Comparing psychological measuring tools like the General Health Questionnaire (GHQ-12) and Clinical Questionnaire Short-Form (CQSF) can be a challenging process. It requires meticulous-up-to-date knowledge and a significant investment of time and resources. Here, we introduce a tool that makes this comparison even more accessible and cost-effective — Harmony. With its advanced technology, Harmony offers the potential to transform the comparison process of GHQ 12 vs CQSF. Harmony, modern software developed for psychologists, utilizes natural language processing and generative AI models to harmonise questionnaire items. It benefits from its user-friendly interface where psychologists can drop their instruments, or select from preloaded instruments. Harmony’s advanced language models can compare instruments, giving a percentage match in similarity between items from the GHQ 12 and CQSF. Its capacity extends to multiple languages, making the comparison even more applicable in diverse demographics, a crucial aspect especially when you are looking at GHQ 12 vs CQSF. In conclusion, Harmony presents an exciting development for psychology research. Its application in the comparison of GHQ 12 vs CQSF can lead to more efficient data interpretation, and translate into more accurate analysis and results. This tool is one step forward towards making psychology research even more inclusive and comprehensive.
