Summary

This study investigates the long-term effectiveness of simulator-based education in modifying adult drivers’ risk perception regarding cell phone use while driving. Motivated by the rising prevalence of distracted driving and the need to evaluate whether educational interventions yield lasting behavioral changes, the research extends a previous cross-sectional study conducted in 2014. The primary objective was to determine if a single driving simulator experience could sustain improvements in safety perception over a period of 24–26 months. The methodology involved a longitudinal follow-up of participants from the initial study, which included 100 adult drivers in Hampton, Virginia. Researchers attempted to contact the original cohort via telephone surveys in April and May 2016. Only 27 participants provided valid responses, resulting in a small sample size that limited statistical power. The study lacked a control group, introducing potential internal validity issues such as history and maturation effects. Data analysis compared pre-test safety perception scores with post-test scores from the initial study and re-administered post-test scores from the follow-up. Safety perception was measured using a composite score derived from six variables assessing the perceived safety of various cell phone activities, including texting, emailing, and internet searching. The results indicated that simulator-based education had a statistically significant long-term impact on drivers’ safety perceptions. The average safety perception score decreased from 14.70 (indicating views ranging from unsafe to neutral) before the intervention to 10.37 two years later (indicating views ranging from very unsafe to unsafe). This improvement remained statistically significant (p < 0.002) compared to baseline levels. Approximately 82% of participants maintained or improved their safety perceptions after two years. However, there was a statistically significant deterioration in perception scores compared to the immediate post-intervention results (p < 0.089), suggesting some decay in the educational effect over time. Additionally, 48% of respondents reported that the simulator experience had no impact on their actual driving behavior, though this self-reported lack of impact did not correlate with differences in safety perception scores. None of the demographic, risk, or environmental factors that were significant in the initial study showed statistical significance in the longitudinal analysis, likely due to the small sample size. The study concludes that a single simulator experience can produce durable changes in adult drivers’ risk perception regarding distracted driving, even after two years. Despite some attenuation of the effect and limitations regarding sample size and the absence of a control group, the findings support the use of simulator-based education as a tool for sustaining safety awareness. The results suggest that while perceptions may degrade slightly over time, they do not revert to pre-intervention levels, highlighting the potential longevity of immersive educational interventions in traffic safety campaigns.

Key finding

Drivers' safety perceptions regarding cell phone use remained significantly improved compared to pre-experiment baselines two years after simulator education, although scores significantly declined from immediate post-test levels.
