Miriam Hansen e as contribuições da Escola de Frankfurt para a teoria do cinema

Historiadora do cinema, Miriam Hansen examinou e sistematizou as contribuições de Siegfried Kracauer, Walter Benjamin e Theodor Adorno para a teorização do cinema. Nesta pesquisa bibliográfica, buscamos sintetizar e apresentar aos leitores de língua portuguesa o desenvolvimento de sua investigação sobre o tema. Mostramos como Hansen foi capaz de identificar as principais diferenças entre os teóricos frankfurtianos, bem como evidenciar que eles, em comum, pensaram este fenômeno cultural contemporâneo em relação às condições sociais e econômicas de produção. Em suas reflexões, o cinema aparece como expressão da sociedade urbano-industrial, como um elemento sintomático da cultura de massa.

Validation of the Brazilian Portuguese Version of the 24-Item Early-Onset Scoliosis Questionnaire.

Study Design:Multicenter prospective study.Objectives:To validate the Early-Onset Scoliosis 24 Questionnaire (EOSQ-24) questionnaire for the Brazilian Portuguese language, a widely used tool for assessing the impact of different treatments and interventions in EOS patients.Methods:The EOSQ-24 questionnaire was cross-culturally adapted following guidelines already published. After language adjustments by a group of experts, the final version of the Brazilian Portuguese EOSQ-24 was applied to a group of 76 patients (35 male and 41 female). Internal consistency was evaluated using the Cronbach α coefficient and item-total correlations. Continuous variables were recorded as median values and interquartile ranges and categorical variables as percentages.Results:In the study group, 76 patients were evaluated. The total EOSQ-24 Cronbach α coefficient was 0.883, indicating excellent reliability. The internal consistency of EOSQ-24 was assessed in 3 domains: patient quality of Life, parental burden, and satisfaction (Cronbach α: 0.816-0.934). The range across all subdomains was 0.473 to 0.934. Floor effects for the 24 items were between 1.3% and 43.4% and ceiling effects, between 3.9% and 42.1%.Conclusions:The Brazilian Portuguese adaptation of the EOSQ-24 shows excellent reliability and can be a valid tool for psychometric assessment of children with EOS.

Validation and cultural translation for the Brazilian Portuguese version of the Questionnaire for Urinary Incontinence Diagnosis.

Short questionnaires are important for validating the clinical diagnosis of urinary incontinence (UI). We sought to validate and culturally translate the Questionnaire for Urinary Incontinence Diagnosis (QUID) for the Brazilian Portuguese language. A cross-sectional study with 457 women (330 with urinary incontinence and 127 controls) was performed in a Southeastern Brazilian outpatient clinic. Patients answered a pilot-tested, notarized, six-item questionnaire (QUID) for internal consistency as well as a control questionnaire (ICIQ-SF and ICIQ-OAB) for construct validity. In both groups, floor and ceiling effects were calculated. Within UI women, test-retest (n=41) and responsiveness to conservative treatment (n=74) were also analyzed. Internal consistency (Cronbach's alpha) from the QUID was adequate between the UI (0.845-0.850) and control (0.724-0.775) groups. Mean QUID scores were statistically different between UI and control groups (p<0.05). No ceiling or floor effects were observed in incontinent patients. Test-retest reliability after 4 weeks (intraclass correlation coefficient [ICC]: 0.780-0.814) and responsiveness (0.867-0.889) were also adequate within UI women. Construct validity was adequate at all correlations between QUID and ICIQ-SF and ICIQ-OAB (r: 0.19-0.58; p<0.05). Responsiveness was demonstrated by a statistically significant difference in questions/subscale sores after physical therapy. The QUID presented adequate cultural translation, reliability, and good responsiveness to treatment in the Brazilian Portuguese language.

