Invarianza factorial por sexo y puntos de corte del cuestionario de control de la imagen corporal en fotografías en población mexicana / Factorial invariance by sex and cut-off points of the body image control questionnaire in photographs in Mexican population

RESUMEN La imagen corporal varía a lo largo de la vida. Los cambios físicos que conlleva la adolescencia, pueden influir en el desarrollo de conductas de riesgo para trastornos alimentarios. Aunque los factores sociales y culturales afectan la imagen corporal, las formas de interacción modernas, mediante el uso de tecnología, en particular las redes sociales, permiten controlar la autopresentación de la imagen corporal en las fotografías que son publicadas, lo que podría servir como indicador de conductas de riesgo alimentarias. El objetivo de este trabajo fue establecer la asociación de conductas alimentarias de riesgo con el control de la imagen corporal en fotografías, para analizar su invarianza factorial por sexo y proponer puntos de corte en población mexicana. La muestra estuvo conformada por 1 155 adolescentes (51.3 % hombres y 48.7 % mujeres), con una media de edad de 15.18 años. Se utilizó el cuestionario en español sobre el control de la imagen corporal en fotografías denominado BICP-S, además del cuestionario de conductas alimentarias de riesgo (CAR). Los resultados evidenciaron una relación entre las conductas alimentarias de riesgo y el control de la imagen en fotografías. La estructura factorial del BICP-S varía en función del sexo, por lo que se proponen diferentes puntos de corte del cuestionario, en donde aquellas ubicadas en el percentil 85 indican riesgo acerca de las preocupaciones por la imagen corporal en mujeres, mientras que en hombres se establece en el percentil 92, con una alta confiabilidad en el control de la imagen en ambos sexos (α > 0.90). El cuestionario tiene utilidad clínica para la detección de jóvenes con serias preocupaciones en torno a la imagen corporal que, de continuar, pueden constituirse en un factor de riesgo para trastornos de la conducta alimentaria.

ABSTRACT Body varies throughout life. Physical changes that take place during teenage years may influence the development of risky behaviors related to eating disorders. Although social and cultural factors affect body image, modern forms of interaction with technology, particularly social networks, allow controlling the self-presentation of body image in the photographs that are published, which could serve as an indicator of risky eating behaviors. The aim of this study was to establish the association of risky eating behaviors with the body image control in photographies, to analyze the factorial invariance by sex and to propose cut-off points in the Mexican population. The sample consisted of 1 155 adolescents (51.3 % males and 48.7 % females), with a mean age of 15.18 years. The BICP-S was used, in addition to the risky eating behaviors questionnaire (CAR). The results showed a relationship between risky eating behaviors and image control in photographs. The factorial structure of the BICP-S varies according to sex, so different cut-off points of the questionnaire are proposed, where those located at the 85th percentile indicate risk about body image concerns in women, while in men it is established at the 92nd percentile, with a high reliability in image control in both groups (α > 0.90). It is concluded that the questionnaire has clinical utility for the detection of at-risk youth who may have serious body image concerns, which if continued can be a risk factor for eating disorders.

Evaluación de las propiedades psicométricas de la Escala de Curiosidad Epistémica de Litman en hispanohablantes

La Curiosidad Epistémica (CE) es el deseo que motiva a las personas a adquirir nuevo conocimiento. La escala de CE de Litman fue desarrollada para operacionalizar este constructo, y aunque su estructura latente ha sido validada en varios estudios, estos se han realizado en su mayoría en Alemania, EE. UU. y los Países Bajos, que son sociedades educadas, industrializadas, ricas y democráticas. Por consiguiente, el presente estudio evaluó las propiedades psicométricas de la escala de CE, en una muestra de adultos del noroeste de México (N = 334) con edades de 18 a 50 años. Al igual que en investigaciones previas, se compararon dos modelos: unidimensional y bidimensional, mediante análisis factoriales confirmatorios. Adicionalmente, se incluyeron los residuales correlacionados significativos, como parte de ambos modelos, y se examinó si el instrumento tiene invarianza de medición. Los resultados muestran que el modelo bifactorial presentó el mejor ajuste. La consistencia interna fue aceptable, y se comprobó que la escala posee invarianza configural, métrica, escalar y estricta. Usos potenciales de este constructo emergente incluyen su estudio como un factor motivacional relevante, en el nivel de involucramiento y las estrategias de formación de los estudiantes, así como su papel mediador en varios tipos de ansiedad en el aprendizaje.

