To examine the role of intent and other theory of planned behavior (TPB) constructs in predicting college students' willingness to text while driving (TWD).
This was a cross-sectional study. 243 male and female college students enrolled in the 2013-2014 academic year in the College of Health, Human Services & Nursing completed a survey on TWD.
All races and ethnicities, ≥18 years of age, cell phone owner, and licensed driver.
Over 70% of the sample (n = 243) reported talking on a cell phone and sending and receiving text messages "at least a few times" while driving within the past week. However, only 27% reported being stopped by police. Of these, 22% reported being fined. Within the past 30 days, 26% reported reading or sending TWD and having to slam on the brakes to avoid hitting another car or pedestrian(s) as a result. In all, 47% of the variance in intention to send TWD was accounted for by the full TPB model. Intention, in turn, predicted willingness to TWD. Intention also mediated the relationship between perceived behavioral control and willingness to TWD.
Attitude was found to be the strongest predictor of intention. In addition, intention was found to mediate the relationship of willingness to TWD on perceived behavioral control. These findings highlight potential factors that could be targeted in behavioral change interventions seeking to prevent TWD.
探讨意图及其他计划行为理论（TPB）构念在预测大学生开车时发短信（TWD）意愿方面的作用。
这是一项横断面研究。2013 - 2014学年在健康、人类服务与护理学院就读的243名男女大学生完成了一项关于开车时发短信的调查。
所有种族和民族，年龄≥18岁，手机拥有者，且持有驾照。
超过70%的样本（n = 243）报告在过去一周内开车时“至少偶尔”打电话、收发短信。然而，只有27%的人报告曾被警察拦下。其中，22%的人报告被罚款。在过去30天内，26%的人报告开车时发短信并因此不得不急刹车以避免撞到其他车辆或行人。总体而言，完整的TPB模型解释了47%的开车时发短信意图的方差变异。意图反过来又预测了开车时发短信的意愿。意图还介导了感知行为控制与开车时发短信意愿之间的关系。
态度被发现是意图的最强预测因素。此外，意图被发现介导了开车时发短信意愿与感知行为控制之间的关系。这些发现突出了在旨在预防开车时发短信的行为改变干预中可作为目标的潜在因素。
