Examining the effects of workstation design satisfaction, computer usage, supervisory and co-worker support on perceived physical discomfort and psychosocial factors

Abstract

This study examined the factors of computer use, job tasks, musculoskeletal and visual discomfort and organizational support to better understand the magnitude of their impact on the safety and health of computer work employees. A cross-sectional survey was administered to a large manufacturing company to investigate these relationships. Associations between these study variables were tested along with moderating effects framed within a conceptual model. Significant relationships were found between discomfort, computer use and psychosocial factors including supervisory relations moderating the relationships between workstation satisfaction and visual and musculoskeletal discomfort. This study provides guidance for developing recommendations in designing office ergonomic interventions with the goal of reducing musculoskeletal and visual discomforts while enhancing worker performance and their quality of worklife. © 2009 Springer Berlin Heidelberg.
