Abstract. This study contributes to process–outcome research in coaching by examining mediating processes, which have received little attention to date. On the basis of a sequential process model of coaching, we assumed that occupational self-efficacy and satisfaction of needs mediate the impact of coaches’ emotional support, encompassing the coach–client relationship and resource activation, on coaching satisfaction. Using several points of measurement over time and taking the nested data structure into account, 52 coaching dyads were analyzed using longitudinal multilevel analyses. The results partly supported our assumptions. Occupational self-efficacy, as well as satisfaction of needs, mediated only the impact of clients’ perceived resource activation on coaching satisfaction. Coaches’ perceived coach–client relationship predicted clients’ assessment of coaching satisfaction, but this effect was not mediated by occupational self-efficacy or satisfaction of needs. The results underscore the importance of activating the clients’ resources to improve coaching effectiveness.


Ressourcenaktivierung beeinflusst Coaching Zufriedenheit mittels beruflicher Selbstwirksamkeit und Bedürfnisbefriedigung

Zusammenfassung. Dieser Artikel trägt zur Prozess–Ergebnisforschung im Coaching bei, indem er Mediationsprozesse untersucht, die bisher wenig Beachtung gefunden haben. Basierend auf einem sequentiellen Coaching Prozessmodell nahmen wir an, dass berufliche Selbstwirksamkeit und Bedürfnisbefriedigung den Einfluss emotionaler Unterstützung durch den Coach, die Coach-Klienten-Beziehung und Ressourcenaktivierung beinhaltet, auf Coachingzufriedenheit vermittelt. Unter Verwendung mehrerer Messpunkte im Zeitverlauf und unter Berücksichtigung der genesteten Datenstruktur wurden 52 Coaching-Dyaden mittels längsschnittlicher Multilevelanalyse analysiert. Die Ergebnisse bestätigten teilweise unsere Hypothesen. Die berufliche Selbstwirksamkeit und die Bedürfnisbefriedigung mediierten nur den Einfluss der wahrgenommenen Ressourcenaktivierung der Klienten auf die Coachingzufriedenheit. Die von den Coaches wahrgenommene Coach-Klienten-Beziehung prognostizierte die Bewertung der Coaching-Zufriedenheit durch die Klienten, aber dieser Effekt wurde nicht durch die berufliche Selbstwirksamkeit oder die Befriedigung der Bedürfnisse vermittelt. Die Ergebnisse unterstreichen die Bedeutung der Aktivierung der Ressourcen der Klienten zur Verbesserung der Coaching-Effektivität.
