What Is a Forensic Psychologist?
A Forensic Psychologist is a practitioner psychologist registered with the Health and Care Professions Council (HCPC) who specialises in applying psychological theory and methods to criminal and civil justice contexts.
In the medico-legal arena, forensic psychologists are essential for evaluating complex behavioural patterns and risk factors. Unlike psychiatrists, who focus on medical diagnosis and medication, forensic psychologists use psychometric testing and behavioural formulation to assess:

Frequently Asked Questions
A forensic psychiatrist is a medical doctor who can diagnose mental illness and prescribe medication. A forensic psychologist focuses on the psychological and behavioural aspects of the individual, using psychometric testing and behavioural formulation to understand risk, personality, and cognitive functioning. Psychologists are often preferred for detailed risk assessments and cognitive/suggestibility testing.
Yes. This is a core competency. Forensic psychologists use validated actuarial and structured professional judgment tools such as the HCR-20 (for violence), Static-99R (for sexual offending), and RSVP to provide evidence-based risk predictions and management strategies.
Psychometric testing involves standardized assessments used to measure cognitive ability (IQ), memory, personality traits, and specific psychological states like suggestibility or malingering. These tests provide objective data to support the psychologist’s clinical opinion.
Yes. While psychiatrists often lead on these assessments under the Mental Health Act, forensic psychologists are frequently instructed to evaluate the cognitive and suggestibility aspects of the Pritchard criteria, particularly where a learning disability or low IQ is suspected.
