Exploring Data Harmonisation: Harmony's Role in Advancing Mental Health Research

In the dynamic world of mental health research, Harmony emerges as an innovative tool, helping researchers to integrate diverse datasets to reveal significant insights. Developed collaboratively by Ulster University, University College London, the Universidade Federal de Santa Maria, and Fast Data Science, Harmony was awarded the prestigious Wellcome Mental Health Data Prize for its significant contributions. 

Transforming data integration, Harmony enables researchers to upload mental health questionnaires in PDF or Excel formats, including the GAD-7 anxiety questionnaire. Employing transformer neural network architectures, Harmony identifies identical, similar, or contrasting questions among questionnaires, generating insightful network graphs for harmonising datasets. This unique approach transcends linguistic barriers, facilitating multilingual data harmonisation. 

Harmony seamlessly integrates with the Catalogue of Mental Health Measures, which serves as a comprehensive repository for mental health and wellbeing measures from close to 60 British cohort and longitudinal studies. Through Harmony’s utilisation of the Catalogue’s data via its API, users can seamlessly transition from Harmony to the Catalogue to explore mental health measures more deeply. Currently, the Catalogue, Harmony, and LLC are jointly seeking funding to integrate their platforms, with the goal of enabling Catalogue users to transition effortlessly to Harmony. The Catalogue of Mental Health Measures plays a crucial role in the FAIR Curated Mental Health Data core activity at DATAMIND, emphasising its dedication to data discoverability and accessibility, and collaborative projects. With thousands of mental health measures from UK longitudinal studies, the Catalogue facilitates the exploration of indicators related to mental health problems, treatment, and overall wellbeing. In tandem with the Data Core Activity at DATAMIND, which upholds FAIR principles, this initiative fosters transparency and collaboration within the mental health research community. 

Led by Dr. Eoin McElroy from Ulster University and Dr. Bettina Moltrecht from University College London, Harmony’s development aims to promote better integration of data harmonisation in mental health research. This facilitates investigations into the active ingredients of mental health and addresses critical questions surrounding human connection and its impact on depression and anxiety development in young people. 

In summary, Harmony represents a significant leap forward in mental health research. Through innovation and collaboration, this tool enables researchers to deepen our understanding of mental health and improve outcomes for everyone.
