Meaning of chronic insomnia disorder
(2)          For the purposes of this Statement of Principles, chronic insomnia disorder means a persistent disorder of sleep that meets the following diagnostic criteria (derived from DSM-5):
             1. A predominant complaint of dissatisfaction with sleep quantity or quality, associated with one (or more) of the following symptoms:
                (i)            difficulty initiating sleep;
                (ii)         difficulty maintaining sleep, characterised by frequent awakenings or problems returning to sleep after awakenings; or
                (iii)       early-morning awakening with inability to return to sleep.
            B.            The sleep difficulty causes clinically significant distress or impairment in social, occupational, educational, academic, behavioural or other important areas of functioning.
            C.            The sleep difficulty occurs at least three nights per week.
            D.           The sleep difficulty is present for at least three months.
            E.            The sleep difficulty occurs despite adequate opportunity for sleep and cannot be explained by inadequate circumstances for sleep.
            F.             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).
             Note 1:  This definition includes chronic insomnia disorder that is attributable to the effects of a substance (including a drug of abuse or a medication).
