Conducting a comparative analysis between different psychological instruments can be quite challenging, especially when each uses different terminologies and question formats. This is where a tool like Harmony comes in handy. Harmony offers an efficient way to conduct side-by-side comparison between multiple test instruments, for instance, between the Center for Epidemiologic Studies Depression Scale (CES-D) and Psychotic-Like Symptoms questionnaire (PLIKS). The CES-D vs PLIKS comparison will allow psychologists to understand if both questionnaires are capturing similar aspects of mental health or if they supplement each other in different ways. # Why Use Harmony for CES-D vs PLIKS Harmony employs advanced techniques such as natural language processing and generative AI models which allow for thorough and objective comparison between questionnaire items. It can work on versions of these questionnaires in multiple languages too thereby offering a wider applicability. Additionally, it can provide a percentage match between each item in CES-D and PLIKS. This can save researchers substantial time and effort in manual comparison and ensure a more accurate CES-D vs PLIKS comparison. # How to Use Harmony for CES-D vs PLIKS To use Harmony, researchers just need to select these instruments from Harmony’s database or upload their own versions in PDF format via Harmony’s intuitive web interface. Once the relevant instruments are selected or uploaded, Harmony will undertake the evaluation and provide matching percentages for each item in a clear and concise manner. Given the convenience and accuracy Harmony offers in conducting CES-D vs PLIKS comparison, it is an essential tool for psychologists and social scientists targeting a more robust analysis of mental health surveys.
