Polygraph Test in Tarragona

Polygraph Tests in Tarragona: Professional Assessments in the City Centre
Tarragona is home to business, logistics, industrial and service-sector activity, with professional and family connections extending to Reus, Vila-seca, Salou and the wider Camp de Tarragona. INTERPOLYS handles enquiries concerning relationships, suspected theft, workplace disputes and specific events requiring clarification. Each request is assessed to establish whether a psychophysiological examination is appropriate.
The assessment begins with a pre-test interview, followed by a review and preparation of the questions. Where the case is suitable, physiological responses are recorded. A polygraph does not directly detect lies: the recordings require specialist interpretation and the findings must be understood within the limitations of the method.
In-person appointments are scheduled only after confirmation. A possible venue is a temporarily rented professional office at Via de l’Imperi Romà, 11, 43003 Tarragona, subject to the provider’s availability and authorisation for this use. This is not a permanent INTERPOLYS office. We will confirm the final location before you travel.

Polygraph Methodology, Pre-Test Interview & Technical Analysis
A polygraph records changes in physiological activity during a sequence of questions. These recordings are not, in themselves, direct evidence of deception: they require an established protocol, suitable conditions and specialist interpretation.
INTERPOLYS prepares every assessment by reviewing the case, confirming consent, drafting questions and analysing the recordings afterwards. The European Polygraph Association (EPA) and the American Polygraph Association (APA) publish professional guidance and standards for the field.
The stated accuracy of up to 98% depends on the methodology, the suitability of the case and the examination conditions; it is not a guarantee for an individual examination. The findings should be considered alongside other available information.

Professional Polygraph Equipment and Suitable Examination Conditions in Tarragona
Careful question preparation, privacy during the session and professional analysis of the recordings are essential. The technology records physiological responses but cannot, on its own, establish whether a statement is true.


How a Polygraph Test in Tarragona Works
Four stages for assessing a clearly defined matter: initial case review, pre-test interview, physiological recording and analysis of the results.
Initial Case Enquiry
Explain what happened, the approximate dates and what you would like to clarify. We will assess whether the matter is suitable for a polygraph examination.
Interview & Preparation
The examiner listens to the person being tested, clarifies the facts, explains consent and reviews the wording of every question.
Polygraph Examination
Sensors are fitted and physiological responses are recorded during the question sequences in accordance with the selected protocol.
Analysis of Results
The recordings undergo a technical review, and the findings, scope and limitations are explained. Documentation depends on the service booked.
