The present study aimed to estimate the parameters of the Varieties of Sadistic Tendencies (VAST) items through the item response theory (IRT), specifically using the Samejima's graduated response model. For this purpose, 396 participants of both sexes were included, with a mean age of 26.93 (SD = 8.91). Participants responded to the following instruments: (1) Varieties of Sadistic Tendencies and (2) sociodemographic questionnaire. Initially, a confirmatory factor analysis (CFA) was performed, which identified a two-dimensional model with adequate fit indicators (CFI= .97; TLI= .97; RMSEA= .04). Thus, the item parameters were calculated for each dimension separately. The results indicated that the dimension items showed good discrimination, information breadth, and a good range of response thresholds. The conclusion is that the item parameters of VAST provide information that allows a better interpretation of its scores. [ABSTRACT FROM AUTHOR]

The first definition of presenteeism was limited to individuals who attended work despite being unwell. Over the past 15 years, other perspectives have expanded the concept to encompass any non-work-related factors influencing behavior during working hours. This research aims to redefine presenteeism within the context of healthcare workers' behaviors and contribute to the literature by introducing a measurement scale. The study involved 431 healthcare professionals across nine public and four private/foundation hospitals. Presenteeism was associated positively with burnout and negatively with happiness at work. Younger people showed higher levels of presenteeism compared to their older counterparts, as did those who worked nine hours or more per day. Although the scale was applied to healthcare professionals, its framework holds potential for use in other areas. [ABSTRACT FROM AUTHOR]

Background: The Demand Control Support model is useful for studying work-related stress. The combination of high demand and a low level of control generates “job strain” (“job iso-strain” if poor support is added), with implications for the worker’s health and well-being. The aims of this study were to adapt, examine the factor structure of, and determine the reliability of, the Demand Control Support Questionnaire (DCSQ) short version for European Portuguese (DCSQ-PT). Methods: The scale was translated into Portuguese following a rigorous process and then applied to 501 workers from various professional sectors. An online survey was used to collect sociodemographic, professional, and Demand Control Support data. Validation was based on reliability and validity tests. Results: The mean age of the sample was 41.8 ± 10.3 years, and 50.1% of the participants were female. The results reveal good reliability (Cronbach’s alpha = 0.807) and validity. Confirmatory factor analyses demonstrated that a four-factor solution of the DCSQ-PT scale had a good fit to the data, as was the case for the original scale. The DCSQ-PT© with 16 items is composed of the following factors: social support at work; psychological demands; skill discretion; and decision authority. Conclusions: This validation allows an instrument to be obtained with 16 items for studying work-related stress in Portuguese workers.

Complaints about subjective cognitive changes are common in clinical consultations with individuals over 50 years old and are considered a predictive criterion for the onset of cognitive decline. The assessment of these complaints through questionnaires is infrequent due to the limited number available in the literature. Furthermore, most of them focus exclusively on the evaluation of amnestic changes and not on overall cognition. It is an instrumental study that allowed estimating the evidence of validity and reliability of the CCC questionnaire designed by Salazar and Maldonado (2020). The sample consisted of 258 individuals aged between 50 and 80 years without a diagnosis of cognitive impairment and mild cognitive impairment. An exploratory factor analysis was conducted, revealing correlations of 0.881 and 0.901 with criterion questionnaires and an internal consistency of the instrument with a Cronbach's alpha coefficient (a) of .973. The CCC questionnaire is useful for exploring subjective cognitive changes in adults. It is considered that it can be used in clinical consultations for a more comprehensive evaluation and as a predictor in detecting mild cognitive impairment. [ABSTRACT FROM AUTHOR]

