Measuring Item Validity and Reliability Psychosocial Factor with Human-Computer Interaction

Abstract

This research is motivated by the increasing attention to psychosocial factors as a crucial aspect influencing worker safety in the construction industry. The objective of this study was to formulate valid and reliable measurement items for psychosocial factors and to examine the influence of psychosocial factors on the safety performance of construction workers. This study employed a quantitative approach, collecting data through questionnaires from 154 construction workers at a large contractor company in Indonesia. The sampling technique used complex probability sampling with area sampling, and data analysis was performed using PLS-SEM using SmartPLS 3. The results indicate that of the six dimensions of psychosocial factors, only role ambiguity and individual autonomy significantly influence occupational safety performance, while work stress, work-family conflict, social support, and interpersonal conflict do not show significant effects. This study provides originality by integrating SEM analysis and a comprehensive mapping of psychosocial factors in the context of a large contractor, as previously discussed. The findings offer guidance for safety managers and policymakers to optimize the management of role ambiguity and enhance individual autonomy, as well as to conduct an in-depth evaluation of other dimensions that impact construction worker safety performance
