A Critical Analysis of Risk Factors and Strategies to Improve Mental Health Issues of Construction Workers

Previous research has enabled construction professionals to consider appropriate mental health interventions for improved mental health outcomes. However, the heterogeneity of such interventions in contemporary studies makes it difficult for practitioners to keep up to date with relevant alternatives. Thus, the aim of this research is to critically analyse mental health risk factors and identify strategies intended to mitigate risks and promote employees' mental health in the construction industry. A Systematic Literature Review (SLR) was employed following PRISMA guidelines, and 58 articles that met the inclusion criteria were selected for data synthesis. In total, 100 risk factors and 76 preventive strategies were extracted and clustered into a taxonomy consisting of an individual level, workgroup level and organisational level. Strategies were further evaluated based on the type of prevention and financial significance. A critical content analysis of selected studies can suggest recommendations for future research, including the gap in mental health studies in the construction industry as well as the need for empirical research emphasis on generic forms of risks and strategies to cover more individual (e.g., age, profession), workgroup (e.g., team, trade, project) and organisational (e.g., culture, policy) factors that appropriately fit into construction workplace settings. The findings herein can broaden the mental health knowledge of industry practitioners, and could assist in mental health-related decision-making by developing best practices for boosting the mental wellbeing of the construction workforce.