Assessment on the measurement properties of the Brazilian Portuguese language version of the International Consultation on Incontinence Questionnaire Female Sexual Matters Associated with Lower Urinary Tract Symptoms Module (ICIQ-FLUTSsex)

Abstract Objectives: to assess internal consistency and reliability in providing a Portuguese version of the International Consultation on Incontinence Questionnaire Female Sexual Matters Associated with Lower Urinary Tract Symptoms Module (ICIQ-FLUTSsex). Methods: a validation study was conducted by applying questionnaires for 56 women over 18 years old with active sexual life and presenting urinary incontinence, excluding those who had urinary infection in the past 6 months. Three questionnaires were used, one for personal identification; the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and the ICIQ-FLUTSsex. SPSS software was used for data analysis. Cronbach's alpha was used to verify reliability of the items on the questionnaires and Kappa coefficient was used to assess the agreement between the questionnaires applied in the test-retest. Results: the median age was 49.1 years old, mostly were mixed colored skin and married, with a high prevalence of mixed urinary incontinence. Cronbach's alpha score was 0.80, which was considered good. Kappa value was moderate, ranging from 0.36 to 0.76. Conclusion: internal consistency was considered good and reliability moderate. The Portuguese version of ICIQ-FLUTSsex was proven to be valid to use on women with urinary incontinence, contributing for clinical practice, as it provides as a quick tool for research on sexual dysfunction.

Pelvic floor disorders in women with premature ovarian insufficiency: a cross-sectional study.

This study aimed to investigate the prevalence of self-reported main pelvic floor disorders (PFD) (urinary incontinence [UI], pelvic organ prolapse [POP], and fecal incontinence [FI]) and its associated factors in women with premature ovarian insufficiency (POI) and a control group. This was a cross-sectional study wherein two groups were interviewed from August, 2017 to November, 2018-women with POI (n = 150) and a control group matched for age and body weight (n = 150). Sociodemographic variables and two questionnaires validated in Brazilian Portuguese language for PFD (Kings Health Questionnaire [KHQ] and Pelvic Floor Distress Inventory-20 [PFDI-20]) were used. Laycock's power, endurance, repetitions, fast contractions, every contraction timed (PERFECT) scale for pelvic floor muscle assessment was used in both groups. The prevalence of self-reported UI was 27.33% and 37.33% for POI and control groups (P > 0.05), respectively. There was no perceived difference regarding the prevalence of POP (9.33% POI group vs 8% control group; P = 0.682) and FI (8% POI vs 4% control group; P = 0.145). The P (power) (P = 0.46), E (endurance) (P = 0.91), R (repetitions) (P = 0.88), and F (fast contractions) (P = 0.19) values were statistically similar in both the groups. Multivariate analysis (n = 141) showed that higher weight (odds ratio [OR] 1.047 [1.018-1.076]; P < 0.001) and gravidity rates (OR 1.627 [1.169-2.266]; P < 0.01) were risk factors for UI and higher weight (OR 1.046 [1.010-1.084]; P = 0.01), and presence of comorbidities (OR 8.75 [1.07-71.44]; P < 0.01) were risk factors for POP in the POI group; there was no variable that was associated with FI. Women with POI did not have significant differences when compared with the control group regarding the prevalence of PFD and pelvic floor muscle assessment. Having higher weight and gravidity rates were associated with self-reported UI, while the presence of comorbidities and higher weight were risk factors for POP in the POI group. : Video Summary:http://links.lww.com/MENO/A555.

