The MAP is a public domain research instrument and may be used free of charge for not-for-profit applications. Users are asked to cite the following reference when using the instrument : Marsden, J. Gossop, M. Stewart, D. Best, D. Farrell, M. Lehmann, P. Edwards, C. & Strang, J. (1998) The Maudsley Addiction Profile (MAP): A brief instrument for assessing treatment outcome, Addiction 93(12): 1857-1867.

Practicability / usefulness:

The MAP have been designed explicitly for outcome research purposes. All of the problem measures can be repeatedly administered at points during and after an index treatment episode. Changes in these measures can then be attributed to treatment or other processes over the intervening period. A key principle behind the MAP is that, as a core instrument, other measures and items can be added as required according to clinical, operational or research requirement. For example, a measure of drug dependence could be included, as well as questions concerning drug use history.


The manual of this instrument is included in the EIB as a relevant study about the MAP.
