Abstract
Job involvement–alienation was studied over three time points with a sample of undergraduate engineers undergoing a career transition from university to paid employment. Data from Newton and Keenan (1991) were re-analysed under a latent growth curve modelling (LGCM) perspective, in order to provide an alternative analysis of the development of job involvement across that situational change, and to test the hypothesis that job involvement actually changed over that time period. University course satisfaction and anxiety were included as time-invariant predictors of growth, and compared to ascertain whether there would be differential effects of both predictors. The results supported the hypothesised relationships, indicating a significant growth in job involvement–alienation over time, with course satisfaction and course anxiety showing an equivalent impact on its change trajectory.
I don't pretend to understand all the mathematics and statistical analyses involved – I left most of that behind me 30+ years ago and I don’t remember ever having learned about “latent growth curve modelling”. Despite that I found that the results and discussion made sense.
