Description

Eleven covariance matrices on work-related attitudes were extracted from the Inter-University Consortium for Political and Social Research (1989). Nine variables were selected by Cheung and Chan (2005; 2009) for demonstration purposes. They were grouped into three constructs: Job Prospects measured by job security (JP1), income (JP2), and advancement opportunity (JP3); Job Nature measured by interesting job (JN1), independent work (JN2), help other people (JN3), and useful to society (JN4); and Time Demand measured by flexible working hours (TD1) and lots of leisure time (TD2).
