The Job Insecurity Scale: A psychometric evaluation across five European countries

Multiple instruments have been developed and used to measure quantitative job insecurity (i.e., insecurity to lose the job as such), often without systematic evaluation of their psychometric characteristics across countries and language barriers. This may hamper consistent and reliable cross-study and cross-country comparisons. This study's aim was to introduce and validate the four-item Job Insecurity Scale (JIS) developed by De Witte across five European countries (i.e., Belgium, The Netherlands, Spain, Sweden, and the UK). Overall, the results demonstrated the construct validity (i.e., configural invariance and invariance of the measurement model parameters), the reliability (internal consistency of the items), and the criterion validity (with respect to affective organizational commitment, perceived general health, and self-reported performance) of the JIS. The different translations of the JIS can thus be considered as valid and reliable instruments to measure job insecurity and can be used to make meaningful comparisons across countries. Furthermore, the JIS translations may be utilized to assess how job insecurity is related to outcomes.
