What looked like a straightforward injury claim is suddenly another year away from resolution.
Psychological claims often take longer because the condition, its causes and its likely outcome cannot always be established at a single examination. The delay is not necessarily evidence of poor case management. It often reflects the difficulty of turning a changing human response into a concluded medico-legal opinion.
The injury may not be recognised at the outset.
Physical injuries usually announce themselves early. A fracture appears on imaging. A wound is treated. Restricted movement is recorded.
Psychological symptoms may emerge less clearly. The claimant initially reports pain and sleep disturbance but says little about mood, fear or intrusive memories. They may regard travel anxiety as normal after a collision or assume that their distress will settle without treatment. Only later does the functional effect become apparent. The claimant has stopped driving, avoids the place of the accident, becomes irritable at home or cannot tolerate the environment in which the injury occurred.
Delayed reporting does not prove delayed onset, and neither automatically proves causation. The expert must establish when the symptoms began, when they became clinically significant and why they were not recorded earlier. NICE recognises that trauma-related conditions can include re-experiencing, avoidance, hyperarousal, disturbed sleep, emotional numbing and functional impairment. Some symptoms may improve naturally, while others persist or become more apparent over time.
That chronology takes time to assemble.
Diagnosis is rarely the only question.
Solicitors sometimes seek a psychological report as though the task were simply to provide a diagnostic label. It is not, the expert must consider whether the claimant has a recognised disorder, a subthreshold presentation or understandable distress that does not amount to psychiatric injury. Anxiety, depression, adjustment disorder, post-traumatic stress disorder, specific phobia and psychological responses to chronic pain can share several features.
The expert must then address causation. Did the accident produce a new condition? Did it aggravate an existing disorder? Did it trigger a recurrence that would otherwise have remained dormant? Are unrelated events responsible for part of the presentation?
A claimant may have faced bereavement, employment difficulties, financial pressure, relationship problems or earlier trauma during the same period. Those events do not automatically break the causal connection with the accident. They do, however, require proper analysis. The report may need separate opinions based on competing factual histories. Current guidance for civil experts requires them to distinguish facts from assumptions and, where material facts are disputed, consider the relevant alternative factual scenarios rather than quietly deciding which witness is correct.
Earlier records become more important.
A psychological opinion is rarely safe when based only on the claimant’s account at examination. GP records, counselling notes, occupational health material, employment records and earlier medico-legal reports may all be relevant. Records from before the accident can be particularly important where there is a history of anxiety, depression, medication, trauma or work-related stress.
Obtaining these records may take months. Once received, they may create further enquiries rather than provide an immediate answer. An expert may discover an earlier episode that the claimant did not mention. There may be a gap in treatment, inconsistent descriptions of onset or evidence that symptoms worsened after an unrelated event. Conversely, earlier records may confirm good functioning before the accident despite a remote psychiatric history.
The expert must consider material that supports the opinion and material that weakens it. Practice Direction 35 requires expert evidence to be independent and objective, and the GMC requires medical experts to give impartial evidence within their competence and explain the limits of their conclusions and a report produced before the records are complete may simply need to be rewritten later.
Pain and psychological symptoms move together.
Psychological claims often accompany ongoing physical symptoms, particularly chronic pain.
Pain can disturb sleep, reduce activity, threaten employment and increase dependence upon others. Anxiety may heighten attention to bodily sensations and reinforce avoidance. Depression can reduce motivation to participate in rehabilitation. The resulting disability cannot always be divided neatly into a physical component and a psychological component.
Longitudinal research following injury has found relationships between anxiety, pain and later function. Psychiatric symptoms may contribute to continuing disability even where the original physical injury has stabilised. This creates difficulty for prognosis. The psychologist or psychiatrist may need an updated physical opinion. The physical expert may, in turn, defer part of the functional prognosis to the psychological expert.
Where several disciplines are involved, reports must be obtained in a sensible order. Joint discussions, written questions and supplementary reports may then be required to resolve differences.
Treatment changes the evidence.
A final prognosis should not always be given before reasonable treatment has been attempted.
NICE recommends recognised psychological interventions for clinically important trauma-related symptoms, including trauma-focused cognitive behavioural therapy and, in appropriate circumstances, eye movement desensitisation and reprocessing. Treatment planning must take account of symptom severity, comorbidity, engagement and the claimant’s circumstances.
An expert may recommend treatment followed by reassessment. That protects against an unnecessarily pessimistic prognosis, but it delays settlement.
The outcome is not always clear even after treatment. Some claimants improve considerably. Others attend inconsistently, find the treatment unsuitable or continue to experience symptoms despite proper engagement. The expert may then need to decide whether further improvement is likely, whether another intervention is reasonable and whether the remaining symptoms are permanent.
The parties may be reluctant to settle while treatment could materially alter general damages, future care, earnings or disadvantage on the labour market.
Function is harder to measure.
A scan can confirm a fracture. There is no equivalent image showing the extent to which anxiety prevents a claimant from working, travelling or socialising.
Psychological assessment depends upon clinical interview, observed presentation, the records, functional history and, where appropriate, validated measures. Each source has limitations.
Questionnaire scores are not diagnoses. Presentation during one appointment may not reflect functioning over several months. Relatives may provide useful evidence but may also have incomplete knowledge. Employment records can show absence without explaining its cause.
Disputes often arise where the claimed disability appears inconsistent with other evidence. The claimant may report being unable to travel but has taken a holiday. They may describe severe social withdrawal while maintaining an active online life. Such evidence may be relevant, but it rarely interprets itself.
The expert should explain the clinical significance of any inconsistency without assuming the court’s role. Genuine injury, variable function and exaggeration can exist together. Determining which explanation best fits the whole evidence takes longer than accepting or rejecting the claimant’s account at face value.
Procedure adds further stages.
Civil procedure restricts expert evidence to that which is required. Permission may be needed for psychiatric or psychological evidence, particularly where another medical expert has already commented on minor symptoms. Once obtained, the report may lead to written questions under Part 35, a report from the opposing party’s expert and an experts’ discussion.
The claim may also change value as the evidence develops. A modest physical injury claim can become more complex if psychological symptoms affect employment, care needs or long-term independence.
The Pre-Action Protocol encourages the early exchange of information, rehabilitation and settlement without proceedings. Early action can shorten the claim, but only where the psychological difficulty is recognised and addressed rather than left until the physical evidence is complete.
Psychological claims take longer because the expert is being asked to explain more than a diagnosis. The opinion must connect symptoms to an event, separate competing causes, assess function, consider treatment and predict an outcome that may still be changing.
The answer is not to rush the evidence. It is to identify the psychological issue earlier, obtain the right records and ask the right expert the right questions.
A late psychiatric instruction does not make a complex claim simple. It merely begins the difficult work later.
