Being a youth mentor is popular among college students, yet little is known about how their initial characteristics are related to mentoring satisfaction. Survey data from college women enrolled in a youth mentoring program (n = 158) and a comparison group (n = 136) were analyzed to determine how initial characteristics of youth mentors (a) differ from comparisons and (b) are associated with mentors' satisfaction. Mentors reported higher autonomy, cultural sensitivity, and lower depression pre-participation than the comparison group, and their pre-participation GPA, cognitive empathy, and depression predicted post-participation mentoring satisfaction. Implications for mentor training are discussed.
