The current study aimed at examining a moderated mediation model based on the theoretical framework of organizational socialization. In particular, the mediating effect of organizational career growth (OCG) in the relationship between organizational socialization learning and work outcomes (job satisfaction and performance) was assessed through a multigroup approach on an overall sample of 474 Italian employees. Specifically, structural equation modeling through the bootstrap method was used to test the mediation hypotheses on three dichotomous moderating variables: gender (men/women), parenthood (parents/not parents), and tenure (newcomers/expert employees). Results showed a moderated mediation effect (total mediation) of OCG in the relationship between organizational socialization learning and performance and a mediation effect of OCG in the relationship between organizational socialization learning and job satisfaction. Results are discussed on the light of the original contribution provided, as well as limitations, suggestions for further research and practical implications.
