Research summary
Sleep disturbance is common among individuals experiencing or at high risk from psychosis and has been suggested as a causal factor in the development of psychotic experiences. Furthermore, severity of sleep disturbance is associated with reduced overall functioning and increased risk of suicide attempts. Sleep problems have therefore emerged as an important treatment target in the context of psychosis. The literature on sleep difficulties predominantly focuses on insomnia and insufficient sleep, however, hypersomnia, daytime sleeping, and day-night reversal are all common among people with psychosis. There is both theoretical and empirical evidence to suggest that different profiles of sleep disturbance vary in terms of maintaining factors and behavioural function. As such, intervention planning for people with psychosis would be aided by understanding whether sleep-reversal and hypersomnia in the context of psychosis may be maintained by idiosyncratic behavioural functions.
People who will be eligible to participate in this study are adults who have experienced sleep reversal or problems with daytime sleeping in the last 3 years, and who have been identified as having experiences of psychosis by a care coordinator in NHS mental health services.
