Results of the lexical development in pediatric cochlear implantation using the FRAKIS
18 April 2018 (online)
The Questionnaire for the early speech development (FRAKIS) offers an insight into the lexical development of German speaking children in an age between 18 and 30 months (Szagun 2009).
Materials and Methods:
The part “Lexicon” of the FRAKIS consists of a checklist of 600 words. Parents are asked to check the words that are produced by their child (added to a total score TS). The retrospective cross-sectional study analyzed the datasets of 89 children. Statistical analyses were performed using measures of central tendency, correlations as well as non-parametric between-groups comparisons.
24 children were excluded. The mean age of the 65 included children was 25 months (19 – 30), the mean duration after the initial implantation (“hearing age”) 13 months (1 – 23), and the mean TS was 109 words (0 – 534). TS and hearing age correlated positively (Pearson r = 0.376, p = 0.002) whereas TS and age at implantation correlated negatively (Pearson r =-.275, p = 0.026). There was no significant difference in TS between boys and girls (p = 0.713). In 47 children (72%) the TS lied in the lower sector of the normal values, compared to normal hearing children.
The results indicate that an early implantation affects the lexical development positively. A comparison between the examined sample and normal hearing children suggests that children with cochlear implants have a disadvantage in their lexical development.
