Mentors' perceptions of negative mentoring experiences: scale development and nomological validation.

Three studies were conducted to develop a psychometrically sound, multidimensional measure of mentors' perceptions of negative experiences with their protégés. In Study 1, items were developed, and content-related validity was established. In Study 2, CFA was used to establish the dimensionality of the new measure. Construct-related (convergent and discriminant) and criterion-related validity evidence were also obtained by using data from matched mentor-protégé dyads. Study 3 replicated the factor structure of the instrument and provided additional validity evidence by using a sample of female academic mentors. The findings are discussed in terms of broadening the scope of mentoring research to consider the mentor's perspective of relationship problems and dyadic processes in mentoring relationships.
