A text message delivered smoking cessation intervention: Design and rationale of the Text My Quit Study. Contemp Clin Trials 2019; 81:19-27. [PMID: 30999058 PMCID: PMC6550345 DOI: 10.1016/j.cct.2019.04.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Revised: 04/05/2019] [Accepted: 04/13/2019] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Smoking cessation interventions delivered through mobile technologies offer promise as an effective intervention tool. However, most existing programs have not been empirically tested, were not developed with end-user participation, and/or do not address evidence-based cognitive and behavioral variables shown to enhance smoking cessation in clinical trials. In addition, many programs tested in research trials have required users to access the internet and/or a smartphone app to access all program features, limiting the potential reach of those programs. METHODS/DESIGN This study is a randomized controlled trial testing the efficacy of the TMQ intervention for smoking cessation. All participants are randomly assigned to receive 12 weeks of either; (1) a tailored smoking-cessation intervention delivered 100% through text messaging (TMQ), or (2) non-smoking-related text messages serving as a control for contact and subject burden (Mojo). Assessments are conducted at baseline, 3- and 6-month follow-up. The primary outcome is prolonged abstinence using an intent-to-treat approach. To understand why TMQ may be more effective than Mojo, we will test several posited mechanisms of action (i.e., mediators) that may underlie intervention efficacy and will examine use of the TMQ integrated social support (ISS) network. At the end of treatment, semi-structured interviews will be conducted with TMQ participants. CONCLUSIONS This study will provide a rigorous test of an innovative smoking cessation program delivered 100% through text messages. Use of mixed methodologies will provide the opportunity to enhance our understanding of the user's experience with TMQ and identify areas for future enhancement and/or expansion.

Abstract
Context: Short messaging service (SMS or text messaging) allows for the exchange of electronic text messages. Online chatting refers to Internet-based transmission of messages for real-time conversation. Poison Control Centers (PCCs) in the United States communicate with the public primarily via telephone. However, people increasingly prefer the convenience of SMS and chatting. Our objective is to describe the use of SMS and chatting by PCCs in the United States. Methods: An electronic survey questionnaire was distributed to all 55 US poison control center members of the American Association of Poison Control Centers. The survey assessed protocols for SMS and chatting, inquiry volume, and staff satisfaction. Centers reporting use of SMS or chatting services were administered follow-up questions, which further documented SMS and chatting interfaces and startup and maintenance costs. Descriptive statistics were used to describe the data. No statistical analysis was performed. Results: Of the 55 PCCs, 51 (93%) responded to the survey, 6 (12%) of which currently use or formerly used SMS and/or chatting. Inquiry volume ranged from 0 to 1 per day for SMS and 0 to 20 per day for chats. Startup costs ranged from $0 to $25,000. The most beneficial aspect, reported by 4 of the 6 PCCs (66.6%), was providing an alternative contact for inquiries. Most SMS and chatting interactions were completed within 10 and 30 min, respectively. All six centers completed telephone interactions within 10 min. The most disadvantageous aspects, reported by 2 of the 6 PCCs (33.3%), were staff apprehension and interaction length. Technology, such as syncing with existing call queuing software and databases, presented the greatest barrier to implementation. Conclusions: A minority of PCCs in the United States use SMS and chatting. Further research may investigate the economic feasibility of these systems, if SMS and chatting effectively expands public access, and patient comfort in contacting PCCs.

Abstract
The saturation of mobile phones throughout Australia has led to some individuals being unable to regulate their use within situations that are inappropriate or risky. One of the most prevalent risky mobile phone use behaviours is texting while driving. Attempts to explain texting while driving suggest cognitive variables and personality characteristics are key factors. This study explored relationships between trait self-regulation, habitual text messaging, trait mindfulness, and texting while driving. One hundred and seventy participants comprising Australian undergraduate psychology students and members of the public completed an online survey measuring trait self-regulation, habitual text messaging behaviour, trait mindfulness, and frequency of texting while driving. It was found that habitual texting behaviour mediated the relationship between trait self-regulation and frequency of texting while driving. Additionally, trait mindfulness moderated the relationship between habit and texting while driving, such that habitual texting was significantly, positively related to texting while driving, but only for individuals with low to moderate trait mindfulness. These results suggest personality constructs related to attention, awareness, and control of behaviour play a significant role in counteracting the association that habitual texting behaviour has with the frequency of texting while driving. As these traits are considered malleable, this association may be applicable in future development of intervention programs aimed at increasing control over mobile phone use and reducing the frequency with which people text while driving.

