本研究的目的在編製一份精簡並具有良好信效度的健身運動依賴量表,階段一爲發展量表,研究者查詢相關文獻之後建立初步的問卷項目,經由運動心理學教授、諮商心理師以及臨床護理師各一名審閱及修訂問卷之內容效度,並以50名規律運動者預試得到內部一致性係數爲0.89。階段二是測試量表:調查對象包括了163名規律運動者,以因素分析、內部一致性以及項目分析檢定量表。經由因素分析,「健身運動依賴量表」萃取出「情緒困擾」、「活力下降」以及「生理與社會困擾」三個因素,可解釋的總變異量爲64.91%,顯示本量表有良好的建構效度。在信度方面「健身運動依賴量表」總量表及各分量表之Cronbach's α介於0.89~0.74之間,顯示此量表有良好的內部一致性可作爲日後研究者之用。
The purpose of this study was to develop a reliable and valid inventory to measure exercise dependence. In stage one, the authors collected related literatures and made a draft titled ”exercise dependence inventory, EDT” and recruited three exercise, nursing and psychology experts for the review of the content validity. Also, in the first stage, this study randomly sampled 50 regular exercisers to examine its internal consistency of the draft and found Cronbach's α 0.89, indicated initial reliability. In the second stage, this study sampled 163 regular exercisers and administered with ”exercise dependence inventory” Exploratory factor analysis and item analysis extracted 12 items from the inventory and found three factors named ”decreased vigor,” ”mood disturbance,” and ”physical discomforts,” of the EDI, and the accounted variance for the inventory was 64.91%. Further, it was found the Cronbach's α coefficient for three factors were ranging from 0.89-0.74. This study concluded that the newly developed exercise dependence scale, EDT with appropriate validity and reliability, and suggested future study might apply EDT for the exercise dependence research.
