Background and aims: Mobile phone addiction (MPA) is frequently reported to be correlated with anxiety, depression, stress, impulsivity, and sleep quality among college students. However, to date, there is no consensus on the extent to which those factors are correlated with MPA among college students. We thus performed a meta-analysis to quantitatively synthesize the previous findings.Methods: A systematic review and meta-analysis was conducted by searching PubMed, Embase, Cochrane Library, Wanfang, Chinese National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Chinese Biological Medicine (CBM) databases from inception to August 1, 2020. Pooled Pearson's correlation coefficients between MPA and anxiety, depression, impulsivity, and sleep quality were calculated by R software using random effects model.Results: Forty studies involving a total of 33, 650 college students were identified. Weak-to-moderate positive correlations were found between MPA and anxiety, depression, impulsivity and sleep quality (anxiety: summary r = 0.39, 95% CI = 0.34–0.45, P < 0.001, I² = 84.9%; depression: summary r = 0.36, 95% CI = 0.32–0.40, P < 0.001, I² = 84.2%; impulsivity: summary r = 0.38, 95% CI = 0.28–0.47, P < 0.001, I² = 94.7%; sleep quality: summary r = 0.28, 95% CI = 0.22–0.33, P < 0.001, I² = 85.6%). The pooled correlations revealed some discrepancies when stratified by some moderators. The robustness of our findings was further confirmed by sensitivity analyses.Conclusions: The current meta-analysis provided solid evidence that MPA was positively correlated with anxiety, depression, impulsivity, and sleep quality. This indicated that college students with MPA were more likely to develop high levels of anxiety, depression, and impulsivity and suffer from poor sleep quality. More studies, especially large prospective studies, are warranted to verify our findings.

This study aimed to explore the associations of occupational stressors (extrinsic effort, reward, and overcommitment), perceived organizational support (POS), and psychological capital (PsyCap) and its components (self-efficacy, hope, resilience, and optimism) with work engagement and the mediating roles of PsyCap and its components among Chinese female nurses within the framework of the job demands-resources (JD-R) model. A cross-sectional sample (1,330) completed the Utrecht Work Engagement Scale, Effort-Reward Imbalance Scale, Survey of POS, and PsyCap Questionnaire, and effective respondents were 1,016 (76.4%). Hierarchical regression analysis and Preacher and Hayes’ asymptotic and resampling strategies were used. Extrinsic effort was negatively associated with vigor, dedication, and absorption, while POS, PsyCap, and hope were positively associated with them. Reward and overcommitment were positively associated with dedication and absorption. Optimism was positively associated with vigor and dedication. Optimism mediated the associations of extrinsic effort, reward, and POS with vigor and dedication. PsyCap and hope mediated the associations of POS with vigor, dedication, and absorption. There is a low level of work engagement among Chinese female nurses. Extrinsic effort could reduce work engagement, while reward, overcommitment, POS, PsyCap, hope, and optimism could enhance work engagement. Hospital managers should develop the PsyCap of female nurses through controlling occupational stressors and establishing supportive organizational climate to enhance their work engagement.

Purpose: Nurses are undertaking considerable emotional and physical work, which may lead to unrecoverable fatigue. This study aimed to evaluate the level of chronic fatigue and explore its associated factors among Chinese nurses in the hope of providing scientific evidence for fatigue-reduction strategies. Methods: This cross-sectional study was carried out in Liaoning Province, China in 2018. The study recruited 700 nurses and collected 566 effective respondents. Chronic fatigue, demographic factors, job conditions, and emotional intelligence were assessed through questionnaires. Chronic fatigue was assessed with the Fatigue Scale 11, occupational stress with the Effort–Reward Imbalance Questionnaire, and emotional intelligence with the Wong and Law Emotional Intelligence Scale. Hierarchical multiple regression was used to explore factors related to chronic fatigue and to test the moderating effect of emotional intelligence on the association between occupational stress and chronic fatigue. Simple slope analysis was conducted to visualize the interaction. Results: The mean score of chronic fatigue among the Chinese nurses was 17.14±6.16. Being married, having long weekly work time, working night shifts, and discontent with the nurse–patient relationship were positively associated with chronic fatigue. Effort:reward ratio, overcommitment, and emotional intelligence were important factors related to chronic fatigue. Emotional intelligence played a moderating role in the relationship between the effort:reward ratio and chronic fatigue. When emotional intelligence was higher, the effect of the effort:reward ratio on chronic fatigue became weaker. Conclusion: Most nurses surveyed in China might have relatively high levels of chronic fatigue. Our results highlight the importance of interventions on these factors for the reduction of fatigue among nurses in China. Providing more opportunities and support and developing emotional intelligence are crucial strategies to reduce chronic fatigue among nurses in China.

