Item type:Publication, Traducción, adaptación y validación del inventario de burnout de Copenhagen para Perú(Pontificia Universidad Católica del Perú, 2022-07-04)The goal is to adapt and analyze the psychometric properties of the Copenhagen Burnout Inventory (CBI) in workers of the national domestic violence helpline (Peru). Two measurements were taken in the same population (n=160). Translation-back translation was applied. Internal consistency was assessed with Cronbach’s alpha, corrected Item-Total Correlation and omega coefficient. Test-retest was performed in the second measurement. Convergent validity was examined with Pearson correlations with the Secondary Traumatic Stress Scale, the Perceived Stress Scale, and the Fear of Covid-19 Scale. Confirmatory Factor Analysis confirmed that the three-correlated factor model has the best fit. Regarding reliability, adequate coefficients were found (alpha: >.82, omega: >.91 and intraclass correlation: > .66). The CBI scales are correlated with the Secondary Traumatic Stress Scale, the Perceived Stress Scale, and the Fear of Covid-19 Scale, and they are also significantly associated with self-reported health status, but only work-related burnout is associated with self-reported workload. As a result, the CBI shows excellent psychometric properties. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Universality of the Triangular Theory of Love: Adaptation and Psychometric Properties of the Triangular Love Scale in 25 Countries(Taylor & Francis, 2020-08-12)The Triangular Theory of Love (measured with Sternberg's Triangular Love Scale - STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were based on a sample of 7332 participants from 25 countries (from all inhabited continents). We tested configural invariance, metric invariance, and scalar invariance, all of which confirmed the cultural universality of the theoretical construct of love analyzed in our study. We also observed that levels of love components differ depending on relationship duration, following the dynamics suggested in the Triangular Theory of Love. Supplementary files with all our data, including results on love intensity across different countries along with STLS versions adapted in a few dozen languages, will further enable more extensive research on the Triangular Theory of Love. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Enfoque Bayesiano en modelos de teoría de respuesta al ítem(Pontificia Universidad Católica del Perú. Departamento de Ciencias, 2010)El presente trabajo, es un documento desarrollado en el marco de la I Jornada Internacional de Probabilidad y Estadística, JIPE 2010. En este documento, se presenta los principales modelos TRI binarios unidimensionales a los que podemos denominar modelos TRI tradicionales. Estos modelos son denominados en la literatura como modelos de 1, 2 y 3 parámetros dependiendo de cuantos parámetros se asocian al comportamiento de los ítems o variables manifiestas e incluyen aquellos donde se emplea un enlace logit o probit entre la probabilidad de acertar un ítem y el predictor latente que contiene la variable latente y los parámetros de ítem. La propuesta es realizada desde la perspectiva de la Inferencia Bayesiana, corriente que ha tenido últimamente un gran desarrollo como consecuencia del uso de los denominados métodos MCMC (Markov Chain Monte Carlo, por sus siglas en inglés). Dado que los métodos MCMC son computacionalmente intensivos se ha querido también complementar la propuesta presentando los programas de software libre Bayes@PUCP y WinBUGS, el primero de los cuales está siendo, actualmente, desarrollado por los autores en el marco de un proyecto de investigación de la Dirección Académica de Investigación de la Pontificia Universidad Católica del Perú. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Fear of COVID-19 scale: adaptation and psychometric properties in Peruvian population(Spanish Society for the Study of Anxiety and Stress (SEAS), 2021-01-01)Context and Current context caused by COVID-19 has changed social and day-to-day life worldwide. Mental health is no exception. The objective of this study was to adapt and analyze the psychometric properties of the Fear of COVID-19 Scale (FCV-19S) in a sample of Peruvian professionals. Material and methods. The sample was composed of 169 participants of a longitudinal study about burnout during the pandemic in Peru. Translation-back translation method was performed (from English to Spanish). Confirmatory factor analysis (CFA) was conducted. Additionally, reliability analyses (Cronbach’s Alpha, McDonald’s Omega and Test-retest) and correlations with other variables were carried out. Results: Results confirm the one-dimensional nature of the instrument (CFA) with excellent indicators of goodness of fit (CFI =.996; TLI =.99; RMSEA =.06; SRMR =.04) and present good levels of reliability (α =.79; ω =.81; ICC =.75). Furthermore, evidence for external validity was found with the Secondary Traumatic Stress Scale and Perceived Stress Scale. The FCV-19S score presents previously unknown correlations with fear of infection of relatives, fear of infection in public places and self-reported perceived health. The score differs by gender, but further examination with larger samples are needed. Main conclusions: The Peruvian version of the FCV-19S shows solid psychometric properties. Its use is attractive for the study of mental health during the pandemic, and the design and focalization of initiatives in vulnerable groups and spaces - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Punto fijo en la medición psicológica: Limitaciones matemáticas en la psicología moderna(European Organization for Nuclear Research, 2025-09-19)La escala de medida ordinal, aunque es una de las más utilizadas y aceptadas dentro de la investigación psicológica, presenta limitaciones importantes que conducen a cuestionar su efectividad para el tratamiento cuantitativo de la realidad. La naturaleza de los fenómenos estudiados imposibilita establecer relaciones netamente numéricas dentro de la psicología. Ante esta realidad, la investigación analiza estas restricciones, centrándose en la ausencia del punto fijo de referencia, un concepto fundamental dentro de la matemática y la física, y que ha sido trasladado al campo de la psicología y cuya falta de datos ordinales, genera controversias. La metodología empleada es de tipo descriptiva y documental, basándose en un enfoque interdisciplinar. Entre los principales hallazgos se destaca que la ausencia del punto fijo de referencia genera tensiones entre los modelos cuantitativos, pues no culminan por comprender la amplitud de la subjetividad humana. Finalmente, se propone un cambio de paradigma, que provoque la visión complementaria, donde se articule lo axiomático con marcos interpretativos, considerando lo medible y lo no medible, elementos que, en conjunción, definen la naturaleza humana, haciendo de la medición un aspecto inclusivo, ético y plural.4
