To evaluate the relationship of cochlear implant-related factors with quality of life (QOL) outcomes in pediatric cochlear implantation (CI) recipients. In this cross-sectional study, data from 146 children who received CI before 7 years of age were collected. QOL was measured using the Children using Hearing Implants Quality of Life (CuHI-QoL) questionnaire. Auditory and language abilities were measured using categories of auditory performance II(CAP-II) scale and speech intelligibility rating (SIR) scale. The reliability and validity of the CuHI-QOL scale were tested using internal consistency tests and correlation analysis, respectively. Bivariate correlations were used to compare CuHI-QOL scores and educational placements to cochlear implant-related factors. QOL scores were further compared using ANOVA in different groups based on age at CI with different durations of implant use. The mean total CuHI-QOL scores was 60.13 (SD 8.97). The Cronbach's alpha of overall CuHI-QOL scale was 0.820. The CuHI-QOL total score was strongly to moderately correlated with CAP score (r = 0.542), SIR score (r = 0.545), duration of implant use (r = 0.403), and educational placement (r = 0.478). ANOVA showed the CuHI-QOL scores after 5 years post-CI were higher than those less than 2 years post-CI in children implanted ≤ 3 years of age. Good QOL could be obtained for children with CI and were significantly associated with young age at implantation, good auditory and speech abilities, speech rehabilitation training pre-CI, long duration of cochlear implant use, and mainstream educational placement.
