Using occupational therapy evidence effectively in psychiatric injury matters

By Ms Antonette Owen, Team Lead Occupational Therapist, Benchmark ASSESS

Understanding the value of occupational therapy evidence

Legal matters involving psychiatric injury often turn not on whether a diagnosis exists, but on what that diagnosis means in practice. The key question is often not what condition a person has, but how that condition affects their ability to function in everyday life. Courts and decision-makers are tasked with understanding how psychological symptoms affect a person’s ability to function in daily life, engage in work, manage risk, and participate sustainably in the community.

Occupational therapy (OT) evidence is uniquely positioned to address this gap. When utilised intentionally and at the right point in a proceeding, it can materially assist in clarifying liability, informing quantum, and supporting efficient resolution.

OT evidence is particularly valuable in matters where functional impact is disputed or unclear. This includes cases involving reduced work capacity, inconsistent presentations, supervision or care needs, and questions about the sustainability of participation rather than mere theoretical ability. Too often, OT evidence is instructed late in proceedings or confined to care recommendations, limiting its strategic value. When engaged earlier, occupational therapists can provide structured, objective analysis that informs negotiations and reduces uncertainty well before matters reach a forensic impasse.

Translating symptoms into function

A key strength of occupational therapy evidence lies in what it assesses that other experts do not. While psychiatrists and psychologists appropriately focus on diagnosis, causation, and symptomatology, occupational therapists examine how those symptoms translate into real-world function.

This includes the performance of daily activities, tolerance and endurance, reliability of function over time, risk awareness, and capacity for independent living or employment. Occupational therapists rely on observation, task analysis, and clinical reasoning. This helps decision-makers understand capacity not as an abstract concept, but as a person’s demonstrated ability to function in everyday life.

The importance of a well-constructed letter of instruction

The quality and usefulness of occupational therapy evidence are heavily influenced by the letter of instruction. Generic instructions often result in reports that describe limitations without offering meaningful guidance for resolution.

Well-constructed instructions should ask the assessor to consider functional capacity over time, the consistency and sustainability of function, risks associated with increased independence, and the interaction between psychological symptoms and practical performance. Framing questions with the legal decision-making context in mind enables the occupational therapist to tailor their analysis to the issues that matter most in the proceeding.

Looking beyond care needs

Another common limitation in psychiatric injury matters is an overly narrow focus on care needs. While recommendations for domestic assistance or support services may be appropriate in some cases, an exclusive focus on care needs can unintentionally promote dependency and increase long-term costs without fully exploring opportunities for rehabilitation and greater independence.

Occupational therapists are trained to consider how routine, environment, skill development, and graded activity can support improved function and independence, often making use of compensatory strategies. Expanding the scope of inquiry beyond basic care needs allows for more balanced, realistic, and defensible recommendations that align with contemporary recovery-oriented practice.

Assessing rehabilitation potential

Rehabilitation opinions are particularly important in psychiatric injury claims, where prognosis is often complex and evolving rather than fixed. Occupational therapists are well placed to assess whether functional improvement is realistic, what barriers may affect recovery, and what supports or interventions may help improve outcomes.

This future-focused analysis assists legal practitioners and courts to distinguish between permanent incapacity and potentially modifiable functional limitations. It also provides a framework for managing expectations, supporting informed settlement discussions, and avoiding recommendations that do not meaningfully improve quality of life.

Common referral pitfalls

Despite their potential value, occupational therapy assessments are often underutilised or engaged too late in the life of a claim. Common referral errors include treating OT evidence as ancillary, restricting the scope of assessment too narrowly, or selecting assessors without sufficient mental health or medico-legal experience.

Failing to brief the occupational therapist on the forensic context or relevant legal thresholds can further limit the utility of the opinion. Avoiding these pitfalls significantly increases the likelihood that the resulting evidence will withstand scrutiny and assist decision-makers.

Selecting the right occupational therapist

Selecting the right occupational therapist is therefore critical. An effective medico-legal OT assessor should demonstrate expertise in psychiatric injury, experience with legal proceedings, and a clear understanding of expert witness obligations.

Reports should be structured, evidence-based, and transparent in their reasoning, with opinions clearly distinguished from observations. Assessors who combine clinical credibility with forensic discipline are best placed to provide opinions that are both persuasive and defensible.

Supporting better outcomes

When used effectively, occupational therapy evidence becomes more than supporting material; it becomes a practical tool for resolving uncertainty.

By translating psychiatric injury into clear, functional terms, OT assessments provide clarity where ambiguity often prevails. They help decision-makers understand not only what a person is experiencing, but how that experience affects their capacity to work, live independently, and participate in the community.

This clarity supports earlier decision-making, more informed negotiations, and outcomes that reflect both legal principles and practical reality. Encouraging thoughtful, early engagement of occupational therapy expertise in psychiatric injury matters ultimately benefits all parties by supporting proportionate, realistic, and sustainable resolutions.
