This study explores how machine learning-based computerized adaptive testing (ML-MT-CAT) can revolutionize mental health assessment by tailoring tests to individuals and accurately tracking changes over time.
Machine Learning-Model Tree-based Computerized Adaptive Testing (ML-MT-CAT) was evaluated to provide adaptive symptom assessments for anxiety, depression, and social anxiety, achieving estimations comparable to full-length tests with over 50% item reduction.
The research involved 564 participants, primarily Spanish university students, and was conducted by authors from various institutions, including Universitat Jaume I.
The data was collected over four time points at 6-month intervals from February 2018 to December 2019.
The research took place primarily at the Universitat Jaume I, Spain.
Traditional mental health assessments can be cumbersome and lead to unreliable results, with ML-MT-CAT aimed at improving efficiency and accuracy without overburdening patients.
The study used real data simulations and cross-validation methods to compare ML-MT-CAT with static full-length assessments to measure mental health traits.
ML-MT-CAT showed strong agreement with traditional tests, outperforming shorter static measures.
