Early Speech Development in Romanian Children with Cochlear Implants Assessed Using the LittlEARS® Early Speech Production Questionnaire (LEESPQ)

<b>Objective:</b> The aim of the study was to evaluate the validity, clinical applicability, and developmental sensitivity of the Romanian LEESPQ in children with cochlear implants (CIs), by analyzing its association with age at implantation, duration of auditory experience, and implantation laterality, and by comparing the developmental trajectory with that of normal-hearing (NH) children. <b>Methods:</b> The study assesses the validity, reliability, and clinical sensitivity of the LEESPQ in pediatric cochlear implant users. Furthermore, it investigates the associations between total questionnaire scores and key clinical variables, including implantation laterality (unilateral versus bilateral), age at device activation, and duration of implant use. Forty-seven children with CIs (26 boys, 21 girls) were included, with implantation ages ranging from 9 months to 5 years. Of these, 21 received unilateral implants and 26 bilateral implants. Responses were analyzed both in relation to clinical variables and in comparison with available normative data from NH children, in order to delineate potential differences in linguistic developmental trajectories. <b>Results:</b> Findings suggest that the LEESPQ is a reliable and clinically valuable instrument for monitoring post-implant linguistic progress. It provides relevant insights into early auditory access, the linguistic environment within the family, and the development of early verbal production. Scores were significantly influenced by age at implantation and duration of auditory experience, confirming the role of early stimulation and neural plasticity in shaping speech development after cochlear implantation. <b>Conclusions:</b> The LEESPQ demonstrates strong clinical utility as a sensitive tool for monitoring early preverbal and verbal development in children with CIs. By capturing score variations associated with age at implantation, auditory experience, and implantation laterality, the questionnaire provides meaningful insights into early post-implant outcomes and supports individualized rehabilitation planning. These findings highlight the value of the LEESPQ for early outcome assessment in pediatric cochlear implant users.
