Change in Work Values and Norms among Dutch Young Adults: Ageing or Societal Trends?

In the present study, data were analysed longitudinally on the basis of lifespan developmental psychology to determine if work values and norms change as a result of ageing/maturation or societal trends (i.e. period effects between two measurement waves). Moreover, data were collected to determine if the younger participants showed more change than the older participants. Participants were three age groups, 18, 22, and 26 years old, respectively, in 1987 (N = 806). The participants completed a questionnaire in 1987 and 1991. Measures of work values and norms included Absolute Work Centrality, Relative Importance of Work, Obligation Work Norm, Emancipation Norm and Spare Time Norm, and Intrinsic, Extrinsic and Social Work Values. Using tests of differences in over time correlation coefficients, paired t-tests and analyses of variance, the results show that work, and especially intrinsic work values become more important by ageing than by societal trends and that younger participants indeed changed more than the older participants. These results underscore the plea of Schulenberg, Vondracek, and Kim (1993) for a combination of a developmental and individual difference perspective of work value change in career theory and practice.
