This paper examines the possibility that clinicians working in an alcohol and other drug (AOD) treatment service may lack appreciation of problem improvement in clients who choose to dropout against clinical advice. Underlying this investigation is the belief that if clinicians are indeed unperceptive of problem improvement amongst this population then this may explain why retention based responses to client dropout continue to be promoted, despite evidence to suggest that they are ineffective and/or unnecessary. Outcome data obtained from a sample of 75 AOD treatment clients and their respective clinicians at baseline and 2-month follow-up are reported. Analysis of these data suggest a client/clinician discrepancy in perceived problem improvement was evident in the study setting: clinicians reported significantly less problem improvement in the first 2 months of service attendance as compared to their clients and this discrepancy was most pronounced if the client had dropped out of treatment.
