The demanding nature of the construction industry poses strain that affects the health of construction personnel. Research shows that mental ill health in this industry is increasing. However, a review mapping the field to determine the extant of research is lacking. Thus, the purpose of this paper is to conduct a scientometric review of mental health (MH) research in the construction industry.

A total of 145 bibliographic records retrieved from Web of Science and Scopus database were analyzed using CiteSpace, to visualize MH research outputs in the industry.

Top co-cited authors are Helen Lingard, Mei-yung Leung, Paul Bowen, Julitta S. Boschman, Peter E.D. Love, Martin Loosemore and Linda Goldenhar. Previous studies focused on healthy eating, work efficiency, occupational stress and workplace injury. Emerging research areas are centered around physiological health monitoring, work ability, and smart interventions to prevent and manage poor MH.

Result is influenced by the citations in retrieved articles.

The study found that researchers in the construction industry have intensified efforts to leverage information technology in improving the health, well-being, and safety of construction personnel. Future research should focus on developing workplace interventions that incorporate organizational justice and flexible work systems. There is also a need to develop psychological self-reporting scales specific to the industry.

This study enhances the understanding of researchers on existing collaboration networks and future research directions. It provides information on foundational documents and authors whose works should be consulted when researching into this field.

The need to improve the mental health of construction personnel has increased owing to high rates of mental health problems. Hence, a proper evaluation of a mix of implementable intervention strategies in the workplace will assist in achieving good mental health. Although there are recommendations in occupational health literature on strategies that can be adopted, it is unknown how they fit appropriately into the construction industry. Therefore, the purpose of this study is to identify the mix of strategies for the construction industry and their criticality.

Drawing from the context of developing countries with Nigeria as a case study, data was collected using the quantitative technique. A questionnaire survey consisting of 31 intervention strategies was administered to a purposive sample of 45 experts in the Nigerian construction industry. The data collected was analyzed using mean score analysis and fuzzy synthetic evaluation.

The study revealed that strategies focused on boosting employee morale and engagement and interpersonal relationship offer higher chances of improving mental health among construction personnel. The study showed that implementing job crafting and sculpting may benefit the industry. The analysis showed that the overall criticality of the intervention strategies to the Nigerian construction workplace is high, suggesting that if implemented, the mental health of construction personnel can be improved.

The study provides an initial understanding of the most critical multi-level intervention strategies to enhance good mental health among construction personnel in Nigeria and the global construction industry. These findings serve as a guide to policymakers and advocate the implementation of strategies to adopt for a psychologically healthy construction workplace in developing countries.

International construction joint ventures (ICJVs) are an effective strategy for construction companies worldwide for delivering large and complex projects. Despite numerous ICJVs studies, there is a lack of comprehensive empirical examination of what drives ICJVs implementation. This study aims to investigate the key drivers for implementing ICJVs through an international survey.

Grounded on a comprehensive literature review and structured questionnaire survey, 123 ICJV experts' responses from 24 different countries/jurisdictions were analyzed using inferential and descriptive statistics. Mann–Whitney U test was used to determine any divergence of ranking of the drivers by the experts. Factor analysis (FA) was used to identify the clusters underlying the key drivers. Rank agreement analysis was later used to investigate the consensus between experts from developing and developed countries/jurisdictions on their ranking of the clusters.

Out of 34 factors, 26 factors greatly drive the implementation of ICJVs. Mann–Whitney U test results prove the absence of significant disparity among the experts in the ranking of the drivers. Six clusters were obtained through factor analysis (FA), namely, market-penetration and innovation-driven drivers, legal and market-driven drivers, fiscal incentives and market expansion drivers, personal branding drivers, sustainable advantage/power drivers and industrial and organizational promotion drivers. Rank agreement analysis exhibited varied levels of concurrence between professionals from developed and developing countries/jurisdictions.

The appreciation of the factors motivating ICJVs is beneficial to the successful implementation of ICJV strategies. A clear understanding of the drivers can help practitioners and policymakers to customize their ICJVs to reap the expected benefits.

The study has generated valuable insights into the factors that are greatly driving the implementation of ICJVs worldwide. While the findings of this study provide a profound contribution to theory and practice, it contributes to sustainable growth in different perspectives.

Construction tradesmen are exposed to high levels of stress that can worsen mental health, negatively impacting safety compliance and organization productivity. Hence, effectively coping with stress to prevent mental ill-health becomes an essential point of reference. Thus, this study aims to examine the role of factors such as resilience and coping strategies in protecting tradesmen against mental ill-health.

Using a cross-sectional survey design, 110 tradesmen from 65 construction companies were surveyed using the Patient Health Questionnaire, Generalized Anxiety Disorder, Brief Resilience Scale and Ways of Coping Questionnaire.

The results were analyzed using descriptive statistics and logistic regression analysis. With a 74.5%, 36.4% and 14.6% prevalence rate of self-reported depression, anxiety and suicide ideation among the tradesmen, only positive reappraisal, accepting responsibility coping behaviors and resilience would mitigate the likelihood of developing mental ill-health symptoms.

This study has extended existing literature by providing information vital to building interventions to deal with stressors effectively. This information would benefit individuals, organizations and the economy and equip policymakers with a deeper knowledge base toward improving mental health.
