Anticipating individual differences in the strength of these intraindividual associations, we propose dispositional creative self-efficacy (CSE) to serve as a cross-level moderating influence amplifying the day-specific predictive power of autonomy and work engagement for innovative behaviour. Hierarchical linear modelling analyses of the nested data from 123 employees surveyed over 5 consecutive work days suggest that both autonomy and work engagement positively predict self-reported innovative behaviour on a daily basis. Whereas the engagement–innovation link emerges as homogenous across persons, results indicate that the daily within-person effect of autonomy on innovative behaviour varies significantly as a function of CSE such that it is greater for individuals who hold higher rather than lower CSE beliefs. Implications for future research, limitations, and practical implications are discussed.engInnovation, job autonomy, work engagement, creative self-efficacy, diary studyarticle10.1080/1359432X.2017.1332042
