    Background: Validity evidence based on response processes was first introduced explicitly as a source of validity evidence in the latest edition of Standards for Educational and Psychological Testing. In this paper, we present the theory, the relationship with other sources of validity evidence, and the methods available for validation studies aimed at obtaining validity evidence about response processes. Method: A comprehensive review of the literature along with theoretical and practical proposals. Results: The articles provides arguments for determining when validity evidence based on response processes is critical for supporting the use of the test for a particular purpose, and examples of how to perform a validation study to obtain such validity evidence. Conclusions: There are methods for obtaining validity evidence based on response processes. Special attention should be paid to validation studies using the cognitive interview method given its features and possibilities. Future research problems pose how to combine data from different methods —qualitative and quantitative—, to develop complete validity arguments that support the use of the test for a particular purpose.Antecedentes: la evidencia de validez basadas en los procesos de respuestas fue incluida explícitamente por primera vez como fuente de evidencias de validez en la última edición de los Standards for Educational and Psychological Testing.

    In many Engineering applications the computation of improper integrals is a need. In [1] we pointed out the lack of some CAS when computing some types of improper integrals. Even more, the work developed showed that some improper integrals can not be computed with CAS using their build-in procedures. In this talk we will develop new rules to improve CAS capabilities in order to compute new improper integrals We will show some examples of improper integrals that CAS asMATHEMATICA, MAPLE, DERIVE or MAXIMA can not compute. Using advance techniques as Laplace and Fourier transforms or Residue Theorem in Complex Analysis, we will be able to develop new rules schemes for these improper integrals. We will also describe the conclusions obtained after using these new rules with our Engineering students when teaching Advanced Calculus. [1] José L.Galán-García, Gabriel Aguilera-Venegas, María Á.

    Ronald K. Hambleton: A Legacy Beyond Quantitative Scientific Indicators

    Get PDF
    Professor Ronald K. Hambleton (1943-2022) shaped the development of psychometrics in the United States and had a far-reaching impact on professionals interested in psychological and educational measurement worldwide. All three authors were at different times visiting researchers in the Research, Educational Measurement & Psychometrics (REMP) Program at the School of Education at the University of Massachusetts at Amherst (USA). We would like to develop these brief notes according to three main arguments of how Ron impacted our lives: Hambleton as a "professional model," Hambleton as an "educator," and the indelible imprint that Ron has left on our professional practice

    Measurement invariance of the driving inattention scale (ARDES) across 7 countries

    Get PDF
    The Attention-Related Driving Errors Scale (ARDES) is a self-report measure of individual differences in driving inattention. ARDES was originally developed in Spanish (Argentina), and later adapted to other countries and languages. Evidence supporting the reliability and validity of ARDES scores has been obtained in various different countries. However, no study has been conducted to specifically examine the measurement invariance of ARDES measures across countries, thus limiting their comparability. Can different language versions of ARDES provide comparable measures across countries with different traffic regulations and cultural norms? To what extent might cultural differences prevent researchers from making valid inferences based on ARDES measures? Using Alignment Analysis, the present study assessed the approximate invariance of ARDES measures in seven countries: Argentina (n = 603), Australia (n = 378), Brazil (n = 220), China (n = 308). Spain (n = 310), UK (n = 298), and USA (n = 278). The three-factor structure of ARDES scores (differentiating driving errors occurring at Navigation, Manoeuvring and Control levels) was used as the target theoretical model. A fixed alignment analysis was conducted to examine approximate measurement invariance. 12.3 % of the intercepts and 0.8 % of the item-factor loadings were identified as non-invariant, averaging 8.6 % of non-invariance. Despite substantial differences among the countries, sample recruitment or representativeness, study results support resorting to ARDES measures to make comparisons across the country samples. Thus, the range of cultures, laws and collision risk across these 7 countries provides a demanding assessment for a cultural-free inattention while-driving. The alignment analysis results suggest that ARDES measures reach near equivalence among the countries in the study. We hope this study will serve as a basis for future cross-cultural research on driving inattention using ARDES.Grant MCIN/AEI/ 10.13039/501100011033State Research Agency (SRA) (MCIN/AEI/) (PID2020-113978RB-I00 and PDC2021-12944-I00)Spain and European Regional Fund “ERDF” A way of making Europe"European Union” or by the “European Union NextGenerationEU/PRTR”Junta de Andalucía I + D + I Programa Operativo FEDER Andalucía (P20_00338, A-SEJ-114-UGR20 and PYC20 RE 022 UGR)Plan Nacional de Drogas (Ministerio de Sanidad) PND-020-019Funding for open access charge: Universidad de Granada / CBU

    Random samples generation with Stata from continuous and discrete distributions

    Simulations are nowadays a very important way of analyzing new improvements in different areas before the physical implementation, which may require hard resources which could only be affronted in case of a high probability of success. The use of random samples from different distributions are a must in simulations. In this talk we introduce new Stata functions for generating random samples from continuous and discrete distributions that are not considered in the defined Stata random-number generation functions. In addition, we will also introduce new Stata functions for generating random samples as an alternative of the build-in Stata functions. The goodness of the generated samples will be checked using the mean squared error (MSE) of the differences between the frequencies of the sample and the theoretical expected ones. We will also provide bar charts which will allow the user to compare graphically the sample with the exact distribution function of the random distribution which is being sampled.Universidad de Málaga.

