7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about acute stress disorder and death from acute stress disorder.
Meaning of acute stress disorder
(2) For the purposes of this Statement of Principles, acute stress disorder means a disorder of mental health which meets the following criteria (derived from DSM-5-TR):
The individual is exposed to actual or threatened death, serious injury, or sexual violence in one (or more) of the following ways:
(i) directly experiencing the traumatic event(s);
(ii) witnessing, in person, the event(s) as it occurred to others;
(iii) learning that the event(s) occurred to a close family member or close friend. In cases of actual or threatened death of a family member or friend, the event(s) must have been violent or accidental; or
(iv) experiencing repeated or extreme exposure to aversive details of the traumatic event(s) (for example, first responders collecting human remains, police officers repeatedly exposed to details of child abuse). This does not apply to exposure through electronic media, television, movies, or pictures, unless this exposure is work related; and
B. The presence of nine (or more) of the following symptoms from
any of the five categories of intrusion, negative mood,
dissociation, avoidance, and arousal, beginning or worsening
after the traumatic event(s) occurred:
Intrusion Symptoms
(i) recurrent, involuntary, and intrusive distressing memories of the traumatic event(s). In children, repetitive play may occur in which themes or aspects of the traumatic event(s) are expressed;
(ii) recurrent distressing dreams in which the content and/or affect of the dream are related to the event(s). In children, there may be frightening dreams without recognisable content;
(iii) dissociative reactions (for example, flashbacks) in which the individual feels or acts as if the traumatic event(s) were recurring. (Such reactions may occur on a continuum, with the most extreme expression being a complete loss of awareness of present surroundings.) In children, trauma-specific re-enactment may occur in play;
(iv) intense or prolonged psychological distress or marked physiological reactions in response to internal or external cues that symbolise or resemble an aspect of the traumatic event(s).
Negative Mood
(i) persistent inability to experience positive emotions (for example, inability to experience happiness, satisfaction, or loving feelings).
Dissociative Symptoms
(i) an altered sense of the reality of one's surroundings or oneself (for example, seeing oneself from another's perspective, being in a daze, time slowing);
(ii) inability to remember an important aspect of the traumatic event(s) (typically due to dissociative amnesia and not to other factors such as head injury, alcohol, or drugs).
Avoidance Symptoms
(i) efforts to avoid distressing memories, thoughts, or feelings about or closely associated with the traumatic event(s);
(ii) efforts to avoid external reminders (people, places, conversations, activities, objects, situations) that arouse distressing memories, thoughts, or feelings about or closely associated with the traumatic event(s).
Arousal Symptoms
(i) sleep disturbance (for example, difficulty falling or staying asleep, restless sleep);
(ii) irritable behaviour and angry outbursts (with little or no provocation), typically expressed as verbal or physical aggression toward people or objects;
(iii) hypervigilance;
(iv) problems with concentration;
(v) exaggerated startle response; and
C. Duration of the disturbance (symptoms in Criterion 2) is 3 days to 1 month after trauma exposure. Symptoms typically begin immediately after the trauma, but persistence for at least 3 days and up to 1 month is needed to meet disorder criteria; and
D. The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning; and
E. The disturbance is not attributable to the physiological effects of a substance (for example, medication or alcohol) or another medical condition (for example, mild traumatic brain injury) and is not better explained by brief psychotic disorder.
Note: DSM-5-TR is defined in the Schedule 1 – Dictionary.
Death from acute stress disorder
(3) For the purposes of this Statement of Principles, acute stress disorder, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's acute stress disorder.
Note: terminal event is defined in the Schedule 1 – Dictionary.
8 Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical‑scientific evidence that indicates that acute stress disorder and death from acute stress disorder can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.
9 Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting acute stress disorder or death from acute stress disorder with the circumstances of a person's relevant service:
(1) experiencing a category 1A stressor within the 30 days before the clinical onset of acute stress disorder;
Note: category 1A stressor is defined in the Schedule 1 – Dictionary.
(2) experiencing a category 1B stressor within the 30 days before the clinical onset of acute stress disorder;
Note: category 1B stressor is defined in the Schedule 1 – Dictionary.
(3) having a significant other who experiences a category 1A stressor within the 30 days before the clinical onset of acute stress disorder;
Note: category 1A stressor and significant other are defined in the Schedule 1 – Dictionary.
(4) experiencing the traumatic death of a significant other within the 30 days before the clinical onset of acute stress disorder;
Note: significant other and traumatic death are defined in the Schedule 1 – Dictionary.
(5) being exposed to repeated or extreme aversive details of severe traumatic events within the 30 days before the clinical onset of acute stress disorder;
Note: being exposed to repeated or extreme aversive details of severe traumatic events is defined in the Schedule 1 – Dictionary.
(6) experiencing severe childhood abuse within the 30 days before the clinical onset of acute stress disorder;
Note: severe childhood abuse is defined in the Schedule 1 – Dictionary.
(7) inability to obtain appropriate clinical management for acute stress disorder.
10 Relationship to service
(1) The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.
(2) The factor set out in subsection 9(7) applies only to material contribution to, or aggravation of, acute stress disorder where the person's acute stress disorder was suffered or contracted before or during (but did not arise out of) the person's relevant service.
11 Factors referring to an injury or disease covered by another Statement of Principles
In this Statement of Principles:
(1) if a factor referred to in section 9 applies in relation to a person; and
(2) that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) of the VEA;
then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
