Abstract

Objectives: To determine the changes in levels of work stressors in a nationally representative sample of Canadian workers from 1994/95 to 2000/01.

Methods: We compared responses for an abbreviated version of the Job Content Questionnaire in two waves of the National Population Health Survey (NPHS). Other items and scales related to work and health were also analyzed. Data were transformed to range from 0 to 10. Comparisons of the 2000/01 data were also made with the Canadian Community Health Survey (CCHS) conducted in 2000.

Results: There were only very small absolute differences between NPHS 2000/01 data and CCHS 2000 data. The NPHS comparison from 1994/95 to 2000/01 showed an increase in job security (change in means = 0.49, 95% CI 0.39 to 0.58) and a decrease in job physical demands (change in means = 0.45, 95% CI 0.35 to 0.54). Other changes in work characteristics were small in absolute value. The combined “overall work stressors” index dropped by 0.12 (95% CI 0.08 to 0.15).

Conclusions: Levels of work stressors did not increase over the period. Some subscales showed an improvement.

Résumé

Objectifs: Déterminer l’évolution des niveaux de facteurs de stress professionnel au sein d’un échantillon représentatif national de travailleurs canadiens entre 1994–1995 et 2000–2001.

Méthode: Nous avons comparé les réponses à une version abrégée du Job Content Questionnaire dans deux des cycles de l’Enquête nationale sur la santé de la population (ENSP). D’autres articles et échelles liés au travail et à la santé ont aussi été analysés. Les données ont été adaptées à une échelle de 0 à 10. Nous avons aussi comparé les données de 2000–2001 avec celles de l’Enquête sur la santé dans les collectivités canadiennes (ESCC) menée en 2000.

Résultats: Nous n’avons relevé que de très faibles écarts absolus entre les données de l’ENSP 2000–2001 et celles de l’ESCC 2000. En comparant les données de 1994–1995 et de 2000–2001 de l’ENSP, nous avons constaté une augmentation de la sécurité d’emploi (changement des moyennes = 0,49, IC de 95 % = 0,39–0,58) et une baisse des exigences physiques au travail (changement des moyennes = 0,45, IC de 95 % = 0,35–0,54). Les autres changements dans les caractéristiques de l’emploi étaient petits en valeur absolue. L’indice composite des «facteurs globaux de stress professionnel» a diminué de 0,12 (IC de 95 % = 0,08–0,15).

Conclusions: Les facteurs de stress professionnel n’ont pas augmenté au cours de la période à l’étude. Certaines sous-échelles font même état d’une amélioration.
