Policy development is 1 of the 3 core functions of public health as well as a key component of the National Public Health Performance Standards that are used for accreditation of public health departments.1 Policy-making skills are included in the Core Competencies for Public Health and are a required part of the curriculum for public health schools and programs to receive Council on Education for Public Health accreditation.2

The role of policy development in public health has gained importance with the emergence of the “Health in All Policies” (HiAP) perspective, which is an approach to systematically assess public policies across sectors that takes into account the health and health systems implications of decisions, seeks synergies, and avoids harmful health impacts to improve health.3,4 It is a focus on the consequences of broad-ranging public policies on health determinants and aims to improve the accountability of policy makers for health impacts at all levels of policy making.3,4

For the injury prevention field, policies and resulting laws have led to great successes. This is critical since in the first half of life, more Americans die from violence and injuries than from any other cause, including cancer, human immunodeficiency virus, or the flu ( However, deaths are just the tip of the iceberg as every year millions of people are injured and live but can be faced with lifelong mental, physical, and financial issues ( Examples of important laws that have saved many lives include mandatory seat belt laws, pool fencing laws, drinking and driving laws, smoke detector laws, and more.5 Policies are an important way to achieve injury prevention intervention goals and have been said to be particularly effective since they are designed to affect large numbers of individuals or institutions at once.6 In fact, it has been shown that legislation and regulation, especially in reference to unintentional injuries, are the most effective interventions for injury prevention.5 Injury prevention also greatly benefits from HiAP, since the preponderance of injury-related policies needs to be addressed through sectors outside the immediate control of public health officials, placing a greater burden on public health professionals to have skills in influencing policy development.

Child injury prevention specialists have strongly supported the need to use HiAP to develop, mobilize, and implement child injury prevention action plans and ensure that child injury prevention is a part of any local HiAP initiative.7 This approach uses a cross-sector coalition of decision makers to develop action plans, allowing each sector to look at its decision-making process to incorporate prevention considerations in policy, and have sector representatives champion adoption of the plan within respective agencies, sectors, and businesses. For example, the sectors of transportation and land use are important in the development of injury prevention interventions for children related to motor vehicle injury prevention and keeping streets safe. These sectors should be partners in prevention efforts.7

The experience and knowledge of public health professionals is critical to effective advocacy for health change in reducing injury morbidity and mortality.8 For example, public health injury prevention staff can be strong advocates for effective health policy change, resulting in lower injury-related morbidity and mortality.9,10 Guidance exists that allows such advocacy within prohibitions against lobbying with Federal or other funding. For example, state and local public health injury prevention staff can engage in efforts such as participating in town meetings, conducting public forums, or helping to develop an issue brief on a particular injury topic.8 Also, the Centers for Disease Control and Prevention has addressed the issue of allowable advocacy (see

Injury Prevention Planning and Policy Tools

Injury prevention workers have access to several planning and policy tools to help them develop programs and initiatives and show effectiveness of policy-related interventions. For example, the Haddon Matrix has long been used as a planning tool for the development of injury prevention interventions and its components include the host, agent of injury, and the physical and social environment that interact over time to cause injury (pre-event, event, and postevent).11 This Matrix is supported by the original 3 Es of injury prevention known as education, engineering, and enforcement, with the latter being greatly related to laws and policies.9 The Spectrum of Prevention model is also an important tool in injury prevention. It includes 6 levels of increasing scope for developing multifaceted injury prevention initiatives.12 The levels, from least to greatest scope include strengthening individual knowledge and skills, promoting community education, educating providers, fostering coalitions and networks, changing organizational practices, and the last and highest level of influencing policy and legislation.12 Injury prevention workers can work in all levels through educational outreach and partnership development. Also, Frieden's Health Impact Pyramid applies to injury prevention interventions as it emphasizes broader social factors and making default decisions healthy/safe to decrease injuries.13

Although it is clear that policy skills are very important for injury prevention workers, there has not been a broad-based exploration of these workers' perceived importance and skill levels related to policies and policy making to determine whether continued successes in the field will occur. Therefore, the purpose of this study is to examine these issues among state injury prevention workers utilizing the Public Health Workforce Interests and Needs Survey (PH WINS) population.14


Sampling and broader survey methodology have been published elsewhere.14 In brief, PH WINS was fielded in fall 2014 to gauge public health practitioners' perspectives on workplace environment, job satisfaction, national trends, and training needs, and to gather demographics on the workforce. PH WINS was fielded in 3 frames—a nationally representative frame of state health agency staff; staff from a group of large, urban local health departments; and staff from other, smaller local health departments. This study utilizes data from the state health agency frame only, focusing solely on those permanently employed, central office staff. For PH WINS, respondents were sampled from 5 paired Health and Human Services regions. Approximately 25 000 invitations were sent to central office employees. After accounting for invalid e-mail addresses and staff who had left their positions, the response rate was 46% (n = 10 246). Balanced repeated replication weights were used to construct robust variance estimators and account for the complex sampling design at both the state and regional levels. As a result, weighted percentages will be presented in this article.

The PH WINS instrument primarily comprises previously used or validated questions. It draws heavily from the Centers for Disease Control and Prevention's Project Officer Survey, the 2009 Epidemiology Capacity Assessment, the Federal Employee Viewpoint Survey, the Public Health Foundation Worker Survey, and the Job in General Scale.15–20 Questions were added relating to training needs and awareness of national trends. Comprehensibility and accessibility of the survey instrument were assessed through cognitive interviews with state and local health department employees, with special emphasis on newly constructed questions and scales.

