Research has found that people who work on temporary basis face an increased risk of mental health difficulties.
"Temporary workers-those lacking long-term, stable employment-seem to be susceptible to declining mental health for as long as they continue to work in these so-called 'disposable' or 'second class' jobs," said Amélie Quesnel-Vallée, a medical sociologist at McGill University and the study's primary investigator.
"This research shows that temporary work strains employee mental health, as contingent workers report more symptoms of depression and psychological distress than similarly employed workers who are not in these fixed-term positions," the expert added.
To reach the conclusion, the research team analyzed a sample of longitudinal records collected biennially between 1992 and 2002 from the U.S. National Longitudinal Survey of Youth 1979 (NLSY79). The NLSY79 is a survey of men and women born between 1957 and 1964 who were interviewed annually from 1979 to 1994, and biennially thereafter. The research team considered respondents' contingent (temporary) work status, depressive symptoms scores, poverty level and educational attainment.
The paper, "Contingent Work and Depressive Symptoms: Contribution of Health Selection and Moderating Effects of Employment Status," has been presented in the Parc 55 Hotel at the American Sociological Association's 104th annual meeting.
