Choosing the right psychological measure can be a complex task, often involving deep comparative analysis between different questionnaires such as CES-D vs IRI. CES-D (The Center for Epidemiological Studies-Depression) assesses symptoms associated with depression, while the Interpersonal Reactivity Index (IRI) helps gauge empathy within a person. These two scales, while each with their unique forte, might pose a challenge when it comes to comparing and harmonising their items. This is where Harmony steps in. The AI-powered software offers an efficient solution to streamline the harmonisation process. With its capabilities of using natural language processing and generative models, it can match and compare items from various instruments, including CES-D vs IRI. Harmony’s intuitive and user-friendly interface allows researchers to either select from its vast database or upload their own instruments in PDF format. What sets Harmony apart is its multilingual support, making it a versatile tool when dealing with international studies. With a core mission to simplify comparative analysis for researchers, Harmony is the ultimate tool in analysing CES-D vs IRI, or any other combination of instruments. It lets psychologists put aside their mundane manual tasks, while it does the heavy lifting of aligning and matching the research data automatically.
