The Reliability and Applicability of the Physical and Mental Health Promotion Model for Adolescent in Different Social Contexts

To examine Physical and Mental Health Promotion Model for Adolescent in Different Social Contexts, 1073 sets of survey data per year were randomly selected from databases during the period of the normalization prevention and control, the outbreak of COVID-19, and the lifting of social controls for COVID-19. The average score of sleep duration(SD) for adolescents was 440.15, 430.14, and 441.80 minutes/day respectively (F = 9.62, p < 0.001), physical activity level(PAL) was 2.54, 2.35, and 2.46 respectively (F = 18.87, p < 0.001), general self-efficacy (GSE) was 2.65, 2.36, and 2.71 respectively (F = 74.53, p < 0.001), and mental health (MH) was 1.54, 1.86, and 1.57 respectively (F = 87.31, < 0.001); ANOVA results showed significant differences. There were significantly correlated with each other among average score of PAL, SD, GSE and MH. The total effects of the model were − .196, − .338, and − .221, respectively, all with P < 0.001; the direct effects were − .089, − .230, and − .117, respectively, all with P < 0.001; the total indirect effects were − .107, − .107, and − .104, respectively; with PAL→SD→MH was − .077, − .051, and − .063, and PAL→GSE→MH was − .031, − .057, and − .041, all with a significant meaning in the Bias-Corrected 95%CI test. However, during the COVID-19 outbreak, few fit indices of the model did not reach ideal values. SD and GSE play multiple mediating roles in P hysical and Mental Health Promotion Model for Adolescent , which is effective. However, in critical social situations, more attention should be paid to the direct effect of PAL on MH.
