This study assessed the separate and joint effects of having a goal intention and the completeness of implementation intention formation on the likelihood of attending an appointment to obtain vaccination against the hepatitis B virus among men who have sex with men (MSM) in the Netherlands. Extending previous research, it was hypothesized that to be effective in promoting vaccination, implementation intention formation not only requires a strong goal intention, but also complete details specifying when, where and how to make an appointment to obtain hepatitis B virus vaccination among MSM. MSM at risk for hepatitis B virus (N = 616), with strong or weak intentions to obtain hepatitis B virus vaccination, were randomly assigned to form an implementation intention or not. Completeness of implementation intentions was rated and hepatitis B virus uptake was assessed through data linkage with the joint vaccination registry of the collaborating Public Health Services. Having a strong goal intention to obtain hepatitis B virus vaccination and forming an implementation intention, each significantly and independently increased the likelihood of MSM obtaining hepatitis B virus vaccination. In addition, MSM who formed complete implementation intentions were more successful in obtaining vaccination (p < 0.01). The formation of complete implementation intentions was promoted by strong goal intentions (p < 0.01).
本研究评估了目标意向以及实施意向形成的完整性对荷兰男男性行为者（MSM）接种乙型肝炎病毒疫苗预约可能性的单独影响和联合影响。在先前研究的基础上，研究假设为，要有效促进疫苗接种，实施意向的形成不仅需要强烈的目标意向，还需要完整的细节，具体说明MSM何时、何地以及如何预约接种乙型肝炎病毒疫苗。有感染乙型肝炎病毒风险的MSM（N = 616），无论其接种乙型肝炎病毒疫苗的意向强烈与否，均被随机分配以形成或不形成实施意向。对实施意向的完整性进行评分，并通过与合作公共卫生服务机构的联合疫苗接种登记处的数据链接来评估乙型肝炎病毒疫苗的接种情况。有强烈的接种乙型肝炎病毒疫苗的目标意向并形成实施意向，均显著且独立地增加了MSM接种乙型肝炎病毒疫苗的可能性。此外，形成完整实施意向的MSM在获得疫苗接种方面更成功（p < 0.01）。强烈的目标意向促进了完整实施意向的形成（p < 0.01）。
