Adaptation and validation of the Measuring of Treatment Adherence for mental health

Abstract

ABSTRACT Objective: to adapt culturally and validate the Measuring Instrument of Treatment Adherence for mental health. Method: methodological study, carried out with 300 individuals with mental disorders, in two Psychosocial Care Centers in Curitiba, state of Paraná, Brazil, from April to June 2014. The cross-cultural adaptation was developed according to international recommendations, the construct validation was made by exploratory factor analysis, and internal consistency was verified by Cronbach’s alpha. Results: through the evaluation of a committee of experts and completion of the pre-testing, face and content validation was achieved. From the factor analysis, we identified two factors of the instrument’s construct: involuntary action and voluntary action, with a total explanation variance of 55.7%. The value of Bartlett’s test of sphericity was p<0.001. Cronbach’s alpha was 0.74. Conclusion: the adapted and validated instrument proved to be trustworthy to be applied to the verification of adherence to drug therapy for individuals with mental disorders.
