摘要 本研究目的在建構運動目標取向、運動員訓練能力與運動自信心來源之模式，並檢驗此模式之適配度及其關連。以2007年大專籃球聯賽第一、二級晉級複賽之前八強共32隊、383名球員為研究對象。透過研究者自編之「運動目標取向、運動員訓練能力與運動自信心來源量表」進行問卷調查，並以描述統計、因素分析、信度分析、結構方程模式進行資料分析。結論如下：一、本研究所建構之運動自信心來源模式，與樣本資料的適配度達可接受水準。二、運動目標取向對運動員訓練能及運動員自信心來源有正向且直接的關係；運動訓練能力對運動員自信心來源亦有正向且直接的關係。建議教練可以塑造出合適的運動目標情境，來增進運動員訓練能力及運動員自信心來源。

Abstract The main purpose of this study was to construct the goal orientation, athletics’ coachability, and sources of sport-confidence model of collegial basketball union players, and examined goodness of fit and causal relationship of this model. The subjects of this study were 383 basketball player of Collegial Basketball Union (UBA), Division I and Division II Final Eight teams in 2007. Instruments used in this study were “Goal Orientation, Athletics’ Coachability, and Sources of Sport-Confidence Questionnaire.” Descriptive statistics, factor analysis, and Structural Equation Model were used for data analysis. The results showed the model already reached an acceptable level based on the sampled materials. Second, there were significant positive effects of goal orientation, athletics’ coachability on the sources of sport-confidence, and goal orientation on athletics’ coachability in this model. The researcher suggested that the coaches can build favorable sport goal situation in order to improve players’ coachability and the sources of sport-confidence.
