[Translation to portuguese and validation of the Diabetes Quality Of Life Measure (DQOL-Brazil)].
OBJECTIVE
To evaluate the psychometric properties of Brazilian version of Diabetes Quality of Life measure (DQoL-Brazil).


METHODS
The DQOL was translate to Portuguese, following a recommended protocol, and applied to 121 subjects (56.2% females) with average diagnostic to type 2 diabetes of 8.1 (SD=7.13) years, (range 32-89 years old).


RESULTS
The translated measure showed high internal consistency (Cronbach's alpha = 0.92). A positive correlation (p < 0.01) was found between all the items and their scales and the total score of instrument, except in the items 18 and 35. These items were excluded from the translated version of DQoL. In concurrent validity analysis, patients with HbA1C higher than 9% presented a significantly higher (p = 0.01) total score for DQoL.


CONCLUSIONS
DQoL-Brazil presents reliability and validity to be used in type 2 diabetes adult patients.
