Stress among South African construction professionals: a job demand-control-support survey

摘要

Research into workplace stress in the construction industry has been dominated by studies undertaken in Hong Kong, England and Australia, with relatively little attention having been paid to African countries. A purposively selected sample of thirty-six construction professionals (comprising architects, project managers, construction managers, engineers and quantity surveyors) based in Cape Town, South Africa, were surveyed regarding their perceptions about, and experiences of, workplace stress. The purpose was to identify and rank job demand, job control and job support factors and to analyse these by gender and professional grouping, both in terms of how respondents perceived them, as well as in terms of how frequently they had experienced them. The main finding was that respondents' perceptions about the importance of job demand, job control and job support factors were largely consistent with their own experience of these factors. Distinguishing between perceptions and experience of stressors and moderators of stress was, however, considered valuable because the fact that differences were found indicates the need for precision in the design of scales. The highest ranked factors were, respectively, 'critical time constraints', 'volume of work' and 'adequate compensation (salary)'. Women and men ranked items differently, as did the various professional groups. The main conclusions were that the construction project environment is a time-pressured, complex, environment in which work-life balance is negatively affected, particularly for women. Control over the type, flow and volume of work were perceived to be the main moderators of stress, whilst salary and career path opportunities were perceived to be the main job support moderators of stress. The applicability of using the job demand-control-support framework was confirmed given that the main stressors, control and support moderators were found to be to be largely consistent with the findings of previous studies. Future research taking a gendered approach should anticipate issues important to female respondents and should consider the benefits of qualitative methods. The design of research focusing on construction professionals should consider using the project team as the unit of analysis to ensure that the influence of the interconnected-ness of participants' roles is taken into account.
