Conversive disorders among children and adolescents: towards new "complementarist" paradigms?

This paper aims to describe current questions concerning conversive disorders among children and adolescents. We first describe prevalence and clinical characteristics of these. Many unresolved questions remain. Why do patients show excess, or loss of function? Attachment theory offers a relevant framework to answer this question. Does neurobiology of conversion disorders shed light on conversive processes? Current neurobiological research paradigms focus on the symptom, trying to infer processes, instead of proposing paradigms that test theoretical hypotheses. The most convincing theoretical framework that has already proposed a coherent theory of conversion is a psychodynamic one, which has not yet been tested with neurobiological paradigms. The interest of studying child and adolescent conversive disorders is to provide a means to more deeply investigate the two challenges we face: theoretical, and clinical ones. It provides the opportunity to access a pathopsychological process at its roots, not yet hidden by many defensive, rationalizing attitudes, and to better explore environmental features. We propose a "complementarist" model, which allows the combination of different approaches (neural, cognitive, environmental, attachment, intra-psychic) and permits proposal of different levels of therapeutic targets and means.

[French translation and validation of Izard's differential emotion scale. Study of the verbal qualification of emotions]

This work presents the validation of a French version of the emotional self rating scale by Izard (Differential Emotion Scale). This scale is based on the theory of the Discrete Emotions which proposes the existence of ten fundamental emotions. This self-rating scale consists of thirty emotional adjectives (three for each emotion). The validation was done by using a non inductive method (by asking the subject to describe his present emotional state) with 84 control subjects. It shows that this version is valid. Main results are first the binarisation of the emotions (positive and negative), then the existence of complex factors with psychopathological meaning after factorial analysis. These results are in agreement with a theory of expressive emotional levels more than with the theory of discrete emotions in psychopathology.
