Translation and Cross-Cultural Adaptation of the Brazilian Version of the International Knee Documentation Committee Subjective Knee Form Validity and Reproducibility

Background: The perception of improvement by a patient has assumed a central role in functional evaluation after a variety of knee problems. One of the instruments most used in clinical research is the International Knee Documentation Committee (IKDC) Subjective Knee Form because its psychometric properties are considered to be excellent. Nonetheless, this questionnaire was originally developed for use in the English language. Therefore, to use this questionnaire in the Brazilian population, it is essential to translate and validate it. Purpose: The aim of this study was to translate the IKDC Subjective Knee Form into a Brazilian version and to test its validity and reproducibility. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: The translation of the original IKDC Subjective Knee Form into a Brazilian version was accomplished in accordance with the American Orthopaedic Society for Sports Medicine guidelines and was tested in 32 patients with knee pathologic conditions to develop the first Brazilian version. To test validity and reproducibility, 117 patients with several knee complaints completed the Brazilian IKDC Subjective Knee Form, the Short Form 36 (SF-36), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Lysholm score. From these patients, 85 were retested within a week to achieve reproducibility. The validation was addressed by correlating the Brazilian IKDC Subjective Knee Form to the other outcome measures. The reproducibility was tested by measuring internal consistency, test-retest reliability, and agreement. Results: The Brazilian IKDC Subjective Knee Form was highly related to the physical component summary of the SF-36, the Lysholm score, and the WOMAC, and weakly related to the mental component summary of SF-36 (r=.79, .89, .85, and .51, respectively). The internal consistency was strong, with a Cronbach a value of .928 and .935 in the test and retest assessment, respectively. The test-retest reliability proved to be excellent, with a high value of the intraclass correlation coefficient (.988), as well as the agreement, demonstrated by the low differences between the means of the test and retest, and the short limit of agreement, observed in the Altman-Bland and survival-agreement plots. Conclusion: The results of this study provide evidence that the Brazilian IKDC Subjective Knee Form has psychometric properties similar to the original version. In addition, it was a reliable evaluation instrument for patients with knee-related problems.

Functional Disability in Alzheimer Disease A Validation Study of the Brazilian Version of the Disability Assessment for Dementia (DAD-Br)

Background: The assessment of activities of daily living (ADL) is important both for the diagnosis and staging of dementia. The objective of this study was to verify the applicability and validity of the Brazilian version of the Disability Assessment for Dementia (DAD-Br). Methods: The DAD was applied to caregivers of 89 patients with probable Alzheimer disease (AD) and to 40 elderly individuals without cognitive impairment (controls). We assessed the construct validity of the scale and its diagnostic accuracy (sensitivity, specificity, and predictive value). In addition, intergroup and intragroup analyses were conducted to characterize patient performance on basic and instrumental ADL and to determine underlying deficits (initiation, planning, or effective execution). Results: AD patients and controls had mean ages of 76.4 +/- 6.9 years and 74.5 +/- 7.3 years (P = 0.08), respectively. Mean Mini-Mental State Examination scores were 17.4 +/- 5.0 and 26.1 +/- 5.1 (P < 0.001) and scores on the DAD were 68.4 +/- 19.0 and 99.8 +/- 0.9 (P < 0.001), for patients and controls, respectively. The DAD scale showed good internal consistency (Cronbach alpha = 0.77) and correlation with the Mini-Mental State Examination (r = 0.44; P < 0.001). The AD group did better on basic ADL than on instrumental ADL (P < 0.001). As expected, controls did not exhibit significant deficits on the items evaluated. Conclusion: The Brazilian version of the DAD is an adequate and reliable tool for assessing functional ability in AD patients.

