In psychology and social sciences, the comparison of scales like the SDQ (Strengths and Difficulties Questionnaire) and IRI (Interpersonal Reactivity Index) is a common practice. Such comparisons or “harmonisation” can aid researchers in understanding the similarities and differences across studies, allowing for more robust and comprehensive conclusions. Yet, the traditional process of harmonisation of items from these tools is a tedious and subjective task. The SDQ vs IRI comparison, for instance, would involve painstakingly matching items between these scales, which can be time-consuming. This is where Harmony comes into play. Harmony is an innovative software developed specifically to assist with this process. Utilising natural language processing and generative AI models, it greatly simplifies this harmonisation process. With Harmony, the SDQ vs IRI comparative analysis becomes a walk in the park. The software offers an excellent feature permitting users to select instruments from its database or upload their own in the form of PDFs. Furthermore, it is capable of comparing items in multiple languages, empowering researchers to examine questionnaires across several languages. So, if you find yourself dreading the SDQ vs IRI task, give Harmony a try. This intelligent tool not only automates the matching process but also provides a percentage match between each item in SDQ and IRI, turning a laborious task into an efficient one.
