“…This scale was however, not used in any of the studies included in the review, implying that it has not been as widely used and researched with children who are DHH. The benefits of this scale are that its psychometric properties have been researched and found to be good in various languages and situations: for example: Fijian ( Hopf et al., 2017 ), Swedish ( Lagerberg et al., 2019 ), Korean ( Lee, 2019 ), Cantonese ( Ng et al., 2014 ), Vietnamese ( Phạm et al., 2017 ), Italian ( Piazzalunga et al., 2020 ), Jamaican Creole ( Washington et al., 2017 ), and German ( Neumann et al., 2017 ). It has similar disadvantages as the SIR scale being a subjective measure, and if this scale were to be used with children who are DHH, further research would be needed to assess its qualities for that specific group.…”

There is great variability in the ways in which the speech intelligibility of d/Deaf and hard-of-hearing (DHH) children who use spoken language as part, or all, of their communication system is measured. This systematic review examined the measures and methods that have been used when examining the speech intelligibility of children who are DHH and the characteristics of these measures and methods. A systematic database search was conducted of CENTRAL; CINAHL; Cochrane; ERIC; Joanna Briggs; Linguistics, Language and Behavior Abstracts; Medline; Scopus; and Web of Science databases, as well as supplemental searches. A total of 204 included studies reported the use of many different measures/methods which measured segmental aspects of speech, with the most common being Allen et al.’s (2001, The reliability of a rating scale for measuring speech intelligibility following pediatric cochlear implantation. Otology and Neurotology, 22(5), 631-633. https://doi.org/10.1097/00129492-200109000-00012) Speech Intelligibility Rating scale. Many studies included insufficient details to determine the measure that was used. Future research should utilize methods/measures with known psychometric validity, provide clear descriptions of the methods/measures used, and consider using more than one measure to account for limitations inherent in different methods of measuring the speech intelligibility of children who are DHH, and consider and discuss the rationale for the measure/method chosen.

“…A considerable amount of research has focused on evaluating different psychometric properties of translated versions of the ICS and describing the ICS composite scores of typically developing children, children whose parents had concerns about speech, and/or children with speech-language disorders ( Hopf et al, 2017 ; Kim et al, 2016 ; Kok & To, 2019 ; Lagerberg et al, 2021 ; Le et al, 2021 ; Lee, 2019 ; Leon et al, 2021 ; Lousada et al, 2019 ; Neumann et al, 2017 ; Ng et al, 2014 ; Phạm et al, 2017 ; Piazzalunga, Salerni, Ambrogi, et al, 2020 ; Piazzalunga, Salerni, Limarzi, et al, 2020 ; Washington et al, 2017 ). Mean ICS composite scores reported from studies that included children who speak English and other languages are summarized in Appendix Table A1 .…”

“…Only a few studies have reported the range of ICS composite scores of typically developing children; however, none of the existing studies included children who spoke English ( Hopf et al, 2017 ; Piazzalunga, Salerni, Ambrogi, et al, 2020 ; Piazzalunga, Salerni, Limarzi, et al, 2020 ; Van Doornik et al, 2018 ). Across these studies, the range of ICS composite scores was between 2.86 and 5 for children aged 3;0–10;5.…”

“…Although the ICS is a widely used clinical tool, available normative data for English-speaking children are limited to Australian English–speaking children aged 4;0–5;5 ( McLeod et al, 2015 ). Other available data sets that describe ICS composite scores for specific age groups are on bilingual children speaking English and Jamaican Creole aged 3;3–6;3 ( Washington et al, 2017 ), Cantonese-speaking children aged 2;4–6;9 years ( Kok & To, 2019 ), European Portuguese–speaking children aged 3;10–6;2 ( Lousada et al, 2019 ), Italian-speaking children aged 3;0–5;11 ( Piazzalunga, Salerni, Ambrogi, et al, 2020 ), Swedish-speaking children aged 3;2–9;2, ( Lagerberg et al, 2021 ), and Vietnamese-speaking children aged 2;0–5;11 ( Phạm et al, 2017 ). Reported mean ICS composite scores for specific age bands are summarized in Appendix Table A2 .…”

Purpose: The aim of this study was to quantify the clinical utility of the Intelligibility in Context Scale (ICS) English version by characterizing the growth patterns of the ICS composite scores and seven ICS individual item scores of typically developing American English–speaking children. Method: Parents of 545 typically developing children aged 2;6–9;11 (years;months) completed the ICS. Using a proportional odds model, we regressed ICS composite scores on age and computed for model-estimated mean and lower quantile ICS composite scores. Logistic regression and proportional odds modeling were utilized to quantify the relationship of individual ICS items and age. Results: ICS composite scores of typically developing children changed with age, but change was small and incremental, with scores compressed between 3 and 5 across the range of ages. An average child (i.e., on the 50th percentile) is expected to have an ICS composite score of 4 beginning at 3;0 and an ICS composite score of 5 by 6;6. On average, parents gave different intelligibility ratings based on communicative partners, and the rating differences between communicative partners decreased with age. Conclusions: Given that ICS scores increase with age, the expected score for average children also increases. A child's age is a main factor for interpreting ICS scores.
