Occupational stress and job demand, control and support factors among construction project consultants

• Investigates occupation stress and job demand, control and support factors.
• Uses hierarchical regression, factor analysis and structural equation modelling.
• Identifies job demand factors as the most critical job stressors.
• Calls for research into gender differences and management intervention techniques.

Occupational stress affects the health and wellbeing of people who work, and the construction industry is recognized as a high-stress working environment. The relationship between job demands, job control, workplace support, and experiences of stress in the South African construction context is investigated, using hierarchical regression, factor analysis and structural equation modeling to explore the strength of thirteen factor relationships with perceived stress. Data were gathered from an on-line questionnaire survey response sample of 676 architects, civil engineers, quantity surveyors, and project and construction managers. Predictors displaying a significant relationship with occupational stress are the presence of work–life imbalance, the need to ‘prove’ oneself, hours worked per week, working to tight deadlines, and support from line managers in difficult situations at work. Existing theories of occupational stress are confirmed but not completely supported. The construction industry should give attention to how the need to work long hours is justified. Organizations should look to improving managerial and collegial support for construction professionals, but be careful in engaging in socializing and project team-building activities. Further research will need to focus more deeply on construction-specific job demand factors; explore why women professionals appear to experience more stress than men; and aim to develop reliable early-warning detection techniques for construction professionals.
