Sexual addicts searching for treatment usually present severe sexual compulsivity (SC) in Brazil.Stressful events in childhood, which are common in Brazil, are often reported by sex addicts, and because of this, psychodynamic psychotherapy is a good choice of treatment. We aim to report the evolution of five sex addicts, who underwent short-term psychodynamic group psychotherapy (STPGP). Our specific goal is investigate the effect of the STPGP on SC. The five patients also had impulse control disorder or drug/ alcohol dependence, and were all Brazilian men over 18 years of the Institute of Psychiatry at Clinicas’ Hospital of University of São Paulo Medical School (HC-FMUSP). All of them met the Goodman’s criteria for sex addiction, and also reached scores up of the cut-off of the Sexual Compulsivity Scale (SCS) (= 24).
