The study establishes the psychometric evidences of the Entrepreneurial Behavior Scale (EBS) in a sample of university students (N = 865) where 526 (60.8%) were women and 339 (39.2%) were men. Evidences of Aiken's content validity (p<.01 or p<.05) were found, indicating that the items are clear, coherent and relevant; as well as of internal structure, verifying the three-dimensional model, with adequate fit indices (RMR = .05, AGFI = .94, NFI = .92, RFI = .91, PNFI = .84). Finally, reliability by internal consistency was found with the Omega coefficient (ω > .70). It is concluded that the Entrepreneurial Behavior Scale (EBS) presents adequate evidences of validity and reliability.     Received: 18 August 2022 / Accepted: 19 October 2022 / Published: 5 November 2022

Esta investigación tuvo como objetivo principal determinar la evidencia del análisis psicométrico de la Escala de Reactancia Psicológica en Estudiantes de Cuarto y Quinto año de secundaria de las instituciones Educativas de la ciudad de Piura.  Así también el diseño de investigación es instrumental. La muestra de estudio estuvo conformada por alumnos del cuarto y quinto año de secundaria de las Instituciones Educativas de Piura sumando un total de 382 estudiantes (290 varones y 92 mujeres). El instrumento que se utilizó es la Escala de Reactancia Psicológica de Hong -HPRS- (Hong y Faedda, 1996), utilizado para medir la reactancia psicológica. Este instrumento está formada por 14 ítems que están basados en la teoría de la reactancia de Brehm (1966). Finalmente se puede concluir que los procesos  psicométricos evidenciaron la validez de la escala de reactancia psicológica de Hong en estudiantes de cuarto y quinto año de secundaria de las Instituciones Educativas de Piura. Esto significa que el instrumento es  válido y confiable para ser aplicado en la ciudad de Piura solo a estudiantes de cuarto y quinto de secundaria de las diferentes instituciones educativas.

The university population had to adapt to new ways of learning causing in them a strong emotional impact. Therefore, there is a need for an instrument with adequate psychometric properties to develop a profile of perceived stress. Objective: To demonstrate the psychometric properties of the EEP-10 Perceived Stress Scale and to characterize perceived stress according to sociodemographic profile in university students. Method: Instrumental and non-experimental design, sample of 820 university students from 16 to 42 years of age, probabilistic sampling. Results: The internal structure of the scale presents a good fit of the two-dimensional model with RMR= .036; AGFI= .985; NFI= .982, RFI= .976 and PNFI= .791, as well as factor loadings between .643 and .797. A reliability of .835 and .825 omega coefficient for each of the dimensions. In the General Distress dimension of perceived stress, it was found that the differences according to sociodemographic variables differed from null, gender (p=.000**), age (p=.003**), economic dependence (p=.001**), and the effect size of the differences was of small magnitude. Discussion and conclusions: The study showed adequate psychometric properties of the perceived stress scale and differences in perceived distress according to sex, age and economic dependence. However, no differences were found in coping capacity based on sociodemographic variables.   Received: 24 February 2023 / Accepted: 28 May 2023 / Published: 5 July 2023
