Background and Aim: Early communication skills in children with hearing loss depend on the quantity and quality of information received from parents. The present study aimed to investigate the effectiveness of early communication skills training in developing the communication skills of infants and toddlers with cochlear implants. Methods: To this end, 54 infants and toddlers at the age range of 8–24 months with sever to profound hearing loss fitted by Cochlear Implant (CI) with their mothers participated in this study. The experimental and wait list control groups had auditory verbal therapy as the main intervention after the CI; however, the experimental group received a systematic early communication skills program. All subjects were assessed using the Communication and Symbolic Behaviour Scales Developmental Profile as the pre-and post-tests. Results: Multivariate analysis of covariance indicated the effect of systematic training on the early communication development of subjects in intervention group. Conclusion: Teaching the parents how to interact with infants and toddlers with CI could improve the communication skills of the infants and therefore it’s recommended to be included in the auditory rehabilitation programs.

Background and Aim: Clinicians and researchers always need standard measures for the evaluation of auditory perception and speech production in deaf children, particularly those with cochlear implants. This study addresses the reliability and validity of the Persian version of categorization of auditory performance (CAP) scale and speech intelligibility rating (SIR) in cochlear-implanted prelingual deaf children. Methods: A total of 92 cochlear-implanted deaf children aged 1.3-15.7 years participated in the study. Test-retest reliability, inter-rater reliability, and criterion and construct validity of the scales were investigated. Results: The obtained test-retest reliability for categorization of the auditory performance scale and speech intelligibility rating was 0.82 and 0.99 (p<0.01), respectively, whereas the suggested inter-rater reliability based on average Cohen's kappa coefficient was 0.73 and 0.70 for the two scales (p<0.01), which appear acceptable. The concurrent validity of the scales was 0.64 and 0.69 (p<0.01). The construct validity for categorization of the auditory performance scale ranged between 0.58 and 0.74 (p<0.01), whereas the same feature for the speech intelligibility rating indicated a range between 0.66 and 0.69 (p<0.01). Conclusion: The findings of this investigation indicated that both CAPII and SIR scales are reliable and valid instruments for the assessment of auditory perception and speech production of cochlear-implant deaf children.

Spatial ability is known to have an important role in learning different skills in childhood and achieving success in specific professions. A vast majority of the studies on this topic have focused on adults, and few on in children. In this study, eight tasks were selected to assess eight factors of spatial ability and were modified to be suitable for children. Computerized versions of the tasks were designed and their reliability was measured. One-hundred and ten Iranian children aged 9 to 12 years old participated in the study. In order to assess the test-retest reliability, half of the participants were tested twice. Internal consistency reliability was calculated for some of the tasks. Intraclass correlation coefficients were obtained by test-retest reliability analysis for all tasks ranging from 0.689 to 0.997. The range of Cronbach's a coefficient was found to be between 0.335 and 0.784. The range of the ω coefficient was from 0.428 to 0.798. Each modified task had adequate reliability for assessing the respective spatial ability factors. This battery can help to identify the level of spatial performance in children. [ABSTRACT FROM AUTHOR]
