Depression and mania symptoms mediate the relationship between insomnia and psychotic-like experiences in the general population

Psychotic-like experiences (PLEs) are subclinical forms of psychosis commonly experienced in the general population. The nature of PLEs has yet to be clearly defined, yet mood and sleep disturbances may be two predictors. Sleep disturbance increases paranoia and hallucinations in experimental studies, and insomnia is considered a longitudinal precursor of psychosis. Mood disturbances including depression and mania, which can be induced by insomnia, can also result in psychotic symptoms. However, whether insomnia may predict PLEs via the mediation of mood disturbance has yet to be fully clarified. To advance this field, the aim of this study was to investigate the mediation role of depression and mania symptoms on the relationship between insomnia and PLEs. 1.086 community members (28.32±9.04 years, 58.1% females) cross-sectionally completed self-reported measures of insomnia severity, depression/mania symptoms, and PLEs. Bivariate correlations, hierarchical multiple regressions and mediation analyses with bootstrap approach were performed. Insomnia and mood disturbances (depression/mania) were significantly associated with PLEs (β = 0.06, p < .05; β = 0.225, p < .001, respectively). Mediation analysis revealed a significant indirect effect between insomnia and PLEs mediated by mood disturbance through bootstrap approach (β=0.13, se= 0.02, 95% CI: 0.10 - 0.17). Our results support the view of insomnia and mood disturbances as predictors of PLEs in the general population and foster the replication of these findings using longitudinal designs

Time waits for no one: longitudinal study on the effects of an anti-stigma seminar on the psychology student population

The primary aim is to describe the changes in the knowledge of mental health conditions, the attitudes toward the mentally ill, and the intended behaviour towards people with mental illness among the entire student population of the third year of a degree course in Psychology. A total of 570 students attended a seminar on stigma towards mental illness and were invited to complete an online survey which collected data on sociodemographic characteristics and three validated questionnaires evaluating different aspects of stigma at three different time points (pre-intervention, post-intervention, and at one year follow up). A total of 253 students (44.39%) completed the questionnaires at t0, t1, and t2. The mean age of the sample was 23.7 (SD = ±5.89), and 86.96% (n = 220) were females. Between t0 and t1, a statistically significant improvement was observed for all three outcomes, while the intended behaviour outcome was no longer significant between t1 and t2 (Z = −0.70; p = 0.48). Females and who participated live at the seminar maintained a significant knowledge of mental illness and a better attitude toward community mental health care. The effects of the seminar focused on reducing stigma tended to diminish over time at one year follow-up, particular in relation to intended behaviour

Dreams and Nightmares during the First and Second Wave of the COVID-19 Infection: A Longitudinal Study

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

Problematic social networking sites use and attachment: A systematic review

A systematic review of the literature was conducted to summarize research that examined the associations between problematic social networking sites use (PSNSU) and attachment-related phenomena among adolescents and adults. Records were included in the systematic review if they presented original data, assessed attachment and PSNSU, were published in peer-reviewed journals between 2004 and 2021 and were written in English. After duplicates removal, 373 studies were found eligible for scrutiny. Among the screened full texts, 32 articles met the eligibility criteria. The selected studies included a total of 16,938 participants. Findings from these studies highlighted that PSNSU is negatively associated with indicators of secure attachment and positively associated with indicators of attachment anxiety, whereas results regarding indicators of attachment avoidance were mixed. Furthermore, an analysis of mediators showed that the relationship between PSNU and attachment-related phenomena is affected by individual, interpersonal, and SNS-related variables. Future directions for research as well as implications for clinical practice are discussed

Exposure to animal suffering, adult attachment styles, and professional quality of life in a sample of Italian veterinarians.

Contextual and individual risk factors of veterinarians' professional quality of life are being debated. Research suggests that attachment styles are relevant predictors of professional quality of life; however, their role in work-related well-being of veterinarians is yet to be ascertained. In the present study, self-report measures on exposure to animal suffering, adult attachment styles, and professional quality of life were administered to 1,445 Italian veterinarians (70% females) aged 24 to 74 years old; sociodemographic information and information on workload were also collected. Female gender, higher levels of ordinary workload, on-call hours per week, exposure to animal suffering, together with fearful and preoccupied attachment styles were significantly associated with lower levels of veterinarians' quality of life. This suggests that work-related factors may combine with individual psychological features in promoting or disadvantaging the professional quality of life of veterinarians. Implications of these findings for promoting veterinarians' quality of life and directions for future research are discussed

Problematic social networking sites use and online social anxiety: The role of attachment, emotion dysregulation and motives

Problematic Social Networking Sites Use (PSNSU) and social anxiety are associated. SNSs users may develop online social anxiety that may become a standalone problem. The present study aims to test the mediating role of emotion dysregulation and motives (coping, conformity, social, and enhancement) between attachment (anxiety and avoidance) and two outcomes (PSNSU and online social anxiety) in an integrated theory-driven model. Self- report questionnaires were completed by 756 SNSs users (50.4 % females; mean age = 28.74 years, SD = 8.00). Results of the path analysis supported the partial mediating role of emotion dysregulation in the association between attachment anxiety and both the outcomes and the serial mediating role via four and three motives in the association with PSNSU and online social anxiety, respectively. This study highlighted the role of several relational, emotional, and motivational factors that should be taken into account to tackle PSNSU and online social anxiety through clinical and prevention interventions
