About Psychological Testing
What is psychological testing for adults?
Psychological testing for adults is a structured clinical process — conducted by a licensed psychologist — that uses interviews, standardized assessments, and validated tools to diagnose mental health conditions and produce a written report with specific treatment recommendations.
- Goes beyond a symptom checklist or therapy intake — uses multiple methods to triangulate findings
- Produces a formal written report the client keeps, usable for treatment, prescriber conversations, and accommodations
- Ends with a feedback session where the psychologist walks through findings and answers questions
At Peachtree Psychology in Roswell, GA, Dr. Alex Crenshaw, PhD offers adult psychological testing for ADHD, OCD, anxiety, depression, and related conditions. Evaluations range from $700 for a Standalone Diagnostic Evaluation to $2,300 for a Full ADHD Assessment. View all testing services.
Who needs psychological testing?
Adults who have struggled with attention, mood, anxiety, or behavior without a clear diagnosis — or who have been in therapy without getting better — are the most common candidates for psychological testing.
- People who suspect a specific condition (ADHD, OCD, PTSD, depression) and want clinical confirmation
- People whose therapy isn't working and want to understand whether the diagnosis or treatment approach is correct
- People who need formal documentation of a psychological condition for workplace accommodations or prescriber conversations
Dr. Alex Crenshaw at Peachtree Psychology's Roswell office near Atlanta offers an initial phone screening to help adults determine whether a formal evaluation is the right next step — and which evaluation fits their situation. Learn about the Standalone Diagnostic Evaluation.
What is the difference between psychological testing and a screening?
A screening is a brief preliminary tool that flags whether further evaluation is warranted; psychological testing is the full evaluation itself — a multi-method, clinician-led process that produces a confirmed diagnosis and specific treatment recommendations.
- Screenings are short questionnaires — they suggest a condition may be present but cannot confirm it
- Psychological testing includes clinical interview, structured diagnostic tools, standardized assessments, written report, and a feedback session
- A positive screening result is a reason to pursue testing, not a diagnosis on its own
At Peachtree Psychology in Roswell, GA, every evaluation begins with a phone screening to determine which type of testing is appropriate. The full evaluation process — conducted by Dr. Alex Crenshaw, PhD — produces a written clinical report with diagnosis and treatment recommendations.
What does a psychological evaluation report include?
A psychological evaluation report includes the client's history, the methods used, results of each assessment component, a clinical diagnosis, and specific treatment recommendations — written by the evaluating psychologist and provided to the client to keep.
- Documents the diagnostic conclusions and the clinical evidence supporting them
- Includes specific recommendations for therapy type, medication consultation, or other interventions
- Can be shared with other providers, prescribers, employers, or academic institutions
Dr. Alex Crenshaw at Peachtree Psychology provides a full written report with every evaluation — including the Standalone Diagnostic Evaluation ($700) and the Full ADHD Assessment ($2,300) — along with a dedicated feedback session to review findings in person at the Roswell, GA office.
How accurate is psychological testing?
Psychological testing conducted by a licensed psychologist using validated, multi-method assessment is highly accurate — far more reliable than a brief screening, a self-diagnosis, or a single clinical impression.
- No single tool is definitive — accuracy comes from using multiple methods together (interview, structured diagnostic tools, standardized tests, self-report)
- The multi-method approach significantly reduces misdiagnosis risk
- Licensed psychologists with specialty training in the relevant conditions produce the most accurate results
Dr. Alex Crenshaw, PhD, at Peachtree Psychology in Roswell, GA brings specialty training in ADHD, OCD, PTSD, and anxiety disorders to the evaluation process. As an Assistant Professor of Psychology at Kennesaw State University, his clinical approach is grounded in current research on diagnostic accuracy and treatment effectiveness.
Do I need a referral to get psychological testing?
No — you do not need a referral from a physician or therapist to schedule psychological testing at Peachtree Psychology.
- Adults can contact Peachtree Psychology directly to schedule an initial phone screening
- The phone screening — not a referral — determines which evaluation is the right fit
- Self-referral is common; many clients come in without any prior clinical contact
Dr. Alex Crenshaw at Peachtree Psychology's Roswell, GA office accepts new clients for psychological testing without a referral. Call 678-381-1687 or use the contact form to get started. Schedule a consultation.
How long does a psychological evaluation take?
A psychological evaluation at Peachtree Psychology takes most of a Saturday morning for a Full ADHD Assessment, or two separate one-hour appointments — a clinical interview and a feedback session — for the Standalone Diagnostic Evaluation and condition-specific evaluations.
- Full ADHD Assessment: extended Saturday morning session including computerized testing, clinical interview, and scoring
- Standalone Diagnostic Evaluation, OCD, anxiety, and depression evaluations: 60-minute clinical interview + 60-minute feedback session
- Written report is prepared between the interview and feedback sessions
All evaluations at Peachtree Psychology begin with a phone screening before any in-person appointments are scheduled. Dr. Alex Crenshaw's Roswell, GA office will walk you through the full timeline for your specific evaluation during that call.

