Assessment, formulation and risk: what each means—and what it cannot tell us

Assessment, formulation and risk assessment are related, but they are not interchangeable. Understanding the difference helps clinicians work within competence, communicate responsibly and decide when specialist forensic input is needed.

A clinical assessment is not automatically a risk assessment, and a risk score is not a complete formulation. Each serves a different purpose. Confusing them can lead to overconfidence, vague reports or decisions that are not adequately linked to evidence.

Assessment begins with the question

A good assessment is designed around its purpose. A therapist deciding whether a person is suitable for treatment is asking a different question from a court considering expert evidence, a probation practitioner reviewing risk management, or a multidisciplinary team planning care.

Assessment may include interviews, records, psychometric measures, collateral information, behavioural history, current circumstances and discussion with other professionals. The relevance and weight of each source depend on the question being asked. Important information may be incomplete, disputed or unavailable, and those limitations should be made explicit.

The Health and Care Professions Council expects practitioner psychologists to use structured assessment methods relevant to their domain, critically evaluate risks and recognise the limits of practice. These principles are valuable beyond psychology: professionals should be clear about what they have assessed, why, and whether the work falls within their training and role.

Formulation is an explanatory hypothesis

Formulation organises information into a meaningful account of the individual rather than simply listing problems or factors. It may explore the development and function of behaviour, patterns and triggers, relationships, beliefs, emotional regulation, opportunity, social context, strengths, protective factors and the conditions associated with change.

A formulation is not a declaration of certainty. It is a professional hypothesis that should be transparent, evidence-informed and open to revision when new information emerges. It can guide treatment priorities, identify gaps in understanding and help different professionals communicate. It should also distinguish clearly between known facts, reported information, professional interpretation and unresolved questions.

Explanation is not exoneration. Understanding how harmful behaviour developed or was maintained does not remove responsibility or determine a legal issue. A formulation should support clearer thinking about intervention and management without minimising harm.

Risk assessment is specific, contextual and time-limited

“Is this person a risk?” is too broad to be a sound assessment question. Risk assessment should identify the outcome being considered, to whom, under what circumstances, over what period and for which decision. The same person may present different concerns in different contexts, and those concerns may change with treatment, supervision, opportunity, relationships, health or other circumstances.

The Risk Management Authority describes good risk assessment as evidence-based and structured, drawing on multiple sources, appropriate tools and professional decision-making. It places narrative formulation at the centre of understanding the onset, development, occurrence and maintenance of harmful behaviour, and links this understanding to possible future scenarios and risk management.

Risk assessment is therefore more than producing a score. Where actuarial or structured tools are used, they can contribute empirical structure and consistency, but they must be appropriate to the population, outcome and setting for which they were developed. Their limitations, missing information and uncertainty remain part of the assessment.

Prediction has limits

No instrument or clinician can predict an individual’s future with certainty. Statistical estimates are derived from groups and do not become guarantees when applied to one person. Results can vary across samples and settings, and the significance of a finding depends on factors including the comparison group, follow-up period, outcome definition and quality of the available data.

Research on sexual-recidivism tools illustrates both their value and their limits. Structured instruments may assist with classification and further assessment, but validation studies do not show perfect prediction. Absolute rates can vary between samples, and a tool designed for one population or outcome should not be extended to another without evidence.

Responsible communication avoids labels that imply permanence. It describes the nature, pattern, seriousness, likelihood and possible imminence of the specified behaviour, the circumstances in which concern may rise or fall, protective factors, and the practical implications for management. It also states what cannot be concluded.

What this means for therapists

Therapists routinely assess need, suitability, safeguarding, therapeutic goals and change. They may develop treatment formulations and notice factors relevant to risk. This does not automatically qualify a therapist to provide a formal forensic risk opinion for a court, parole process, employer or statutory agency.

Formal risk work may require specialist training, competence in particular instruments, access to verified records, knowledge of the relevant legal and operational context, independent reasoning, appropriate supervision and the ability to defend conclusions under scrutiny. A treating therapist may also hold a different role from an independent evaluator.

When a concern moves beyond a practitioner’s competence or remit, good practice includes seeking specialist consultation, discussing the limits of the work, following safeguarding and information-sharing duties, and referring when necessary. Immediate concerns about danger or safeguarding require the relevant statutory or emergency pathway—not an informal attempt to calculate risk.

The aim is better decisions, not greater certainty

High-quality forensic practice does not eliminate uncertainty. It makes the reasoning visible, tests alternative explanations, uses appropriate evidence and links conclusions to proportionate decisions. Assessment provides the information, formulation provides an explanatory framework, and risk assessment applies both to a clearly defined future concern.

Keeping these tasks distinct protects clients, practitioners, decision-makers and those who may be affected by harm. It also makes collaboration more useful: each professional can contribute within their role without presenting a partial perspective as a complete answer.
