Measuring job-satisfaction — FAQ

No, they differ significantly in what they measure and how they measure it. The JDI is quick and focuses on five core areas with a simple 'yes/no' response. The MSQ is more detailed, uses a scaled response to capture the intensity of feelings, and crucially distinguishes between intrinsic and extrinsic sources of satisfaction. Understanding these differences is vital for evaluating their appropriateness for different organisational goals and for critically analysing research that uses them.

This is a valid concern related to validity and reliability. Trustworthiness depends on the survey's methodology. If the survey is anonymous, administered by a neutral third party, uses well-designed, non-leading questions, and achieves a high response rate from a representative sample of employees, the results can be quite trustworthy. However, if employees fear their responses can be identified or if the questions are poorly worded, the results are likely to be skewed by social desirability bias and may not reflect true levels of satisfaction.

Not necessarily. The scores are not directly comparable because the scales and what they measure are different. A high score on the JDI indicates positive feelings about its five core facets. A high score on the MSQ provides a more nuanced picture, showing the intensity of satisfaction across many more items and distinguishing between intrinsic and extrinsic factors. An organisation might find the detailed intrinsic/extrinsic data from the MSQ more useful for designing job roles, while another might prefer the JDI's quick, simple snapshot to track general trends over time. The 'better' tool depends entirely on the organisation's specific objectives.
