New European instruments for treatment outcome research: reliability of the maudsley addiction profile and treatment perceptions questionnaire in Italy, Spain and Portugal.
This report describes the field testing of two recently developed instruments for treatment evaluation research - the Maudsley Addiction Profile (MAP) and the Treatment Perceptions Questionnaire (TPQ) - in Italy, Portugal and Spain. The MAP and TPQ have been developed in the United Kingdom as brief instruments which contain measures of high face validity for research applications with the adult psychoactive substance use disorder population. The present study assesses the application of these instruments in the continental European context and assesses the internal and test-retest reliabilities of the items. A total of 206 subjects participated in the study (124 subjects participated in the MAP test-retest study, and 95 clients completed the TPQ). Thirteen subjects completed both the MAP and the TPQ questionnaires. Results of the study indicated that the MAP can be administered to clients in 15 min or less. The internal and test-retest reliabilities of the MAP and TPQ are satisfactory. Both instruments are suitable for treatment evaluation and other relevant research purposes in the European Union.
