Summary
This study validated a subjective underemployment scale, finding two dimensions of perceived overqualification. Further development and validation are recommended for this important measure of person-job fit.
Area of Science:
- Organizational Psychology
- Psychometrics
Background:
- The Subjective Underemployment Scale by Khan and Morrow (1991) is a key measure in understanding employee experiences.
- Assessing the dimensionality and measurement properties of existing scales is crucial for their reliable application.
Purpose of the Study:
- To extend and evaluate the dimensionality of the subjective underemployment scale.
- To assess the measurement properties of the scale across independent samples.
- To examine the relationships between overqualification dimensions and other work-related variables.
Main Methods:
- Confirmatory factor analyses were conducted on data from three independent samples.
- Correlational analyses were used to examine relationships with somatization, job satisfaction, and organizational commitment.
Main Results:
- Confirmatory factor analyses supported a two-dimensional structure for the scale.
- Measurement model parameters showed partial generalization across samples.
- Empirical support was found for most postulated relationships between overqualification dimensions and criterion variables.
Conclusions:
- The scale of perceived overqualification demonstrates a promising two-dimensional structure.
- Further development and validation in diverse samples are necessary for robust application.
- Findings offer insights into person-job fit dynamics and the impact of overqualification.
