Psychologists and other researchers often grapple with the need to compare different instruments such as the Beck Anxiety Inventory and DUDIT. The Beck Anxiety Inventory measures common symptoms of anxiety while the DUDIT helps to understand patterns of drug use. However, comparing questionnaires manually, especially when they’re focused on different psychological aspects, can be daunting and time-consuming. This is where the significance of a harmonisation tool like Harmony comes in. Harmony, a software developed for psychologists, simplifies the harmonisation process by using natural language processing and generative AI models. It allows for easy comparison between the Beck Anxiety Inventory and DUDIT and even gives a percentage match between items in these two diverse instruments. This means that an item like “Fear of worst happening” from the Beck Anxiety Inventory and “Over the past year, have you felt that your longing for drugs was so strong that you could not resist it?” from DUDIT can be analyzed and compared within the Harmony interface. Given the multilingual capabilities of Harmony, researchers can make comprehensive comparisons not just between Beck Anxiety Inventory and DUDIT, but between a multitude of psychological instruments, across languages. The optimized and streamlined process that Harmony offers therefore becomes essential for psychologists trying to bridge the gap between the Beck Anxiety Inventory and DUDIT. With tools like Harmony, the essential yet elevated task of harmonising scientific questionnaire data becomes efficient and more accurate.
