Aim. To develop a brief, multi‐dimensional instrument for assessing treatment outcome for people with drug and/or alcohol problems. The Maudsley Addiction Profile (MAP) is the first instrument to be developed in the United Kingdom for this purpose. Design. Field testing with quota‐recruitment of problem drug users and problem alcohol users in treatment with researcher and clinician‐administered test‐retest interviews. Setting. Two community and two inpatient services at the Bethlem Royal and Maudsley Hospital, London. Participants. Subjects (160 drug users and 80 alcohol users) interviewed by eight interviewers (four researchers and four clinicians), each of whom interviewed 30 subjects on two occasions. Measures. Sixty items across substance use, health risk, physical/psychological health and personal/social functioning domains. Findings. Average completion time of the MAP was 12 minutes. The questionnaire was acceptable to a majority of subjects and performed well with both researcher and clinician interviewers. Internal reliability and feasible concurrent validity assessments of the scales and items were highly satisfactory. Test‐retest reliability was good, average intraclass correlation coefficients across eight substances were 0.94 and 0.81 across health risk, health problems, relationship conflict, employment and crime measures. Conclusions. The MAP can serve as a core research instrument with additional outcome measures added as required. The collection of a set of reliable quantitative measures of problems among drug and alcohol users by research or treatment personnel for outcome evaluation purposes need not be time‐consuming.
