Health service psychology has been slow to create a leadership mentoring model. A survey of former chairs of the American Psychological Association of Graduate Students and American Psychological Association's Committee on Early Career Psychologists revealed that: (a) early career leaders had at least one mentor who explicitly supported their leadership development; (b) these mentoring relationships were both formal and informal; (c) peer mentoring was invaluable for fostering success; and (d) mentorship relationships were critical in preparing respondents for their roles. A preliminary framework and associated guidance for leadership mentoring in psychology is proposed.
