Dispositional factors enhancing leader–follower relationship's dynamic

Purpose This study investigates dispositional factors' (need for affiliation, positive affectivity and proactive personality) moderation effect on the relationship between leader–follower relationship variables (leader–member exchange and perceived supervisor support) and affective commitment to supervisor. Design/methodology/approach In total, 359 employees in Indonesia participated as the study's respondents. This study employs hierarchical regression analysis to test the hypotheses. Findings The results show that need for affiliation and positive affectivity moderates the relationship between leader–follower relationship variables and affective commitment to supervisor. In addition, all dispositional factors positively influence affective commitment to supervisor as independent variables. This study's findings depict the social exchange theory in practice. Originality/value The present study contributes to theoretical and practical implications. Theoretically, the study extends the knowledge on at least four domains: leader–follower relationship; affective commitment particularly aimed at the supervisor; the roles of dispositional variables on leader–member interactions; and empirically demonstrates social exchange theory. Practically, this study shows which factors are relevant to shaping positive leader–member interactions. Such results are potentially of value for the leader, the organization, and those responsible for recruiting prospective employees.