Validation of the Health Literacy in Dentistry scale in Brazilian adults

To perform cross-cultural adaptation and validation of the Health Literacy Dental scale (HeLD) in Brazilian adults. The HeLD instrument was translated and cross-culturally adapted to the Brazilian Portuguese language to create longer (HeLD-29) and shorter (HeLD-14) versions. The reliability and validity of these versions were assessed in a sample of 603 adults living near six primary care units in the city of Piracicaba, São Paulo, Brazil. Both versions of HeLD demonstrated high internal reliability, acceptable convergent validity and discriminant validity. However, the confirmatory factor analysis showed that only HeLD-14 demonstrated satisfactory goodness of fit. There were associations between HeLD-14 scores and social demographic characteristics, general and oral health and oral health-related behaviours. Higher scores were observed for the total HeLD-14 and/or individual components of HeLD-14 among women, ethnic white subjects, those with high educational attainment, those with higher income, those reporting toothbrushing twice or more daily, regular dental attenders, those who usually attended for dental care for a check-up, those with excellent or very good self-ratings of general health, those with excellent or very good self-ratings of oral health, and those without tooth extraction and oral health impact. The Brazilian version of HeLD-14 was demonstrated to be a reliable and valid instrument for measuring broad aspects of oral health literacy in the adult Brazilian population.

Cross-cultural adaptation of the Clear Communication Index to Brazilian Portuguese

ABSTRACTOBJECTIVETo perform a cross-cultural adaptation of the Clear Communication Index instrument from the Centers for Disease Control and Prevention (CDC-CCI) from English to Brazilian Portuguese.METHODSThis study comprised initial discussion about the conceptual equivalence of the instrument by a committee formed by experts on health education. We performed translations, synthesis of translations, back-translations, revision by the committee, and linguistic revision. Semantic equivalence was obtained by analyzing the referential and general meaning of each item by the committee, resulting in a pre-final version of the instrument. Subsequently, thirty professionals with health sciences degrees performed a pre-test. These professionals used the pre-final version of the instrument to assess a health education material. A questionnaire was applied to evaluate the acceptability of the instrument, the understanding of each of the 20 items, as well as the individual and professional variables. We analyzed the scores attributed to the health education material, the variables related to healthcare professionals, the proportions of the acceptability of the instrument, and the comprehension of each item.RESULTSAfter we obtained the conceptual equivalence of the instrument, the committee of experts, the instrument’s main author, and the linguist produced the pre-final version using two translations, a synthesis of the translations, and two back-translations. A general equivalence was maintained in 15 of the 20 items (75%), four of the items were slightly altered (20%), and one item was very altered (5%). Nineteen items presented referential equivalence or near equivalence (95%). We then carried out with the pre-test, in which the professionals used the pre-final version. Two items in the domains of “risks” and “main message” were unclear and needed to be revised.CONCLUSIONThe process of cross-cultural adaptation of the Clear Communication Index provided an adapted version to the Brazilian Portuguese language.

Nesse trabalho descrevemos um caso de ensino do processo escolar de uma aluna com surdez (PS) do Ensino Fundamental de uma escola de Macapá/AP, mediado por práticas do Atendimento Educacional Especializado (AEE). A aluna, em questão, é do sexo feminino, tem 11 anos de idade, estuda na escola desde o 1º ano, atualmente matriculada e frequentando o 5º ano. Segundo o pai, ela é a filha primogenita, usou aparelho auditivo e não se acostumou, participou de sessões de fonoterapia e não desenvolveu a oralização. Contudo, ele não soube informar o grau da surdez da filha. Na escola, a aluna frequenta a Sala de Recursos Multifuncional (SRM), onde recebe o AEE, em Língua de Sinais Brasileira – LIBRAS (L1) e Língua Portuguesa (L2) três vezes por semana, no contraturno. Desenvolve atividades escritas e jogos com rescursos visuais e no computador, de maneira contextualizada. O problema de comunicação na escola e na família foi solucionado com o desenvolvimento de um projeto na sala de aula, uma vez por semana, e aos sábados com os funcionários da escola e o pai da aluna. A professra da sala comum inseriu a LIBRAS e o uso de imagens nas aulas; os alunos e a docente passaram a interagir em LIBRAS. Portanto, abarreira da comunicação foi eliminada e o ensino em L1 e L2 se tornou acessível e significativo.

