Abstract
Balancing individual capabilities with occupational demands and workplace stressors is necessary to reduce stress and prevent ergonomic and safety hazards. This is particularly true in occupations like construction that are characterized by numerous stressors, intense perceived overall demands, environmental factors, physical and mental loads, awkward postures, and organizational and personal factors in particular in Saudi Arabia. The current study proposes a subjective tool for assessing the impact of stressors on overall task demand (OTD). The analytic hierarchy process (AHP) was used to estimate the OTD and identify the factors that contribute to it. The OTD assessment tool survey participants were 524 male and was validated at actual construction worksites with 168 workers distributed among 7 jobs. The findings showed that OTD was significantly affected by occupational demands and identified a relationship among OTD, physiological measures and the NASA-TLX score. The proposed framework can help decision-makers and supervisors identify task demands, determine risk factors, and develop strategies for balancing job demands and worker capability.
