Clinician Prompts for Human Papillomavirus Vaccination: A Cluster Randomized Trial.

OBJECTIVE: We assessed the impact of an online intervention using clinician prompts for human papillomavirus (HPV) vaccination with a cluster randomized controlled trial. METHODS: The randomized trial occurred July 2021-January 2022 in 48 primary care pediatric practices (24 intervention, 24 control) across the US. We trained clinicians via two online learning modules, plus weekly ''quick tips'' delivered via text or email. The training taught practices to implement a staff prompt to the clinician (e.g., printed reminders placed on the keyboard) plus electronic health record (EHR) prompts (if not already done) at well and acute/chronic visits for initial and subsequent HPV vaccination. We assessed missed opportunities for HPV vaccination using logistic regression models accounting for clustering by practice on an intent to treat basis. Surveys assessed facilitators and barriers to using prompts. RESULTS: During the 6-month intervention, missed opportunities for HPV vaccination increased (worsened) in both intervention and control groups. However, at well child care visits, missed opportunities for the initial HPV vaccine increased by 4.5 (95% CI: -9.0%, -0.1%) percentage points less in intervention versus control practices. Change in missed opportunities for subsequent doses at well child care and non-well child care visits did not differ between trial groups. An end-of trial survey found understaffing as a common challenge. CONCLUSIONS: Clinician prompts reduced missed opportunities for HPV vaccination at well child care visits. Understaffing related to the COVID-19 pandemic may have led to worsening missed opportunities for both groups and likely impeded practices in fully implementing changes.

Missed Opportunities for Adolescent Immunizations at Well-Care Visits During the COVID-19 Pandemic.

PURPOSE: The Coronavirus Disease 2019 pandemic disrupted healthcare, but the impact on vaccination missed opportunities (MOs, vaccine-eligible visits without vaccination) is unknown. We evaluated pandemic-related trends in MOs at adolescent well-care visits for three vaccines: human papillomavirus; quadrivalent meningococcal conjugate; and tetanus, diphtheria, and acellular pertussis (Tdap). METHODS: We analyzed electronic health record data from 24 pediatric primary care practices in 13 states from 1/1/2018 to 12/31/2021. Segmented logistic regression estimated risk differences for MOs during the pandemic relative to prepandemic trends. RESULTS: Among 106,605 well-care visits, we observed decreases in MOs prepandemic followed by an increase in MOs during the pandemic for all three vaccines. Relative to prepandemic, MOs increased for human papillomavirus (+15.9%, 95% confidence interval [CI]: 11.7%, 20.1%), meningococcal conjugate (+9.4%, 95% CI: 5.2%, 13.7%), and tetanus, diphtheria, and acellular pertussis (Tdap) (+ 8.2%, 95% CI: 4.3%, 12.1%). DISCUSSION: Increases in vaccine MOs during the pandemic equaled or exceeded pre-pandemic decreases. Reducing MOs in adolescent well-care could raise vaccine coverage.

Feasibility and acceptability of mobile methods to assess home and neighborhood environments related to adolescent sleep.

OBJECTIVE: A growing evidence base suggests home and neighborhood environmental exposures may influence adolescent sleep, but few studies have assessed these relationships using methods that account for time-varying, location-specific exposures, or multiple neighborhood contexts. This study aimed to assess the feasibility and acceptability of using smartphone global positioning system (GPS) tracking and ecological momentary assessment (EMA) to assess time-varying home and neighborhood environmental exposures hypothesized to be associated with adolescent sleep. METHODS: Adolescents aged 15-17 years in Philadelphia completed 7 days of continuous smartphone GPS tracking, which was used to identify daily levels of exposure to geocoded neighborhood factors (eg, crime, green space). Four daily EMA surveys assessed home sleep environment (eg, noise, light), stress, health behaviors, and neighborhood perceptions. Feasibility and acceptability of GPS tracking and EMA were assessed, and distributions of daily environmental exposures were examined. RESULTS: Among 25 teens (mean age 16, 56% male), there was a high level of GPS location data captured (median daily follow-up: 24 hours). Seventy-eight percent of EMA surveys were completed overall. Most participants (96%) reported no privacy concerns related to GPS tracking and minimal burden from EMA surveys. Exposures differed between participants' home neighborhoods and locations visited outside the home neighborhood (eg, higher crime away from home). Sleep environment disruptions were present on 29% of nights (most common: uncomfortable temperature) and were reported by 52% of adolescents. CONCLUSIONS: Results demonstrate the feasibility and acceptability of mobile methods for assessing time-varying home and neighborhood exposures relevant to adolescent sleep for up to 1 week.

