[Russian version of PEACH scale (validation and normative data)].

PEACH is an important tool for evaluation of children's hearing development, used in age 2-7 years. It is also appropriate for amplification outcomes measurements. PEACH scale includes 13 questions. Parents fill the questionnaire after week observation of child's hearing behavior in different situations. The goal of the study was validation of Russian version of PEACH scale. Translation and cross-cultural adaptation were performed following international guidelines. 50 children with normal hearing and 50 hearing impaired children were involved in the validation process. All of the hearing-impaired children used hearing aids or cochlear implants. PEACH scores of the children with normal hearing have strong correlation with data of original version (ρ=0.998; <0.05) and can be used as a normative data for Russian version. PEACH scores of the hearing-impaired children were worse in higher degrees of hearing loss, which shows sensitivity of the method. Test-retest reliability in children with normal hearing was ρ=1.0 (<0.05), in hearing impaired children ρ=0.976 (<0.05).
