Study Aims Describe how parents and other private supervisors have responded to the changes made to the Queensland graduated driver licensing system in mid Examine differences in the experiences and perceptions of the parents and non- parents
Method Combination of convenience and snowball sampling Survey administered by the internet Survey conducted between July 2009 and May 2010 Approximately minutes to complete $20 reimbursement for participation
Sample (1) Sample 228 supervisors −116 (50.9%) parents −112 (49.1%) non-parents Age Parents (M = 44.1, sd = 8.6) Non-parents (M = 36.2, sd = 13.1) t (226) = 5.41, p = <.001

Supervisor relationship Relationship to the Learner: −Parents Mother: 34.2% Father: 16.7% –Non-parents Stepmother: 3.1% Stepfather: 2.2% Other: 43.9%
Primary supervisor Were you the primary supervisor for this person? Total: Yes 63.2%, No 36.8% –Parents: Yes 70.7%, No 29.3% –Non-parents: Yes 55.4%, No 44.6% Statistically significant difference: –x 2 (1) = 5.76, p =.02
Number of Learners supervised How many learners have you supervised while they were learning to drive in the past 12 months? Total: M = 1.4 –Parents: M = 1.5 –Non-parents: M = 1.4 Not statistically significant: −t (226) =.50, p =.62
Number of hours of supervision How many hours did you supervise the learner for? Total: M = 79.6 –Parents: M = 68.6 –Non-parents: M = 91.1 Not statistically significant: –t (226) = , p =.06
Parental involvement How involved do you think parents should be in teaching their children to drive? Total: M = 4.0 –Parents: M = 4.1 –Non-parents: M = 3.8 Not statistically significant: –t (226) = , p =.09 1 Not very involved 5 Very involved P NP
Use of the Log book (1) Did you record your supervision time in the log book? Total: M = 1.8 –Parents: M = 1.6 –Non-parents: M = 2.0 Statistically significant: –t (226) = , p = All practice 4 No practice NP P
Use of the Log book (2) How accurate were the hours recorded? Total: M = 3.7 –Parents: M = 3.9 –Non-parents: M = 3.4 Statistically significant: –t (226) = 3.92, p = < Not very accurate 5 Very accurate NP P
Importance of teaching (1) How important do you think it is to teach your learner each of the following?

Discussion (1) Private supervisors provide the majority of the supervised practice that learner drivers undertake in Queensland Parents were more likely to report being the primary supervisor However, non-parents reported providing a substantial amount of supervision Overall, supervisors report that they record hours of practice reasonably accurately
Discussion (2) Both parents and non-parents believe parents should be involved in teaching their children to drive Parents were more likely to report recording the practice they supervised in the logbook, and for the hours to be accurate Overall, non-parents were more likely to think it important to teach a range of safety-related driving behaviours
Study limitations Convenience sample Unable to calculate response rates May be a volunteer bias The representation of parents vs. non- parents may not be generaliseable to the broader population The study relied on self-report data
Conclusions GDL systems have traditionally encouraged the greater involvement of parents Mandating extensive hours of practice has resulted in more private supervision being provided to Learner drivers in Queensland Non-parental supervisors appear to play a significant role, along with parents Need to more directly support private supervisors, including non-parents
Further research Who are the non-parents involved in supervising learners? At what stage do non-parents become involved? Do parents and non-parents provide different types of supervision? Does the parental involvement continue into the provisional phase?
