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.

评估婴儿期和幼儿期饮食行为的调查工具尚未在太平洋岛民中得到验证，其中儿童肥胖症的患病率正在稳步上升。本研究旨在根据从萨摩亚母婴二元组收集的数据评估婴儿饮食行为问卷 (BEBQ) 和儿童饮食行为问卷 (CEBQ) 的因子结构。BEBQ 在两个时间点进行：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 在产后约 21 个月时进行（平均值 = 21.45 [SD = 1.72]；N = 113)。最初的四因素 BEBQ 和七因素 CEBQ 模型都未能在验证性因素分析中复制。2 个月和 4 个月的 BEBQ 数据表明，通过消除具有低内部可靠性的因素生成的九项双因素模型可以接受拟合。对产后 21 个月的 CEBQ 数据进行的一系列探索性因素分析最终揭示了 16 项三因素结构。BEBQ 和 CEBQ 评分之间几乎没有相关性，这表明断奶前后的婴儿喂养行为没有很强的相关性，或者 BEBQ 和 CEBQ 在横断面而非纵向分析中的功能更好。新推导出的 CEBQ 因素引起了人们对原始 CEBQ 项目和因素在理论上是否足够不同的担忧。研究结果表明，人口和文化差异可能会影响 BEBQ 和 CEBQ 因素结构。需要进一步的定性研究来解决这些问题。
