Survey instruments for assessing eating behaviors in infancy and early childhood have yet to be validated among Pacific Islanders, among whom the prevalence of pediatric obesity is steadily increasing. This study aimed to evaluate Baby Eating Behavior Questionnaire (BEBQ) and Children's Eating Behavior Questionnaire (CEBQ) factor structures against data collected from mother-infant dyads in Samoa. The BEBQ was administered across two time points: approximately 2 months (mean = 2.37 [SD = 0.34]; N = 105) and 4 months postpartum (mean = 4.22 [SD = 0.44]; N = 117). The CEBQ was administered at approximately 21 months postpartum (mean = 21.45 [SD = 1.72]; N = 113). Both the original four-factor BEBQ and seven-factor CEBQ models failed to replicate in confirmatory factor analyses. BEBQ data from 2 and 4 months demonstrated acceptable fit to a nine-item, two factor model, generated by elimination of factors with low internal reliability. A series of exploratory factor analyses on CEBQ data from 21 months postpartum ultimately revealed 16-item, three-factor structure. There was little correlation between BEBQ and CEBQ scores, suggesting either that infant feeding behaviors before and after weaning are not strongly associated, or that the BEBQ and CEBQ function better in cross-sectional, rather than longitudinal analyses. Newly derived CEBQ factors raise concerns regarding whether original CEBQ items and factors were sufficiently theoretically distinct. Study results suggest that demographic and cultural differences may impact both BEBQ and CEBQ factor structure. Further qualitative research is necessary to address these issues.
评估婴儿和幼儿进食行为的调查工具在太平洋岛民中尚未得到验证，而这些人群中儿童肥胖的患病率正在稳步上升。本研究旨在评估婴儿进食行为问卷（BEBQ）和儿童进食行为问卷（CEBQ）的因子结构，以针对萨摩亚母婴对子的数据进行评估。BEBQ 在两个时间点进行评估：大约 2 个月（平均=2.37 [SD=0.34]；N=105）和产后 4 个月（平均=4.22 [SD=0.44]；N=117）。CEBQ 在产后大约 21 个月进行评估（平均=21.45 [SD=1.72]；N=113）。在验证性因子分析中，原始的四因子 BEBQ 和七因子 CEBQ 模型均无法复制。从 2 个月和 4 个月获得的 BEBQ 数据，通过消除内部信度较低的因子，对一个九项、两项因子模型表现出可接受的拟合。对产后 21 个月的 CEBQ 数据进行的一系列探索性因子分析最终揭示了 16 项、三项因子结构。BEBQ 和 CEBQ 评分之间相关性很小，这表明断奶前后婴儿喂养行为之间没有很强的关联，或者 BEBQ 和 CEBQ 在横断面而非纵向分析中效果更好。新得出的 CEBQ 因子引起了人们对原始 CEBQ 项目和因子是否具有足够理论区别的关注。研究结果表明，人口统计学和文化差异可能会影响 BEBQ 和 CEBQ 的因子结构。需要进一步的定性研究来解决这些问题。
