This study examined the interactive effects of person Corganization (PO) fit and friendship centrality on self-verification perceptions, and the effects of self-verification perceptions on job performance and citizenship behaviors. Based on a sample of 135 employee supervisor pairs and on multilevel analyses, results revealed a positive relationship between PO fit and self-verification perceptions. However, the association between PO fit and self- verification perceptions was facilitated by friendship centrality. Specifically, the relationship between PO fit and self-verification perception was positive and significant when friendship centrality was high, but insignificant when friendship centrality was low. In addition, self-verification perception was positively and significantly associated with job performance and citizenship behaviors toward the organization and coworkers.