Epistemic Curiosity (EC) is the desire that motivates people to acquire new knowledge. Litman's EC scale was developed to operationalize this construct, and although its latent structure has been validated in several studies, these have been conducted mostly in Germany, the Netherlands, and the United States, which are educated, industrialized, wealthy, and democratic societies. Therefore, the present study evaluated the psychometric properties of the EC scale in a sample of adults from northwestern Mexico (N = 334) aged 18 to 50 years. As in previous research, two models were compared: one unidimensional and one bidimensional, using Confirmatory Factor Analysis. Additionally, significantly correlated residuals were included as part of both models, and it was examined whether the instrument has measurement invariance. The results show that the bifactor model presented the best fit. The internal consistency was acceptable, and the scale was found to have configural, metric, scalar, and strict invariance. Potential uses of this emerging construct include its study as a relevant motivational factor in students' level of engagement and study strategies, as well as its mediating role in various types of learning anxiety.

Psychometric properties of the Entrepreneurial Intention Questionnaire (EIQ) in Dominican Republic adolescents

Introduction: This work represents the first attempt to obtain evidence of the validity of an entrepreneurial intention questionnaire in the adolescent population of a Latin American or Caribbean country. The objectives are to study the factor structure, the reliability, the external validity and to test the gender invariance of the Entrepreneurial Intention Questionnaire, in its adaptation for adolescents. Method: The sample consisted of 708 adolescents from the Dominican Republic with a mean age of 15.49, 65.2% of whom were women and 35.8% were men. Analyses included confirmatory factor analysis, Cronbach's Alpha and Omega scores for reliability, correlations, and a gender invariance routine. Finally, latent means of females and males are compared. Results: The confirmatory factor analysis showed a good fit to the data and the reliability results were adequate. In addition, the correlations with the Entrepreneurial Attitudes Scale for Students were positive and statistically significant. Also, strict gender invariance was successfully verified. Although males presented a higher subjective norm, females showed higher entrepreneurial intentions. Conclusions: The Entrepreneurial Intention Questionnaire shows adequate psychometric properties and proves useful in conducting research on the promotion of entrepreneurship in early stages.

Invarianza factorial del cuestionario How I Think en adolescentes peruanos según el sexo / Factorial invariance according to sex of the How I Think Questionnaire in Peruvian adolescents

Resumen Desde el surgimiento de la psicología cognitiva, las cogniciones han tomado gran relevancia para explicar una gran variedad de fenómenos psicológicos. Un constructo que ha sido empleado en el ámbito clínico y forense es el de las distorsiones cognitivas que tiene poder predictivo sobre la conducta violenta. Las distorsiones cognitivas se definen como cogniciones irracionales y negativas: pensamiento egocéntrico, culpar a los demás, minimización y asumir lo peor. Para evaluar las distorsiones cognitivas se ha empleado el cuestionario How I Think ("Cómo pienso"), que ha sido validado para población hispanoparlante, pero no contaba con una versión validada en Perú. La presente investigación tuvo como objetivo analizar las propiedades psicométricas de una prueba que evalúa las distorsiones cognitivas en una muestra de adolescentes de la ciudad de Arequipa, Perú. Se evaluó a 2803 estudiantes nivel secundario (48.9 % mujeres y 51.1 % varones) entre 13 y 19 años, a través del cuestionario How I Think de Barriga y Gibbs (1996). El procesamiento psicométrico implicó el análisis de la validez por medio del análisis factorial confirmatorio, la confiabilidad por el método de consistencia interna y la invarianza factorial según el sexo. Los resultados psicométricos indican que la prueba tiene validez de constructo con tres factores: culpar a los demás/asumir lo peor, la minimización y el egocentrismo. También tiene índices de confiabilidad adecuados y no presenta sesgos entre varones o mujeres. Se concluye que el cuestionario How I Think es un instrumento válido y confiable para evaluar a los adolescentes peruanos, aunque presenta variaciones con respecto a su estructura original.

