Risk compensation theory and bicycle helmets – Results from an experiment of cycling speed and short-term effects of habituation

It has been suggested that the safety benefits of bicycle helmets are limited by risk compensation. The current study contributes to explaining whether the potential safety effects of bicycle helmets are reduced by cyclists’ tendency to cycle faster when wearing them (as a result of risk compensation), and if this potential reduction can be associated with a change in perceived risk. A previous study (Fyhri & Phillips, 2013) showed that non-routine helmet users did not increase their speed immediately after being given a helmet to wear, while routine helmet users cycled more slowly. The current study tests whether the previously found reduction in speed in response to helmet removal – as an indirect indicator of risk compensation – could be established in non-routine helmet users, after a period of habituation while cycling with a helmet.We did this by conducting a randomized crossover trial, in which we used GPS-derived speed calculations and self-reported risk perception. To test the effect of habituation, we used a design where each participant took part in two rounds with a break between and each round having two trips. We collected the data in June 2015. Non-routine helmet users (N = 31) were recruited in the field (along cycle routes in Oslo), and through a sample drawn from the Falck National register of bicycle owners. In the first phase of the study, all participants were asked to complete a test route (2.4 km downhill) with and without a helmet. In the second phase of the experiment, conducted after 1.5–2 h, the same participants again completed the test route with and without a helmet. In the time between the first and second phases of the experiment, all participants were given helmets, and told to use them on a predefined bicycle route.Habituation to the helmet between the first and second phases of the experiment did not produce any decrease (with helmet removal) in speed, on top of the habituation that occurred while cycling down the hill (the order effect). Mean speed difference for cycling with/without a helmet before the break was −0.76 km/h, after the break this difference was 0.32 km/h; 95% CIs [−0.5, 2.9] and [−0.9, 1.5]. We argue that risk compensation is an unlikely effect of using a bicycle helmet, and probably cannot explain any adverse effects related to helmet legislation.     

Determinants of standard motorcycle safety helmet usage among child pillion riders

The World Health Organization stressed that compliance with the use of safety helmet could significantly reduce the risk of injury by 72% and the probability of death by 39%. In Malaysia, the enforcement of the safety helmet legislation significantly reduced 30% of motorcycle crash fatalities in Malaysia. The aim of this study is to explore the use of motorcycle helmets and the determinants of standard helmet usage among child pillion riders. A cross-sectional survey of 200 adult riders accompanied by the child pillion riders aged 6–12 years old from Klang, Selangor, was conducted. The proper use of the helmet among the respondents and the child pillion riders was observed and recorded. A questionnaire was used to assess socio-demographic background and awareness of the use of child safety helmets. The data was analyzed using SPSS version 23. Only 3% of child pillion riders use standard child safety helmets, while 37% wear standard adult motorcycle helmets. Adult riders who were married, female, always wear helmets, have a higher household income and travel a long distance, are more likely to use a standard motorcycle helmet for their child pillion riders. Knowledge on Standard Certification (SIRIM) label and its importance, awareness of the campaign on child safety helmets, police enforcement, understanding the safety of toy/game helmet use have been identified as additional determinants of standard helmet use among child pillion riders. This study recommends prospective studies with continuous road safety educations programs that integrate behavioural change approaches to enhance the use of standard motorcycle helmets among the child pillion riders in Malaysia.     

Rewarding safety belt usage at an industrial setting: Tests of treatment generality and response maintenance

An incentive program to motivate seat belt use was implemented at a large munitions plant. Seat belt usage was assessed daily at an entrance/exit gate of the industrial complex when employees arrived for work in the morning and departed in the afternoon. During treatment incentive fliers, which prompted seat belt usage and gave belt wearers opportunities to win prizes, were distributed only in the afternoon. Seat belt wearing increased from baseline means of 20.4% and 17.3% during the morning and afternoon, respectively, to averages of 55.5% during afternoon departures and 31.1% during morning arrivals. During follow-up, mean belt use dropped almost to baseline levels. Categorizing vehicles according to driver sex and license plate number enabled a study of belt wearing practices of individuals, and revealed that the incentive program influenced some drivers to wear their seat belts during morning arrival when incentives were not distributed (i.e., treatment generalization) and during a follow-up period after the incentives were withdrawn (i.e., response maintenance).     

