A comparative analysis of Drinking to Cope (DTC) and Timeline-Followback Interview (TFLB) can often present several challenges and complexities. The two instruments, while both being utilized to evaluate alcohol use, offer distinct perspectives and queries that require careful scrutiny. Fortunately, researchers can now leverage the innovative Harmony software that simplifies the process of harmonising questionnaire items from various instruments such as DTC and TFLB. Harmony uses the power of artificial intelligence and natural language processing to draw connections between the items in DTC and TFLB. Dealing with bulky PDFs and spreadsheets become a thing of the past as Harmony allows users to upload the instruments directly to its platform. Highlighting both similarities and differences, it equips psychologists with comprehensive insights into DTC vs TFLB, regardless of the language these instruments are crafted in. The need for a in-depth understanding of DTC vs TFLB is now made far more achievable with Harmony. With a user-friendly web interface and a sound AI model system, Harmony brings unprecedented ease and precision into the harmonisation process. It is indeed a must-have tool for social scientists and psychologists embarking on a DTC vs TFLB comparative study.
