Las elecciones impulsivas pueden ser evaluadas mediante tareas de descuento por demora, esto permite comparar los valores entre el consumo inmediato y el diferido de un bien determinado. Se utilizó la escala de Delay Discounting (DD) para evaluar la respuesta al retraso, y el cuestionario BIS-11, para medir la impulsividad. La muestra constó de 277 sujetos. Se realizó un Análisis Factorial Confirmatorio sobre la Escala DD, que mostró un buen ajuste al modelo teórico (CFI = 0.928–0.931; TLI = 0.904–0.908; SRMR = 0.057), con una adecuación muestral aceptable (KMO = 0.78). La fiabilidad fue adecuada para ambas dimensiones: las cuales además se asociaron significativamente. Respecto al BIS-11, la media fue 58.03 (±10.67), con una alta confiabilidad como factor único. Se hallaron correlaciones relevantes entre ambas escalas. Evidenciando relaciones significativas entre la aversión al retraso y distintos componentes de la impulsividad,Esto resalta la importancia de validar adecuadamente la escala Delay Discounting,para contar con un instrumento confiable y bien adaptado permite comprender el rol del tiempo en la toma de decisiones.

The Delay Discounting (DD) scale was used to evaluate delay-related responses, and the BIS-11 questionnaire was employed to measure impulsivity. The sample consisted of 277 participants. A Confirmatory Factor Analysis was conducted on the DD scale, showing a good fit to the theoretical model (CFI = 0.928–0.931; TLI = 0.904–0.908; SRMR = 0.057), with acceptable sampling adequacy (KMO = 0.78). Reliability was adequate for both dimensions, which also showed significant associations with each other. Regarding the BIS-11, the mean score was 58.03 (±10.67), with high reliability as a single factor. Relevant correlations were found between the two scales, indicating significant relationships between delay aversion and various components of impulsivity. This underscores the importance of properly validating the Delay Discounting scale, as having a reliable and well-adapted instrument enables a better understanding of the role of time in decision-making.
