Abstract(s)
O objectivo deste trabalho visa a adaptação e validação da Escala Revista de Orientação para a Vida para
Crianças e Adolescentes Portugueses. O presente estudo incidiu sobre um total de 3195 participantes do
5º e 7º anos de escolaridade. A análise de componentes principais encontrou dois factores, um ligado ao
optimismo e outro que reflecte o pessimismo. Os resultados evidenciados na análise factorial confirmatória
revelam um bom ajustamento da escala. Analisou-se a validade discriminante e concorrente com variáveis
relacionadas com o constructo, nomeadamente: satisfação com o suporte social, auto-estima e qualidade
de vida. O instrumento revela-se adequado na medição da orientação para a vida em populações de
crianças e adolescentes, sendo útil no âmbito da psicologia da saúde.
ABSTRACT: The aim of this study was to adapt and validate the Life Orientation Test, reviewed for children and adolescents. This study included a sample of 3195 participants from the 5th and 7th grades. Through Principal Component Analyses we found two dimensions, one related to optimism and another linked to pessimism. Results in the confirmatory factor analysis showed a good fit model. Additionally, items discriminating validity and concurrent validity were inspected with measures related to optimism, such as, social support satisfaction, self-worth and quality of life. This instrument seems to be adequate for the measurement of life orientation in children and in teenagers, and may be useful in other contexts, such as health psychology.
