The Institute for Behavior Change

Specializing in Intensive Behavioral Health Services


About The Institute for Behavior Change (IBC)

The Institute for Behavior Change was incorporated as a nonprofit organization in 1997 by Licensed Psychologist Steven Kossor. Our model of “Intensive Behavioral Health Services” (IBHS) is funded by the Medicaid EPSDT mandate at no cost to parents. 

Our Mission

Our staff build hope and courage in children and families.  Hope for a better future and the courage to do the work necessary to create it.  We are mental health treatment professionals with decades of experience treating children in their homes and schools, addressing challenging behavior therapeutically.

Why We Started...

Since 1981, our staff have provided in-home and in-school treatment services to children – about ten years before any other provider of these services in Pennsylvania.  Our staff are the preferred providers in several Southeastern Pennsylvania school districts.  All of our services are absolutely free to families, regardless of family income.  It is our aim to distribute up-to-date information about community-based treatment delivery and how to obtain and maintain behavioral health insurance funding.  Our staff acquire and distribute this information reliably, and apply it to deliver excellent treatment services.

Tailor-Made Assessments, Treatment Plans and Outcome Measurements

Our Assessments, Treatment Plans and Outcome Measurements are continually updated to give parents, professionals and attorneys the support needed to advocate for children.  Our staff integrate effectively into school and daycare settings to provide behavioral support.  We don’t infringe upon the roles of teachers and administrators while providing 20, 30 or more weekly hours of individualized, intensive behavioral support for children with Autism, ADHD and other challenges.

Let's get this information out!

Our founder and Executive Director is acknowledged as an expert witness in Federal court regarding mental health treatment and behavioral support for children through the Early and Periodic Screening, Diagnosis and Treatment (EPSDT) mandate of the Medicaid Act.   We offer consultation services regarding Medicaid and private insurance funding, effective treatment outcome measurement and behavioral treatment planning to parents, professionals, attorneys and advocates.

Our Treatment Plans work!

Our treatment programs combine evidence based "Applied Behavior Analysis"  (ABA) principles with "wraparound" practices.  Our treatment programs have been studied by researchers at:  

  • The University of North Carolina at Chapel Hill (2007)

  • Thomas Jefferson University in Philadelphia (2010)

  • Villanova University (2012)

  • Immaculata University (2013)

More than 1,000 treatment plans were analyzed.  In 75% of cases, physical aggression, noncompliance with adult prompts, inattentiveness to environmental safety, communication immaturity and socialization deficits reduced significantly (p<.0001) in less than 6 months.
