RESUMO
BACKGROUND: There is growing evidence that COVID-19 brought changes that immediately affected early language development. Little is known for how long these COVID-19 related changes shaped development. The current study systematically and longitudinally addressed this issue, following up children's language development throughout the first 2.5 years. METHOD: The present study follows up on the sample from Frota et al. (2022), which demonstrated that 7-9-month-old infants born and raised during the pandemic do not segment words unlike pre-pandemic peers. Four studies were conducted: (1) word segmentation task at 12 months of age (Npandemic = 15); (2) word learning task at 20 months of age (Npandemic = 20); (3) language and communication development up to 30 months of age, via CDI and CSBS parental reports (Npandemic ranged 25-74); (4) overall development at 30 months of age using the Griffiths Developmental Scales (Npandemic = 16). RESULTS: The pandemic sample consistently underperformed in all four studies in comparison to pre-pandemic data. There was no evidence of developed word segmentation abilities at 12 months of age, and no successful word learning at 20 months of age. Lexical development between 12 and 24 months of age was lower than in the pre-pandemic sample, while social communication did not seem to be affected. At 30 months of age, the pandemic sample showed lower scores and lower mental age on the Language and Communication Griffiths' subscale, in comparison to the pre-pandemic data. CONCLUSIONS: Infants born and raised during the pandemic have a poorer language development, that persists at least until 30 months of age.

PURPOSE: Cross-language studies suggest more similarities than differences in how dysarthria affects the speech of people with Parkinson's disease (PwPD) who speak different languages. In this study, we aimed to identify the relative contribution of acoustic variables to distinguish PwPD from controls who spoke varieties of two Romance languages, French and Portuguese. METHOD: This bi-national, cross-sectional, and case-controlled study included 129 PwPD and 124 healthy controls who spoke French or Portuguese. All participants underwent the same clinical examinations, voice/speech recordings, and self-assessment questionnaires. PwPD were evaluated off and on optimal medication. Inferential analyses included Disease (controls vs. PwPD) and Language (French vs. Portuguese) as factors, and random decision forest algorithms identified relevant acoustic variables able to distinguish participants: (a) by language (French vs. Portuguese) and (b) by clinical status (PwPD on and off medication vs. controls). RESULTS: French-speaking and Portuguese-speaking individuals were distinguished from each other with over 90% accuracy by five acoustic variables (the mean fundamental frequency and the shimmer of the sustained vowel /a/ production, the oral diadochokinesis performance index, the relative sound level pressure and the relative sound pressure level standard deviation of the text reading). A distinct set of parameters discriminated between controls and PwPD: for men, maximum phonation time and the oral diadochokinesis speech proportion were the most significant variables; for women, variables calculated from the oral diadochokinesis were the most discriminative. CONCLUSIONS: Acoustic variables related to phonation and voice quality distinguished between speakers of the two languages. Variables related to pneumophonic coordination and articulation rate were the more effective in distinguishing PwPD from controls. Thus, our research findings support that respiration and diadochokinesis tasks appear to be the most appropriate to pinpoint signs of dysarthria, which are largely homogeneous and language-universal. In contrast, identifying language-specific variables with the speech tasks and acoustic variables studied was less conclusive.
