [are surveyed] Alternate __________ __________ Outcome what percentage endorse stereotypical attitudes about victims of domestic violence? do they report increased alcohol and other drug use compared to predisaster levels? Formulating Descriptive (Qualitative) Questions: a) Require narrative responses b) Suggest in-depth explorations, little known phenomena (how would they describe, what is the process, how do they experience?) Examples Client/Problem Action Loretta Pyles’ question: [If] women who have been battered [are interviewed in depth] Eileen Ihrig’s question: If children in conflict situations who were abducted and became soldiers [are interviewed in depth] Alternate __________ __________ Outcome how do they describe what safety means to them? how do they describe their experiences of reintegrating into the community?

(Removing MOLES is last resort.) Too many hits: Narrow search, more specific terms, add categories, check Boolean structure.

Step 4: Applying the Evidence to Practice Application to Practice Applicability to client and practice context No evidence is an answer – role of theory, informed consent Practice wisdom – integrating art and science, experience, relationship, intuition, and evidence Application to Specific Clients and Agency Contexts (Slide from Jim Barber, based on Sackett, et al., 2000) Application Questions Decision Aids & Prompts 1. Is this case so different from those in the literature that you cannot apply their results? Differences can be of: Degree (quantitative) and/or Type (qualitative) 2. Is the intervention feasible in our setting? Potential obstacles include: Agency policy, ethics or mandate Cost (including time) Agency skill 3. What are the potential benefits and harms to our client? Taking account of cost, ‘outcome valence’ and NNT/H: Weigh the seriousness if you do Weigh the seriousness if you don’t 4. What are our client’s values & expectations for both the outcome we are trying to achieve and the intervention we are offering? Assist the client to weigh the intervention’s: Acceptability Desirability 5. Taking account of the above, does the intervention need to be modified? Modifications can be of: Degree (length or intensity) Type Step 5: Teaching Others Challenges and Obstacles Misconceptions about EBP Agency/colleague support Availability of databases/articles Potential consequences of knowledge References Gibbs, L.
