JAMA Netw Open. <\/em>2024;7(7):e2420218. doi:10.1001\/jamanetworkopen.2024.20218<\/h3>\n\n\n\n

<\/a>Key Points<\/p>\n\n\n\n

Question<\/strong>  Can behavioral interventions decrease handheld cell phone\u2013based driver distraction?<\/p>\n\n\n\n

Findings<\/strong>  In this randomized clinical trial with 2020 participating auto insurance customers, the median baseline level of handheld phone while driving was 216 seconds per hour. Those randomized to interventions combining social comparison feedback and financial incentives reduced their handheld phone use while driving by 15% to 21% relative to the control group.<\/p>\n\n\n\n

Meaning<\/strong>  The findings of this study suggest that auto insurers could incorporate these interventions into behavior-based insurance plans and potentially reduce distracted driving at scale and therefore crash risk in the population.<\/a><\/p>\n\n\n\n

Abstract<\/p>\n\n\n\n

Importance<\/strong>  Handheld phone use while driving is a major factor in vehicle crashes. Scalable interventions are needed to encourage drivers not to use their phones.<\/p>\n\n\n\n

Objective<\/strong>  To test whether interventions involving social comparison feedback and\/or financial incentives can reduce drivers\u2019 handheld phone use.<\/p>\n\n\n\n

Design, Setting, and Participants<\/strong>  In a randomized clinical trial, interventions were administered nationwide in the US via a mobile application in the context of a usage-based insurance program (Snapshot Mobile application). Customers were eligible to be invited to participate in the study if enrolled in the usage-based insurance program for 30 to 70 days. The study was conducted from May 13 to June 30, 2019. Analysis was completed December 22, 2023.<\/p>\n\n\n\n

Interventions<\/strong>  Participants were randomly assigned to 1 of 6 trial arms for a 7-week intervention period: (1) control; (2) feedback, with weekly push notification about their handheld phone use compared with that of similar others; (3) standard incentive, with a maximum $50 award at the end of the intervention based on how their handheld phone use compared with similar others; (4) standard incentive\u2009plus\u2009feedback, combining interventions of arms 2 and 3; (5) reframed incentive\u2009plus feedback, with a maximum $7.15 award each week, framed as participant\u2019s to lose; and (6) doubled reframed incentive plus feedback, a maximum $14.29 weekly loss-framed award.<\/p>\n\n\n\n

Main Outcome and Measure<\/strong>  Proportion of drive time engaged in handheld phone use in seconds per hour (s\/h) of driving. Analyses were conducted with the intention-to-treat approach.<\/p>\n\n\n\n

Results<\/strong>\u00a0\u00a0Of 17\u202f663 customers invited by email to participate, 2109 opted in and were randomized. A total of 2020 drivers finished the intervention period (68.0% female; median age, 30 [IQR, 25-39] years). Median baseline handheld phone use was 216 (IQR, 72-480) s\/h. Relative to control, feedback and standard incentive participants did not reduce their handheld phone use. Standard incentive plus feedback participants reduced their use by \u221238 (95% CI, \u221269 to \u22128) s\/h (P<\/em>\u2009=\u2009.045); reframed incentive plus feedback participants reduced their use by \u221256 (95% CI, \u221287 to \u221226) s\/h (P<\/em>\u2009<\u2009.001); and doubled reframed incentive plus feedback participants reduced their use by \u221242 s\/h (95% CI, \u221272 to \u221213 s\/h;\u00a0P<\/em>\u2009=\u2009.007). The 5 active treatment arms did not differ significantly from each other.<\/p>\n\n\n\n

Conclusions and Relevance<\/strong>  In this randomized clinical trial, providing social comparison feedback plus incentives reduced handheld phone use while individuals were driving.<\/p>\n\n\n\n
