El presente estudio tuvo como objetivos examinar la estructura interna de la versión en español del Inventario de Ansiedad ante Exámenes (TAI-E), y obtener una versión breve. Fue evaluada una muestra de 376 universitarios peruanos (73.1% mujeres) entre 16 y 55 años (M = 20.71). La estructura interna del TAI-E fue analizada mediante el modelamiento de ecuaciones estructurales (análisis factorial confirmatorio), y la versión breve fue obtenida teniendo como base un modelo Bifactor y criterios conceptuales. Fueron evaluados cuatro modelos: ortogonal, oblicuo, bifactor y unidimensional. En cuanto a los resultados, el TAI-E está constituido por una sola dimensión. Del mismo modo, la versión breve muestra indicadores robustos y evidencias de equivalencia empírica con la versión extensa. Finamente, las dos versiones mostraron coeficientes de confiabilidad con magnitudes elevadas. En...

Many instruments are created with the primary purpose of scaling individuals on a single trait. However psychological traits are often complex and contain domain specific manifestations. As such, many instruments produce data that are consistent with both unidimensional and multidimensional structures. Unfortunately, oftentimes, applied researchers make determinations about the final structure based solely on fit indices obtained from structural equation models. Given that fit indices generally favor the bifactor model over competing measurement models it is imperative that researchers make use of the available information the bifactor has to offer in order to compute informative indices including omega reliability coefficients, construct reliability, explained common variance, and percentage of uncontaminated correlations. Said indices provide unique information about the strength of bo...

El índice Dm tiene aplicaciones en psicometría, específicamente como una medida de validez de constructo de los ítems. En el presente trabajo se expone una aplicación alternativa del índice Dm para la comprobación de hipótesis generales en investigación empírica cuando esta involucra un constructo general y no es posible obtener una puntuación total para realizar dicho contraste. Para ello, es considerada la información de la comprobación de cada hipótesis específica, y sistematizada en Dm. Se ofrecen ejemplos para el caso de correlaciones y comparación de grupos. Entonces, la aplicación de Dm en el contexto de la comprobación de hipótesis generales es promisoria.

Introducción: La inclusión de correlaciones entre residuales en modelos de medición es una práctica común en la investigación psicométrica y está orientada, predominantemente, a la mejora estadística del modelo por medio del aumento (e.g., CFI) o disminución (e.g., RMSEA) de la magnitud de determinados índices de ajuste, más a que a comprender la naturaleza de dichas asociaciones. El presente reporte metodológico tiene como objetivo presentar al lector el modelamiento, manejo e interpretación de los residuales correlacionados en un marco de análisis factorial confirmatorio y malas especificaciones. Método: Se utilizando los datos de un estudio presentado anteriormente de 521 estudiantes de psicología en una universidad privada de Lima Metropolitana (75.8% mujeres). Se utiliza la Escala de Florecimiento para realizar los análisis. Resultados y Di...

The use of product-moment correlation of Pearson is common in most studies in factor analysis in psychology, but it is known that this statistic is only applicable when the variables related are in interval scale and normally distributed, and when are used in ordinal data may to produce a distorted correlation matrix . Thus is a suitable option using polychoric/tetrachoric matrices in item-level factor analysis when the items are in level measurement nominal or ordinal. The aim of this study was to show the differences in the KMO, Bartlett`s Test and Determinant of the Matrix, percentage of variance explained and factor loadings in depression trait scale of Depression Inventory Trait - State and the Neuroticism dimension of the short form of the Eysenck Personality Questionnaire -Revised, regarding the use of matrices polychoric/tetrachoric matrices and Pearson. These instruments was ana...

En el presente estudio se ha calculado la relación de la integración familiar y diversas variables socioeconómicas, entre los habitantes de Arequipa metropolitana. Para ello se ha hecho un muestreo probabilístico y se ha evaluado a 844 personas, jefes de hogar, mediante el Inventario de Integración Familiar (α= 0.739) y una ficha de recolección de datos. Los resultados señalan que existen relaciones positivas significativas pero bajas entre la integración familiar y los ingresos económicos, el grado de instrucción y el NSE. Además, el grado de instrucción superior, el estado civil casado y la religión evangélica predicen mejor la integración familiar.

