- Autorregulação e consumo de substâncias na adolescênciaPublication . Castillo, José A. García del; Dias, Paulo C.; Castelar-Perim, PauloO objetivo deste estudo é avaliar o papel da autorregulação desenvolvimental na adolescência como fator diferenciador do consumo de tabaco e álcool. Para isso, foi utilizada uma amostra de 407 alunos do Ensino Médio, avaliada com o recurso a um conjunto de questões sobre o consumo destas substâncias e ao Inventário de Autorregulação Adolescente (Moilanen, 2007), um instrumento baseado na teoria desenvolvimental sobre a autorregulação. Os resultados sugerem que a autorregulação é um fator diferenciador entre adolescentes que consomem, ou não, substâncias e a intensidade deste consumo. Adolescentes que consomem tendem a apresentar, consistentemente, pontuações mais baixas na autorregulação a curto e longo-prazo. As limitações e implicações dos resultados são apresentadas e discutidas.
- Preditores do uso do Facebook pelos adolescentes portugueses: contributos de um estudo exploratórioPublication . Dias, Paulo César; Castillo, José António García del; Castillo-López, Álvaro García delA 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.
- Auto-regulação, resiliência e consumo de substâncias na adolescência: contributos da adaptação do questionário reduzido de auto-regulaçãoPublication . Dias, Paulo C.; Castillo, José A. García delNo presente trabalho apresentam-se os estudos de adaptação do Questionário Reduzido de Auto-regulação (Carey, Neal & Collins, 2004), um instrumento que permite a avaliação do Controlo de impulsos e Estabelecimento de objectivos. Na análise das propriedades psicométricas do questionário foi encontradauma estrutura factorial consistente e valores de fidelidade elevados. É estudada a relação entre auto-regulação, resiliência, com o recurso à Escala de Resiliência (Wagnild & Young, 1993), e consumo de substâncias na adolescência. Os resultados sugerem uma relação entre a auto-regulação e o consumo de substâncias, além de uma correlação elevada entre o estabelecimento de objectivos e a resiliência, e uma correlação moderada entre o controlo de impulsos e a resiliência. As implicações do estudo são discutidas.
- Self-regulation and tobacco use: contributes of the confirmatory factor analysis of the Portuguese version of the short self-regulation questionnairePublication . Dias, Paulo; Castillo, José A. Garcia delSelf-regulation has been one of most studied developmental skills, given its close relation with health and lifestyle, adjustment and resilience and in the prevention of risk behaviours as substance use. Given the lack of studies about self-regulation and tobacco use in Portuguese context, this paper aims to present the results of the confirmatory factor analysis of the Short Self-Regulation Questionnaire (Carey, Neal & Collins, 2004) in our population, exploring the role of self-regulation in tobacco use. To do that, the SSRQ and a socio-demographic questionnaire was administered to a sample of 390 adolescents, mostly females (n= 228, 59.2%), with ages ranging from 15 and 18 years old (M= 16.05, SD=. 865). Results allow us to find a good fit model with good reliability of the SSRQ. Descriptive statistics and differential studies allow us to find differences in impulse control according gender and a negative correlation with age. Results allow us also to verify a negative correlation between self-regulation and onset age of tobacco use and a negative correlation between control impulse and tobacco use. Data is analysed according to the literature and its implications to prevention and further researches are presented.
- The Adolescent Self-Regulatory Inventory (ASRI) adaptation to Portuguese contextPublication . Dias, Paulo César; Castillo, José António Garcia del; Moilanen, Kristin L.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.
- The mediating role of self-regulation in cigarette smoking and alcohol use among young peoplePublication . García-del-Castillo, José Antonio; Dias, Paulo César; Díaz-Pérez, Julián; Castillo-López, Álvaro García delThis research explores the role of self-regulation in substance-use behaviours from a developmental perspective. We explore the influence of the peer group and parental competencies on self-regulation, in relation to substance use in young people, by means of two convenience samples, the first comprising 478 participants aged 10 to 20, the majority of whom were female, and the second made up of 311 youngsters aged 10 to 17, the majority being male. The instruments used were a Sociodemographic Questionnaire (ad hoc), a Smoking and Alcohol Use Questionnaire (ad hoc), the Adolescent Self-Regulatory Inventory - brief version (ASRI-2r), the Parental Competencies Scale and the Peer Relations Questionnaire. The results confirm a relationship between gender and long-term self-regulation, whose level is higher among girls and young women. Those youngsters with friends who smoke or regularly drink alcohol score lower on the short-term self-regulation subscales. A moderate positive relationship is confirmed between long-term self-regulation and positive competencies in parents.
- Teacher-student relationship and self-regulated learning in Portuguese compulsory educationPublication . Azevedo, Ângela Sá; Dias, Paulo César; Salgado, Ana; Guimarães, Teresa; Lima, Isabel; Barbosa, AndreiaThe aim of this paper was to explore the relationship between the students' perceptions of teachers' behavior and self-regulated learning in Mathematics. The study, conducted among a group of 625 students of Portuguese Compulsory Education (7th to 9th grades) using the QIPBásic and the IPAAr allowed us to understand differences in the aforementioned variables related with students' gender, age, grades and number of retentions, parents education, professor of Mathematics gender and number of years with the same teacher. The most relevant findings to teaching practice are relate to the positive relation between self-regulated learning and students' perception of their teachers with regard to leadership, helping/friendly, and understanding, as well as the negative relation between self-regulated learning and students' perception of uncertain, dissatisfied and admonishing of their teachers.