Performance Feedback for Human Papillomavirus Vaccination: A Randomized Trial From the American Academy of Pediatrics Pediatric Research in Office Settings Research Network.

OBJECTIVE: To test the hypothesis that a feedback-based intervention would reduce human papillomavirus (HPV) vaccine missed opportunities. METHODS: In a longitudinal cluster randomized controlled trial of 48 pediatric primary care practices, we allocated half the practices to receive a sequential, multicomponent intervention phased over consecutive periods. In a prior trial (period 1), communication skills training reduced missed opportunities for the initial HPV vaccine dose at well visits but not at acute/chronic visits. The current trial (period 2) evaluated the added value of performance feedback to clinicians after communication training. Performance feedback consisted of an introductory training module, weekly electronic "Quick Tips," and 3 individualized performance feedback reports to clinicians. We fit logistic regression models for the primary outcome of HPV vaccination missed opportunities using generalized estimating equations with independence working correlation, accounting for clustering at the practice level. RESULTS: Performance feedback resulted in a 3.4 (95% confidence interval [CI]: -6.8, 0.0) percentage point greater reduction in missed HPV vaccine opportunities for the intervention versus control group during acute/chronic visits for subsequent HPV vaccinations (dose 2 or 3). However, during well visits for HPV vaccination dose #1, intervention practices increased missed opportunities (worsened) by 4.2 (95% CI: 1.0, 7.4) percentage points more than control practices, reducing the prior period 1 improvements and blunting the overall effect of performance feedback. We did not observe differences for the other visit/dose categories. CONCLUSIONS: Performance feedback improved HPV vaccination for one subset of visits (acute/chronic, subsequent HPV vaccinations due), but not for well visits.

Trends in Positive Depression and Suicide Risk Screens in Pediatric Primary Care During COVID-19.

OBJECTIVE: Adolescent mental health concerns increased during COVID-19, but it is unknown whether early increases in depression and suicide risk have been sustained. We examined changes in positive screens for depression and suicide risk in a large pediatric primary care network through May 2022. METHODS: Using an observational repeated cross-sectional design, we examined changes in depression and suicide risk during the pandemic using electronic health record data from adolescents. Segmented logistic regression was used to estimate risk differences (RD) for positive depression and suicide risk screens during the early pandemic (June 2020-May 2021) and late pandemic (June 2021-May 2022) relative to before the pandemic (March 2018-February 2020). Models adjusted for seasonality and standard errors accounted for clustering by practice. RESULTS: Among 222,668 visits for 115,627 adolescents (mean age 15.7, 50% female), the risk of positive depression and suicide risk screens increased during the early pandemic period relative to the prepandemic period (RD, 3.8%; 95% CI, 2.9, 4.8; RD, 2.8%; 95% CI, 1.7, 3.8). Risk of depression returned to baseline during the late pandemic period, while suicide risk remained slightly elevated (RD, 0.7%; 95% CI, -0.4, 1.7; RD, 1.8%; 95% CI, 0.9%, 2.7%). CONCLUSIONS: During the early months of the pandemic, there was an increase in positive depression and suicide risk screens, which later returned to prepandemic levels for depression but not suicide risk. Results suggest that pediatricians should continue to prioritize screening adolescents for depressive symptoms and suicide risk and connect them to treatment.

Neighborhood Greenspace and Changes in Pediatric Obesity During COVID-19.

