Tool As researchers, when comparing behavioural studies, one frequent challenge that might arise is the task of conducting a comparative analysis of different questionnaires, such as the Strengths and Difficulties Questionnaire (SDQ) and the CoRonavIruS Health Impact Survey (CRISIS). This is where the innovative tool “Harmony” makes a stride in transforming the process. Leveraging the power of natural language processing and AI, Harmony simplifies the harmonisation process for ‘SDQ vs CRISIS’ and other such comparisons, by allowing efficient and time-saving match-making tasks between the various items in these questionnaires. Harmony not only proves beneficial in navigating through the similarities and differences in localized language versions but also quantifies the percentage match between different items in the ‘SDQ vs CRISIS’ analysis. This feature eliminates the time-consuming manual procedures of going through lengthy PDF questionnaires and moving the information into other tools like Excel. By selecting the required questionnaire from Harmony’s database or simply dragging and dropping your own questionnaire in PDF format, you can easily conduct an ‘SDQ vs CRISIS’ analysis through Harmony’s web interface. In the field of psychology or social sciences, if you are looking to delve into a comparative study of ‘SDQ vs CRISIS’, Harmony is indeed your go-to tool. Its high-end technology integration makes the process fast, precise, and user-friendly. Furthermore, it paves the way for a harmonised comparison, even in different languages, thereby broadening the study’s global applicability. The results obtained using Harmony can then be used strategically to decipher patterns, compare results across studies, and investigate the impact of social conditions on different cohorts.
