Evaluating traffic informers: Testing the behavioral and social-cognitive effects of an adolescent bicycle safety education program

AbstractIn The Netherlands, 12–24 years old are over-represented in the total number of traffic fatalities and injuries. In this study, the traffic informer program – designed to promote safe traffic behavior in the pre-driver population – was experimentally evaluated, with a specific focus on bicycle use. Students were subjected to graphic videos of traffic accidents and listened to a first-person narrative provided by a traffic accident victim. The influence of the program on concepts derived from the theory of planned behavior and protection motivation theory (attitudes, norms, self-efficacy, risk-perception, intention and behavior) was assessed. Students from various schools (N=1593;M age=15 years, SD=.84) participated in a quasi-experimental study, either in an experimental or a control group, completing self-report questionnaires one week prior to the program implementation and approximately one month after the program implementation. Mixed regression analyses showed significant positive and negative time×intervention interaction effects on attitude toward traffic violations, relative attitude toward traffic safety, and risk comparison, but not on intention and behavior. More research is needed to find effective behavioral change techniques (other than increasing risk awareness) for promoting safe traffic behavior in adolescents. Research is also needed to address how these can be translated into effective interventions and educational programs

Measuring working memory load effects on electrophysiological markers of attention orienting during a simulated drive

Intersection accidents result in a significant proportion of road fatalities, and attention allocation likely plays a role. Attention allocation may depend on (limited) working memory (WM) capacity. Driving is often combined with tasks increasing WM load, consequently impairing attention orienting. This study (n = 22) investigated WM load effects on event-related potentials (ERPs) related to attention orienting. A simulated driving environment allowed continuous lane-keeping measurement. Participants were asked to orient attention covertly towards the side indicated by an arrow, and to respond only to moving cars appearing on the attended side by pressing a button. WM load was manipulated using a concurrent memory task. ERPs showed typical attentional modulation (cue: contralateral negativity, LDAP; car: N1, P1, SN and P3) under low and high load conditions. With increased WM load, lane-keeping performance improved, while dual task performance degraded (memory task: increased error rate; orienting task: increased false alarms, smaller P3). Practitioner Summary: Intersection driver-support systems aim to improve traffic safety and flow. However, in-vehicle systems induce WM load, increasing the tendency to yield. Traffic flow reduces if drivers stop at inappropriate times, reducing the effectiveness of systems. Consequently, driver-support systems could include WM load measurement during driving in the development phase

Understanding the role played by parents, culture and the school curriculum in socializing young women on sexual health issues in rural South African communities

BACKGROUND: the decline in South Africa’s HIV infection rates especially among young women is encouraging. However, studies show that the 15–24-year-old cohort remains vulnerable. As they still report early sexual debut, being involved in sexual partnerships with older men as well as having unprotected sex. These risky sexual behaviors may be linked to factors such as the parent–child sexual health communication and the timing of the first talk. The quality of sexual health information received in school may also be important for enhancing healthier sexual behaviors. AIMS AND OBJECTIVES: to investigate the what, when and how sexual health communication occurs in rural South African families and to determine whether such communication patterns have changed over time. We also wanted to get an in-depth understanding of the roles played by culture, sexual health education and peers in the socialization of young women on sexual matters. METHODS: a purposive sample of (n = 55) women who were 18–35 years old was selected and interviewed in focus group discussions (FGDs). Results: the FGD findings show that parent–child communication on sexual matters in rural communities is limited to messages that warn against pregnancy. It is also laden with cultural idioms that are not well explained. The school sexual health curriculum also fails to adequately equip adolescents to make informed decisions regarding sexual matters. All this seems to leave room for reception of misguided information from peers. CONCLUSIONS: findings highlight a need for designing interventions that can create awareness for parents on the current developmental needs and sexual behavior of adolescents. For adolescents programs would need to focus on providing skills on personal responsibility, and how to change behavior to enhance sexual health.DHETDHE

Core Processes:How to Use Evidence, Theories, and Research in Planning Behavior Change Interventions

