Abstract
La Substance Dependence Severity Scale –SDSS- es una de las pocas
escalas que evalúa la dependencia y abuso a sustancias según criterios
DSM en términos dimensionales. Diferentes estudios psicométricos
han aportado evidencias de validez y fiabilidad en su versión inglesa,
aunque no se dispone de una versión en español. El objetivo de
este trabajo ha sido describir el proceso de adaptación seguido de
la versión inglesa de la SDSS al castellano, y aportar resultados
preliminares sobre su fiabilidad y evidencias de validez.
Han participado en el estudio 146 pacientes (79.6% hombres) admitidos
a tratamiento en el Centro Provincial de Drogodependencias de Huelva
consumidores de alcohol, cocaína, heroína y cannabis. Además de la
SDSS, se administró la EUROPASI y el Test para la Evaluación de la
Calidad de Vida en Adictos a Sustancias Psicoactivas -TECVASP-.
La escala de gravedad de la dependencia ha mostrado adecuadas
propiedades psicométricas en términos de sus índices de
discriminación y de consistencia interna (α=0.881 para alcohol;
α=0.814 para cocaína; α=0.531 para cannabis; α=0.785 para heroína).
En cambio la escala que evalúa el abuso ha mostrado resultados más
deficientes. Sobre las evidencias de validez, las evidencias basadas en
la estructura interna han mostrado una estructura unidimensional.
Además, las evidencias obtenidas basadas en la relación con otras
variables apoyan empíricamente las relaciones teóricas postuladas.
Los resultados preliminares apoyan el uso de la escala de gravedad
de la dependencia. La escala de gravedad que evalúa los criterios de
abuso necesita más evidencia empírica para conocer la utilidad de la
misma. Por lo tanto, no es aconsejable su uso según la versión actual.
Palabras claves: Substance Dependence Severity Scale –SDSS-;
adaptación, fiabilidad y validez, gravedad de la dependencia.
The Substance Dependence Severity Scale –SDSS- is one of the few scales that assesses substance dependence and abuse according DSM criteria in dimensional terms. Several studies have provided evidence of psychometric validity and reliability in its English version, but there is no Spanish version available. The aim of this work was to describe the adaptation process of the English version of the SDSS into Spanish, and provide preliminary results on its reliability and validity evidence. Participants were 146 patients (79.6% male), consumers of alcohol, cocaine, heroin and cannabis admitted to treatment in the Drug Abuse Centre Services of Huelva. Besides the SDSS, the EUROPASI and the Health Related Quality of Life for Drug Abusers test –HRQOLDAwere also administered. The Substance Dependence Severity Scale –SDSS- has shown adequate psychometric properties in terms of the rates of discrimination and internal consistency (α=0.881 for alcohol; α=0.814 for cocaine; α=0.531 for cannabis; α=0.785 for heroin). However, the scale assessing abuse showed poorer results. Concerning the validity evidence, the evidence based on internal structure showed a unidimensional structure. Furthermore, the evidence based from the relationships with other variables empirically support the theoretical relationships postulated. Preliminary results support the use of the Substance Dependence Severity Scale. The severity scale, which evaluates abuse criteria, needs further empirical evidence to assess its utility. Therefore, its current version is not recommended for use.
