Behavioral and social sciences theories and models: are they used in unintentional injury prevention research?

Behavioral and social sciences theories and models have the potential to enhance efforts to reduce unintentional injuries. The authors reviewed the published literature on behavioral and social science theory applications to unintentional injury problems to enumerate and categorize the ways different theories and models are used in injury prevention research. The authors conducted a systematic review to evaluate the published literature from 1980 to 2001 on behavioral and social science theory applications to unintentional injury prevention and control. Electronic database searches in PubMed and PsycINFO identified articles that combined behavioral and social sciences theories and models and injury causes. The authors identified some articles that examined behavioral and social science theories and models and unintentional injury topics, but found that several important theories have never been applied to unintentional injury prevention. Among the articles identified, the PRECEDE PROCEED Model was cited most frequently, followed by the Theory of Reasoned Action/Theory of Planned Behavior and Health Belief Model. When behavioral and social sciences theories and models were applied to unintentional injury topics, they were most frequently used to guide program design, implementation or develop evaluation measures; few examples of theory testing were found. Results suggest that the use of behavioral and social sciences theories and models in unintentional injury prevention research is only marginally represented in the mainstream, peer-reviewed literature. Both the fields of injury prevention and behavioral and social sciences could benefit from greater collaborative research to enhance behavioral approaches to injury control.

Using behavioral science to improve fire escape behaviors in response to a smoke alarm.

Although the likelihood of fire-related death in homes with smoke alarms is about one-half that in homes without alarms, alarm effectiveness is limited by behavior. Only 16% of residents of homes with alarms have developed and practiced plans for escape when the alarm sounds. We reviewed literature to identify behavioral constructs that influence smoke alarm use. We then convened experts in the behavioral aspects of smoke alarms who reviewed the constructs and determined that the appropriate areas for behavioral focus were formulating, practicing, and implementing escape plans should an alarm sound. They subsequently identified important behaviors to be addressed by burn-prevention programs and incorporated the constructs into a behavioral model for use in such programs. Finally, we organized the available literature to support this model and make programmatic recommendations. Many gaps remain in behavioral research to improve fire escape planning and practice. Future research must select the target behavior, apply behavioral theories, and distinguish between initiation and maintenance of behaviors associated with planning, practicing, and implementing home fire escape plans.

Association between state level drinking and driving countermeasures and self reported alcohol impaired driving.

OBJECTIVES: In 1999, alcohol related motor vehicle crashes in the United States claimed 15786 lives and injured more than 300000 persons. Drinking and driving behavior is shaped by individual and environmental level influences. In this study, the association between each state's driving under the influence of alcohol (DUI) countermeasures and self reported alcohol impaired driving was explored. METHODS: Mothers Against Drunk Driving's (MADD's) Rating the States 2000 survey, which graded states on their DUI countermeasures from 1996-99, was used as an index of each state's comprehensive DUI prevention activities. Information on alcohol impaired driving from residents of each state was obtained from the 1997 Behavioral Risk Factor Surveillance System (BRFSS) survey. The association between the MADD state grades and alcohol impaired driving was assessed using multiple logistic regression. RESULTS: Of the 64162 BRFSS respondents who reported drinking any alcohol during the past month, 2.1% of women and 5.8% of men reported at least one episode of alcohol impaired driving in the past month. Those living in states with a MADD grade of "D" were 60% more likely to report alcohol impaired driving than those from states with a MADD grade of "A" (odds ratio 1.6, 95% confidence interval 1.3 to 2.1). The association existed for men and women. CONCLUSION: These findings suggest that stronger state level DUI countermeasures are associated with lower rates of self reported alcohol impaired driving.

Methods for conducting systematic reviews of the evidence of effectiveness and economic efficiency of interventions to reduce injuries to motor vehicle occupants.

BACKGROUND: Motor vehicle occupant injury prevention is included in the Guide to Community Preventive Services because of the enormous health impact of these largely preventable injuries. This article describes the methods for conducting systematic literature reviews of interventions for three key injury prevention strategies: increasing child safety seat use, increasing safety belt use, and decreasing alcohol-impaired driving. METHODS: Systematic review methods follow those established for the Guide to Community Preventive Services and include: (1) recruiting a systematic review development team, (2) developing a conceptual approach for selecting interventions and for selecting outcomes that define the success of the interventions, (3) defining and conducting a search for evidence of effectiveness, (4) evaluating and summarizing the body of evidence of effectiveness, (5) evaluating other potential beneficial and harmful effects of the interventions, (6) evaluating economic efficiency, (7) identifying implementation barriers, (8) translating the strength of the evidence into recommendations, and (9) identifying and summarizing research gaps. RESULTS: The systematic review development team evaluated 13 interventions for the three strategic areas. More than 10,000 titles and abstracts were identified and screened; of these, 277 met the a priori systematic review inclusion criteria. Systematic review findings for each of the 13 interventions are provided in the accompanying articles in this supplement. CONCLUSION: The general methods established for conducting systematic reviews for the Guide to Community Preventive Services were successfully applied to interventions to reduce injuries to motor vehicle occupants.

