Attitudes Towards Buprenorphine and Methadone (Att-1)

May 28, 2009 updated by: Psychiatric University Hospital, Zurich

Attitudes of Patients With Opioid-Substitution and Their Therapists Towards and Buprenorphine and Methadone

Main intention of this study is to find out whether there is a difference between the attitudes towards opioid- substitution of opioid dependent patients under substitution with methadone, buprenorphine or without substitution and their therapists

Study Overview

Status

Unknown

Conditions

Intervention / Treatment

Detailed Description

Attitudes of patients and therapists can influence therapy success in both directions. Not much is known about patients' and their therapists' attitudes towards substitution medication. Our hypothesis is that the attitude towards buprenorphine is more positive than towards methadone even in patients taking methadone. Better knowledge about the influence of attitudes on treatment success could facilitate to adapt therapy to the patients' needs.
