La flexibilidad cognitiva es un componente del funcionamiento ejecutivo que implica la capacidad de adaptar la conducta a un entorno cambiante. El maltrato infantil ha sido asociado a deficiencias en el funcionamiento ejecutivo. Sin embargo, hay escasos estudios que clarifiquen la relación entre los diversos tipos de maltrato infantil y la flexibilidad cognitiva. El presente estudio se propone analizar el vínculo entre el autoinforme de trauma infantil, específicamente de los abusos y negligencias, y la flexibilidad cognitiva en población infantojuvenil sin patología psiquiátrica. Para ello se administraron las siguientes técnicas psicométricas: Test de Clasificación de Cartas de Wisconsin (WCST) y Cuestionario de Trauma Infantil (CTQ) a 54 menores (7 a 17 años) que asistieron a un Centro Cultural. Se analizaron las correlaciones entre el puntaje de errores perseverativos del WCST y el puntaje total del CTQ, y sus respectivos sub-puntajes: Abuso emocional, negligencia emocional, abuso físico y negligencia física. Se encontró una correlación significativa entre un mayor número de errores perseverativos y la negligencia emocional (rho = .323, p<05). Los resultados proporcionan evidencia que respalda las asociaciones entre autoinformes de Trauma y menor flexibilidad cognitiva y resaltan la necesidad de continuar indagando en esta dirección.

Child maltreatment has been associated with deficiencies in executive functioning. However, there are few studies that clarify the relationship between different types of child maltreatment and cognitive flexibility. This study aims to analyze the link between self-reported childhood trauma, specifically abuse and neglect, and cognitive flexibility in a population of children and adolescents without psychiatric pathology. The following psychometric techniques were administered: Wisconsin Card Sorting Test (WCST) and Childhood Trauma Questionnaire (CTQ) to 54 minors (ages 7 to 17) attending a Cultural Center. Correlations were analyzed between the perseverative errors score on the WCST and the total score on the CTQ, as well as their respective sub-scores: Emotional abuse, emotional neglect, physical abuse, and physical neglect. A significant correlation was found between a higher number of perseverative errors and emotional neglect (rho = .323, p<.05). The results provide evidence supporting the associations between self-reports of trauma and lower cognitive flexibility and highlight the need for further investigation in this direction.
