This study examined the influence of attachment styles and mentoring experiences on willingness to mentor in the future in a formal mentoring program in China. For both mentors and proteges, avoidance and anxiety dimensions of attachment styles and their interaction had a significant influence on willingness to mentor in the future. Mentoring experiences explained unique variance in willingness to mentor beyond attachment styles. Crossover analysis of matched mentor-protege pairs showed that mentoring functions fully mediated the mentor avoidance--protege willingness to mentor relationship. The interaction between protege avoidance and anxiety was directly related to mentor willingness to mentor in the future. Directions for research and implications for managerial practice are provided. (Contains 3 tables and 2 figures.)
