“…Experimental studies showed that sleep deprivation (ranging from no sleep to maximum 4 h sleep) led to more PEs in healthy volunteers (Meyhöfer, Kumari, Hill, Petrovsky, & Ettinger, 2017; Petrovsky et al, 2014; Reeve, Emsley, Sheaves, & Freeman, 2018 a ), providing evidence for a causal relationship between sleep deprivation and PEs. Longitudinal research has shown that sleep problems are associated with later PEs in UHR youth (Lunsford-Avery, LeBourgeois, Gupta, & Mittal, 2015), the general population (Freeman et al, 2012; Reeve & Bell, 2022; Wang et al, 2023; Zhou et al, 2022) and patients diagnosed with non-affective psychotic disorder (Reeve, Nickless, Sheaves, & Freeman, 2018 b ). In addition, this relationship was found to be bidirectional in patients with non-affective psychosis (Reeve et al, 2018 b ), but not in adolescents from the general population (Zhou et al, 2022).…”

Furthermore, insomnia significantly predicted the persistence of paranoia over the course of three months in a clinical adolescents sample (Bird, Waite, Rowsell, Fergusson, & Freeman, 2017).…”

The dynamic relationship between sleep and psychotic experiences across the early stages of the psychosis continuum

Background: Psychotic disorders develop gradually along a continuum of severity. Understanding factors associated with psychosis development, such as sleep, could aid in identification of individuals at elevated risk. This study aimed to assess (1) the dynamic relationship between psychotic experiences (PEs) and sleep quality and quantity, and (2) whether this relationship differed between different clinical stages along the psychosis continuum. Methods: We used daily diary data (90 days) of individuals (N = 96) at early stages (i.e. before a first diagnosis of psychosis) along the psychosis continuum. Multilevel models were constructed with sleep quality and sleep quantity as predictors of PEs and vice versa. Post-hoc, we constructed a multilevel model with both sleep quality and quantity as predictors of PEs. In addition, we tested whether associations differed between clinical stages. Results: Within persons, poorer sleep predicted next day PEs (B = −0.02, p = 0.01), but not vice versa. Between persons, shorter sleep over the 90-day period predicted more PEs (B = −0.04, p = 0.002). Experiencing more PEs over 90-days predicted poorer (B = −0.02, p = 0.02) and shorter (B = −1.06, p = 0.008) sleep. We did not find any significant moderation effects for clinical stage. Conclusions: We found a bidirectional relationship between sleep and PEs with daily fluctuations in sleep predicting next day PEs and general patterns of more PEs predicting poorer and shorter sleep. Our results highlight the importance of assessing sleep as a risk marker in the early clinical stages for psychosis.

“…Moreover, causal associations cannot be indicated as the cross-sectional design was used. However, according to existing evidence in the field, bidirectional associations between PLEs and sleep disturbance are most likely to occur [ 19 , 22 , 23 ]. Also, all assessments were performed using self-reports with selected items derived from specific tools.…”

“…There is accumulating evidence that PLEs are associated with poor sleep quality [ 19 – 21 ]. Studies based on longitudinal designs and experience sampling methodology suggest that there might be a bidirectional association between poor sleep quality and PLEs [ 19 , 22 , 23 ]. It has also been demonstrated that cognitive-behavioral therapy of insomnia might reduce the level of paranoia and hallucinations in university students [ 24 ].…”

Psychotic-like experiences (PLEs) have been associated with poor sleep quality and increased suicide risk. However, the association between PLEs, insomnia and suicide risk has not been thoroughly investigated in prior studies. In this study, we aimed to explore as to whether insomnia moderates the association between PLEs and suicidal ideation. The study was performed in 4203 young adults (aged 18–35 years, 63.8% females). Data were collected using self-reports. Moderation analysis demonstrated that PLEs are associated with higher levels of the current suicidal ideation only in participants with greater severity of insomnia (B = 0.003, p < 0.001). This analysis included age, gender, education, occupation and depressive symptoms as covariates. Moreover, the network analysis demonstrated that nodes representing PLEs are connected to the node of current suicidal ideation only in participants with greater severity of insomnia. The nodes of PLEs connected to the current suicidal ideation node captured PLEs representing deja vu experiences, auditory hallucination-like experiences and paranoia (edge weights between 0.011 and 0.083). Furthermore, nodes representing PLEs were the three most central nodes in the network analysis of individuals with higher levels of insomnia (strength centrality between 0.96 and 1.10). In turn, the three most central nodes were represented by depressive symptoms in the network analysis of individuals with lower levels of insomnia (strength centrality between 0.67 and 0.79). Findings from this study indicate that insomnia might be an important risk factor of suicide in people with PLEs, especially those reporting deja vu experiences, auditory hallucination-like experiences and paranoia.
