Software Psychologists and social scientists often find themselves needing to compare different questionnaires or instruments as part of their research studies. This includes comparing the Patient Health Questionnaire-9 (PHQ-9) versus the General Health Questionnaire-28 (GHQ-28). This process, referred to as harmonisation, while necessary, can sometimes be quite laborious and subjective. Thankfully, Harmony, a software developed specifically for psychologists, streamlines this process through the use of natural language processing and generative AI models. Harmony is not just a time-saving tool for comparing PHQ-9 vs GHQ-28 but an innovative solution that enables a deeper level of analysis. By computing a percentage match between each item in PHQ-9 and GHQ-28, Harmony ensures greater accuracy and objectivity in the harmonisation process. It also supports multiple languages, broadening the scope of studies and making it easier to compare instruments from different cultural contexts. To fully reap the benefits of the software, psychologists can either select instruments from Harmony’s extensive database or upload their own instruments in PDF format via the web interface. Therefore, when dealing with PHQ-9 vs GHQ-28 comparison, Harmony is definitely a go-to solution.
