Therefore, this paper presents the psychometric properties of the Situational Inventory for Tobacco Consumers (ISTC) that was constructed from an initial study with focus groups and expert analysis. The instrument consists of 46 items that were applied to a sample of 342 people. The results showed that the item bank has a high reliability (a= 0,96). We present the classic indexes along with the analysis based on an item response theory model, where the inventory showed an appropriate fit (X2= 749,539, df = 709, p = 0,141). Aditionally, evidence for the concurrent validity of the proposed test was obtained through a regression analysis where the scores from the Test for Nicotine Dependence were able to explain a large amount of the ISCT score variance (R2= 43.8). It is therefore considered that this inventory is able to guide the specialists in the planning of specific treatments catered to the consumption situations of each individual. El conocimiento de las situaciones relacionadas con dejar de fumar y la abstinencia prolongada permite que se puedan llevar a cabo tratamientos específicos que eviten las recaídas y mantengan la efectividad del tratamiento a largo plazo. A pesar de su importancia, no existe una escala que permita identificar las situaciones asociadas al consumo. En esta investigación se presenta las propiedades psicométricas del Inventario Situacional para Consumidores de Tabaco (ISCT) que se construye a partir de un estudio inicial con grupos focales y un análisis de expertos; está constituido por 46 ítems que se aplican a una muestra de 342 sujetos. Los resultados mostraron que el banco de ítems tiene una fiabilidad alta (a= 0,96). Se presentan los índices clásicos y se realiza un análisis con la Teoría de la Respuesta al Ítem, y el modelo demuestra un ajuste adecuado (X2= 749,539, gl=709, p=0,141). Adicionalmente, se realizó un análisis de validez concurrente con los resultados del Cuestionario de Fagerström para la Dependencia a la nicotina en el que se muestra, a partir de un análisis de regresión, que el nivel de dependencia explica un porcentaje amplio de la varianza del ISCT (R2= 43.8). Por lo tanto, se considera que el inventario permite dirigir a los especialistas en la planeación de un tratamiento específico a las situaciones de consumo de cada individuo. 2009-06-30 2020-06-16T22:19:10Z 2020-06-16T22:19:10Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo revisado por pares https://revistas.usantotomas.edu.co/index.php/diversitas/article/view/91 10.15332/s1794-9998.2009.0001.05 http://hdl.handle.net/11634/25314 spa https://revistas.usantotomas.edu.co/index.php/diversitas/article/view/91/111 https://revistas.usantotomas.edu.co/index.php/diversitas/article/view/91/112 application/pdf text/html Universidad Santo Tomás, Bogotá, Colombia Diversitas; Vol. 5 Núm. 1 (2009) 2256-3067 1794-9998 Diversitas; Vol. 5 No. 1 (2009)