RELIABILITY AND VALIDITY OF THE PHOTOGRAMMETRY FOR SCOLIOSIS EVALUATION: A CROSS-SECTIONAL PROSPECTIVE STUDY

Objective: The purpose of this study was to investigate the reliability and validity of photogrammetry in measuring the lateral spinal inclination angles. Methods: Forty subjects (32 female and 8 males) with a mean age of 23.4 +/- 11.2 years had their scoliosis evaluated by radiographs of their trunk, determined by the Cobb angle method, and by photogrammetry. The statistical methods used included Cronbach alpha, Pearson/Spearman correlation coefficients, and regression analyses. Results: The Cronbach a values showed that the photogrammetric measures showed high internal consistency, which indicated that the sample was bias free. The radiograph method showed to be more precise with intrarater reliabilities of 0.936, 0.975, and 0.945 for the thoracic, lumbar, and thoracolumbar curves, respectively, and interrater reliabilities of 0.942 and 0.879 for the angular measures of the thoracic and thoracolumbar segments, respectively. The regression analyses revealed a high determination coefficient although limited to the adjusted linear model between the radiographic and photographic measures. It was found that with more severe scoliosis, the lateral curve measures obtained with the photogrammetry were for the thoracic and lumbar regions (R = 0.619 and 0.551). Conclusions: The photogrammetric measures were found to be reproducible in this study and could be used as Supplementary information to decrease the number of radiographs necessary for the monitoring of scoliosis.

Performance of Brazilian long and short IQCODE on the screening of dementia in elderly people with low education

Background: Dementia screening in elderly people with low education can be difficult to implement. For these subjects, informant reports using the long (L) (26 items) and short (C) (16 items) versions of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) can be useful. The objective of the present study was to investigate the performance of Brazilian versions of the IQCODE L, S and a new short version (SBr) (15 items) in comparison with the Mini-mental State Examination (MMSE) for dementia screening in elderly people with low education. Methods: Thirty-four patients with mild to moderate dementia, diagnosed according to ICD-10 criteria, and 57 controls were evaluated and divided into three groups based on their socioeconomic status and level of education. Patients were evaluated using the MMSE and the informants were interviewed using the IQCODE by interviewers blind to the clinical diagnosis. Results: Education was correlated with MMSE results (r = 0.280, p = 0.031), but not with the versions of the IQCODE. The performance of the instruments, evaluated by the ROC curves, was very similar, with good internal consistency (Cronbach`s alpha = 0.97). MMSE correctly classified 85.7% of the subjects while the three IQCODE versions (L, S and SBr) correctly classified 91.2% of the subjects. Conclusions: The long, short and the new short Brazilian IQCODE versions can be useful as a screening tool for mild and moderate patients with dementia in Brazil. The IQCODE is not biased by schooling, and it seems to be an adequate instrument for samples with low levels of education.

Reliability and validity of the Brazilian-Portuguese version of the Burns Specific Pain Anxiety Scale (BSPAS)

Background: Pain and anxiety are a common problem in all recovery phases after a burn. The Burns Specific Pain Anxiety Scale (BSPAS) was proposed to assess anxiety in burn patients related to painful procedures. Objectives: To assess internal consistency, discriminative construct validity, dimensionality and convergent construct validity of the Brazilian-Portuguese version of the Burns Specific Pain Anxiety Scale. Design: In this cross-sectional study, the original version of the BSPAS, adapted into Brazilian Portuguese, was tested for internal consistency (Cronbach`s Alpha), discriminative validity (related to total body surface area burned and sex), dimensionality (through factor analysis), and convergent construct validity (applying the Visual Analogue Scale for pain and State-Anxiety-STAI) in a group of 91 adult burn patients. Results: The adapted version of the BSPAS displayed a moderate and positive correlation with pain assessments: immediately before baths and dressings (r = 0.32; p < 0.001), immediately after baths and dressings (r = 0.31; p < 0.001) and during the relaxation period (r= 0.31; p < 0.001) and with anxiety assessments (r = 0.34; p < 0.001). No statistically significant differences were observed when comparing the mean of the adapted version of the BSPAS scores with sex (p = 0.194) and total body surface area burned (p = 0.162) (discriminative validity). The principal components analysis applied to our sample seems to confirm anxiety as one single domain of the Brazilian-Portuguese version of the BSPAS. Cronbach`s Alpha showed high internal consistency of the adapted version of the scale (0.90). Conclusion: The Brazilian-Portuguese version of the BSPAS 9-items has shown statically acceptable levels of reliability and validity for pain-related anxiety evaluation in burn patients. This scale can be used to assess nursing interventions aimed at decreasing pain and anxiety related to the performance of painful procedures. (c) 2010 Elsevier Ltd. All rights reserved.

