'Excessive workload as bad as joblessness'
The study is the first to use nationally representative data from England to compare the mental health of those who are unemployed with those in jobs of differing psycho-social quality.
Researchers led by Associate Professor Peter Butterworth from the Australia's National University said poor psychosocial job quality is measured by factors such as high job demands, low job control, poor job security and low job esteem.
Butterworth said the study's findings support the hypothesis that the mental health benefits of work are restricted to good quality jobs, and that the poorest quality work is comparable to unemployment as a risk factor for poor mental health.
"Our analysis clearly established that there was no difference in the rates of common mental disorders, such as anxiety and depression, between those who were unemployed and those who were in the poorest quality jobs," Butterworth said.
"Both of these groups of individuals were more likely to experience a common mental disorder than those who were in high quality work.
"Importantly, the results from this analysis of UK data confirm previous findings from analysis of Australian data. They add to a growing body of research highlighting the need to address the psychosocial aspects of the work environment as part of national government plans to reduce mental illness in the community," Butterworth said in a statement.