Abstract Since the consolidation of the cognitive psychology and its diffusion around the world, the cognitions have taken a place of great relevance in order to explain a large variety of psychological events and phenomena. Nowadays the cognitive psychology is the dominant paradigm in the wide world of psychology, including obviously the Ibero-american countries. One construct that had been used in the field of clinical and forensic psychology is related to cognitive distortions, which have predictive power over the violent and aggressive behavior in children, adolescents, and adult people (Peña & Andreu, 2012). The cognitive distortions can be defined as a kind of negative and irrational cognitions (Ellis, 1999) that are used to explain or justify the aggressive behavior, and they are also linked to delinquent behavior (Roncero et al., 2016). Cognitive distortions can be classified in two types: self-serving and self-debasing cognitive distortions. In the first case, there are four types of self-serving cognitive distortions: Self-centered, Blaming others, Minimizing/Mislabeling, and Assuming the worst. In the second case, there are also four self-debasing cognitive distortions: Catastrophizing, Overgeneralizing, Personalizing, and Selective abstraction. Both types have great influence in people's beliefs, emotions, attitudes, and behaviors (Barriga et al., 2008). Several instruments have been applied to measure cognitive distortions. Some of them are orientated to measure the self-serving cognitive distortions and some others are orientated to measure the self-debasing type, such as The Cognitive Errors Questionnaire or The Automatic Thoughts Questionnaire. One of the most used tests to assess the self-serving cognitive distortions is the How I Think Questionnaire, that has been validated in Spanish-speaking population such as Spain, with adequate goodness of fit indexes and reliability; but there is not a validated version in Peru (Rojas et al., 2019). The present research pretends to analyze the psychometrical properties of the How I Think Questionnaire, a mental test that measures the cognitive distortions. Following that aim, this instrument was applied in a sample of adolescents from Arequipa (Peru), comprised of 2 803 middle and upper High School students (48.9 % female and 51.1 % male) between 13 and 19 years old. The version used of the How I Think Questionnaire was the one developed and validated by Barriga and Gibbs (1996), which has 54 items with five levels of Likert's scale response. The psychometrical process implies the analysis of validity by confirmatory factor analysis, reliability by the internal consistency method, and factorial invariance according to the sex of the adolescents that participated in the sample. The psychometrical results indicate that the How I Think Questionnaire possesses construct validity with three factors: Blaming others/Assuming the worst (which contains two factors from the original version), Minimizing and Self-Centered. It also has adequate reliability indexes, estimated by McDonald's Omega Test, and there are no trends to male or female scores according to the factorial invariance applied, taking sex as a comparison criterion. It is concluded that the How I Think Questionnaire is a valid and reliable instrument to assess Peruvian adolescents who live in Arequipa, although it presents some variations compared to its original structure. And the How I Think Questionnaire can be applied in male and female adolescents from Arequipa without the risk of biased scores. However, it is recommendable to perform new psychometric studies that include adolescent's samples from all of Peru to obtain a standardized version for the Peruvian population that could be used in several fields of psychological work. The version presented in this research is a useful instrument to assess cognitive distortions in educational, social, and forensic psychology, by mental health specialists in Arequipa Metropolitan City.

Escala de Percepción de Reforzamiento Medioambiental (EROS): evidencias de validez en una muestra colombiana

Introducción: El objetivo de esta investigación fue confirmar la estructura interna de la Environmental Reward Observation Scale (EROS) y recoger evidencias de su relación con otros constructos en una muestra colombiana de 902 adultos que consintieron participar voluntariamente. Método: Se realizaron análisis psicométricos con Teoría Clásica de los Test y el modelo de Rasch. Se recolectaron evidencias de validez de la estructura interna y de la relación de las puntuaciones con otras variables. Resultados: Se obtuvieron buenos índices en los coeficientes alfa y omega de McDonald, nueve de los 10 ítems tuvieron buenos ajustes en los índices infit y outfit, y el ítem ocho presentó DIF en el nivel educativo. Se confirmó la estructura unidimensional de la EROS y fue invariante respecto al sexo y nivel educativo. Los puntajes tuvieron correlaciones de magnitud alta con sintomatología emocional y variables afines a la Activación Conductual. Conclusiones: La EROS presentó altas calidades psicométricas para su uso en población colombiana; sin embargo, se recomienda su uso solo para evaluación de tamizaje, porque los niveles de información están centrados en un área reducida a lo largo de la métrica logit.

Introduction: The aim of this research was to confirm the internal structure of the Environmental Reward Observation Scale (EROS) and to collect evidence of its relationship with other constructs in a Colombian sample of 902 adults who voluntarily consented to participate. Method: Psychometric analyses were performed using Classical Test Theory and the Rasch model. Evidence of validity based on internal structure and relations of scores with other variables was collected. Results: Good indexes were obtained in McDonald's Alpha and Omega coefficients, 9 of the 10 items had good adjustments in the Infit and Outfit indexes, and item 8 presented DIF in the educational level. The unidimensional structure of the EROS was confirmed and was invariant with respect to sex and educational level. Scores had high magnitude correlations with emotional symptomatology and variables related to Behavioral Activation. Conclusions: The EROS presented high psychometric qualities for its use in the Colombian population; however, its use is recommended only for screening assessment because the levels of information are centered in a reduced area along the Logit scaling.

