To examine the association between the theory of planned behavior (TPB) constructs and Health Sciences students' intentions to receive COVID-19 vaccination. A cross-sectional study was conducted in Saudi Arabia by recruiting Health Sciences students as participants. Using Structural Equation Modeling (SEM), the proposed TPB model was evaluated. The sample of 505 individuals consisted of more males ( = 275; 54.5%) than females and was relatively young (88% were between the ages of 18 and 30). The suggested TPB model explained 78.2% of the variation in intention to get COVID-19 immunization. We found that greater levels of perceived behavioral control (β = 1.58, < .001) and attitude (β = .44, < .001) strongly predicted increased vaccination intentions. The subjective norm construct was not a significant predictor of vaccination intentions (β = 0.06, = .34). The findings of this study indicate that the TPB can be utilized effectively to obtain insight into the factors associated with COVID-19 adherence and help in the development of effective COVID-19 intervention strategies.
为了检验计划行为理论（TPB）结构与健康科学专业学生接种 COVID-19 疫苗意愿之间的关联，我们在沙特阿拉伯开展了一项横断面研究，招募健康科学专业学生作为参与者。我们采用结构方程建模（SEM）对提出的 TPB 模型进行了评估。该研究共纳入了 505 名参与者，其中男性（ = 275；54.5%）多于女性，且参与者较为年轻（88%的参与者年龄在 18 至 30 岁之间）。该研究提出的 TPB 模型可以解释 78.2%的接种意愿变化。研究结果表明，感知行为控制（β = 1.58， < .001）和态度（β = .44， < .001）水平越高，接种意愿越强。主观规范结构不是接种意愿的显著预测因素（β = 0.06， = .34）。本研究结果表明，TPB 可有效用于深入了解与 COVID-19 疫苗接种相关的因素，并有助于制定有效的 COVID-19 干预策略。
