AbstractThe purpose of this study was to investigate the relationship between need-supportive
coaching behaviour, self-efficacy, subjective task value, goal orientation and
engagement among Chinese high school football players, and the mediating role of selfefficacy,
subjective task value, and goal orientation in the relationship between needsupportive
coaching behaviour and athlete engagement, to better understand the
determinants and mechanisms of athlete engagement. Participants were 385 Chinese
high school football players (228 boys; 157 girls; Mage = 16.07 years; SD = 1.15; range
= 14-19 years) on 20 teams from 45 high schools using a proportional stratified random
sampling method. They completed a set of previously validated questionnaires,
including the Interpersonal Behaviours Questionnaire (IBQ), Self-efficacy
Questionnaire for Soccer (SEQ-S), Subjective Task Value (STV), The Task and Ego
Orientations Questionnaire (TEOSQ) and Athlete Engagement Questionnaire (AEQ).