Kidd DG, Chaudhary NK. Changes in the sources of distracted driving among Northern Virginia drivers in 2014 and 2018: A comparison of results from two roadside observation surveys. JOURNAL OF SAFETY RESEARCH 2019; 68:131-138. [PMID: 30876504 DOI: 10.1016/j.jsr.2018.12.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2018] [Revised: 11/13/2018] [Accepted: 12/05/2018] [Indexed: 06/09/2023]
Abstract
INTRODUCTION An increase in distracted driving has been suggested as a factor contributing to the 15% increase in fatal crashes from 2014 to 2016, but objective information about the prevalence of distracted driving in recent years is incomplete or lacking. The current study replicated a 2014 observation study conducted in Northern Virginia to examine whether the prevalence of distracted driving overall and of individual secondary behaviors has changed. METHOD Drivers of moving or stopped vehicles were observed at 12 locations across 4 Northern Virginia communities during the daytime. The presence of 12 different secondary behaviors was recorded. RESULTS In 2018, about 23% of drivers were engaged in at least one secondary behavior, which was not significantly different from 2014. Overall phone use was not significantly different between 2014 and 2018. However, the likelihood of holding a cellphone significantly decreased while the likelihood of manipulating a cellphone significantly increased in 2018 relative to 2014. About 14% of drivers were engaged in noncellphone secondary behaviors in 2014 and 2018, which exceeded the proportion using phones in both years. CONCLUSIONS There was no evidence that distracted driving has become more common in recent years, but the prevalence of some secondary behaviors has changed. Most concerning was the 57% increase in the likelihood of cellphone manipulation in 2018 relative to 2014, a behavior that has been consistently linked to increased crash risk; however, because the behavior is uncommon overall, the increased prevalence would be expected to only slightly increase crash rates. Practical applications: Although cellphone use was frequently observed in 2014 and 2018, collectively, other noncellphone secondary behaviors were more prevalent. Practitioners and policymakers should continue targeting cellphone use, but also must target other common secondary behaviors to fully address distracted driving.

Abstract
Pedestrian injuries injure about 180,000 individuals and kill 6000 each year in the United States, and pedestrian injury rates have increased each of the last several years. Distracted pedestrian behavior may play a role in the trend of increasing risk for pedestrian injury. Using in vivo behavioral coding over the course of two weeks on two urban college campuses, this study aimed to (1) understand the type and rate of distractions engaged in by pedestrians on urban college campuses, and (2) investigate the impact of distraction on street-crossing safety and behavior. A total of 10,543 pedestrians were observed, 90% of them young adults. Over one-third of those pedestrians were distracted while actively crossing roadways. Headphones were the most common distraction (19% of all pedestrians), followed by text-messaging (8%) and talking on the phone (5%). Women were more likely to text and talk on the phone than men, and men were more likely to be wearing headphones. Distracted pedestrians were somewhat less likely to look for traffic when they entered roadways. As handheld device usage continues to increase, behavioral interventions should be developed and implemented. Changes to policy concerning distracted pedestrian behavior, including improvement of the built environment to reduce pedestrian risk, should be considered in busy pedestrian areas like urban college campuses.

