Lifetime Exposure to Suicide and Current Use of Suicide Prevention Competencies Among Catholic Clergy in Nigeria: A Multidimensional Structural Analysis
Despite the evidence of clergy encounters with both those at risk and survivors of suicide, research examining suicide exposure and the clergy’s use of suicide prevention competencies remains limited. We examined the associations between lifetime exposure to suicide (exposure to suicidal communication, direct exposure to suicide attempts/deaths, and indirect exposure to suicide attempts/deaths) and current use of suicide prevention competencies (…
Clinical and psychosocial correlates of virological severity in paediatric HIV: A retrospective cross-sectional record review in South Africa
This retrospective record review examined psychosocial and clinical correlates of virological severity among children and adolescents aged 0-19 years with detectable viral load in the Ngaka Modiri Molema District, South Africa. Of 124 records screened, 109 were eligible and had a classifiable viral-load outcome. The most robust finding was that reported missed doses were inversely associated with high-level virological failure, whereas ART durati…
The survival penalty: Age-based inequities in hypertension and diabetes management in African health systems (1990–2022) – a secondary quantitative analysis
Africa is experiencing rapid population ageing, yet many health systems remain oriented towards acute and infectious disease care. Whether population-level indicators of hypertension and diabetes management remain comparable across older age groups is unclear. We assessed age-associated differences in chronic disease care cascade indicators across African Union member states using age-stratified estimates from the NCD Risk Factor Collaboration (N…
Career-Related Anxieties and Job Search Outcomes: Testing a Moderated Mediation Model
The study explored whether career mentoring moderates the direct and indirect relationship between career-related anxieties and job search outcomes through job search strategies. Three-wave panel data were collected from three hundred and fifteen (315) unemployed graduates in Southeastern Nigeria. Results from Structural Equation Modelling (SEM) provided support for the direct, indirect, and moderation hypotheses. Specifically, the results showed…
Gray Divorce After 50: A Scoping Review of Antecedents, Consequences, and Family‐Theoretical Gaps
Gray divorce, marital dissolution at Age 50 and older, has become an increasingly important family transition with implications for later‐life kinship, economic security, intergenerational ties, and postmarital adjustment. This scoping review maps antecedents, outcomes, moderators, and family‐theory gaps across 25 empirical studies published between 2012 and 2025 and identified through five major databases, Google Scholar, and targeted citation‐b…
Work-Active Ageing or Healthy Worker Selection? Late-Life Employment and Happiness Among Older Migrants in Europe
Policies promoting work-active ageing assume that extending working lives improves later-life well-being. Among migrants, late-life employment is shaped by migration-related selection and labour-market stratification, which may inflate associations with work well-being. We test whether an apparent work-active immigrant paradox (older migrants appearing both more likely to remain in paid work and more likely to report higher happiness) reflects be…

Perceptions of Ageing and Psychological Well-Being in Older Adults: A Systematic Review and Meta-Analysis
As global populations age, identifying modifiable factors to enhance later-life well-being is vital. Self-perceptions of ageing (SPA), internalised beliefs about one’s ageing, may shape psychological well-being (PWB). We synthesised 33 studies (n = 43,556). Random-effects models showed that more positive SPA related to higher PWB (pooled r = .35; I 2 ≈ 89%). By domain: hedonic r = .24 (95% CI .09–.37); eudaimonic/relational r = .26 (95% CI −.50–.…
Do Perceived Insider Status Influence Intent to Stay Among Nurses: The Mediating Role of Psychological Ownership
Intent to stay is a phenomenon that has remained one of the recipes for an efficient and vibrant organization, which is pivotal to organizational success and continuity in Nigerian organizations. However, more knowledge of the influencing factors and mechanisms must be gained. Based on the theory of planned behavior, this present study, adopting a two-wave design, conducted a cross-sectional survey of 515 nurses of federal government-owned hospit…
Discrimination, trust, and well-being: Dual risk-and-resilience pathways among African immigrants in 29 European countries
Findings suggest discrimination is associated with lower (bridging) trust and poorer well-being. In contrast, social exclusion is associated with a small, trust-mediated (bonding) pathway without a direct SWB benefit. Given the cross-sectional design and absence of race/skin-colour measures in ESS, implications are illustrative: reducing discriminatory experiences and co-designing initiatives that foster intercultural contact (bridging) and commu…
Kin to strain: Longitudinal impacts of family size on mental health among aging South Africans
Objectives This study examines the longitudinal relationship between the number of children and psychological well-being, specifically depressive symptoms and subjective well-being (SWB), among older adults in rural South Africa. Grounded in life course theory and the family stress model, it explores whether larger family sizes offer protection or constitute psychological stressors in later life, with attention to gender differences. Methods Data…
Mental health among high school students in South Africa: Roles of childhood adversity, bullying behaviour, peer pressure, and self-esteem

Paradox of life after work: A systematic review and meta-analysis on retirement anxiety and life satisfaction
Retirement is a pivotal life transition that often changes routines, identity, and objectives. With increasing life expectancies and evolving societal norms, examining the interplay between retirement anxiety and life satisfaction is vital. This study delves into this relationship, recognising the complexities of retirement. A systematic review and meta-analysis followed PRISMA guidelines. Research from 2003 to 2023 was sourced from databases lik…
Beyond the shadows of trauma: Exploring the synergy of emotional intelligence and distress disclosure in Nigerian adolescents’ trauma journey
Although adolescence is a critical period marked by increased vulnerability to trauma, the mechanisms underlying how adolescents cope with such experiences remain underexplored. This study is anchored in Hobfoll’s conservation of resources theory and Porges’ polyvagal theory, which together suggest that emotional intelligence and distress disclosure are critical resources for adolescents coping with trauma and investigated the interplay of distre…

