Researchers, clinicians, and psychologists often need to compare different questionnaires, such as the Strengths and Difficulties Questionnaire (SDQ) and the Toronto Alexithymia Scale (20-item) (TAS-20), for more reliable and comprehensive insights. One of the best solutions to automate this process is “Harmony”, an AI-driven platform designed specifically for questionnaire harmonisation. Using the term “SDQ vs TAS-20”, Harmony’s advanced algorithms work seamlessly to draw matches between the two scales. Harmony uses advanced Natural Language Processing (NLP) techniques and AI models to compute a percentage match for each corresponding item in SDQ vs TAS-20. This functionality not just saves significant time for the researchers but also offers a more objective evaluation. Regardless of the language, Harmony provides a reliable instrument for harmonising items even if the instruments used are in different languages. Encouraging the use of Harmony for “SDQ vs TAS-20” comparison can drastically reduce manual effort and subjectivity, improving the efficiency of the research process. Harmony’s database includes a variety of instruments to select from, but researchers also have the option to upload their own questionnaires in PDF. Experiencing Harmony’s advantage for “SDQ vs TAS-20” comparison will surely pave the way for markedly improved results in psychology research.