Invarianza factorial de dos versiones breves de la Escala de Resiliencia de Connor-Davidson (CD-RISC) en estudiantes universitarios de Arequipa / Factorial Invariance of two Short Versions of the Connor-Davidson Resilience Scale (CD-RISC) in Arequipa University Students

Resumen La resiliencia es una característica individual que posibilita el reajuste biopsicosocial y espiritual que ayuda al bienestar psicológico y al desenvolvimiento académico de los estudiantes universitarios. El objetivo de esta investigación fue analizar la invarianza de medición según el sexo, de dos versiones breves de la Escala de Resiliencia de Connor-Davidson (CD-RISC) y determinar si existen diferencias entre hombres y mujeres. Se evaluó con la CD-RISC-10, que incluye la CD-RISC-7, a una muestra de 491 universitarios arequipeños (312 mujeres; 179 hombres) con edad promedio de 20.56 años (DE = 3.18), de una institución privada. Inicialmente se realizó un análisis factorial multigrupo con cada versión para valorar el grado de invarianza de medición alcanzado, y luego de ello se compararon las medias latentes de resiliencia entre hombres y mujeres. En cuanto a los resultados, la CD-RISC-7 presentó indicadores estructurales más favorables (e.g., λ > .50; en mujeres: CFI = .981, RMSEA = .087, WRMR = 0.683; en hombres: CFI = .966, RMSEA = .124, WRMR = 0.783), que la CD-RISC-10 (e.g., λ < .50, índices de ajuste en mujeres: CFI = .974, RMSEA = .073, WRMR = 0.774; en hombres: CFI = .960, RMSEA = .095, WRMR = 0.803) incluyendo la invarianza de medición (invarianza estricta: ΔCFI = .003; ARMSEA = .001), y al comparar las medias latentes fueron halladas diferencias significativas a favor de los hombres (d = .471). Finalmente, se discuten las implicancias teóricas y metodológicas de los hallazgos, así como la necesidad de ampliar los estudios considerando otros aspectos relevantes para una mejor comprensión del constructo resiliencia.

Abstract Resilience is an individual trait that enables biopsychosocial and spiritual readjustment, helping the psychological well-being and academic performance of university students. The objective of this research was to analyze the measurement invariance by sex of two short versions of the Connor - Davidson Resilience Scale (CD-RISC), and to determine if there are differences between men and women. A sample of 491 Arequipa university students (63.5% women), with an average age of 20.56 years-old (SD = 3.18), from a private institution in Arequipa-Peru was evaluated with the CD-RISC-10, which includes the CD-RISC-7. First, a multi-group factor analysis was carried out with each version to assess the degree of measurement invariance achieved, and then the latent means of resilience between men and women were compared. Regarding the results, the cD-Risc-7 presented more favorable structural indicators (e.g., λ > .50; in women: CFI= .981, RMSEA= .087, WRMR = 0.683; in men: CFI= .966, RMSEA= .124, WRMR= 0.783), than THE CD-RISC-10 (e.g., λ < .50, fit indices in women: CFI = .974, RMSEA = .073, WRMR = 0.774; in men: CFI = .960, RMSEA = .095, WRMR = 0.803), including measurement invariance (strict invariance: ΔCFI= .003; ARMSEA = .001), and when comparing latent means, significant differences in favor of men were found (d = .471). Finally, the theoretical and methodological implications of the findings are discussed, as well as the need to extend the studies considering other relevant aspects for a better understanding of the resilience construct.

