The invention discloses a group inter-person relationship quality evaluation and intervention method and system based on a go/no-go test task. The method comprises the following steps: establishing a double-person go/no-go electroencephalogram experiment multi-test-time test task; carrying out double-person cooperation task testing in the group in turn, recording testing data, and collecting electroencephalogram signals in the task completion process synchronously; extracting test data and electroencephalogram signal data, calculating a task performance index and an electroencephalogram index, and performing classified prediction of the double-person relationship quality level through a machine learning classification model in combination with self-reported relationship quality data; and extracting paired subjects of which the relationship quality levels are lower than a predetermined level in the group, performing intervention, and ending the test task until the relationship quality levels of all the paired subjects in the group reach the predetermined level, thereby obtaining a group relationship quality evaluation score. According to the invention, a real-time feedback relation quality closed-loop training system is established, and the purpose of self-adaptive training is achieved in combination with modes of cognitive tasks, electroencephalogram signal analysis, machine learning, self-adaptive feedback and the like.
