Fonctionnement émotionnel et social des adolescents dépressifs, de leur fratrie et
d’un groupe témoin : étude transversale
Background: a negative cognitive bias is present among individuals who suffers from major depression. This bias is also reported among individuals at high risk of major depression (e.g. child of depressed mother). No study to date aimed to evaluate cognitive vulnerability of siblings of depressed individuals. Objectives: the present study aim to verify if siblings of depressed adolescents present a cognitive vulnerability that would predispose them to develop a major depression. Method: This study evaluates 49 adolescents (18 participants treated for depression, 16 siblings and 15 controls), aged between 12 and 20 years old. The cognitive vulnerability of every participant has been assessed using an auto-report questionnaire of symptoms (LEIDS-R) that evaluates cognitive reactivity and a task of facial recognition. Social cognition of participants is measured using the Movie for Assessment of Social Cognition (MASC) that we translated from german to french. Results: the preliminary analyses of this study concludes that a significant difference of cognitive reactivity is present between adolescents treated for depression and controls (p < 0.001). Conclusion: some of our results tend to confirm the presence of a cognitive vulnerability to depression among siblings of depressed adolescents. Those results are still preliminary and need to be confirmed by longitudinal studies.