INTRODUCTION: Pediatric obesity rates increased during the COVID-19 pandemic. This study examined the associations of neighborhood greenspace with changes in pediatric obesity during the pandemic. METHODS: Electronic health record data from a large pediatric primary care network were extracted to create a retrospective cohort of patients aged 2-17 years with a visit in each of 2 periods: June 2019-December 2019 (before pandemic) and June 2020-December 2020 (pandemic). Multivariable longitudinal generalized estimating equations Poisson regression estimated the associations of census tract‒level Normalized Difference Vegetation Index with (1) changes in obesity risk during the pandemic and (2) risk of new-onset obesity among children who were not obese prepandemic. Analyses were conducted between November 2021 and May 2022. RESULTS: Among 81,418 children (mean age: 8.4 years, 18% Black), the percentage of children who were obese increased by 3.2% during the pandemic. Children in Normalized Difference Vegetation Index Quartiles 2-4 had smaller increases in obesity risk during the pandemic than those in Quartile 1 (risk ratio=0.96, 95% CI=0.93, 0.99; Quartile 3 risk ratio=0.95; 95% CI=0.91, 0.98; Quartile 4 risk ratio=0.95, 95% CI=0.92, 0.99). Among the subset who were not obese before the pandemic, children in Normalized Difference Vegetation Index quartiles 3-4 had a lower risk of new-onset obesity during the pandemic (Quartile 3 risk ratio=0.82, 95% CI=0.71, 0.95; Quartile 4 risk ratio=0.73, 95% CI=0.62, 0.85). Higher Normalized Difference Vegetation Index was associated with smaller increases in obesity risk and lower risk of new-onset obesity among children in urban and suburban areas, but results were in the opposite direction for children in rural areas. CONCLUSIONS: Children living in greener neighborhoods experienced smaller increases in obesity during the pandemic than children in less green neighborhoods, although findings differed by urbanicity.

Associations Between Food Insecurity and Neighborhood Safety, Social Cohesion, Social Control, and Crime Among Mothers of Preschool-Aged Children.

Food insecurity has myriad associations with poor health, and low-income communities have higher than average prevalence of food insecurity. Living in a supportive neighborhood social environment may protect against food insecurity, while adverse neighborhood social conditions, such as crime, may increase the likelihood of food insecurity. To examine associations between food insecurity and neighborhood social factors among families with young children, we administered a cross-sectional survey to 300 mothers and female caregivers of Medicaid-enrolled two- to four-year-old children in Philadelphia. We used multivariable regression to examine associations between food insecurity and perceived neighborhood safety, social cohesion, informal social control, and crime, adjusted for demographics, socioeconomic status, and neighborhood characteristics. Lower food insecurity prevalence was associated with higher perceived neighborhood safety and social cohesion, and lower police-recorded violent crime rates. Future work to increase food security among low-income households may benefit from targeting the neighborhood social environment.

Association of Neighborhood Social Context and Perceived Stress Among Mothers of Young Children.

BACKGROUND: Chronic parental stress may negatively impact health among both parents and children. Adverse neighborhood social conditions like crime may increase stress while a supportive neighborhood may buffer stress and promote well-being. Our objective was to examine associations between neighborhood social factors and stress among mothers of young children. METHODS: We surveyed 300 mothers/female caregivers of Medicaid-enrolled 2 to 4-year-old children in Philadelphia. Maternal stress was measured via the 10-item Perceived Stress Scale (range 0-40). Mothers' perceived neighborhood safety and collective efficacy were assessed using validated scales. Addresses were geocoded to link census tract-level violent crime rates. We used multivariable linear regression to examine associations of neighborhood safety, collective efficacy, and crime with maternal stress, adjusted for demographics, household socioeconomic status, and neighborhood poverty. RESULTS: Among mothers (mean age 31, 60% Black/African American), higher perceived neighborhood safety and collective efficacy were associated with lower stress scores after adjustment for covariates. Each 1-point increase (on a 5-point scale) in perceived neighborhood safety was associated with a 2.30-point decrease in maternal stress (95% CI: -3.07, -1.53). Similarly, each 1-point increase in perceived collective efficacy was associated with a 3.08-point decrease in maternal stress (95% CI: -4.13, -2.02). Police-recorded violent crime rates were not associated with maternal stress. CONCLUSION: Mothers of young children who perceive their neighborhood social environment more favorably report less stress compared to those who feel their neighborhood environment is less safe and cohesive. Future work is warranted to investigate whether interventions that increase perceived neighborhood safety and collective efficacy reduce stress.

