RESUMEN
OBJECTIVES: To translate and validate the Chinese version of the Speech, Spatial, and Qualities of Hearing Scale (SSQ) for children with hearing impairment (C-SSQ-C) and for their parents (C-SSQ-P). DESIGN: We translated the SSQ for children into Chinese and verified its readability and comprehensibility. A total of 105 participants with moderate-to-profound hearing loss (HL) and 54 with normal hearing were enrolled in the validation process. The participants with HL were fitted with bilateral hearing aids, bimodal hearing, or bilateral cochlear implants. The C-SSQ-P was administered to the parents of participants aged 3 to 6.9 years, and the C-SSQ-C was administered to participants aged 7 to 18 years. The internal consistency, test-retest reliability, and validity were evaluated for both questionnaires. RESULTS: Both C-SSQ-P and C-SSQ-C demonstrated high internal consistency (Cronbach's α >0.8) and good validity (generalized linear model revealed significant negative relationships between the C-SSQ-P subscales with aided better-hearing threshold [ß = -0.08 to -0.12, p ≤ 0.001] and between the C-SSQ-C subscales with worse-hearing threshold [ß = -0.13 to -0.14, p < 0.001]). Among the children with HL, the participants with bilateral cochlear implants had demonstrated better performance than those with bimodal hearing and bilateral hearing aids, as evidenced by the highest mean scores in three subscales. CONCLUSIONS: Both C-SSQ-P and C-SSQ-C are reliable and valid for assessing HL in children and adolescents. The C-SSQ-P is applicable in evaluating young children aged 3 to 6.9 years after a 7-day observation period, while the C-SSQ-C is appropriate for children and adolescents aged 7 to 18 years.