The study aim was to explain attitudes justifying IPVAW identifying individual and societal risk factors. Design and setting A multilevel cross-sectional study of the World Values Survey (WVS) in 54 global countries. Participants A representative transnational community-based sample of 81 516 participants (47.8% male, 52.1% female), aged mean of 42.41. Measures Attitudes justifying IPVAW, sociodemographic, sexism, self-transcendence and conservation values were measured using questions from WVS. Country and regional gender inequality were assessed by Gender Inequality Index. Results Around 16% (intraclass correlation=0.16) of individual differences in attitudes justifying IPVAW are explained by countries. Statistically significant predictors at individual and country level were: sex (B=−0.24, 95% CI −0.27 to −0.22), age (B=−0.08 to −0.25, 95% CI −0.34 to −0.03), marital status (B=0.09 to 0.23, 95% CI 0.002 to 0.33), educational level (B=−0.10 to −0.14, 95% CI −0.20 to −0.04), self-transcendence values (B=−0.10, 95% CI −0.20 to −0.12), sexism (B=0.21, 95% CI 0.15 to 0.28), country (B=2.18, 95% CI 1.09 to 3.26) and regional (B=2.23, 95% CI 1.04 to 3.42) gender inequality. Country gender inequality (B=−0.18, p=0.12) and regional gender inequality (B=−0.21, p=0.10) did not moderate the associations between self-transcendence values and attitudes justifying IPVAW. In the same way for sexism, data did not provide support for a moderating role of country gender inequality (B=0.22, p=0.26) and regional gender inequality (B=0.10, p=0.66). Conclusions Individual and country predictors accounted for differences in attitudes justifying IPVAW. However, neither gender inequality of country nor gender inequality of region interacted with sexism and self-transcendence values. Theoretical and methodological implications are discussed.Scholarship for University Teachers Training - Spanish Ministry of Education, Culture and Sport FPU16/0302

    Revisión de las propiedades psicométricas de las versiones larga y reducida de la Escala sobre Ideología de Género

    Get PDF
    La ideología de género es un constructo de gran relevancia en el análisis psicológico del género, que se ha mostrado relacionado con multitud de comportamientos, creencias y actitudes de hombres y de mujeres, especialmente con aquellos relacionados con la discriminación de género. Tras definir el constructo que se pretende medir, en este estudio instrumental se revisan los estudios realizados para la elaboración y evaluación de las propiedades psicométricas de las versiones larga y reducida de la Escala de Ideología de Género (EIG). Los estudios revisados muestran que: a) los valores del coeficiente alfa para ambas versiones varían entre 0,70 y 0,90; b) el patrón general de las medias de las puntuaciones totales se inclina hacia el polo igualitario de la escala; y c) las evidencias convergentes y discriminantes de las mediciones aportadas por ambas versiones de la EIG son coherentes con la teoría sobre el constructo. Por último, se apuntan futuras investigaciones sobre la estructura factorial de las escalas y la utilidad predictiva del constructo ideología de género.Gender ideology is a very important construct in the psychological study of gender. Research has shown that gender ideology is related to many behaviours, believes, and attitudes of men and women, specially with those related to gender discrimination. Firstly, the construct ‘gender identity’ is defined. Secondly, in this article studies conducted to elaborate and evaluate the psychometric properties of the long and the short versions of the Gender Ideology Scale are revised. Results of these instrumental studies show the following: a) alpha coefficients for both versions range from.70 to .90; b) the general pattern of total scores is biased toward the equalitarian pole of the scale; and c) convergent and discriminant evidences related to the use of both versions are consistent with the theory about gender ideology. Finally, future research about the scale factorial structure and the predictive utility of the construct gender ideology are suggested.A ideologia de género é um construto de grande relevância na análise psicológica do género, que se tem mostrado relacionado com uma variedade de comportamentos, crenças e atitudes de homens e mulheres, especialmente com aqueles relacionados com a discriminação de género.

    The Psychological Consequences of COVID-19 and Lockdown in the Spanish Population: An Exploratory Sequential Design

    Get PDF
    The objectives of this study were to analyze the psychological impact of the COVID-19 pandemic and the lockdown in the Spanish population and to identify what population profiles were most affected. The study used a sequential exploratory design. In the qualitative phase, 40 participants were recruited based on theoretically relevant criteria and the saturation of the information provided by the interviews. In the quantitative phase, a large representative sample was applied. The universe considered was the adult population of Spain. A total of 6789 surveys were conducted. Both the analysis of the narratives of the interviews and the responses to the panel survey showed relevant changes in attitudes and mood swings compared to the period prior to lockdown. These changes include dysphoric moods (i.e., experiences of distress such as sadness/depression, anxiety, rage, feeling of unreality, worry, etc.) and also some euphoric moods (i.e., feelings of well-being, happiness, etc.). A higher number of women were affected than men and a greater increase was observed in younger people. The findings of the study may serve as a basis for detecting needs and providing psychological support, as the symptoms detected as the most common are key for the processes of screening at-risk individuals.Spanish Ministry of Universitie
