The psychological condition of community-dwelling older adults is a global concern under coronavirus disease 2019. Loneliness is the key risk factor for depression among community-dwelling older adults. This study aims to explore the role of social support as a mediating factor in the relationship between depression and loneliness among community-dwelling older adults. We conducted a cross-sectional study in Chenzhou, Hunan Province, China, from June to December 2021. The sample consisted of 570 community-dwelling adults aged over 60 years. Data were collected through a general information questionnaire, the Social Support Rating Scale, the University of California at Los Angeles Loneliness Scale, and the Center for Epidemiological Survey, Depression Scale. Statistical Package for the Social Sciences PROCESS macro was used to examine the mediating effect of social support between loneliness and depression. This study found that depression was negatively associated with social support (r = −0.381, P < .001), but it was positively correlated with loneliness (r = 0.403, P < .001); loneliness was a predictor of depression (B = 0.333, P < .001). In addition, social support significantly mediated the relationship between loneliness and depression, with an indirect effect of 0.239 (95% Bootstrap CI −0.264 to −0.510), the overall effect value for depression was 0.572, accounting for 56.3% of the total variance in depression within this model. In conclusion, the findings suggest that social support plays a mediating role between depression and loneliness in older adults. This implies that interventions aimed at reducing loneliness and enhancing social support have the potential to alleviate depressive symptoms among this population. By addressing these factors, healthcare professionals and caregivers can promote the mental well-being of older adults and contribute to improved overall quality of life.

Purpose: The cases of workplace violence (WPV) experienced by nurses and nursing students in recent years has become alarming high. However, managing and developing WPV competence among nursing students remain underreported. Therefore, this study investigated the current status of management of workplace violence competence (MWVC) and identify associated factors affecting their MWVC among nursing interns. Participants and Methods: A total of 817 nursing interns from six tertiary hospitals in Hunan Province, China, participated in this study in July 2023. Data were collected via online survey questionnaires using the Management of Workplace Violence Competence Scale (MWVCS), the Patient Risk Identification Ability Assessment Questionnaire, and the Professional Identity Questionnaire for Nursing Students (PIQNS). Results: Among participants, 91.1% were female (n=744), 68.1% (n=556) were between 21 to 23 years old, and 54.1% (n=442) obtained a bachelor’s degree. The score of management of workplace violence competence was 123.25 (SD=11.06). The multiple linear regression analysis showed that the diploma degree (B=3.152, p< 0.001, 95% CI: 2.087– 4.217), witnessed a workplace violence incident in a hospital (B=4.274, p< 0.001, 95% CI: 3.164– 5.384), trained in WPV prevention skills (B=7.196, p< 0.001, 95% CI: 6.007– 8.386), patient risk identification ability (B=1.006, p< 0.001, 95% CI: 1.163– 0.893), and professional identity (B=0.693, p< 0.001, 95% CI: 0.571– 0.815) were the associated factors of MWVC among nursing interns. Conclusion: The MWVC among nursing interns was at an intermediate level. To enhance MWVC, it is recommended to strengthen WPV prevention and management training, particularly for interns with diploma degrees, no experience witnessing WPV incidents, no prior training in WPV prevention skill, and lower levels of patient risk identification ability and professional identity. Our findings may guide the establishment of focused training programs and support measures to improve interns’ capacity to manage WPV, increasing their professional growth and mental health while giving significant insights and intervention techniques for nursing educators and managers.
