Demystifying moderate variables of the interrelationships among affective commitment, job performance, and job satisfaction of construction professionals

Project goals expressed in terms of time, cost, and quality requirements are seldom disputed. However, it is not easy to ensure that the defined goals will be implemented by all parties involved in the implementation process as goal commitment is one of the key variables in project success and participant satisfaction in construction projects. In order to ensure professional commitment in the management process and optimize construction performance in the complex situation, it is necessary to identify the moderate variables and clarify the interactions among affective commitment, job performance, and job satisfaction of construction professionals. A questionnaire survey was conducted in Hong Kong. Both correlation analysis and hierarchical regression models were applied. The results revealed that both job acceptance/contribution and specificity/teamwork are moderate variables influencing the relationships between affective commitment and job performance and between job performance and job satisfaction. A series of conditional relationships is revealed in detail in this study and some suggestions, such as formal briefing sessions, regular formal meeting, and value engineering workshop, are recommended.
