1. Longitudinal measurement invariance of neuropsychological tests in a diverse sample from the ELSA-Brasil study
Objective: Longitudinal measurement invariance analyses are an important way to assess a test’s ability to estimate the underlying construct over time, ensuring that cognitive scores across visits represent a similar underlying construct, and that changes in test performance are attributable to individual change in cognitive abilities. We aimed to evaluat

4. Gender invariance and psychometric properties of a Brazilian version of the Emotion Regulation Questionnaire (ERQ)
Abstract Introduction Emotion regulation refers to use of strategies to change or suppress a response to an affective experience and is an important component of an individual’s subjective wellbeing. Difficulties properly regulating emotions are related to psychopathological processes. Objective This study assessed the factor structure of the Brazilian

5. An Extension of the Invariance Principle for Switched Affine System
RESUMO Neste artigo, uma abordagem para investigar o sistema chaveado afim por meio de desigualdades matriciais é apresentado. Particularmente, uma extensão do princípio de invariância de LaSalle para esta classe de sistemas sob sinal chaveamento dwell-time arbitrário é apresentado. Os resultados propostos empregam uma função escalar auxiliar comum e

6. Factorial validity and measurement invariance of the uncertainty response scale
Abstract This study presents the adaptation of the Uncertainty Response Scale (Greco & Roger, Pers. Individ. Differ, 31:519-534, 2001) to Portuguese. This instrument was administered to a non-clinical community sample composed of 1596 students and professionals, allowing a thorough validity and invariance analysis by randomly dividing participants into three

7. Development and validity evidence of the multidimensional scale of sexual selfconcept in a Spanish-speaking context
Abstract Background/objective: STIs and HIV/AIDS are an important public health problem, transmitted by risky sex behaviours. In this context, it is necessary to identify protective factors, of those behaviours, as sexual self-concept. Sexual self-concept is a multidimensional trait (i.e. sexual self-esteem; sexual self-efficacy; and sexual assertiveness),

8. Dimensionalidade fractal e invariância de escala em circuitos elétricos AC e linhas de transmissão
Resumo A geometria fractal fascina pela capacidade de descrever formas geométricas complexas e que usualmente estão presentes no mundo real . A dimensão fractal ou de Hausdorff d é utilizada para descrever leis de invariância de escala, em que as funções autossimilares seguem uma lei da forma f ( s x ) = s d f ( x ), sendo s o fator de escala.

9. Scaling Symmetries and Conservation Laws for Variable-coefficients Nonlinear Dispersive Equations
RESUMO. Simetrias de escala surgem em diferentes ramos da física e abordagens baseadas em simetria são poderosas ferramentas para estudar modelos invariantes por escala, pois podem fornecer leis de conservação que não são óbvias por inspeção. Nessa perspectiva, a classe de equações dispersivas não-lineares com coeficientes variáveis vc K ( m ,

10. Bifactor Invariance Analysis of Student Conceptions of Assessment Inventory
Resumo As concepções de estudantes dos propósitos da avaliação são um aspecto importante da aprendizagem autorregulada. Este estudo avança nossa compreensão do Inventário de Concepções de Avaliação de Estudantes (CAE), pelo exame da generalização da estrutura fatorial do CAE usando análise bifatorial e realizando testes de invariância transc

11. Pain catastrophizing: rumination is a discriminating factor among individuals with different pain characteristic
Abstract: The objective of this study was to compare the scores of the Helplessness, Magnification, Rumination, and Catastrophizing factors of the Pain Catastrophizing Scale (PCS) between samples with different pain characteristics. The psychometric properties of the PCS were evaluated in 1,151 Brazilian adults (78.9% female; 38.6 (SD = 10.8) years): 335 had