Psychometric properties of the Insomnia Severity Index (ISI) in Mexican adults / Propiedades psicométricas del Índice de Severidad de Insomnio (ISI) en adultos mexicanos

Background: Insomnia is the sleep disorder with the highest incidence worldwide. It is estimated that this condition increases the risk of developing psychiatric, neurological, and cardiovascular problems. Due to this, it is important to have brief, reliable and valid psychometric instruments that allow health personnel their timely detection in first level health centers. Objectives: Analyze the psychometric properties of the Insomnia Severity Index (ISI) in its version adapted to Spanish in a sample of Mexican adults. Methods: The sample consisted of 310 adults, 223 (71.9%) women and 87 (28.1%) men. The comparison of four ISI measurement models of one, two and three factors and a bifactor model was carried out, its internal consistency was analyzed, an analysis of invariance by sex and correlation analysis with the Athens and Epworth scales. Results: The ISI bifactor model with a general factor (G) and a specific factor for insomnia impact (I) showed the best fit indices (χ2= 29.48, gl = 11, SRMR= 0.03, CFI= 0.98, TLI= 0.96, RMSEA= 0.07), and demonstrated configural, metric, and scalar invariance by sex. Adequate reliability was demonstrated by Omega coefficients (General: ωG= 0.86, Impact: ωI= 0.86) showed adequate reliability; the scale showed very strong correlations with the Athens scale (rAGoverall= 0.84; rAImpact=0.75) and weak to moderate correlations with the Epworth scale (rEGeneral= 0.39; rEImpact=0.44). Conclusions: The ISI bifactor version in Spanish presents adequate psychometric properties for the measurement of insomnia and, as it is a brief tool, it can be used at different levels of health care.

Reliability and validity of the 6-item UCLA Loneliness Scale(ULS-6)for application in adults / 南方医科大学学报

OBJECTIVE@#To evaluate the psychometric properties and applicability of the 6-item University of California Los Angeles (UCLA) Loneliness Scale (ULS-6) in adults.@*METHODS@#We conducted 2 surveys to assess the validity of different measurement scales and questionnaires. In Survey 1, a total of 1480 adults were measured using the UCLA Loneliness Scale (ULS), Patient Health Questionnaire-9 (PHQ-9) and Perceived Social Support Scale (PSSS), and the data were used for item analysis and assessment of the reliability, validity and measurement invariance. In Survey 2, UCLA Loneliness Scale was used for measurement in 652 college students, and the data were used for analysis of the criterion validity of ULS-6; 3 weeks later, 300 of the students were retested using ULS-6 to assess the retest reliability of the scale.@*RESULTS@#Item analysis suggested that the items in ULS-6 all had good discrimination power with discrimination indexes all above 0.775 (r=0.775-0.820, P < 0.001). Measuring only one dimension, ULS-6 had an internal consistency reliability of 0.891, a split-half reliability of 0.875, and a retest reliability of 0.726. The correlation coefficients of ULS-6 with ULS, ULS-8, PHQ-9 and PSSS were 0.882, 0.967, 0.528 and -0.532, respectively. The measurement invariances of ULS-6 across genders and age groups were all acceptable. Among the adult participants, the mean total score of ULS-6 was 12.97 ± 3.96; While only 20% of the adults had no loneliness, 80% of them exhibited varying degrees of loneliness, ranging from mild (39.6%) and moderate (25.7%) to intense (14.7%) feelings of loneliness.@*CONCLUSION@#The ULS-6 has good reliability, validity and applicability for measurement of loneliness in Chinese adults.

Cross-cultural invariance of the Spanish version of the COVID-19 Assessment Scorecard to measure the perception of government actions against COVID-19 in Latin America

Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID--19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

Avaliação psicológica e avaliação da aprendizagem em larga escala: diretrizes para pesquisadores / Large-scale psychological assessments and learning assessments: guidelines for researchers / Evaluación psicológica y evaluación del aprendizaje a gran escala: directrices para investigadores

A avaliação psicológica (AP) e a avaliação educacional (AE) estão entre as contribuições mais importantes das ciências cognitivas e comportamentais para a sociedade atual, pois proporcionam importantes fontes de informações sobre os indivíduos e os grupos. O presente artigo objetivou apresentar diretrizes para os pesquisadores em relação a AP e a avaliação da aprendizagem em larga escala (AALEs). São discutidos os caminhos da AP em um mundo em crise sanitária devido a pandemia da Covid-19. Em termos das AALEs, são discutidos aspectos teóricos, metodológicos e analíticos que devem ser considerados pelos avaliadores e pesquisadores da área. Concluímos que a AP e AALE se relacionam na medida em que ambas cumprem a função social de identificar lacunas que merecem atenção, bem como aspectos funcionais que devem ser mantidos e incentivados. Outra importante característica é a exigência de constante aprimoramento técnico por parte dos avaliadores e pesquisadores. (AU)

