We update the psychometric properties of the Hypoglycemia Fear Survey-Parents of Young Children (HFS-PYC), a 26-item measure of parents' hypoglycemia fear for young children using an insulin pump.
We combined three similar datasets for the analyses. The data analyzed included parents' responses to the HFS-PYC and a demographic form. For a subset of children (n = 91), we also analyzed self-monitoring of blood glucose data. We used confirmatory factor analysis (CFA) to confirm the measure's original factor structure. Additional analyses examined reliability and validity of a revised HFS-PYC for parents of young children using pumps.
We analyzed data from 116 parents (93% mothers). Mean child age and HbA1c were 5.2 ± 1.3 years and 8.2% ± 1.1%, respectively. CFA identified a 22-item two-factor solution (χ (208, n = 116) = 368.688, P < 0.001, root mean square error of approximation = 0.08, comparative fit index = 0.94, and Tucker-Lewis index = 0.93) with factors corresponding to the original subscales: worry and behavior. The revised subscales demonstrated at least adequate internal consistency (Cronbach's alpha >0.65). Correlations revealed significant negative associations between current HFS-PYC worry scores and children's mean daily blood glucose and percent of very high glucose levels per day, suggesting less fear among parents of young children with elevated glycemic levels. In addition, there was a positive association with the percent of glucose levels in target, suggesting greater hypoglycemia fear among parents of children who have better control.
Results provide preliminary evidence for the reliability and validity of a reduced 22-item HFS-PYC for parents of children using insulin pumps.
我们更新了幼儿低血糖恐惧调查问卷-幼儿家长版（HFS-PYC）的心理测量学特性，这是一项用于评估使用胰岛素泵的幼儿家长低血糖恐惧的包含26个条目的测量工具。
我们合并了三个相似的数据集进行分析。分析的数据包括家长对HFS-PYC的回答以及一份人口统计学表格。对于一部分儿童（n = 91），我们还分析了血糖自我监测数据。我们使用验证性因子分析（CFA）来确认该测量工具的原始因子结构。其他分析检验了修订后的HFS-PYC对使用胰岛素泵的幼儿家长的信度和效度。
我们分析了116名家长（93%为母亲）的数据。儿童的平均年龄和糖化血红蛋白（HbA1c）分别为5.2±1.3岁和8.2%±1.1%。CFA确定了一个包含22个条目的两因子模型（χ(208, n = 116) = 368.688, P < 0.001，近似误差均方根 = 0.08，比较拟合指数 = 0.94，塔克-刘易斯指数 = 0.93），其因子与原始子量表相对应：担忧和行为。修订后的子量表显示出至少足够的内部一致性（克朗巴哈系数>0.65）。相关性分析显示，当前HFS-PYC担忧得分与儿童的平均每日血糖以及每日极高血糖水平的百分比之间存在显著负相关，这表明血糖水平较高的幼儿家长的恐惧程度较低。此外，与目标血糖水平的百分比呈正相关，这表明血糖控制较好的儿童家长对低血糖的恐惧程度更高。
研究结果为简化后的22个条目的HFS-PYC对使用胰岛素泵的儿童家长的信度和效度提供了初步证据。
