Professor Annie Vallières studies the social, psychological and cultural aspects of sleep problems. This approach allows her to better understand these disorders in a variety of contexts, including night workers, and in different countries and cultures.

Most night workers have difficulties sleeping. These problems have significant negative consequences: depression, illness, digestive problems, in addition to absence from work and a higher risk of accident. Many of these difficulties can be explained by the fact that these workers' schedules cause them to have to sleep at a time when their biological clock encourages awakening.

Dr. Vallières’s studies have shown that many night shift workers in the health care environment suffer from a sleep disorder, but that very few of them receive help. They have also identified aggravating factors that are as many intervention targets to improve the sleep of night workers. Among these factors, thoughts before falling asleep, job satisfaction and sleep-related behaviors, such as setting a sleep schedule, are important.

Dr. Vallières’s work helps develop behavioral intervention approaches adapted to the reality of night workers.

Approximately 33% of workers with non-standard working hours suffer from the Shift Work Sleep Disorder (SWD). It is associated with increased risk of depression, morbidity, gastric ulcers and an increase in absenteeism and the number of accidents at work. The sleep difficulties are mainly due to the fact that the work schedule brings night workers to sleep when their biological clock promotes wakefulness. However, it was suggested that psychological factors such as depressive symptoms or social factors such as job satisfaction, play a role in the evolution of these disorders. Our first study showed that 51% of night workers suffer from SWD and receive few help. Furthermore, this study identifies the importance of pre-sleep cognitive activation, job satisfaction, thoughts and sleep-related behaviours associated with bedtime routines in the presence of sleep disorders. The current study aims to deepen the conceptualization of SWD. The project studies specifically sleep, arousal and psychosocial status of night workers with or without sleep disorders. The effectiveness of interventions for SWD is studied. The expected results will provide new insights in the understanding of sleep disorders among night workers and provide a first behavioural intervention approach.

After postdoctoral internships at the Centre d'études des troubles du sommeil at Université Laval and at the Sleep Research Laboratory of the Sackler Institute of Psychobiological Research at the University of Glasgow (UK), Ms. Vallières joined the School of Psychology at Université Laval in 2006 as a regular professor. Specializing in clinical health psychology, particularly on sleep and the treatment of insomnia, she is developing a research program with two main components. The first component deals with sleep disorders associated with night shift work. The aim is to identify the psychological variables associated with these sleep difficulties and to develop a cognitive-behavioural treatment for this sleep disorder. The other component of this research program focuses on the socio-cultural aspects of sleep in collaboration with a team in Montreal and one in Buenos Aires, Argentina. It aims, among other things, to evaluate the influence of socio-cultural aspects on sleep habits, on the manifestations of insomnia symptoms, on chronotype (propensity to be alert), on complaints related to sleep difficulties and on the strategies used to cope with sleep difficulties. Her research projects are funded by the Canadian Institutes of Health Research and the Social Sciences and Humanities Research Council of Canada.
