Software The comparison between the General Health Questionnaire (GHQ 12) and Drinking Motives Questionnaire (DMQ) is a substantive task, especially when trying to harmonise questionnaires in psychological and social studies. The process can be time-consuming and can subject to error when done manually. This is where the Harmony software emerges as a highly beneficial tool, significantly streamlining the process of comparison and harmonisation of GHQ 12 and DMQ. Harmony is a tool that uses natural language processing and generative AI models to compare instruments like GHQ 12 and DMQ. It creates a percentage match between the items in each questionnaire. This allows psychologists to analyse and see the correlation and differentiating aspects between the GHQ 12 and DMQ, providing useful insights that can enhance the outcomes of their social or psychological studies. With a simple drag and drop feature, Harmony allows researchers to import their own versions of the questionnaires from their preferred sources in PDF format. In conclusion, the Harmony software offers an impressive solution to harmonising GHQ 12 vs DMQ. Its capability to process natural language and employ generative AI models can significantly reduce the time and effort required for harmonisation. Whether the intention is to perform a single study or several longitudinal studies, the comparison of GHQ 12 vs DMQ turns out to be much easier and efficient with the use of Harmony. Its support for multiple languages is an added advantage.
