Music therapy could be defined in a simple way as a process of assessment and treatment that uses musical techniques and experiences, on which the assessment allows not just establish goals and objectives, but also check whether they were reached. There is a lack of studies and publications on validation of evaluation instruments in music therapy in Brazil. Hence, the objective of this academic study was translating and validating a specific instrument of music therapy for use in Brazil: the Individualized Music Therapy Assessment Profile (IMTAP). The translation and validation of IMTAP were done through a transversal study, where have been analyzed the psychometric properties of contents of validity, convergent validity and agreement among evaluators. The evidences of content validity were considered acceptable, demanding just a few adjustments during the final translating revision. A fair correspondence between evaluators have been detected (intraclass correlation coefficient, ICC, of 0.98) indicating good conditions of IMTAP acceptance. Regarding to convergent validity, we found negative moderated correspondences on comparison between expressive communication IMTAP (vocals idiosyncrasy) and CCC verbal scale (r=-0.519) and non verbal (r=-0.468). The methodology used at translation’s process and psychometric properties observed during the studies of validation leads to admit an IMTAP's Brazilian version for use in Brazil.
