Abstract
The extant literature has identified some variables that are associated with sport coaches' coaching style, like their basic psychological need satisfaction, their motivation for coaching, and their psychological well-being. Framed from a conceptual framework based on Self-Determination Theory applied to sport coaches, the current study explored how sport coaches' basic psychological needs are associated with their motivation (intrinsic vs. external), subjective vitality, and coaching behaviors (autonomy-supporting vs. need-thwarting). Participants were 184 Italian sport coaches (males = 65%, M(age) = 40.22, SD = 11.55, age range 19-74 years) from the "Centro CONI" project. They were requested to fill out online self-report questionnaires assessing the study variables. Structural equation modeling analyses suggested that sport coaches' satisfaction of basic psychological needs was associated with higher levels of intrinsic motivation to train as well as with higher levels of vitality that, in turn, were associated with coaching behaviors supporting athletes' autonomy. Moreover, sport coaches' frustration of basic psychological needs was associated with higher levels of external motivation to train that, in turn, were associated with higher levels of a need-thwarting coaching style. Overall, the findings provided additional support for understanding how sport coaches' basic psychological needs relate to their coaching styles.
