Assess validity of the ecSatter Inventory (ecSI) to measure eating competence (EC).
Concurrent administration of ecSI with validated measures of eating behaviors using on-line and paper-pencil formats.
The on-line survey was completed by 370 participants; 462 completed the paper version.
Participants included 863 adults with 832 usable surveys from respondents (mean age 36.2 +/- 13.4 years) without eating disorders, mostly female, white, educated, overweight, physically active, and food secure. Of those indicating intent to complete the on-line survey, 80.3% did so; 54% of mailed surveys were returned.
Eating and food behaviors compared among EC tertiles and between dichotomous EC categories; internal consistency of ecSI.
Analysis of variance, independent t tests, chi-square, factor analysis, logistic regression. Significance level was P < .05.
Mean ecSI score was 31.1 +/- 7.5. ecSI included 4 subscales with internal reliability and content validity. Construct validity was supported by specific behavioral profiles for ecSI tertiles and ecSI dichotomized categories. Persons unsatisfied with weight were 54% less likely to be EC; unit increase in the food like index was associated with nearly 3 times greater likelihood of being EC.
The ecSatter Inventory is a valid measure of EC and can be used for descriptive and outcome measurements.
评估进食能力量表（ecSI）测量进食能力（EC）的有效性。
采用在线和纸笔形式，将ecSI与经过验证的进食行为测量方法同时进行施测。
370名参与者完成了在线调查；462名完成了纸质版调查。
参与者包括863名成年人，共收到832份有效调查问卷（受访者平均年龄36.2±13.4岁），他们均无饮食失调问题，大多为女性、白人、受过教育、超重、身体活跃且粮食安全。在表示打算完成在线调查的人中，80.3%的人完成了调查；邮寄调查问卷的回收率为54%。
比较EC三分位数组之间以及二分EC类别之间的饮食和食物行为；ecSI的内部一致性。
方差分析、独立t检验、卡方检验、因子分析、逻辑回归。显著性水平为P < .05。
ecSI平均得分为31.1±7.5。ecSI包括4个分量表，具有内部信度和内容效度。ecSI三分位数组和二分ec类别组的特定行为特征支持了结构效度。对体重不满意的人具备EC的可能性低54%；食物喜好指数每增加一个单位，具备EC的可能性就增加近3倍。
进食能力量表是一种有效的EC测量工具，可用于描述性测量和结果测量。