RESUMO
BACKGROUND: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social communication skills in European Portuguese (EP)-learning children, which is critical for screening, monitoring and enrolment in appropriate early intervention services. AIMS: (1) To adapt and validate the EP version of the Communication and Symbolic Behaviour Scales Developmental Profile™ (CSBS DP™) Infant-Toddler Checklist, a parental report for the screening of early language and social communication skills. (2) To conduct a cross-cultural comparison between the EP adaptation and the original US version. METHODS & PROCEDURES: A total of 611 EP-learning children (ages 6-24 months) were assessed on the CSBS DP Infant-Toddler Checklist. Normative data, psychometric characteristics (i.e., internal consistency and test-retest reliability), and cross-cultural comparison between the EP and the original version were explored. OUTCOMES & RESULTS: Internal consistency ranged from good to excellent and the test-retest reliability was excellent. The performance of the EP and US samples matched on almost all scores. However, EP children performed significantly better than their American peers in the Social compositive at 22 months and in the Symbolic composite at 20 months. No further differences were found. CONCLUSIONS & IMPLICATIONS: These findings showed that the EP CSBS DP Infant-Toddler Checklist seems to be a reliable screening tool of communicative and symbolic behaviours for EP-learning children, which can be particularly relevant for decision-making in clinical practice. WHAT THIS PAPER ADDS: What is already known on the subject Early communication skills are known to be related to later language outcomes. Thus, screening tools for the early identification of children at risk for language and communication impairments, which may lead to monitoring and early intervention, have the potential to promote better outcomes. However, to the best of our knowledge, no screening tool is available for the assessment of early communication abilities in EP-learning children. What this paper adds to existing knowledge This study adapted and validated the EP CSBS DP Infant-Toddler Checklist, the first published parental report checklist for the assessment of early communication skills in EP. It described the psychometric characteristics of the adapted checklist, summarized the newly available normative data for EP-learning infants and toddlers, and compared the performance of EP-learning children with the original standardization sample reported for American English. The results demonstrated that this tool is a reliable instrument for the early screening of language, communicative and symbolic behaviours for EP-learning children between 6 and 24 months of age. What are the potential or actual clinical implications of this work? Given that early screening is crucial to promote prevention, early diagnosis and intervention, the availability of this tool is particularly relevant for children monitoring and their enrolment in appropriate early intervention services, helping decision-making in clinical practice, in line with current guidelines regarding early monitoring and intervention to promote and support better outcomes. Thus, the tool and related normative data will be useful for paediatricians, family doctors, primary healthcare providers, developmental psychologists and speech-language therapists, among other professionals in the healthcare and educational fields, concerned with speech, language, and communication development and impairments.

This study describes the development and validation of Proso-Quest, a parental report of toddlers' prosodic skills that aims to assess early prosodic development in European Portuguese. The development and validation of Proso-Quest proceeded in three phases. Phase 1 was undertaken (a) to establish the structure of the parental report and select the items considering previous work, (b) to collect input from experts on prosodic development, and (c) to revise the report after a pilot study. Phase 2 examined internal consistency, reliability, test-retest reliability, and correlations between Proso-Quest and a valid measure of vocabulary development. Finally, Phase 3 evaluated the discriminant validity of this report in a clinical sample that frequently presents prosodic impairments. The psychometric properties of Proso-Quest indicated an excellent internal consistency, high test-retest reliability, significant correlations with a valid measure of vocabulary development, and sensitivity to identify prosodic delays. This parental report showed evidence of reliability and validity in describing early prosodic development and impairment, and it may be a useful tool in research and educational assessments, as well as in clinical-based assessments.
RESUMO
Infants have been shown to rely both on auditory and visual cues when processing speech. We investigated the impact of COVID-related changes, in particular of face masks, in early word segmentation abilities. Following up on our previous study demonstrating that, by 4 months, infants already segmented targets presented auditorily at utterance-edge position, and, using the same visual familiarization paradigm, 7-9-month-old infants performed an auditory and an audiovisual word segmentation experiment in two conditions: without and with an FFP2 face mask. Analysis of acoustic and visual cues showed changes in face-masked speech affecting the amount, weight, and location of cues. Utterance-edge position displayed more salient cues than utterance-medial position, but the cues were attenuated in face-masked speech. Results revealed no evidence for segmentation, not even at edge position, regardless of mask condition and auditory or visual speech presentation. However, in the audiovisual experiment, infants attended more to the screen during the test trials when familiarized with without mask speech. Also, the infants attended more to the mouth and less to the eyes in without mask than with mask. In addition, evidence for an advantage of the utterance-edge position in emerging segmentation abilities was found. Thus, audiovisual information provided some support to developing word segmentation. We compared 7-9-monthers segmentation ability observed in the Butler and Frota pre-COVID study with the current auditory without mask data. Mean looking time for edge was significantly higher than unfamiliar in the pre-COVID study only. Measures of cognitive and language development obtained with the CSBS scales showed that the infants of the current study scored significantly lower than the same-age infants from the CSBS (pre-COVID) normative data. Our results suggest an overall effect of the pandemic on early segmentation abilities and language development, calling for longitudinal studies to determine how development proceeds.
