Abstract
La identificación de diferentes perfiles de personalidad de riesgo para
el consumo problemático de drogas es útil para prevenir problemas
relacionados con las drogas. Este estudio tiene como objetivo analizar
las propiedades psicométricas de una nueva versión de la Substance
Use Risk Profile Scale (SURPS) en estudiantes universitarios
españoles. Estudio de diseño transversal en el que participaron 455
estudiantes de cuatro universidades españolas. La nueva versión de la
SURPS adaptada a la población española fue administrada junto a la
Escala de Desesperanza de Beck, la UPPS-P, el inventario de ansiedadestado
(STAI) y el test AUDIT. La consistencia interna de las cuatro
subescalas de la SURPS osciló entre 0,652 y 0,806. Los coeficientes de
fiabilidad por el procedimiento de dos mitades oscilaron entre 0,686 y
0,829. La estimación test-retest osciló entre 0,733 y 0,868. Se replicó la
estructura factorial esperada de cuatro dimensiones. Como evidencias
de validez convergente, se encontró que las subescalas de la SURPS
se relacionaron significativamente con las medidas teóricamente
esperadas de otras escalas de personalidad y con el consumo de
alcohol. Esta versión de la SURPS constituye un instrumento útil
para la medición de rasgos de personalidad relacionados con la
vulnerabilidad al consumo de drogas y sus problemas relacionados,
pudiendo ser utilizada para estrategias de prevención del consumo
de drogas.
The identification of different personality risk profiles for substance misuse is useful in preventing substance-related problems. This study aims to test the psychometric properties of a new version of the Substance Use Risk Profile Scale (SURPS) for Spanish college students. Cross-sectional study with 455 undergraduate students from four Spanish universities. A new version of the SURPS, adapted to the Spanish population, was administered with the Beck Hopelessness Scale, the UPPS-P Impulsive Behavior Scale, the State-Trait Anxiety Inventory (STAI) and the Alcohol Use Disorders Identification Test (AUDIT). Internal consistency reliability ranged between 0.652 and 0.806 for the four SURPS subscales, while reliability estimated by split-half coefficients varied from 0.686 to 0.829. The estimated test-retest reliability ranged between 0.733 and 0.868. The expected four-factor structure of the original scale was replicated. As evidence of convergent validity, we found that the SURPS subscales were significantly associated with other conceptually-relevant personality scales and significantly associated with alcohol use measures in theoretically-expected ways. This SURPS version may be a useful instrument for measuring personality traits related to vulnerability to substance use and misuse when targeting personality with preventive interventions.
