Abstract
The co-occurrence of sleep disruption and schizophrenia-spectrum symptomology is common, with current research supporting the use of interventions, such as cognitive behavioral therapy for insomnia (CBTi), which include sleep hygiene education. Sleep hygiene refers to patterns of pre-sleep behaviors that can promote or impair sleep. These behaviors are easily identified and modifiable, potentially holding promise as targets of research and clinical practice. However, there is little research examining sleep hygiene in those at-risk for schizophrenia, measured through clusters of sub-clinical symptoms known as schizotypy. Given the likelihood poor sleep exacerbates negative emotions, thus serving as an etiologically relevant stressor, the study of sleep hygiene in at-risk populations appears warranted. Additionally, quality of life (QOL) has previously been shown to be negatively associated with sleep hygiene and schizophrenia-spectrum risk. As such, QOL domains were included to quantify the extent pre-sleep habits and dimensional schizotypy impact individuals’ wellbeing. Data was collected from a non-clinical sample of 385 young adults (M = 20.83, SD = 3.61). As anticipated, higher schizotypy was correlated with poorer sleep hygiene and reduced QOL, although only negative schizotypy predicted QOL in the final regression model controlling for sex differences. Sex differences were present for all variables of interest except disorganized schizotypy. Post-hoc item-level analyses suggested that higher levels of schizotypy were correlated with emotional rumination prior to sleep, while increased negative schizotypy was associated with reduced QOL. Future research should further evaluate sleep hygiene as a potentially relevant risk variable in the development of schizophrenia-spectrum symptomology and associated decline in QOL.
