“…Virtanen et al's (2005) meta-analysis of 27 studies found an association between temporary employment and psychological morbidity, although the magnitude of the health risk depended on the degree of instability of the temporary employment, as well as on the context. Similarly, Artazcoz, Benach, Borrell and Cortes (2005) reported that the strength of the association increased with the degree of insecurity of the contractual arrangement, and varied across gender and social class. More recent studies also showed that temporary contracts were associated with negative psychological outcomes, even after accounting for potential selection effects (Cottini & Lucifora, 2010;Pirani & Salvini, 2015;Quesnel-Vallée, DeHaney, & Ciampi, 2010;Waenerlund, Virtanen, & Hammarström, 2011).…”
