Abstract(s)
O presente estudo avaliou o valor preditivo da Teoria
da Acção Planeada na intenção de adoptar comportamentos
preventivos para o cancro da pele em indivíduos
saudáveis. Pretendemos identificar quais os preditores
da intenção comportamental quando foram considerados
factores como a representação emocional da
doença e os níveis de optimismo. Os resultados indicaram
que existem diferenças significativas nos componentes
da Teoria da Acção Planeada entre indivíduos
com representações emocionais mais positivas vs. mais
negativas, assim como entre os níveis de optimismo. A
percepção de controlo percebido sobre o comportamento
foi o preditor mais significativo da intenção comportamental
para prevenir o cancro da pele. O nível de
optimismo influencia de forma positiva a intenção comportamental,
contribuindo de forma significativa para
a percepção de controlo sobre o comportamento. Os
resultados indicam ainda que os níveis de optimismo e
a representação emocional da doença desempenham
um papel importante no que se refere à intenção comportamental
para prevenir o cancro da pele e devem
ser considerados quando se desenham intervenções ou
outros tipos de acção para a prevenção do cancro da
pele em indivíduos saudáveis.
The present study assessed the predictive value of the Theory of Planned Behaviour on the intention to adopt preventive measures for skin cancer in healthy individuals. The identification of the predictors of behavioural intention for skin cancer was done after taking into consideration the emotional representation of the disease and the level of dispositional optimism. The results indicated that there are significant differences on the components of the Theory of Planned Behaviour between individuals with positive vs. negative emotional representation of skin cancer, as well as the level of dispositional optimism. Perceived control over the behaviour was found to be the most significant predictor of intention to adopt preventive measures for skin cancer. Dispositional optimism has an important influence on the explained variance on intention, being the perception of perceived behaviour control the most significant predictor. Furthermore, the results also indicate that the emotional representation of skin cancer and dispositional optimism may have an important role for the adoption of preventive measures and should be considered for designing health promotion intervention in healthy individuals.
