Parents' vaccine attitudes influence their decision regarding child vaccination. To date, no study has evaluated the impact of vaccine conspiracy beliefs on human papillomavirus vaccine acceptance. The authors assessed the validity of a Vaccine Conspiracy Beliefs Scale (VCBS) and determined whether this scale was associated with parents' willingness to vaccinate their son with the HPV vaccine.
Canadian parents completed a 24-min online survey in 2014. Measures included socio-demographic variables, HPV knowledge, health care provider recommendation, Conspiracy Mentality Questionnaire (CMQ), the seven-item VCBS, and parents' willingness to vaccinate their son at two price points.
A total of 1427 Canadian parents completed the survey in English (61.2%) or French (38.8%). A Factor Analysis revealed the VCBS is one-dimensional and has high internal consistency (α=0.937). The construct validity of the VCBS was supported by a moderate relationship with the CMQ (r=0.44, p<0.001). Hierarchical regression analyses found the VCBS is negatively related to parents' willingness to vaccinate their son with the HPV vaccine at both price points ('free' or '$300') after controlling for gender, age, household income, education level, HPV knowledge, and health care provider recommendation.
The VCBS is a brief, valid scale that will be useful in further elucidating the correlates of vaccine hesitancy. Future research could use the VCBS to evaluate the impact of vaccine conspiracies beliefs on vaccine uptake and how concerns about vaccination may be challenged and reversed.
父母对疫苗的态度会影响他们关于儿童疫苗接种的决定。迄今为止，尚无研究评估疫苗阴谋论信念对人乳头瘤病毒疫苗接受度的影响。作者评估了疫苗阴谋论信念量表（VCBS）的有效性，并确定该量表是否与父母让儿子接种人乳头瘤病毒疫苗的意愿相关。
2014年，加拿大父母完成了一项时长24分钟的在线调查。测量指标包括社会人口统计学变量、人乳头瘤病毒知识、医疗保健提供者的建议、阴谋心态问卷（CMQ）、七项疫苗阴谋论信念量表（VCBS），以及父母在两个价格点让儿子接种疫苗的意愿。
共有1427名加拿大父母用英语（61.2%）或法语（38.8%）完成了调查。因子分析显示，疫苗阴谋论信念量表是单维的，具有较高的内部一致性（α=0.937）。疫苗阴谋论信念量表与阴谋心态问卷之间存在中度相关性（r=0.44，p<0.001），支持了该量表的结构效度。分层回归分析发现，在控制了性别、年龄、家庭收入、教育水平、人乳头瘤病毒知识和医疗保健提供者的建议后，疫苗阴谋论信念量表与父母在两个价格点（“免费”或“300加元”）让儿子接种人乳头瘤病毒疫苗的意愿呈负相关。
疫苗阴谋论信念量表是一个简短、有效的量表，将有助于进一步阐明疫苗犹豫的相关因素。未来的研究可以使用该量表来评估疫苗阴谋论信念对疫苗接种率的影响，以及如何挑战和扭转对疫苗接种的担忧。
