development of persian version of teachers’ evaluation of aural/oral performance of children scale

Background and aim: teachers’ evaluation of aural/oral performance of children (teach) scale is one of the scales used for assessing hearing-impaired children’s behaviors in reallife environments, regardless of the degree of hearing loss. the aim of the present study was development, determining validity and reliability of the persian teach (p-teach) in normal-hearing and hearing-impaired children. methods: the teach scale was translated and cross-culturally adapted. after verifying the face validity of the scale, p-teach was performed on 40 normal-hearing and 42 hearing-impaired and its’ results were compared with the persian parents' evaluation of aural/oral performance of children (p-peach). the test-retest reliability of p-teach was evaluated after two weeks on 10 subjects who were selected randomly. results: content validity index for item 3 was 0.8 and for others were 1. p-teach scores showed a significant difference between two groups (p < 0.001). there was a strong correlation between p-teach and p-peach scores (r = 0.59 to 0.87; p < 0.05). cronbach's α for p-teach was 0.75 -0.98 for both groups. there was a significant correlation between children’s age and total score of p-teach in normal-hearing and hearing-impaired children (r = 0.40 and 0.41 respectively; p ≤ 0.001). there was a significant correlation between test and retest of p-teach (r = 0.87 to 0.97; < 0.001). conclusion: p-teach is a well-adapted valid and reliable tool for functional evaluation of the auditory performance of hearing-impaired children. the study showed that the p-teach has a strong agreement with the p-peach.
