When comparing psychological instruments like the Center for Epidemiological Studies-Depression Scale (CES-D) and the Positive and Negative Affective Scale (PANAS), the tedious and complex harmonisation process is often a key challenge for researchers. Harmony, with its natural language processing and generative AI models, plays a vital role in simplifying this process. With CES-D vs PANAS being a frequent comparison in psychology research, Harmony could revolutionise the way researchers approach their data coherence. Harmony’s innovative system uses large language models to compare the individual items in CES-D and PANAS, providing a percentage match result. The CES-D vs PANAS comparison becomes more manageable, objective and less time-consuming with Harmony. Beyond this, the tool’s underlying technology allows its usage in multilingual contexts, allowing for meaningful comparisons even when different languages are used in the questionnaires. This opens new research possibilities into cross-cultural psychology research. To researchers working with CES-D vs PANAS, or similar scale comparisons, Harmony is a significant tool to consider. It centralises and accelerates the harmonisation process, increases objectivity, and enhances the comparability of results within and across studies. By visiting https://harmonydata.ac.uk/app, researchers can drag and drop their PDF questionnaires onto the platform and efficiently harmonise their questionnaire items. This allows psychologists to avoid repetitive and tedious manual work, freeing up time to focus on their analyses.
