About the Assessment
What the Assessment Is
The Relationship Trust Assessment is a structured self-report instrument developed through Credibility Systems — an assessment and research platform distinct from the Centre for Forensic Neuroscience. It is designed for individual, private use by anyone experiencing uncertainty or a breakdown of trust within a relationship.
The assessment is not a diagnostic instrument. It does not generate clinical findings, forensic conclusions, or any form of deception determination. It is a reflective tool — a structured way to consider the degree and nature of the trust concerns you are experiencing.
Areas the Assessment Explores
Relationship Trust Strain
The overall sense that trust within the relationship has deteriorated or feels uncertain.
Uncertainty
Persistent doubt or ambiguity about a partner's behaviour, intentions, or explanations.
Perceived Inconsistencies
The degree to which explanations or accounts seem difficult to reconcile.
Communication & Boundaries
How openly information is shared between partners, and whether relationship boundaries feel intact.
Contextual Factors
Factors that may influence how relationship concerns are interpreted, including prior experiences and individual differences.
Concerns About Possible Concealment
The subjective experience of feeling that relevant information may be being withheld — without determining whether this is the case.
Important Limitations
What the Assessment Cannot Tell You
These limitations are fundamental to the responsible use of any self-report measure of this kind.
The assessment cannot determine:
No score or result from this questionnaire should be taken as establishing any of the following.
- Whether infidelity occurred
- Whether a partner is lying or being deceptive
- Whether somebody is actively concealing information
- Whether a particular allegation is true or false
- Whether a polygraph examination is or is not appropriate in your situation
Why elevated concern scores require careful interpretation
Elevated levels of trust concern can arise for a wide range of reasons unrelated to a partner's behaviour. These include communication difficulties, previous experiences of betrayal in this or prior relationships, relationship history, general uncertainty, and individual differences in how people experience and process trust.
A high score reflects the intensity of your subjective concern — not any objective determination about a partner's conduct. It is a starting point for reflection, not a conclusion.
Privacy
Your answers remain private
These are the factual privacy characteristics of how the questionnaire operates:
No registration required
You do not need to provide an email address, name, or any personal details to begin or complete the assessment.
Processed locally in your browser
Questionnaire answers are processed within your browser. Your individual responses are not sent to the Centre for Forensic Neuroscience.
Responses disappear on exit
Leaving or refreshing the assessment page removes your responses. No persistent record is retained.
You control what you share
If you later choose to contact the Centre about a specific concern, you decide what information you provide. The assessment is not part of that conversation unless you choose to raise it.
Your answers will never be sent to the Centre for Forensic Neuroscience.
After the Assessment
What happens after the assessment?
Many people will use this assessment simply as a tool for personal reflection. Understanding the nature and extent of your concerns — rather than remaining in generalised uncertainty — can itself be a useful step.
Others may find that the assessment helps them to identify whether their concern relates to a clearly defined factual question or to a broader pattern of trust difficulty.
If your concern relates to a specific disputed event
Some relationship difficulties concern general uncertainty or a gradual loss of trust. Others concern a clearly defined factual issue where one person asserts that something did or did not occur.
Where there is a specific unresolved factual issue, the Centre for Forensic Neuroscience can consider whether a structured professional credibility assessment may be appropriate. This involves a careful suitability review — it is not a service that can be applied automatically.
Suitability is assessed individually. The existence of trust concerns, however significant, does not automatically make a polygraph examination appropriate.
General Trust Difficulty
Characterised by persistent uncertainty, communication breakdown, or a gradual erosion of confidence in the relationship — without a single clearly defined disputed event. These concerns are real and may benefit from professional relationship support, but they do not typically lend themselves to a structured forensic credibility assessment.
A Specific Unresolved Factual Issue
Where there is a clearly defined disputed event — something that either did or did not occur — it may be possible to formulate a structured examination around that specific issue. Learn more about how polygraph questions are formulated and what is required for an examination to be suitable.
Professional Approach
When a polygraph examination may not be appropriate
A polygraph examination should not be approached as a general relationship reassurance tool or as a means of managing ongoing suspicion. It is a structured forensic procedure designed for specific, clearly defined factual questions — and its suitability is assessed individually in every case.
Where trust has broken down, a polygraph examination is not automatically appropriate simply because uncertainty exists. The Centre for Forensic Neuroscience operates a careful suitability process to ensure that any examination conducted is appropriate, proportionate, and ethically sound.
