The present study considers the perspective of patients on MMT when assessing the outcomes of this treatment acknowledging the validity of this approach as an indicator. The primary aim of this study is to evaluate the concordance between improvement assessment performed by two members of the clinical staff a psychiatrist and a nurse and assessment carried out by MMT patients themselves. Method Patients n 110 and their respective psychiatrist n 5 and nurse n 1 completed a scale for assessing how the patient s condition had changed from the beginning of MMT using the Patient Global Impression of Improvement scale PGI-I and the Clinical Global Impression of Improvement scale CGI-I respectively. Results The global improvement assessed by patients showed weak concordance with the assessments made by nurses Quadratic-weighted kappa p and by psychiatrists Quadratic-weighted kappa p although in the latter concordance was statistically significant. The percentage of improved patients was significantly higher in the case of the assessments made by patients compared with those made by nurses vs. 80 Z-statistic p and by psychiatrists vs. 50 Z-statistic p . Conclusions MMT patients perception of improvement shows low concordance with the clinical staff s perspective. Assessment of MMT effectiveness .
