Personality Assessment — What to Expect & How to Book
A personality assessment is a structured process used to understand stable, long-standing patterns in how someone thinks, feels, and relates to others — as distinct from a specific diagnosis or a single symptom cluster. It can be used for diagnostic clarification (including personality disorder assessment), to support treatment planning, or in some cases for occupational or developmental purposes.
This page covers what a personality assessment involves, who it’s for, what it typically costs, and how to prepare.
The process
What does a personality assessment involve?
- Background & history
- Relevant developmental, relationship, occupational, and mental health history.
- Clinical interview
- A detailed conversation exploring long-standing patterns in thinking, emotion, behaviour, and relationships over time, not just current symptoms.
- Standardised personality measures
- Validated psychometric tools selected based on the referral question, which may assess broad personality traits, personality disorder features, or specific patterns relevant to the referral.
- Collateral information, where relevant
- Input from people who know the person well can sometimes add useful context, particularly where self-insight into long-standing patterns is limited.
- Feedback session & report
- A session to discuss findings, followed by a written report tailored to the referral question.
Personality assessment differs from a symptom-focused assessment (like one for anxiety or depression) in that it looks at enduring patterns across time and situations, rather than a specific, more time-limited presentation.
Who it's for
Who is a personality assessment for?
Diagnostic clarification
Including where personality disorder features (such as those associated with borderline personality disorder) are suspected and need proper assessment rather than self-diagnosis.
Understanding long-standing patterns
People wanting to understand relational or emotional patterns that have affected multiple areas of life over time.
Clinicians & treating professionals
Seeking a fuller picture to inform treatment planning.
Specific occupational contexts
Where personality assessment is a relevant, requested part of a broader evaluation.
Inclusions
What's included in a personality assessment?
Typical inclusions are the clinical interview(s), relevant standardised personality measures, a written report addressing the referral question, and a feedback session to discuss findings. The specific tools used depend heavily on the referral reason — assessing for personality disorder features looks different from a broader personality profile for self-understanding or occupational purposes. Confirm with your matched psychologist what approach fits your specific situation.
Cost
What does a personality assessment cost?
Costs vary depending on the scope of the assessment and the specific tools required.
Medicare rebates for psychological assessment are limited and depend on your individual circumstances and referral pathway; a GP can advise on what may be relevant to your situation. Because scope varies significantly by referral reason, we’d rather point you toward confirming a specific quote once your assessment need is clarified than provide a general figure here.
Before you go
How to prepare for a personality assessment
- Reflect on long-standing patterns
- Rather than recent or situational experiences, think about patterns that have shown up consistently across different periods of your life and different relationships.
- Clarify the purpose upfront
- Knowing why you’re seeking assessment — diagnostic clarity, treatment planning, self-understanding, an occupational requirement — helps your psychologist choose the right approach.
- Consider who else might contribute
- Input from someone who’s known you well over time can sometimes add useful perspective.
- Bring relevant history
- Previous mental health diagnoses, treatment history, or relevant reports, if applicable.

Common questions
Frequently asked questions
What’s the difference between a personality assessment and a general psychological assessment?
A personality assessment specifically focuses on enduring patterns in thinking, feeling, and relating to others over time, rather than a specific symptom cluster or cognitive domain. It’s often used when understanding long-standing patterns — rather than a discrete, time-limited presentation — is the central question.
Can a personality assessment diagnose a personality disorder?
Yes, a comprehensive personality assessment conducted by a psychologist can contribute to diagnosing a personality disorder, where relevant, using standardised tools and clinical judgement. This is a more involved and sensitive process than a general self-assessment or online quiz, and should be undertaken with a qualified clinician.
Do I need a referral for a personality assessment?
Not necessarily — you can generally book directly with a psychologist. A referral may be relevant if you’re seeking a Medicare rebate or if a treating professional has recommended the assessment as part of your care.
How long does a personality assessment take?
This varies depending on scope and referral reason, but is typically spread across more than one session given the depth of history and testing involved.
Will the results affect how I’m treated by future clinicians?
A personality assessment report is intended to support accurate understanding and better-informed care, not to label or limit you. A good report reflects genuine patterns and strengths, not just areas of difficulty, and should be discussed with you directly before being shared elsewhere.
Is telehealth an option for personality assessment?
Some components, such as interviews and certain questionnaires, can often be conducted via telehealth, though this depends on the specific tools used and the clinician’s approach. Confirm the format with your matched psychologist.