Measurement properties from the Brazilian Portuguese version of the QUIP-RS

Parkinson’s disease (PD) has numerous motor and non-motor symptoms. Among non-motor manifestations impulse control disorders (ICDs) stand out. ICDs include compulsions for gambling, shopping, eating, and sexual behavior, and “related disorders” such as hobbyism, simple motor activities, and dopamine dysregulation syndrome. There is no rating scale translated and adapted transculturally into Brazilian Portuguese language. Therefore, we cross-culturally adapted and investigated the measurement properties of the Brazilian version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease-Rating Scale (QUIP-RS). Fifty-three patients participated in the study. Inter-evaluator and test–retest (patient and health professional) reliabilities (intraclass correlation coefficient) were all excellent (0.93, 0.93, and 0.99). The internal consistency was high (α = 0.92). The Minimal detectable change (MDC) value was 5.8 (patient) and 2.3 (health professional) points. There was a floor, but no ceiling, effect. In summary, the Brazilian version of the QUIP-RS has high reliability and content validity.

Translation, Cross-cultural Adaptation and Reliability of Brazilian portuguese version of the DRAM Questionnaire for Psychometric Evaluation in Low Back Pain.

Objective Based on studies regarding pain physiology and its relation to emotional distress conditions, psychological evaluation became essential to determine the most favorable patient profiles to distinct therapeutic approaches. The Distress Risk Assessment Method (DRAM) has been developed as a screening instrument for patients with lumbar pain, classifying them in subgroups as normal, at risk, distressed somatic and distressed depressive, based on the two components of DRAM scores (Modified Somatic Perception Questionnaire [MSPQ] and Zung questionnaires). The objective of the present study is to translate and culturally adapt the DRAM to the Brazilian Portuguese language, and to determine the reliability of the final version. Methods As proposed by the International Quality of Life Assessment (IQOLA) method, a Brazilian Portuguese version of the DRAM has been applied to a sample of 85 individuals from 3 participant centers. Results The results confirmed the reliability and reproducibility of the DRAM in its Brazilian Portuguese final version: Cronbach alpha of 0.815 (MSPQ) and 0.794 (Zung) and intraclass correlation coefficient (ICC) of 0.688 (MSPQ) and 0.659 (Zung). Conclusion The presented DRAM version in Brazilian Portuguese is reliable and is available to clinical practice use.

Initial Validity and Reliability of the Portuguese Borg Rating of Perceived Exertion 6-20 Scale

ABSTRACTThe aims of this study were to perform the cross-cultural adaptation of the Borg Rating of Perceived Exertion (RPE) 6–20 Scale to Brazilian Portuguese language and to start testing its validity and reliability. After performing the cross-cultural adaptation of the Scale, concurrent and discriminative validity, and reliability were determined on a treadmill in young (18–30 years) and older adult women (60–75 years). Considering young and older adult women, RPE presented high and moderate positive correlation with heart rate and high and low positive correlation with oxygen consumption, respectively. Older adult women presented RPE (11 ± 2) significantly higher than young ones (8 ± 1) exercising at the same absolute intensity. Intraclass coefficient correlation was excellent for RPE to young and older adult women. The Scale presented concurrent validity only to young adult women, whereas it presented discriminative validity between such groups of women. Moreover, the scale is reliable to young and older adult women.

Clinical Frailty Scale: translation and cultural adaptation into the Brazilian Portuguese language

