Psychodiagnostic Testing

Have you or a loved one been recommended for a psychodiagnostic assessment by a psychiatrist or a physician? If so, you might have questions about what it entails.

Simply put a psychodiagnostic evaluation aids in diagnosing and clarifying queries around behavior, mood, emotional function, personality traits, and cognitive processes.

This psycho-diagnosis test typically involves a comprehensive and intricate examination to determine the psychological elements that might obscure a precise diagnosis and treatment plan.

The resulting report is commonly used to answer referral-specific queries (e.g., testing for diagnostic clarification, differentiation between Axis I and Axis II disorders, comorbidity, psychological disorders secondary to medical conditions or substance abuse, current psychosocial stressors, and adaptive ability).

Applications of Psychodiagnostic Evaluation:


  • If a client isn’t responding to psychopharmaceutical treatment, and a diagnostic clarification is needed.
  • In cases where there’s a history of trauma, particularly long-term exposure, and current symptoms are suspected to be partially attributed to these experiences.
  • If substance abuse is suspected to be primarily contributing to other psychological disorders or has arisen as a secondary issue due to an individual’s inability to use healthier, adaptive coping mechanisms.
  • When interpersonal relationship issues are impacting an individual’s functionality significantly.
  • When the source of a child’s behavioral or emotional problems is unclear to parents or teachers, especially if it’s affecting academic performance. This becomes particularly important when there’s a noticeable gap between the child’s IQ and achievement testing.
  • In instances where there’s a history or current concern of self-harm or suicidal ideation.

What to anticipate during a psychodiagnostic assessment:

A psychodiagnostic test is often comprehensive and more time-intensive than specific referrals (e.g., ADHD testing). Initially, a licensed clinical psychologist will conduct a 1-hour intake session, where they’ll compile all relevant history, background information, and current symptoms.

Consultations with other family members, teachers, or physicians are usually required to develop a holistic profile of the individual. The psychodiagnostic evaluation typically takes around 6 hours, which can be divided into two to three sessions. Because these evaluations are very thorough, the report usually takes 6-8 weeks to complete.

After the report is finalized, our office will reach out to you to arrange a follow-up appointment. You’ll receive a copy of the report and have the opportunity to discuss any questions or concerns you might have.
