Recent years, suicides among middle school students have occurred frequently, which has
attracted broad attention. In this study, depression self-assessment scale, childhood trauma experience
scale, psychological pain scale and open-ended questions were used to investigate the current situation
of middle school students’ suicide crisis, and to explore the social psychological factors leading to
middle school students’ suicide crisis. A total of 876 valid questionnaires were collected from junior and
senior high school students aged 12~18 in Chongqing. SPSS and NVivo were used for quantitative and
qualitative analysis. The results showed that: (1) The degree of depression and despair of middle school
students was significantly correlated with suicide ideation and suicide plan, while psychological trauma
was only significantly correlated with suicide ideation, but not with suicide plan; (2) Suicidal ideation
is related to depression, psychological pain, despair and suicidal behavior; (3) Suicide ideation has
significant differences in depression, psychological pain, psychological trauma, despair, grade, whether
parents are divorced, and whether they are left behind children; (4) The results of qualitative analysis
showed that campus bullying, sex, intimacy crisis and injury were important factors that middle school
students thought would lead to suicidal behavior. In short, the current situation of suicide crisis in middle
school students is not optimistic. The psychological factors that affect middle school students’ suicide
ideation, suicide plan and suicide behavior are different, which is worthy of further study.