RESUMO
The phonology of prosody has received little attention in studies of motor speech disorders. The present study investigates the phonology of intonation (nuclear contours) and speech chunking (prosodic phrasing) in Parkinson's disease (PD) as a function of medication intake and duration of the disease. Following methods of the prosodic and intonational phonology frameworks, we examined the ability of 30 PD patients to use intonation categories and prosodic phrasing structures in ways similar to 20 healthy controls to convey similar meanings. Speech data from PD patients were collected before and after a dopaminomimetic drug intake and were phonologically analyzed in relation to nuclear contours and intonational phrasing. Besides medication, disease duration and the presence of motor fluctuations were also factors included in the analyses. Overall, PD patients showed a decreased ability to use nuclear contours and prosodic phrasing. Medication improved intonation regardless of disease duration but did not help with dysprosodic phrasing. In turn, disease duration and motor fluctuations affected phrasing patterns but had no impact on intonation. Our study demonstrated that the phonology of prosody is impaired in PD, and prosodic categories and structures may be differently affected, with implications for the understanding of PD neurophysiology and therapy.
RESUMO
The ability to perceive lexical stress patterns has been shown to develop in language-specific ways. However, previous studies have examined this ability in languages that are either clearly stress-based (favoring the development of a preference for trochaic stress, like English and German) or syllable-based (favoring the development of no stress preferences, like French, Spanish, and Catalan) and/or where the frequency distributions of stress patterns provide clear data for a predominant pattern (like English and Hebrew). European Portuguese (EP) is a different type of language, which presents conflicting sets of cues related to rhythm, frequency, and stress correlates that challenge existing accounts of early stress perception. Using an anticipatory eye movement (AEM) paradigm implemented with eye-tracking, EP-learning infants at 5-6 months demonstrated sensitivity to the trochaic/iambic stress contrast, with evidence of asymmetrical perception or preference for iambic stress. These results are not predicted by the rhythmic account of developing stress perception, and suggest that the language-particular phonological patterns impacting the frequency of trochaic and iambic stress, beyond lexical words with two or more syllables, together with the prosodic correlates of stress, drive the early acquisition of lexical stress. Our findings provide the first evidence of sensitivity to stress patterns in the presence of segmental variability by 5-6 months, and highlight the importance of testing developing stress perception in languages with diverse combinations of rhythmic, phonological, and phonetic properties.
RESUMO
ABSTRACT BACKGROUND: Package leaflets of medicines need to be intelligible, but tools for their evaluation are scarce. OBJECTIVE: To validate a new tool for assessing subjects' satisfaction with medicine package leaflets (LiS-RPL). DESIGN AND SETTING: Cross-sectional descriptive study conducted in two regions of Portugal (Lisbon and Centre). METHODS: 503 participants (53.1% male) were selected according to convenience and homogenously distributed into three groups: 1 to 6; 7 to 12; and > 12 years of schooling. LiS-RPL was developed based on international regulation guidelines and was initially composed of 14 items. Twelve package leaflets were tested. Dimensionality calculations included: exploratory factor analysis and minimum rank factor analysis; Kaiser-Meyer-Olkin index and Bartlett's sphericity test to assess matrix adequacy for exploratory factor analysis; exploratory bifactor analysis with Schmid-Leiman solution to detect possible existence of a broad second-order factor; and Bentler's Simplicity Index and Loading Simplicity Index to assess factor simplicity. Diverse coefficients were calculated to assess reliability. RESULTS: Minimum rank factor analysis detected a two-factor or single-factor structure. Exploratory factor analysis with 12 items showed a two-factor structure, explaining 69.11% of the variance. These items were strongly correlated with each other (r = 0.80). Schmid-Leiman: all items seemed to represent the general factor (loadings above 0.50), which was 76.4% of the extracted variance. Simplicity indices were good (percentile 99): Bentler's Simplicity Index of 0.99 and Loading Simplicity Index of 0.48. Internal consistency indexes indicated good reliability. LiS-RPL was shown to be homogenous. CONCLUSION: LiS-RPL is a validated tool for evaluating subjects' satisfaction with medicine package leaflets.

