摘要

背景　肥胖乃熱量囤積之結果，高熱量飲食行為及靜態生活行為都會造成身體熱量囤積。目　的本文目的在於發展與測試兒童熱量儲存行為量表。方法　原始兒童熱量儲存行為量表包含11個問項的高熱量飲食行為，及6個問項的靜態生活行為次量表。共收371個國小兒童為研究對象，資料以驗證性因素分析（confi rmatoryfactor analysis）與已知群組效度（known-group validity）進行量表效度分析；並以內部一致性與再測信度進行量表信度分析。結果　驗證性因素分析結果顯示，兒童熱量儲存行為量表包含高熱量飲食行為（10個問項）及靜態生活行為（4 個問項）兩面向。驗證性因素分析模式指標為卡方值（χ^2）=268.22，自由度（df）=74, p＜.001，規範適配指標（normed fi t index）=.91，非規範適配指標（nonnormedfi t index）=.92，Cronbach's α與再測信度分別為.81及.86。體重過重或肥胖兒的兒童熱量儲存行為量表得分高於體重不足或正常體重者，並達統計上顯著差異（z=3.81, p＜.001）。結論／實務應用　兒童熱量儲存行為量表具良好信效度，應用兒童熱量儲存行為量表，可使健康照護者更全面性的評估兒童熱量儲存相關行為。

Background: Obesity is the consequence of energy retention due to energy-dense food intake (E-intake behavior) and sedentary behavior (S-behavior). Purpose: The purpose of this study was to develop and psychometrically test the Energy Retention Behavior Scale for Children (ERB-C scale). Methods: The ERB-C scale was developed, consisting of an 11-item E-intake behavior subscale and a six-item S-behavior subscale. Confirmatory factor analysis and known-group validity were conducted on 371 children to examine the construct validity of this scale, and internal consistency and test-retest reliability were used to examine its reliability. Results: Confirmatory factor analysis indicates that the ERB-C scale, including its subscales of E-intake behavior (10 items) and S-behavior (four items), fits the data well. The fit indices were as follows: x^2=268.22, df=74, p＜.001, normed fit index=.91, and nonnormed fit index=.92. The Cronbach's α and test-retest reliability of the ERB-C scale were .81 and .86, respectively. The mean ERB-C scale score for overweight/obese children was significantly higher than for underweight/normal-weight children (z=3.81, p＜.001). Conclusions/Implications for Practice: The ERB-Cscale showed satisfactory validity and reliability. This scale may help health professionals comprehensively assess the energy retention behavior of children.
