The Study Of The Adult Eating Behavior Evaluation Questionnaire

Purposes1. To develop an evaluated tool for eating behavior of general adult population-Adult eating behavior evaluation questionnaire.2. To explore the theory model for measurement of adult eating behavior.MethodsWe developed the item pool following the questionnaire developing systematic process by reviewing the literature and focus group discussion. After 2 round test and item analysis, we got a draft of adult eating behavior evaluation questionnaire with 57 items. Then we evaluated the reliability and validity of the draft by sampling survey the residents from the different developed level area in Wuhan City and Yichang Country. After item analysis again, we got the final version of adult eating behavior evaluation questionnaire. Then we evaluated the rationality of the adult eating behavior evaluation model with the structural equation model analysis.Results1. We analysis the influence of demography characteristic, social factor, nutrition knowledge and health belief, family and friends, dietary ambience, mood on eating behavior and the special eating behavior: eating disorder, snacking, eating out. The result showed the diversity of eating behavior and the influence factor of eating behavior.2. We got 300 statements about eating behavior. The statements can be sorted into 8 categories, food shopping, mood, eating out, snacking, food preparation, health eating belief, eating habit, the influence of family and society. These categories were subdivided into many sub-categories to reveal more detail of eating behaviors.3. The result of test in general population showed the reliability of thequestionnaires is good (test-retest reliability=0.86; Cronbach α=0.70; Split-half coefficient = 0.69). 11 major factors were extracted and matched basically the questionnaire designed construct. The sum scores of the questionnaire can distinguish the eating behavior of different area groups, different age groups, and different gender groups. The sum scores of the questionnaire and the most of sum scores of subscales is correlated with the daily nutriment intake.4. We got a adult eating behavior evaluation questionnaire with 38 items after revising the questionnaire again and analyses the evaluation model of eating behavior with the structural equation model analysis. The ratio of x2 and df is 3.79. The value of GFI, AGFI, RMR, and RMSEA are 0.8824, 0.8656, 0.0435, and 0.0510.Conclusions1. We should evaluate eating behavior from two aspects, the description of eating behavior and major influence factor.2. It seemed that we can evaluate eating behavior by describing 8 contents, food shopping, mood, eating out, snacking, food preparation, health eating belief, eating habit, the influence of family and society.3. The reliability and validity of the draft adult eating behavior evaluation questionnaire is acceptable. But it still need be revised.4. It is rational that evaluation of the adult eating behavior in 8 aspects, snacking, health eating behavior, convenience, taste preference, the eating discipline, mood influence, eating speed, eating habit.Innovations1. We fist time use questionnaire developing systematic process to develop a reliable and valid adult eating behavior evaluation questionnaire in china.2. We construct a rational Chinese adult eating behavior evaluation model first time.