Risk perception is a concept related to the decision-making process and allows people to perceive the hazards surrounding the context and choose the best preventive methods to avoid them. The COVID-19 pandemic was a remarkable era in which people had to adopt protective methods, such as social isolation, to reduce the possibility of being contaminated by the virus. This study covers the development, psychometric properties, and norms of a scale to assess Risk Perception regarding COVID-19 and Social Isolation. The analysis suggested good expert agreement regarding the adequacy of the scale content and items and factor analysis suggested two factors, called the emotional and cognitive domains. The composite reliability suggested the internal consistency of the scale and its factors. All the results of this study suggest that this scale presents evidence of construct validity, constituting a reliable instrument. This new instrument may be used to evaluate risk perception related to COVID-19 and Social Isolation. [ABSTRACT FROM AUTHOR]

Resumo Este trabalho apresenta uma análise da qualidade metodológica das revisões sistemáticas de literatura lusófonas, na área da Comunicação e Informação, utilizando princípios e técnicas desta metodologia comuns à análise de conteúdo, notadamente as relativas à replicabilidade e à confiabilidade. Para isso, 4 bases de indexação foram utilizadas: Web of Science, Scopus, DOAJ e SciELO, sob delimitação temporal específica (2010-2021). Mediante o desenvolvimento de um livro de códigos e realização de testes de confiabilidade, 49 trabalhos foram selecionados e analisados em relação a informações sobre (a) bases utilizadas; (b) termos de busca; (c) delimitação temporal (quantidade de anos); (d) número de trabalhos analisados; (e) critérios de inclusão e/ou exclusão; (f) replicabilidade; (g) confiabilidade. Os principais resultados indicam uma reduzida preocupação dos trabalhos analisados em incorporar ou reportar procedimentos responsivos à confiabilidade (n=3). Por outro lado, a maior parte dos estudos (n=40) mostrou-se, em linhas gerais, replicável. A principal inovação e contribuição desta pesquisa consistiu em propor e testar um procedimento de incremento da confiabilidade das revisões sistemáticas mediante consulta aos autores dos trabalhos revisados. Destaca-se, para além do caráter inovador de tal procedimento, os ganhos epistêmicos por ele trazidos. Discute-se, ao final, as implicações dos resultados para pesquisas futuras, indicando os possíveis ganhos que as estratégias metodológicas concebidas e testadas neste trabalho oferecem para balizar o rigor metodológico das revisões sistemáticas de literatura.

Introdução: Existem redes de cooperação internacional compostas por instituições de segurança pública para promoção, prevenção e repressão de crimes transnacionais organizados, as quais precisam de alguns fatores para que funcionem adequadamente. Objetivo: Analisar a percepção de confiabilidade dos adidos da Polícia Federal no compartilhamento de informações com os atores das instituições congêneres internacionais, em apoio às investigações de crimes. Métodos: A pesquisa é caracterizada como descritiva, transversal com abordagem qualitativa. Por amostragem censitária, foram realizadas entrevistas virtuais com adidos da Polícia Federal de 16 países, com apoio de roteiro semiestruturado. Os dados foram transcritos e submetidos à análise de conteúdo, sendo que algumas categorias foram estabelecidas a priori e outras a posteriori. Resultados: A percepção de confiabilidade da contraparte só é realizada quando a informação é classificada como sensível, e é suprimida quando a instituição tem boa reputação. Percebeu-se extrema relevância da presença física do adido, principalmente nas interações com atores confiáveis de instituições cuja reputação é negativa. Constatou-se a variação nos critérios de análise da percepção de confiabilidade adotadas pelos adidos referentes a competência, integridade e benevolência, sendo que a integridade foi o critério priorizado pela moda. Conclusões: A percepção de confiabilidade dos adidos influencia as investigações de crimes, pelo incremento da disposição para compartilhar informações da contraparte e fomento a disponibilidade e qualidade destas. A abordagem qualitativa contribuiu para o aprofundamento da análise de percepção sobre a relação de confiabildiade e compartilhamento de informações, pois permitiu detalhamento e exemplificação de casos que subsidiaram a criação de categorias temáticas.

