Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicología del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Se presenta una escala breve derivada de la Escala para la Evaluación del Síndrome de la Dependencia de la Nicotina (NDSS). A una muestra de 1.061 fumadores diarios, evaluados en Centros de Atención Primaria, Unidad de Alcoholismo y Unidad de Tabaquismo, se les aplicó la NDSS y la SCID para evaluar dependencia de la nicotina con criterios DSM-IV. Los resultados indican la existencia de un factor general de dependencia de la nicotina con la NDSS. Seleccionamos los ítems con mayor carga factorial (>0,50), obteniendo una escala corta de 6 ítems. Con ella obtenemos resultados semejantes a los de la escala total en las distintas variables del estudio (sociodemográficas y de consumo de cigarrillos). Su fiabilidad es buena (alfa= 0,79), la correlación entre la escala corta y la total es muy alta (r= 0,95, p<,001) y discrimina a los fumadores en función del consumo de cigarrillos y dependencia de la nicotina, tal y como hemos evaluado con la SCID. Su funcionamiento según las curvas ROC es excelente (área de 0,84 bajo la curva). Todo ello sugiere la utilidad de esta escala breve (NDSS-S) para evaluar la dependencia de la nicotina en fumadores.
The Short Nicotine Dependence Syndrome Scale (NDSS-S) in Spanish smokers. We present a brief scale derived from the Nicotine Dependence Syndrome Scale (NDSS). We used a sample of 1.061 daily smokers, which was obtained from five Primary Care Health Centers, a Unit of Alcoholism, and a Smoking Cessation Unit. All smokers were evaluated with the NDSS and the SCID to assess nicotine dependence according to DSM-IV criteria. The results indicate the existence of a general factor of nicotine dependence according to the NDSS. We selected the items with a higher factor loading (>.50), obtaining a short scale of 6 items. With this brief scale, we obtained results similar to those of the total scale in the diverse variables (sociodemographic and smoking) of the study. Scale reliability is satisfactory (a= .79), the correlation between the short and the total scale is very high (r=.95, p<.001) and the short scale discriminates the smokers in terms of cigarette consumption and nicotine dependence, as assessed with the SCID. The operation under the ROC curve is excellent (area under the curve .84). The data indicate the usefulness of this brief scale (NDSS-S) to assess nicotine dependence in smokers.