Psychology is not only a basic behavioral science but also an applied discipline that is used to solve societal problems. In a problem-driven context, the search for existing literature, the correct application of appropriate theories, and the collection of additional research data are basic tools essential for the systematic development of any theory- and evidence-based behavior change intervention. The processes of brainstorming, literature review, theory selection and application, and data collection are "Core Processes" that can be used in different phases/steps of intervention planning-from needs assessment to intervention design to program implementation and evaluation-and within different planning frameworks. In this paper, we illustrate how the use of these "Core Processes" provides expert, empirical and theoretical guidance to planners from problem definition to problem solution. Specific emphasis is put on finding theories that are potentially useful in providing answers to planning questions using a combination of approaches to access and select theories (i.e., the topic, concept, and general theories approaches). Furthermore, emphasis is put on the logic of answering planning questions in a specific order by first brainstorming before consulting the literature, then applying theories, and finally collecting additional data.</p

The Future Positive micro-intervention protocol:A program aiming to increase a healthy life-style among employees with a low socio-economic position

This paper describes the development of a Dutch micro-intervention, Future Positive, that aims to increase health behaviors among employees with a low socio-economic position (SEP), with the ultimate aim to decrease socio-economic health inequalities. Intervention Mapping (IM) was used to adapt previously developed psychological capital interventions into a micro-intervention suitable to be delivered in the work context for employees with a low socio-economic position. The first 4 steps of IM including the results of pre-testing the developed intervention program are described. Step 1 consists of the needs assessment, and investigated (a) the individual determinants of health behavior and health inequalities, and (b) the needs of employees with a low SEP and their employers regarding the implementation of the intervention at the worksite. Matrices-of-change were produced in Step 2, and relevant methods and applications were selected in step 3. Step 4 involved the intervention development, resulting in a brief micro-intervention that will be delivered in small groups, guided by trained facilitators using motivational interviewing techniques. Program materials include informative video-clips and active and cooperative learning exercises. The intervention was pre-tested among three groups of employees. The IM process, as well as the pre-testing, revealed that emphasizing autonomy and using easy to understand and mostly visual materials offered in chunks is essential for a well-tailored intervention that is suitable for people with low SEP. Also, participation should be facilitated by employers: It should be free of costs, offered during working hours, and take place at the job site. Results showed that the Future Positive micro-intervention is substantiated by theory, applicable in a work setting (high reach), and tailored to the needs of employees with a low SEP. We therefore fill the gap in this existing range of interventions aimed to improve life-style behaviors and contribute to theory-based interventions aimed to decrease the SEP-Health gradient

Developmental Assets in South African Adolescents Exposed to Violence: a Qualitative Study on Resilience

Violence exposure is associated with psychological and behavioural maladjustment in adolescents. Yet, not all adolescents exposed to violence experience negative symptoms. Resilience is an outcome that is in part determined by multiple protective factors, or developmental assets, that protect adolescents from the negative influence of encountered stressors and allow them to attain positive developmental outcomes. A qualitative study was conducted to acquire an in-depth understanding of the developmental assets across different layers in the ecological system that promote positive psychological and behavioural functioning in South African adolescents exposed to violence. Semi-structured individual interviews were conducted with a multi-ethnic group (black, white, and people of mixed heritage) of South African adolescents (boy: n = 17; girl: n = 13; age: 14-19 years) from seven schools in Cape Town. Adolescents reported both internal and external assets that helped them adaptively cope with violence exposure. The internal assets entailed individual characteristics and skills, including commitment to learning, positive values, positive identity, social competencies, and emotional insight. The external assets were boundaries and expectations, social support from adolescents' peers, family, school, and community, and adolescents' constructive use of time. The findings of the study may inform strengths-based interventions to enhance emotional and behavioural skills in adolescents at risk for violence exposure. Moreover, involving key stakeholders in the interventions from major developmental domains can be particularly helpful to optimise the social support that are needed for adolescents to be resilient
