In the last years, the attention by public opinion and scholars towards the issue of precariousness has significantly increased in parallel with the instability and turbulences of the labour market. Understanding such phenomenon is now essential given its pervasiveness for an increasing and significant portion of the workforce, whence the aim of this study: to validate the short form of the Precariousness of Life Inventory (PLI-9). Seven hundred and twenty one temporary workers have been interviewed by means of a self-report questionnaire containing the PLI-9 and other convergent variables. Data, analyzed through explorative and confirmative factorial analyses, supported the three-dimensional structure of the questionnaire (i.e., indifference towards ones job, distrust toward the professional future and the emotional consequences on daily life). The analysis of convergent validity of the three dimensions, which exhibited satisfactory reliability indices, showed significant correlations with other constructs coherent with expectations. Finally, the criteria allow identifying temporary workers with high precariousness of life. The PLI-9 showed psychometric qualities that typify it, at the same, as a complete and concise tool for evaluating a phenomenon, such as precariousness of life, which affects (and plausibly will continue to do so), a significant portion of the active population.
