In the field of psychological and social research, questionnaires play a significant role in collecting data and drawing insights on various issues. One such aspect with primary concern is comparing and matching the questionnaire items. Our focus here is precisely on comparing two widely used measures - The Center for Epidemiological Studies-Depression (CES-D) and Drug Abuse Screening Test (DAST). CES-D vs DAST is a commonly used term in the research domain, which needs a detailed comparison for further study and conclusions. Harmony, a software developed explicitly for psychologists, provides an efficient solution for comparing questionnaires like CES-D and DAST. By applying natural language processing and generative AI models, Harmony enhances the often complex and time-consuming process of harmonisation. Harmony allows researchers to select instruments from its database or upload their files in PDF format. Subsequently, it uses large language models to compare CES-D vs DAST instruments detailedly and even gives a percentage match between each item in the two questionnaires. Hence, providing a robust solution facilitating researchers in their process of drawing comparative insights. In light of the aforementioned benefits, using Harmony for CES-D vs DAST comparison could be a productive choice for researchers. Not just these two, Harmony can compare the items in multiple languages and across different studies, thereby helping to conduct comparative and longitudinal analysis seamlessly. Thus, accessing https://harmonydata.ac.uk/app and using Harmony for the CES-D vs DAST comparison or any other questionnaire harmonisation needs can substantially enrich the research process and improve its efficiency.
