[Effectiveness of psychotherapy in asthma: meta-analysis].

Abstract

Various works have been done to find the efficiency of different psychotherapies of asthma. The results are sceptical and sometimes contradictory; this contradiction probably is due to the multiple methods or also to the various variables linked to the illness. The results of our meta-analyses on 74 hypotheses chosen by specific criteria show the efficiencies of all these psychotherapies in asthma; however, these results are largely dependent on the 8 variables taken into account.