Associations of Neighborhood Safety and Collective Efficacy with Dietary Intake among Preschool-Aged Children and Mothers.

Background: Positive neighborhood environments may promote healthier behaviors, yet few studies have examined associations between neighborhood social environment and diet. We examined associations of neighborhood perceived safety, collective efficacy, and violent crime with dietary intake among preschool-aged children and their mothers. Methods: We administered a cross-sectional survey to 300 mothers/female caregivers of Medicaid-enrolled 2- to 4-year-old children in Philadelphia. Mothers reported their own and their child's dietary intake using the validated Dietary Screener Questionnaire. Mixed-effects linear regression models assessed associations of perceived neighborhood safety, collective efficacy, and census tract-level violent crime with parent and child dietary intake, adjusted for individual, family, and neighborhood covariates. Results: Among mothers, higher perceived neighborhood safety and collective efficacy were associated with higher daily intake of fruits/vegetables (ß = 0.35 cups, 95% CI: 0.12-0.58 and ß = 0.30 cups, 95% CI: 0.08-0.52, comparing the highest with lowest tertile). Higher neighborhood-perceived safety was also associated with higher whole-grain intake among mothers (ß = 0.14 ounces, 95% CI: 0.02-0.27) and children (ß = 0.07 ounces, 95% CI: 0.01-0.13, comparing the highest with lowest tertile). Neighborhood social exposures were not associated with intake of added sugars or sugar-sweetened beverages for mothers or children, nor were lower levels of violent crime associated with any outcome. Conclusions: More favorable perceptions of neighborhood safety and collective efficacy were associated with a slightly higher consumption of some healthy foods among mothers and their young children. Future prospective research is needed to confirm these findings, explore potential mechanisms, and determine whether intervening on the social environment improves diet.

COVID-19 and Adolescent Depression and Suicide Risk Screening Outcomes.

BACKGROUND: Mental health concerns increased during the coronavirus disease 2019 pandemic, but previous studies have not examined depression screening in pediatric primary care. We aimed to describe changes in screening, depressive symptoms, and suicide risk among adolescents during the coronavirus disease 2019 pandemic. METHODS: In a repeat cross-sectional analysis of electronic health record data from a large pediatric primary care network, we compared the percentage of primary care visits where adolescents aged 12 to 21 were screened for depression, screened positive for depressive symptoms, or screened positive for suicide risk between June and December 2019 (prepandemic) and June and December 2020 (pandemic). Changes were examined overall, by month, and by sex, race and ethnicity, insurance type, and income. Modified Poisson regression was used to calculate prevalence ratios (PRs) for the prepandemic to pandemic changes. RESULTS: Depression screening at primary care visits declined from 77.6% to 75.8% during the pandemic period (PR: 0.98, 95% confidence interval [CI]: 0.90-1.06). The percentage of adolescents screening positive for depressive symptoms increased from 5.0% to 6.2% (PR: 1.24, 95% CI: 1.15-1.34), with greater increases among female, non-Hispanic Black, and non-Hispanic white adolescents. Positive suicide risk screens increased from 6.1% to 7.1% (PR: 1.16, 95% CI: 1.08-1.26), with a 34% relative increase in reporting recent suicidal thoughts among female adolescents (PR: 1.34, 95% CI: 1.18-1.52). CONCLUSIONS: Results suggest that depression and suicide concerns have increased during the pandemic, especially among female adolescents. Results underscore the importance of consistent depression and suicidality screening.

Effect of Training Pediatric Clinicians in Human Papillomavirus Communication Strategies on Human Papillomavirus Vaccination Rates: A Cluster Randomized Clinical Trial.

