Psychological Assessments for OCD, ADHD, Autism & Mood Disorders
Clear answers about what’s going on.
Comprehensive, evidence-based evaluations for ages 6 and up. We go beyond surface-level screening to better understand what is happening and provide recommendations you can use in treatment, school, work, or daily life.
What we assess
Different concerns call for different kinds of assessment.
Testing is only one part of an assessment. We also use interviews, clinical history, and observation to understand what is going on and what will be most useful afterward.
OCD assessment
Clarifies whether intrusive thoughts, compulsions, avoidance, reassurance seeking, or related symptoms are best explained by OCD, another condition, or a combination of concerns.
ADHD assessment
Evaluates attention, executive functioning, impulsivity, hyperactivity, self-regulation, and the impact of symptoms across school, work, relationships, and daily life.
Autism assessment
Explores social communication, sensory experiences, restricted or repetitive patterns, adaptive functioning, masking, developmental history, and other aspects of autistic presentation.
Mood disorder assessment
Evaluates symptoms related to depression, mood changes, emotional functioning, and other concerns that may overlap with OCD, ADHD, autism, or anxiety.
Not sure which assessment you need? You do not have to figure that out on your own. Start by telling us the questions you are hoping to answer.
Why assessment can help
Sometimes the question is not simply, “Do I have this?”
OCD, ADHD, autism, anxiety, and mood disorders can look similar on the surface, and more than one can be present at the same time.
The goal is to understand what is present, how different concerns interact, and what that means for treatment or support.
Clarify what is happening
Distinguish between overlapping symptoms and identify co-occurring concerns when appropriate.
See strengths, not only challenges
Assessment gives a fuller picture of how someone thinks, learns, communicates, adapts, and functions.
Know what to do next
Results should translate into practical recommendations rather than ending with a diagnosis alone.
Why OCD, ADHD, and autism can be hard to tell apart
These three can look similar from the outside, and more than one can be present at once. The question is not only what a behavior looks like, but what is driving it.
Repetition, routines & rigidity
Repetitive behavior may be a compulsion used to reduce OCD distress, a preferred routine that supports predictability, or something connected to attention, regulation, or habit.
Attention & executive functioning
Trouble starting tasks, shifting attention, organizing, remembering steps, or following through shows up across ADHD, autism, and OCD for different reasons.
Anxiety, overwhelm & avoidance
Avoidance or distress may come from obsessional fear, sensory overload, uncertainty, executive-function demands, or a combination of factors.
The same behavior can mean different things. Assessment helps us understand what is driving it so recommendations fit the person, not just the symptom.
The assessment process
A clear path from paperwork to feedback.
The exact amount of testing depends on the evaluation. We will tell you what to expect before your testing day.
Step 01 · Paperwork
Complete secure forms ahead of time
You will receive intake forms before your appointment so your psychologist can begin with important background information.
Step 02 · Intake
Talk through the questions bringing you in
For OCD assessments, intake and testing are completed in a single two-hour session. ADHD and autism evaluations begin with a separate intake appointment before the testing day.
Step 03 · Testing
Complete the measures selected for your evaluation
- OCD only — completed during intake
- ADHD, adult — about 4 hours
- Autism, adult — about 2 hours
- ADHD + autism — about 5 hours
- ADHD + autism + OCD — about 5 hours
Step 04 · Feedback & report
Review your results and next steps
Feedback is typically scheduled two to six weeks after testing, depending on the evaluation. You will review the findings and receive your written report.
What you receive
Results you can actually use.
Your psychologist will explain what the findings mean and include recommendations based on the questions that brought you in.
A summary of the information gathered during the evaluation and what it means.
Scores from standardized measures, explained in understandable language.
Consideration of overlapping or co-occurring concerns such as OCD, ADHD, autism, anxiety, or mood disorders.
Attention to abilities and areas of strength, not only difficulties or diagnoses.
Practical next steps for therapy, school, work, home, and everyday functioning.
Guidance on 504 plans, IEPs, workplace accommodations, referrals, or other supports when appropriate.

- Compulsive behaviors and mental rituals
- OCD themes and symptom patterns
- Severity and frequency
- Avoidance and safety behaviors

- Planning and organization
- Time management
- Working memory and processing
- Emotional regulation
- Task initiation and persistence
- Academic, social, work, and daily functioning

- Restricted or repetitive patterns
- Adaptive functioning
- Developmental history
- Social reciprocity
- Masking and camouflaging

- Emotional functioning
- Functional impact
- Co-occurring anxiety or OCD symptoms
