Résumé (anglais)

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.
