The control group underwent routine training, while the observation group underwent a 12-week positive psychological intervention based on the \u201cThree Good Things\u201d program. The Core Self-Evaluation Scale, Patient Health Questionnaire Depressive Symptom Cluster Scale, Generalized Anxiety Disorder Scale, and resting-state functional magnetic resonance imaging were used for data collection pre- and post-intervention. The amplitude of low-frequency fluctuation, fractional amplitude of low-frequency fluctuation, and regional heterogeneity indices were calculated to assess the functional brain activity of the participants. Pearson\u2019s correlation coefficient was used to assess the relationship between the changes in brain function and behavior.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was no difference in the general information of the two groups pre-intervention. Post-intervention, the observation group reported higher self-evaluation scores and lower anxiety and depression scores than the control group. The amplitudes of low-frequency fluctuation of the observation group were significantly higher than those of the control group in the bilateral calcarine gyrus, left cuneus lobe, left supramarginal gyrus, left middle temporal gyrus, left inferior frontal gyrus, left inferior parietal lobe, right superior parietal lobe, right angular gyrus, and right middle temporal gyrus.