Reviews of evidence regarding interventions to increase use of child safety seats.

BACKGROUND: In 1998, nearly 600 child occupants of motor vehicles aged younger than 4 years died in motor vehicle crashes. Yet approximately 29% of children aged 4 years and younger do not ride in appropriate child safety seat restraints, which, when correctly installed and used, reduce the need for hospitalization in this age group by 69% and the risk of death by approximately 70% for infants and by 47% to 54% for toddlers (aged 1 to 4 years). METHODS: The systematic review development team reviewed the scientific evidence of effectiveness for five interventions to increase child safety seat use. For each intervention, changes in the use of child safety seats or injury rates were the outcome measures evaluated to determine the success of the intervention. Database searching was concluded in March 1998. More than 3500 citations were screened; of these citations, 72 met the inclusion criteria for the reviews. RESULTS: The systematic review process identified strong evidence of effectiveness for child safety seat laws and distribution plus education programs. In addition, community-wide information plus enhanced enforcement campaigns and incentive plus education programs had sufficient evidence of effectiveness. Insufficient evidence was identified for education-only programs aimed at parents, young children, healthcare professionals, or law enforcement personnel. CONCLUSIONS: Evidence is available about the effectiveness of four of the five interventions we reviewed. This scientific evidence, along with the accompanying recommendations of the Task Force elsewhere in this supplement, can be a powerful tool for securing the resources and commitment required to implement these strategies.

Reviews of evidence regarding interventions to increase the use of safety belts.

BACKGROUND: The use of safety belts is the single most effective means of reducing fatal and nonfatal injuries in motor vehicle crashes. If all motor vehicle occupants consistently wore safety belts, an estimated 9553 deaths would have been prevented in 1999 alone. METHODS: The Guide to Community Preventive Services's methods for systematic reviews were used to evaluate the effectiveness of three interventions to increase safety belt use. Effectiveness was assessed on the basis of changes in safety belt use and number of crash-related injuries. RESULTS: Strong evidence was found for the effectiveness of safety belt laws in general and for the incremental effectiveness of primary safety belt laws relative to secondary laws. Strong evidence for the effectiveness of enhanced enforcement programs for safety belt laws was also found. Additional information is provided about the applicability, other effects, and barriers to implementation of these interventions. CONCLUSIONS: These reviews form the basis of the recommendations by the Task Force on Community Preventive Services presented elsewhere in this supplement. They can help decision makers identify and implement effective interventions that fit within an overall strategy to increase safety belt use.

Reviews of evidence regarding interventions to reduce alcohol-impaired driving.

BACKGROUND: Alcohol-related motor vehicle crashes are a major public health problem, resulting in 15,786 deaths and more than 300,000 injuries in 1999. This report presents the results of systematic reviews of the effectiveness and economic efficiency of selected population-based interventions to reduce alcohol-impaired driving. METHODS: The Guide to Community Preventive Services's methods for systematic reviews were used to evaluate the effectiveness of five interventions to decrease alcohol-impaired driving, using changes in alcohol-related crashes as the primary outcome measure. RESULTS: Strong evidence was found for the effectiveness of .08 blood alcohol concentration laws, minimum legal drinking age laws, and sobriety checkpoints. Sufficient evidence was found for the effectiveness of lower blood alcohol concentration laws for young and inexperienced drivers and of intervention training programs for servers of alcoholic beverages. Additional information is provided about the applicability, other effects, and barriers to implementation of these interventions. CONCLUSION: These reviews form the basis of the recommendations by the Task Force on Community Preventive Services presented elsewhere in this supplement. They can help decision makers identify and implement effective interventions that fit within an overall strategy to prevent impaired driving.

Driving cessation: what older former drivers tell us.

OBJECTIVES: To understand why older drivers living in a community setting stop driving. DESIGN: A cross-sectional study within a longitudinal cohort. SETTING: A geographically defined community in southern California. PARTICIPANTS: 1,950 respondents age 55 and older who reported ever being licensed drivers. MEASUREMENTS: A mailed survey instrument of self-reported driving habits linked to prior demographic, health, and medical information. RESULTS: Of the 1,950 eligible respondents, 141 had stopped driving within the previous 5 years. Among those who stopped, mean age was 85.5 years, 65.2% were female, and the majority reported they were in very good (43.4%) or good (34.0%) health. Nearly two-thirds reported driving less than 50 miles per week prior to stopping and 12.1% reported a motor vehicle crash during the previous 5 years. The most common reasons reported for stopping were medical (41.0%) and age-related (19.4%). In bivariate analyses, age and miles driven per week were each associated with cessation (P < or = .001). Medical conditions, crashes in the previous 5 years, and gender did not reach statistical significance at the P < or = .05 level. Logistic regression results found that the number of medical conditions was inversely associated with driving cessation. CONCLUSION: The relationship between medical conditions and driving is complex; while medical conditions were the most common reason given for driving cessation, those who stopped had fewer medical conditions than current drivers. This suggests that a broader measure of general health or functional ability may play a dominant role in decisions to stop driving.