Is the Full Version of the AUDIT Really Necessary? Study of the Validity and Internal Construct of Its Abbreviated Versions

Background: This study was aimed at assessing the psychometric qualities of the abbreviated versions of the Alcohol Use Disorders Identification Test (AUDIT-3, AUDIT-4, AUDIT-C, AUDIT-PC, AUDIT-QF, FAST, and Five-Shot) and at comparing them to the 10-item AUDIT and the CAGE in 2 samples of Brazilian adults. Methods: The validity and internal consistency of the scales were assessed in a sample of 530 subjects attended at an emergency department and at a Psychosocial Care Center for Alcohol and Drugs. The Structured Clinical Interview for DSM-IV was used as the diagnostic comparative measure for the predictive validity assessment. The concurrent validity between the scales was analyzed by means of Pearson`s correlation coefficient. Results: The assessment of the predictive validity of the abbreviated versions showed high sensitivity (of 0.78 to 0.96) and specificity (of 0.74 to 0.94) indices, with areas under the curve as elevated as those of the AUDIT (0.89 and 0.92 to screen for abuse and 0.93 and 0.95 in the screening of dependence). The CAGE presented lower indices: 0.81 for abuse and 0.87 for dependence. The analysis of the internal consistency of the AUDIT and its versions exhibited Cronbach`s alpha coefficients between 0.83 and 0.94, while the coefficient for the CAGE was 0.78. Significant correlations were found between the 10-item AUDIT and its versions, ranging from 0.91 to 0.99. Again, the results for the CAGE were satisfactory (0.77), although inferior to the other instruments. Conclusions: The results obtained in this study confirm the validity of the abbreviated versions of the AUDIT for the screening of alcohol use disorders and show that their psychometric properties are as satisfactory as those of the 10-item AUDIT and the CAGE.

Validity of a Brazilian version of the Zung self-rating depression scale for screening of depression in patients with Parkinson`s disease

Introduction: Parkinson`s disease (PD) is a neurodegenerative disorder with prominent motor manifestations and many other non-motor symptoms that significantly decrease quality-of-life and are frequently under-recognized, for example depression. Objective: To study the validity of a Brazilian version of the Zung Self-rating Depression Scale (SDS) for the diagnosis of depression in patients with PD. Methods: We evaluated 78 consecutive non demented patients over the age of 40 with diagnosis of PD at a Movement Disorders Outpatient Clinic, who could read and understand questionnaires. They completed the SIDS and the Geriatric Depression Scale with 15 items (GDS-15). The diagnosis of depression was made after a structured clinical interview based on DSM-IV criteria for the diagnosis of major depression (SCID-CV). Results: The prevalence of major depression was 23.1%. Cronbach`s alpha was 0.73 and the area under the ROC curve was 0.93 for the SDS. The score index of 55 had a sensitivity of 88.9% and a specificity of 83.3% for the diagnosis of depression. The total scores of the SDS and GDS-15 were highly correlated (0.652, p < 0.0001) and correlated weakly with the scores of a motor scale. Discussion: The SIDS is a valid too] for screening depression in patients with PD since the specific SDS index of 55 is adopted. Two shortened versions could be used with good results.

