Brief description

Adjustment disorder is a condition involving the development of emotional and behavioural symptoms in response to an identifiable one-off, recurrent or ongoing stressor(s), and which meets the DSM-5-TR diagnostic criteria. Part of the criteria is that the adjustment disorder must occur within 3 months of the onset of the stressor(s) and once the stressor or its consequences have terminated, the symptoms do not persist for more than an additional 6 months. 

Confirming the diagnosis

This diagnosis needs to be established by a psychiatrist.

Clinical onset

Clinical onset must be within 3 months of the occurrence of the relevant stressor(s).

Clinical worsening

The only SoP worsening factor is for inability to obtain appropriate clinical management.  Given the nature of the condition, permanent worsening beyond the normal course is unlikely.  Specialist psychiatrist opinion would be required to establish that such worsening had occurred.
