Psychological Assessment
Understanding how you
think, learn, and feel.
A psychological evaluation goes beyond a diagnosis. It's a detailed, personalized picture of how your mind works- your strengths, your challenges, and what you need to thrive.
At Seattle Counseling & Wellness, our evaluations are collaborative, thorough, and written in plain language you can actually use.
Who we Assess:
Developmental, learning, and behavioral concerns from early childhood through adolescence
Children
Ages 3 and up
Adults
ADHD, learning differences, mood and personality concerns, and late-identified autism
18 and Older
Older Adults
Memory concerns, cognitive change, dementia evaluation, and neuropsychological assessment
Seniors and Elders
Areas of Assessment
Our evaluations are comprehensive and individualized. Below are the areas Dr. Duffield assesses- many clients present with concerns that span several of these areas, and each evaluation is built around you.
What we evaluate:
Autism Spectrum Disorder
Comprehensive ASD evaluation drawing on clinical interview, observation, and gold-standard assessment tools. Particularly attuned to late-identified adults and women whose presentations were missed earlier in life.
Children 3+, Adolescents, Adults
Intellectual Disability
Thorough assessment of cognitive and adaptive functioning to understand strengths and areas of need. Results support planning for education, services, and daily life.
Children, Adolescents, Adults
Dementia & Cognitive Decline
Sensitive evaluation of memory, orientation, language, and executive function for older adults and families navigating cognitive change. Includes guidance on next steps and care planning.
Children, Adolescents, Adults
ADHD & Attention Concerns
Assessment of attention, executive function, impulse control, and hyperactivity across home, school, and work settings. Includes ruling out other conditions that can look like ADHD.
Children, Adolescents, Adults
Fetal Alcohol Spectrum Disorders
Specialized FASD evaluation using University of Washington diagnostic guidelines. Dr. Duffield has advanced training through UW's FASD Diagnostic & Prevention Network.
Children, Adolescents, Adults
Mood, Anxiety & Personality
Evaluation of complex emotional, behavioral, and personality patterns when the picture isn't clear. Helps distinguish diagnoses and clarify what kind of therapy or support would actually help.
Children, Adolescents, Adults
Learning Disorders
Evaluation of reading, writing, and math abilities to identify dyslexia, dyscalculia, and related learning differences. Results include specific school and workplace accommodation recommendations.
Children, Adolescents, Adults
Traumatic Brain Injury
Neuropsychological assessment following TBI to document cognitive impact on memory, attention, processing speed, and daily functioning. Supports return-to-work, school, and legal documentation.
Children, Adolescents, Adults
Differential DiagnosisWhen symptoms fit more than one explanation, a targeted evaluation helps sort out what's actually driving them, whether that's ADHD vs. anxiety, autism vs. a learning difference, or depression vs. early cognitive decline. Getting the diagnosis right means treatment and support can hit the right target.

What to expect
The Evaluation Process:
Dr. Duffield takes a collaborative, strengths-based approach. The goal isn't simply to assign a diagnosis- it's to help you or your child genuinely understand how you think, learn, feel, and function.
Every evaluation is tailored. You'll receive a written report with clear findings and concrete recommendations you can bring to your school, employer, physician, or therapist.
Most evaluations are completed across two to three appointments, with a feedback session to review results together. You're encouraged to ask questions throughout.
A brief intake call to understand your concerns, confirm fit, and answer questions about the evaluation process and cost.
❋ 1. Initial Consultation
An in-depth conversation covering developmental history, current functioning, and what's been challenging. For children, parents participate in this session.
❋ 2. Clinical Interview
Standardized assessments tailored to your referral question — cognitive, academic, behavioral, and/or neuropsychological measures as appropriate.
❋ 3. Testing Session(s)
A feedback session to review findings together, followed by a written report with clear diagnoses, strengths, and actionable recommendations.
❋ 4. Feedback & Report