Abstract
BACKGROUND An epidemic of pedestrian accidents when walking while texting suggests that people are less aware of their surroundings during distracted walking, and highlights the importance of visual scanning for pedestrian safety. Quantitative examination of visual scanning during distracted walking is still lacking. RESEARCH QUESTION Is visual scanning behavior altered by distracted walking in healthy young adults? METHODS We compared visual scanning behavior in 20 young adults during usual (single-task) walking, walking while performing a letter-fluency task, and walking while texting. Visual scanning behavior was measured by fixation count and dwell time percentage in specific areas of interest. Dual-task effects on gait speed, letter fluency, texting speed and accuracy, and situational awareness were also examined. RESULT Visual scanning behavior differed between the three walking conditions. During dual-task letter fluency, participants had significantly more non-walking path fixations than either of the other two conditions (i.e., more frequent, broader visual scanning). Conversely, during dual-task texting, gaze was focused predominantly on the phone, with little visual scanning of the walking path and surrounding environment. When walking without texting or talking, gaze was directed equally to far walking path and surrounding environment. SIGNIFICANCE Texting while walking is associated with a considerable reduction in overt visual attention to the walking path and surrounding areas. Whether this translates to reduced conscious awareness of environmental stimuli remains unclear. Performing a verbal task while walking was associated with more frequent, wider visual scanning behavior, which may be specific to the nature of the verbal task in this study.

Abstract
OBJECTIVE The present study aims to quantify the effects of texting and driver behavior on the accident risk associated with a sudden event. Further, the study attempts to compare the effects of driving behavior of inexperienced young and professional drivers on risk during predetection and postdetection phases of the event. METHODS Forty-nine drivers from 2 categories-inexperienced young drivers and experienced professional drivers-took part in simulated experiments. The participants drove in a free-flow road environment under 3 driving conditions: no distraction (baseline) and writing short and long texts while driving. The participants were exposed to a sudden hazardous event during each drive. Accident probability during the sudden event was modeled with a generalized linear mixed model (with a logit link function). RESULTS As expected, both texting tasks increased accident risk, and the risk was much higher for inexperienced young drivers than for professional drivers. Time lapsed in reducing speed increased the odds for accident risk significantly. A comparative analysis of the driver categories showed that impairment in driving behavior due to the texting tasks was similar for both groups during the predetection phase. However, the risk associated with the texting tasks was higher for young drivers during the postdetection phase. A possible reason could be that young drivers had 65% and 75% higher approach speeds (than the professional drivers) during the short and long text tasks, respectively. CONCLUSIONS The results provide statistical evidence that increased speed is expressed as increased risk-taking behavior among young drivers, which subsequently is the main reason for their higher accident risk during texting tasks. Moreover, the results confirm that professional drivers are not able to mitigate the increased accident risk associated with texting tasks due to late detection of the event during the tasks.

Abstract
INTRODUCTION The purpose of this study was to examine reasons adolescents give for pretending to text in various social situations. Pretending to text was conceptualized as when a person uses a cellphone to make it look like they are texting, but they are not actually sending messages. Little research is available from the adolescent perspective regarding self-presentation and avoidance when using digital devices in social contexts. METHODS A convergent mixed methods approach was used to understand the experience of high school sophomores, juniors, and seniors (n = 216) in the United States. Chi-square analyses and t-tests were used to examine differences between those who pretended to text and those who did not. Qualitative data were analyzed using van Manen's line-by-line approach. RESULTS & CONCLUSIONS Participants indicated they pretended to text for reasons of avoidance, to maintain a positive appearance, and sometimes to provide a sense of security if they felt unsafe in a situation. This study uses self-presentation to further understand adolescent perceptions of pretending to text.

Abstract
INTRODUCTION Longitudinal integrated clerkships (LICs) are an increasingly popular clerkship model that relies heavily on community-based preceptors. The availability of an engaged and prepared community-based faculty is crucial to the success of these programs. Teachers in these programs are often geographically separate from medical school campuses, are engaged in busy practices, and have limited time to devote to faculty development activities. METHODS We created a series of five brief faculty development podcasts directed towards community-based teachers in LICs from three US medical schools. Topics included encouraging continuity, bedside teaching, encouraging student ownership of patients, communicating and managing patient results between clinic days, and choosing the right patients for continuity. The podcasts were sent via a grouped text message just prior to preceptors' morning commute time. Pre- and postsurveys assessed the acceptability and effectiveness of the podcasts. RESULTS Among the 33 postintervention survey responders, 27 (81.8%) listened to at least three podcasts, 21 (63.6%) found them moderately or very helpful, 23 (69.7%) perceived that the podcasts altered their teaching style, 23 (69.7%) would likely or highly likely listen to further podcasts, and 18 (54.5%) would likely or highly likely recommend the podcasts to colleagues. DISCUSSION In a cohort of multispecialty faculty teaching in LICs, educational podcasts were well received and perceived by preceptors to impact their teaching style. Texting these podcasts to other community-based preceptors may offer an effective strategy for providing faculty development to busy clinicians.

