When addressing behavioural and mood concerns in children, two questionnaires become preeminent tools; the Strengths and Difficulties Questionnaire (SDQ) and the Infant Characteristics Questionnaire (ICQ). These two powerful instruments serve crucial roles in guiding psychologists and clinicians in their decision-making process. For a clear understanding and comprehensive comparison, SDQ vs ICQ should be viewed through Harmony, an advanced software with natural language processing and generative AI models providing an efficient and accurate harmonisation process. Harmony leverages large language models to make a comparison between the instruments, providing a percentage match for each item in SDQ vs ICQ. This feature not only saves time but also reduces the chance of error while carrying out the harmonisation process manually. Using Harmony for SDQ vs ICQ comparison will enable researchers, clinicians, and educationalists to make more confident judgements based on critical behavioural and mood indicators in these questionnaires. As an added advantage, Harmony has a multilingual feature, which presents an opportunity to compare items of SDQ vs ICQ in multiple languages. This unique aspect ensures no barrier in the understanding of these critical tools, providing seamless integration in diverse contexts.
