Supervised practice driving
| | |
Goodwin, Waller, Foss, Margolis26 | Randomized trial; n = 528 parent-teen dyads recruited during the learner’s permit stage; evaluate effects on supervised practice driving of NETS materials | • No significant treatment group differences |
Chaudhary, Ferguson, Herbel41 | Randomized trial (3 groups); n = 500 parents/group; evaluate effects of NETS and other materials on supervised practice driving and parent management of teen driving after licensure | • High satisfaction with materials • No significant treatment group differences |
Independent driving
| | |
Hartos, Nissen, Simons-Morton42 | Prospective interviews at license with 3 month follow up; n = 47 parent-teen dyads recruited from private driving schools; evaluate the acceptability of the Checkpoints Program | • Families reported liking the agreement |
• Most adopted limits |
– Night |
– Teen passengers |
– High speed roads |
– More limits at follow up than initial intent |
Simons-Morton, Hartos, Beck44,45 | Randomized trial with assessment at license, 1, 4, and 9 months; n = 658 parent-teen dyads; test the efficacy of the Checkpoints Program (video, parent-teen driving agreement, personal admonishment) delivered at time of teen licensure at DMV | With Checkpoints |
• More strict driving limits |
– Night driving → 1 month |
– Passengers and high speed roads → 4 months |
– Overall limits → 9 months |
• Parents 3 times more likely to report adopting and maintaining a parent-teen agreement |
Simons-Morton, Hartos, Leaf, Preusser43 | Randomized trial with assessments at baseline, licensure, 1, 3, 6, and 12 months post-licensure; n = 469 parent-teen dyads recruited at time teen obtained a learner’s permit; evaluate the efficacy of the Checkpoints Program | With Checkpoints |
• More strict driving limits → 12 months |
• Predictors of driving limits |
– Teen and parent expectations (+) |
– Male gender (+) |
– Limits at license (+) |
Simons-Morton, Hartos, Leaf, Preusser46,47 | Randomized trial with assessments at baseline, licensure, 1, 3, 6, and 12 months post license; n = 3743 parent-teen dyads recruited at time of teen permit; test the effectiveness of the Checkpoints Program on teen driving outcomes (recruitment at permit) | With Checkpoints |
• Driving limits (+) |
• Risk perceptions (+) |
• Outcome expectations (+) |
• Expected limits (+) |
• Lower driving outcomes(a) at 12 months and indirect effect through limits(b) |
– Risky driving(a-b) |
– Violations(a-b) |
– Crashes(b) |
