Due to the dynamic and complicated construction process, multi-stakeholder involvement,the often tight and urgent time frame, and so on, construction industry has long been recognized as a stressful industry.In fact, stress is prevalent amongst construction professionals nowadays.Nearly 70% of construction professionals suffer from emotional stress, experiencing negative emotion, anxiety, depression, and so on.Physical stress,like headaches, back pain, allergy, and so on, is also not uncommon for them.However,stress is not necessarily bad.Stress can have positive or negative impact on performance,depending on the different work nature of individuals.Hence, this study aims to investigate the impact of stress on performance of construction professionals.To achieve this aim, a set of questionnaire survey was designed based on extensive literature review.A hundred and forty surveys were collected from construction professionals in Hong Kong, including construction project managers, architects, quantity surveyors,structural engineers, and so on.Data were analyzed by Pearson correlation and multiple regression modeling using SPSS version 19.Two types of stress (i.e., burnout and physical stress) and two types of performance (i.e., task and interpersonal performance) were identified.Results showed that both burnout and physical stress of construction professionals associate negatively with their interpersonal performance, which further affect their task performance.Results of the current study act as a platform for further qualitative study investigating the relationships in-depth.
