About this Research Topic

Background

Major depressive disorder (MDD) starts at an early age and is associated with recurrent episodes. It affects more than 5% of the general population and is associated with significant suicide risk. This lifelong illness significantly impacts the patient and their relatives beyond its economic losses. Although we have different treatment options for MDD, the remission rate is almost 50% in the long term with multiple treatment trials. Therefore, one of the ultimate goals of psychiatry is to identify high-risk individuals and use preventive measures before the pre-disease pathophysiology progresses to illness. Although some studies suggest high-risk individuals for MDD have similar biochemical and neuroimaging findings to individuals with depression, others suggest different patterns of the disease process in high-risk individuals. Focusing on high-risk factors in high-risk populations therefore also allows for the identification of factors that promote resilience to depression in those individuals.

The objective of this Research Topic is to establish a dedicated platform addressing high-risk studies related to major depressive disorders (MDD) and related conditions. Our primary focus is on the exploration and characterization of individuals with high-risk for MDD. We invite contributions in the form of research articles, reviews, and meta-analyses spanning various domains, including epidemiology, neuroimaging, genetics, and related fields. While no tailored treatments currently exist for high-risk groups, our intention is to delve into potential psychotherapeutic interventions.

We warmly welcome original research or review articles from scholars across diverse disciplines, including neuroscience, psychology, psychiatry, genetics, epidemiology, and public health. Submissions may encompass:

- Investigating the influence of early life experiences on the risk of developing major depressive disorder.
- Assessing the role of brain structure and function in the development of major depressive disorder.
- Exploring neurochemical imbalances in relation to the development of major depressive disorder.
- Investigating the genetic factors contributing to the development of major depressive disorder.
- Examining psychological factors such as personality traits and coping mechanisms in the context of major depressive disorder development.
- Presenting innovative methodologies for identifying and assessing high-risk groups prone to major depressive disorder.
- Proposing interventions aimed at preventing or delaying the onset of major depressive disorder in high-risk populations.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

• As a junior researcher, can I be involved in editing a Research Topic? 

  If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

• Can I get a certificate for editing a Research Topic?

  Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
