The field of psychology continually demands deeper analysis and interpretation of data. A common undertaking in this arena includes the comparison of various psychological questionnaires such as CES-D and CTS. The Center for Epidemiological Studies-Depression (CES-D) is a globally recognized instrument for measuring depressive symptoms. On the other hand, the Conflict Tactics Scale (CTS) measures the nature and extent of conflict resolution strategies in relationships. The comparison of CES-D vs CTS can yield interesting insights into the correlation between depressive symptoms and conflict behaviour patterns. Harmony introduces a tech-savvy approach to facilitating this comparison. It leverages the power of natural language processing and generative AI to harmonise questionnaire items, making the comparison of CES-D vs CTS more streamlined and less time-consuming. An exciting feature of Harmony is its ability to compare instruments and provide a percentage match between each item in CES-D and CTS. This simplifies the often tedious task of data harmonisation in psychology, making Harmony an invaluable tool for researchers. In the era of digital technology, psychology research methodologies like CES-D vs CTS comparison need to be aligned with smart, technology-driven tools like Harmony. Researchers can easily select instruments from Harmony’s database or import their own in PDF format, expediting the process of harmonising data across multiple studies. Importantly, Harmony supports multi-language data, catering to researchers globally. As such, Harmony not only simplifies research but fosters global collaboration within the academic community.
