Past research suggests that being comparatively optimistic about one's risk for disease is associated with benefits to mental health, such as lowered stress and anxiety. However, few studies have longitudinally examined whether comparative optimism has the same protective benefits during the COVID-19 pandemic. The current study examined levels of comparative optimism, changes in comparative optimism over time, and the association between comparative optimism and COVID-related mental and physical health outcomes among a US adult sample during the COVID-19 pandemic. Participants completed online surveys at four timepoints, over the course of four weeks in May and June of 2020. Results from paired-samples t-tests revealed that comparative optimism was present, such that participants estimated their risk for COVID-19 as being significantly lower than that of others their age and sex. Results from linear mixed models suggested that people who were more comparatively optimistic reported lower anxiety, depression, and stress. However, at times when people were more comparatively optimistic, they also reported greater depression and poorer sleep quality. Together, the findings suggest that the relationship between comparative optimism and health may be more complex than previously anticipated and further research is needed to examine the potential pathways through which comparative optimism affects health. 相似文献
Perfectionism is related to insomnia and objective markers of disturbed sleep. This study examined whether multidimensional perfectionism is related to dysfunctional beliefs about sleep, sleep-effort, pre-sleep arousal, and polysomnography-determined markers of sleep among individuals with insomnia. The effects of cognitive behavioral therapy for insomnia (CBT-I) on perfectionism was also examined. This was a secondary analysis of a randomized controlled trial on CBT-I. Forty-three insomnia patients were randomized to treatment (receiving CBT-I) or waitlist control groups. Sleep was recorded using polysomnography at baseline. Participants completed measures of perfectionism, dysfunctional beliefs about sleep, sleep-effort and pre-sleep arousal at baseline and posttreatment. Total perfectionism scores and doubts about action, concern over mistakes and personal standards were each significantly related to increased sleep effort, pre-sleep arousal and dysfunctional beliefs about sleep at baseline. Patients receiving treatment displayed increased total perfectionism scores posttreatment d = .49. In those receiving treatment, levels of organization d = .49 and parental expectations d = .47 were significantly increased posttreatment, relative to baseline. In line with the literature, our results confirm that perfectionism is related to insomnia. Here, insomnia was related to increased sleep effort, pre-sleep arousal and dysfunctional beliefs about sleep. The propensity to maintain a high standard of order and organization may be elevated following CBT-I, considering the treatment protocol expects patients to strictly adhere to a set of clearly defined rules. Levels of parental expectations may be increased following CBT-I since the patient-therapist-relationship may trigger implicit expectations in patients which are reminiscent of their relationship to their parents. 相似文献
Prior work implicates sleep disturbance in the development and maintenance of posttraumatic stress disorder (PTSD). However, the majority of this literature has focused on combat veteran men, and limited work has examined links between sleep disturbance and PTSD symptoms in sexual assault survivors. This is a notable gap in the literature, as sexual trauma is disproportionately likely to result in PTSD and is more common in women. We sought to examine the relations between subjective sleep disturbance, sexual assault severity, and PTSD symptoms in a sample of sexual assault survivors with PTSD (PTSD+), without PTSD (PTSD-), and healthy controls. The sample (N = 60) completed the Insomnia Severity Index and prospectively monitored their sleep for 1 week using the Consensus Sleep Diary. The sexual assault survivors also completed the Sexual Experiences Survey and PTSD Checklist-5. Results of group comparisons found that the PTSD+ group reported significantly higher insomnia symptoms, longer sleep onset latency, more nocturnal awakenings, and lower sleep quality compared to the healthy control group and higher insomnia symptoms compared to the PTSD- group. Results of regression analyses in the sexual assault survivors found that insomnia symptoms and number of nocturnal awakenings were significantly associated with higher PTSD symptoms, and sexual assault severity was significantly associated with higher insomnia symptoms, longer sleep onset latency, and lower sleep quality. These findings highlight specific features of sleep disturbance that are linked to trauma and PTSD symptom severity among sexual assault survivors. 相似文献
Social and emotional loneliness negatively impact several areas of health, including sleep. However, few comprehensive population‐based studies have evaluated this relationship. Over 12,000 students aged 21–35 years who participated in the student survey for higher education in Norway (the SHoT study) were assessed. Loneliness was assessed using the Social and Emotional Loneliness Scale. Difficulty initiating and maintaining sleep (DIMS) was assessed by a single‐item subjective response on the depression scale of the Hopkins Symptoms Checklist (HSCL‐25). Social loneliness was associated with more serious DIMS (unadjusted proportional odds‐ratio [OR] = 2.69, 95% CI = 2.46–2.95). This association was attenuated following adjustment for anxiety (adjusted OR = 1.92, 95% CI = 1.75–2.10) and depression (adjusted OR = 1.48, 95% CI = 1.34–1.63), however was not substantially altered when all demographics and psychological distress were accounted for (fully adjusted OR = 1.46, 95% CI = 1.30–1.63). Emotional loneliness was also associated with more serious DIMS (unadjusted proportional OR = 2.33, 95% CI = 2.12–2.57). Adjustment for anxiety (adjusted OR = 1.96, 95% CI = 1.78–2.15) and depression (adjusted OR = 1.64, 95% CI = 1.48–1.80) attenuated, but did not extinguish this relationship in the fully adjusted model (adjusted OR = 1.22, 95% CI = 1.09–1.31). Mediation analyses revealed that the social loneliness‐DIMS association was fully attributed to psychological distress, while the emotional loneliness‐DIMS association was only partially mediated, and a direct association was still observed. Associations between social and emotional loneliness and subjective DIMS were embedded in a larger pattern of psychological distress. Mitigating underlying feelings of loneliness may reduce potentially deleterious effects on sleep health and psychological wellbeing in young adults. 相似文献
Disordered sleep is strongly linked to future depression, but the reasons for this link are not well understood. This study tested one possibility – that poorer sleep impairs emotion regulation (ER), which over time leads to increased depressive symptoms. Our sample contained individuals with a wide range of depression symptoms (current depression, N?=?54, remitted depression, N?=?36, and healthy control, N?=?53), who were followed clinically over six months and reassessed for changes in depressive symptom levels. As predicted, maladaptive ER mediated both cross-sectional and prospective relationships between poor sleep quality and depression symptoms. In contrast, an alternative mediator, physical activity levels, did not mediate the link between sleep quality and depression symptoms. Maladaptive ER may help explain why sleep difficulties contribute to depression symptoms; implications for interventions are discussed. 相似文献
Objective: Established risk factors for jet lag are mostly physiological including circadian preference, age, gender, the number of flight zones crossed and to some extent direction of travel. Some research has also highlighted a role for psychosocial factors including sleep, diet and ‘circadian’ health behaviours and illness cognitions although this remains relatively untested. The aim of this study was to evaluate the role of sleep, diet and illness cognitions in predicting perceived jet lag amongst long-haul crew.
Design: Sixty long-haul crew took part in a longitudinal study. Profile characteristics (including chronotype), preparation strategies (sleep, eating and ‘circadian’ behaviours) and illness cognitions were measured at baseline (before a trip).
Main outcome measures: Subjective jet lag (unidimensional and multidimensional) was measured on the crews’ second day off (post-trip).
Results: Hierarchical regression analyses showed that unidimensional jet lag was predicted by the belief in a cyclical timeline, whereas multidimensional jet lag was predicted by multidimensional jet lag at baseline and to a lesser extent by identity. No role was found for profile characteristics and preparation strategies.
Conclusion: Illness cognitions partly explain the experience of perceived jet lag in long-haul cabin crew indicating that jet lag is in part a psycho-social construct, not just a biological one. 相似文献
