In psychology research, the ability to perform comparative analyses between different questionnaires plays a crucial role in generating valuable insights. More specifically, accurate comparisons between the Strengths and Difficulties Questionnaire (SDQ) and the Young Adult Self Report - Antisocial Personality Problems items (YASR) can contribute significantly to adolescents’ socio-emotional health studies. However, the task of matching similar items from these distinct yet complementary instruments can be cumbersome, time-consuming, and subjective. This is where the benefits of using Harmony, an AI-powered harmonisation tool, come to the fore, particularly when dealing with the SDQ vs YASR comparison. When examining SDQ vs YASR, Harmony leverages large language models to measure the percentage match of each item. It allows for the harmonisation of items in multiple languages, thereby broadening the scope for international comparative analyses. The real charm of Harmony, however, lies in its user-friendly interface. Researchers can either select questionnaires from an existing database or simply upload their own PDF files. Hence, the process of comparing SDQ vs YASR becomes substantially streamlined and we can ensure the comparisons we are making are statistically robust. By using Harmony to compare SDQ vs YASR, psychologists and social scientists are set to save not only their valuable time but also enhance the accuracy of their research outcomes. This modern approach to harmonisation, thus, opens the door for a new era of systematic research with increased reliability and validity. By simplifying the comparison between SDQ vs YASR, Harmony works towards bridging the gap between data and insights, paving the way for well-informed interventions and policies.