Abstract
Mobile phone distracted driving is a recurrent issue in road safety worldwide. Recent research on driving behaviour of distracted drivers suggests that in certain circumstances drivers seem to assume safer behaviours while using a mobile phone. Despite a high volume of research on this topic, self-regulation by mobile phone distracted drivers is not well understood as many driving simulator experiments are designed to impose an equal level of distraction to participants being tested for their driving performance. The aim of this research was to investigate the relationship between self-regulatory secondary task performance and driving. By a driving simulator experiment in which participants were allowed to perform their secondary tasks whenever they feel appropriate, the driving performance of 35 drivers aged 18-29 years was observed under three phone conditions including non-distraction (no phone use), hands-free interactions and visual-manual interactions in the CARRS-Q advanced driving simulator. Drivers' longitudinal and lateral vehicle control observed across various road traffic conditions were then modelled by Generalized Estimation Equations (GEE) with exchangeable correlation structure accounting for heterogeneity resulting from multiple observations from the same driver. Results show that the extent of engagement in the secondary task influence both longitudinal and lateral control of vehicles. Drivers who engaged in a large number of hands-free interactions are found to select lower driving speed. In contrast, longer visual-manual interactions are found to result in higher driving speed among drivers self-regulating their secondary task. Among the road traffic conditions, drivers distracted by their self-regulated secondary tasks are found to select lower speeds along the s-curve compared to straight and motorway segments. In summary, the applied human-machine system approach suggests that road traffic demands play a vital role in both secondary task management and driving performance.

Abstract
This study applied the Prototype Willingness Model (PWM) to investigate the factors that may predict young drivers' (non-intentional) willingness to text while driving, text while stopped, and engage in high and low levels of speeding. In addition, the study sought to assess whether general optimism bias would predict young drivers' willingness to text and speed over and above the PWM. Licenced drivers (N = 183) aged 17-25 years (M = 19.84, SD = 2.30) in Queensland, Australia completed an online survey. Hierarchical multiple regressions revealed that the PWM was effective in explaining the variance in willingness to perform all four illegal driving behaviours. Particularly, young drivers who possessed favourable attitudes and a positive prototype perception towards these behaviours were more willing to engage in texting and speeding. In contrast to the study's predictions, optimistically biased beliefs decreased young drivers' willingness to text while stopped and engage in high and low levels of speeding. The findings of the study may help inform policy and educational campaigns to better target risky driving behaviours by considering the influence of attitudes, prototypes and the non-intentional pathway that may lead to engagement in texting while driving and stopped and engagement in high and low levels of speeding.

Abstract
Use of mobile phones while driving is known to cause crashes with possible fatalities. Different habits of mobile phone use might be distracting forces and display differential impacts on accident risk; the assessment of the relative importance is relevant to implement prevention, mitigation, and control measures. This study aimed to assess the relationship between the use of mobile phones at population level and road crash fatalities in large urban areas. Data on road crashes with fatalities were collected from seven Italian metropolitan areas and matched in time and space with high resolution mobile phone traffic volume data about calls, texts, Internet connections and upload/download data. A case-crossover study design was applied to estimate the relative risks of road accident for increases in each type of mobile phone traffic volumes in underlying population present in the small areas where accidents occurred. Effect modification was evaluated by weekday/weekend, hour of the day, meteorological conditions, and street densities. Positive associations between road crashes rates and the number of calls, texts, and Internet connections were found, with incremental risks of 17.2% (95% Confidence Interval [CI] 7.7, 27.6), 8.4% (CI 0.7, 16.8), and 54.6% (CI 34.0, 78.5) per increases (at 15 min intervals) of 5 calls/100 people, 3 text/100 people, and 40 connections/100 people, respectively. Small differences across cities were detected. Working days, nighttime and morning hours were associated with greater phone use and more road accidents. The relationship between mobile phone use and road fatalities at population level is strong. Strict controls on cellular phone in the vehicle may results in a large health benefit.

