Research

Here at Think:Kids, we are dedicated to studying everything we do in order to guide refinements to the Collaborative Problem Solving® (CPS) approach and training methods. Our program partners with the Laboratory of Youth Behavior in the Department of Psychiatry at Massachusetts General Hospital on all research and evaluation activities. We put these resources to work every day to help us study and refine CPS.

Massachusetts General Hospital is consistently ranked by U.S. News and World Reports as one of the top five hospitals in the nation. MGH also has the largest hospital-based research program in the country.

Our Research Philosophy

At Think:Kids, we believe that there are many ways we can better understand and improve Collaborative Problem Solving® (CPS), including the use of rapid-cycle quality improvement studies, outcome evaluations, observational studies, randomized clinical trials, and implementation science. Each of these tells us something different, and together they provide a complete picture that informs our work.

Whether you are here to learn about studies that have already been completed or because you are hoping to start a research study of your own on CPS, we think you will find the information on this page useful.

How can I conduct research or evaluation on CPS at my organization?

If you are looking to evaluate the impact of CPS at your organization:

As part of organization-wide implementation of CPS, Think:Kids will fully support your organization in evaluating the impact of the approach. We will help you identify key areas of impact, select measures, plan data collection, and analyze results, providing you with annual reports to guide decision-making. For more information on organization-wide implementation, contact us.

If you are looking to conduct academic research:

We regularly collaborate with academics and service providers to answer important, generalizable questions about Collaborative Problem Solving®. If you are a student, faculty, or service provider with a research idea, or with a desire to collaborate, email the research team.

If your organization is learning CPS but is not currently engaged with us in an organization-wide implementation plan, we recommend this resource for planning your evaluation of impact.

Is CPS an evidence-based practice (EBP)?

CPS is listed on the Blue Menu of Evidence-Based Psychosocial Interventions for Youth from the PracticeWise Evidence-Based Services Database, and on the California Evidence-Based Clearinghouse for Child Welfare.

Has there been a Randomized Controlled Trial (RCT) on CPS?

Yes, this RCT was the first RCT on CPS. This study compared Collaborative Problem Solving to a common parenting approach called Parent Management Training (PMT). Children who learned CPS had significant improvements in many areas of functioning at the end of treatment and four months later. These improvements were equal to, or better than, the improvements for children who received PMT.

What types of benefits can we expect if we use CPS?

Research tells us that CPS benefits depend on who is being studied and in what context. Some benefits in school settings have included improved child behaviorreductions in teacher stress, and decreases in restrictive disciplinary practices. In clinical settings, some benefits have included reductions in restraint/seclusion and self-inflicted injuries, as well as improvements in children’s emotional distress. With families, some benefits have included improved parent-child relationshipsreductions in parent stress, and improvements in children’s executive functioning skills. You can find more information on these and other published findings below.

What research has been done on CPS in schools?

Multiple studies on Collaborative Problem Solving have been done in schools. One study found an association between CPS and lower rates of restrictive discipline and teachers’ stress. Another found associations between CPS and improved student behavior, as well as improvements in thinking skills. A third study examined how teachers’ beliefs regarding students’ thinking skills may affect how they respond to classroom misbehavior.

What research has been done on CPS in clinical/mental health settings?

A number of studies on CPS have been done in clinical/mental health settings. This includes studies on outpatient therapy for Oppositional Defiant Disorder and ADHD, a study on how CPS may impact restraints and seclusions in inpatient psychiatry and residential and day treatment programs, as well studies on the implementation and evaluation of the approach in inpatient and residential programs.

Can CPS reduce use of restraint and/or seclusion?

There have been multiple studies on the reduction of restraint and/or seclusion in organizations that are using CPS. These studies have been conducted in inpatient units in the U.S. and New Zealand and residential and day treatment programs.

Is the Thinking Skills Inventory empirically validated?

Yes. We have a paper on our Thinking Skills Inventory (TSI), a tool that evaluates strengths and struggles in five areas of thinking skills. The TSI is a valid and reliable way to identify variation in skill domains relevant to a range of psychological difficulties, which may be useful for treatment planning and making referrals for further evaluation.

Is the CPS Adherence and Impact Measure (CPS-AIM) empirically validated?

There are three versions of the CPS-AIM: one for Parents, one for Educators, and one for Clinical Staff. Each CPS-AIM measures factors believed to be directly impacted by receiving CPS training, including adherence to the philosophy that ‘skill not will’ is the root of challenging behavior. Our research team has made this report available; it describes the psychometric properties of these measures, including reliability and validity.

Is there an empirically validated way to assess whether providers are doing CPS with integrity?

Yes, staff at Think:Kids have developed an audio coding system to assess providers’ integrity to CPS. This coding system is called the Collaborative Problem Solving Manualized Expert-Rated Integrity Coding System (CPS-MEtRICS) which is under review for publication. When you get trained in CPS, you will learn to use shorter integrity tools that have been drawn directly from the CPS-MEtRICS.

How does Think:Kids use what is known by Implementation Science to inform implementation of CPS?

Think:Kids follow the latest research in implementation science to help inform and direct our work implementing CPS in schools and a variety of other agencies. We recently published an article that describes how we use the Active Implementation Frameworks to help guide the implementation of CPS throughout an entire system.

Are there special materials/measures/survey tools designed for research on CPS?

Yes, you can find these in the “Research Tools” section at the bottom of this page. Once you have received training and coaching in CPS, you will receive additional materials and measures relevant to your setting.
