Tell me who your friends are?! The mediating role of friends' use in cannabis abuse

Abstract Objectives To evaluate the relationship between age at onset of cannabis use and cannabis abuse in a sample of Portuguese cannabis users, testing the mediating role of the number of friends using cannabis and comparing these relationships between male and female subsets. Method A sample of 529 Portuguese cannabis users comprising 276 males and 244 females aged from 14 to 21 years completed a sociodemographic questionnaire, the Cannabis Abuse Screening Test (CAST), and answered four questions related to cannabis use. Data were analyzed using the PROCESS macro in SPSS version 26.0. Results Age at onset of cannabis use was negatively related to the number of friends using cannabis, while the number of friends using cannabis had a positive relationship with cannabis abuse. As predicted, the number of friends using cannabis seems to have a mediating role in the relationship between cannabis onset age use and cannabis abuse, since the indirect effect was found to be significant. The pattern of the relationships among the variables observed was found to be similar for both male and female subsets of the sample. However, males reported higher cannabis abuse than females. Conclusion The results highlight the mediating role of friends' use of cannabis in the relationship between age at onset of cannabis use and users' abuse. These results highlight the importance of early intervention in cannabis use. In particular, the pattern of the relationships observed among the studied variables emphasizes the need to monitor and conduct peer training interventions or interventions to promote of social skills.

Social networks as tools for the prevention and promotion of health among youth

Abstract The emergence of information and communication technologies (ICT) has generated a number of research questions, related to their use and potential risk, but also potentials for prevention or health promotion. Online social networks have become an important source of information for users as well as a tool for social relations. As traditional social networks, they can act as vehicles to improve the health of adolescents and youth, as well as play a key role in an educational context. The aim of this work is then to explore the theoretical relevance of ICT, particularly on online social networks, on disease prevention and health promotion of communicable diseases. Literature review points out the role of online social networks, particularly in the field of sexual health, body image, especially eating habits and overweight, as well as smoking and alcohol dependence. Data allow us to understand how online social network behavior and interaction is related to their burden and interventions developed in sexual health and addiction show positive results. More efforts in body image are needed in order to use these tools for prevention and promotion of health from early age.

Preditores do uso do Facebook pelos adolescentes portugueses: Contributos de um estudo exploratório / Predictors of Facebook use among Portuguese adolescents: Contributes of an exploratory study

Resumo A generalização do uso das redes sociais online, tem trazido oportunidades e constrangimentos ao mesmo tempo-ou até mais depressa-que a investigação e o conhecimento sobre este tópico. Neste trabalho, pretendemos explorer o papel de variáveis pessoais e psicossociais no uso do Facebook, recorrendo a um conjunto de questionários de autorrelato junto de uma amostra de 386 adolescentes portugueses. Os resultados obtidos permitem verificar diferenças na utilização em função do género, uma relação positiva com a idade, a autorregulação e autoestima, sendo a interação com pares da sua rede de contactos offline o mais forte preditor para o uso das redes sociais. Estes dados sugerem o papel desta aplicação como um meio para manter o contacto com os pares.

Abstract The widespread use of social networks has brought opportunities and constraints at the same time, even faster than research and knowledge on this topic. In this paper, we intend to explore the role of personal and psychosocial variables in Facebook use, considering a set of self-report questionnaires to a sample of 386 Portuguese adolescents. We found gender differences in social network use, a positive relationship with age, self-regulation and self-esteem, with peer interaction with offline contacts as the strongest predictor for social network use. These data suggest the role of this application as a mean to maintain contact with peers.
