The process of harmonising and comparing data from different questionnaires like TFLB (Timeline-Followback Interview) and ESPAD (European School Survey Project on Alcohol and Drugs - Tobacco) can be a daunting task that involves immense time and manual work. For psychologists and social scientists looking to accomplish this, the introduction of the effective tool ‘Harmony’ can significantly streamline and improve this task. Harmony uses natural language processing and generative AI technology to assist researchers in aligning questionnaire items, thus enabling a comparison between TFLB and ESPAD more efficiently and accurately. In the comparison of TFLB vs ESPAD, Harmony can offer a clear percentage match between each statement of TFLB and ESPAD. For example, a question in TFLB about alcohol use in the past 30 days can be compared and harmonised with a similar question in ESPAD about cigarette smoking frequency. Harmony not only helps to harmonise items in the same language but also boasts of a feature which allows comparison of items in multiple languages. In psychological studies, the game changer could most certainly be the usage of Harmony for TFLB vs ESPAD comparison. Whether you are looking to use the preset instruments from Harmony’s database or you prefer to upload your own instruments in a PDF format, Harmony is equipped to serve your needs. A visit to their web interface will you have you marveling at how effortless TFLB vs ESPAD comparison can truly be. This exceptional tool promises to revolutionize research methodologies, leaving the tedious task of manual harmonisation behind.