Abstract
Texting during walking has become a very common daily activity and could alter gait performance, especially during locomotion when additional visual attention is demanded, such as obstacle crossing. The purpose of this study was to examine biomechanical changes in obstructed gait characteristics while engaging in a phone texting activity. Gait analyses were performed on ten young healthy adults under the following two tasks: 1) walking and crossing an obstacle set at a 10% of the subject's height and 2) walking and crossing an obstacle while responding to a text message. Whole body motion data were collected with a 10-camera motion capture system. Our data demonstrated that a conservative gait pattern was adopted while performing texting when approaching and crossing over the obstacle, which was indicated by slower walking speeds and greater toe-obstacle clearances. This gait pattern was, however, accompanied by a greater body sway in the frontal plane during crossing, which could be an indication of perturbed gait balance control. Increased visual-attentional demand from a concurrent phone texting could negatively impact young pedestrians' safety during obstacle crossing.

Abstract
INTRODUCTION Teen drivers crash at a much higher rate than adult drivers, with distractions found as a factor in nearly 6 out of 10 moderate-to-severe teen crashes. As the driving environment continues to rapidly evolve, it is important to examine the effect these changes may be having on our youngest and most vulnerable drivers. METHOD The purpose of this study was to identify types of vehicle crashes teens are most frequently involved in, as well as the distracting activities being engaged in leading up to these crashes, with a focus on identifying changes or trends over time. We examined 2,229 naturalistic driving videos involving drivers ages 16-19. These videos captured crashes occurring between 2007 and 2015. The data of interest for this study included crash type, behaviors drivers engaged in leading up to the collision, total duration of time the driver's eyes were off the forward roadway, and duration of the longest glance away from forward. RESULTS Rear-end crashes increased significantly (annual % change=3.23 [2.40-4.05]), corresponding with national data trends. Among cell phone related crashes, a significant shift occurred, from talking/listening to operating/looking (annual % change=4.22 [1.15-7.29]). Among rear-end crashes, there was an increase in the time drivers' eyes were off the road (β=0.1527, P=0.0004) and durations of longest glances away (β=0.1020, P=0.0014). CONCLUSIONS Findings suggest that shifts in the way cell phones are being used, from talking/listening to operating/looking, may be a cause of the increasing number of rear-end crashes for teen drivers. PRACTICAL APPLICATIONS Understanding the role that cell phone use plays in teen driver crashes is extremely important. Knowing how and when teens are engaging in this behavior is the only way effective technologies can be developed for mitigating these crashes.

Abstract
OBJECTIVES The use of mobile device-based electronic social media (ESM) in bed is rapidly becoming commonplace, with potentially adverse impacts on sleep and daytime functioning. The purpose of this study was to determine the extent to which in-bed ESM use is associated with insomnia, daytime sleepiness, mood, and sleep duration in adults. METHODS This was a cross-sectional observational study conducted among 855 hospital employees and university students (mean age, 43.6years; 85% female) via an online questionnaire. RESULTS Nearly 70% of participants indulged in in-bed ESM use, with nearly 15% spending an hour or more a night doing so. The degree of in-bed ESM use did not vary by gender, but higher levels of in-bed ESM use were seen in younger and middle-aged than elderly participants. Compared with participants with no in-bed ESM use and controlling for age, gender, and ethnicity, participants with high in-bed ESM use were more likely to have insomnia, anxiety, and short sleep duration on weeknights, but not depression or daytime sleepiness; low in-bed ESM use only increased the likelihood of short sleep duration on weeknights. In-bed ESM use by a bed partner did not have an adverse association with sleep or mood. CONCLUSIONS In-bed ESM use is associated with sleep and mood dysfunction in adults. These findings are of relevance to clinicians, therapists, and the public at large, as they suggest that limitation of in-bed ESM use is a potential interventional strategy in the overall management of sleep hygiene and mental health.

