Validation of an instrument for the evaluation of adolescents' knowledge about Hansen's disease

Abstract

Objective: To construct and validate instruments for the evaluation of adolescents' knowledge about Hansen's disease and characterization of these subjects. Methods: Methodological study developed in three steps, namely: construction of instruments; face and content validation with seven judges; and semantic validation with 20 adolescents aged from 10 to 14 years. Results: There was more than 80% agreement among judges in all domains, items and components evaluated. The general agreement among judges for the instrument for evaluation of adolescents' knowledge on Hansen's disease with 14 items was 89%, and for the instrument for characterization of participants with 17 items, agreement was 93%. In the semantic validation, the instruments were considered of good understanding, and there were no difficulties for completing them. Among adolescents, 10% reported having or having had cases of Hansen's disease in the family. Most adolescents (55%) had never heard of or received information about Hansen's disease, and most (60%) also said they did not know what Hansen's disease was. Conclusion: The instruments constructed to evaluate adolescents' knowledge about Hansen's disease and to characterize the studied population were considered valid regarding face, content and semantics. The appearance, comprehension and relevance were considered as very good or excellent in both instruments, and they can be applied to the target population.
