This paper presents two studies that explore the implications of subjective relational experiences (positive regard, mutuality and vitality) on employee engagement in innovative behaviors at work. Data collected at two points in time were used to test two mediation models that link subjective relational experiences and innovative behaviors. The results of Study 1 indicate that subjective relational experiences directly and indirectly, through affective commitment, are associated with employee engagement in innovative behaviors. The results of Study 2 indicate that subjective relational experiences are positively related to psychological availability, creative self-efficacy, and engagement in innovative behaviors. In addition, the findings of Study 2 indicate that creative self-efficacy fully mediates the relationship between psychological availability and engagement in innovative behaviors, and partially mediates the link between subjective relational experiences and employee engagement in innovative behaviors. The findings of both studies provide further support to the theoretical distinction between psychological state engagement and behavioral engagement at work. (Contains 4 tables and 3 figures.)
