Purpose

This randomized clinical trial tested the efficacy of a 6-week text message program to reduce texting while driving (TWD) for young adults.

Methods

Eligible individuals recruited from four emergency departments from December 2019 to June 2021 were aged 18–25 years who reported TWD in the past 2 weeks. Participants were randomly assigned 1:1 to intervention:assessment control. The intervention arm (n = 57) received an automated interactive text message program, including weekly queries about TWD for 6 weeks with feedback and goal support to promote cessation of TWD. The assessment control arm (n = 55) received identical weekly TWD queries but no additional feedback. Outcomes were collected via web-based self-assessments at 6- and 12 weeks and analyzed under intent-to-treat models, presented as adjusted odds ratios (ORs) with 95% confidence intervals (CIs).

Results

The mean (SD) age was 21.7 (2.1) years, 73 (65%) were female, and 40 (36%) were White. The 6-week follow-up rate was 77.7% (n = 87) and 12-week follow-up rate was 64.3% (n = 72). At 6 weeks, 52.6% (95% CI, 39.0%–66.0%) of intervention participants reported TWD versus 63.6% (95% CI, 49.6%–76.2%) of control participants (adjusted OR, 0.71; 95% CI, 0.32–1.59). At 12 weeks, 38.2% (95% CI, 22.8%–53.5%) of intervention participants reported TWD versus 69.3% (95% CI, 53.8%–84.7%) of control participants (adjusted OR, 0.29; 95% CI, 0.11–0.80).

Discussion

An interactive text message intervention was more effective at reducing self-reported TWD among young adults than assessment control at 12 weeks.

短信干预在目标年轻人中减少开车时发短信的有效性：一项随机对照试验

目的

这项随机临床试验测试了一项为期 6 周的短信计划在减少年轻人开车时发短信 (TWD) 的效果。

方法

2019 年 12 月至 2021 年 6 月从四个急诊科招募的合格人员年龄在 18-25 岁之间，在过去两周内报告了 TWD。参与者被随机分配到 1:1 干预：评估控制。干预组 (n = 57) 收到一个自动交互式短信程序，包括为期 6 周的每周关于 TWD 的查询，并提供反馈和目标支持，以促进停止 TWD。评估控制组 (n = 55) 每周收到相同的 TWD 查询，但没有额外的反馈。在 6 周和 12 周时通过基于网络的自我评估收集结果，并在意向治疗模型下进行分析，以调整后的优势比 (ORs) 和 95% 置信区间 (CIs) 的形式呈现。

结果

平均 (SD) 年龄为 21.7 (2.1) 岁，73 (65%) 为女性，40 (36%) 为白人。6周随访率为77.7%（n = 87），12周随访率为64.3%（n = 72）。在 6 周时，52.6% (95% CI, 39.0%–66.0%) 的干预参与者报告 TWD，而对照组参与者的报告率为 63.6% (95% CI, 49.6%–76.2%)（调整后的 OR，0.71；95% CI，0.32 –1.59)。在 12 周时，38.2% (95% CI, 22.8%–53.5%) 的干预参与者报告了 TWD，而对照组参与者为 69.3% (95% CI, 53.8%–84.7%)（调整后的 OR，0.29；95% CI，0.11 –0.80)。

讨论

与 12 周时的评估控制相比，交互式短信干预在减少年轻人自我报告的 TWD 方面更有效。
