Development and Psychometric Properties of the Job Insecurity Appraisals Scale (JIAS-6)

This contribution introduces the Job Insecurity Appraisals Scale (JIAS-6), a tool that measures job insecurity primary appraisals (i.e., challenge and hindrance). Starting from the transactional theory of stress and extending previous unpublished versions of the same scale, the authors developed JIAS-6, using two samples of Italian workers (N1 = 204 and N2 = 328). JIAS also addresses methodological and theoretical limitations of other primary appraisal scales. In Study 1, using a calibration sample, a series of confirmatory factorial analyses (CFAs) were performed and results showed that the final version of the scale fits the data well, while Study 2 findings (using a validation sample) replicated those obtained in Study 1 and provided support for strict measurement invariance across contract type, age, and gender, while scalar invariance was supported across job insecurity levels. Furthermore, we provided evidence of the relationship between job insecurity appraisals measured by JIAS-6 and other theoretically relevant constructs. The initial validation of JIAS-6 opens several new fruitful lines of research for job insecurity scholars.
