O papel da informação como medida preventiva ao uso de drogas entre jovens em situação de risco The role of information as a preventive drug measure among youth at risk

Entre os jovens, o uso de drogas ilícitas é um problema de saúde coletiva que desperta atenção. Poucos estudos sobre motivos para o não uso de drogas exploram o real papel da informação como método preventivo. O objetivo do estudo é analisar, entre adolescentes e jovens em situação de risco, os motivos para o não uso de drogas ilícitas, destacando o impacto da informação como fator protetor. Através de metodologia qualitativa, adotou-se uma amostra intencional, selecionada por informantes-chave e por "bola de neve". Foram entrevistados 62 adolescentes e jovens entre dezesseis e 24 anos, de baixa classe socioeconomica. Destes, 32 eram não usuários de drogas (NU) e trinta eram usuários pesados (U). Entre o grupo NU, a informação destacou-se como principal motivo de não uso, através do conhecimento de aspectos positivos e negativos. O principal meio de veiculação foi a família, seguido da observação da experiência negativa vivenciada por amigos que já faziam abuso. Em contrapartida, no grupo U, prevaleceu a falta de informação ou a disponibilidade de conhecimentos vagos. Dispor de informações adequadas sobre o tema "drogas" parece essencial à prevenção do uso experimental entre adolescentes e jovens em situação de risco. No entanto, a informação que mais parece eficaz é a transmitida pela família.<br>Illicit drug consumption among youngsters is a public health concern that requires attention. However, little research has highlighted the importance of "drug information availability" among protection factors. The objective of the study is to identify, from the point of view of youngsters at risk, what factors could prevent them to try illicit drugs, focusing on the importance of "drug information availability". An intentional sample was selected, composed by 62 youngsters divided into two groups: (NU) non illicit users N=32 and (U) users N=30. The sample was recruited through key-informants and snowball and each participant was submitted to an in-depth semi-structured interview. According to NU, "drug information availability" was reported as the main protector factor. Family-based information was the main source of knowledge followed by observation of the drug negative consequences on lives of friends who have already consumed illicit drugs in a regular-basis. Among users, a lack of drug knowledge or availability of partial information was reported. Among youngsters at risk, drug information availability is the main protection factor against experimental and regular drug consumption. Family based information was reported as its main source

Fine-Grained Semantic Categorization across the Abstract and Concrete Domains

A consolidated approach to the study of the mental representation of word meanings has consisted in contrasting different domains of knowledge, broadly reflecting the abstract-concrete dichotomy. More fine-grained semantic distinctions have emerged in neuropsychological and cognitive neuroscience work, reflecting semantic category specificity, but almost exclusively within the concrete domain. Theoretical advances, particularly within the area of embodied cognition, have more recently put forward the idea that distributed neural representations tied to the kinds of experience maintained with the concepts' referents might distinguish conceptual meanings with a high degree of specificity, including those within the abstract domain. Here we report the results of two psycholinguistic rating studies incorporating such theoretical advances with two main objectives: first, to provide empirical evidence of fine-grained distinctions within both the abstract and the concrete semantic domains with respect to relevant psycholinguistic dimensions; second, to develop a carefully controlled linguistic stimulus set that may be used for auditory as well as visual neuroimaging studies focusing on the parametrization of the semantic space beyond the abstract-concrete dichotomy. Ninety-six participants rated a set of 210 sentences across pre-selected concrete (mouth, hand, or leg action-related) and abstract (mental state-, emotion-, mathematics-related) categories, with respect either to different semantic domain-related scales (rating study 1), or to concreteness, familiarity, and context availability (rating study 2). Inferential statistics and correspondence analyses highlighted distinguishing semantic and psycholinguistic traits for each of the pre-selected categories, indicating that a simple abstract-concrete dichotomy is not sufficient to account for the entire semantic variability within either domains