Social support and health-related quality of life in Nigerian cancer patients: Role of cancer-related stress
We investigated the mediating influence of cancer-related stress (CRS) in social support health-related quality of life (HRQoL) among Nigerian cancer patients. Nigerian cancer patients (n = 316; female = 64.6%; mean age = 50.16 years, SD = 13 years) completed measures of perceived social support, CRS, and HRQoL. Structural model data analysis revealed social support was associated with lower HRQoL. CRS (intrusive domain) mediated the association …
Who Cares about Time? Investigating Personality and Self-regulation in the Relationship Between Religiosity and Punctuality in Nigerian Public Service Organizations
The study examined the relationship between religiosity and punctuality, and whether self-regulation mediates this relationship. The study also explored whether personality traits moderate the positive relationship between religiosity and self-regulation and between religiosity and punctuality. Using PROCESS model 4, among 734 federal university employees in the South-east Nigeria, the results of the study showed that religiosity related positive…
Psychological Contract Breach and Turnover Intentions Among Lecturers: The Moderating Role of Organizational Climate
Lecturing in private universities in Nigeria is one of the most challenging jobs for early career scholars. Regrettably, there is a high rate of turnover once an opportunity for exit presents itself. Researchers have proposed a relationship between psychological contract breach and turnover intentions. This study attempted to evaluate the effect of organizational climate in the link between psychological contract breach and turnover intentions us…

The “African Time” Syndrome: Understanding Lateness among Nigerian Public Service Workers
Lateness to meeting or what has been commonly referred to as “African time” is increasingly becoming part of social life in most African countries. Although this phenomenon has crept into the work environment of most Nigerian public service organizations, it has attracted limited research attention. In the study, we explored the definition of lateness to meetings and appointments, and rating of frequency of lateness to meetings among 577 public s…
Cancer coping self-efficacy mediates the relationship between mental adjustment to cancer and health-related quality of life in persons with cancer
Individuals with cancer experience significant levels of distress. Improving health-related quality of life of persons with cancer is a major focus in cancer treatment. This study investigated the mediating role of self-efficacy for coping with cancer in the relationship between mental adjustment to cancer and health-related quality of life among individuals with cancer. Two hundred and fourteen persons with cancer (male = 74, female = 140, mean …
Post-traumatic growth mediates the relationship between valences of trauma centralisation and health-related quality of life
Emotions arising from health-related trauma can be complex (as positive and negative feelings are possible) and can influence the way patients perceive themselves and the world. Health outcomes can also be affected by the valence of emotions. We hypothesised that post-traumatic growth is the mediating link between the valences of event centrality and health-related quality of life among people living with HIV. Three hundred (male = 194 and female…
Psychometric validation of the centrality of events scale in a Nigerian clinical sample
We sought to validate the Centrality of Event Scale (CES) in a Nigerian clinical sample of people living with HIV/ ADS. Our sample consisted of 869 people living with HIV/AIDS. They completed the CES, the Posttraumatic Stress Disorder (PTSD) Checklist for the Diagnostic and Statistical Manual version 5 (DSM-5), and the Posttraumatic Growth Inventory-short form for concurrent validation. Following exploratory factor analysis (EFA) and confirmatory…
Measuring bankers’ deviant behaviour: Structure and reliability in a Nigerian sample
In combating the increasing number of challenges faced by the banking industries that range from disobedience to standard operations, connivance with fraudulent clients, and regular counterproductive behaviours, a measure of deviant behaviour in the banking sector is necessary. We validated a measure of deviant behaviour among Nigerian bankers (n = 492; female = 222 (46%), male = 260 (54%); mean age = 31.72, SD = 6.88 years). Factor analysis yiel…

Evaluating fit of the Prospective and Retrospective Memory Questionnaire (PRMQ) in a Nigerian adult population
This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have…
Parents of children with Down Syndrome: Do resilience and social support matter to their experience of carer stress
The study investigated personal resilience influences on the relationship between social support and parenting-stress among parents of children with Down syndrome (DS) in a Nigerian sample. One hundred and ninety three parent-carers of children with DS participated in the study (mothers = 59%; mean age = 46.47, age range = 21 to 67, SD = 10.42). The parent-carers responded to the measures of parenting-stress, perceived social support, and resilie…
Bringing out the creativity in you: How a competitive climate and mentoring kindle creative work involvement of university academic staff
We investigated mentoring as a moderator between competitive climate and employee creative work involvement. Participants were 270 academic staff of a Nigerian federal university (male = 155 [57.41%] and female = 115 [42.59%]). The participants were employed as Graduate Assistant = 15 (5.56%), Assistant Lecturer = 78 (28.89%), Lecturer II = 61 (22.59%), and Lecturer I = 116 (42.96%). The participants responded to surveys on competitive climate, m…
Pre-retirement anxiety: Development and validation of a measurement instrument in a Nigerian sample
Two studies were conducted to develop and provide evidence supporting the construct validity and internal consistency of scores from the Nigerian Pre-retirement Anxiety Scale (NPAS). The measure comprises three dimensions: financial preparedness, social obligation, and social alienation. In the first study, data collected from 424 civil servants supported the proposed dimensionality of scale scores and internal consistency (Cronbach’s alpha for t…