Legislative and regulatory strategies to reduce childhood unintentional injuries.

Laws and regulations are among the most effective mechanisms for getting large segments of the population to adopt safety behaviors. These have been applied at both the state and federal levels for diverse injury issues. Certain legal actions are taken to prevent the occurrence of an otherwise injury-producing event, while other legal actions are designed to prevent injury once an event has occurred. At the federal level, effective laws and regulations have been directed at dangers posed by unsafe manufactured products or motor vehicle design. At the state level, effective safety laws and regulations have been directed at encouraging safety behaviors and regulating the use of motor vehicles or other forms of transportation. In this article, six legislative efforts are described to point out pros and cons of the legislative approach to promoting safety. Three such efforts are aimed at preventing injury-producing events from occurring: mandating child-resistant packaging for prescription drugs and other hazardous substances, regulating tap water temperature by presetting a safe hot-water heater temperature at the factory, and graduated licensing. Three other examples illustrate the value and complexities of laws designed to prevent injuries once an injury-producing event does occur: mandatory bicycle helmet use, sleep-wear standards, and child safety seat use. This article concludes with specific recommendations, which include assessing the value of laws and regulations, preventing the rescission of laws and regulations known to work, refining existing laws to eliminate gaps in coverage, developing regulations to adapt to changing technology, exploring new legal means to encourage safe behavior, and increasing funding for basic and applied research and community programs. Further reductions in childhood injury rates will require that leaders working in the field of injury prevention together provide the creativity to devise new safety devices and programs, incentives to persuade the public to adopt a "culture of safety" as a social norm, training and education to develop new leaders and workers, and the political will to challenge the status quo and engage the public interest.

Characteristics of child passenger deaths and injuries involving drinking drivers.

CONTEXT: Motor vehicle-related injury is the leading cause of death for children and young adults aged 1 to 24 years in the United States. Approximately 24% of child traffic deaths involve alcohol. OBJECTIVE: To examine characteristics of crashes involving child passenger deaths and injuries associated with drinking drivers to identify opportunities for prevention. DESIGN, SETTING, AND PARTICIPANTS: Descriptive epidemiological analysis of 1985-1996 datafrom the Fatality Analysis Reporting System on deaths among US child passengers (aged 0-14 years) and 1988-1996 data from the General Estimates System on nonfatal injuries. MAIN OUTCOME MEASURES: Child passenger death or injury by driver characteristics (eg, driver age, blood alcohol concentration, and driving history). RESULTS: In 1985-1996, there were 5555 child passenger deaths involving a drinking driver. Of these deaths, 3556 (64.0%) occurred while the child was riding with a drinking driver; 67.0% of these drinking drivers were old enough to be the parent or caregiver of the child. Of all drivers transporting a child who died, drinking drivers were more likely than nondrinking drivers to have had a previous license suspension (17.1% vs 7.1%) or conviction for driving while intoxicated (7.9% vs 1.2%). Child restraint use decreased as both the child's age and the blood alcohol concentration of the child's driver increased. In 1988-1996, an estimated 149,000 child passengers were nonfatally injured in crashes involving a drinking driver. Of these, 58,000 (38.9%) were riding with a drinking driver when injured in the crash. CONCLUSIONS: These data indicate that the majority of drinking driver-related child passenger deaths in the United States involve a child riding unrestrained in the same vehicle with a drinking driver. Typically, the drinking driver transporting the child is old enough to be the child's parent or caregiver.

Exercise-related injuries among women: strategies for prevention from civilian and military studies.

