自我決定理論在動機研究領域扮演一個非常重要的角色，其理論中也提及基本心理需求包含勝任感、自主性與關係感等必須被滿足，才能讓個體的行為目標與結果，朝較為健全的方向發展。目前針對不同研究領域測量的特殊性已有不同的基本心理需求量表，但運動研究領域則多以一般的基本心理需求量表為測量工具，因此特有的運動基本心理需求量表的發展有其必要性。本研究收集231 位運動員填寫之「基本資料表」、「內在動機量表」及自編的「運動員基本心理需求量表」進行分析，經專家審視、因素分析、內部一致性的考驗過程，符合自我決定理論對基本心理需求包含勝任感、自主性與關係感等結構模式，同時證明其能預測運動員的內在動機，初步說明該量表符合基本心理需求之理論模式，是一份具有信、效度的測量工具。後續研究可以進一步考驗其在理論模式上的配適度，並強化其在運動研究領域的應用價值。

Self-determination theory considered that basic psychological needs had strong connection with intrinsic motivation. It also indicated that the elements of peoples' basic psychological needs including competence, autonomy and relatedness must be fulfilled in order to have better results of behavior quality and mental health during pursuing process. The measurements of basic psychological needs had been developed within different research domains and purposes. However, most of the studies within athletes or sport area used basic psychological measures which were modified from different study areas. This study recruited 231 athletes in varied sports to complete background information, Intrinsic Motivation Scale and new designed Basic Psychological Needs in Sport Scale, BPNSS. Experts' review, exploratory factor analysis and internal consistency test all revealed the BPNSS had structural validity and reliability. Results also revealed that BPNSS could predict athletes' intrinsic motivation. Further studies are needed to establish the theoretical model fit using SEM in order to strengthen the measurement applying valuation.
