本研究旨在探討運動參與程度、自我效能與身體意象之關係。以桃園市桃園區國小五、六年級學生為研究對象,以「運動自我效能量表」、「國小學童運動參與程度量表」及「國小學童身體意象量表」為問卷調查工具。本研究共發出500份問卷,有效問卷465 份,有效問卷率為93%。回收問卷以統計套裝軟體SPSS18.0中文版,進行迴歸分析、多元迴歸分析等統計方法找出變項間的關係,再以階層迴歸分析探討運動參與程度在運動自我效能對身體意象的預測上是否扮演中介變項的角色,顯著水準定為α =.05。研究結果發現:一、國小高年級學童之運動自我效能可以正向預測身體意象整體構面及各子構面,其中對「體能自我評估與重視程度」的解釋力最高。二、運動參與程度在運動自我效能對身體意象整體預測上有部分中介效果存在;身體意象子構面部分,運動參與程度在運動自我效能對「體能自我評估與重視程度」有部分中介效果存在。
The purpose of the study was to investigate the relationships between exercise participation level, physical self-efficacy and body image. Study subjects were from Taoyuan City, Taoyuan District elementary school fifth and sixth grade students. The participants are assessed with self-report questionnaires that include physical self-efficacy scale, exercise participation level questionnaire and body image scale. The questionnaires were administered to 500 students and 465 valid replies were received. The retrieved data were further statistically analyzed using the Chinese Version SPSS18.0 and then analyzed with simple regression analysis, multiple regression analysis and hierarchical regression analysis to test the hypotheses. Findings were as follow: 1. The "physical self-efficacy" can positively predict body image and sub-facets of body image. Among the facets, "Fitness self-evaluation and emphasis level" is predictably best. 2. The relationship between exercise self-efficacy and body image was partially mediated by exercise participation level. among body image sub-facets, exercise participation level is also a partial mediator between Exercise self-efficacy and "fitness self-evaluation and emphasis level".
