Changes in Mental Health of Members of the Chinese Army (1990~2007): A Cross-Temporal Meta-Analysis

This study, by using 142 groups of data from 1990 to 2007 and the method of cross-temporal meta-analysis, researched the changing trend of status of mental health of 108736 members of the Chinese Army along with the change of years. All the data came from 94 related research reports, and all the research reports used SCL-90 (the Symptom Checklist 90) as the testing tool of mental health. The study found that: (1) mental health of members of the Chinese Army steadily improved between 1990 and 2007; (2) during those 18 years, the Interpersonal Sensitivity factor of SCL-90 of Chinese Army members changed most significantly, and the least significantly changed factor was Somatization; (3) Chinese Army members showed evidence of fewest problems on the Photic Anxiety factor, in contrast to the consistent problems indicated by scores on the Obsessive-Compulsive and Interpersonal Sensitivity scales; (4) Chinese Army members from single-child families (N =1,944) showed significant lower evidence of positive mental health than soldiers from multiple child families (N =2,649); (5) The mental health of soldiers from non-agricultural backgrounds (N =7,808) was less positive than that of soldiers from agricultural households(N =11,459); (6) Chinese Army members with senior high school education level (N = 10,189) had less positive mental health than those with junior high school (N = 8,407) or university education (N = 863)
