The COVID-19 pandemic created significant strain on both mental health and romantic relationships. Therefore, we examined longitudinal associations between romantic relationship quality, relationship loneliness, and depressive symptoms over 6 months of the COVID-19 pandemic. We surveyed 122 couples (n = 244 individuals) in approximately May, September, and November 2020. Using a dyadic mediation model, findings indicated that relationship quality at Time 1 was positively associated with depression at Time 3 for men, but not for women. A significant indirect effect of relationship quality on depression via relationship loneliness at Time 2 was found for both men and women. Self-mastery, or feeling in control of one's life circumstances, was an important covariate of women's depressive symptoms. Overall, these findings highlight relationship loneliness as particularly salient for mental health and demonstrate the importance of high-quality relationships for promoting well-being during stressful events, such as global pandemics. 相似文献

Sleep as a mediator of the relationship between social class and health in higher education students
Romany McGuffog Mark Rubin Mark Boyes Marie L. Caltabiano James Collison Geoff P. Lovell Orla Muldoon Stefania Paolini 《British journal of psychology (London, England : 1953)》2023,114(3):710-730
A substantial body of research indicates that higher education students from lower social class backgrounds tend to have poorer health than those from higher social class backgrounds. To investigate sleep as a potential mediator of this relationship, online survey responses of students from five large Australian universities, one Irish university and one large Australian technical college were analysed in three studies (Study 1 N = 628; Study 2 N = 376; Study 3 N = 446). The results revealed that sleep quality, sleep duration, sleep disturbances, pre-sleep worries and sleep schedule variability mediated the relationship between social class and physical and mental health. Sleep remained a significant mediator when controlling for related variables and other mediators. Thus, the findings suggest that sleep partly explains social class differences in health. We discuss the importance of addressing sleep issues among students from lower social class backgrounds. 相似文献

The COVID-19 pandemic has prompted extensive disruptions to the daily lives of children and adolescents worldwide, which has been associated with an increase in anxiety and depressive symptoms in youth. However, due to public health measures, in-person psychosocial care was initially reduced, causing barriers to mental health care access. This study investigated the feasibility, acceptability and preliminary effectiveness of iCOPE with COVID-19, a brief telemental health intervention for children and adolescents to address anxiety symptoms. Sessions were provided exclusively using videoconferencing technology. Feasibility and acceptability were measured with client satisfaction data. The main outcome measure for effectiveness was anxiety symptom severity measured using the Screen for Child Anxiety and Related Disorders (SCARED). Results indicated that the treatment was well accepted by participants. Significant reductions in anxiety were noted for social anxiety, and were observed to be trending towards a mean decrease for total anxiety. The findings suggest that this brief telemental health intervention focused on reducing anxiety related to COVID-19 is acceptable and feasible to children and adolescents. Future research using a large sample and with a longer follow-up period could inform whether symptom decreases are sustained over time. 相似文献

The purpose of this study was to examine the association between esport participation and loneliness, as well as its moderating factors. Chinese college students (N = 216) self-reported their esport playing time and degree of loneliness each day immediately before bedtime for four consecutive weeks. The findings revealed that as playing time increased, students did not experience reduced sense of loneliness during playing esport, but they experienced a temporary and intensified feeling of loneliness the same day following gameplay. Students with higher general loneliness tended to feel more after-game loneliness associated with increased esport participation. Students with higher obsessive passion about esport tended to experience more loneliness (both in-game and after-game) associated with increased esport participation. Students with greater coping motivation about esport tended to experience more in-game loneliness associated with previous increased esport participation. Students who played esport less often with friends in person, or with more escape motivation toward esport, tended to increase esport participation time more following previous increased after-game loneliness. The findings suggested that college students should avoid utilizing esport to achieve a sense of belonging and should be cautious of the loneliness-inducing effect after gameplay. A healthy level of loneliness can be maintained by playing esport more with friends in person, learning strategies to avoid obsessive passion, coping motivation, and escape motivation towards esport. 相似文献

Aims: This study (1) profiled the well‐being of first year students entering one UK university, and (2) explored whether initial well‐being and year end academic performance were correlated. Method: A total of 117 students (mean age 21, 67% female) completed the Rosenberg Self‐Esteem Scale, Clinical Outcomes in Routine Evaluation‐General Population, and Liebowitz Social Anxiety Scale; academic achievement data were collected from academic records. Results: Almost a quarter of the sample reported quasi‐clinical levels of psychological distress and moderate to very severe social anxiety. Quasi‐clinical levels of psychological distress were associated with low self‐esteem and social anxiety. No statistically significant links were found between well‐being as assessed at the beginning of the first year and academic achievement at the end of the first year. Discussion: The failure to find a link in this study between initial well‐being and academic performance at the end of the first year suggests that further investigation is required to understand how academic achievement is related to student well‐being. 相似文献