Background: Pregnancy can be stressful for women and families, so the life satisfaction of pregnant women may face significant challenges. This study aimed to identify the relationship among anxiety symptoms, perceived social support and life satisfaction, and to further explore whether perceived social support can play a mediating role. Methods: This cross-sectional study was conducted from June to September in Shenyang City, China in 2019. 290 effective questionnaires were collected. The Satisfaction with Life Scale (SWLS), the Zung’s Self-Rating Anxiety Scale (SAS), the Multi-Dimensional Scale of Perceived Social Support (MSPSS) as well as demographic variables were included in each questionnaire. Hierarchical multiple regression was conducted to explore the mediating role of perceived social support in the relationship between anxiety symptoms and life satisfaction. Then the mediation model was examined by the PROCESS macro for SPSS. Results: After adjusting control variables, anxiety symptoms were negatively associated with life satisfaction and explained 14.7% of the variance. Higher level of perceived social support was related to higher level of life satisfaction, explaining 21.0% of the variance. Perceived social support partly mediated the relationship between anxiety symptoms and life satisfaction for pregnant women. Conclusions: Perceived social support played a mediating role between anxiety symptoms and life satisfaction among pregnant women. Strategies and measures to improve perceived social support may be expected to buffer the impact of anxiety symptoms on pregnant women’s life satisfaction.

Background: The COVID-19 pandemic has caused a mental health crisis around the world. The psychological health of college students also faces great challenges. This study aimed to investigate the prevalence and the related factors of depressive symptoms among Chinese college students. Methods: This online cross-sectional survey was conducted via Wenjuanxing platform from March 3–15, 2020 and received 1681 effective questionnaires. Each questionnaire contains the Center for Epidemiologic Studies Depression scale, the Multi-Dimensional Scale of Perceived Social Support, the Herth Hope Index, and the self-designed items. Multivariable logistic regression was conducted to determine the significantly associated factors of depressive symptoms. Results: The prevalence of depressive symptoms among college students was 56.8%. Sleep problems (OR 2.678, 95%CI 2.094–3.424), family members’ going out (OR 1.775, 95%CI 1.089–2.894), perceived more stress for online education (OR 1.642, 95%CI 1.191–2.263), fear of COVID-19 (OR 1.450, 95%CI 1.121–1.876), influence on social interaction (OR 1.354, 95%CI 1.053–1.741) and higher grade (OR 1.378, 95%CI 1.046–1.816) were considered as risk factors of depressive symptoms. Perceived social support (OR 0.354, 95%CI 0.259–0.484), hope (OR 0.052, 95%CI 0.034–0.080), female (OR:0.557, 95%CI 0.427–0.725) and higher monthly disposable income (OR 0.666, 95%CI 0.447–0.993) were identified as protective factors against depressive symptoms. Conclusions: There was a high prevalence of depressive symptoms among Chinese college students during the COVID-19 pandemic. It is important to find ways to alleviate the pressure and fear of college students, to provide them with more social support, and to help them adapt to the changes in learning style and lifestyle.

Background: Women with breast cancer are prone to have mental stress and be stimulated by the fear of progression (FOP), then giving rise to a lower quality of life (QOL). The study aimed to examine the relationships between FOP, social support and QOL, and further explore whether social support mediates the association between FOP and QOL among Chinese patients with breast cancer.Methods: The cross-sectional study was conducted from October 2019 to May 2020 at Anshan Cancer Hospital in Liaoning, China. 244 female breast cancer patients completed questionnaires including the Functional Assessment of Cancer Therapy for Breast (FACT-B), Multi-Dimensional Scale of Perceived Social Support (MSPSS), and Fear of Progression (FOP). Hierarchical multiple regression analysis was performed to assess the associations between FOP, social support and QOL. Asymptotic and resampling strategies were used to explore the mediating role of social support.Results: The mean QOL score was 90.6 ± 17.0 among the patients with breast cancer. FOP was negatively correlated with QOL, while social support was positively related to QOL. Social support partly mediated the association between FOP and QOL, and the proportion of the mediating effect accounted for by social support was 25%.Conclusions: Chinese breast cancer patients expressed low QOL. Social support could mediate the association between FOP and QOL. Medical staffs and cancer caregivers should alleviate patients’ FOP to improve their QOL by facilitating social support.
