How to Measure the Psychological Contract? A Critical Criteria-Based Review of Measures

In this article we analyse the different ways in which psychological contracts are measured. On the basis of criteria for measurement and scale development psychological contract measurements are put to a test. The criteria are related to the way the measurement is developed and evaluated, and the specific conceptualisations of the content and evaluation of the psychological contract. Existing questionnaires to measure the psychological contract are evaluated. The use of psychological contract measurements of Freese and Schalk, Psycones, or Rousseau is recommended.
