“…Not only are questions regarded as a fundamental instrument for controlling and structuring the conversation ( Deplazes, 2016 ; Jautz et al, 2023 ), they also enable coaches to evoke self-reflection processes in clients and thus drive the coaching-immanent change project ( Graf and Spranz-Fogasy, 2018b ; Spranz-Fogasy et al, 2019 ). Schreyögg (2012) therefore names asking questions as the most important task of a coach, while Tracy and Robles (2009 , p. 131) also describe questioning as “one of, if not the, central communicative practice of institutional encounters.” Coaches have a wide repertoire of questioning actions to stimulate self-reflection in clients and thus successfully advance the coaching change project ( Bercelli et al, 2008 ; Muntigl and Zabala, 2008 ; Graf and Spranz-Fogasy, 2018a ; Spranz-Fogasy et al, 2019 ). This transformational power of questioning practices in coaching has been asserted in the practice literature for many years, but there is little empirical research on the change potential of reflection-stimulating techniques used by coaches ( Peräkylä, 2019 ; Graf et al, 2023b ; Fleischhacker and Graf, 2024 ).…”
