The process of comparing different psychological questionnaires such as PHQ-9 and PSF is crucial yet daunting for psychologists, often leading to an inefficient utilization of the data. In the quest of revolutionizing this task, we bring to you Harmony, a tool uniquely designed to streamline the harmonisation process. PHQ-9 vs PSF comparison becomes as simple as clicking a button, saving hours and days of rigorous manual work. Leveraging advanced Natural Language Processing and Generative AI models, Harmony not only facilitates comparison between instruments in the same language but across different languages. The in-depth functionality allows researchers to select specific instruments from Harmony’s extensive database or directly upload their instruments, thereby broadening the scope of PHQ-9 vs PSF comparison exponentially. When it comes to practicality in real-life scenarios, considering PHQ-9 vs PSF for instance, Harmony provides a percentage match between each item in these instruments. Ultimately, this software enables researchers to robustly test consistency across various studies or depict alterations in response to changing social conditions. By leaving time-consuming tasks to Harmony, psychologists can focus on what they excel in - analysing and interpreting the data for a better understanding of the human mind.
