Why Study Implementation?

“Multiple studies across differing treatments found that training (workshop, manual, and supervision) was not enough to produce proficient change in therapist adherence, competence, and skill. In turn, Therapists were not necessarily able to engender client change.”

Source: Biedas and Kendall (2010). Training Therapists in Evidence-Based Practice: A Critical Review of Studies From a Systems-Contextual Perspective. Clinical Psychology Science and Practice 17, 1-30.

Page 4: Modeling Waiting List Reduction Strategies Using …...Discrete Choice Conjoint Experiments Goals of the Talk Brief Introduction to Preference Modelling Discrete Choice Experiments

For treatments to be effective and sustained in practice settings, treatment developers should consider design features that increase the appeal to the therapists who are ultimately responsible for using them.

Assume you are considering changing your teaching practice to improve the behavioral and emotional outcomes of students:

Click below the practice change strategy you would prefer:

Next

Strategy 1 Strategy 2 Strategy 3

Learning requires 2 days

My colleagues endorse this 67%

Other schools say this strategy works

Learning requires 1 day

My colleagues endorse this 100%

This strategy is promising but

unproven

Learning requires 3 days

My colleagues endorse this 33%

Research says this strategy works

Note: 999 versions – 1 randomly assigned to each participant

Partial Profile Designs

Reduce Effect of Dominant Attributes

Reduce Response Error

Reduce Total Design Error

Produce Similar Utility Coefficients

Improve Predictive Validity of Simulations

(Reduce MAE)

Why Use Discrete Choice Experiments?

Approximate Complexity of Real World Choices

Each Level Experimentally Manipulated

Each Attribute in the Context of Others

Complexity Activates Decision Making Heuristics

Users Inform Implementation Planning Tradeoffs

Reduce Influence of Social Desirability Biases

What Attitudes Distinguish Change Ready vs Demand Sensitive Segments?

Change Ready Educators:

Anticipate More Benefits to Practice Change

Find the Social Context to be More Influential

Report Higher Change Self Efficacy

More Intent on Participating

Selected Implications

Segments with Different KT Design Preferences

Change Ready versus Demand Sensitive

Outcome Sensitive vs Process Sensitive vs Demand Sensitive

Accelerated Adopters vs Gradual Adopters

Different Pattern of Preferences Across Professional Groups

Social Context Exerts More Influence Than Evidence Base

Administrators, Supervisors, Principals

Colleagues

Unions

Most Prefer Learning in a Small Group (N=10 Social Context)

An Engaging Expert Facilitator Important

Interest in Internet Options Varies Across Professional Groups

Highest in Mental Health Professionals in Accelerated Adopters Segment