Psychological assessment (PA) and educational assessment (EA) are among the most important contributions of cognitive and behavioral sciences to modern society. They provide important information about individuals and groups that are a part of the society. The aim of this article is to present guidelines for researchers regarding PA and large-scale learning assessments (LSLAs). The paths of PA in a world in health crisis due to the Covid-19 pandemic are discussed. In the context of LSLAs, we discuss theoretical, methodological and analytical aspects that must be considered by evaluators and researchers in the area. We conclude that PA and LSLAs are related to the extent that both fulfill the social function of identifying gaps that deserve attention, as well as functional aspects that must be maintained and encouraged. Another important characteristic is the requirement for constant technical improvement by both evaluators and researchers.(AU)

Background Based on the theory by Carver y Scheier, optimism is defined as a trait or disposition consisting of two dimensions, optimism and pessimism. This construct is widely studied for its association with quality of life and psychological well-being. In the Chilean context, this construct does not have a valid measure of children and youth. This paper offers, is offered an alternative for its evaluation in a wide range of ages through the measurement carried out by the fathers and mothers. Objective For the analysis, reliability was reviewed for the total sample, by gender of parents, and by age group. Likewise, for confirmatory factor analysis, the adjustment indices commonly used in research practice were reviewed. This study aims to assess the factor structure of LOT-P on Chilean children and youth, as reported by parents. Results Data obtained on a sample of 392 Chilean parents show a good fit with the two-dimensional structure proposed by Lemola et al. Additionally, results show metric invariance between mothers and fathers, s for different age types. Conclusions Therefore, LOT-P shows psychometric properties suitable for assessing NNA optimism, as reported by parents. This investigation has some limitations related with a high educational and socioeconomic level of the participants, for example.

Estructura factorial y datos normativos del Inventario de Depresión de Beck (BDI-II) en población general peruana / Factor structure and normative data of the Beck Depression Inventory (BDI-II) in the general Peruvian population

Resumen El objetivo principal de este estudio fue analizar la dimensionalidad del BDI-II, así como demostrar la invarianza según el sexo y construir datos normativos en población general peruana. Para ello, se contó con la participación de 1665 personas (51.83 % mujeres) procedentes de diferentes regiones del Perú (75.92 % de Cajamarca, 11.05 % de Lima, 6.42 % de La Libertad y 2.62 % de Lambayeque), con un rango de edad de 18 a 54 años (M = 24.99; DE = 8.73), a quienes se les administró el BDI-II. Mediante un análisis factorial confirmatorio se probaron catorce modelos basados en estudios previos. Los resultados indicaron que los modelos bifactor y de segundo orden tenían problemas de convergencia, mientras que los bidimensionales y el unifactorial presentaban adecuados índices de ajuste. Se seleccionó el modelo unidimensional debido a su coherencia teórica, pues los creadores del BDI-II señalan que la prueba se debe interpretar de manera global, sumando los 21 ítems, y desaconsejan la interpretación mediante el cálculo de puntajes separados por dimensiones. Incluso, los antecedentes indican que la varianza explicada del segundo factor es muy baja, por lo cual dicha práctica estaría injustificada. Además, los estudios previos han señalado correlaciones interfactoriales muy altas. Finalmente, se demostró invarianza según el sexo, y los datos normativos, calculados mediante percentiles, mostraron que las puntuaciones superiores a 11 serían clínicamente relevantes. En conclusión, el BDI-II muestra buenas propiedades psicométricas en una estructura unidimensional con 21 ítems, la cual es invariante según el sexo y tiene datos normativos adecuados para población general peruana.

Abstract The aim of this study was to analyze the dimensionality of BDI-II, as well as to demonstrate gender invariance and construct normative data in the general Peruvian population. For this purpose, the BDI-II was administered to 1665 participants (51.83% women) from different cities of Peru (75.92% from Cajamarca, 11.05% from Lima, 6.42% from La Libertad and 2.62% from Lambayeque), with an age range of 18 to 54 years (M = 24.99; SD = 8.73). Fourteen models, based on previous studies, were tested by confirmatory factor analysis. The results indicated that the bifactor and second-order models had convergence problems, whereas the two-dimensional and unifactor models had adequate goodness-of-fit indices. The unidimensional model was selected due to its theoretical coherence, since the BDI-II creators point out that the test should be interpreted globally by adding the 21 items, and discourage interpretations by calculating scores separated by dimensions. Furthermore, the antecedents indicate that the variance explained by the second factor is very low. Therefore, this approach would be unjustified. In addition, previous studies have indicated very high interfactor correlations. Finally, gender invariance was demonstrated, and normative data were calculated using percentiles, indicating that scores above 11 would be clinically relevant. In conclusion, the BDI-II has good psychometric properties in a unidimensional structure with 21 items, which is sex invariant and has adequate normative data for the general Peruvian population.

