Dimensionality, Reliability and Validity of a Multidimensional Job Insecurity Questionnaire. Preliminary Findings in the Italian Context
Keywords:job insecurity questionnaire, validation, dimensionality, measurement invariance
AbstractJob insecurity is considered one of the major work stressors in the contemporary working life. Despite a long tradition of research, to date many questions about job insecurity are still open, including those regarding its measurement model. The present study aimed to introduce a Multidimensional Job Insecurity Questionnaire (MJIQ) and provide support for its psychometric properties. The MJIQ was composed by 20 items and is aimed at offering a complete and balanced assessment of job insecurity in its major dimensions (i.e. quantitative and qualitative) and narrow facets (affective and cognitive). Participants were employees from private and public Italian organizations (N=405). Results of Exploratory Factor Analysis supported the emergence of two major dimensions, namely quantitative and qualitative job insecurity. The invariance of the measurement model tested via Multi-group Confirmative Factor Analysis showed that the MJIQ parameters were invariant across gender. The two major dimensions of job insecurity evidenced good reliability and strong concurrent validity with well-known job insecurity outcomes. Overall, these preliminary results show that MJIQ is a reliable and valid measure to tap the complexity of the job insecurity construct.
