Se aplicó la Escala del Síndrome de Dependencia de la Nicotina (NDSS) a una muestra de 241 fumadores que demandaron tratamiento para dejar de fumar. Los resultados indican que el factor general que evalúa dependencia de la nicotina (NDSS-T) tiene buena fiabilidad (alfa de Cronbach= 0.80) y se confirman los cinco factores originales de la escala (impulso, continuidad, tolerancia, prioridad y estereotipia). El NDSS-T correlaciona significativamente con el Test de Fagerström de Dependencia de la Nicotina, con los criterios de dependencia de la nicotina del DSM-IV evaluados con la entrevista SCID, con el número de cigarrillos fumados y con el monóxido de carbono en el aire espirado. Las curvas ROC indican que el NDSS-T tiene una puntuación de 0.86 bajo la curva, lo que indica que predice adecuadamente la dependencia de la nicotina. Todos los resultados obtenidos en el presente estudio indican la utilidad de este instrumento para evaluar adecuadamente la dependencia de la nicotina en fumadores.
The Nicotine Dependence Syndrome Scale (NDSS) in a sample of smokers who demand smoking cessation treatment. The Nicotine Dependence Syndrome Scale (NDSS) was applied to a sample of 241 smokers who demanded treatment to stop smoking. The results indicate good reliability (Cronbach’s alpha= 0.80) of the general factor that evaluates nicotine dependence (NDSS-T), and the five original factors obtained by factor analysis are confirmed (drive, continuity, tolerance, priority and stereotypy). The NDSS-T correlates significantly with the Fagerström Test for Nicotine Dependence, with DSM-IV diagnostic criteria assessed with the SCID, the number of cigarettes smoked and carbon monoxide in expired air. The ROC curves show that the NDSS-T has a score of 0.86 under the curve, which indicates a good prediction of nicotine dependence. All the results obtained in this study indicate the utility of this scale to assess nicotine dependence in smokers.
