L'enfance et l'adolescence in situ: facteurs environnementaux facilitateurs et inhibiteurs de troubles cognitifs et comportementaux

The definition of mental health associates three fundamental variables: biological variables, psychological variables and environmental variables. In this article, we will focus on environmental variables that inhibit and facilitate cognitive and behavioural disorders in childhood and adolescence. Environmental psychology considers the interrelations between human and environment in its spatial, social and chronological dimensions and considers it as a characterized and undissociated system. We will bring to mind social and physical environmental variables with which children and adolescents interact frequently and, through a literature review, we will enlighten environmental variables that are susceptible to induce behavioural disorders and psychological variables that modulate children's and adolescent's relations to environment. We then suggest possible outcomes of this approach in clinical practice as well as in terms of therapeutic applications in child psychology and psychiatry. Finally, we evoke the necessity of taking in account neurobiological fields in order to outline a model of human development integrating the three variables that define mental health. © 2012 Société française de psychologie.