Everyday multitasking habits: University students seamlessly text and walk on a split-belt treadmill. Gait Posture 2018; 59:168-173. [PMID: 29032000 DOI: 10.1016/j.gaitpost.2017.10.011] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Revised: 10/02/2017] [Accepted: 10/06/2017] [Indexed: 02/02/2023]
Abstract
With increasing numbers of adults owning a cell phone, walking while texting has become common in daily life. Previous research has shown that walking is not entirely automated and when challenged with a secondary task, normal walking patterns are disrupted. This study investigated the effects of texting on the walking patterns of healthy young adults while walking on a split-belt treadmill. Following full adaptation to the split-belt treadmill, thirteen healthy adults (23±3years) walked on a tied-belt and split-belt treadmill, both with and without a simultaneous texting task. Inertial-based movement monitors recorded spatiotemporal components of gait and stability. Measures of spatial and temporal gait symmetry were calculated to compare gait patterns between treadmill (tied-belt and split-belt) and between texting (absent or present) conditions. Typing speed and accuracy were recorded to monitor texting performance. Similar to previous research, the split-belt treadmill caused an alteration to both spatial and temporal aspects of gait, but not to time spent in dual support or stability. However, all participants successfully maintained balance while walking and were able to perform the texting task with no significant change to accuracy or speed on either treadmill. From this paradigm it is evident that when university students are challenged to text while walking on either a tied-belt or split-belt treadmill, without any other distraction, their gait is minimally affected and they are able to maintain texting performance.

Abstract
BACKGROUND Colorectal cancer (CRC) is the second leading cause of cancer mortality in the US but is preventable with timely colonoscopy screening. Although CRC incidence and mortality have been decreasing and screening rates increasing, southeastern Coloradans in particular remain in great need of CRC screening. Media outreach campaigns have previously proven successful in this region, and local clinical partners expressed interest in text messaging and social media community outreach. METHODS The Colorado Cancer Screening Program partnered with the Colorado Cancer Coalition and two community health centers to develop theory-based text messages to encourage cancer screening behavior. Participants were recruited into this text message program through 4 weeks of radio advertisements, locally-posted flyers, and 12 weeks of social media messaging asking community members to text a key word or enter their phone number online to receive additional information about cancer screening. RESULTS Facebook advertisement proved to be the most successful in engaging community members in the outreach campaign with over 22,600 exposed to ads. Radio and print advertisements were less successful than previous campaigns suggested. Theory-based text messages were effective in maintaining interest in the topic of cancer screening. Ninety-six percent of text message participants remained enrolled through receipt of all CRC messages. CONCLUSIONS The EndCancer campaign provides evidence of strategies that can be used to reach hard-to-reach and hard-to-screen populations in need of CRC screening. Engagement was high with Facebook ads, and those who viewed ads clicked through to the sign-up page, an indication of intent to enroll. Given the promising results of engagement with Facebook ads among the target demographic, social media marketing may prove a successful avenue to enroll hard-to-reach populations into cancer screening educational initiatives.

Abstract
BACKGROUND In recent times, increasing safety concerns have been associated with the use of mobile phones by pedestrians. In particular, texting has been shown to significantly alter gait patterns. However, no specific investigations have been performed on people with Multiple Sclerosis (pwMS), who are already characterized by gait dysfunctions caused by the disease. OBJECTIVE To assess the existence of possible alterations in spatio-temporal parameters of gait in pwMS when simultaneously texting on a smartphone and walking. METHODS Fifty-four pwMS (mean age 40.5 ± 10.5) and 40 age-matched unaffected individuals were tested in two conditions: walking, and walking while texting on a smartphone. Spatio-temporal parameters of gait were assessed using a wearable accelerometer located on the lower back. RESULTS Texting induces reduction of gait speed, stride length and cadence in both groups, but such changes were smaller in magnitude in pwMS. An increase of stance and double support and reduction of swing phase were observed in pwMS only. CONCLUSIONS Texting alters gait patterns of pwMS differently from unaffected individuals, probably due to a different prioritization of the task, which appears to take into account the motor and sensory impairments associated with the disease by favoring the motor task.

