RESUMO
Objetive: To linguistically adapt and validate the Spanish version of the PEACH rating scale and identify the variables associated.Design: A transversal study of parents/guardians of infants and children with either normal hearing or hearing impairment.Study sample: The protocol included translation into Spanish and adapted linguistically. Regression models were constructed using logistic regression, obtaining the respective areas under the ROC curve. Validity was studied through an exploratory factor analyses and reliability analysis was carried out using Cronbach's Alpha.Results: The PEACH rating scale was carried out on 297 parents. There was a high degree of reliability for both children with hearing impairment (Cronbach's Alpha: 0.93) and for those with normal hearing (Cronbach's Alpha: 0.82). The exploratory factor analysis showed the existence of one factor (unidimensional). In relation to the variables associated with the global scores of the scale, the type of hearing loss and laterality impact on the score. The area under the ROC curve was 0.89, showing elevated sensitivity and specificity.Conclusions: The adapted version can be used to evaluate the effectiveness of amplification for infants and children with hearing impairment in Spanish-speaking children. The PEACH rating scale to Spanish has validity indicators similar to the original.
