Abstract(s)
O presente estudo teve como objectivo traduzir e adaptar para Português Europeu cinco
escalas de procrastinação para a população portuguesa, e avaliar as suas características métricas
recorrendo a uma amostra representativa da população portuguesa, por um processo de
amostragem estratificada pelo cruzamento das variáveis Género (2), Grupo Etário (5) e Região
NUTS II (5), proporcionais à distribuição no universo (N=1.034). As escalas avaliadas nas suas
qualidades psicométricas foram a General Procrastination Scale (GPS), a Adult Inventory Procrastination
Scale (AIP), a Decisional Procrastination Scale (DPS), a Irrational Procrastination Scale (IPS) e a Pure
Procrastination Scale (PPS). Os resultados sugerem que as escalas de procrastinação estudadas são
instrumentos fiáveis e válidos para o estudo e mensuração do constructo procrastinação geral, na
população portuguesa. Os dados obtidos são paralelos aos obtidos anteriormente (Svartdal et al.,
2016; Svartdal & Steel, 2017), sugerindo que a Pure Procrastination Scale (Steel, 2010) e a Irrational
Procrastination Scale (Steel, 2010) são medidas superiores dos atributos-chave de procrastinação face
a escalas alternativas. Discutem-se os dados obtidos sugerindo que a possibilidade de fornecerem
valores normativos de procrastinação para a população portuguesa, enriquecem a investigação do
tema em Portugal
ABSTRACT: The present study aimed to translate and adapt into European Portuguese five procrastination scales for the Portuguese population, and to evaluate their metric characteristics using a representative sample of the Portuguese population, through a stratified sampling process by crossing the variables Gender (2), Age Group (5) and NUTS II Region (5), proportional to the distribution in the universe (N=1,034). The scales evaluated in their psychometric qualities were General Procrastination Scale (GPS), Adult Inventory Procrastination Scale (AIP), Decisional Procrastination Scale (DPS), Irrational Procrastination Scale (IPS) and Pure Procrastination Scale (PPS). The results suggest that these procrastination scales are reliable and valid instruments for the study and measurement of general procrastination construct in the Portuguese population. Results obtained parallel those obtained previously (Svartdal et al., 2016; Svartdal & Steel, 2017), suggesting that Pure Procrastination Scale (Steel, 2010) and Irrational Procrastination Scale (Steel, 2010) are superior measures of procrastination core attributes in comparison to alternative scales. Data obtained is discussed, suggesting that the possibility of providing normative values of procrastination for the Portuguese population enriches research on this topic in Portugal.
