“…Consistent with prior studies on older drivers (Blanchard et , we did not find systematic over-or under-estimation of self-reported distance across the sample as a whole. In contrast, the four month study on Australian drivers (Molnar et al 2013) found that their sample of older drivers underreported exposure. However, they did not examine if this was consistent across the range of estimates and used correlational rather than concordance statistics.…”

“…Other studies using electronic in-vehicle devices have also found that older drivers had problems accurately estimating how far they relatively small sample sizes (n< 60), short measurement periods (one to two weeks), and the use of devices with limited memory capacity (about 300 hours). Over a longer time frame (4 months), a recent study found that older Australian drivers (n=156) tended to underreport driving exposure (Molnar et al 2013). However, they compared how far participants said they drove in a "normal week" to four months of driving data (averaged to a week), without examining the details of those weeks.…”

Most studies on older adults' driving practices have relied on self-reported information. With technological advances it is now possible to objectively measure the everyday driving of older adults in their own vehicles over time. Objective. The purpose of this study was to examine the ability of older drivers to accurately estimate their kilometers driven over one year relative to objectively measured driving exposure. Methods. A sub-sample (n=159 of 928; 50.9% male) of Candrive II participants (age ≥ 70 years of age) was used in these analyses based on strict criteria for data collected from questionnaires as well as an OttoView-CD Autonomous Data Logging Device installed in their vehicle, over the first year of the prospective cohort study. Results.Although, there was no significant difference overall between the self-reported and objectively measured distance categories, only moderate agreement was found (weighted kappa = 0.57; 95% CI 0.47 to 0.67). Almost half (45.3%) chose the wrong distance category, and some people mis-estimated their distance driven by up to 20,000 km. Those who misjudged in the low mileage group (≤ 5,000 km) consistently under-estimated, while the reverse was found for those in the high distance categories (≥ 20,000), i.e., they always over-estimated their driving distance. Conclusions. Although self-reported driving distance categories may be adequate for studies entailing broad group comparisons, caution should be used in interpreting results. Use of self-reported estimates for individual assessments should be discouraged.

“…Increasingly within the traffic psychology literature, studies are comparing on-road behavioural data obtained from GPS devices with self-reports of one's driving-related behaviour/s (e.g., Albert et al 2014;Blanchard et al 2010;Molnar et al 2013;Huebner et al 2006;Marshall et al 2007). Blanchard et al (2010), for example, reported that GPS devices provided a more reliable measure of the number of driving trips and stops compared with participants' self-reports.…”

Traffic Injury Prevention, 17 (4), 352-358. Young drivers' responses to antispeeding advertisements: Comparison of self-report and objective measures of persuasive processing and outcomes Abstract OBJECTIVE: Self-report measures are typically used to assess the effectiveness of road safety advertisements. However, psychophysiological measures of persuasive processing (i.e., skin conductance response [SCR]) and objective driving measures of persuasive outcomes (i.e., in-vehicle GPS devices) may provide further insights into the effectiveness of these advertisements. This study aimed to explore the persuasive processing and outcomes of two anti-speeding advertisements by incorporating both self-report and objective measures of speeding behaviour. In addition, this study aimed to compare the findings derived from these different measurement approaches. METHODS:Young drivers (N = 20, Mage = 21.01 years) viewed either a positive or negative emotion-based anti-speeding television advertisement. Whilst viewing the advertisement, SCR activity was measured to assess ad-evoked arousal responses. The RoadScout→ GPS device was then installed into participants' vehicles for one week to measure on-road speed-related driving behaviour. Self-report measures assessed persuasive processing (emotional and arousal responses) and actual driving behaviour. RESULTS:There was general correspondence between the self-report measures of arousal and the SCR and between the self-report measure of actual driving behaviour and the objective driving data (as assessed via the GPS devices). CONCLUSIONS:This study provides insights into how psychophysiological and GPS devices could be used as objective measures in conjunction with self-report measures to further understand the persuasive processes and outcomes of emotion-based anti-speeding advertisements.

“…Further scale analysis may clarify the contribution of these items. Third, this study used a measure of self-reported driving self-regulation, whereas it is now feasible to measure this construct objectively (Molnar et al, 2013). However, we suggest that there are still important applications for questionnaire data on driving self-regulation, especially if these measures can be refined and this study makes an important contribution to this achieving this objective.…”
