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.

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.

Resumo: A investigação sugere que a relação entre resiliência e uso de substâncias é um processo psicológico não linear e multifatorial. Surpreendentemente, o processamento sensorial raramente é evocado enquanto variável associada a estes fenômenos. O objetivo deste estudo foi investigar as relações entre processamento sensorial, resiliência, atitudes e frequência de comportamentos de consumo de álcool, tabaco e outras substâncias psicoativas em adultos saudáveis. Foram empregados quatro instrumentos: Perfil Sensorial para Adolescentes e Adultos; Escala de resiliência; Escalas de atitudes; Escala de consumo de tabaco, álcool e outras drogas. A amostra foi constituída por 340 participantes adultos mentalmente saudáveis, dos quais 261 (76.8%) eram mulheres. Quanto à idade cronológica, o indivíduo mais novo tinha 18 anos e o mais velho tinha 76 anos (M = 39; DP = 11). O processamento sensorial apresentou-se associado a atitudes e condutas de consumo. Os desequilíbrios sensoriais parecem estar implicados na diminuição da resiliência.

Abstract: Research suggests that the relationship between resilience and substance use is a non-linear and multifactorial psychological process. Surprisingly, sensory processing is rarely mentioned as a variable associated with this phenomenon. In this study, we investigated the relationship between resilience, sensory processing, attitudes and consumption behaviors for alcohol, tobacco and other psychoactive substances. For this, we used four instruments: Adult / Adolescent Sensory Profile; Resilience Scale; Attitudes scales; Tobacco, Alcohol and Other Drug Use Scale. The sample consisted of 340 healthy adult participants, of whom 261 (76.8%) were women and 79 (23.2%) men. As for chronological age, the youngest person was 18 and the oldest was 76 years (M = 39; DP = 11). Sensory processing was associated with the intake behaviors and attitudes. Sensory imbalances appeared to be implicated in decreased resilience.

Resumen: Investigaciones sugieren que la relación entre la resiliencia y el uso de sustancias es un proceso psicológico no lineal y multifactorial. Sorprendentemente, el procesamiento sensorial raramente se menciona como una variable asociada a estos fenómenos. En el presente estudio fue investigado la relación entre el procesamiento sensorial, la resiliencia, las actitudes y el comportamiento de consumo de alcohol, tabaco y otras drogas. Fueron utilizados cuatro instrumentos de medida: Perfil Sensorial para Adolescentes y Adultos; Escala de Resiliencia; Escalas de Actitudes; Escala de consumo de alcohol, tabaco y otras drogas. La muestra fue constituida por 340 participantes adultos sanos, de los cuales 261 (76.8%) eran mujeres y 79 (23.2%) hombres. En cuanto a la edad cronológica, el individuo más joven tenía 18 años y el más viejo 76 años (M = 39; DP = 11). El procesamiento sensorial se mostró asociado a las actitudes y la conducta de consumo. Los desequilibrios sensoriales parecen estar implicados en la disminución de la resiliencia.

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.

O objetivo deste estudo foi apresentar os resultados da adaptação do Inventário de Autorregulação na Adolescência (IARA) para Portugal. O instrumento foi testado com duas amostras de estudantes do ensino secundário com a Escala de Autorregulação como medida de controle. No primeiro estudo, os instrumentos foram testados junto de 823 adolescentes e a análise de validade de construto foi feita com recurso à análise factorial exploratória. Os resultados indicaram uma estrutura apropriada com propriedades psicométricas adequadas referentes à validade de conteúdo e construto, e fidelidade. Um segundo estudo envolveu 435 adolescentes, sendo testados três modelos com análise factorial confirmatória. A versão final do IARA-2 apresenta valores de ajustamento aceitáveis em termos de validade de contruto e concorrente, dadas as correlações moderadas a elevadas com o sucesso acadêmico e uso de substâncias. As implicações desta nova abordagem ao estudo da autorregulação são discutidas e direções para próximos estudos são sugeridas.

In this study we present the results of the adaptation of the Adolescent Self-Regulatory Inventory (ASRI) to Portugal. The measure was used with two samples of high school students to which ASRI was administered with Self-Regulation Scale as control measure. In the first study the measures were administered to 823 adolescents and the construct validity analysis was assessed with exploratory factor analysis. The results allow us to find an adequate structure with proper psychometric properties, in their construct and content validity, and reliability. A second study involved 435 adolescents, being tested three models using confirmatory factor analyses. The final version of the ASRI-2 presents an acceptable fit of the data in construct and concurrent validity, given its moderate or high correlation with academic success and substance use. The implications of this new approach to the self-regulation study are discussed and directions to further studies are suggested.
