Predictors of intrinsic motivation behind seat belt use in a country where current use is low

Context: Seatbelt use is a major determinant of a driver's safety on the road. In Turkey and other middle-income countries, seatbelt use is lower than in high-income countries and contributes to the higher burden of road traffic injuries. Assessing factors behind drivers' motivations to wear seat belts can help determine appropriate interventions for specific subpopulations. Objective: To analyze the factors predictive of whether drivers who wear seat belts in Afyonkarahisar and Ankara, Turkey do so because they believe seat belts can save their lives. Methods: As part of the monitoring and evaluation of the Bloomberg Philanthropies Global Road Safety Programme, 817 drivers were randomly recruited in Afyonkarahisar and Ankara, Turkey, to participate in roadside interviews. Logistic regression was run on data from 408 drivers who claimed they always wore seat belts belts. Predictors were driver's city, driver's age group (30 and younger, 31 to 40, and over 40 years), whether at least one passenger was in the car, and an interaction term between age group and whether passengers were in the car. The outcome variable of interest was whether drivers wore seat belts because they believed seat belts can save their lives, referred to in this paper as “selection of Reason 3.” Results: The odds of selecting Reason 3 were 2.45 (95% CI: 1.40–4.31) times higher in Ankara than in Afyonkarahisar, 2.52 (95% CI: 1.38–4.60) and 3.65 (95% CI: 1.92–6.95) times higher for drivers aged 31–40 and drivers over the age of 40 than for drivers 30 years of age and younger, respectively, and 5.89 (95% CI: 2.02–17.23), 7.22 (95% CI: 1.61–32.42), and 0.83 (95% CI: 0.32–2.19) times higher for drivers traveling with passengers who were 30 years of age and younger, between 31 and 40, and over 40 than for drivers traveling without passengers in these age groups, respectively. Conclusion: Drivers with passengers had higher odds of selecting Reason 3, especially younger drivers who are more likely to succumb to peer pressure. Older drivers had higher odds of selecting Reason 3. Peer groups and peer education campaigns may have an impact. Education interventions combined with extrinsic campaigns can be aimed at younger drivers to increase and maintain adherence in the population.
