 This study examined the psychological situation of high school students in China by analyzing their subjective well-being, SWB. The results showed that the average age of the students was 16.32 years old and the average SWB score was 76.68. The distribution of SWB between male and female students was significantly different, p less than 0.001. The strongest node in the network was S8, have you been anxious, worried, or upset, which had the highest strength and expected influence? All nodes were positively correlated with each other, p less than 0.01. The network structure and centrality remained stable after discarding 75% of the sample at random. Targeting S8, have you been anxious, worried, or upset, as a potential intervention target may increase high school students' SWB effectively?
