Thérapies comportementales et cognitives et troubles de l’humeur

Abstract

A large number of psychotherapies were proposed to depressed patients. The behavioural and cognitive therapies showed their efficacity. This short-term therapy improves quickly the symptoms and prevent around 30% of relapse. Many patients having suffered from depression undergo unipolar depression relapses during the 5 years following the treatment. Therefore international guidelines, including pharmacological and psychological interventions, were published to prevent these relapses. Nowadays a combined treatment is most often prescribed. This paper presents the behaviour and cognitive models of depression. This brief psychotherapy works on the depressed symptoms (engaging the patients in a large number of pleasant activities), on hopelessness cognitions and on the own psychological vulnerability (named cognitive schemata). The activation of depressed schemata is correlated with relapse. The indication of TCC in depressed patient is discussed after two ou three sessions (“case conceptualisation”) performed by a cognitive and behaviour therapist. This professional has preliminary learnt the theory and practice during a specific training. This article reviews main studies including the cognitive and behavioral therapy in depressed uni- and bipolar patients. Results are discussed in terms of acceptability, feasibility, and efficacy. A case study confirms the relevance of this approach. New cognitive and behaviour programmes were developed during 20 years with recurrently depressed patients, these included additional booster sessions sometimes combined with well-being therapy and even with mindfulness-based cognitive therapy. The new approaches were assessed in pilot studies and their results will have to be confirmed.