Introduction: There are international cooperation networks composed of public security institutions for the promotion, prevention and repression of transnational organized crimes, which need some factors to function properly. Goals: To analyze the perception of reliability of Federal Police attaches in sharing information with actors from similar international institutions, in support of crime investigations. Methods: The research is characterized as descriptive, transversal with a qualitative approach. By census sampling, virtual interviews were conducted with Federal Police attachés from 16 countries, with the support of a semi-structured script. Data were transcribed and submitted to content analysis, with some categories established a priori and others a posteriori. Results: The counterparty's reliability perception is only realized when the information is classified as sensitive, and is suppressed when the institution has a good reputation. The attache's physical presence was extremely important, especially in interactions with reliable actors from institutions whose reputation is negative. There was a variation in the analysis criteria for the perception of reliability adopted by the attachés referring to competence, integrity and benevolence, integrity being the criterion prioritized by the mode. Conclusions: The attachés' perception of reliability influences the investigation of crimes, by increasing the willingness to share counterpart information and promoting its availability and quality. The qualitative approach contributed to the deepening of the perception analysis on the relationship of reliability and information sharing, as it allowed detailing and examples of cases that supported the creation of thematic categories.

The objective was to determine the psychometric properties of the F-COPES in the Colombian population. Cross-sectional study, with 1373 people, aged between 18 and 84 years. Data were analyzed in Jasp, exploratory factor analyzes were performed using the weighted least squares estimation method and a promax-type oblique rotation. Confirmatory factor analyzes with diagonalized weighted least squares estimators and robust analysis methods. Internal consistency analysis using Cronbach's Alpha indices, McDonald's Omega, and the highest lower limit index. A structure of five factors was found, four original ones: finding social support, cognitive restructuring, finding spiritual support and passive evaluation, and a new one: neighbor support. The scale evaluates family functioning in crisis situations in the Colombian context. [ABSTRACT FROM AUTHOR]

The Generalized Problematic Internet Use Scale 2 was adapted for the adult population of Buenos Aires. Participants were 225 subjects (68.4% female; 30.7% male, 0.9% nonbinary). Instruments administered were: survey of sociodemographic data and characteristics of use of social networks; Generalized Problematic Internet Use Scale 2; Mental Health Continuum Short Form and; Symptom Check List-27. Confirmatory factor analysis was carried out; It was found an adequate fit of the structure proposed by the original author. Cronbach's and ordinals alphas ranged from .77 to .87. Significant positive correlations were found between the generalized problematic use of the Internet, the psychopathological symptoms and the time of use of social media. Associations were negative with psychological well-being. [ABSTRACT FROM AUTHOR]

Um procedimento comum na Engenharia de Confiabilidade é calcular a probabilidade de sobrevivência de um sistema em série. Utiliza-se esta formulação para calcular a confiabilidade de um equipamento com múltiplos modos de falha independentes. No entanto, perde-se a hipótese de independência entre os componentes do sistema quando se tem modos de falha correlacionados. Neste trabalho, foi utilizada uma distribuição de probabilidade bivariada, a distribuição de Gumbel, para calcular o custo de garantia de um produto sujeito a dois modos de falha não independentes. As funções densidade de probabilidade conjunta e de confiabilidade foram apresentadas e as equações de custo sob três diferentes políticas foram desenvolvidas a partir deste modelo. Um algoritmo foi desenvolvido para calcular o tempo médio para a falha supondo que a ocorrência de qualquer um dos modos de falha faça com que o cliente reivindique a garantia. Por fim, alguns exemplos numéricos e gráficos dos custos de diferentes políticas são apresentados.

Optimization is the act of obtaining the best possible result under established conditions. Usually, the optimization of a structural design is done considering the structure's dimensions, the materials' properties, and the loads as deterministic values. This way, the optimization process can lead to a more economical design without guaranteeing that this structure is safe. In practice, there are always uncertainties about the final dimensions of the built structure, material properties, and loads. Then, the need arises to use design optimization techniques based on reliability to guarantee a project that is both economical and safe. This objective is achieved by including uncertainties in the optimization process. This article evaluates the parameters that determine the global minimum of the optimization methods DDO (Deterministic Design Optimization) and RBDO (Reliability-Based Design Optimization). This work aims to compare the structural optimization methods of DDO and RBDO through an example. The results are obtained through the methods implemented in the Python language and show that when comparing the two optimization methods, the presence of uncertainties alters the optimal solution.

