Autism Assessments (waitlist full)

Autism assessments are provided by Karen Weigle, PhD. Dr. Weigle uses the Autism Diagnostic Observation Schedule, second edition (ADOS-2) and other diagnostic tools. The ADOS-2 is a standardized observational assessment of an individual’s communication, socialization, and play/creativity along with other behaviors characteristic of Autism Spectrum Disorder. The ADOS-2 has many different modules depending on the client’s verbal ability and age and is appropriate for ages 12 months up to any adult age. The results of the assessment are provided to the client in a detailed report.  

What does an autism assessment look like?

The assessment usually takes place over four visits. The first visit is an intake session where the caregiver/s and/or individual being assessed answer questions, complete informational forms, and are established as a client. The client is then scheduled for two assessment sessions on different days to allow for a broader sample of the client’s behavior. Each assessment session usually lasts between 40 and 50 minutes. The psychologist then scores the assessment and writes a detailed clinical diagnostic report. The parents and/or client attend a final follow-up session where the psychologist delivers the report, explains it in detail, answers questions, and discusses relevant referrals and future plans. 

 

Do I need an assessment before getting other types of services?

No! Individuals can seek and receive treatment while they are on the waitlist to be assessed. For example, if a child is demonstrating delays in speech or social skills or is experiencing sensory issues, anxiety, or behavior problems, parents should seek specialized therapeutic treatment immediately. Therapists such as counselors, Speech and Language Pathologists, Occupational Therapists, and ABA therapists will provide their own specialized evaluations and begin treatment. You DO NOT have to wait until after an autism assessment to seek therapy. The main purpose of the ADOS-2 assessment is to provide a diagnosis as well as a detailed professional report, but is not a prerequisite for services in most cases.


Individuals seeking an autism assessment should contact the CAC at 423-531-6961, opt 2 AND contact other places on this list of local evaluation providers.

Cognitive Behavior Therapy (waitlist full)

Karen Weigle, PhD, Amy Rutherford, LPC, and Alyce Benson, LCSW provide Cognitive Behavior Therapy (CBT) for children and adults with Autism Spectrum Disorders. This type of therapy has decades of empirical evidence supporting their effectiveness, particularly for teaching skills, decreasing anxiety, and improving mood. Our clinicians specialize in providing therapy for individuals with autism. They recognize how aspects of autism can sometimes contribute to anxiety, depression, social skill deficits, decreased motivation, tantrums, difficulty transitioning, and relationship problems. 

 

What is Cognitive Behavior Therapy (CBT)?

  • CBT is based on the idea that how we feel, think, and behave are naturally intertwined. 

  • CBT helps individuals identify the relationships between thinking patterns, disruptive behavior, and emotional responses in upsetting or impairing situations. 

  • CBT requires active participation by the individual in the form of in-session exercises, as well as homework assignments to be completed between sessions. 

  • Our therapists have adapted the principles and methods of CBT to address the needs of individuals with autism and families.

 

How can CBT help individuals with ASD? 

  • Teaching coping skills, social skills, emotional identification and regulation, education.

  • Parent-child interaction and helping parents learn strategies for helping their children.

  • Dealing with emotions.

  • Understanding a diagnosis of Autism Spectrum Disorder.

 

Who can receive these therapies at the CAC?

  • Young children to adults of any age who have autism or suspected autism.

  • Verbal skills are needed to engage in Cognitive Behavior Therapy.

  • These therapies are also for parents who learn techniques to use outside of the clinic and to help them better understand their children with autism and their needs.


Individuals seeking CBT should contact the CAC at 423-531-6961, opt 2 AND contact other places on this list of local therapy providers.

ABA Therapy (waitlist full)

The CAC has two Board Certified Behavior Analysts, Anna Straussberger, BCBA and Bailey Gregory, BCBA. Both provide Applied Behavior Analysis (ABA) therapy and supervise several Registered Behavior Technicians. The therapists meet with caregivers, provide functional assessments to determine why a child is behaving in a certain way, and then design treatment plans and train caregivers to implement strategies at home. ABA therapy is intensive (several hours per week) and parents are expected to be involved in sessions and to record weekly data. The therapy occurs in the clinic, home and community.

 

What is Applied Behavior Analysis (ABA) Therapy?

  • ABA is a scientifically validated approach to understanding behavior and how it is affected by the environment.

  • ABA aims to decrease dangerous or harmful behaviors and increase desirable behaviors and skills.

  • ABA teaches caregivers to interact differently with their child to attain and maintain desired results after therapy ends.

  • Since the 1960s, therapists have been applying ABA to help children with autism and related developmental disabilities.

 

Who benefits most from ABA Therapy? 

  • Children exhibiting behavior problems that significantly impact daily family life.

  • Individuals with language delays.

  • Individuals needing to learn specific behaviors and skills.​

 

Who can get ABA Therapy at the CAC?

Children ages 18-months-old to 6-years-old.

Anna Straussberger, M.A., BCBA, interest in the field began suddenly after reading a Newsweek article pointing to elevated incidence of Autism in children. Within two minutes, Anna diverted from her original plan to become a high school English teacher and started pursuing a career in working with individuals affected by an Autism Spectrum Disorder. Since 2008, Anna has used the principles of Applied Behavior Analysis to work in residential, home-based, school, and community settings to foster functional communication, social development, daily living skills, and prevocational readiness in adolescents and young adults with an ASD. Through her work, Anna formed an interest in helping these individuals and their families in transition gain the knowledge and skills to live independently, foster meaningful relationships, and interact with the community through employment or other fulfilling means. Through her work, Anna also developed an interest in helping support parents, siblings, and other caregivers who have a loved one with an ASD. With this aim in mind, Anna returned to school, and she received a MA in Mental Health Counseling and Behavioral Medicine from the Boston University School of Medicine in 2014. She then went on to earn her BCBA through the Florida Institute of Technology. Anna’s goal is to continue to help individuals with autism and their families develop the competencies to lead independent, healthy, and happy lives.
