The invention relates to the technical field of psychological assessment, in particular to a
psychological health assessment method based on VR (
virtual reality), which comprises the following steps: based on virtual scene event nodes, analyzing event types, interaction states and priorities, screening adaptive nodes, adjusting an acquisition window, judging amplitude variation of
brain waves, identifying segmentation moments, and combining extreme values and response intervals. And matching a high-risk reference, and classifying psychological risk indexes. According to the method, through
dynamic mapping of user interaction behaviors and virtual situation events, whole-course closed-loop management of data streams is achieved, an acquisition window is adjusted in a linkage mode according to multi-source parameters,
signal segmentation is defined in real time according to actual brain
wave motion and a scene cognitive state, brain wave extreme values and behavior
response time sequences are synchronously extracted, and
coupling analysis is conducted on multi-dimensional features; dynamic grouping of psychological risks is jointly set based on multiple index intervals, timeliness guarantee is obtained for data in a high-frequency interaction scene, and an
evaluation result can reflect continuous evolution of psychological states of a user in a complex environment.