This study deals with the evaluation of the reliability index of prestressed girders members of road bridges in relation to the ultimate limit state (ULS) of bending failure. In a wide bibliographic review of scientific works that deal with structural reliability, prestressed structural elements and road bridges, it is observed that few of these deals specifically with the reliability of girders considering the codes NBR 7188 of 2013 and NBR 7187 of 2021. A mechanical model was developed for the calculation of the beam resistant moment and the Monte Carlo Method was used to obtain a data set that represents the statistics of the structure in the ULS. To obtain the reliability index - the first order reliability method (FORM) was used. The values obtained by the analytical method are validated using the Monte Carlo simulation method. For all evaluated cases, the value of the reliability index was higher than 4.0, which is higher than the minimum required value of 3.5, showing that the national normative recommendations for the design of beam members guarantee a very conservative level of safety.

Introduction: The Revised Self-Care Agency Rating Scale is an instrument designed to assess health self-care in clinical population. However, studies on its psychometric properties in the general non-clinical Colombian population are unknown. Objective: To validate the Revised Self-Care Agency Rating Scale with a sample of 306 volunteer participants in Colombia. Method: Psychometric methodological study carried out between October and December 2021. For the analysis of the validity of the structure, factorial, exploratory and confirmatory analysis techniques were applied. In a complementary way, the content validity was evaluated through a panel of experts. Finally, as evidence of the instrument's reliability, its internal consistency was analyzed using McDonald's Omega coefficient. Results: The findings show that the ASA-R shows a one-dimensional structure that explains 61.99 % of the total variance. The assessment of the relevance, clarity, precision and comprehension of the items had results that had an average that ranged from an Aiken's V between 0.79 and 0.99. The internal consistency showed a satisfactory index for the total scale (ω=0.93). Conclusions: The version of the ASA-R presented in this article has adequate metric properties and its use is recommended to measure health self-care agency in a healthy Colombian population.

Objective: The aim of this study was to perform a narrative review of the leading pediatric triage systems in emergency departments (EDs). Data source: Articles published between 1999 and 2019 were identified by searching the MEDLINE, EMBASE, and PubMed databases using the keywords “pediatric triage”, “pediatric assessment tools”, and “emergency department triage” with an emphasis on studies that evaluated the validation and reliability of triage systems. Data synthesis: A total of 105 articles on pediatric emergency triage systems in 12 countries were evaluated. Triage systems were divided into two groups: color-stratified triage systems and alert systems. The color-stratified triage systems included in this review were the Canadian Triage and Acuity Scale (CTAS), Manchester Triage System (MTS), Emergency Severity Index (ESI), and Australasian Triage Scale (ATS), and the alert systems included were the Paediatric Observation Priority Score (POPS), Pediatric Early Warning Score (PEWS), and Pediatric Approach Triangle (PAT). Evidence corroborates the validity and reliability of MTS, PaedCTAS, ESI version 4, PEWS, POPS, and PAT in pediatric emergency services. Conclusions: These are fundamental tools for risk classification of patients seeking treatment in EDs. Not all triage systems have been assessed for validity and reliability; nor are they well suited for all regions of the world. Employing triage systems in Brazil requires cultural adaptation and rigorous training of the local health staff, in addition to validation and reliability studies in our country, since the social and cultural context of this country differs from those where these tools were developed.

