71. The potential moderating effects of sleep hygiene and stress on quality of life and schizotypy
Risk for schizophrenia (i.e., schizotypy) is associated with greater levels of stress and poorer quality of life (QOL). However, little is known about how behaviors surrounding sleep (sleep hygiene) may also contribute to reduced wellbeing. A series of hypotheses were developed prior to a secondary analysis of a dataset. There were 385 participants who completed all of the questionnaires of interest. We anticipated that higher levels of schizotypy would be correlated with a worse QOL, poor sleep hygiene, and higher levels of stress. In addition, we anticipated that sleep hygiene and stress would moderate the relationship between schizotypy and quality of life. Results showed that higher levels of schizotypy were associated with a poor sleep hygiene (r=.37, p<.01), and worse sleep hygiene was associated with higher levels of stress (rs=.25-.27, ps<.01). In our regression models, higher levels of schizotypy (β=-.37) and stress (βs=-.27) were found to be significantly predictive of a worse quality of life (ps<.01). Worse sleep hygiene (β=-.12) was also found to be significantly predictive of a worse quality of life (p<.01). Contrary to our expectations, neither stress nor sleep hygiene significantly moderated the relationship between schizotypy and quality of life. Implications and future directions will be discussed.
