Antecedents of Health-Promoting Leadership and Workload as Moderator

Abstract

This study builds on the theory of planned behavior and investigates antecedents of health-promoting leadership behaviors (HPL behaviors): positive health-promoting leadership attitude (HPL attitude) as well as perceived health-promoting leadership norms (perceived HPL norms), and lack of perceived health-promoting leadership behavioral control (perceived HPL behavioral control). Furthermore, based on the conservation of resources theory, these antecedents are conceptualized as personal and job resources with managers’ perceived workload being examined as a moderating boundary condition, suggesting that workload as a job demand facilitates resource loss. A survey was administered to 315 managers. Data were analyzed using hierarchical linear regression analysis and moderation analysis. Results revealed that HPL attitude and perceived HPL norms were positively related to HPL behaviors, whereas a lack of perceived HPL behavioral control was negatively related to HPL behaviors. Furthermore, high workload weakened the relationship between perceived HPL norms and HPL behaviors. Workload did not moderate the relationships between the antecedents HPL attitude and lack of perceived HPL behavioral control, and HPL behaviors. Organizations should offer interventions to foster positive HPL attitude, give managers opportunities for HPL behavioral control, and promote perceived HPL norms. They should acknowledge that high workload may inhibit perceived HPL norms. Intervention approaches with regard to personnel and organizational development for practitioners are discussed. This study contributes to the literature by testing direct antecedents of HPL behaviors. Moreover, this study is the first to test workload as a boundary condition.
