The development of a vocabulary for PEEPS-SE-profiles of early expressive phonological skills for Swedish

Content validity of the Profiles of Early Expressive Phonological Skills-Brazilian Portuguese (PEEPS-BP) - Expanded List

PURPOSE

To carry out the cross-cultural adaptation of the Instrument Profiles of Early Expressive Phonological Skills- Brazilian Portuguese (PEEPS-BP) - Expanded list, performing content validation.

METHODS

Cross-cultural, quantitative and cross- sectional adaptation study, considering psychometric criteria. A study was carried out on the list of 423 words from the Communicative Development Inventory - MacArthur - Words and Sentences, adapted to Brazilian Portuguese. The method was divided into four steps. The list was judged by expert judges (JE) and non-specialist judges (JNE), considering as a criterion the familiarity of the word for a child aged between 24 and 36 months, and the representativeness of the word with toy/object, contemplating Steps 1 and 2. The child judges analyzed, in a data collection situation, the familiarity and representativeness of the stimulus-words, presented in Step 3. Afterwards, the pilot study - Step 4, was carried out with the selected stimulus-words. In the statistical analysis by expert and non-specialist judges, the Fleiss' Kappa and Gwet Concordance index was used. In the analysis of the responses of the child judges and in the Pilot Study, the analysis was made in relation to the type of response of the child, specifically scoring the spontaneous naming of the toy/object, scoring qualitatively.

RESULTS

The result of Steps 1 and 2, and the agreement of the statistical tests for the Familiarity and Representativeness criteria was 45.7% for JE and 76.4% for JNE, and a result of 100% for the agreement of Representativeness. A total of 122 words were analyzed, resulting from previously established criteria, totaling 34 words (exclusion of one word by the researchers), totaling 33 stimulus-words. In Stage 3, of the 33 stimulus-words applied, nine presented spontaneous naming scores below expectations, being retested for Step 4, the Pilot Study. The result of the Pilot Study showed that of the nine retested stimulus-words, four of them still had a score below, being excluded from the study. Therefore, with the application of the Pilot Study, the expanded list of PEEPS-BP resulted in 29 words.

CONCLUSION

The PEEPS-BP - Expanded List showed satisfactory evidence of content validity for the cross-cultural adaptation of the test.

Expressive vocabulary development in children with moderate hearing loss - the impact of auditory variables and early consonant production

In this study, the early expressive vocabulary development was investigated in a group of children with moderate hearing loss (HL). Size and development of expressive vocabulary from 18 30 months were analyzed and compared to a group of children with normal hearing (NH). For the children with HL, the impact of auditory variables on number of words were examined. The relationship of early consonant production to number of words produced of both groups were examined and the phonological complexity of reported words was compared between the groups. The results showed that children with HL (n = 8) produced a similar number of words as the NH (n = 8) at 18 months, but fewer at 24 and 30 months. Hours of HA use showed significant correlations to number of words. The number of different true consonants at 18 months for the whole group showed a significant relationship to number of words produced at 24 months. No significant differences were found between children with HL and NH children regarding phonological complexity of reported words. The findings indicate that the children born with moderate HL who were fitted with hearing aids (HAs) before 6 months of age are at risk in their development of expressive vocabulary. Full-time use of HAs and monitoring of early consonant use should be encouraged in the early intervention of this target group.

Introducing WCM-SE: The word complexity measure phonetically justified and adapted to Swedish

This paper presents the Word Complexity Measure for Swedish (WCM-SE), an adaptation of the original WCM developed for English by Stoel-Gammon. These measures are used to calculate the phonological complexity of words or vocalizations, based on a number of phonological complexity parameters. Each production receives a complexity score based on how many of the parameters are present in the production. Using phonological complexity scores to measure expressive phonology is suitable for assessing very young children, children with early phonology and children with phonological deficits. It is useful for both relational and independent analyses and enables comparisons between children and across development. The original WCM uses eight phonological complexity parameters in three domains: word patterns, syllable structures and sound classes. The parameters selected are phonological characteristics that are acquired late in development among English-speaking children. In the WCM-SE, complexity parameters in the domain sound classes were modified or added according to Swedish or universal patterns of phonology development. The parameters' complexity is accounted for in terms of language-general phonetic characteristics.