Este artigo propõe o desenvolvimento de um método para projetos de Dispositivos de Assistência Ventricular (DAV) que possa mensurar “in vitro” a melhoria da confiabilidade e riscos com conceito de segurança inerente, bem como critérios para a validação do projeto. Os modelos de DAV utilizados e desenvolvidos neste artigo de pesquisa foram: i) DAV.PETG-01 com um “design” superior e uma base que se conecta a estrutura da bomba, um acoplamento magnético com seis imãs que permite o acionamento por um motor externo e ajuste de folgas do eixo do mancal; ii) DAV.PETG.02 com um motor magnético “brushless”, rotor com mancais e elementos rolantes acionados por condução direta, que permite o funcionamento deste motor interno. O método, com o uso de análise de árvore de falhas, proporcionou a definição de frequência de falhas dos modelos testados que foram 5,0014E-02 para o DAV-PETG-01 e 3,314E-03 para o DAV.PETG.02. A frequência de falhas para as bombas da pesquisa de Reyes, utilizadas como referência para aplicação do método, foi 1,8228E-05. Com as frequências de falhas dos eventos topo para cada um dos modelos, foi possível calcular o índice de melhoria da confiabilidade entre eles, que foi de 0,068 e com uma % de Melhoria de Confiabilidade de 93,20%. Os modelos DAV.PETG.01 e DAV.PETG.02 foram plotados na região “inaceitável” do critério de aceitabilidade, em função da frequência de falhas elevada. Como referência as bombas de Reyes também foram plotadas, porém, na região “aceitável”. Para o problema de pesquisa, o método apresentou resultados mensuráveis da melhoria de confiabilidade, entre os modelos testados. Além de confirmar a aceitabilidade das bombas de Reyes, utilizado como estudo de caso. O critério de aceitabilidade mostrou-se coerente com os dados de confiabilidade calculados.

O presente trabalho teve como objetivo realizar uma análise de desempenho e confiabilidade de reatores UASB em 18 estações de tratamento de esgotos sanitários descentralizadas em escala plena. A confiabilidade foi avaliada por meio da metodologia desenvolvida por Niku et al. (1979) para os parâmetros DQO e SST. A verificação da forma da distribuição de frequência desses parâmetros consistiu de testes de aderência às distribuições Normal, Lognormal, Gama e Exponencial, por meio dos testes Qui-quadrado e Kolmogorov-Smirnov. Verificou-se que os dados de DQO e SST efluentes aos reatores UASB seguiu uma distribuição lognormal. De uma forma geral, o desempenho dos reatores no atendimento aos padrões de descarte para os parâmetros DQO e SST não foi satisfatório. Em uma análise conjunta dos coeficientes de confiabilidade, concentrações de projeto e percentuais esperados de atendimento constatou-se a pouca confiabilidade da maioria dos reatores em relação aos constituintes DQO e SST, sendo indicativo de sobrecargas orgânicas e hidráulicas, respectivamente.

Teaching thinking skills is a growing demand for educational systems due to its transversal role regarding competencies and learning and its functionality for persons and jobs in current knowledge societies. In psychological research, these skills are conceptualized as critical thinking, where teaching programs and some assessment tests, mainly aimed at adults, have been created. This study displays a culture-fair critical thinking assessment instrument, which addresses young people and includes figurative components, unlike other evaluation tools that are focused on specific learning. The instrument assesses four thinking skills, deduction, assumptions, sequences, and decision-making, and aims to students of secondary education (15-16 years). Its empirical validation considers students' school marks and the comparison between the participants' two grades, as external criteria, together with other procedures. The results show the psychometric characteristics of the assessment instrument for diagnosing students thinking skills; the most important findings are the significant and high correlations between school marks and thinking skills and the instrument discrimination for the differential diagnosis of two successive educational grades. Further, the validity and reliability of the figurative items are better than those of the verbal items, despite the latter being drawn from standardized instruments. Finally, the educational importance of creating a culture fair critical thinking assessment instrument and a common language that allows the development of the teaching thinking skills and their culture-free assessment within the classroom; further, some revision proposals for improving the instrument validity and reliability are suggested.

After trying to explain the meaning of the term reliability, the International Accounting Standards Board decided to replace it with another one that would more clearly show its meaning. For that reason, it proposed the term faithful representation. This fact caused unease among professional accountants, who pointed out that the Board could have better explained the meaning of reliability without replacing the term. This qualitative work aims to demonstrate the substantive differences between these terms etymologically. Among the most notable findings is that the Standards Council is aware that the term "faithful representation" may not work as an efficient filter for uncertainties and that the most notable tension arises between faithful representation and relevance.