SCOPE OF THE PROBLEM: The numerous health benefits of physical activity have been well documented, resulting in public health support of regular physical activity and exercise. Although beneficial, exercise also has corresponding risks, including musculoskeletal injuries. The incidence and risk factors for exercise-related injury have been poorly assessed in women. Many civilian exercise activities (e.g., jogging, walking, and erobics) have corollaries in military physical training; injury incidence and risk factors associated with military physical training have been more thoroughly studied. ETIOLOGIC FACTORS: Injury risks increase as the amount of training increases (increased xposure). The same exercise parameters that can be modified to enhance physical fitness (i.e., frequency, duration, and intensity) also influence the risk for injury in a dose-response manner. Higher levels of current physical fitness (aerobic fitness) protect the participant against future injury. A history of previous injury is a risk factor for future injury. Smoking cigarettes has been associated with increased risk for exercise-related injury. Studies conducted in military populations suggest that the most important risk factor for injuries among persons engaged in vigorous weight-bearing aerobic physical activity might be low aerobic fitness rather than female sex. RECOMMENDATIONS FOR PREVENTION: Because of the limited scientific research regarding women engaging in exercise, general recommendations are provided. Women starting exercise programs should be realistic about their goals and start slowly at frequency, duration, and intensity levels commensurate with their current physical fitness condition. Women should be informed about the early indicators of potential injury. Women who have sustained an injury should take precautions to prevent reinjury (e.g., ensuring appropriate recovery and rehabilitation). RESEARCH AGENDA: In general, a combination of factors affects the risk for exercise-related injury in women. How these factors act singly and in combination to influence injury risk is not well understood. Additional research regarding exercise-related injury in women is needed to answer many of the remaining epidemiologic questions and to help develop exercise programs that improve health while reducing the risk for injury. CONCLUSION: Exercise is an important component in improving and maintaining health; however, injury is also an accompanying risk. A review of key military and civilian research studies regarding exercise-related injuries provides some clues to reducing these injuries in women. Greater adherence to exercise guidelines can help decrease these risks.

Prevalence of alcohol-impaired driving. Results from a national self-reported survey of health behaviors.

OBJECTIVE: To estimate how frequently adults in the United States drive while impaired by alcohol. DESIGN: Telephone survey. SETTING: The 49 states (and the District of Columbia) that participated in the Behavioral Risk Factor Surveillance System (BRFSS) in 1993. PARTICIPANTS: A total of 102,263 noninstitutionalized adults aged 18 years or older. MAIN OUTCOME MEASURES: The percentage of respondents who reported alcohol-impaired driving; number of episodes of alcohol-impaired driving per 1000 adult population; and total number of episodes of alcohol-impaired driving-each by age, sex, race, level of education, and state. RESULTS: Overall, 2.5% of adults reported an estimated 123 million episodes of alcohol-impaired driving in 1993. This corresponds to 655 episodes of alcohol-impaired driving for each 1000 adults (range among states per 1000 adults, 165-1550). Alcohol-impaired driving was most frequent among men aged 21 to 34 years (1739 episodes per 1000 adults) and was nearly as frequent among men aged 18 to 20 years (1623 episodes per 1000 adults), despite legislation in all states that prohibited the sale of alcohol to persons younger than age 21 years in 1993. CONCLUSIONS: Alcohol-impaired driving is common even among underage persons. Strict enforcement of laws that discourage alcohol-impaired driving is needed along with community and patient education to reduce the prevalence of alcohol-impaired driving and prevent injuries and deaths from alcohol-related motor vehicle crashes. Data from the BRFSS, an ongoing source of national and state-specific data on the number of episodes of alcohol-impaired driving, are potentially useful for monitoring trends and evaluating the effect of future efforts to reduce alcohol-impaired driving.

Which prevention strategies for child pedestrian injuries? A review of the literature.

In 1992, motor vehicle-related injury was the leading cause of injury-specific death in the United States for children aged zero to fourteen years. In the five to nine years age group, childhood pedestrian injury was exceeded only by motor vehicle occupant injuries as the leading cause of death. The prevention of these injuries is a multifactorial problem involving individual characteristics of the child, environmental design, and the mutual dependence between the child and his or her environment. This article considers the plethora of descriptive and analytical research and proposes suitable strategies to reduce the rate of child pedestrian injury.

Potential consumer participation in a boycott of tobacco-company-owned nontobacco products.

A random telephone survey was conducted to measure the public's willingness to participate in a boycott of popular consumer products manufactured by corporations owned by tobacco companies. Results suggest a strong interest in such a boycott. Previous boycott experiences, attitudes, and smoking statuses significantly predicted subjects' willingness to participate. Age was inversely related to willingness to participate, while sex, income, ethnicity, and education were not related to this variable.

Motor vehicle trauma and safety belt use in the context of public health priorities.

Public health priorities arise from the convergence of a disease threat, public awareness of the threat, demand for proper protection from the threat, and a body of scientific literature to support the effectiveness of prevention/protection measures. With the success in combating infectious and some chronic diseases, public health is beginning to turn next to the challenge of a "new" pandemic, injury, especially to the prevention of motor vehicle trauma. Programs that promote the use of safety belts, child restraints, and automatic protection in the context of public health priorities offer the greatest hope for reducing the magnitude of the motor vehicle trauma problem.
