Purpose: This study aimed to analyse the relationship between the use of digital devices, family function, and language development in preschool children.

Methods: This cross-sectional, descriptive-correlational study included a sample of 93 parent-child dyads. The children were of an average age of 57.01 ± 9.95 months, and the majority were female. The data collection instruments included a questionnaire on the use of digital devices, the Portuguese version of the Family Flexibility and Cohesion Evaluation Scale - Version IV (FACES-IV), and a Preschool Language Test (TL-ALPE).

Results: The findings showed a greater tendency of children to use smartphones, tablets, and television for 0-3 hours daily. The analysis of the responses on the FACES-IV and TL-ALPE instruments showed that most of the participating families were of the balanced type and that most children had normal language development. Statistically significant relationships were found between the FACES-IV subscales and TL-ALPE subtests, FACES-IV subscales and the use of digital devices, and the use of digital devices and TL-ALPE subtests. Notably, children in more balanced family functioning scored higher on TL-ALPE tests, and the time spent using digital devices may compromise language development.

Conclusion: This study highlights the impact of digital device use and the role of family functioning on children's language development, suggesting that moderate digital device use and balanced family functioning are facilitating factors for good language development.

Purpose: To analyze hyperbilirubinemia as an indicator for the definition of risk protocol in newborn hearing screening (NHS) and in auditory monitoring in full-term and preterm neonates.

Methods: This is an observational, cross-sectional and retrospective study. A total of 554 children born in a public maternity hospital were included and divided into two groups: (G1) with 373 full-terms neonates; (G2) with 181 preterm neonates. Data were collected from the participant's medical records to obtain information regarding the result of the NHS, performed by recording the automated auditory brainstem response (AABR), birth conditions, clinical characteristics, interventions performed, and results of the first test of total bilirubin (TB) and indirect bilirubin (IB) as well as the peak of TB and IB. A descriptive statistical analysis of the results was performed, and the level of significance adopted was 5%.

Results: On the NHS test, quotes of retest referral rates were smaller in G1 when compared to G2. There was no significant difference between the groups regarding type of delivery, gender, presence of Rh and ABO incompatibility, G6PD enzyme deficiency, and performance of phototherapy. TB and IB levels at the first exam and at peak time did not differ between neonates with "pass" and "fail" results on the NHS test in both groups.

Conclusion: Bilirubin levels in the neonatal period below the recommended values for indication of exchange transfusion are not directly related to the "fail" result on the NHS tests in term and preterm neonates.

Purpose: The inter-aural time difference (ITD) and inter-aural level difference (ILD) are important acoustic cues for horizontal localization and spatial release from masking. These cues are encoded based on inter-aural comparisons of tonotopically matched binaural inputs. Therefore, binaural coherence or the interaural spectro-temporal similarity is a pre-requisite for encoding ITD and ILD. The modulation depth of envelope is an important envelope characteristic that helps in encoding the envelope-ITD. However, inter-aural difference in modulation depth can result in reduced binaural coherence and poor representation of binaural cues as in the case with reverberation, noise and compression in cochlear implants and hearing aids. This study investigated the effect of inter-aural modulation depth difference on the ITD thresholds for an amplitude-modulated noise in normal hearing young adults.

Methods: An amplitude modulated high pass filtered noise with varying modulation depth differences was presented sequentially through headphones. In one ear, the modulation depth was retained at 90% and in the other ear it varied from 90% to 50%. The ITD thresholds for modulation frequencies of 8 Hz and 16 Hz were estimated as a function of the inter-aural modulation depth difference.

Results: The Friedman test findings revealed a statistically significant increase in the ITD threshold with an increase in the inter-aural modulation depth difference for 8 Hz and 16 Hz.

Conclusion: The results indicate that the inter-aural differences in the modulation depth negatively impact ITD perception for an amplitude-modulated high pass filtered noise.

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.

Purpose: Create a checklist of the International Classification of Functioning, Disability and Health (ICF) based on relevant categories for the development of speech and language, according to the perception of parents and speech therapists.

Methods: Pilot application and research were carried out. 100 parents of preschool children with typical language/cognition development and 57 language specialist speech therapists participated in the survey. A questionnaire was created with 199 ICF categories of body function components, activities and participation, and environmental factors. Each category was scored as: indispensable (2); important (1) or unimportant (0). Statistical analysis was performed (descriptive, sum, cluster/K-means and Mann-Whitney method).

Results: With the sum of the points (essential, important and unimportant) and the number of responses essential, the most relevant categories were identified for each group of respondents, as well as the set of categories in common (72 considered to have the greatest influence). The common list to the groups included the three components: body functions (30 categories/40% of the total), activities and participation (35/49.29%) and environmental factors (seven/13.20%). From the selected categories, 58.33% presented statistically significant results between the groups, regarding the relevance given.

Conclusions: The categories were considered with different scores between the groups: those of body functions were more scored by speech therapists, while those of environmental factors by parents. Thus, it was possible to create a checklist from the identification of the most relevant categories for the development of speech and language, in preschool age, contemplating the components of body functions, activities and participation and environmental factors.