The present article presents a program in MS Excel format for the calculation of the coefficient Ordinal Alpha and Armor Theta, used to quantify the reliability in ordinal response items. The construction of the commandos was made based on the polychoric correlation matrix of the program FACTOR (Lorenzo & Ferrando, 2007). The suitable use of these methods and their lack of implementation in traditional statistical packages justifies its construction like a tool for the investigator in psychology, discipline in which is common the use of Pearson correlation matrix with the limitations that this carries (it assumes that the studied variable is continuous). It is discussed the use and the limitations of the tool.

En los estudios cuyo objetivo es analizar las propiedades métricas de instrumentos de evaluación es deseable contar con evidencias de fiabilidad, entre las que destacan el análisis de la consistencia interna y el acuerdo entre observadores. Es habitual estimarlas a través del coeficiente alfa y k respectivamente. Ambos procedimientos fueron empleados por Orovigoicoechea y col, aunque sus resultados pudieron ser complementados con intervalos de confianza (IC) para alfa y k con el objetivo de brindar información adicional para su interpretación, ya que si bien es importante el estudio de la fiabilidad en toda investigación empírica, éste debe ser completo.

La valoración de la satisfacción del usuario puede brindar información útil tanto para optimizar los servicios brindados, como para realizar ajustes al mismo a fin de aumentar sus indicadores de aprobación. Por ello, un paso preliminar de suma importancia es la construcción de un instrumento que permita evaluar apropiadamente la satisfacción, es decir, que provea puntuaciones confiables y que estas permitan hacer inferencias válidas, tomando como base evidencias relacionadas con la validez.

Abstract The Cognitive Emotional Regulation Questionnaire (CERQ) was developed to assess cognitive emotional regulation strategies against unpleasant events. It was recently developed a short version (CERQ-18) in Peru and the results were favorable to assess their factorial equivalence regard to CERQ. The aim of this study was to analyze the relationship of CERQ-18 with external and internal criteria. In 286 college students aged 18 to 30 years old, was used a correlational analysis with measures of depression and anxiety. The results showed that the correlation pattern CERQ-18 and these measures was theoretically coherent, and also equivalent to the CERQ with these variables. The reliability of the dimensions of CERQ-18 was adequate, and estimate of the measurement error was similar to the long version. Finally, was conducted a statistical comparison between reliability coefficients of ...

The objective of the present study was to examine the internal structure of the Test anxiety inventory-State (TAI-State) in Spanish version. A sample of 125 college students from Lima (84.8% female) between 18 and 31 years old (M = 22.51) was evaluated. The internal structure of the STAI was analyzed by a confirmatory factor analysis, evaluating three models: oblique, bifactor and unidimensional. The results indicate that a single dimension constitutes the STAI and there are coefficients of reliability with high magnitudes. In conclusion, the version studied shows favorable psychometric properties that support its use in Lima.

The aim of this study was to create two short versions (15 and 10 items) of the Big Five Inventory (BFI) with empirical and theoretical bases. Participants included 332 Peruvian university students (82.83% women), aged between 16 and 48 years (M = 20.39). The main analysis was performed using the unweighted least squares method with oblique Procrustes rotation and fully specified matrix. The analysis results showed that both brief versions had robust psychometric properties: an adequate factor structure and empirical equivalence with the original BFI. Finally, the two versions displayed acceptable reliability indexes as well (αaverage > .60). In conclusion, both versions show favorable psychometric indicators that would enable their use in basic and group research.

Objectives: This paper aimed to analyze the internal structure of the Spanish version of the Ryff’s psychological wellbeing scale (PWBS-E) among college students (n = 1700, 54.75% females, Mage = 19.23) who attend a public institution located in Veracruz, Mexico. Method: The internal structure of the PWBS-E was assessed using the confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM) and exploratory factor analysis (EFA), while the reliability of the construct was estimated with the ù coefficient and the reliability of the scores, with the α coefficient. Results: suggested that a short and unidimensional structure (19 items) provides greater empirical support. In addition, a method factor associated with inverted items in multidimensional models was evidenced. Regarding the reliability, acceptable indicators were found in both levels (construct and scores...
