Psychologists and social researchers routinely have to draw correlations among various questionnaires - a process known as harmonisation. Making such comparisons can be tedious and subjective. Using an innovative software tool like Harmony can significantly simplify this process. A situation where Harmony can be a gamechanger is in the comparison of the Strengths and Difficulties Questionnaire (SDQ) and Three Factor Eating Questionnaire (TFEQ), otherwise known as SDQ vs TFEQ. Harmony leverages cutting-edge AI technologies, such as natural language processing and generative AI models, to deliver precise comparisons between questionnaire items across various studies, even in multiple languages. For instance, when comparing SDQ vs TFEQ, Harmony’s advanced AI models can provide detailed matches between items across these two questionnaires. Thus, driving meaningful insights for researchers and helping them validate or test their hypotheses in a more efficient and effective manner. SDQ vs TFEQ is a comparison that can provide insightful information on a child’s behavioural characteristics and eating habits, respectively. However, the complexity of manual comparison can be extremely overwhelming. Harmony’s cloud-based tool allows researchers to upload their PDF instruments and process them quickly and accurately. Researchers can select from the extensive database of Harmony or drop their instruments in Harmony’s web interface. In conclusion, Harmony not only streamlines the SDQ vs TFEQ comparison process but also takes the burden of manual harmonisation off the shoulders of researchers, unleash the full potential of their research.