Frailty is a biological syndrome that causes adverse events in the health of older adults. However, the Clinical Frailty Scale has not yet been culturally adapted and validated into Brazilian Portuguese language. Our aim was to translate, reproduce and validate the Clinical Frailty Scale (CFS) for the Brazilian Portuguese language. An observational cross-sectional study with senior patients was conducted between Jan 2018 and Nov 2018. Volunteers aged >60 and living in Brazil. The translation and cultural adaptation of the CFS into the Portuguese language, the principles and good practices were followed. To conduct the validation and determine the reproducibility of an inter-observer evaluation, the patients answered the scale questions in Portuguese on two occasions, delivered by two separate examiners and separated by a 10-minute interval, on their first visit; the 36-item Short Form Survey quality-of-life questionnaire (SF-36) was also applied. Seven days later, a second visit was undertaken to perform an intra-observer reproducibility assessment. A total of 66 older individuals were enrolled (72 ± 8 years), the majority of which did not present frailty (63.6%) and reported a low physical limitation level in the SF-36. The CFS showed a significant correlation with the SF-36 quality-of-life questionnaire (r= -0.663; p<0.0001) and no statistical difference was observed between intra-rater (p=0.641) and inter-rater (p=0.350) applications, demonstrating the reproducibility and applicability of the instrument. The standard error estimate (SEE) was evaluated and there were no differences between the CFS and the SF-36 (SEE= 1.13 points). The Brazilian Portuguese language version of the CFS is a valid, reproducible and reliable instrument for evaluating the impact of frailty on the lives of senior patients.

Feasibility Analysis in Tracking Algorithms for Pattern Recognition Through the Lip Articulators

Problems in speech and basic emission of vocal sounds are commonly observed in children, however the task of identifying the origin of such disability is complex and prolonged, due to the generic aspect, if by irregular learning or neurobiological disorder, thus causing, in some situations, constant social exclusion. Therefore, it is proposed to use Tracking Algorithms consolidated in specific literature (ACF, Boosting, MIL, Median Flow, KCF, KLT, CRST) for a feasibility analysis in complex computational implementations in the anatomy of human vocal tract from sagittal images. These algorithms are used for understanding the kinematic configuration of multiple dynamic objects and their movements, represented by the upper and lower lips (consequently the “lip distance” at the moment of speech), using Brazilian Portuguese language, for the extraction and recognition of patterns automatically. The patterns can be used in innovative applications in therapy for children with poor articulation in the vocal tract, based on “gaps” and specific difficulties in speech.

Mathematical knowledge and language in deaf students: The relationship between the recitation of a numerical sequence and Brazilian Sign Language proficiency

Abstract The present study investigated recitation skills, constitutive of the number concept, and their relationship with language skills in the Brazilian Sign Language. Different levels of numerical sequence recitation were identified in 1st to 3rd grade deaf students attending a bilingual Elementary School (Brazilian Portuguese and Brazilian Sign Language), as well as the association between numerical recitation and schooling. The ability to enumerate was associated with specific levels of receptive and expressive language in Brazilian Sign Language.

Measuring suicide risk in the elderly with non-institutionalized depression: an integrative review.

Analyze the state of the art about instruments, at national and international levels, for assessing the risk of suicide in elderly people with depression assisted in the community. Integrative review of 38 complete articles, published in journals indexed in the databases: US National Library of Medicine (PubMed Central), Scopus, CINAHL and Web of Science, located using controlled descriptors combined with Boolean operators: elderly OR aged OR older OR elder OR geriatric AND depression AND suicide AND risk assessment. Six instruments were found, all international and published in the English language, in order to identify suicidal behavior and ideation in the elderly. Of these, two are specific scales for assessing the risk of suicide in the elderly in the community: 5-item GDS subscale and Geriatric Suicide Ideation Scale. With the scarcity of national instruments to assess such risk, research is recommended to cross-culturally adapt one of these scales to the Brazilian Portuguese language.

Geolinguistic studies in Brazil in five phases: From the Viscount of Pedra Branca to the atlases of traditional communities’ speech