View testing services and pricing.
Does insurance cover psychological testing?
Most insurance plans do not cover psychological testing directly at Peachtree Psychology, which is self-pay, but many clients receive partial reimbursement by submitting a superbill to their insurance company.
- Peachtree Psychology does not bill insurance directly — all evaluations are self-pay
- A superbill (itemized receipt with diagnosis and procedure codes) is provided on request for out-of-network submission
- Coverage varies by plan — call your insurer and ask specifically about out-of-network psychological testing benefits
Dr. Alex Crenshaw at Peachtree Psychology's Roswell, GA office provides superbills for all evaluations upon request. Clients with PPO plans that include out-of-network mental health benefits often receive partial reimbursement after direct submission to their insurer.
What is a superbill?
A superbill is a detailed itemized receipt from a healthcare provider that includes the diagnosis code, procedure codes, provider credentials, and date of service — everything an insurance company needs to process an out-of-network reimbursement claim.
- The client submits the superbill directly to their insurance company — not the provider
- The insurer reimburses the client according to the plan's out-of-network benefit terms
- Not all plans cover psychological testing — verify your benefits before scheduling
Peachtree Psychology provides superbills upon request for all evaluations conducted by Dr. Alex Crenshaw at the Roswell, GA office. Ask about superbill availability when you call to schedule.
Why does ADHD testing cost more than other evaluations?
ADHD testing costs more than a standard diagnostic evaluation because it requires significantly more clinician time — including computerized testing, structured diagnostic instruments, scoring and interpretation, a full written report, and a 90-minute feedback session.
- Computerized testing objectively measures attention, processing speed, and impulse control — this alone takes substantial time to administer and interpret
- The Full ADHD Assessment at Peachtree Psychology involves more assessment methods than a standard evaluation
- The 90-minute feedback session (vs. 60 minutes for other evaluations) reflects the volume of findings to review
The Full ADHD Assessment at Peachtree Psychology is $2,300 and takes most of a Saturday morning at the Roswell, GA office. Dr. Alex Crenshaw, PhD conducts a comprehensive multi-method evaluation — the cost reflects the full clinical process, not just the testing day. Learn about the Full ADHD Assessment.
ADHD Testing
Can adults be diagnosed with ADHD?
Yes — ADHD is commonly diagnosed in adults, often for the first time in their 30s, 40s, or later, particularly in people who developed strong coping strategies in school that masked their symptoms.
- ADHD is a lifespan condition — it does not disappear after childhood
- High-achieving adults are frequently undiagnosed because academic success concealed the underlying deficit
- A comprehensive adult ADHD evaluation — not a brief screening — is the only way to confirm the diagnosis
Dr. Alex Crenshaw offers Full ADHD Assessments for adults at Peachtree Psychology's Roswell, GA office, serving clients throughout the Atlanta metro including Alpharetta, Sandy Springs, Johns Creek, Buckhead, East Cobb, and Marietta. The evaluation is $2,300 and includes computerized testing, structured diagnostic interview, full written report, and a 90-minute feedback session. Learn about adult ADHD testing.
What is the difference between ADHD and anxiety in adults?
ADHD and anxiety both cause difficulty concentrating and follow-through problems, but ADHD involves consistent executive function deficits across contexts while anxiety involves worry-driven avoidance — and they frequently co-occur, making a formal evaluation essential to distinguish them.
- ADHD: attention regulation problems are consistent regardless of interest level or worry — driven by executive function deficits
- Anxiety: attention problems are driven by intrusive worry and hypervigilance — concentration improves when anxiety is reduced
- Up to 50% of adults with ADHD also have an anxiety disorder — both conditions can be present simultaneously
Dr. Alex Crenshaw at Peachtree Psychology in Roswell, GA is trained in both ADHD evaluation and anxiety disorder treatment, including Exposure and Response Prevention and CBT. The Full ADHD Assessment ($2,300) and Standalone Diagnostic Evaluation ($700) are both designed to examine the full picture, including anxiety, rather than assess a single condition in isolation. Learn about anxiety assessment.
What should I avoid before ADHD testing?
On the day of computerized ADHD testing at Peachtree Psychology, clients are asked to avoid caffeine and other stimulants to ensure baseline attention and processing results are accurate.
- Caffeine and stimulant avoidance applies specifically to the computerized testing portion of the assessment
- If you take prescription stimulant medication for ADHD, discuss this with Dr. Crenshaw during your phone screening — guidance is individualized
- No food restrictions apply beyond stimulant avoidance
The Full ADHD Assessment at Peachtree Psychology in Roswell, GA is conducted as an extended Saturday morning session. Dr. Alex Crenshaw will review all preparation instructions during the phone screening and before the testing day. Learn about the Full ADHD Assessment.
