We examined the relationships of role clarity and organization-based self-esteem with 4 dimensions of commitment to supervisors and organizations (affective, normative, perceived high sacrifice, perceived lack of alternatives) and turnover intentions. Confirmatory factor analyses supported the hypothesized 8-factor model of commitment. Structural equation modeling analyses revealed that role clarity was positively related to affective, normative, and perceived high sacrifice supervisory commitment; while it was not related to organizational commitments. Organization-based self-esteem was positively associated with affective commitment to organizations and supervisors; it was also negatively associated with the lack of alternatives component of supervisory and organizational commitment. Finally, the affective and high-sacrifice dimensions of supervisory commitment related to turnover intentions via parallel forms of organizational commitment.
