" FRAMEWORK: This is a collaborative project between the researchers of the UR2NF of the Université Libre de Bruxelles (ULB) and the Institute of Psychology of the Eötvös Loránd University of Budapest (ELTE). AIMS: To examine the bidirectional relationship between subjectively assessed sleep quality and daytime functioning with a special emphasis on the interplay between altered patterns of sleep timing, duration, and quality and daytime behavior, cognition, and affect during a 2- week long confinement period amidst the Covid-19 pandemic in Europe. PROCEDURE: Phase 1: Cross-sectional, on-line questionnaire assessing trait-like measures of Cognitive Disorganization, PTSD-like symptoms, and depression. Phase 2: Selected participants will receive questionnaires twice a day (morning, late afternoon) for 2 weeks. SPECIFIC HYPOTHESES: Subjective sleep disruption (assessed in the morning) will be associated with increased rumination, negative affect, psychotic-like experiences, and somatic symptoms the following day. Wake-like dysfunctions (rumination, negative affect, and psychotic-like experiences) will be associated with disrupted sleep quality the night that follows. More variable sleep-wake timing (circadian disruption) and variability in sleep quality (instability of sleep quality) will be associated with impaired daytime functioning in the two-week study period. Higher mismatch between circadian-preferences and sleep-wake schedules will be associated with poorer sleep quality and more negative daytime functions in the two -week study period. This study is currently running, a brief summary of the preliminary results of our analyses will be posted here in due time. "
