Vaccine hesitant parents are linked with re-emergence of vaccine preventable diseases, but evidence is scarce locally. The Parent Attitudes about Childhood Vaccines (PACV) questionnaire was validated and used in the USA to identify vaccine hesitant parents. This study aimed to adapt and translate the 15-item PACV questionnaire from English into the Malay language, and to examine its validity and reliability. The sample population was parents of children aged 0-24 months, recruited at an urban government health clinic between November 2016-June 2017. During content validation, two items from the "Behavior" subdomain were identified as items with formative scale and excluded from exploratory factor analysis (EFA) but retained as part of demography. A total of 151 parents completed the questionnaire with response rate of 93.3%. Test-retest reliability was tested in 25 respondents four weeks later and the intra-class correlation was between 0.53 and 1.00. EFA of the 13 items showed possibility of two to four factor domains, but three domains were most conceptually equivalent. Two of the domains were similar to the original and one factor was identified de novo. One item was deleted due to poor factor loading of < 0.3. Therefore, the validated final PACV-Malay consisted of 12 items framed within three-factor domains. The PACV-Malay was reliable with total Cronbach alpha of 0.77. In conclusion, the PACV-Malay is a valid and reliable tool which can be used to identify vaccine hesitant parents in Malaysia. Confirmatory factor analysis and predictive validity are recommended for future studies.
对疫苗持犹豫态度的父母与疫苗可预防疾病的再次出现有关,但本地证据很少。《儿童疫苗家长态度问卷》(PACV)经过验证并在美国用于识别对疫苗持犹豫态度的家长。本研究旨在将英文版的 15 项 PACV 问卷改编并翻译成马来语,并检验其有效性和可靠性。研究对象为 2016 年 11 月至 2017 年 6 月在城市政府诊所招募的 0-24 个月儿童的家长。在内容验证过程中,“行为”子域中的两个项目被确定为具有形成性量表的项目,并从探索性因素分析(EFA)中排除,但保留作为人口统计学的一部分。共有 151 名家长完成了问卷,应答率为 93.3%。四周后对 25 名受访者进行了重测信度测试,组内相关系数在 0.53 到 1.00 之间。13 项的 EFA 显示可能存在两到四个因素域,但三个域在概念上最等效。两个域与原始的相似,一个新的因子被识别出来。由于因子负荷 < 0.3,有一个项目被删除。因此,验证后的最终 PACV-马来语由包含三个因素域的 12 个项目组成。PACV-马来语具有较高的可靠性,总 Cronbach α 为 0.77。总之,PACV-马来语是一种有效且可靠的工具,可用于识别马来西亚对疫苗持犹豫态度的父母。建议未来的研究进行验证性因素分析和预测有效性。