OCD Testing
How do I know if I have OCD?
OCD is characterized by a specific cycle — unwanted intrusive thoughts (obsessions) that cause anxiety, followed by mental or physical rituals (compulsions) performed to reduce that anxiety temporarily — and a formal evaluation is the only reliable way to confirm the diagnosis.
- Compulsions can be behavioral (checking, cleaning, arranging) or entirely mental (reassuring yourself, reviewing memories, neutralizing thoughts)
- OCD content is often deeply disturbing — harm, contamination, religion, sexuality — and most people do not disclose it without direct clinical prompting
- OCD is frequently misdiagnosed as generalized anxiety; standard anxiety treatment can inadvertently reinforce OCD
Dr. Alex Crenshaw at Peachtree Psychology in Roswell, GA has specialty training in Exposure and Response Prevention (ERP), the gold-standard treatment for OCD, and brings that clinical depth to the diagnostic process. An OCD evaluation is $700 and includes a structured clinical interview, written report, and feedback session. Learn about OCD testing.
What is the difference between OCD and generalized anxiety?
OCD involves a specific obsession-compulsion cycle with intrusive thoughts and rituals that temporarily neutralize anxiety, while generalized anxiety involves diffuse worry about life circumstances without the compulsive ritual structure — and standard anxiety treatment can make OCD worse if the two are confused.
- Generalized anxiety: wide-ranging worry about realistic concerns (work, health, relationships) without a clear ritual component
- OCD: specific intrusive thoughts trigger anxiety, and a compulsion (mental or behavioral) is performed to reduce it — temporarily, until the cycle restarts
- The compulsion is the diagnostic key — without it, OCD is frequently mislabeled as anxiety
Because the distinction between OCD and anxiety determines the entire treatment approach, a formal evaluation with a specialist matters. Dr. Alex Crenshaw at Peachtree Psychology in Roswell, GA has specialty training in ERP for OCD and CBT for anxiety disorders. OCD evaluation: $700. Anxiety assessment: $700. Learn about OCD testing.
Anxiety and Depression
Can a psychological evaluation diagnose depression?
Yes — a psychological evaluation can diagnose major depressive disorder, persistent depressive disorder (dysthymia), and other mood conditions, while also distinguishing depression from burnout, grief, and conditions like anxiety or ADHD that frequently co-occur.
- Evaluation identifies the specific type of depression present — not all depression responds to the same treatment
- Persistent depressive disorder (dysthymia) is frequently undertreated because it resembles personality rather than illness
- Bipolar depression is commonly misdiagnosed as unipolar depression — a distinction that significantly affects medication management
Dr. Alex Crenshaw at Peachtree Psychology offers depression evaluations for adults at the Roswell, GA office as part of the Standalone Diagnostic Evaluation ($700). The written report includes diagnosis, clinical reasoning, and specific treatment recommendations — including whether medication consultation is indicated. Learn about depression evaluation.
I have been in therapy for anxiety for years and still struggle. Should I get tested?
Yes — persistent anxiety that hasn't fully responded to therapy is one of the most common reasons adults pursue a formal psychological evaluation, often revealing a missed diagnosis like OCD, PTSD, or ADHD, or a mismatch between the anxiety type and the treatment approach.
- OCD is frequently treated as generalized anxiety — and standard anxiety treatment can reinforce OCD rather than resolve it
- PTSD produces significant anxiety symptoms that require trauma-focused treatment, not general anxiety management
- ADHD co-occurring with anxiety is commonly missed, and untreated ADHD can make anxiety treatment far less effective
Dr. Alex Crenshaw at Peachtree Psychology in Roswell, GA offers anxiety assessments for adults who want diagnostic clarity — including those with prior treatment history that hasn't fully resolved their symptoms. The evaluation is $700 and includes a 60-minute clinical interview, written report, and feedback session. Learn about anxiety assessment.
Using Test Results
Can psychological testing results be used for workplace accommodations?
Yes — a written evaluation report from a licensed psychologist documenting a psychological condition can support ADA workplace accommodation requests, including extended deadlines, reduced-distraction environments, and flexible scheduling.
- The written report from a Peachtree Psychology evaluation documents diagnosis, clinical findings, and functional impact
- Accommodation requests typically require documentation from a licensed mental health professional — a psychologist's report satisfies this
- If workplace documentation is your primary goal, mention it during the phone screening so the report addresses your specific needs
Dr. Alex Crenshaw at Peachtree Psychology in Roswell, GA provides comprehensive written reports for all evaluations — including ADHD, OCD, anxiety, and depression assessments. Reports are provided to the client to use as needed, including for employer or HR documentation purposes. Learn about the Standalone Diagnostic Evaluation.
