There is a plethora of literature on barriers to immunizations; however, these studies lack standardization of measurement. The aim of this study was to develop and establish an initial psychometric evaluation of an instrument to measure parental barriers to childhood immunizations. This was a cross-sectional study design. Data analysis included descriptive statistics, reliability estimates, item analysis, and factor analysis. Six hundred and fifty-five participants completed the survey. The Searching for Hardships and Obstacles to Shots instrument was developed with 60 items and reduced to 23 items thorough multiple statistical computations; the best factor model was a three-factor solution (Access to Shots, Concerns About Shots, and Importance of Shots) with a total variance explained of 59.4%. The Cronbach's alpha reliability estimates ranged from .86 to .93, and temporal stability was adequate (r = .85). This study supports exceptional initial psychometric properties of an instrument to measure parental barriers to childhood immunizations.
关于免疫接种障碍的文献极为丰富；然而，这些研究缺乏测量的标准化。本研究的目的是开发并建立一种用于测量家长对儿童免疫接种障碍的工具的初步心理测量评估。这是一项横断面研究设计。数据分析包括描述性统计、信度估计、项目分析和因子分析。655名参与者完成了调查。“寻找疫苗接种的困难和障碍”工具最初有60个项目，经过多次统计计算后缩减至23个项目；最佳因子模型是一个三因子解决方案（获得疫苗接种、对疫苗接种的担忧以及疫苗接种的重要性），解释的总方差为59.4%。克朗巴哈系数信度估计范围为0.86至0.93，时间稳定性良好（r = 0.85）。本研究支持一种用于测量家长对儿童免疫接种障碍的工具具有出色的初步心理测量特性。
