The purpose of this study is to determine whether mentor intervention styles influence benefits gained by novice entrepreneurs through their mentoring relationship. Specifically, this study aims to test the proposal by Gravells (2006) that mentoring is optimized when the mentor exhibits both a maieutic approach and significant involvement in the relationship. The results confirm the proposal by Gravells (2006) to the effect that low directivity combined with a high level of mentor involvement in the relationship is likely to generate greater positive outcomes for the mentee. Conversely, a directive style with a low level of involvement leads to poorer results for the mentee, which also suggests that this type of mentoring relationship may be detrimental.
