11 outcomes (Grossman & Rhodes, 2002; Grossman & Tierney, 1998). These factors have been examined more in the mentoring program evaluation research than in the research done on natural mentors. The duration of the relationship has been found to be important in mentor-mentee matched relationships (Grossman & Rhodes, 2002). Brief (less than 6 months duration) relationships can actually have detrimental effects (Grossman & Rhodes, 2002). Other factors have been less well studied. The frequency and duration of typical contact may also be important to the quality and potential influence of the relationship. The most extensively studied mentoring program, Big Brothers Big Sisters, sets minimum levels of contact between their matched mentors and mentees (Grossman & Tiemey, 1998). Mentors must spend a minimum of 3 to 4 hours with their mentees at least two to four times per month. This program has demonstrated significant positive mental health outcomes for its participants (Grossman & Tiemey, 1998). The final quality factor that was addressed in this study is the amount of trust adolescents have in their mentors and how much they confide in their mentors. These aspects have been considered part of the definition of a mentoring relationship (Rhodes et al., 1992). This includes how much the adolescents tell their mentor about good and/or bad things that happen to them. It also addresses the adolescent's perception of how much this individual influences their behavior. A series of items were developed to operationally define the quality mentoring relationship constructs (Woolard & Greig, 2001). These items included several ordinal response items that assessed the duration of the relationship and the frequency and duration of typical contact. Also, based on previous measures and definitions a Trust/Confiding likert scale was developed (Appendix A; Institute of Behavioral Science,