Two outstanding questions in spoken-language comprehension concern (1) the interplay of phonological grammar (legal vs. illegal sound sequences), phonotactic frequency (high- vs. low-frequency sound sequences) and lexicality (words vs. other sound sequences) in a meaningful context, and (2) how the properties of phonological sequences determine their inclusion or exclusion from lexical-semantic processing. In the present study, we used a picture-sound priming paradigm to examine the ERP responses of adult listeners to grammatically illegal sound sequences, to grammatically legal sound sequences (pseudowords) with low- vs. high-frequency, and to real words that were either congruent or incongruent to the picture context. Results showed less negative N1-P2 responses for illegal sequences and low-frequency pseudowords (with differences in topography), but not high-frequency ones. Low-frequency pseudowords also showed an increased P3 component. However, just like illegal sequences, neither low- nor high-frequency pseudowords differed from congruent words in the N400. Thus, phonotactic frequency had an impact before, but not during lexical-semantic processing. Our results also suggest that phonological grammar, phonotactic frequency and lexicality may follow each other in this order during word processing.

The goal of this study was to adapt, improve and validate a short, self-administered health literacy assessment tool for European Portuguese-speaking adults. Health literacy tools are of great importance to health authorities and professionals, as low or inadequate health literacy, that is, a limited capacity to handle health-related information, is associated with higher morbidity and mortality. The 18-item Short Assessment of Health Literacy for Brazilian Portuguese-speaking adults (SAHLPA-18) was adapted into European Portuguese. The European Portuguese tool (SAHLPA-23) includes five additional items. The SAHLPA-23 was tested in a convenience sample of 503 participants from two Portuguese regions. Socio-demographic data, literacy and cognitive indicators were collected. Participants also completed a questionnaire on comprehension of written health materials. Construct validity was assessed through correlations between SAHLPA-23 scores and education, literacy, and cognitive variables and score on the comprehension questionnaire. The psychometric properties of the new tool were compared with those of the SAHLPA-18. The mean SAHLPA-18 and SAHLPA-23 scores were 13.9 (77.2%; SD=2.9) and 18.3 (79.6%; SD=3.8), respectively. Both tools showed adequate reliability (Cronbach's α>0.7). SAHLPA-23 was more highly correlated with all study variables than SAHLPA-18. Although both instruments displayed acceptable discriminative power, SAHLPA-23 had better accuracy than SAHLPA-18 (DeLong's method: ΔAUC=0.09, Z=3.36; P<0.001). The SAHLPA-23 is an independent, feasible and innovative tool for estimation of health literacy in the Portuguese adult population.
RESUMO
European Portuguese (EP) is a language with variable stress, and the main cues for stress are duration and vowel reduction. A previous behavioral study has reported a stress "deafness" effect in EP when vowel quality cues are unavailable. The present study recorded both event-related potentials (ERPs) and behavioral data to examine the stress processing by native EP speakers in the absence of the vowel quality cues. Our behavioral result was consistent with previous research, showing that when vowel reduction is absent EP speakers demonstrated a stress "deafness" effect similar to that found in speakers of languages with fixed stress or without any lexical stress marking. In the ERP task, both the trochaic and iambic conditions yielded mismatch negativity (MMN) and late negativity, suggesting that EP speakers are able to discriminate the two stress patterns without vowel reduction at the pre-attentive stage. Moreover, the ERP and behavioral data revealed compatible results regarding the pattern of stress bias in EP. In the EPR task, the MMN and late negativity components were more negative and span over a larger temporal window in the iambic condition than in the trochaic condition, indicating a higher sensitivity for the iambic stress pattern. In the behavioral task, EP speakers responded more accurately and more quickly to the iambic stress. These results match recent developmental findings in the acquisition of stress, but speak against the dominant view in EP phonological literature which assumes penultimate stress to be the regular stress pattern. In addition, both the ERP and the behavioral data showed that EP speakers' stress processing was influenced by their working memory (WM) capacity. The participants with high WM capacity outperformed the participants with limited WM capacity in the iambic condition. In sum, our results broaden the current knowledge on stress processing by EP speakers at both the pre-attentive and attentive levels.