Importance: Missed opportunities for human papillomavirus (HPV) vaccination during pediatric health care visits are common. Objectives: To evaluate the effect of online communication training for clinicians on missed opportunities for HPV vaccination rates overall and at well-child care (WCC) visits and visits for acute or chronic illness (hereafter referred to as acute or chronic visits) and on adolescent HPV vaccination rates. Design, Setting, and Participants: From December 26, 2018, to July 30, 2019, a longitudinal cluster randomized clinical trial allocated practices to communication training vs standard of care in staggered 6-month periods. A total of 48 primary care pediatric practices in 19 states were recruited from the American Academy of Pediatrics Pediatric Research in Office Settings network. Participants were clinicians in intervention practices. Outcomes were evaluated for all 11- to 17-year-old adolescents attending 24 intervention practices (188 clinicians) and 24 control practices (177 clinicians). Analyses were as randomized and performed on an intent-to-treat basis, accounting for clustering by practice. Interventions: Three sequential online educational modules were developed to help participating clinicians communicate with parents about the HPV vaccine. Weekly text messages were sent to participating clinicians to reinforce learning. Statisticians were blinded to group assignment. Main Outcomes and Measures: Main outcomes were missed opportunities for HPV vaccination overall and for HPV vaccine initiation and subsequent doses at WCC and acute or chronic visits (visit-level outcome). Secondary outcomes were HPV vaccination rates (person-level outcome). Outcomes were compared during the intervention vs baseline. Results: Altogether, 122 of 188 clinicians in intervention practices participated; of these, 120, 119, and 116 clinicians completed training modules 1, 2, and 3, respectively. During the intervention period, 29 206 adolescents (14 664 girls [50.2%]; mean [SD] age, 14.2 [2.0] years) made 15 888 WCC and 28 123 acute or chronic visits to intervention practices; 33 914 adolescents (17 069 girls [50.3%]; mean [SD] age, 14.2 [2.0] years) made 17 910 WCC and 35 281 acute or chronic visits to control practices. Intervention practices reduced missed opportunities overall by 2.4 percentage points (-2.4%; 95% CI, -3.5% to -1.2%) more than controls. Intervention practices reduced missed opportunities for vaccine initiation during WCC visits by 6.8 percentage points (-6.8%; 95% CI, -9.7% to -3.9%) more than controls. The intervention had no effect on missed opportunities for subsequent doses of the HPV vaccine or at acute or chronic visits. Adolescents in intervention practices had a 3.4-percentage point (95% CI, 0.6%-6.2%) greater improvement in HPV vaccine initiation compared with adolescents in control practices. Conclusions and Relevance: This scalable, online communication training increased HPV vaccination, particularly HPV vaccine initiation at WCC visits. Results support dissemination of this intervention. Trial Registration: ClinicalTrials.gov Identifier: NCT03599557.

Pediatrician Delivered Smoking Cessation Messages for Parents: A Latent Class Approach to Behavioral Phenotyping.

OBJECTIVE: Message framing can be leveraged to motivate adult smokers to quit, but its value for parents in pediatric settings is unknown. Understanding parents' preferences for smoking cessation messages may help clinicians tailor interventions to increase quitting. METHODS: We conducted a discrete choice experiment in which parent smokers of pediatric patients rated the relative importance of 26 messages designed to increase smoking cessation treatment. Messages varied on who the message featured (child, parent, and family), whether the message was gain- or loss-framed (emphasizing benefits of engaging or costs of failing to engage in treatment), and the specific outcome included (eg, general health, cancer, respiratory illnesses, and financial impact). Participants included 180 parent smokers at 4 pediatric primary care sites. We used latent class analysis of message ratings to identify groups of parents with similar preferences. Multinomial logistic regression described child and parent characteristics associated with group membership. RESULTS: We identified 3 groups of parents with similar preferences for messages: Group 1 prioritized the impact of smoking on the child (n = 92, 51%), Group 2 favored gain-framed messages (n = 63, 35%), and Group 3 preferred messages emphasizing the financial impact of smoking (n = 25, 14%). Parents in Group 2 were more likely to have limited health literacy and have a child over age 6 and with asthma, compared to Group 1. CONCLUSIONS: We identified 3 groups of parent smokers with different message preferences. This work may inform testing of tailored smoking cessation messages to different parent groups, a form of behavioral phenotyping supporting motivational precision medicine.

