This scoping review aimed to explore the nature and structure of Student Counselling and Development Units(SCDUs)in Africa towards a better understanding of the role they play in African Higher Education Institutions(... This scoping review aimed to explore the nature and structure of Student Counselling and Development Units(SCDUs)in Africa towards a better understanding of the role they play in African Higher Education Institutions(HEIs).A comprehensive literature search of ten years(2015-2025)on five electronic databases was conducted.Titles and abstracts were screened,and full articles examined,resulting in 23 studies meeting the inclusion criteria.Using thematic analysis,five main overarching themes were identified:(i)the scope and focus of services in SCDUs,(ii)multidisciplinary teams,(iii)approaches to service provision,(iv)challenges in providing effective support,and(v)adaptability of SCDUs.These themes highlighted that SCDUs offer a multidimensional range of support services and adopt systems-based frameworks.Moreover,they face significant challenges,including limited resources,poor service utilization,and the need for culturally sensitive practices.Conversely,a major strength is their adaptability of implementing online and blended service delivery models. 展开更多

Background:Mental health concerns among doctoral students have become increasingly prominent,with consistently low levels of well-being making this issue a critical focus in higher education research.This study aims to synthesize existing evidence on the mental health and well-being of doctoral students and to identify key factors and intervention strategies reported in the literature.Methods:A systematic review was conducted to examine the determinants and interventions related to doctoral students’mental health and well-being.Relevant studies were comprehensively searched in Web of Science,PubMed,Scopus,and EBSCO,with the final search conducted on September 19,2025.Records were screened according to predefined criteria:empirical studies on doctoral students’mental health or well-being published in English were included,while non-empirical,non-English,and non-doctoral-student-focused studies were excluded.A total of 56 studies were included after rigorous screening.Results:Doctoral students’mental health and well-being are shaped by multiple interacting factors across individual,academic,interpersonal,organizational,and environmental levels.Moreover,variations in gender,identity,discipline,study stage,and institutional context may further exacerbate or mitigate psychological distress.Existing intervention studies primarily focus on three approaches:psychologically oriented training,practice-based behavioral and learning programs,and relationship-or support network-based initiatives.Conclusion:This review offers integrated evidence on doctoral students’mental health and well-being and highlights the need for universities to assume greater responsibility in developing systematic and responsive support mechanisms.Current research remains limited by insufficient cross-cultural comparison,a lack of intersectional perspectives,and a scarcity of large-scale,long-term evaluations of intervention effectiveness.Future studies should give greater attention to institutional contexts and vulnerable groups while expanding the scope and rigor of intervention research. 展开更多

Nursing education in Indonesia experienced a number of changes during the new normal.The biopsychosocial health status reveals how students can complete their studies well at nursing school in the new normal.A quantitative,descriptive correlational study sampled 368 student nurses from2 universities.This study used a biopsychosocial questionnaire,which included biological,physiological,and social dimensions.In this study,there was no significant demographic student nurse relationship with the biological,psychological,and social dimensions of health,at P-value 0.05(Age P=0.70,P=0.27,P=0.93)sex(P=1,P=0.919,P=0.5),as well as grade level(P=0.9,P=0.37,P=0.64).Student nurses were dynamic,such as process input,resulting in coping adaptation and the ability to care for themselves.There was a relationship between both universities with a psychological dimension and a P-value of 0.049.In terms of Generation Z technology,both universities played a role.Lifestyle influences can lead to intense feelings of isolation and loneliness in some teens,including self-negativity,fear of missing out on information,and shame about not meeting appropriate standards for social media.The influence of an unhealthy lifestyle impacts stress and anxiety.The student nurses assigned considered themselves to be“healthy”in terms of their biopsychosocial health status.Student nurses continued to develop in their biopsychosocial health by utilizing different coping strategies to adapt and adjust to their environment in their school of nursing. 展开更多

Objectives:Psychological resilience is a critical resource for vocational high school students navigating social biases and fostering mental well-being.This six-month longitudinal study investigated the developmental trajectories of discrimination perception,vocational identity,and psychological resilience in this population.It further examined the longitudinal mediating role of vocational identity in the relationship between discrimination perception and psychological resilience.Methods:A total of 526 students from five vocational high schools in Guangdong,China,were assessed via convenience sampling at two time points:baseline(T1,September 2023)and six-month follow-up(T2,March 2024).Measures of discrimination perception,psychological resilience,and vocational identity were administered.Data were analyzed using a cross-lagged panel model to test for bidirectional relationships.Results:Over the six-month period,students showed significant decreases in discrimination perception and vocational identity,but a significant increase in psychological resilience.The cross-lagged model revealed significant bidirectional relationships:discrimination perception and psychological resilience negatively predicted each other over time(β=−0.124,p<0.01;β=−0.200,p<0.001),while psychological resilience and vocational identity positively predicted each other(β=0.084,p<0.05;β=0.076,p<0.05).The mediation analysis revealed a dual-pathway mechanism.T1 discrimination perception exerted both a significant direct negative effect on T2 psychological resilience(β=−0.332,p<0.001)and a significant indirect positive effect via T1 vocational identity(indirect effect=0.020,95%CI[0.001,0.046]).This confirms a partial mediating role,indicating that vocational identity functions as a compensatory mechanism,transforming the experience of discrimination perception into a potential source of psychological resilience.Conclusions:For vocational high school students,perception of discrimination directly undermines psychological resilience,but also indirectly fosters it through the positive development of vocational identity.These findings highlight vocational identity as a pivotal mechanism in the complex relationship between social adversity and mental resilience. 展开更多

BACKGROUND Revisiting the epidemiology of posttraumatic stress symptoms(PTSSs)among university students during the coronavirus disease 2019(COVID-19)pandemic as well as understanding the mental health help-seeking behavior of individuals with PTSSs has critical implications for public mental health strategies in future medical pandemics.AIM To investigate the prevalence and correlates of PTSSs among university students during the first wave of the COVID-19 pandemic in China and to examine mental health help-seeking behaviors among these students.METHODS A total of 2507 Chinese university students were recruited via snowball sampling.The students completed the Seven-item Screening Scale for Post-traumatic Stress Disorder during the first wave of the COVID-19 pandemic in China.Sociodemo-graphic characteristics,pandemic-related characteristics,and mental health help-seeking behaviors of students with PTSSs were also collected.RESULTS The prevalence of PTSSs among the participants was 28.0%.Seven significant correlates of PTSSs were identified(odds ratio=1.23-3.65,P≤0.024):Female sex,being 19 years old or older,living with others or alone,a low level of family economic status,fair or poor interpersonal relationships,severe or very severe local pandemic,and having family members diagnosed with COVID-19.However,only 3.28%of the students with PTSSs reported seeking help from mental health specialists.Among the 23 students who sought help from mental health specialists,13 opted for online or telephone-based psychological consultation.CONCLUSION Our data suggest that there was a high risk of PTSSs among university students and a high level of unmet mental health needs during the COVID-19 pandemic.The delivery of mental health services online or via telephone is a promising approach to address these unmet needs. 展开更多
