    Introduction We live in a society marked by the speed and immediacy of digital systems that cause an inclination towards instant gratification. This trend is having a direct impact on university contexts, affecting how students approach their academic tasks. Aim To design and validate an instant gratification scale in the context of university academic tasks (GI-12). Method An instrumental study was conducted with an intentionally non-probabilistic sample of 1,145 university students from both sexes across the three regions of Peru. The instrument was developed in 10 stages following the recommendation of experts in the field. The first version consisted of 27 items with response options in a five-point Likert format. The analysis aimed to assess content-based validity, internal structure-based validity, and reliability. Results All items proved to be clear, relevant, and representative (V > .70). The analysis with AFE suggested an underlying structure of two factors: avoidance of prolonged effort (F1) and search for immediate gratification and distraction (F2), composed of 12 items (KMO = .91, Bartlett = p ≤ .001), with factor loadings greater than the cut-off .40 (.42 and.81). Subsequently, the AFC corroborated this structure (RMSEA = .041, SRMR = .045, CFI = .968). Regarding its reliability, it achieved an Omega coefficient of 0.88 for the first factor and 0.79 for the second factor. Conclusion The IG-12 presents its first psychometric evidence, which suggests that this tool is valid and reliable. In this way, it is the first measure with which the tendency to prefer immediate rewards over prolonged efforts required in the fulfillment of university academic tasks can be evaluated.

    impulsar la producción científica estudiantil en el Perú requiere de motivación para publicar artículos científicos. Frente a ello, el objetivo del estudio fue diseñar y validar la escala de motivación para publicar un artículo científico en universitarios peruanos. estudio transversal de tipo instrumental, donde participaron 417 universitarios de ciencias de la salud (58,0% mujeres), de entre 18 y 35 años de edad (ME = 20,77, DS = 3,49), quienes fueron seleccionados bajo un muestreo no probabilístico por conveniencia. Se reclutaron participantes de Medicina, Enfermería, Psicología y Nutrición, de 2 universidades del sur del Perú (privada y estatal). La escala se diseñó en 5 etapas siguiendo estándares internacionales. Para evaluar la validez basada en el contenido se utilizó el coeficiente V de Aiken, para analizar la estructura interna se recurrió al análisis factorial confirmatorio y la fiabilidad a través del coeficiente Omega. todos los ítems obtuvieron una evaluación favorable en el juicio de expertos (V > 0,70). El análisis factorial confirmatorio apoyó una estructura interna compuesta por 9 ítems distribuidos en un factor, reportando índices de bondad de ajuste satisfactorios (Chi2 = 62,72 con 27 gl, CFI = 0,98, TLI = 0,97, RMSEA = 0,05, SRMR = 0,02 y WRMR = 0,06). Por último, la confiabilidad alcanzó un nivel muy aceptable (ω = 0,96). la escala MOPu-AC demuestra evidencias psicométricas iniciales de validez basada en el contenido, estructura interna y fiabilidad en universitarios del sur peruano, por tanto, puede ser útil como herramienta de gestión de la investigación formativa. Promoting student scientific production in Peru requires motivation to publish scientific articles. The objective of this study was to design and validate the scale of motivation to publish a scientific article in Peruvian university students. Cross-sectional instrumental study, in which 417 university students of health sciences (58.0% women), aged 18 to 35 years (SD = 20.77, SD = 3.49), who were selected under a non-probabilistic convenience sampling, participated. Participants were recruited from medicine, nursing, psychology and nutrition, from two universities in southern Peru (private and state). The scale was designed in 5 stages, following international standards. Aiken's V coefficient was used to assess content-based validity, confirmatory factor analysis was used to analyze internal structure, and reliability was assessed by means of the Omega coefficient. All items obtained a favorable evaluation in the expert judgment (V > 0.70). The confirmatory factor analysis supported an internal structure composed of 9 items distributed in 1 factor, reporting satisfactory goodness-of-fit indices (Chi2 = 62.72 with 27 gl, CFI = 0.98, TLI = 0.97, RMSEA = 0.05, SRMR = 0.02 and WRMR = 0.06). Finally, reliability reached a very acceptable level (ω = 0.96). The MOPu-AC scale demonstrates initial psychometric evidence of content-based validity, internal structure and reliability in university students in southern Peru; therefore, it may be useful as a management tool for formative research.

    La creación de instrumentos de medición son aportes significativos para la medición y el avance de la investigación científica. Diseñar y validar una Escala de Maltrato al Asesorado de Tesis (EMAT) en una muestra de tesistas peruanos. Estudio de diseño instrumental donde se diseñó y se validó una escala de 20 ítems distribuidos en 3 factores (asesor, jurado y administrativos). Tuvo la participación de 274 tesistas (61,7% mujeres). Para analizar la evidencia de validez basada en el contenido se utilizó el coeficiente V de Aiken, para la validez de constructo se recurrió al análisis factorial confirmatorio y la confiabilidad fue estudiada a través del coeficiente omega. Se obtuvieron propiedades psicométricas adecuadas. Los 20 ítems de la EMAT recibieron una evaluación favorable a través del juicio de expertos, el análisis factorial confirmatorio apoya la estructura interna de 3 factores, reportando índices de bondad de ajuste satisfactorios, además, la correlación entre los factores fue significativa (p < 0,05) y la confiabilidad aceptable. La EMAT es válida y confiable para medir el maltrato hacia el asesorado de tesis. The creation of measurement instruments are significant contributions to the measurement and advancement of scientific research. To design and validate a Thesis Advisor Abuse Scale (EMAT) in a sample of Peruvian thesis students. Instrumental design study where a scale of 20 items distributed in 3 factors (advisor, jury and administrative) was designed and validated. It had the participation of 274 thesis students (61.7% women). The Aiken V coefficient was used to analyze the evidence of content-based validity, the confirmatory factor analysis was used for construct validity, and reliability was studied through the Omega coefficient. Adequate psychometric properties were obtained. The 20 items of the EMAT received a favorable evaluation through expert judgment, the confirmatory factor analysis supports the internal structure of 3 factors, reporting satisfactory goodness-of-fit índices, in addition, the correlation between factors was significant (P<.05) and the reliability acceptable. The EMAT is valid and reliable for measuring mistreatment of the thesis advisor.

    Background: In Peru, there are alarming statistics regarding traffic accidents caused by drivers under the influence of alcohol and emotional problems. Objective: This study aimed to identify whether alcohol consumption and depressive symptoms are predictors of the perception of risky behaviors in drivers. Method: The methodology followed a quantitative approach with a predictive scope, non-experimental design, and cross-sectional study. A non-probabilistic sample of 310 drivers aged 18 to 54 years was used, of whom 95% were male. The study utilized the Alcohol Use Disorders Identification Test (AUDIT), the Patient Health Questionnaire-9 (PHQ-9), and the Aversion to Risk Taking Scale to assess the participants. Results: Four out of 10 drivers exhibited depressive symptoms, and 7 out of 10 presented alcohol consumption issues. Regarding linear regression, an increase in alcohol consumption and depressive symptoms predicted 48.3% of the variance in the perception of risky driving behaviors. Conclusion: It is concluded that increased depressive symptoms and alcohol consumption are predictors of a decreased perception of risky driving behaviors. Future studies could implement interventions aimed at reducing risky behaviors by addressing depression and alcohol dependency in drivers.