A model of factor analysis: Reasons for using a helmet in a sample of non-competitive Italian cyclists

IntroductionThe increased bicycle use for transport as an alternative to motorized vehicles has by now become a common occurrence in all Italian cities. Even though the benefits of using a helmet to protect against trauma in bicycle accidents have been demonstrated, its use is still limited. The objective of this study is to analyse those motivations for helmet wearing that can influence their adoption.MethodsData was gathered through an online questionnaire in collaboration with the Federazione Italiana Amici della Bicicletta (Italian Federation of Friends of the Bicycle), a recreational cyclists association.Motivations to use a helmet were investigated using a factorial analysis model. Factors were analysed through a points allocation system and compared according to gender, area of residence and whether the cyclist was a helmet-enthusiast.ResultsThe sample was made up of 1781 individuals, with a declining participation rate from North to South; 63% of respondents were men.Three factors were identified from the sample: helmet use as a safety benefit; helmets being perceived as a hindrance; and helmet used out of habit as well as to follow the virtuous example of friends and/or acquaintances during cycling outings. The major kinds of evidence are: regarding gender, differences in the perception of a helmet as a hindrance (p < 0.001) and its use out of habit (p < 0.001); as for area of residence, differences in the perception of a helmet as a hindrance (p = 0.01) and its use out of habit (p < 0.01); as regards being a helmet-enthusiast, differences were found for all the factors (p < 0.01).ConclusionsThese results contribute to understanding the scenario that affects motivational beliefs through facilitating or deterring cyclists from using a helmet during recreational cycling. The evidence suggests how to argue the helmet use discussion among Italians. In such a homogeneous population of respondents in terms of passion for cycling, opinions on helmet use were dissimilar from the point of view of both its perception and the subsequent motivation for using it.Exploring perceptions and motivations on helmet use is a key element in understanding cyclists’ behaviour in order to characterize different users. A combination of friends/peer influence, reduction in the perception of helmets as a hindrance, and reinforcing of safety could represent the starting point for planning interventions.     

An observational study of restraint and helmet wearing behaviour in Malaysia

Unrestrained and unhelmeted occupants are at increased risk of severe injury or death in the event of a crash, and there is evidence that children, particularly in low and middle income countries, have low restraint and helmet wearing rates.Roadside observations of occupants of passing vehicles (7247 cars, vans and taxis and 2897 motorcycles) in nearside lanes were made at seven selected road sites located around the Klang Valley (greater Kuala Lumpur) area representing a variety of demographic locations.The findings revealed an overall low rate of seat-belt wearing in vehicles (front seat drivers: 44.6%; front seat adult passengers: 33.8%; front seat child passengers: 11.8%; rear seat adult passengers: 5.2%; and, rear seat child passengers: 5.8%). For motorcyclists, the majority of adult riders and pillions wore helmets (93.4% and 85.8%, respectively), however a substantial proportion (40%) did not fasten their helmet properly. Of children observed on motorcycles, only 30.5% wore helmets.This study shows low seat-belt and helmet wearing rates, despite enactment of legislation that requires all vehicle passengers to be restrained and for all motorcyclists to wear helmets. This was particularly evident for children (front and rear seating positions) and rear seat adult passengers. It is suggested there is a general lack of awareness of safety and the benefits of restraint/helmet use, and lack of adequate and appropriate enforcement. The implications of the findings are discussed in terms of promoting restraint/helmets use, enforcement of legislation and implementation of technologies to increase appropriate restraint/helmet use.     

Bicycle helmets – A case of risk compensation?

