The quest to compare and harmonise instruments like the Patient Health Questionnaire-9 (PHQ-9) and the Social Aptitude Scale (SAS) can be simplified using a high-tech tool: Harmony. This innovative, AI-generated software aids researchers by noticeably reducing the time and effort necessary for questionnaire harmonisation. Using a self-explanatory web interface, Harmony effectively compares the core components of PHQ-9 and SAS, finding crucial matches that contribute to a deeper understanding of individual mental health conditions and social aptitude. Perhaps the greatest strength of Harmony when comparing PHQ-9 and SAS lies in its use of natural language processing and generative AI models. Scrutinising the distinctive items of each instrument, Harmony can provide a percentage match; a cutting-edge feature that unifies the questionnaires for refined results. Moreover, allowing users to drag and drop their own instruments in PDF form, Harmony offers customisable comparisons between the PHQ-9 and SAS, creating a flexible and personalised study environment. Undeniably, when striving to understand the intricate connections and disparities between the PHQ-9 and SAS, Harmony becomes an invaluable asset for psychologists and researchers. With its multilingual capabilities, Harmony is not confined to English versions of questionnaires, broadening the scope of potential outcomes. Hence, exploring the interconnection between PHQ-9 and SAS becomes a systematic and efficient process with Harmony, encouraging comprehensive and robust research into mental health and social attributes.