RESUMO
OBJECTIVES: Focusing on the shape of brand names of medicines in the Portuguese market, the aims of this study were: to evaluate the number of words, syllables and letters, to identify the combinations of letters that are not found in Portuguese words and to characterize the use of capital letters in these names. METHODS: A descriptive study was conducted using 474 randomized brand names of medicines, approximately 25% of all over-the-counter and prescribed medicines available in Portugal. The number of words, syllables and letters was automatically determined with a dedicated software. The combinations of letters that are not found in Portuguese and the use of capital letters were quantified through visual inspection. KEY FINDINGS: The 474 names were formed by 615 words. 74.5% of the words comprised three or less syllables, the most common number of syllables in the Portuguese words (91%). As recommended, 81% (n = 385) names were formed by just one word, 59.2% (n = 281) of the names were composed of 5-8 letters, and 83.1% (n = 394) presented the first letter in capitals or all letters in upper case. Contrary to recommendations, 22% of the names comprised combinations of letters that are not commonly found in Portuguese words. CONCLUSIONS: Given the current readability requirements, some of the Portuguese brand names of medicines should be reduced in length, adapted to the native language or capitalized. Equivalent studies are recommended in other European countries, because many brands of medicines are internationally marketed, while their development and approval should be beyond general marketing rules.

INTRODUCTION: Individuals with Parkinson's disease (PD) have to deal with several aspects of voice and speech decline and thus alteration of communication ability during the course of the disease. Among these communication impairments, 3 major challenges include: (1) dysarthria, consisting of orofacial motor dysfunction and dysprosody, which is linked to the neurodegenerative processes; (2) effects of the pharmacological treatment, which vary according to the disease stage; and (3) particular speech modifications that may be language-specific, that is, dependent on the language spoken by the patients. The main objective of the FraLusoPark project is to provide a thorough evaluation of changes in PD speech as a result of pharmacological treatment and disease duration in 2 different languages (French vs European Portuguese). METHODS AND ANALYSIS: Individuals with PD are enrolled in the study in France (N=60) and Portugal (N=60). Their global motor disability and orofacial motor functions is assessed with specific clinical rating scales, without (OFF) and with (ON) pharmacological treatment. 2 groups of 60 healthy age-matched volunteers provide the reference for between-group comparisons. Along with the clinical examinations, several speech tasks are recorded to obtain acoustic and perceptual measures. Patient-reported outcome measures are used to assess the psychosocial impact of dysarthria on quality of life. ETHICS AND DISSEMINATION: The study has been approved by the local responsible committees on human experimentation and is conducted in accordance with the ethical standards. A valuable large-scale database of speech recordings and metadata from patients with PD in France and Portugal will be constructed. Results will be disseminated in several articles in peer-reviewed journals and in conference presentations. Recommendations on how to assess speech and voice disorders in individuals with PD to monitor the progression and management of symptoms will be provided. TRIAL REGISTRATION NUMBER: NCT02753192, Pre-results.

