Based on Self-Determination Theory, the present study adopts a helicopter-perspective towards motivating (i.e., autonomy support, structure) and demotivating coaching (i.e., control, chaos). Among five independent samples, consisting of individual and team sport coaches (N = 893; Mage = 37.83 years) and athletes (N = 377; Mage = 17.46 years), Multidimensional Scaling (MDS) analyses were used to examine how a variety of coaching practices reflective of four different coaching styles (i.e., autonomy support, control, structure, and chaos), assessed with a new vignette-based instrument, related to one another.Findings revealed that the (de)motivating practices could be graphically presented within a two-dimensional circumplex, with the horizontal axis representing the level of needsupportive coaching behavior and the vertical axis representing the level of coach directiveness. Moreover, the four coaching styles could be segmented in eight more specific approaches (i.e. clarifying, guiding, attuning, participative, awaiting, abandoning, domineering, and demanding), which formed an ordered sinusoid pattern of correlations, both among each other and in relation to a variety of critical outcomes (e.g. coach need satisfaction, athletes' motivation). It is discussed how a circumplex approach produces both a more integrative and more fine-grained insight regarding (de)motivating coaching behaviour, with resulting implications for practice.
