ABSTRACT
Background/Objective:
Although alcohol, tobacco and cannabis are the most widely consumed drugs, sparse data exist regarding polydrug use in adolescents and its relationship with impulsivity. This study aims to identify trajectories of polydrug use and analyze differences in impulsivity between them.Method:
A total of 1,565 adolescents (54.4% males; mean age = 13.02, SD = 0.57) were annually assessed over three years using the Barratt Impulsiveness Scale, the Zuckerman Impulsive Sensation Seeking Scale, a Stroop Test and a Delay Discounting Task. Frequency of alcohol, tobacco, and cannabis use, intoxication episodes and problem drinking were also assessed. Polydrug trajectories were identified using latent class mixed modelling. To examine differences in self-reported and behavioral impulsivity two mixed multivariate analyses of covariance were used.Results:
Three trajectories of substance use were found. The Experimental use' and the 'Early use' trajectories presented the lowest and highest impulsivity, respectively. Substance use increases in the Telescoped used trajectory were associated with parallel increases in impulsivity.Conclusions:
individuals with divergent patterns of substance use during adolescence differ in their impulsiveness, primarily in general impulsivity and sensation seeking. Present findings suggest the relevance of these facets as possible targets for interventions preventing the onset and escalation of substance useRESUMEN
Antecedentes/Objetivo:
A pesar de que el alcohol, tabaco y cánnabis son las drogas más utilizadas, existen pocos estudios sobre policonsumo y su relación con la impulsividad en adolescentes. Los objetivos de este estudio son identificar trayectorias de policonsumo y analizar diferencias en impulsividad.Método:
Se evaluaron anualmente 1.565 adolescentes (54,4% hombres; edad media = 13,02, DT = 0,57) durante tres años usando la Escala de Impulsividad de Barratt, la Escala de Búsqueda de Sensaciones de Zuckerman y las Tareas de Stroop y Descuento por Demora. Se evaluó el uso de alcohol, tabaco, cannabis, uso problemático de alcohol y borracheras. Se usaron modelos mixtos de clases latentes y análisis mixtos multivariados de covarianza.Resultados:
Se encontraron tres trayectorias de policonsumo. Las trayectorias de "Uso experimental" y "Uso temprano" presentaron los menores y mayores niveles de impulsividad, respectivamente. Los incrementos en el consumo de la trayectoria de "Escalamiento" se asociaron con incrementos paralelos en la impulsividad.Conclusiones:
Las personas con distintos patrones de consumo de sustancias durante la adolescencia difieren en sus niveles de impulsividad, principalmente en impulsividad general y búsqueda de sensaciones. Los resultados sugieren la relevancia de estas facetas como dianas para prevenir el inicio y escalamiento del consumo
