A predominant complaint of dissatisfaction with sleep quantity or quality, associated with one (or more) of the following symptoms:\n\n\n(i) difficulty initiating sleep;\n\n(ii) difficulty maintaining sleep, characterised by frequent awakenings or problems returning to sleep after awakenings; or\n\n(iii) early-morning awakening with inability to return to sleep.\n\nB. The sleep difficulty causes clinically significant distress or impairment in social, occupational, educational, academic, behavioural or other important areas of functioning.\n\nC. The sleep difficulty occurs at least three nights per week.\n\nD. The sleep difficulty is present for at least three months.\n\nE. The sleep difficulty occurs despite adequate opportunity for sleep and cannot be explained by inadequate circumstances for sleep.\n\nF. The sleep difficulty is not better explained by and does not occur exclusively during the course of another sleep-wake disorder (for example, narcolepsy, a breathing-related sleep disorder, a circadian rhythm sleep-wake disorder, a parasomnia).\n\nNote 1: This definition includes chronic insomnia disorder that is attributable to the effects of a substance (including a drug of abuse or a medication).\n\nNote 2: DSM-5 is defined in the Schedule 1 – Dictionary.\n\nDeath from chronic insomnia disorder\n\n(3) For the purposes of this Statement of Principles, chronic insomnia disorder, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's chronic insomnia disorder.\n\nNote: terminal event is defined in the Schedule 1 – Dictionary.\n\n7 Basis for determining the factors\n\nOn the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that chronic insomnia disorder and death from chronic insomnia disorder can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA.\n\nNote: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.\n\n8 Factors that must exist\n\nAt least one of the following factors must exist before it can be said that, on the balance of probabilities, chronic insomnia disorder or death from chronic insomnia disorder is connected with the circumstances of a person's relevant service:\n\n(1) having a clinically significant disorder of mental health as specified within the one year before the clinical onset of chronic insomnia disorder;\n\nNote: clinically significant disorder of mental health as specified is defined in the Schedule 1 - Dictionary. \n\n(2) experiencing a category 1A stressor within the one year before the clinical onset of chronic insomnia disorder;\n\nNote: category 1A stressor is defined in the Schedule 1 - Dictionary. \n\n(3) experiencing a category 1B stressor within the one year before the clinical onset of chronic insomnia disorder;\n\nNote: category 1B stressor is defined in the Schedule 1 - Dictionary. \n\n(4) experiencing a category 2 stressor within the one year before the clinical onset of chronic insomnia disorder;\n\nNote: category 2 stressor is defined in the Schedule 1 - Dictionary. \n\n(5) experiencing severe childhood abuse before the clinical onset of chronic insomnia disorder;

(See sections 3–4.)\n\n- It defines chronic insomnia disorder by reference to DSM‑5 diagnostic criteria (difficulty falling or staying asleep or early awakening; frequency and duration requirements; distress/impairment; and exclusion of other sleep disorders) and includes insomnia related to substances. (See section 6(2) and Schedule 1.)\n\n- It lists the specific medical, psychological and life‑event factors which, if present within stated timeframes before the clinical onset or clinical worsening of the insomnia, are sufficient evidence (on the balance of probabilities) to link the insomnia to service. Those factors include recent mental health disorders, specified traumatic stressors, severe childhood abuse, serious medical events, chronic illnesses, persistent pain, tinnitus, pregnancy, certain drug exposures (including a specified drug list and mefloquine), and inability to obtain appropriate clinical management. (See section 8 and Schedule 1.)\n\n- It treats death from chronic insomnia disorder as included where the insomnia materially contributed to the terminal event that caused death. (See section 6(3).)\n\n- It requires that any listed factor relied on must be related to the person’s relevant service. Some factors (those listed at subsections 8(14)–8(26)) are limited to cases where the insomnia existed before or during service and the service materially contributed to or aggravated it. (See section 9.)\n\n- If a listed factor refers to another injury or disease already covered by a different RMA Statement of Principles, that other Statement’s terms apply. (See section 10.)