“…Specifically, polysomnography (PSG), actigraphy, and subjective sleep quality assessments indicate increased sleep latency and awakenings during the sleep period, shifted wake/ sleep periods, increased naps, and reduced sleep efficiency in schizophrenia [5,6]. Disturbed sleep occurs in the prodromal phase [7], commonly precedes psychotic exacerbation [8], and occurs in both antipsychotic medicated and unmedicated states [9,10].…”

Up to 80 % of individuals with schizophrenia spectrum disorders experience sleep disturbances, which impact physical and mental health, as well as quality of life. In this paper, we review and integrate emerging literature, published between 2012 and 2014, regarding approaches to diagnosis and treatment of major sleep disorders for people with schizophrenia spectrum disorders, including insomnia, obstructive sleep apnea (OSA), circadian rhythm dysfunction, and restless legs syndrome (RLS). We advocate for (1) the need to evaluate the utility of nonpharmacological approaches in people with schizophrenia spectrum disorders; (2) documentation of guidelines to assist providers in clinically tailoring such interventions when their clients experience positive, negative, and/or cognitive symptoms; (3) research on the best ways providers can capitalize on clients' self-identified needs and motivation to engage in sleep treatments through shared decision making; and (4) the importance of investigating whether and how mental health and sleep treatment services should be better connected to facilitate access for people with schizophrenia spectrum disorders. Assessment and tailored treatment of sleep disorders within mental health treatment settings has the potential to reduce sleep problems and improve functioning, quality of life, and recovery of this population.

“…Individuals' experience of sleep is subjective, 9 and the literature demonstrates a discrepancy between sleep satisfaction indicators when using validated self-report questionnaires and simply asking users of mental health services, with service users reporting lower rates of diffi culties than empirical measures. 4 Using a service-specifi c self-report sleep questionnaire, Poulin et al 10 found that individuals with a diagnosis of schizophrenia were more likely to describe sleep-onset insomnia, yet reported normal sleep satisfaction when compared with healthy controls. It is suggested that such discrepancies in perceived need may have a signifi cant impact on engagement in insomnia-related treatment.…”

Study Objectives: Poor sleep quality, particularly insomnia, has been identifi ed as a frequent problem among individuals with mental health diffi culties. Comorbid sleep diffi culties adversely affect quality of life and functioning, and have been associated with the causation and maintenance of a number of psychiatric disorders, as well as increasing the risk of relapse. The study objectives were to ascertain clinician knowledge related to insomnia, investigate sleep quality among service users in a community mental health setting in the UK, and evaluate service provision of evidence-based interventions for sleep diffi culties. Methods: A cross-sectional design was used. Nineteen clinicians completed a questionnaire on their clinical practice. Seventy-three service users completed the Pittsburgh Sleep Quality Index and provided self-report data on interventions received and associated satisfaction. Results: Clinical staff demonstrated defi cits in knowledge of insomnia symptomatology. Sixty-four percent (95% CI 54% to 74%) of service users were identifi ed as poor sleepers on the PSQI. Sixty-one percent of poor sleepers had not been offered support for sleep diffi culties. The most common support received was prescribed psychotropic medication (32%). Cognitive behavioral therapy was the intervention rated as most helpful but was only received by 6%. Conclusions: This study highlights inadequacies in providing evidence-based interventions for sleep diffi culties. Key recommendations include training clinicians in the identifi cation of sleep diffi culties and provision of evidencebased interventions, provision of cost-effective transdiagnostic group interventions, and formalizing assessment and treatment pathways for service users with sleep diffi culties.

“…[5,7]. The evidence also suggests that reduced sleep duration is more commonly reported in neuroleptic-naive or drug-free individuals, while a longer need for sleep is reported in medicated samples [4,8], consistent with drug studies demonstrating the sedative properties of antipsychotic medication. Investigations of circadian rhythm chronobiologic parameters in SZ also point to disruptions in the internal biological clock of patients, showing dysregulation of the suprachiasmatic nucleus (SCN) and abnormal levels of melatonin [9][10][11][12].…”

“…Clinical observations, subjective reports, and questionnaire studies have been remarkably consistent in showing difficulties falling sleep ("increased sleep latency"), sleep interruptions, and longer need for sleep [4][5][6] in SZ. Indeed, studies suggest that approximately 50% -70% of individuals with SZ experience insomnia [6].…”
