Plain English distinction
Primary and secondary psychological injury are not the same thing
A primary psychological injury is usually where the psychological condition is caused directly by workplace events, such as bullying, harassment, excessive workload, workplace violence, traumatic exposure or another direct work stressor.
A secondary psychological injury is where the psychological condition arises as a consequence of another work-related condition, commonly a physical injury. Examples include depression after chronic back pain, anxiety after failed surgery, or adjustment symptoms after losing capacity for physical work.
Why classification matters
Classification can affect the legal issues, evidence needed, insurer arguments and impairment pathway. Primary psychological injury claims often require close attention to work events, substantial or main contributing factor issues, section 11A management-action arguments and current NSW reform settings. Secondary psychological injury claims usually require careful linkage to the physical injury, pain, treatment, capacity and claim course.
Evidence focus
Primary claims usually need a workplace event chronology. Secondary claims usually need medical evidence linking physical injury consequences to psychological symptoms.
Insurer disputes
Primary claims may raise management-action arguments. Secondary claims often raise causation, personal stress or treatment-necessity arguments.
Impairment pathway
SIRA guidance distinguishes primary psychological impairment from secondary psychological conditions. Get advice before making assumptions.
Examples
Primary example
A worker develops PTSD symptoms after witnessing a traumatic event at work. The work event itself is the alleged cause of the psychological condition.
Secondary example
A worker develops depression after a back injury causes chronic pain, failed duties and loss of earning capacity. The psychological symptoms are said to follow from the physical injury consequences.
Mixed issue
A worker has a physical injury, then conflict during return to work. The file may need careful advice on whether symptoms are primary, secondary, or affected by both pathways.
Evidence issues to avoid
- Do not assume a diagnosis alone proves work connection.
- Do not mix every workplace grievance into a secondary psychological injury claim without a clear medical link.
- Do not ignore section 11A or reform-sensitive issues where direct workplace events are alleged.
- Do not assume psychological impairment can be claimed without checking whether the condition is primary or secondary.
- Do not let the insurer describe the claim as personal stress without answering the medical chronology.
Permanent impairment caution
SIRA guidance states that a secondary psychiatric or psychological condition arises as a consequence of another work-related condition, and that no permanent impairment assessment is to be made of secondary psychiatric and psychological impairments. SIRA also states that permanent impairment compensation is not available for secondary psychological injuries.
That does not mean the symptoms are irrelevant. Secondary psychological symptoms may still matter to treatment, weekly payments, work capacity, rehabilitation and work injury damages evidence. The classification should be checked before settlement or impairment strategy is assumed.
Frequently asked questions
What is the difference between primary and secondary psychological injury?
Primary psychological injury is caused directly by workplace events. Secondary psychological injury arises as a consequence of another work-related condition, often a physical injury.
Why does the distinction matter?
It can affect evidence, insurer disputes, section 11A issues, reform-sensitive arguments and permanent impairment strategy.
Can a physical injury cause depression or anxiety?
It can. Chronic pain, reduced mobility, surgery, inability to work, financial stress and long disputes may contribute to symptoms, but the evidence must support the connection.
Can secondary psychological symptoms affect weekly payments?
Yes, where the symptoms affect sustainable work capacity and are supported by medical evidence.
Can secondary psychological injury be claimed for WPI?
SIRA guidance states that permanent impairment compensation is not available for secondary psychological injuries. Get advice before assuming how this applies to your matter.
