Abstract
Background
In past decades, the nature of work has undergone significant changes including increased psychological demands and job instability. A stressful psychosocial work environment has been shown to have adverse effects on workers' mental and physical health. This goal of this study is to estimate the prevalence of psychiatric syndromes and related disability in a populationโbased sample of employed adults and investigate associations between psychiatric syndromes and related disability.
Methods
A randomโdigit dial provincial wide mental health survey was conducted in Alberta, Canada (nโ=โ5,383). The telephone interview included the Mini International Neuropsychiatric Interview (MINI) and the World Health Organization's Disability Assessment Schedule (WHOโDASโII). In this analysis, participants who were currently employed were included (nโ=โ4,149).
Results
In this population, 6.2% had had at least one MINIโdefined psychiatric diagnosis with clinically significant interference. Without consideration of the clinical interference criterion, the prevalence of psychiatric syndromes was higher (33.5%). Psychiatric syndromes were strongly associated with disability. A doseโresponse relationship between the number of diagnoses and disability was found.
Conclusions
Interventional strategies in the workplace should focus on mental disorders at both the clinical and subโclinical levels. Am. J. Ind. Med. 49:514โ522, 2006. ยฉ 2006 WileyโLiss, Inc.
