The associations between morningness-eveningness, conscientiousness, and religiosity have not been investigated to date. The aim of the present research was to provide evidence for the relationships between these dimensions.
Moreover, we tested whether the well-established link between morningness and life satisfaction could be explained by elevated religiosity of morning-oriented individuals and whether this relationship may be mediated by Conscientiousness. The investigation was conducted on two independent samples of Polish adults (n = 500 and n = 728).
Our results corroborated earlier findings that morningness was positively associated with both Conscientiousness and satisfaction with life. We also found evidence for a statistically-significant positive association between morningness and religiosity.
Moreover, controlling for age and gender, we obtained statistically-significant mediation effects showing that the association between morningness-eveningness and satisfaction with life might stem, at least in part, from the higher religiosity among morning-oriented individuals, also when Conscientiousness was included in the model.
It means that more morning-oriented individuals may benefit from higher psychological well-being thanks to both personality characteristics and attitudes towards religion.
