    Coaching has become an important managerial instrument of support. However, there is lack of research on its effectiveness. The authors conducted a quasi-experimental study to figure out whether coaching really leads to presupposed individual goals. Sixty managers of the federal government were divided in two groups: one group followed a coaching program, the other did not. Before the coaching program started (Time 1), self-efficacy beliefs and outcome expectancies were measured, linked to three central domains of functioning: setting one’s own goals, acting in a balanced way and mindful living and working. Four months later (Time 2), the same variables were measured again. Results showed that the coached group scored significantly higher than the control group on two variables: outcome expectancies to act in a balanced way and self-efficacy beliefs to set one’s own goals. Future examination might reveal whether coaching will also be effective among managers who work at different management levels, whether the effects found will be long-lasting, and whether subordinates experience differences in the way their manager functions before and after the coaching.
