ABSTRACT
The identification of variables which facilitate good quality and quantity sleep represents an important step in tackling the current global sleep loss epidemic. Previous research has established links between good sleep and the positive psychological traits of mindfulness, self-compassion, gratitude and optimism. However, studies have typically focused on single traits, limiting understanding of their collective and independent associations. The two studies reported here address this gap by exploring the combined and unique contributions of mindfulness, self-compassion, gratitude and optimism to sleep; Study 2 further investigated emotion regulation as a common underlying mechanism. Participants in both studies (Study 1 N = 268; Study 2 N = 333) completed online questionnaires assessing the four positive psychological traits and sleep quality and quantity; participants in Study 2 also completed measures of adaptive and maladaptive emotion regulation. Multiple regression analyses revealed that mindfulness, self-compassion, gratitude and optimism collectively accounted for 24.96% (Study 1) and 15.81% (Study 2) of the variance in overall sleep quality and quantity. Optimism and mindfulness emerged as significant linear predictors in their own right, with higher levels of optimism and mindfulness respectively being associated with better sleep. Study 2 further identified maladaptive emotion regulation as a common mediating mechanism. Findings highlight the importance of positive psychological traits in relation to sleep and indicate that optimism and mindfulness might make unique contributions to the prediction of sleep outcomes. Findings also flag emotion regulation as a potential common mediator of associations between positive psychological traits and sleep.
