疫苗接种是缓解2009年流感大流行(PH1N1)的核心组成部分。然而，疫苗接种计划的有效性在很大程度上取决于人群的依从性。我们使用改进的计划行为理论(TBP)研究了一般人群对接种H1N1疫苗的决策。我们进行了一项纵向研究，收集了香港引入H1N1疫苗前后的数据。结构方程模型(SEM)测试了改良的TPB是否具有解释成人接种疫苗的效用。在完成基线和后续调查的896名受试者中，7%(67/896)的受试者报告“很可能/很可能/肯定”接种疫苗(意向)，但两个月后，只有0.8%(7/896)的受试者报告接种过H1N1疫苗。对H1N1病毒风险低的看法(60%)和对疫苗不良影响的担忧(37%)是避免接种H1N1疫苗的主要理由。更大的感知疫苗益处(β = 0.15)、对疫苗副作用的较少担忧(β = −0.20)、更遵守接种疫苗的社会规范(β = 0.39)、预期如果没有接种疫苗会有更高的悔恨(β = 0.47)、感知到更高的疫苗接种自我效能(β = 0.12)和季节性流感疫苗接种史(β = 0.12)与接受PH1N1疫苗的意愿较高相关，这反过来又预测了自我报告的疫苗接种(β = 0.30)。社会规范(β = 0.70)、预期后悔(β = 0.19)和接种意向(β = 0.31)与接种计划变量呈正相关，可解释接种规划变量的70%，进而预测自我报告接种接种(β = 0.36)可解释报告接种行为变量的36%。被认为来自PH1N1的低风险和被认为来自PH1N1疫苗的高风险抑制了PH1N1疫苗的接种。TPB和其他组成部分都有助于预期的疫苗接种，但社会规范和预期遗憾主要与疫苗接种意图和规划有关。疫苗接种计划是决定接种PH1N1疫苗的一个比意向更重要的近期决定因素。意图本身并不是未来疫苗接种量的可靠预测指标。
Vaccination was a core component for mitigating the 2009 influenza pandemic (pH1N1). However, a vaccination program's efficacy largely depends on population compliance. We examined general population decision-making for pH1N1 vaccination using a modified Theory of Planned Behaviour (TBP). We conducted a longitudinal study, collecting data before and after the introduction of pH1N1 vaccine in Hong Kong. Structural equation modeling (SEM) tested if a modified TPB had explanatory utility for vaccine uptake among adults. Among 896 subjects who completed both the baseline and the follow-up surveys, 7% (67/896) reported being “likely/very likely/certain” to be vaccinated (intent) but two months later only 0.8% (7/896) reported having received pH1N1 vaccination. Perception of low risk from pH1N1 (60%) and concerns regarding adverse effects of the vaccine (37%) were primary justifications for avoiding pH1N1 vaccination. Greater perceived vaccine benefits (β = 0.15), less concerns regarding vaccine side-effects (β = −0.20), greater adherence to social norms of vaccination (β = 0.39), anticipated higher regret if not vaccinated (β = 0.47), perceived higher self-efficacy for vaccination (β = 0.12) and history of seasonal influenza vaccination (β = 0.12) were associated with higher intention to receive the pH1N1 vaccine, which in turn predicted self-reported vaccination uptake (β = 0.30). Social norm (β = 0.70), anticipated regret (β = 0.19) and vaccination intention (β = 0.31) were positively associated with, and accounted for 70% of variance in vaccination planning, which, in turn subsequently predicted self-reported vaccination uptake (β = 0.36) accounting for 36% of variance in reported vaccination behaviour. Perceived low risk from pH1N1 and perceived high risk from pH1N1 vaccine inhibited pH1N1 vaccine uptake. Both the TPB and the additional components contributed to intended vaccination uptake but social norms and anticipated regret predominantly associated with vaccination intention and planning. Vaccination planning is a more significant proximal determinant of uptake of pH1N1 vaccine than is intention. Intention alone is an unreliable predictor of future vaccine uptake.