Psychometric qualities of the Brazilian versions of the Fagerstrom Test for Nicotine Dependence and the Heaviness of Smoking Index

This study examined the psychometric properties of the Brazilian versions of the Fagerstrom Test for Nicotine Dependence (FTND) and the Heaviness of Smoking Index (HSI). The test-retest reliability of the FTND was assessed in a sample of 61 smoking university students, with a 15-day interval between assessments. The interrater reliability was examined in 30 smoking patients of a psychosocial care center for alcohol and drug users (PCC-AD). The reliability coefficient was estimated by the kappa and intraclass correlation coefficients. The predictive validity, internal consistency, and factor structure of the FTND and the HSI were evaluated by factor analysis in 271 smokers treated at an emergency unit and at the PCC-AD. The gold standard was the nicotine dependence criteria of DSM-IV, as assessed by the Structured Clinical Interview for DSM-IV. The FTND showed high reliability, with correlation coefficients of .92 for test-retest reliability and .99 for interrater reliability. Both the FTND and the HSI presented high levels of sensitivity and specificity. The internal consistency evaluation yielded a Cronbach`s alpha coefficient of .83 for the FTND and of .56 for the HSI. An exploratory factor analysis found 2 factors in the FTND, which were validated by a confirmatory factor analysis. The results obtained in this study confirm the validity and reliability of the Brazilian versions of the FTND and the HSI.

Construction and Validation of the Brazilian Questionario de Respostas Socialmente Habilidosas Segundo Relato de Professores (QRSH-PR)

Behavioral problems in preschool children are one of the most frequent motives for seeking psychological care by parents and caregivers. Instruments are considered necessary, created from a Social Skills Training theoretical-practical perspective, which may systematically assist the identification of social skills and behavioral deficits. helping professionals in the prevention and/or reduction of behavioral problems. The purpose of this study was to test the psychometric validity and reliability of an instrument for evaluation of Socially Skilled Responses. from a teacher`s perspective (QRSH-PR). For this purpose, 260 preschool children were evaluated. differentiated in subgroups without and without behavioral difficulties, based on the Child Behavior Scale (Escala de Comportamento Infantil/ECI-Professor). Studies were conducted for construct. discrimination. concurrent and predictive validity. The Cronbach Alpha was calculated to evaluate internal consistency. The obtained results pointed to positive indicators in reference to construct, discrimination, and predictive validity, and even for good internal consistency. indicating that the items consistently measure the construct of social skills, and differentiated children with and without behavioral problems. The questionnaire is considered to be gauged for evaluation of socially skilled responses from preschool children. and applicable in educational and clinical environments.

Validation of the Brazilian version of the quality of life scale for patients with Alzheimer`s disease and their caregivers (QOL-AD)

Quality of life (QOL) has been extensively studied in clinical trials and in research on chronic degenerative diseases and dementia. The aim of this study was to assess the reliability and construct validity of the Brazilian version of the QOL scale in Alzheimer`s disease (AD; QOL-AD). The QOL-AD was administered to 60 patients with mild or moderate AD and to their caregivers. The construct validation was accomplished through correlations amongst total scores of patients` and caregivers` reports on patients` quality of life (PQOL and C-PQOL, respectively), and data related to cognitive impairment, depressive symptoms, functional performance, behavioral disturbances and a generic instrument of quality of life (WHOQOL-brief), as well as correlation of total score of caregivers` reports on their own quality of life (CQOL) with the measurements cited above, QOL-AD patient reports, and depressive symptoms. The reliability was high for PQOL, C-PQOL, and CQOL versions (Cronbach`s alpha = 0.80, 0.83, and 0.86, respectively). We observed significant correlations in the construct validity of all three versions regarding the variables associated with the disease and also with WHOQOL-brief. The scale took, on average, six min for each version. The results indicate reliability and construct validity of the Brazilian version of the QOL-AD in the studied sample.

Os desafios da redu????o da pobreza e da desigualdade

A desigualdade de renda no Brasil vem declinando de forma cont??nua, ao mesmo em tempo que se verifica redu????o do n??vel de pobreza. Entre 2001 e 2004, o coeficiente de Gini (medida utilizada para calcular a desigualdade de distribui????o de renda) passou de 0,59 para 0,56 (quanto mais alto o coeficiente, maior a desigualdade). A melhoria decorrente dessa queda ??, al??m disso, mais bem percebida pela popula????o mais pobre.

