However, previous studies have relied on cross-sectional designs, limiting insight into how these cognitive processes relate to sleep on a night-to-night basis. In addition, anticipatory stress has received little empirical attention, despite its relevance for poor sleep. To address these gaps, the present study examined the associations of pre-sleep cognitive arousal, pre-sleep rumination, and anticipatory stress with sleep quality, sleep duration, and sleep onset latency both when averaged across 7 days (between-person level) and on a day-to-day basis (within-person level).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 166 emerging adults (Mage\u2009=\u200920.36\u00a0years, 80.1% female) completed smartphone-based surveys during 7 consecutive days, reporting on pre-sleep cognitive processes (cognitive arousal, rumination, anticipatory stress) each evening and sleep outcomes each morning.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Linear mixed-effects models showed that, at the between-person level, higher average levels of all three pre-sleep cognitive processes across the week were associated with poorer sleep quality and shorter sleep duration. No significant associations were found for sleep onset latency. At the within-person level, all three pre-sleep cognitive processes were not related to next-morning sleep outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Overall, the findings suggest that stable individual differences in pre-sleep cognitive processes, rather than short-term changes, are linked to sleep quality and duration in emerging adults.<\/jats:p>\n                    <jats:p>Statement of Significance To clarify whether pre-sleep cognitive arousal, pre-sleep rumination, and anticipatory stress show both stable (trait-like) and night-to-night (state) variation, we examined how these pre-sleep cognitive processes relate to sleep in emerging adults. Our findings suggest that trait-like levels of all three cognitive processes are associated with poorer sleep quality and shorter sleep duration, while sleep onset latency appears unaffected. In contrast, short-term nightly changes in these processes were not related to sleep outcomes. Overall, stable pre-sleep cognitive tendencies may be more relevant for sleep than dynamic nightly fluctuations in emerging adults, with important implications for prevention and therapeutic programs.<\/jats:p>\n
