To evaluate the reliability and validity of the Infant Gastrointestinal Symptom Questionnaire (IGSQ), a tool to assess feeding tolerance in infants.
Qualitative methods were used to develop IGSQ content across 5 symptom clusters, yielding a 13-item index of parent-reported infant digestion and elimination behaviors over the prior 7 days. Classical psychometric methods evaluated factor structure, interrater and retest reliability, and validity in 4 prospective studies of 836 infants.
Interrater and retest reliability were acceptable to good. IGSQ Index score was highly correlated (r = 0.89) with daily parent reports. IGSQ scores were significantly different between infants whose parents planned to switch formulas because of perceived feeding problems and those without parental concerns.
The IGSQ is a practical, reliable, and valid method for assessment of infant gastrointestinal-related behaviors. Its use in clinical studies can provide empirical evidence to advance parent education regarding both normal and clinically meaningful feeding-related behaviors.
评估婴儿胃肠道症状问卷(IGSQ)的信度和效度,该问卷是一种评估婴儿喂养耐受性的工具。
采用定性方法编制IGSQ内容,涵盖5个症状群,得出一个13项指标,用于家长报告婴儿在过去7天内的消化和排泄行为。采用经典心理测量方法评估836名婴儿的4项前瞻性研究中的因子结构、评分者间信度和重测信度以及效度。
评分者间信度和重测信度为可接受至良好。IGSQ指标得分与家长每日报告高度相关(r = 0.89)。因感知到喂养问题而计划更换配方奶的婴儿与无家长担忧的婴儿之间,IGSQ得分存在显著差异。
IGSQ是评估婴儿胃肠道相关行为的一种实用、可靠且有效的方法。在临床研究中使用该问卷可为推进家长对正常及具有临床意义的喂养相关行为的教育提供实证依据。
