`titrebBEHAVIORAL PROBLEMS AT ADOLESCENCE : VIOLENCE, AGRESSIVENESS AND IDENTIFICATION`/titreb `!-- 755:'RESUME' --bIn the French classification of child and adolescent mental disorders (CFTMEA) the conduct disorders (listed in the DSM-IV) do not constitute a category in themselves. They are included in the psychopathic organization of the personality. The complexity of the etiopathogenic factors implicated in these troubles brings us to propose a variety of therapeutic indications : individual psychotherapy, parental support, reeducation and medication. The objective is to intervene both at the level of the symptom and at the level of the personality. A clinical example shows that therapy demands empathy and flexibility so as to get beyond negative transferential attitudes, agressive or self-destructive acting out. Certain moments of the therapy appear in detail where narcissism needs to be comforted, where we discover a need for dependance or a demand for limits.
