Dispositional and motivational variables related to the propensity to mentor others and to the provision of career and psychosocial mentoring were examined. Results indicated that prosocial personality variables (other-oriented empathy, helpfulness) related to willingness to mentor others and also accounted for unique variance beyond variables associated with life and career stages. Other-oriented empathy related to actual experience as a mentor. Results also indicated that motives for mentoring others differentially related to psychosocial and career mentoring.
