Accurate early assessment and targeted intervention with problematic parent/child feeding dynamics is critical for the prevention and treatment of child obesity. The division of responsibility in feeding (sDOR), articulated by the Satter Feeding Dynamics Model (fdSatter), has been demonstrated clinically as an effective approach to reduce child feeding problems, including those leading to obesity. Lack of a tested instrument to examine adherence to fdSatter stimulated initial construction of the Satter Feeding Dynamics Inventory (fdSI). The aim of this project was to refine the item pool to establish translational validity, making the fdSI suitable for advanced psychometric analysis.
Cognitive interviews (n = 80) with caregivers of varied socioeconomic strata informed revisions that demonstrated face and content validity. fdSI responses were mapped to interviews using an iterative, multi-phase thematic approach to provide an instrument ready for construct validation.
fdSI development required five interview phases over 32 months: Foundational; Refinement; Transitional; Assurance; and Launching. Each phase was associated with item reduction and revision. Thirteen items were removed from the 38-item Foundational phase and seven were revised in the Refinement phase. Revisions, deletions, and additions prompted by Transitional and Assurance phase interviews resulted in the 15-item Launching phase fdSI. Only one Foundational phase item was carried through all development phases, emphasizing the need to test for item comprehension and interpretation before psychometric analyses.
Psychometric studies of item pools without encrypted meanings will facilitate progress toward a tool that accurately detects adherence to sDOR. Ability to measure sDOR will facilitate focus on feeding behaviors associated with reduced risk of childhood obesity.
对有问题的亲子喂养动态进行准确的早期评估和针对性干预对于儿童肥胖的预防和治疗至关重要。由萨特喂养动态模型（fdSatter）阐述的喂养责任划分（sDOR），在临床上已被证明是一种减少儿童喂养问题（包括导致肥胖的问题）的有效方法。缺乏用于检验对fdSatter模型依从性的经过测试的工具促使了萨特喂养动态量表（fdSI）的初步构建。本项目的目的是完善条目库以建立翻译效度，使fdSI适合进行高级心理测量分析。
对不同社会经济阶层的照料者进行了80次认知访谈，这些访谈为修订提供了依据，证明了表面效度和内容效度。使用迭代的多阶段主题方法将fdSI的回答映射到访谈中，以提供一个准备好进行结构效度验证的工具。
fdSI的开发在32个月内需要五个访谈阶段：基础阶段；完善阶段；过渡阶段；确认阶段；和发布阶段。每个阶段都与条目减少和修订相关。在38个条目的基础阶段删除了13个条目，在完善阶段对7个条目进行了修订。过渡阶段和确认阶段访谈引发的修订、删除和添加导致了发布阶段的15个条目的fdSI。只有一个基础阶段的条目贯穿了所有开发阶段，这强调了在进行心理测量分析之前测试条目理解和解释的必要性。
对没有加密含义的条目库进行心理测量研究将有助于开发出一种能够准确检测对sDOR依从性的工具。测量sDOR的能力将有助于关注与降低儿童肥胖风险相关的喂养行为。
