To describe symptoms of gastrointestinal distress experienced by healthy, full-term infants in the first 7 months of life and test the psychometric properties of the Infant Gastrointestinal Symptoms Questionnaire (IGSQ).
Parents of infants <7 months (n = 320) completed the IGSQ, the Infant Gastroesophageal Reflux Questionnaire - Revised (I-GERQ-R), and the Neonatal Eating Assessment Tool (NeoEAT) - Breastfeeding and/or Bottle-feeding. Median and percentile scores were calculated for the IGSQ scores for each age group: 0-2, 2-4, 4-6, and 6-7 months. Change in IGSQ scores with age were evaluated using the Kruskal-Wallis test with Mann-Whitney U tests for post-hoc comparisons. Internal consistency reliability was assessed using Cronbach's alpha. Concurrent validity was tested using Spearman's rho between the IGSQ and the I-GERQ-R and NeoEAT.
IGSQ scores decreased significantly with increased infant age, from a median of 28 at 0-2 months to 23 at 6-7 months old. The IGSQ had acceptable internal consistency reliability (Cronbach's alpha = 0.74). IGSQ total score was significantly correlated with I-GERQ-R total score (Spearman's rho (r) = 0.69, p < .001), NeoEAT - Breastfeeding: Gastrointestinal Function subscale score (r = 0.46, p < .001), and NeoEAT - Bottle-feeding: Gastrointestinal Tract Function subscale score (r = 0.47, p < .001).
Gastrointestinal symptoms decrease with increasing age in the first 7 months of life. The IGSQ has evidence of acceptable internal consistency reliability and concurrent validity.
These data can be used to guide IGSQ score interpretation.
描述健康足月婴儿在生命的头 7 个月中经历的胃肠道不适症状，并检验婴儿胃肠道症状问卷（IGSQ）的心理测量特性。
<7 个月的婴儿的父母（n=320）完成了 IGSQ、修订后的婴儿胃食管反流问卷（I-GERQ-R）和新生儿进食评估工具（NeoEAT）-母乳喂养和/或奶瓶喂养。为每个年龄组计算 IGSQ 得分的中位数和百分位数得分：0-2、2-4、4-6 和 6-7 个月。使用 Kruskal-Wallis 检验评估 IGSQ 得分随年龄的变化，并用 Mann-Whitney U 检验进行事后比较。使用 Cronbach's alpha 评估内部一致性可靠性。使用 Spearman's rho 检验 IGSQ 与 I-GERQ-R 和 NeoEAT 之间的同时效度。
IGSQ 评分随婴儿年龄的增加而显著下降，从 0-2 个月时的中位数 28 分降至 6-7 个月时的 23 分。IGSQ 具有可接受的内部一致性可靠性（Cronbach's alpha=0.74）。IGSQ 总分与 I-GERQ-R 总分显著相关（Spearman's rho(r)=0.69，p<.001），与 NeoEAT-母乳喂养：胃肠道功能子量表评分（r=0.46，p<.001）和 NeoEAT-奶瓶喂养：胃肠道功能子量表评分（r=0.47，p<.001）显著相关。
在生命的头 7 个月中，胃肠道症状随年龄的增长而减少。IGSQ 具有可接受的内部一致性可靠性和同时效度的证据。
这些数据可用于指导 IGSQ 评分的解释。