Several studies have shown that bicycle helmets have the potential of reducing injuries from accidents. Yet, no studies have found good evidence of an injury reducing effect in countries that have introduced bicycle helmet legislation. Two of the most promising explanations for why helmet laws do not work as intended are risk compensation and shifts in the cycle population as a response to the law.The present article investigates whether the lack of effect of helmet wearing laws is due to risk compensation mechanisms or population shifts (i.e. discouraging cyclists with the lowest accident risk, and thereby increasing the overall average risk per cyclist). A random sample of 1504 bicycle owners in Norway responded to a questionnaire on among other things helmet use, bicycle equipment use, accident involvement, cycling behaviour and risk perception. Data were analysed by using structural equation model (SEM). The results show that the cyclist population in Norway can be divided into two sub-populations: one speed-happy group that cycle fast and have lots of cycle equipment including helmets, and one traditional kind of cyclist without much equipment, cycling slowly. With all the limitations that have to be placed on a cross sectional study such as this, the results indicate that at least part of the reason why helmet laws do not appear to be beneficial is that they disproportionately discourage the safest cyclists.     

Conflict resolution and peer mediation in middle schools: extending the process and outcome knowledge base

Many professional educators are implementing school-based prevention focused on conflict resolution (CR) and peer mediation (PM). The authors conducted research on CR-PM in 3 middle schools. Specifically, they surveyed teachers and students, tracked disciplinary incidents across school years, collected mediation data, and compared mediators with a matched sample to determine attitudinal change as a result of PM training and experience. The authors also surveyed peer mediators and disputants about program satisfaction, as well as peer mediators and their parents about the generalization of PM skills. The authors conclude with implications for developing future CR programs, including a focus on mediation-process evaluation as well as schoolwide outcome measures and the use of peer mediation training as an intervention for students at risk.

Evaluating Check-In Check-Out With Peer Tutors for Children With Attention Maintained Problem Behaviors

School Wide Positive Behavior Support provides schools with three tiers of support to address both academic and behavior challenges. The purpose of this study was to evaluate the use of peer tutors with three elementary students when applied to a Tier 2 intervention known as Check-In Check-Out (CICO). Peer tutors performed the morning check-in with the tutees by setting the expectations for the day and giving the tutees their Daily Progress Report (DPR) form. Throughout the day, the tutees took the DPR form to each class where they received a score from the teacher. At the end of the class period, the peer tutors provided the tutees with feedback on the scores received on the DPR form. Once the school day finished, the peer tutees checked-out with the tutors and received a reward if they met their percentage goal. The results of this study showed that CICO implemented by peers improved classroom behavior for all three participants.     

Addressing the Challenges Faced by Early Adolescents: A Mixed-Method Evaluation of the Benefits of Peer Support

In this article, we describe a mixed-methods study used to examine the effectiveness of a widely-used peer support program designed to facilitate the transition to adolescence and high school by enhancing self-concept and other desirable outcomes. For the quantitative component, a longitudinal design was employed (930 Grade 7 students, 3 schools, 2 years), with control group and baseline (i.e., pre-program) data against which to compare the effects. Using a multilevel approach, the results provide evidence to suggest that the program was largely successful in achieving its aims of enhancing students’ school self-concept, school citizenship, sense of self and possibility, connectedness, and resourcefulness. A sub-sample of students from the experimental group participated in the qualitative component, which included open-ended survey results (n = 408 Grade 7 students, n = 75 peer support leaders) and focus groups (n = 119 Grade 7 students, n = 44 peer support leaders) to identify students’ personal perspectives of the program. The qualitative results confirmed the quantitative findings that the program has important benefits for Grade 7 students and provided rich and valuable insights into students’ views of the intervention. The findings of this research have important implications and suggest that the provision of peer support has the potential to a make significant contribution to schools’ efforts to orchestrate positive outcomes for adolescents.     

