The Relationship Between Employees’ Daily Sleep Quality And Creativity

Drawing from depletion model of self-control,this study examined the influence of employees’ daily sleep quality on their creativity through affective commitment.In addition,the cross-level moderation effect of employees ’ conscientiousness(first moderation stage)and work uncertainty experiences(second moderation stage)are also been examined.This study collected data from 116 employees in 5 working days using empirical sampling method,and tested the proposed moderated-mediation model.The results show that(1)employees’ daily sleep quality is positively related to affective commitment,and then employees’ daily affective commitment is positively related to their creativity;(2)employees’ daily affective commitment mediates the positive relationship between sleep quality and creativity;(3)employees’ conscientiousness makes a cross-level negative moderation effect on the relationship between daily sleep quality and affective commitment.That is,compared with high level of conscientiousness,low level of conscientiousness strengthen the more positive relationship between employees’ daily sleep quality and affective commitment;work uncertainty also makes a cross-level negative moderation effect on the relationship between daily affective commitment and creativity.That is,compared with high level of work uncertainty,low level of work uncertainty strengthen the more positive effect of employees’ daily affective commitment on creativity;(4)employees’ conscientiousness(first moderation stage)and work uncertainty(second moderation stage)jointly make cross-level negative moderation effect on the effect of daily sleep quality on creativity through affective commitment.Compared with other conditions,when employees’ conscientiousness and work uncertainty are both low level,the mediation effect of affective commitment is stronger.Finally,we discussed the theoretical and practical implication of this study.
