ABSTRACT
Purpose:
To evaluate the reliability of the results in an adapted version of the Brazilian Dizziness Handicap Inventory (DHI) adapted for children.
Methods:
1) semantic adaptation of DHI, first version, for child population; 2) appreciation of DHI by speech therapy judges for semantic appropriateness of the adapted version; application of the adapted version of DHI in 119 children with dizziness report; 4) application of DHI, adapted version, in 119 children suffering from dizziness symptoms; 5) test/re-test of 34 children.
Results:
In the group, there were higher average total scores in girls. There was no association between the scores of the Dizziness Handicap Inventory-Child/Adolescent (DHI-CA) and the age of the children. Adequate levels of internal consistency and stability of the results were verified in the full scale and the three subscales.
Conclusion:
DHI-CA appeared to be capable of reliably quantifying the impact of dizziness on quality of life of school-age children and adolescents, and the reliability of results is a first contribution to the validation of this instrument.
