Screening for Depression and Anxiety Using a Nonverbal Working Memory Task in a Sample of Older Brazilians: Observational Study of Preliminary Artificial Intelligence Model Transferability

Screening for Depression and Anxiety Using a Nonverbal Working Memory Task in a Sample of Older Brazilians: Observational Study of Preliminary Artificial Intelligence Model Transferability

To evaluate the transferability of predictive power from two models (depression and anxiety screening) developed using the thymia internal dataset using n-back features to the older Brazilian population, we tested on the Laços Saúde patient cohort. Specifically, we chose models designed to classify depression and anxiety based on thresholds defined by PHQ-8 scores ≥10 and GAD-7 scores ≥10, respectively. The test results, depicted in terms of the AUC, can be found in Figure 3.
