Anxiété-trait, stress perçu et symptômes somatiques chez les doctorants

Abstract : While the quality of life and the mental health of undergraduate students have been the object of numerous studies which show that the latter is generally worrisome (depression, anxiety, sleeping disorders, suicidal ideas, etc.), therer are few publications dealing with advanced students, those registered in a Master's degree or in a PhD. This work examines the relations between trait-anxiety, perceived stress and somatic symptoms within a wide sample of French PhD students, as well as the influence on perceived stress of sociodemographic, environmental and behavioral factors (physical activity in particular), in order to have a better understanding of this population's specificities. It is mainly based on three validated scales: the State-Trait Anxiety Inventory, Y-form, by Spielberger (1969), the Perceived Stress Scale by Cohen et al. (1983) and the Psychosomatic Index of the SCL-90-R by Derogatis (1994). The results confirm those of previous studies. They show that female PhD students present a higher vulnerability to trait-anxiety and perceived stress than their male counterparts and that there is a strong correlation between trait-anxiety and perceived stress. Besides, almost one fifth of the participants obtain a score of perceived stress superior to the pathological threshold. The study also demonstrates the mediator role of perceived stress in the relation between traitanxiety and somatic symptoms, on the one hand, in the relation between physical activity and somatic symptoms, on the other hand. Finally, seven variables play a significant role in the prediction of perceived stress: sex, age, number of years after PhD registration, support by a psychologist, a psychiatrist or a psychotherapist in the past, present therapeutic support, physical activity and sleep quality.