Prosocial Tendencies Measure Validation for Portuguese Late Adolescents

O Questionário de Tendências Prossociais (MTP) de Carlo e Randall (2002) é amplamente usado para avaliar tendências prossociais. Partindo do pressuposto de que existem diferenças no comportamento pró-social entre adolescentes e adultos, o presente estudo teve como objetivo validar a versão em português do MTP com uma amostra de adolescentes. Este instrumento avalia seis tipos diferentes de tendências prossociais: altruísta, anónima, emergência, emocional, complacente e pública. Desenhado para confirmar esta estrutura fatorial do MTP com adolescentes portugueses, este estudo recolheu as perceções de um total de 1313 adolescentes a frequentar o ensino secundário. A análise fatorial confirmatória corroborou a estrutura de seis fatores da validação original. Além disso, considerando o ano escolar e o género dos alunos, a análise de invariância foi executada e atestou a invariância configural, métrica (parcialmente para género) e escalar (parcialmente para ano escolar e género) do MTP. Estes resultados demonstram ainda que a versão portuguesa MTP é confiável, aumentando a utilidade deste instrumento para avaliar comportamentos prossociais na adolescência.

The Prosocial Tendencies Measure (PTM; Carlo & Randall, 2002) is widely used for assessing prosocial tendencies. Assuming that there are differences in prosocial behavior between adolescents and adults, the current study aimed to further validate the Portuguese version of the PTM for adolescents. This instrument assesses six different types of prosocial tendencies ­ altruism, anonymous, dire, emotional, compliant and public. Designed to confirm this structure with Portuguese adolescents, this study collected a total of 1313 high school students' prosocial behaviors perceptions. Confirmatory factor analysis corroborated the six-factor structure of the original validation. Furthermore, considering the students' school year and gender, invariance analysis was executed and attested the PTM's configural, metric (partially for gender) and scalar (partially for school year and gender) invariance. These findings further demonstrate that the Portuguese version of the PTM is reliable, enhancing the utility of this instrument to assess prosocial behaviors in adolescence.

Propriedades Psicométricas da Frost Multidimensional Perfectionism Scale para adultos brasileiros / Propiedades psicométricas da Frost Multidimensional Perfectionism Scale para adultos brasileños / Psychometric properties of the Frost Multidimensional Perfectionism Scale for Brazilian adults

O objetivo do presente estudo foi investigar a estrutura interna da Frost Multidimensional Perfectionism Scale (FMPS) para adultos brasileiros, além de averiguar também a sua confiabilidade e estabilidade temporal. Participaram 1.222 indivíduos, com média de idade 26,57 anos (dp = 9,03), sendo que 618 participaram presencialmente e 604 por meio de coleta online. A escala foi reaplicada em 10% da amostra do grupo presencial para avaliar estabilidade temporal. Os resultados da análise fatorial confirmatória apontam que o modelo de seis dimensões, conforme proposta original dos autores da escala, apresentou os melhores índices de ajuste. A estrutura interna avaliada para os dois formatos de aplicação apresentou invariância estrutural, métrica e de configuração limítrofe, apontando para necessidade de ser mais bem investigada em estudos futuros. Tanto os índices de consistência interna quanto a estabilidade temporal são satisfatórios e corroboram os demais achados da literatura com a escala para outros idiomas. Conclui-se que a FMPS possui adequada validade de estrutura interna e confiabilidade para uso no Brasil.(AU)

The aim of this study was to examine the internal structure, reliability, and temporal stability of the Frost Multidimensional Perfectionism Scale (FMPS) for Brazilian adults. The sample included 1222 participants, with a mean age of 26.57 years (SD=9.03). Half of the sample completed the online version of the instrument, while the other half answered the paper-and-pencil version. To check temporal stability, the instrument was reapplied with 10% of the presential sample. The results from the confirmatory factorial analysis indicated that the original six-dimension model was the best fit for the scale. The internal structure evaluated for the two application formats showed only borderline structural, metric and configuration invariance, highlighting the need for future studies. Both the internal consistency and the temporal stability indices were satisfactory and corroborate the literature findings for the scale in other languages. In conclusion, the FMPS has adequate structural validity and reliability for use in the Brazilian context.(AU)

