metaSEM (version 1.4.0)

issp05: A Dataset from ISSP (2005)

Description

Thirty-two covariance matrices on work-related attitudes were extracted from the International Social Survey Programme 2005: Work Orientation III (ISSP, 2005). Seven variables were selected for demonstration purposes. They were grouped into three constructs: Importance of Job Prospects measured by job security (JP1), high income (JP2), and opportunity for advancement (JP3); Importance of Job Autonomy measured by work independently (JA1) and decide time of work (JA2); and Importance of Contributions to Society measured by help other people (CS1) and a job useful to society (CS2).