Abstract
This study analysed and modelled the effects of conversation and texting (each with two difficulty levels) on driving performance of Indian drivers in terms of their mean speed and accident avoiding abilities; and further explored the relationship between speed reduction strategy of the drivers and their corresponding accident frequency. 100 drivers of three different age groups (young, mid-age and old-age) participated in the simulator study. Two sudden events of Indian context: unexpected crossing of pedestrians and joining of parked vehicles from road side, were simulated for estimating the accident probabilities. Generalized linear mixed models approach was used for developing linear regression models for mean speed and binary logistic regression models for accident probability. The results of the models showed that the drivers significantly compensated the increased workload by reducing their mean speed by 2.62m/s and 5.29m/s in the presence of conversation and texting tasks respectively. The logistic models for accident probabilities showed that the accident probabilities increased by 3 and 4 times respectively when the drivers were conversing or texting on a phone during driving. Further, the relationship between the speed reduction patterns and their corresponding accident frequencies showed that all the drivers compensated differently; but, among all the drivers, only few drivers, who compensated by reducing the speed by 30% or more, were able to fully offset the increased accident risk associated with the phone use.

Abstract
BACKGROUND Distracted pedestrian behavior is a significant public health concern, as research suggests distracted pedestrians have significantly higher risk of injury compared to fully attentive pedestrians. Despite this, efforts to reduce distracted pedestrian behavior are scant. OBJECTIVE Using a repeated measures experimental research design, we implemented a behavioral intervention to reduce distracted pedestrian behavior in the high-risk environment of an urban college campus and simultaneously monitored behavior on a control urban college campus not exposed to the intervention. We had two primary aims: reduce perceived vulnerability to injury among individual pedestrians and reduce distracted pedestrian behavior in the environment through a change in community-based norms. METHODS The hallmark of the behavioral intervention was a week-long opportunity for community members to experience personally the risks of distracted pedestrian behavior by attempting to cross a virtual pedestrian environment street while text-messaging. This was supplemented by traditional and social marketing and publicity through various campus partners. A sample of 219 individuals completed self-report surveys about perceived vulnerability to distracted pedestrian injury before experiencing the distracted virtual street-crossing and again after 2 weeks and 5 months. Observational assessment of distracted pedestrian behavior was conducted at a busy intersection on the campus as well as at a control campus not exposed to the intervention at baseline, post-intervention, 10 weeks, and 6 months. RESULTS The intervention achieved mixed results. Individuals exposed to texting within a simulated pedestrian environment reported changes in their intentions to cross streets while distracted and in perceived vulnerability to risk while crossing streets, but we did not witness evidence of changed community norms based on observed rates of distracted pedestrian behavior before and after the intervention compared to a control campus not exposed to the intervention. DISCUSSION The intervention created some change in self-reported intentions and thoughts but did not create significant behavior change on the campus exposed to it. Further efforts to develop interventions that will yield a reduction in distracted pedestrian behavior are needed.

Abstract
Mobile phone use while walking can cause dual-task interference and increases safety risks by increasing attentional and cognitive demands. While the interference effect on cognitive function has been examined extensively, how perception of the environment and walking dynamics are affected by mobile phone use while walking is not well understood. The amount of visual information loss and its consequent impact on dynamic walking stability was examined in this study. Young adults (mean, 20.3 years) volunteered and walked on a treadmill while texting and attending to visual tasks simultaneously. Performance of visual task, field of regard loss, and margin of stability under dual-task conditions were compared with those of single-task conditions (i.e., visual task only). The results revealed that the size of visual field and visual acuity demand were varied across the visual task conditions. Approximately half of the visual cues provided during texting while walking were not perceived as compared to the visual task only condition. The field of regard loss also increased with increased dual-task cost of mobile phone use. Dynamic walking stability, however, showed no significant differences between the conditions. Taken together, the results demonstrate that the loss of situational awareness is unavoidable and occurs simultaneously with decrements in concurrent task performance. The study indicates the importance of considering the nature of attentional resources for the studies in dual-task paradigm and may provide practical information to improve the safe use of mobile phones while walking.