Validez de la Estructura Interna del Utrecht Work Engagement Scale (UWES) en trabajadores peruanos / Internal structure validity of Utrecht Work Engagement Scale (UWES) in Peruvian workers

Resumen El Utrecht Work Engagement Scale (UWES), medida de engagement laboral, ha tenido controversias respecto a la interpretación de su dimensionalidad, es decir, si sus puntajes pueden ser unidimensionales, multidimensionales o de dos niveles (unidimensional y multidimensional). El presente estudio tuvo por objetivo examinar la estructura interna (dimensionalidad, invarianza de medición y confiabilidad) del UWES (dos versiones: larga y breve) en una muestra de 636 trabajadores peruanos. Se aplicó el modelamiento de ecuaciones estructurales para la evaluación de tres modelos de dimensionalidad: un solo factor (unidimensionalidad), tres factores relacionados (multidimensionalidad) y bifactor (dos niveles de interpretación: factor general y factores específicos). Los resultados indican que, luego de aplicar el modelamiento bifactor, la varianza común obtenida de un factor general es más fuerte que la interpretación de tres dimensiones. Este resultado se repitió en ambas versiones del UWES (larga y breve). La invarianza de medición fue satisfactoria en el nivel configuracional, métrica y escalar (en ambas versiones). Con respecto a la consistencia interna, se obtuvieron coeficientes satisfactorios (mayores a .70). Se concluye que el modelo de tres dimensiones del UWES para obtener los puntajes debe ser reemplazado por un modelo unidimensional, representado con un puntaje total. Se discuten las implicaciones teóricas y prácticas.

Abstract The Utrecht Work Engagement Scale (UWES), a measure of work engagement, has had controversies regarding the interpretation of its dimensionality, that is, whether its scores can be one-dimensional, multidimensional or two-level (one-dimensional and multidimensional). The dimensionality of the UWES has been questioned mainly due to the high covariation between its components, an aspect consistently verified in the observed scores and latent variables (De Bruin y Henn 2013), even by the same authors (Schaufeli et al., 2006). This has two implications, one operational and one conceptual. In the operational context, the calculation of scores is also influenced by the statistical differentiation of the factors found in the factor analyzes. This means that if one or more factors are retained and justified, this also determines the same number of observed scores that can be calculated and interpreted. On the other hand, the conceptual implication is that the comprehensive framework of a three-dimensional psychological phenomenon differs from the one-dimensional. For example, the differentiation between dimensions generates the possibility of different trends between dimensions (e. g., one of three is high and the other low) and in this case, the concept of engagement becomes very generic and ambiguous to name and understand the different possibilities. Specific combination of its dimensions or jeopardizes its content validity, implying the need for other more specific concepts, which although related to engagement, can be independent. The objective of the present study was to examine the internal structure (dimensionality, measurement invariance and reliability) of the UWES (two versions: long and short) in a sample of 636 Peruvian workers. Structural equation modeling was applied to evaluate three dimensionality models: a single factor (one-dimensionality), three related factors (multidimensionality) and bifactor (two levels of interpretation: general factor and specific factors). The results indicate that, after applying bifactor modeling, the common variance obtained from a general factor is stronger than the three-dimensional interpretation. This result was repeated in both versions of the UWES (long and short). The measurement invariance was satisfactory at the configurational, metric and scalar levels (in both versions). Regarding internal consistency, satisfactory coefficients (greater than .70) were obtained. Three issues emerge from this study that modify the original theoretical interpretation of the UWES (which consists of using three related factors). The first is the existence of a general factor underlying the items, and which is statistically substantial as a source of variance of the items, independent of specific factors. In this general factor, the items generally contribute to their variance, except for two items whose discriminative capacity is moderately low (11 and 13, both of the specific factor Absorption). The main element of this general factor is the Dedication factor, whose items completely represented this general factor. Second, the differentiation of two specific factors corresponding to Vigor and Absorption does not appear to be psychometrically sufficient to describe nested constructs within the engagement construct, and therefore its independent interpretation of the general factor could be questioned. However, a contrary argument is that both factors show different amount of specific variance, although low compared to the general factor; for example, Absorption shows more divergent validity compared to Vigor, while the latter contains more common variance (general factor). Third, Dedication was completely absorbed by the general factor, and is only relevant insofar as its items are completely related to the general factor. Therefore, this component lost statistical autonomy and, consequently, very poor conceptual differentiation. It is concluded that the UWES - three-dimensional model to obtain the scores must be replaced by a one-dimensional model, represented with a total score. Implications are future research are discussed.