Considering the expansion of Dialectology in Brazil, which, in the 19th century, presented the first clues with the Viscount of Pedra Branca’s publication about the Brazilian Portuguese language compared to the European Portuguese spoken in Portugal, this paper presents the stages of development of the studies carried out since then and lists not only the periods that preceded Brazilian Geolinguistics, but the research that culminated with the publication of States Linguistic Atlases, the publication of the Linguistic Atlas of Brazil in 2014, idealized fifty years before, and the presentation of other documents already completed or designed, thus contemplating the entire Brazil length and completing the fourth phase of Geolinguistic studies. Twelve atlases were published in this phase, whose pioneering role was for Bahia speech, in 1963, and advanced in the work related to Minas Gerais (1977), Paraíba (1977). 1984), Sergipe (1987 and 2002), Paraná (1994), The Southern Region (2002), Pará (2004), Ceará (2009), Goiás (2015), Pernambuco (2016) and Amapá (2017). However, in recent years, researches of linguistic varieties in traditional communities, such as Indigenous, Fishermen and Quilombolas, as are named the descendants and remaining of communities formed by enslaved fugitives, has drawn the attention of researchers and the elaboration of linguistic atlases involving these culturally differentiated people speeches already signals the fifth phase of Geolinguistic studies in the country. Thus, it is intended to present a description of the works, their methodological constitution and a brief overview of the products of these works, which cataloged, at the time of their conclusion, presented specific linguistic marks of the speech of each state and informants’ profiles that allowed the verification of sociocultural interferences.

Measuring Students' Perceptions of the Medical School Learning Environment: Translation, Transcultural Adaptation, and Validation of 2 Instruments to the Brazilian Portuguese Language.

Background:Although learning environment (LE) is an important component of medical training, there are few instruments to investigate LE in Latin American and Brazilian medical schools. Therefore, this study aims to translate, adapt transculturally, and validate the Medical School Learning Environment Scale (MSLES) and the Johns Hopkins Learning Environment Scale (JHLES) to the Brazilian Portuguese language.Method:This study was carried out between June 2016 and October 2017. Both scales have been translated and cross-culturally adapted to Brazilian Portuguese Language and then back translated and approved by the original authors. A principal components analysis (PCA) was performed for both the MSLES and the JHLES. Test–retest reliability was assessed by comparing the first administration of the MSLES and the JHLES with a second administration 45 days later. Validity was assessed by comparing the MSLES and the JHLES with 2 overall LE perception questions; a sociodemographic questionnaire; and the Depression, Anxiety, and Stress Scale (DASS-21).Results:A total of 248 out of 334 (74.2%) first- to third-year medical students from a Brazilian public university were included. Principal component analysis generated 4 factors for MSLES and 7 factors for JHLES. Both showed good reliability for the total scale (MSLES α = .809; JHLES α = .901), as well as for each subdomain. Concurrent and convergent validity were observed by the strong correlations found between both scale totals (r = 0.749), as well as with both general LE questions: recommend the school to a friend (MSLES: r = 0.321; JHLES: r = 0.457) and overall LE rating (MSLES: r = 0.505; JHLES: r = 0.579). The 45-day test–retest comparison resulted in a Pearson correlation coefficient of 0.697 for the JHLES and 0.757 for the MSLES.Conclusions:Reliability and validity have been demonstrated for both the MSLES and the JHLES. Thus, both represent feasible options for measuring LE in Brazilian medical students.

The Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living questionnaire: construct validity, reliability, and measurement error.

ABSTRACTObjective:To test the construct validity, reliability, and measurement error of the Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living (MRADL) questionnaire in patients with COPD. Methods:We evaluated 50 patients with COPD, among whom 30 were men, the mean age was 64 ± 8 years, and the median FEV1 as a percentage of the predicted value (FEV1%predicted) was 38.4% (interquartile range, 29.1-57.4%). Pulmonary function and limitations in activities of daily living (ADLs) were assessed by spirometry and by face-to-face application of the MRADL, respectively. For the construct validity analysis, we tested the hypothesis that the total MRADL score would show moderate correlations with spirometric parameters. We analyzed inter-rater reliability, test-retest reliability, inter-rater measurement error, and test-retest measurement error. Results:The total MRADL score showed moderate correlations with the FEV1/FVC ratio, FEV1 in liters, FEV1%predicted, and FVC%predicted, all of the correlations being statistically significant (r = 0.34, r = 0.31, r = 0.42, and r = 0.38, respectively; p < 0.05 for all). For the reliability and measurement error of the total MRADL score, we obtained the following inter-rater and test-retest values, respectively: two-way mixed-effects model intraclass correlation coefficient for single measures, 0.92 (95% CI: 0.87-0.96) and 0.89 (95% CI: 0.81-0.93); agreement standard error of measurement, 1.03 and 0.97; smallest detectable change at the individual level, 2.86 and 2.69; smallest detectable change at the group level, 0.40 and 0.38; and limits of agreement, −2.24 to 1.96 and −2.65 to 2.69. Conclusions:In patients with COPD in Brazil, this version of the MRADL shows satisfactory construct validity, satisfactory inter-rater/test-retest reliability, and indeterminate inter-rater/test-retest measurement error.

