To develop and provide initial data to validate a contemporary measure of maternal perceptions of infant vulnerability.
Questions that address current concerns of mothers regarding their young children (such as the risk of sudden infant death syndrome) were added to an existing Vulnerable Child Questionnaire. Questions not relevant to either current concerns or to young infants were removed. The modified questionnaire, along with standard measures of maternal anxiety and depressive symptoms, were administered to mothers of 39 healthy full-term babies, 17 mothers of 'medically fragile' babies and 19 mothers of jaundiced babies. Babies were approximately 12 weeks of age at the time of completion of the questionnaire.
Three questions were removed from the questionnaire on the basis of poor item-total correlations, leaving the final version with 10 questions, scored on 1-5 rating scales. Cronbach alpha for the revised scale was 0.7. There was a significant difference (P = 0.002) in mean vulnerable baby scores between the control group and the 'medically fragile' group. There was a moderately strong correlation between vulnerable baby score and maternal state anxiety (r = 0.6) and a weaker correlation with maternal depressive symptoms (r = 0.3).
The modified questionnaire has good internal consistency. The difference in mean scores between the three groups, and correlations with maternal anxiety and depressive symptoms, lend construct validity to the scale. The Vulnerable Baby Scale appears to be suitable for assessing maternal perceptions of the vulnerability of their young babies in clinical and research settings although further research, with larger samples, may be necessary to fully establish the scale's psychometric properties.
开发并提供初始数据以验证一种当代测量母亲对婴儿易感性认知的方法。
将涉及母亲当前对幼儿担忧的问题（如婴儿猝死综合征风险）添加到现有的《脆弱儿童问卷》中。去除与当前担忧或幼儿无关的问题。修改后的问卷，连同母亲焦虑和抑郁症状的标准测量方法，被施用于39名健康足月儿的母亲、17名“医学脆弱”婴儿的母亲和19名黄疸婴儿的母亲。在完成问卷时，婴儿大约12周龄。
基于较差的项目总分相关性，从问卷中删除了三个问题，最终版本保留10个问题，采用1 - 5评分量表计分。修订后量表的克朗巴哈α系数为0.7。对照组和“医学脆弱”组之间的平均脆弱婴儿得分存在显著差异（P = 0.002）。脆弱婴儿得分与母亲状态焦虑之间存在中度强相关性（r = 0.6），与母亲抑郁症状的相关性较弱（r = 0.3）。
修改后的问卷具有良好的内部一致性。三组之间的平均得分差异以及与母亲焦虑和抑郁症状的相关性，为该量表提供了结构效度。《脆弱婴儿量表》似乎适用于在临床和研究环境中评估母亲对其幼儿易感性的认知，尽管可能需要进一步进行更大样本量的研究，以充分确立该量表的心理测量特性。