Objetivou-se coletar evidências das propriedades psicométricas da Richmond Compulsive Buying Scale (rcbs) em estu-dantes universitários da Região Nordeste do Brasil. Para isso, foram realizados dois estudos. O Estudo 1 contou com 300 universitários oriundos do Nordeste brasileiro. Predominaram aqueles do sexo feminino (71 %), de universidade particular (67 %) e com média de idade de 23,5 anos (dp = 6,7). Os resultados indicaram uma estrutura empírica sustentável (teste de Kaiser-Meyer-Olkin [kmo] = 0,82), com indicadores psicométricos considerados adequados à mensuração da compra compulsiva. Além disso, uma estrutura unifatorial, constituída por seis itens, que explicaram 51,85 % da variância e alfa de Cronbach = 0,86. Já o Estudo 2 teve como finalidade testar a estrutura fatorial encontrada no Estudo 1. Participaram 279 universitários, a maioria de universidade pública (54,1 %), do sexo masculino (51,3 %) e com média de idade de 23,1 anos (dp = 4,74). Por meio da análise fatorial confirmatória, foram verificados bons indicadores de ajuste: X²/gl = 2,90; gfi = 0,98; cfi = 0,98; tli = 0,98; rmsea = 0,08 (ic 90 % = 04-0,10). Conclui-se que a rcbs apresentou parâmetros psicométricos adequados e é uma medida útil para os futuros estudos sobre a compra compulsiva.

A procrastinação faz os estudantes universitários adiarem e atrasarem seus trabalhos acadêmicos, ignorando suas responsabilidades acadêmicas durante todo o período de estudos. No entanto, ainda há poucas pesquisas sobre este assunto e poucos instrumentos validados para os brasileiros, com o objetivo de medir os níveis de procrastinação. O objetivo deste estudo é confirmar a estrutura fatorial da Escala de Procrastinação Acadêmica (EPA). Contou-se com 360 estudantes de graduação, a maioria de universidade privada (56,9%) e do sexo feminino (71,4%). Os resultados mostraram que a EPA possui duas subescalas: adiamento de atividades e autorregulação acadêmica. Esse modelo apresentou melhores índices de bondade, o que significa que na cultura brasileira os fatores subjacentes aos itens são os mesmos de outras culturas (e.g., Peru e Canadá). A análise dos dados por meio da Teoria de Resposta ao Item mostrou níveis de calibração dos itens significativos, isto é, os itens conseguem discriminar as pessoas, assim como apresentam níveis de dificuldade diferenciados para cada categoria de resposta do item. Logo, a estrutura bidimensional segue parâmetros estruturais significativos para adequação aos estudantes universitários brasileiros.

Introdução: As medidas antropométricas estão inevitavelmente associadas à erros de medida, sendo uma ferramenta que exige conhecimento e experiência por parte do avaliador. Objetivo: Determinar o erro técnico inter-avaliador entre três antropometristas inexperientes em jogadoras de futebol. Materiais e Métodos: Três antropometristas inexperientes avaliaram 17 jogadoras de futebol universitário com idade média de 22,4 ±3,1 anos, cada jogadora passou pelos procedimentos de aferição da massa corporal, altura, classificação do estado nutricional utilizando o í­ndice de massa corporal (IMC). A aferição de cada dobra e circunferência ocorreu de forma não consecutiva, sendo realizada três aferições para cada medida. As jogadoras foram divididas em dois grupos, sendo eutróficas e sobrepesadas a partir da classificação do IMC e os dados obtidos a partir das medidas foram utilizados para análise do Erro Técnico de Medida (ETM) inter-avaliador. Após a coleta, os dados foram tabulados e analisados através do programa Microsoft Excel 2019®. Resultados: Diante dos resultados, pode-se notar a presença de valores do ETM% relativo acima do considerado aceitável para todos os avaliadores e para diversas medidas de dobra cutânea e circunferências no grupo eutrofia e grupo sobrepeso. Conclusão: Os achados do presente estudo demonstram que, nas comparações entre os avaliadores, ocorreram diferenças nas medidas de avaliação, variando apenas a quantidade de medidas que ultrapassaram a variação estabelecida.