Background Package inserts (PIs) should promote the safe and effective use of medicines. The comprehension of PIs is related to socio-demographic features, such as education. Objectives To evaluate the participants' comprehension of a sample of PIs and to build an explanatory model of subjects' understanding of the content of these documents. Setting The data were collected from municipalities, city halls, firefighters, the military, schools and charities from two Portuguese regions. Methods Cross-sectional descriptive survey: 503 participants, homogeneously distributed by education and gender. The self-administered tool comprised questions on socio-demographic data, literacy tasks and comprehension evaluation of 12 purposively selected PIs. A logistic regression analysis was used. Main outcome measures Scores of numeracy tasks and comprehension. Results The average comprehension score for the PIs was 63 % (±32 %), with 48 % (n = 239) of the participants scoring <75 %. The most important predictors in explaining a comprehension score ≥75 % were having >12 years of education and correctly performing a numeracy task [respectively, OR 49.6 (CI 95 %: 22.8-108) and OR 2.48 (CI 95 %: 1.5-4.2)]. Conclusion An explanatory model of subjects' knowledge about the content of the tested PIs was built. Given that a high level of education and literacy were found to be the most relevant predictors for acceptable comprehension rates, PIs should be clearly written to assure that they are understood by all potential users, including the less educated. The evaluated PIs may thus need to be simplified.

BACKGROUND: The graphical content of the Medicines Package Inserts (MPIs), such as illustrations and typographic features should be legible and appropriate, as required by international pharmaceutical regulations. OBJECTIVES: To study: (1) the frequency and type of MPIs' key graphic elements, (2) their compliance with regulations and (3) how educated people understand them. METHODS: Descriptive study: characterisation of the graphical content of 651 MPIs. Usability study: illustrations and tables (purposively selected) were evaluated with questionnaires in three groups of humanities undergraduates (illustrations only, illustrations plus text and text only). RESULTS: Descriptive study: illustrations and tables were respectively identified in 6.3% and 11.8% of the MPIs. The illustrations were mainly related to how to take/use the medicine. Non-recommended graphical representations were found (e.g. italic or underline). Usability test: legibility issues were identified, especially for the group of isolated illustrations. DISCUSSION & CONCLUSIONS: The scarce use of illustrations and tables possibly affected the legibility of the MPIs. Compulsory legibility tests are needed to guarantee the MPIs' proper use, thus contributing to a safe use of medicines. Overall, this study highlighted the need to carefully revise/assess the MPIs' design and probably increase health information experts' awareness on this issue.

Abstract Among other regulatory requirements, medicine brands should be composed of single names without abbreviations to prevent errors in prescription of medication. The purposes of the study were to investigate the compliance of a sam ple of Portuguese medicine brand names with Portuguese pharmaceutical regulations. This includes identifying their basic linguistic characteristics and comparing these features and their frequency of occurrence with benchmark values of the colloquial or informal language. A sample of 474 brand names was selected. Names were analyzed using manual (visual analyses) and computer methods (FreP - Frequency Patterns of Phonological Objects in Portuguese and MS word). A significant number of names (61.3%) failed to comply with the Portuguese phonologic system (related to the sound of words) and/or the spelling system (related to the written form of words) contained more than one word, comprised a high proportion of infrequent syllable types or stress patterns and included abbreviations. The results suggest that some of the brand names of Portuguese medication should be reevaluated, and that regulation on this issue should be enforced and updated, taking into consideration specific linguistic and spelling codes.
Resumo Entre outros requisitos regulatórios, o nome dos medicamentos de marca deve ser composto por um único nome e não integrar abreviaturas para evitar erros de medicação. Os objetivos do estudo foram: investigar a adequação de um grupo de nomes de medicamentos de marca portugueses à regulação farmacêutica do mesmo País; identificar as suas características linguísticas básicas e comparar essas características e a sua frequência com valores de referência da língua corrente ou informal. Foi selecionada uma amostra de 474 nomes. Os nomes foram analisados com recurso a métodos manuais (análise visual) e automáticos (FreP - Frequency Patterns of Phonological Objects in Portuguese e o MS word). Um número significativo de nomes (61,3%) não estava em conformidade com o sistema fonológico (relacionado com a forma sonora das palavras) e ortográfico do Português (relacionado com a forma de escrita das palavras), tinha mais de uma palavra, continha uma alta proporção padrões silábicos e acentuais raros, e incluía abreviaturas. Os resultados sugerem que alguns dos nomes das marcas medicamentos portugueses devem ser reavaliadas e os aspetos regulatórios atualizados, tendo em consideração as características específicas do sistema linguístico e ortográfico português.