Cultural Adaptation and Validation of the Methotrexate Intolerance Severity Score in Brazilian Portuguese for Adults With Rheumatoid Arthritis.

The Methotrexate Intolerance Severity Score (MISS) questionnaire is used to identify intolerance to methotrexate (MTX), but it is not available in the Brazilian Portuguese language. The aim of this study was to adapt and validate the MISS in Brazilian Portuguese. The Brazilian Portuguese version of the MISS was developed following the Guidelines for the Process of Cross-cultural Adaptation of Self-report Measures. The new version was tested in 120 patients with rheumatoid arthritis. For the reliability assessment, the Cronbach α coefficient was used. The receiver operating characteristic curve was constructed with the objective of finding the best cutoff point for MTX intolerance and weighing the sensitivity and specificity. The concordance among the results was analyzed using the κ coefficient and factorial analysis with varimax rotation. This methodological study developed and applied a culturally acceptable Brazilian Portuguese version of the MISS. The MISS questionnaire presented internal consistency classified as "very good" because Cronbach α is equal to 0.83 (95% confidence interval, 0.79-0.87). The suitability of the data for factorial analysis was demonstrated using the Kaiser-Meyer-Olkin sample adequacy test (KMO = 0.723) and Bartlett sphericity test (χ2 = 499.98, p < 0.001). It was observed that a factorial analysis with 3 factors is preferred; the receiver operating characteristic curve of the MISS score was considered the cutoff point at 6 points (sensitivity 100% and specificity 89.4%). The Brazilian Portuguese version of the MISS is valid and reliable for the detection of MTX intolerance in clinical practice.

Validation for Brazilian Portuguese language of the Hong Kong Oral Health Literacy Assessment Task for Paediatric Dentistry (BOHLAT-P).

Oral health literacy (OHL) is associated with oral health outcomes. To validate the Brazilian Portuguese version of the Hong Kong OHL Assessment Task for Paediatric Dentistry (HKOHLAT-P). We performed cross-cultural adaptation of the HKOHLAT-P. A sample of 200 pre-schoolers and caregivers from Campina Grande, Brazil completed the Brazilian HKOHLAT-P (BOHLAT-P), sociodemographic questionnaire, the Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS), and the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30). Child dental caries was assessed. Instrument reliability was measured by internal consistency (Cronbach's alpha) and test-retest (ICC). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) evaluated dimensionality. Regression models tested associations between BOHLAT-P and exploratory variables (P<.05). BOHLAT-P demonstrated excellent reliability (Cronbach's alpha=0.92; ICC=0.95). BOHLAT-P and BREALD-30 scores (r=.71), number of schooling years (r=.60), and reading hours (r=.34) were positively correlated. BOHLAT-P and B-ECOHIS scores (r=-.22), and BOHLAT-P scores and number of cavitated teeth (r=-.15) were negatively correlated. After controlling for confounding variables, BOHLAT-P scores were not associated with caries or number of teeth with cavitated caries. BOHLAT-P is a valid and reliable instrument to assess the OHL of Brazilian parents.
