Translation and cultural adaptation of the self-efficacy and their child’s level of asthma control scale: Brazilian version

Abstract

The aim of this study was to translate and adapt the Self-Efficacy and Their Child’s Level Asthma Control scale to Brazil’s cultural reality and evaluate the content validity of the Portuguese version. A methodological study that followed the stages: initial translation into Portuguese language by two independent translators; translation synthesis; translation of the scale’s synthesis back into its original English language (back-translation); pre-test of the final version with 30 parents/guardians and content validation. The pre-test evaluation led to modifications for the target population’s better understanding. Content validity obtained by means of analysis of the scale by the committee of experts was considered adequate (CVI>0.80). The scale’s application time with each participant ranged between 5-13 minutes. An increase in the scale’s application in Brazil is recommended, with the aim of improving its psychometric properties, as well as obtaining parameters for control and management interventions in childhood asthma.
