Neurodiversity-Affirming Autism & ADHD Assessments

 At Creekside Therapeutics, we believe that assessment should be a process of discovery, validation, and hope. We offer a collaborative, neurodiversity-affirming approach to diagnostic evaluations for autism and/or ADHD for children, adolescents, and adults.

• Collaborative Discovery: We work together with you throughout the process, valuing your input and insights.
• Meaning-Making: We help you understand your assessment results and what they mean for your life.
• Empowerment: We provide you with the knowledge and tools to advocate for yourself and access support.
• Neurodiversity-Affirming Tools: We utilize intentionally selected assessment tools that are respectful and non-pathologizing.

Our evaluations provide clarity for a wide range of individuals, including: 

• Individuals seeking formal identification or an "official" diagnosis.
• Those who suspect they may have autism or ADHD and want clarity and understanding.
• People seeking a written report with recommendations for support and accommodations.
• Ages 6 to adult.

Our evaluations are:

• Healing-centered: We prioritize your well-being and create a safe and supportive environment.
• Gender-inclusive: We recognize and affirm the experiences of all genders.
• Non-pathologizing: We view neurodiversity as a natural variation, not a deficit.
• Rooted in the neurodiversity paradigm: We embrace the strengths and unique perspectives associated with autism and ADHD.

At Creekside Therapeutics, we offer comprehensive autism evaluations using evidence-informed assessment tools such as the MIGDAS-2 (Monteiro Interview Guidelines for Diagnosing Autism Spectrum, Second Edition) and the ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) when clinically appropriate.

Autism evaluations are not just about checking boxes — they are about understanding how a person experiences the world, processes information, communicates, and regulates sensory and emotional input. Our assessment process integrates standardized tools with a detailed developmental history and clinical interview to provide a thoughtful, individualized diagnostic picture.

The MIGDAS-2 is a qualitative, sensory-based autism assessment framework that helps clinicians understand how autistic traits show up in everyday life. Rather than focusing only on deficits, MIGDAS-2 explores areas such as:

• sensory processing and regulation
• social communication style
• interests and attention patterns
• cognitive processing and problem solving
• daily functioning and energy use
   

The MIGDAS-2 includes different versions designed for children, adolescents, and adults, and we always administer the age-appropriate format to ensure the assessment reflects the individual’s developmental stage and lived experience.

This approach is particularly helpful for individuals who may have masked or adapted their autistic traits over time, including many late-identified autistic adults.

The ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is a structured observational assessment widely considered one of the gold-standard tools used in autism evaluations. It involves conversational and interactive activities designed to help clinicians observe social communication, interaction patterns, and behavioral characteristics associated with autism.

The ADOS-2 includes multiple modules designed for different ages and language levels, and we administer the module that best matches the individual’s developmental and communication profile. The ADOS-2 is used when clinically appropriate and interpreted within the broader context of developmental history and other assessment measures.

Autism evaluations at Creekside typically include:

• a detailed developmental and psychosocial history 
• structured clinical interview
• MIGDAS-2 assessment using the appropriate age version
• ADOS-2 observational assessment using the appropriate module (when indicated)
• standardized screening measures
• diagnostic feedback and written report
• personalized recommendations and resources
   

Our goal is to provide clear diagnostic insight while honoring neurodiversity and the lived experiences of autistic individuals.

Our collaborative process includes:

1. Gathering of social and developmental history: We'll collect information about your background and experiences.
2. Diagnostic interview session(s): We'll conduct in-depth interviews to understand your unique needs and challenges.
3. Self-report measures/questionnaires: You'll complete questionnaires to provide further insights into your experiences.
4. A written report and meeting to review outcomes: You'll receive a comprehensive report with our findings, diagnosis (if indicated), and personalized recommendations.