Modification of school attendance for an elementary population

The staff and students of a school composed of Grades 1 through 3 participated in a program to increase school attendance. Children earned the opportunity to attend part or all of a monthly party by their attendance. Immediate feedback occurred each morning by placing stars on a classroom chart for each child present. The school's attendance during the program was compared both with attendance during preceding years and with attendance at other schools. The experimental school's attendance improved dramatically to become the best of all elementary schools in the system.     

A Multilevel Analysis of the Effects of Parents, Teachers and Schools on Student Values

Do schools influence the values of the students who attend them? This study examines the influence of parents, peer groups, teachers and the schools on student values as assessed by the Schwartz Value Survey. A sample of students at Grade 12 was chosen from 11 South Australian secondary schools of a wide variety of types, and the students, their parents and their teachers completed the Value Survey, and students also provided sociodemographic information. The data were analysed using the HLM multilevel analysis program with respect to the four higher order value components, namely self-transcendence, self-enhancement, conservation and openness to change in order to identify student level and school level effects on the values held by the students. Results showed that sex of student, language background, the Christian involvement of the student, parental social position and the values held by parents and peer groups had much greater effects upon the students' values than the schools and their teachers. Further research involving a larger number of schools in a wider variety of settings is suggested to build on this exploratory study.     

Expectations of efficacy,social influence and age as predictors of helmet-use in a sample of Spanish adolescents

Despite the proven effectiveness of helmets in avoiding or reducing the severity of brain injuries and the law requiring their compulsory use, both by drivers and passengers of motorcycles, approximately 20% of Spanish adolescent motorcycle users do not wear them. This study analysed the pattern of motorcycle and helmet-use in a sample of Spanish adolescents (age range 14–17; n = 874) and the relationship this safety measure has with belief in its effectiveness and its use by friends and relatives. Overall more males than females ride motorcycles and this difference increased with age. Motorcycle drivers and passengers who always wear helmets consider them to be more effective than those who do not use a helmet all of the time. The best predictors of helmet-use among motorcycle drivers were their beliefs regarding the helmet-use of their friends and relatives. In the case of passengers, knowing that their friends always wear them and age were the best predictors of helmet-use. Programmes and campaigns promoting helmet-use must take into account the modelling effect of close referents or other role models in order to increase their effectiveness.     

A six-district study of educational change: direct and mediated effects of the child development project

A comprehensive elementary school program, the Child Development Project, was conducted in two schools in each of six school districts over a three-year period. Two additional schools in each district served as a comparison group. The program attempts to create a 'caring community of learners' in school and classroom through classroom, schoolwide, and parent involvement components. The classroom component includes student collaboration, a literature-based approach to reading, and a student-centered approach to classroom management. Classroom observation, student questionnaire, teacher questionnaire, and test data were collected in a baseline year and in each of the three years of program implementation. Results showed positive student results in the five program schools that made significant progress in implementation. Schools that progressed in implementation showed gains – relative to their comparison schools – in students' personal, social, and ethical attitudes, values, and motives. Significant effects on academic achievement were found only in two schools with a performance-based assessment and a highly consistent local reform mandate. Modeling analyses indicated that student sense of community was an important mediating variable for almost all dependent variables – indicating that the program produced positive effects to the degree that it was successful in establishing a caring community in the school.     

The impact of a peer counselling scheme to address bullying in an all‐girl London secondary school: A short‐term longitudinal study

Background A variety of peer support schemes are now widely used in schools, notably to reduce bullying. However, there has been little systematic investigation of the impact and effectiveness of these approaches. Aims To assess the impact of a peer counselling scheme on peer counsellors and the school community. Sample The research was conducted in a North London all‐girls state secondary school. Data were collected from all lower school classes (years 7, 8, and 9) and some staff members, in addition to year 10 peer counsellors and an age equivalent comparison group. Method A detailed 1‐year longitudinal study combined qualitative and quantitative methods of assessment. Results Peer counsellors benefited from their involvement through an acquisition of transferable communication and interpersonal skills, and, compared to age‐matched control pupils, had increased social self‐esteem. There were no reductions in self‐reported bullying and victimization, but in general pupils believed that there was less bullying in school and that the school was doing more about bullying, with year 7 students showing the most positive changes. Conclusions Peer‐counselling schemes can improve self‐esteem of peer supporters, and also impact positively on perceptions of bullying in the school; but impact on actual experiences of bullying is less clear, and there may be problems with the acceptance and use of such programmes by older students.     