\n\n\n**Who this affects**\n\n- Primary affected persons: veterans, former or current members of the Forces lodging or defending claims for disability or death benefits under the VEA or MRCA where chronic insomnia disorder is claimed (or where death is alleged to have been contributed to by insomnia). (Sections 4, 6.)\n\n- Decision-makers and administrators: DVA (or relevant claims authorities) who determine entitlement using RMA Statements of Principles, and medical practitioners who provide diagnostic and causal evidence to support claims.\n\n\n**Why it matters (practical consequences and decision mechanics)**\n\n- This Statement of Principles fixes which kinds of evidence and time relationships will usually be sufficient to conclude that a veteran’s chronic insomnia disorder is connected to their service. That changes how claims are assessed: instead of a free-form causation inquiry, decision-makers apply the specified factors and timeframes (sections 7–9).\n\n- Claimants benefit if they can show one or more listed factors within the stated timing rules; the State (through DVA/MRCA programs) bears the fiscal cost of successful claims.\n\n- Practically, the instrument shapes what medical records and histories claimants and treating clinicians must produce: clear DSM‑5 diagnosis, dates of clinical onset/worsening, and documentation of any listed stressors, drug exposures, medical events, pain, tinnitus, pregnancy or lack of access to care.\n\n\n**Testing the instrument’s stated purpose against implementation realities (costs, incentives, trade‑offs, risks)**\n\n- Fiscal and distributional effect: benefits are concentrated to successful claimants; the fiscal cost is spread across the government’s veterans’ compensation programs. (Sections 7–8 set the causal standards that produce successful claims.)\n\n- Compliance and evidentiary burden: the time-limited windows (for example, mental health or stressor within one year before onset/worsening; drug taken continuously for at least seven days with last dose within 30 days; mefloquine within two months; persistent pain or tinnitus for at least three months) create precise documentary requirements. Claimants must supply dated clinical records or other contemporaneous evidence to meet those windows. (See section 8 and Schedule 1.)\n\n- Administrative discretion and medical judgement: the RMA prescribes medical criteria but application requires clinical judgment (e.g. establishing clinical onset/worsening dates, whether a drug “is capable of producing a prominent and severe disturbance in sleep” in an individual, or whether appropriate clinical management was obtainable). Those judgements create implementation risk and may increase appeals or requests for independent medical opinion. (See sections 6(2), 8(12), 8(24), 8(26).)\n\n- Interaction with other conditions: factors that refer to other injuries or diseases are governed by the separate Statements of Principles for those conditions, producing cross-references and potential complexity in multi-morbidity cases. (See section 10.)\n\n- Incentives for behaviour: claimants and clinicians are likely to document things more precisely (dates of symptoms, drug courses, exposure to stressors) to meet the listed thresholds. Employers and insurers outside the veterans’ system are not directly regulated by this instrument; effects on private enterprise (productivity, hiring) are indirect and follow from how many veterans receive benefits and return to work.\n\n\n**Other practical points (specific mechanics to watch in a claim)**\n\n- The instrument differentiates \"onset\" and \"worsening\"; some factors apply to either, others only to worsening where the insomnia pre‑dated service. This affects whether service is a cause of new insomnia or a material aggravating factor. (See section 9(2) and subsections 8(14)–8(26).)\n\n- The defined categories of traumatic stressors are detailed (category 1A, 1B, 2) and carry different examples which determine whether an event qualifies. (See Schedule 1.)\n\n- The specified list of drugs is extensive (includes benzodiazepines, opioids, SSRIs, corticosteroids, beta‑blockers, etc.) and exposure rules are strict (continuous use for seven days, last dose within 30 days). Mefloquine has a separate two‑month window. (See Schedule 1 and subsections 8(11)–8(13), 8(23)–8(25).)\n\n\n**Bottom line**\n\n- The RMA instrument does not itself create entitlements but prescribes the medical nexus rules that claims assessors must use to decide whether chronic insomnia disorder (or death to which it contributed) is connected to relevant military service. It narrows the medical inquiry to a list of defined factors and precise timing rules, which reduces some ambiguity for decision-makers but shifts burdens onto claimants and clinicians to document diagnoses, dates and exposures in a way that fits the instrument’s timeframes.