Abstract
When young adults re-tell a story, they naturally produce more concise but sufficiently informative narratives. The repeated narratives of elderly adults, on the other hand, tend towards prolixity. In the present study, participants were explicitly instructed to re-tell a story in a more succinct (but informative format) to investigate whether they were able to produce informative narratives in a compressed format. 30 younger adults ([Formula: see text]) and 30 older adults ([Formula: see text]) constructed a verbal narrative from a series of cartoon frames depicting a story about a cowboy and his horse. Participants then re-told this narrative as a text message. The second narrative produced by the older adult sample did on average contain fewer words, but at the expense of informative content and discourse cohesion. The tendency of older adults to produce longer narratives with re-telling is not merely reflective of a strategic choice but rather reflects a genuine macrolinguistic deficit.

Abstract
This article explores the impact of social media on child development and family health. Why do we allow our children to use social media sites before their privacy policies allow? Why do we let them lie about their ages to use these sites? What is it about technology that lets us bend these rules in a way we would never do in the unplugged world? Gaining insight into the answers to these questions and what is positive and negative about social media and the digital world allows us to talk to families about this world, allay their concerns, and keep children of all age safe when using social media.

Abstract
OBJECTIVE To determine the impact of personality on distracted driving behaviors. METHOD Participants included 120 drivers (48 teens, 72 older adults) who completed the 45-item Big Five Personality questionnaire assessing self-reported personality factors and the Questionnaire Assessing Distracted Driving (QUADD) assessing the frequency of distracted driving behaviors. Associations for all five personality traits with each outcome (e.g., number of times texting on the phone, talking on the phone, and interacting with the phone while driving) were analyzed separately for teens and older adults using negative binomial or Poisson regressions that controlled for age, gender and education. RESULTS In teens, higher levels of openness and conscientiousness were predictive of greater reported texting frequency and interacting with a phone while driving, while lower levels of agreeableness was predictive of fewer reported instances of texting and interacting with a phone while driving. In older adults, greater extraversion was predictive of greater reported talking on and interacting with a phone while driving. Other personality factors were not significantly associated with distracted driving behaviors. CONCLUSIONS Personality traits may be important predictors of distracted driving behaviors, though specific traits associated with distracted driving may vary across age groups. The relationship between personality and distracted driving behaviors provides a unique opportunity to target drivers who are more likely to engage in distracted driving behavior, thereby increasing the effectiveness of educational campaigns and improving driving safety.

ACCIDENT; ANALYSIS AND PREVENTION 2016; 87:161-169.

Abstract
A systematic review and meta-analysis of naturalistic driving studies involving estimates of safety-critical event risk associated with handheld device use while driving is described. Fifty-seven studies identified from targeted databases, journals and websites were reviewed in depth, and six were ultimately included. These six studies, published between 2006 and 2014, encompass seven sets of naturalistic driver data and describe original research that utilized naturalistic methods to assess the effects of distracting behaviors. Four studies involved non-commercial drivers of light vehicles and two studies involved commercial drivers of trucks and buses. Odds ratios quantifying safety-critical event (SCE) risk associated with talking, dialing, locating or answering, and texting or browsing were extracted. Stratified meta-analysis of pooled odds ratios was used to estimate SCE risk by distraction type; meta-regression was used to test for sources of heterogeneity. The results indicate that tasks that require drivers to take their eyes off the road, such as dialing, locating a phone and texting, increase SCE risk to a greater extent than tasks that do not require eyes off the road such as talking. Although talking on a handheld device did not increase SCE risk, further research is required to determine whether it indirectly influences SCE risk (e.g., by encouraging other cell phone activities). In addition, a number of study biases and quality issues of naturalistic driving studies are discussed.
