Regardless of their lower salary, women are at least as satisfied with their salary as their male colleagues. Studies examining this ‘paradox of the contented female worker’ often used the Pay Satisfaction Questionnaire (PSQ). Whether this instrument is measurement invariant across gender, however, has not been previously tested. To avoid rash conclusions, the present study submitted PSQ data of 699 female and 448 male employees to a series of measurement invariance tests. The results supported the gender invariance of the measurement of pay satisfaction by the PSQ, assuring now that it is an appropriate instrument to examine the illustrated paradox.
