Advancing Biostatistics and Informatics Applications in Mental Health Research

About this Research Topic

Background

Biostatistics development in theoretical and computational methods has grown rapidly in scientific research. Together with health informatics systems that curate multidimensional data at the population level, researchers now enjoy more complex and richer information than ever before to discover and invent new methods, tools, therapies, and medicines for vulnerable populations.

Recent developments in biostatistics have included novel design methods for laboratory experiments and randomized trials, analytical methods for large-dimensional data with a small number of participants, computational methods for data with a hierarchical structure, and analytical methods for systems biology and precision medicine. These developments also involve the use of Bayesian inference to integrate prior knowledge with current evidence.

Recent informatics developments have included novel system design in health informatics for data integration and linkage, enabling cross-system data inferences. For example, from health, sociology, education, and forensic science to solve unsolvable problems with multi-level factors and perhaps for difficult-to-reach or engage populations (i.e., populations experiencing suicide-related distress, Indigenous populations, LGBTQIA+, older people). Biotechnological advancements also facilitate researchers in using e-mental health devices and mobile apps for sensitive data collection and secure data management.

Molecular-focused bioinformatics development is a driving area in precision psychiatry. Bioinformatics methods integrate omics, such as genomics and proteomics, in the discovery of molecular markers for diagnosis and treatment. AI and machine learning have assisted in the discovery and facilitated the emergence of digital biomarkers.

The data curation involved in these research methods should consider ethical AI, algorithmic bias mitigation, Indigenous data governance, and sensitive data governance in the context of mental health. The FAIR (Findable, Accessible, Interoperable, Reusable) data principles are critical for sensitive mental health data and underrepresented populations.


This Research Topic is a collection for mental health research studies using and/or creating advanced biostatistical methods, for observational and randomized control studies, and novel health informatics and bioinformatic methods. The purpose is to encourage more mental health research that utilizes advanced methods of biostatistics and informatics in research design optimization, thereby easing the recruitment process, advancing analytical methods for complex designs, finding solutions to new treatment discoveries, and supporting clinical decision-making.


The Topic Editors welcome submissions of various article types exploring mental health research using health informatics and bioinformatics, focusing on but not limited to:

• Data integration and linkage from the health system

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?