The data reviewed in this article are based on the 3 policy-related questions and responses to PH WINS and are categorized in a similar manner as described by Castrucci et al.4 This article focuses solely on the state governmental public health workforce. Excluded from these analyses were employees in program areas other than injury and those with nonprogrammatic roles such as clerical and custodial staff, providing us with a total of 97 respondents. When weighted, this resulted in an estimated population size of 365.

The first question relates to perceptions of the importance of 2 policy-related skills to the day-to-day work of injury prevention specialists. Also assessed was self-reported ability to perform the skill (or not). These skills are “influencing policy development” and “understanding the relationship between a new policy and many types of public health problems.” Gaps in knowledge refer to those who rated an item as somewhat/very important but also indicated that they were “unable to perform” or were a “beginner” at the skill. No gaps in knowledge or proficiency were defined as a self-reported rating of “proficient” or “expert” for those daily work tasks that were somewhat or very important. We also assessed knowledge of, comfort level with, and impact of new national trends on the injury workers' daily work utilizing the HiAP items.

Descriptive analysis with frequencies and weighted percentages were calculated. All analyses were conducted using STATA 14.0. PH WINS was deemed exempt by the Chesapeake institutional review board.


Of the 7261 state public health programmatic employee respondents to the PH WINS survey, 1.3% were injury prevention workers (N = 97). Demographic responses from the survey are found in Table 1. The greatest proportion of workers were between the ages of 26 and 50 years, did not have a public health degree, were in nonsupervisory positions, and had worked in public health for 6 to 20 years.

Table 2 shows weighted perceptions of HiAP for injury prevention workers. The majority of injury prevention workers had heard of HiAP and believed that there should be more emphasis on it (57.8% and 62.26%, respectively). Also, the majority of respondents perceived HiAP to be somewhat or very important to public health (79.37%). However, only about 34% (33.55%) of injury prevention workers reported that HiAP would have a fair amount or great deal of impact on the daily work they do.

Table 3 shows the weighted percentages of injury prevention respondents who reported (1) the importance of influencing policy development to their day-to-day work; (2) the skill level (unable to perform/beginner vs proficient/expert) of those workers who reported influencing policy development as important to their day-to-day work; (3) the importance of understanding the relationship between a new policy and public health problems; and (4) the skill level of those who found the competency to be important to their day-to-day work. Injury prevention workers reported high levels of importance of both influencing policy development and understanding the relationships between a new policy and public health problems in their day-to-day work, yet lower skill levels.

This current study finds that injury prevention workers may benefit from having a greater knowledge of and skills in policy making. Also, there shows need for a better understanding of the HiAP among injury prevention workers in terms of the importance of HiAP on the impact of their work. We found that injury prevention workers report that they understand the importance of policy skills and yet perceive their skill levels to be lower. This could be due to state injury prevention workers' understanding the roles policies have had on the field of injury prevention throughout the years; however, they lack confidence in their ability to serve as change agents. Castrucci et al4 also showed that those staff in environmental health, maternal and child health, communications, and all other areas had greater odds of having the competency (meaning the respondents who felt the skill was somewhat/very important to their day-to-day work and they were proficient or expert at it) of understanding the relationship between a new policy and many types of policy problems than those staff in chronic disease and injury.

As stated earlier, it is not that the field has neglected the importance of policies on injury prevention. In fact, the core competencies developed for injury and violence prevention professionals include policy skills as a major component ( Core competency 7 is the ability to stimulate change related to injury and/or violence prevention through policy, enforcement, advocacy, and education. The learning objectives for this competency provide more specifics such as identifying gaps in policies and laws; identifying potential partners and opponents in influencing policies, laws and regulations; having the ability to work together with advocacy/survivor groups (ie, mothers against drunk driving); and understanding how policy change can have positive or negative effects on injury and/or violence outcomes.

To further address skill gaps, more emphasis should be placed on policy development and evaluation at the federal, state, and local levels for injury prevention professionals. The 10 funded National Center for Injury Prevention and Control's Injury Control Research Centers ( offer opportunities for skill development that could be expanded to perhaps reach broader audiences as does the summer program offered by the Johns Hopkins Center for Injury Research & Policy. In addition to the Injury Control Research Centers, the National Center for Injury Prevention and Control could make available additional webinars and trainings related to policy development and especially HiAP and could develop a train-the-trainer approach where state-level workers could be trained and work with their local counterparts to become more proficient. While schools and colleges of public health are important avenues for education and training, not all injury prevention professionals have or are receiving degrees in public health, nor take classes in these programs. However, these schools and colleges could partner with state programs to link educational opportunities for state staff. Examples include streamed professional presentations, free webinars, and in class or online summer programs and institutes.

Two of the 10 great public health achievements of the 20th century were related to injury prevention—motor vehicle safety and workplace safety.21 These achievements were made possible by leveraging policy and regulations to increase uptake of new knowledge and innovations in protecting human lives and health that contributed to environments in which health could be prioritized. Therefore, continued growth in policy development knowledge and skills is essential for injury prevention workers.

Limitations of this research include that the responses are derived from a cross-sectional survey that shows associations and not predictions. However, the findings are suggestive of training needs in the injury prevention area. Also, the results have been weighted to state injury prevention workers for comparability.

Implications for Policy & Practice

  • The success of several injury prevention efforts has involved policy changes and enforcement, and state injury prevention workers should be among the strongest advocates.
  • Continued gains, given reductions in the size and funding of the public health workforce, will rely on policy and regulatory interventions.
  • Without proper training, the likelihood of maintaining the gains that have been achieved or forging new gains is small.
  • Continuing to ensure that the injury prevention field can have successes on the basis of policy and regulatory changes will require investment to ensure that the policy skills and capabilities of state injury prevention workers are developed and enhanced.
