Abstract(s)
O consumo de substâncias ou drogas em estudantes universitários é considerado um problema considerável, uma vez que este consumo pode afetar negativamente a saúde física e psicológica, bem como o sucesso académico dos estudantes universitários. O presente estudo procura testar o papel da variável perceção de risco relacionado com o consumo de substâncias enquanto variável mediadora da relação entre o consumo de álcool, tabaco e canábis e as consequências relacionados com esse consumo numa amostra de estudantes universitários a frequentar o ensino superior em Portugal. A amostra do presente estudo foi composta por 124 estudantes a frequentar cursos em diferentes universidades portuguesas. Os dados foram recolhidos através da utilização de um questionário online de autopreenchimento desenvolvido para avaliar o consumo de álcool, tabaco e canábis, a perceção de risco e as consequências relacionados com esse consumo. Os resultados obtidos indicam que a perceção de risco encontra-se negativamente associada com o consumo de todas as substâncias consideradas. Os níveis de consumo das substâncias demonstraram estar positivamente relacionados entre si. Os resultados obtidos indicam também que a perceção de risco encontra-se positivamente associada com a perceção de consequências positivas relacionadas com consumo. Quanto ao papel da perceção de risco enquanto variável mediadora, verificou-se a existência de uma mediação por parte da perceção de risco da relação existente entre o consumo de álcool, tabaco e canábis e as consequências positivas. Em suma, o presente estudo contribui para a compreensão das relações envolvidas na decisão de consumir substâncias por parte de estudantes universitários, enfatizando a necessidade de considerar o papel que a perceção de risco poderá exercer na relação entre o consumo de substâncias e as consequências relacionados com o consumo. No seu conjunto, as conclusões do presente estudo necessitam de ser consideradas no desenvolvimento de estratégias de prevenção e programas de intervenção focados na mudança da perceção de risco que os estudantes universitários têm sobre o consumo de certas substâncias ou drogas, no sentido reduzir esse consumo, bem como aliviar o impacto das consequências adversas relacionadas com o consumo nesta população.
The consumption of substances or drugs among university students is considered a significant issue, as this consumption can negatively impact both physical and psychological health, as well as academic success. The present study seeks to test the role of the risk perception variable associated with substance use as a mediating variable in the relationship between alcohol, tobacco, and cannabis use and the related consequences among a sample of university students attending higher education in Portugal. The sample of this study consisted of 124 students enrolled in courses at diferente Portuguese universities. Data were collected through an online self-administered questionnaire designed to assess alcohol, tobacco, and cannabis use, risk perception, and the consequences associated with such use. The results indicate that risk perception is negatively associated with the consumption of all considered substances. The consumption levels of the substances were shown to be positively related to each other. Additionally, the results suggest that risk perception is positively associated with the perception of positive consequences related to consumption. Regarding the role of risk perception as a mediating variable, it was found that risk perception mediates the relationship between alcohol, tobacco, and cannabis consumption and positive consequences. In summary, the present study contributes to understanding the relationships involved in university students' decisions to use substances, emphasizing the need to consider the role that risk perception may play in the relationship between substance use and its consequences. Overall, the conclusions of this study should be considered in the development of prevention strategies and intervention programs focused on changing university students' risk perception regarding the consumption of certain substances or drugs, aiming to reduce this consumption and mitigate the impact of adverse consequences related to use within this population.
