Among emerging adults who are career indecisive, perfectionism and problematic Internet use (PIU) are underdeveloped areas of inquiry. The authors examined the relationship between perfectionism and PIU to measure their contributions to career indecision. The full model was significant, yielding an R[superscript 2] of 0.46 (p less than 0.0001). PIU accounted for the majority of variance in career indecision (adjusted R[superscript 2] = 0.32). Career indecision was also related to maladaptive but not adaptive perfectionism. Counseling implications are discussed.