RESUMO A prematuridade é fator de risco para atraso do desenvolvimento motor, e recomenda-se o acompanhamento desses lactentes nos primeiros dois anos de vida. Verificar a confiabilidade intra e interexaminadores da Escala Motora Infantil de Alberta (EMIA) em ambulatório de seguimento de recém-nascidos de risco de uma maternidade pública. Estudo prospectivo realizado em ambulatório de seguimento de recém-nascidos de risco. As avaliações do desenvolvimento motor foram realizadas por meio da EMIA, por dois avaliadores previamente treinados. O Coeficiente de Correlação Intraclasse (CCI) foi utilizado para análise das confiabilidades. Para a comparação entre as avaliações intraexaminadores foi realizado o Teste T pareado ou Teste de Wilcoxon. O Teste T independente foi utilizado para comparar as avaliações interexaminadores. A correlação entre as variáveis foi analisada a partir do Teste de Pearson ou Spearman. Para avaliar a concordância entre os escores foi realizada análise de Bland Altman. Foram avaliados 31 recém-nascidos pré-termo (RNPT) com idade corrigida média de 8,47 ± 4,49. Não houve diferença significativa entre as avaliações intraexaminadores e interexaminadores. Os valores de CCI se mantiveram acima de 0,88 para a confiabilidade intraexaminadores e interexaminadores. Os escores apresentaram alta concordância, analisada por meio do teste de Bland Altman. EMIA apresentou adequada confiabilidade intra e interexaminadores para avaliação e acompanhamento de RNPT até 18 meses em ambulatório de seguimento de lactentes de risco.

A mais recente versão da teoria da confiabilidade tem sido utilizada para descrever a capacidade de um sistema de medição em detectar, identificar e remover outliers a um certo nível de probabilidade. Entretanto, as aplicações desta teoria têm sido direcionadas para redes simuladas de nivelamento. Aqui, por outro lado, aplicamos a teoria no contexto de redes baseadas nos sistemas de posicionamento por satélites GNSS (Global Navigation Satellite System), a partir de dados reais coletados em campo. Testamos se as covariâncias entre as componentes da linha base têm efeito sobre a confiabilidade. Verificamos que as covariâncias entre as componentes da linha base aumentam a taxa de sucesso na identificação de outlier e, portanto, aumentam a confiabilidade da rede. O menor outlier identificável – ao nível de 80% de correta identificação – teve uma redução média de ~30% para as componentes ΔX e ΔY, e ~14% para ΔZ em comparação ao cenário com covariâncias nulas. O aumento do nível de significância melhora a confiabilidade em ambos os cenários (covariâncias nulas e não-nulas) na mesma proporção. Porém, para altos níveis de significância (α > 0,1) e sistemas com boa redundância (ri > 0,5), a confiabilidade para um modelo estocástico com covariâncias nulas se aproxima do caso em que as covariâncias não são nulas. Na ausência de um modelo estocástico mais realista (covariâncias não-nulas) e para sistemas com boa redundância local (ri > 0,5), deve-optar por regiões críticas maiores ( k < 2,8).

The objective of this study is to analyze the validity evidence of the Academic Procrastination Scale (APS) in a sample consisting of 1979 students from public and private universities, from different courses, 67% of the students being women, aged 18 to 68 years old (M = 22.84). The principal component analysis revealed two components, also validated by confirmatory analysis, which showed a good overall fit of a two-dimensional model: Daily Study Procrastination (a = 0.75) and Exam Study Procrastination (a = 0.75). Internal consistency was estimated through Cronbach's alpha, obtaining 0.83 for the total scale. The study concludes that APS has satisfactory psychometric properties and suggests further validation studies and also analysis of academic procrastination in higher education students.
