In recent years, many stress-related health problems have been reported, and an estimated 50% of suicide victims suffered from mental disorders. The State-Trait Anxiety Inventory (STAI), which measures trait and state anxieties, is one of the most widely used questionnaires for mental health, counseling, and research. However, because the STAI is a questionnaire-based test, examinees could manipulate the answers. Therefore, research has been conducted to estimate the state anxiety score, a stress evaluation index, based on brain activity. In the proposed method, Granger causality was used for cerebral blood flow to enable the numerical representation of the complex and diverse behaviors of the brain as dependencies. The brain activity interdependence network (BAIN) was constructed as a network representing the characteristics of brain activity affected by trait anxiety, and the amount of Kalbach – Leibler divergenceon obtained from the BAIN was used as a feature value. In the validation experiment, we measured resting-state cerebral blood flow using NIRS wearable optical topography in 17 male and female subjects in their 20s. Lasso regression analysis was used to estimate the characteristic anxiety score in the STAI, resulting in a correlation coefficient of 0.95 and an RMSE of 3.0 with high accuracy.
