This study aimed to develop and validate a tool to measure maternal identity in mothers caring for infants.
This methodological study involved two stages: tool development and evaluation. A preliminary 35-item tool was created and refined to 22 items and administered to 300 mothers with infants. Data were collected between May and June 2024. Descriptive statistics, Pearson correlation, exploratory factor analysis (using Varimax rotation), and confirmatory factor analysis (via AMOS 21.0) were performed. Convergent validity was evaluated using an adapted version of the Maternal Confidence Questionnaire. Internal consistency (Cronbach's α) and split-half reliability (Guttman split) were also assessed.
Exploratory factor analysis identified four sub-factors consisting of 17 items: "warmth type" (seven items), "best effort type" (five items), "indifference type" (three items), and "preparation type" (two items). The content validity index was .86, and construct validity accounted for 59.5% of the variance. Factor loadings ranged from 0.57 to 0.80. Convergent validity was confirmed (r=.70, p<.001). Internal consistency was high, with Cronbach's α values between .85 and .90 and split-half reliability coefficients between .82 and .91. The final tool, named the Maternal Identity Measurement for Mothers with Infants, comprises 17 items rated on a 5-point scale (1-5), with higher scores (possible range, 17-85) indicating a stronger maternal identity.
The developed tool demonstrated strong reliability and validity for assessing maternal identity in mothers of infants. It offers a structured approach for evaluating maternal identity in the context of infant care and has practical implications for maternal health research and interventions.
本研究旨在开发并验证一种用于测量照顾婴儿母亲的母亲身份认同的工具。
本方法学研究包括两个阶段：工具开发和评估。创建了一个初步的包含35个条目的工具，并将其精简为22个条目，然后施用于300名有婴儿的母亲。数据收集于2024年5月至6月之间。进行了描述性统计、Pearson相关性分析、探索性因子分析（使用Varimax旋转）和验证性因子分析（通过AMOS 21.0）。使用改编版的母亲信心问卷评估收敛效度。还评估了内部一致性（Cronbach's α）和分半信度（Guttman分半）。
探索性因子分析确定了由17个条目组成的四个子因子：“温暖型”（7个条目）、“尽力型”（5个条目）、“冷漠型”（3个条目）和“准备型”（2个条目）。内容效度指数为0.８6，结构效度解释了59.5%的方差。因子载荷范围为0.57至0.80。收敛效度得到确认（r = 0.70，p < 0.001）。内部一致性较高，Cronbach's α值在0.85至0.90之间，分半信度系数在0.82至0.91之间。最终工具名为《婴儿母亲的母亲身份测量》，包括17个条目，采用5点量表（1 - 5）评分，得分越高（可能范围为17 - 85）表明母亲身份认同越强。
所开发的工具在评估婴儿母亲的母亲身份认同方面显示出很强的可靠性和有效性。它为在婴儿护理背景下评估母亲身份认同提供了一种结构化方法，对母亲健康研究和干预具有实际意义。
