Evidence on the relation between binge-watching and sleep quality is still scarce and inconsistent and none has taken into account both the healthy and pathological dimensions of the phenomenon. This study aimed at filling this gap by investigating both aspects in healthy participants with high and low sleep quality. Further, we aimed at identifying sociodemographic, psychological and sleep-related determinants of problematic binge-watching in poor sleepers. We first conducted independent comparisons between good (n = 253) and poor sleepers (n = 209) on different binge-watching symptoms and motives, assessed through ‘Binge-watching Engagement and Symptoms’ and ‘Watching TV Series Motives’ questionnaires, respectively. Then, we focused on the problematic aspects of binge-watching in poor sleepers, investigating the role of emotion regulation, loneliness, and sleep-related factors using hierarchical multiple regressions. Comparisons between the two groups revealed a greater extent of binge-watching behaviour (t = −2.80, p = 0.005) and greater use of this practise to cope with negative emotions (t = −4.17, p < 0.001) in poor sleepers. In addition, hierarchical multiple regressions showed that gender (β = −0.166, p = 0.008), alcohol consumption (β = −0.135, p = 0.035), emotional dysregulation (β = 0.260, p = 0.001; β = 0.298, p < 0.001), feelings of loneliness (β = 0.159, p = 0.029; β = 0.199, p = 0.003), and daytime sleepiness (β = 0.149, p = 0.016) are significant determinants of problematic binge-watching in this population. In addition to showing for the first time the relationship between sleep quality and different aspects of binge-watching, our findings indicate that emotional dysregulation, feelings of loneliness, and daytime sleepiness play a key role in determining problematic binge-watching in poor sleepers, possibly due to the existence of a pathological vicious circle between these factors in poor sleepers.

Starting from the idea that dreaming could be considered an index of the psychological health of individuals regarding the COVID-19 outbreak, a major risk of psychological maladjustment has been registered formaladaptive daydreamers (MDers; i.e., people with a compulsive fantasy activity associated with distress and psychological impairment). Nevertheless, there is a gap in literature about dreaming inMDers in general and particularly during the COVID-19 pandemic. The aim of this study was to investigate differences in dreaming and dream content between probableMDers and non-MDers during the COVID-19 lockdown in Italy. A total of 3,857 Italian adults (664 probable MDers), completed the Maladaptive Daydreaming Scale (MDS-16) and the Mannheim Dream Questionnaire (MADRE). Among them, 1,095 participants (222 probable MDers) decided to recount their dreams, subsequently analysed through a cluster analysis performed by T-LAB software. Significantly higher levels of dream recall, emotional intensity of dreams, nightmare frequency, nightmare distress, recurring nightmares about daytime, lucid dreams, interest toward dreams, problem solving and creative dreams, and dreams affecting daytime mood emerged in probableMDers compared to non-MDers. No differences were observed in the emotional tone of dreams. From the quali–quantitative analysis of dream narratives, similar themes emerged in probable MDers and non-MDers, except for a cluster named Dreaming the loss of others, where the non-MDers variable is highly represented. Our results highlight some significant differences between probable MDers and non-MDers with respect to dreaming activity. The massive use of dream activity as an affective regulator emerges for both probable MDers and non-MDers during lockdown.

: The psychological consequences of COVID-19 pandemic may include the activation of stress systems, that involve the hypothalamic-pituitary-adrenal axis which influences many physiological functions, including sleep. Despite epidemiological studies evidenced greater prevalence of stress symptoms and sleep disturbances during COVID-19, longitudinal evidence investigating the effects of stress on sleep disturbances during the pandemic is lacking. We collected measures of perceived stress and sleep disturbances during the first wave of COVID-19 (March 2020) and at 8-10 months follow up in a sample of 648 adults (M= 33.52, SD= 12.98 years). Results showed that 39.4% of participants reported moderate to extremely severe stress in March 2020. Prevalence of sleep disturbances was 54.8% in March 2020 and 57.4% at follow-up. Structural equation modelling highlighted that perceived stress in March 2020 significantly predicted sleep disturbances at follow up (β=0.203; p<0.001), even after controlling for baseline sleep disturbances. Results remained significant even after controlling for the effects of covariates including age, sex, depression and anxiety symptoms, and referring to psychological services (β=0.179; p<0.05). Findings confirm the high prevalence of stress symptoms during the COVID-19 pandemic and provide first longitudinal evidence for the effects of perceived stress on sleep disturbances during the pandemic.

Recent literature shows that the Coronovirus-19 (COVID-19) pandemic has provoked significant changes in dreaming. The current study intends to provide an update about dream variable changes during the second wave of COVID-19. A total of 611 participants completed a web survey from December 2020 to January 2021. Statistical comparisons showed that subjects had lower dream-recall frequency, nightmare frequency, lucid-dream frequency, emotional intensity, and nightmare distress during the second than the first wave of the pandemic. Dreams had a higher negative tone during the second than first wave. We revealed significant differences concerning post-traumatic growth, sleep-related post-traumatic stress disorder (PTSD) symptoms and sleep measures between groups obtained as a function of the changes in the oneiric frequency between the first and second waves. We also found significant correlations between qualitative/emotional dream features and COVID-19-related factors (job change, forced quarantine, having COVID-19 infected relatives/friends, or asking for mental health help). Overall, we found that the second wave affected fewer quantitative features of dream activity and there was less emotional intensity. Moreover, we confirmed the relationship between nightmares and the high risk of PTSD when subjects were grouped as a function of the increasing/decreasing frequency. Finally, our findings are partly coherent with the continuity hypothesis between oneiric and waking experiences.

Objective/background: Poor sleep hygiene is considered an exacerbating and perpetuating factor of sleep disturbances and is also associated with poor mental health. The Sleep Hygiene Index (SHI) is a self-report measure assessing adherence to sleep hygiene practices. The aim of this study was to estimate the psychometric properties of the SHI in an Italian representative sample of the general population, following a formative measurement approach. Patients/methods: Participants (n = 6276; M = 33.62, SD = 13.45) completed the SHI alongside measures of sleep disturbance, depression, anxiety, and stress. To consider the item formative nature, sets of item-composites weighted by means of canonical correlation analysis was created and a confirmatory factor analysis (CFA) was implemented. Factorial invariance tests were computed considering both presence of sleep problems and presence of emotional distress symptoms as grouping variables. Results and conclusions: CFA confirmed the unidimensional structure of SHI. Internal consistency was acceptable (ω = 0.752). Test-retest reliability at 8–10 months presented an ICC of 0.666. SHI significantly correlated with sleep, depression, anxiety and stress symptoms (r range from 0.358 to 0.500). Configural and metric invariance were reached for both grouping variables. Partial scalar invariance was obtained only across emotional distress groups. People with emotional symptoms reported higher latent means on the sleep hygiene dimension. Findings support the validity and reliability of the Italian version of the SHI. Importantly, the SHI showed robust psychometric properties both in healthy individuals and in individual reporting mental health symptoms. Thus, it is advisable to use this version of the SHI in both research and clinical practice.
