Background: The overall aim of the study was to translate into Spanish and evaluate the psychometric properties of the Coronavirus Anxiety Scale (CAS). Method: The sample was composed of 622 Peruvian young people and adults who answered CAS. The structural evaluation was conducted with confirmatory factor analysis. Factorial invariance was used to verify the equivalence by sex and age. Results: The unifactorial model revealed good fit indexes χ²(5) = 12.40, CFI = .998, TLI = .996, RMSEA = .049, SRMR = .033.  Also, the internal consistency using McDonald´s Omega coefficient was high (ω > .80). The factorial invariance indicated that the unifactorial structure is stable according to age. Conclusion: The Peruvian version of the CAS has evidence to be considered an accurate, valid, and invariant measure and the results support the unifactorial model.

The psychometric properties of the General Anxiety Disorder-7 (GAD-7) and its ultra-short versions, the GAD-2 and the GAD-Mini, were evaluated in a sample of 407 students from two Peruvian universities (259 females and 148 males). First, a structural analysis was performed using the CFA, showing a good fit with respect to the instrument's unifactorial model χ²(14) = 31.717, CFI = .995, TLI = .992, RMSEA = .056, SRMR = .026. In addition, a measurement invariance analysis was performed, finding a stable unifactorial structure considering sex. Furthermore, evidence of convergent validity was analyzed in the GAD-7 and its ultra-short versions, presenting moderate correlations with instruments such as the PHQ-2 and the AAQ-II. The internal consistency of the instruments was evaluated using the omega coefficient and obtained high values of .89, .80, and .79 in the GAD-7, GAD-2, and GAD-Mini ...

The purpose of this study was to translate the Bedtime Procrastination Scale (BPS) into Spanish and to evaluate its psychometric properties. A sample of 419 students from three Peruvian universities participated in the study. Confirmatory factor analysis was conducted to evaluate the original model of the scale, which initially showed poor fit indices. Improved fit indices were obtained after removing reverse-scored item, χ²(5) = 9.240, CFI = .998, RMSEA = .045, TLI = .997, and SRMR = .013. The internal consistency of the scale, examined using the omega coefficient, was found to be satisfactory (ω = .86). Moreover, measurement invariance analysis supported gender invariance, indicating that the scale functions equivalently across male and female participants. Additionally, convergent validity was assessed by examining the correlations between the BPS and insomnia, as measured by the A...

The aim of the study was to examine the psychometric properties of the Liebowitz Social Anxiety Scale (LSAS), analyzing factor structure and internal consistency. The sample was composed of 549 undergraduate students of a Peruvian public university. Confirmatory factor analysis was used in order to compare models of two, three, four, five and six factors. The best model fit indices were found in the five-factor model proposed by Caballo, Salazar, Arias, Hofmann & Curtis (2019), χ² = 319.43, CFI = .991, RMSEA = .043, TLI = .990, SRMR = .051. Also, the internal consistency of the five factors was analyzed using omega coefficient which ranged from .81 to .62. In conclusion, LSAS presents appropriate psychometric properties and the results support the five-factor structure.

Uno de los tratamientos más utilizados para la depresión son las terapias conductuales y entre ellas la terapia de activación conductual (TAC). Este tratamiento muestra ser una adecuada alternativa frente a la tradicional terapia cognitiva, aunque poco se sabe sobre su eficacia en población universitaria. El objetivo de este trabajo es analizar los efectos de la TAC en una muestra de universitarios iqueños. Se formaron dos grupos con estudiantes que cumplían con los criterios diagnósticos de la depresión: el experimental (GE) que recibió 12 sesiones de TAC (n= 19) y el de control (GC) que era una lista de espera (n= 20). Se evaluó la sintomatología depresiva, el grado de activación, el nivel de afectación en el trabajo/estudio y vida social, así como el grado de recompensa que aporta el entorno de ambos grupos al inicio y al final de la intervención utilizando el Inventari...

El trastorno de ansiedad social es un trastorno frecuente en el ámbito clínico y que a pesar de ello, se carece en nuestro medio de instrumentos psicológicos validados para poder elaborar un adecuado diagnóstico. La elaboración de pruebas psicológicas que midan este trastorno es necesaria, no sólo para mejores resultados en el ámbito clínico, sino para poder comprender mejor a la problemática en nuestro medio. Por estas razones surge la motivación de validar la Escala de Ansiedad Social de Liebowitz. Este trabajo ha sido estructurado en cinco capítulos. El primer capítulo está formado por el planteamiento del estudio, estableciendo el problema de investigación y los objetivos planteados. Además se expone la importancia y justificación de la investigación. El segundo capítulo trata acerca del marco teórico, abarcando información sobre la ansiedad social, modelos psico...
