Psychometric tools are increasingly applied during coaching, but little is known about their effects on clients' well-being. We investigated the effects that are evoked when psychometric tools reveal incongruities between career-related values, motives, and skills during career coaching within an early-career sample. Results reveal a negative effect of within-person incongruities on life satisfaction and self-efficacy over time. Further, we compared these effects across different career coaching settings (one-on-one coaching vs. group coaching). Compared to clients in group coaching, clients who received feedback on their incongruities during a one-on-one coaching session experienced a decline in life satisfaction. The results indicate that psychometric tools should carefully be incorporated in career coaching interventions. Further practical and theoretical implications of the findings are discussed.
