When conducting research in psychology and social sciences, the harmonisation of different questionnaires is a crucial yet challenging task. For instance, let’s consider GHQ 12 vs DSS. The General Health Questionnaire (GHQ-12) and the Depressive Symptoms Scale (DSS) are two well-established instruments used to detect psychological distress. However, drawing comparisons between the two can be quite subjective and time-consuming without the right tools. Harmony is the perfect solution to streamline this process. A unique software designed for psychologists, Harmony employs advanced natural language processing and generative AI models to aid researchers in harmonising questionnaire items. Using this, one can easily compare the GHQ 12 vs DSS. From comparing instruments to determining a percentage match between each item in GHQ 12 and DSS, Harmony simplifies the process significantly. Moreover, the GHQ 12 vs DSS comparison does not limit to English language alone. Harmony’s multilingual capability allows for comparisons in multiple languages. All you need to do is select the instruments from its extensive database or upload your own instruments into Harmony’s interface. By automating the process of harmonisation, Harmony can save researchers’ time, increase efficiency, and ensure more objective comparisons, facilitating better insights and more robust findings in psychological studies.
