The comparison between Beck Anxiety Inventory (BAI) and Fagerstrom Test for Nicotine Dependence (FTND) instruments involves the harmonisation of distinct questionnaire items. Beck Anxiety Inventory vs FTND can be a time-consuming and complex process due to the individual characteristics of each tool. Beck Anxiety Inventory is designed to measure common somatic and cognitive symptoms of anxiety, while FTND assesses nicotine dependency level. With the aid of Harmony, a software specially designed for psychologists and social scientists, the process of harmonising and comparing Beck Anxiety Inventory vs FTND becomes simpler and more efficient. Harmony uses state-of-the-art natural language processing and generative AI models to compare instruments. By doing so, it significantly reduces the time required for the conventional harmonisation process, which often requires manual data matching and entry. It integrates a simple to use web interface, which allows users to select instruments directly from its database or upload their own in PDF form. When comparing Beck Anxiety Inventory vs FTND, Harmony can give a percentage match between each item and its corresponding pair in different languages. In conclusion, the use of Harmony in the comparison of Beck Anxiety Inventory vs FTND has the potential to revolutionize the way psychologists and social scientists conduct research. By automating the harmonisation process, Harmony ensures that comparisons across different studies can be made with greater accuracy and speed. Its ability to process and match items in multiple languages further enhances its utility to the worldwide community of researchers.