Os gêneros de Bethylidae (Hymenoptera: Chrysidoidea) de quatro áreas de Mata Atlântica do Espírito Santo

Estudou-se a riqueza e abundância de gêneros de Bethylidae coletados em quatro áreas de mata de encosta da Mata Atlântica do Espírito Santo, com estados de preservação diferentes: Santa Maria de Jetibá (SMJ), Domingos Martins (DM), Pancas (P) e Atílio Vivácqua (AV). Foram coletados 2.840 espécimes alocados em 12 gêneros, sendo Lepidosternopsis Ogloblin e Bakeriella Kieffer citados pela primeira vez para esse estado. A riqueza dos táxons foi obtida através do procedimento Jackknife com auxílio do programa EstimateS. Curvas de acumulação de gêneros foram construídas para avaliar o esforço amostral. Os dados se ajustaram à distribuição geométrica e calculou-se o parâmetro k para comparar as localidades. O perfil genérico não foi equivalente em todas as localidades, e todas foram consideradas perturbadas. SMJ e DM apresentaram riqueza de gêneros maior em comparação com P e AV. As diferenças relatadas neste estudo para as áreas amostradas refletem o grau diferente de preservação das matas. Pseudisobrachium Kieffer e Dissomphalus Ashmead foram os gêneros mais abundantes em SMJ, DM e P e Anisepyris Kieffer em AV. Este estudo reforça o fato de Dissomphalus ser mais abundante em florestas tropicais úmidas e que o perfil genérico encontrado em AV assemelha-se a dados publicados para o cerrado.

Risco de infecção tuberculosa em agentes comunitários de saúde

Objetivo: Estimar o risco de infecção tuberculosa em agentes comunitários de saúde envolvidos no controle da doença. Métodos: Foi seguida uma coorte prospectiva, de abril de 2007 a maio de 2008, no município de Cachoeiro de Itapemirim, ES. A coorte foi composta por 61 agentes comunitários, divididos em não-expostos (n=37) e expostos (que acompanharam pacientes com tuberculose, n=24). Durante os 12 meses de seguimento, foi realizado teste tuberculínico, utilizando a tuberculina PPD RT23. Foi calculado o risco relativo e intervalo com 95% de confiança e foi avaliada a correlação entre a viragem tuberculínica e a história ocupacional dos agentes por meio do coeficiente de correlação de Pearson. Resultados: A incidência da viragem foi de 41,7% no grupo dos expostos e 13,5% no grupo dos não expostos. O risco anual de infecção foi de 52,8% no grupo dos expostos e de 14,4% no grupo dos não expostos (p= 0,013). Observou-se associação entre viragem tuberculínica e exposição a paciente com tuberculose (RR= 3,08; IC 95%: 1,201;7,914). Conclusões: Os agentes que acompanharam pacientes com tuberculose em suas rotinas de serviço apresentaram risco de infecção maior que aqueles que não acompanharam pacientes com essa doença. A implementação de medidas administrativas de biossegurança de rotina, entre as quais a prova tuberculínica, devem ser priorizadas, considerando o alto risco de infecção tuberculosa entre os agentes comunitários de saúde.

A evasão discente no contexto da reestruturação universitária : o caso dos cursos de Administração e Ciências Contábeis da Universidade Federal do Espírito Santo

