The main unanswered question in the context of PWE is its relation to demographic variables. Relationships between PWE and demographic variables are still not clear. The current study aims to answer the research question: “How do demographic variables influence the Protestant Work Ethic?” To address this question, the thesis proposes a single-factor model of PWE, which is assessed on five demographic variables: formal education, age, family size, marital status, and religion. Groups were created for each of the five variables in order to assess their relationship with PWE. For the statistical analysis, multigroup structural equation modeling (SEM) was used and measurement invariance was evaluated in order to account for the differences between the groups. Based on the academic literature five hypotheses were created on the basis of model fit, factor loadings, and predicted factor scores. Only two of the hypotheses were partially supported (religion and family size) due to consistently higher factor loadings. Patterns were observed across most of the groups. Lower-educated participants exhibit distaste for leisure time, while more educated participants tend to be more hard-working. Religious people tend to endorse PWE less. Participants with more siblings endorse PWE more. Young participants tend to be more success-oriented, compared to single participants and middle-aged participants who are more hardworking. Future research should be focused on the area of demographics, the differences between religions in the context of a multidimensional factor model of PWE, and testing measurement invariance.Show less