Parent Preferences for Pediatric Clinician Messaging to Promote Smoking Cessation Treatment.

BACKGROUND AND OBJECTIVES: Insights from behavioral economics suggests that the effectiveness of health messages depends on how a message is framed. Parent preferences for smoking cessation messaging has not been studied in pediatrics, warranting further exploration to maximize benefit. We sought to assess parents' perceptions regarding the relative importance of distinct message framings to promote their smoking cessation. METHODS: We conducted a cross-sectional discrete choice experiment in which parent smokers rated the relative importance of 26 messages designed to encourage them to begin cessation treatment. Messages varied on who was featured (child, parent, or family), whether the message was gain or loss framed, and what outcome was included (general health, cancer, respiratory illnesses, child becoming a smoker, or financial impact). The participants were 180 parent smokers attending primary care visits with their children at 4 diverse pediatric sites. The main outcome was the importance of smoking cessation messages based on who was featured, gain or loss framing, and the outcome emphasized. RESULTS: Parent smokers highly prioritized cessation messages emphasizing the impact of quitting smoking on their child versus parent or family. Messages focusing on respiratory illness, cancer, or general health outcomes consistently ranked highest, whereas messages focused on the financial benefits of quitting ranked lowest. Gain versus loss framing did not meaningfully influence rankings. CONCLUSIONS: Parent smokers identified smoking cessation messages that emphasized the impact on their child, with outcomes focused on respiratory health, cancer, or general health, as most important. The clinical impact of these messages should be tested in future research.

Near crash characteristics among risky drivers using the SHRP2 naturalistic driving study.

PROBLEM: Previous research have focused extensively on crashes, however near crashes provide additional data on driver errors leading to critical events as well as evasive maneuvers employed to avoid crashes. The Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study contains extensive data on real world driving and offers a reliable methodology to study near crashes. The current study utilized the SHRP2 database to compare the rate and characteristics associated with near crashes among risky drivers. METHODS: A subset from the SHRP2 database consisting of 4,818 near crashes for teen (16-19 yrs), young adult (20-24 yrs), adult (35-54 yrs), and older (70+ yrs) drivers was used. Near crashes were classified into seven incident types: rear-end, road departure, intersection, head-on, side-swipe, pedestrian/cyclist, and animal. Near crash rates, incident type, secondary tasks, and evasive maneuvers were compared across age groups. For rear-end near crashes, near crash severity, max deceleration, and time-to-collision at braking were compared across age. RESULTS: Near crash rates significantly decreased with increasing age (p < 0.05). Young drivers exhibited greater rear-end (p < 0.05) and road departure (p < 0.05) near crashes compared to adult and older drivers. Intersection near crashes were the most common incident type among older drivers. Evasive maneuver type did not significantly vary across age groups. Near crashes exhibited a longer time-to-collision at braking (p < 0.01) compared to crashes. SUMMARY: These data demonstrate increased total near crash rates among young drivers relative to adult and older drivers. Prevalence of specific near crash types also differed across age groups. Timely execution of evasive maneuvers was a distinguishing factor between crashes or near crashes. Practical Applications: These data can be used to develop more targeted driver training programs and help OEMs optimize ADAS to address the most common errors exhibited by risky drivers.

Advanced driver assistance systems for teen drivers: A national survey of teen and parent perceptions.

