Using PCD’s First-Ever External Review to Enhance the Journal’s Worldwide Usefulness to Researchers, Practitioners, and Policy Makers

Preventing Chronic Disease (PCD) was established in 2004 by the Centers for Disease Control and Prevention (CDC) to enhance the science base on effective public health approaches to prevent and control chronic disease. After 14 years of progress, PCD conducted its first-ever external review to identify ways for the journal to continue to enhance its usefulness for its audience of researchers, practitioners, and policy makers. In June 2017, PCD invited a panel of 7 nationally recognized experts in scientific publishing (Appendix) to respond to key questions about PCD’s mission, quality of scientific content, scope of operation, intended audience, and future direction.

The panel's overall assessment of PCD was that it is well-positioned to continue its trajectory of growth and success. In particular, the panel complimented the journal's leadership, innovation in scientific publishing, increase in national visibility, and superior customer service provided to its editorial board, associate editors, authors, readers, and peer reviewers. On the basis of the panel's recommendations and in consultation with the journal's editorial board, associate editors, and National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) leadership, I am pleased to share these enhancements to the journal.

Refining PCD's Vision and Mission Statement
PCD was encouraged by the external review panel to refine its vision and mission statement. PCD will maintain the journal's focus on providing current, top-quality content to public health practitioners, researchers, and policy makers. PCD vision and mission statements now clearly reflect the journal's commitment to disseminating respected content worldwide.
Vision. PCD will serve as an influential journal in the dissemination of proven and promising public health findings, innovations, and practices with editorial content respected for its integrity and relevance to chronic disease prevention.
Mission statement. The mission of PCD is to promote dialogue among researchers, practitioners, and policy makers worldwide on the integration and application of research findings and practical experience to improve population health.
The opinions expressed by authors contributing to this journal do not necessarily reflect the opinions of the U.S. Department of Health and Human Services, the Public Health Service, the Centers for Disease Control and Prevention, or the authors' affiliated institutions.

Focusing on Topics Areas of Greatest Interest
PCD has been in existence long enough to better focus the primary topic areas of greatest interest to the journal. PCD has refined its primary focus to 4 main areas: Development, implementation, and evaluation of populationbased interventions to prevent chronic diseases and control their effect on quality of life, illness, and death.
• Behavioral, psychological, genetic, environmental, biological, and social factors that influence health.
• Interventions that reduce the disproportionate incidence of chronic diseases among at-risk populations.
• Development, implementation, and evaluation of public health law and health-policy-driven interventions.
• These 4 areas of interest represent areas in which the journal now seeks to expand its content. On its About the Journal webpage, PCD will provide examples of the types of articles and content of greatest interest to the journal under each of these topic areas. Submissions to PCD that merely describe programs, theoretical frameworks, or research or evaluation methods without providing findings supported through sound research or evaluation will not be of primary interest to the journal. In addition, submissions that focus solely on describing partnerships, collaborations, and coalitionbuilding efforts will not be of interest to the journal.

Revisiting Article Types
Moving forward, PCD will strongly encourage the submission of manuscripts that align with the journal's revised mission and areas of interest. Doing so will put the journal's editorial resources to best use. Given that PCD has not received a meaningful number of book reviews for consideration, the Book Review article type has been eliminated. PCD also will eliminate the Special Topics and Community Case Study article types. In their place, PCD will introduce a new article type, Program Evaluation Brief. Program Evaluation Briefs will allow authors to share promising preliminary data and findings based on the use of sound evaluation methods and approaches. An important goal of this new article type is to encourage more submissions from organizations and institutions (eg, state and local health departments, community-based organizations) with findings from well-delivered and evaluated public health programs. PCD also has renamed the Tools and Techniques article type to Tools for Public Health Practice. PCD will keep the following article types: Original Research, Research Brief, Systematic Review, Implementation Evaluation, Essay, and Letter to the Editor. PCD will place greater emphasis on publish-ing Program Evaluation Brief, Implementation Evaluation, Original Research, Research Brief, and Systematic Review article types. PCD will maintain the highest ethical standards in scientific publishing to promote a transparent review and decision-making process for all manuscripts submitted to the journal.

Securing Scientific and Programmatic Expertise
To emphasize PCD's commitment to publishing quality articles from around the world, the journal will add the following statement to the journal's About the Journal statement: "Preventing Chronic Disease (PCD) is a peer-reviewed public health journal sponsored by the Centers for Disease Control and Prevention and authored by experts worldwide." Although supported by CDC, the journal maintains its commitment to a broad representation of public health professionals on its editorial board; of PCD's 23 editorial board members, only one is a CDC employee. Over the past year, PCD has increased the number of associate editors to improve access to specific content areas. PCD currently has 16 associate editors, 9 who are external to CDC and 7 who are CDC employees. The names, titles, affiliations, backgrounds, and appointment terms are available on the journal's website (https:// www.cdc.gov/pcd/about_the_journal/associate_editors.htm). Term limits for all editorial board members and associate editors were established in 2016. We continue to identify new talent and improve succession planning to ensure the journal secures and maintains the necessary expertise.

Complementing Our Work on Epidemiological Studies With Increased Attention to Evaluating Population-Based Interventions and Policies
PCD has developed an international reputation as an authoritative resource, publishing the latest information on the epidemiological effects of behavioral, psychological, genetic, environmental, biological, and social factors that influence health. PCD will continue to serve as primary resource to the world in this area, and we will now increase our focus on disseminating articles that report findings beyond epidemiological studies. PCD will emphasize identifying and securing articles from researchers and practitioners working in settings that improve health by using population-based interventions and policies. Researchers and practitioners are encouraged to submit Original Research, Implementation Evaluation, and Program Evaluation Brief articles to the journal for consideration. Providing Transparent Information on the Journal's Impact PCD will provide transparent information on its website that describes and reports measures used by the journal to determine the quality of the journal's content and the journal's global reach. Multiple metrics will be posted in the journal's annual Year in Review to provide readers with a sense of the journal's relevance, resonance, reach, routine, and recognition:

PREVENTING CHRONIC DISEASE
Relevance: Measure of publication impact by examining the number of PCD citations.

1.
Resonance: Measures of sharing activity that generates attention to create awareness and dissemination. This will include "likes," bookmarks, and media coverage (Altmetric).

2.
Reach: Measures that help examine how far information can travel to help determine popularity, affinity, and potential impact. PCD will track the number of views, downloads, and visitors to its website, and for all published articles.

3.
Routine: Measures that provide insight on processes that ensure publication content aligns with the journal's mission and scope and with the highest publication standards. PCD will report on the number of submissions, rejection rate, acceptance rate, and turnaround times in its annual Year in Review.

4.
Recognition: Measures that rely on citation history to determine the journal's standing in scholarly literature using various systematic approaches. PCD will use impact factor, Scopus, and Google Scholar to help determine the journal's recognition.

5.
Conclusion PCD's commitment to scientific quality and integrity, service to the public, and technological innovation over the past 13 years have led to its respected place in the field of public health. The external review panel was an initiative to continue this success and advance the journal. NCCDPHP's leadership, along with PCD's editorial board, associate editors, and staff remain committed to enhancing the journal's focus, reach, and visibility. Its revised vision, mission statement, and areas of focus better emphasize the journal's commitment to advancing the intersection of research, practice, and policy.