Multiple peer victimization among elementary school students: relations with social-emotional problems

Research has indicated that children exposed to multiple risks often report worse mental health and academic performance than those experiencing only one risk. The present research examines whether exposure to more than one form of peer victimization (multiple peer victimization) at school is related to reports of negative outcomes. Eighty-six fourth and fifth grade students self-reported exposure to peer victimization and social-emotional problems. MANCOVAs indicated that children who experienced multiple peer victimization reported higher depressive symptoms, lower self-esteem, and self-blame attributions for their own victimization, than those who experienced victimization in only one form or none at all. Peer victimization to/from school was also investigated. While peer victimization was found to occur on the way to/from school, adding this to victimization at school did not show the same cumulative effects. Implications for schools are discussed.     

ROLE REVERSALS: AN ANALYSIS OF THERAPEUTIC EFFECTS ACHIEVED WITH DISRUPTIVE BOYS DURING THEIR APPOINTMENTS AS PEER MONITORS

Three 7-year-old boys with histories of negative interactions were appointed to monitor individual classmates during daily noon recess. As monitors, the boys awarded points to their classmates for playing appropriately and, on rare occasions, withdrew a point for negative interactions. The three boys immediately decreased their own rates of negative interactions during the sessions in which they were appointed as monitors. Two of the boys concomitantly increased their rates of positive interactions. Their reductions in negative interactions were not maintained during reversals and did not clearly generalize to the morning or afternoon recess periods. Subsequent appointment of the boys as peer monitors during the morning recess produced similar improvements in their behavior. Results suggest that appointment to the role of peer monitor may itself function as an intervention.     

A motivational environment for behaviorally deviant junior high school students

A contingency management program was established in a junior high school to better manage and educate students having histories of severe misconduct. School administrators selected 46 eighth-graders having multiple suspensions for misbehavior. Students (N=32) in two of the schools remained in traditional programs, serving as controls, whereas students (N=14) in the third school participated in a token reinforcement program. Reinforcers provided in the afternoon were contingent upon achievement and discipline during morning academic periods. Home-based reinforcers were established to support school behavior. Compared with the control group, significant reductions in negative school behavior as well as greater increases in academic achievement were obtained for the treatment group, thus supporting the efficacy of contingency management for adolescent school misbehavior.Valuable assistance in developing the reinforcement program and curriculum materials was provided by William Brown, principal of the Anne Arundel County Learning Center. Thanks are also due: Dottie Dpwling and Joe Gentile, the teachers in the program; John Jedlicka, principal of Stemmers Run Junior High; and Donnie Williams, research assistant.     

儿童父母拒绝与同伴拒绝的关系:问题行为的中介作用和家庭环境纷杂度的调节作用

为探讨儿童父母拒绝、问题行为、家庭环境纷杂度和同伴拒绝的关系,该研究构建了一个有调节的中介模型。采用自我报告、母亲报告和同伴提名的方式对济南市三所小学4年级至6年级共307名被试进行测查,结果表明：（1）父母拒绝对儿童的同伴拒绝和外化问题行为均有显著的正向预测作用;（2）儿童的外化问题行为在父母拒绝与同伴拒绝之间起部分中介作用;（3）家庭环境纷杂度调节了父母拒绝通过儿童的外化问题行为影响同伴拒绝的中介过程的前半路径,即低家庭环境纷杂度可以作为一种保护因素,降低遭受父母拒绝的儿童出现外化问题行为的风险。
