This study describes the development and validation of two scales measuring job security: the Job Security Index (JSI), measuring an individual's cognitive appraisal of the future of his or her job with respect to the perceived level of stability and continuance of that job, and the Job Security Satisfaction (JSS) scale, measuring employee satisfaction with a perceived level of job security. Item response theory and classical test theory analyses indicate that the scales are highly reliable and exhibit good discriminant and criterion‐related validity. Future researchers are advised to apply confirmatory factor analysis (CFA) to the scales to confirm their factor structures.