OBJECTIVE: Recently developed advanced driver assistance systems (ADAS) have the potential to compensate for teen driving errors and reduce overall crash risk. To date, very limited research has been conducted on the suitability of ADAS for teen drivers-the population most likely to benefit from such systems. The opportunity for ADAS to reduce the frequency and severity of crashes involving teen drivers is hindered when there is a lack of trust, acceptance, and use of those technologies. Therefore, there is a need to study teen and parent perceptions of ADAS to help identify and overcome any potential barriers to ADAS use. METHODS: A U.S. national survey was developed based on themes from previously conducted teen and parent ADAS focus groups. Survey topics included trust in ADAS, effect of ADAS on teen driver safety and driving behavior, effect of ADAS on skill development, data privacy, and cybersecurity. Responses included 5-point Likert scales and open-ended questions. The survey was managed through an online respondent panel by ResearchNow. Eligibility criteria included licensed teens (16-19 years) and parents of licensed teens. Teen and parent responses were compared using chi-square statistics in SAS 9.4. RESULTS: Two thousand and three (teens = 1,000; parents = 1,003) respondents qualified for and completed the survey between September 1 and September 20, 2017. Overall, teens (72%) and parents (61%) felt that ADAS would have a positive impact on transportation. However, teens were more likely to exhibit a positive outlook on ADAS, whereas parents were more likely to have a negative outlook (P < .01). Teens felt that ADAS would be useful during bad weather or drowsy driving but were less concerned than parents about ADAS intervention during their own risky driving (P < .01). The majority of teens (65%) and parents (71%) agreed that teens should learn to drive on vehicles without ADAS, with parents being more likely to agree than teens (P < .01). Parents (55%) were more likely than teens (47%) to be concerned about insurance companies keeping track of teen driving data (P < .01). Most respondents exhibited some concern of ADAS being susceptible to hacking (57%). CONCLUSIONS: This study represents the first effort to quantify ADAS perceptions among teen drivers and their parents at the U.S. national level. These data highlight potential barriers to ADAS use among teen drivers, including a relative disinterest among teens for ADAS intervention during risky driving as well as concerns among both teens and parents that ADAS will inhibit skill development. These survey findings will help inform educational programs to accelerate fleet turnover and provide the foundation for ADAS optimization and evaluation studies among sociodemographic groups.

Advanced driver assistance systems for teen drivers: Teen and parent impressions, perceived need, and intervention preferences.

OBJECTIVE: From the advent of airbags to electronic stability control, technological advances introduced into automobile design have significantly reduced injury and death from motor vehicle crashes. These advances are especially pertinent among teen drivers, a population whose leading cause of death is motor vehicle crashes. Recently developed advanced driver assistance systems (ADAS) have the potential to compensate for skill deficits and reduce overall crash risk. Yet, ADAS is only effective if drivers are willing to use it. Limited research has been conducted on the suitability of ADAS for teen drivers. The goal of this study is to identify teen drivers' perceived need for ADAS, receptiveness to in-vehicle technology, and intervention preferences. The long-term goal is to understand public perceptions and barriers to ADAS use and to help determine how these systems must evolve to meet the needs of the riskiest driving populations. METHODS: Three focus groups (N = 24) were conducted with licensed teen drivers aged 16-19 years and 2 focus groups with parents of teen drivers (N = 12). Discussion topics included views on how ADAS might influence driving skills and behaviors; trust in technology; and data privacy. Discussions were transcribed; the team used conventional content analysis and open coding methods to identify 12 coding domains and code transcripts with NVivo 10. Interrater reliability testing showed moderate to high kappa scores. RESULTS: Overall, participants recognized potential benefits of ADAS, including improved safety and crash reduction. Teens suggested that ADAS is still developing and therefore has potential to malfunction. Many teens reported a greater trust in their own driving ability over vehicle technology. They expressed that novice drivers should learn to drive on non-ADAS-equipped cars and that ADAS should be considered a supplemental aid. Many teens felt that overreliance on ADAS may increase distracted driving or risky behaviors among teens. Parents also expressed skepticism for the technology but felt that it would likely be a useful support for teen drivers after the initial learning phase. CONCLUSIONS: This study elicited important end-user viewpoints by exploring the intersection between advanced automobile safety technology and human perception for the particular use case of teen drivers. For example, despite evidence that teens are the highest risk driving population, teens trust their own driving skills and competence more than in-vehicle technology. This understanding will ultimately advance the safety of teen drivers by identifying barriers to effective ADAS use.
