Este estudo pretende analisar a relação entre o Cronótipo Individual e o Desempenho
Individual, assim como o efeito moderador da Personalidade e do Work Engagement.
Na amostra constam 130 participantes, com idade entre os 19 e os 65 anos. Para
avaliar as variáveis foram utilizados o Morningness-Eveningness Questionnaire de 5 itens
(Adan & Almirall, 1991), Task-based Job Performance de 13 itens (Smith, Organ & Near,
1983; Fernandes, 2011), Big Five Inventory de 10 itens (Rammstedt & John, 2007) e ainda
Utrecht Work Engagement Scale de 17 itens (Schaufeli, Bakker & Salanova, 2006).
Na análise do efeito principal, os resultados obtidos revelaram que o Cronótipo
Individual não exerce um impacto significativo no Desempenho Individual, o que levou à
infirmação das hipóteses de investigação.
Posteriormente foi executada uma análise a nível exploratório, que contou com
diferentes dimensões relacionadas significativamente na análise correlacional. Foram
propostos dois modelos alternativos de mediação. Os resultados obtidos evidenciaram um
efeito mediador parcial do Cronótipo Individual na relação entre a Conscienciosidade e o
Vigor. A análise da mediação suscitou evidências de um efeito de mediação do Vigor na
relação entre a Conscienciosidade e o Desempenho Individual. Os testes post hoc confirmam
as evidências do primeiro efeito mediador encontrado, mas infirmam o segundo
This study aims to analyze the relation between Chronotype and Job Performance and the moderating effect of Personality and Work Engagement in this relationship. The sample has 130 subjects, aged 19 to 65 years. In order to measure each variable, were used Morningness-Eveningness Questionnaire 5 item version (Adan & Almirall, 1991), Task-based Job Performance 13 item version (Smith, Organ & Near, 1983; Fernandes, 2011), Big Five Inventory 10 item version (Rammstedt & John, 2007) and Utrecht Work Engagement Scale 17 item version (Schaufeli, Bakker & Salanova, 2006). In the analysis of the main effect, our results show that Chronotype has not a significant impact on Job Performance, which led us to reject our hypotheses. Later a second analysis was conducted on an exploratory level, where were evaluated each dimensions significantly related in correlation analysis. We proposed two alternative mediating models to analyse. The results show that Chronotype exercises a mediating effect on the relation between Conscientiousness and Vigour. Our analysis shows the possibility of a mediating effect of Vigour in the relation between Conscientiousness and Job Performance also. Post hoc tests support the first partial mediating effect, but not the last.
