Abstract: OBJECTIVE: The moderating role of personality traits between work
organization conditions and alcohol misuse by Canadian workers was
examined. PARTICIPANTS: Longitudinal data came from Statistics Canada's
National Population Health Survey (NPHS). METHODS: Data had a hierarchical structure and were analyzed using
multilevel logistic regression models. RESULTS: The multilevel analyis revealed that skill utilisation at
work increased by 7% the risk of being part of an alcohol misuse group.
Similarly, psychological demands at work, and being confronted with an
irregular work schedule increased alcohol misuse respectively by 69 and 611%.
Inversely, workers confronted with a job insecurity and those benefitting from
social support at work had a respective 12 and 5% lower risk of being part of
an alcohol misuse group. As for personnality traits, self-esteem increased by
17% the risk of alcohol misuse, while sense of coherence decreased the risk by
1%. Finally, self-esteem moderated by 3% the impact of physical demands at work
on workers'alcohol misuse. CONCLUSIONS: This study builds upon previous research, since no
prior study was able to identify the moderating role that self-esteem plays
between physical demands at work, and worker's alcohol misuse.