O objetivo desta pesquisa foi levantar os motivos que influenciam a evasão discente em quatro cursos de graduação da Universidade Federal do Espírito Santo. A reestruturação universitária proposta pelo REUNI - Programa de Apoio a Planos de Expansão das Universidades Federais serviu como contexto ao estudo, pois instituiu diretrizes para o combate à evasão no ensino superior. O modelo de evasão de cunho sociológico proposto por Tinto (1997) baseou as análises realizadas nesta pesquisa porque toma a instituição como responsável por ações capazes de criar um ambiente de aprendizado necessário à permanência do estudante. A pesquisa de campo quali-quantitativa foi realizada com os alunos evadidos e com os coordenadores dos cursos de Administração Diurno e Ciências Contábeis Noturno e dos novos cursos Administração Noturno e Ciências Contábeis Vespertino. Foram alcançados 95 alunos evadidos e os quatro coordenadores, sendo aplicado questionário semiaberto aos alunos evadidos e feitas entrevistas semiestruturadas com os coordenadores. Dados do sistema acadêmico (SIE/UFES) foram utilizados para o levantamento das variáveis. Os números fornecem evidências de que o resultado da aprendizagem traduzido pelo desempenho acadêmico torna-se um forte causador da evasão por abandono. O baixo coeficiente de rendimento relacionou-se ao desligamento por abandono na maioria dos casos. Em relação às formas de evasão, a desistência e o desligamento por abandono totalizaram 87,4% dos casos, com maior incidência de evasão no segundo e terceiro ano do curso. O ponto crítico da evasão parece confirmar-se do 2º ao 5º semestre e 62% dos casos de evasão que se situaram nesse lapso temporal apresentaram coeficiente de rendimento de 0,00 a 3,00. Os resultados evidenciaram os motivos que mais influenciaram os alunos a deixar o curso: i) a necessidade de trabalhar enquanto frequentava o curso, ii) a descoberta de novos interesses; iii) a incompatibilidade entre os horários do trabalho e do curso; iv) a escolha da carreira profissional ainda muito jovem e v) a falta de orientação aos alunos sobre normas, penalidades, planejamento do curso, periodização, etc. e deficiências na comunicação institucional.

Análise espacial do padrão de introdução e disseminação da dengue nos municípios do Espírito Santo

O número de municípios infestados pelo Aedes aegypti no Estado do Espírito Santo vem aumentando gradativamente, levando a altas taxas de incidência de dengue ao longo dos anos. Apesar das tentativas de combate à doença, esta se tornou uma das maiores preocupações na saúde pública do Estado. Este estudo se propõe a descrever a dinâmica da expansão da doença no Estado a partir da associação entre variáveis ambientais e populacionais, utilizando dados operacionalizados por meio de técnicas de geoprocessamento. O estudo utilizou como fonte de dados a infestação pelo mosquito vetor e o coeficiente de incidência da doença, as distâncias rodoviárias intermunicipais do Estado, a altitude dos municípios e as variáveis geoclimáticas (temperatura e suficiência de água), incorporadas a uma ferramenta operacional, as Unidades Naturais do Espírito Santo (UNES), representadas em um único mapa operacionalizado em Sistema de Informação Geográfica (SIG), obtido a partir do Sistema Integrado de Bases Georreferenciadas do Estado do Espírito Santo. Para análise dos dados, foi realizada a Regressão de Poisson para os dados de incidência de dengue e Regressão Logística para os de infestação pelo vetor. Em seguida, os dados de infestação pelo mosquito e incidência de dengue foram georreferenciados, utilizando como ferramenta operacional o SIG ArcGIS versão 9.2. Observou-se que a pluviosidade é um fator que contribui para o surgimento de mosquito em áreas não infestadas. Altas temperaturas contribuem para um alto coeficiente de incidência de dengue nos municípios capixabas. A variável distância em relação a municípios populosos é um fator de proteção para a incidência da doença. A grande variabilidade encontrada nos dados, que não é explicada pelas variáveis utilizadas no modelo para incidência da doença, reforça a premissa de que a dengue é condicionada pela interação dinâmica entre muitas variáveis que o estudo não abordou. A espacialização dos dados de infestação pelo mosquito e incidência de dengue e as Zonas Naturais do ES permitiu a visualização da influência das variáveis estatisticamente significantes nos modelos utilizados no padrão da introdução e disseminação da doença no Estado.
