Objective      To establish the norm (2016 Edition) of Symptom Check List 90 (SCL-90) for Chinese military personnel

which is to provide theoretical basis and practical support for military psychological assessment as well as mental health education. Methods      Through the method of stratified cluster sampling

53 847 military members recruited from the Army

Navy

Air Forces

Rocket Force and Strategic Support Force were surveyed with the SCL-90. SPSS 18.0 was used to establish a corresponding norm by using t-test and One-Way Analysis of Variance (ANOVA). Results      ①The incidence of psychological problems in military personnel was 29.7%. Female soldiers had a significantly higher rate than the males (36.5% vs 28.6%); ②The established norm based on current research differed remarkably from the 1999 Edition (P0.01)

but it had no significant difference compared with the sample of 2005; ③The norm of SCL-90 for military personnel showed different scores with respect to the factors such as gender

military services and personal rank

presented with a higher level of mental health in male soldiers

members of the Strategic Support Force and cadets.  Conclusion       The established norm of SCL-90 (2016 Edition) for Chinese military personnel is adapted to the age and associated with factor difference.
