Resumen
La presente investigación tuvo como objetivo principal validar el Inventario de Síntomas Prefrontales (ISP) en una muestra de adultos jóvenes colombianos, con el fin de establecer su fiabilidad como herramienta de evaluación de la sintomatología asociada a la disfunción de la corteza prefrontal. En Colombia, actualmente no se dispone de instrumentos psicométricos validados que permitan identificar de manera precisa los síntomas derivados de alteraciones en el lóbulo frontal, lo que limita tanto el ejercicio clínico como el desarrollo investigativo en el área de la neuropsicología.
Se adoptó un enfoque cuantitativo con un diseño de tipo descriptivo y transversal, aplicando el ISP a una muestra representativa de 305 adultos jóvenes entre 18 y 35 años. Para el análisis de los datos se emplearon procedimientos estadísticos como el coeficiente alfa de Cronbach para determinar la consistencia interna del instrumento, y pruebas factoriales exploratorias para verificar la validez de constructo.
Los resultados evidenciaron adecuados niveles de fiabilidad y validez en las tres dimensiones del instrumento: control comportamental, control emocional y conducta social,
confirmando la estructura factorial previamente propuesta por los autores del ISP. Estos hallazgos respaldan el uso del inventario como un recurso válido y confiable para la evaluación de funciones ejecutivas y síntomas relacionados con la disfunción prefrontal en contextos clínicos y académicos del país.
La validación de este instrumento representa una contribución significativa para el campo de la psicología en Colombia, ya que fortalece la capacidad diagnóstica de los profesionales y abre nuevas posibilidades para la investigación en neuropsicología, especialmente en poblaciones jóvenes.
The main objective of this research was to validate the Prefrontal Symptoms Inventory (ISP) in a sample of young Colombian adults, in order to establish its reliability as an assessment tool for symptoms associated with prefrontal cortex dysfunction. In Colombia, there are currently no validated psychometric instruments that allow for the precise identification of symptoms derived from frontal lobe alterations, which limits both clinical practice and research development in the field of neuropsychology. A quantitative approach with a descriptive and cross-sectional design was adopted, applying the ISP to a representative sample of 305 young adults aged 18 to 35. For data analysis, statistical procedures such as Cronbach’s alpha coefficient were used to determine the internal consistency of the instrument, and exploratory factor analyses were conducted to verify construct validity. The results showed adequate levels of reliability and validity in the three dimensions of the instrument: behavioral control, emotional control, and social behavior, confirming the factorial structure previously proposed by the ISP authors. These findings support the use of the inventory as a valid and reliable resource for the evaluation of executive functions and symptoms related to prefrontal dysfunction in clinical and academic contexts within the country. 4 The validation of this instrument represents a significant contribution to the field of psychology in Colombia, as it strengthens the diagnostic capacity of professionals and opens new possibilities for research in neuropsychology, especially in young populations.
