The purpose of the preparation of high school students life events multidimensional assessment questionnaire (Multidimensional Life Events Rating Questionnaire for Middle School Students, MLERQ), and project analysis and the reliability and validity of the questionnaire; analysis of high school students the level of life events and sub-health status, health risk behaviors in detection relationship, verification empirical validity, mental health services and research for secondary school students the basic tools. Method combines literature review, semi-structured interviews, reference the similar questionnaire / scale, the research group discussion method for the preparation of the initial questionnaire; 3732 who started high secondary school students to fill out the initial questionnaire, while taking advantage of the self-rating anxiety scale (Self-rating Depression Scale SAS) and Self-Rating Depression Scale (Self-rating Depression Scale, SDS) to complete the self-assessment of symptoms of anxiety and depression. Integrated use of Student's t test, correlation coefficient, the maximum orthogonal rotation factor analysis and other statistical methods from the deletion of selected sensitivity, independence, effectiveness and internal consistency of the questionnaire entries. Calculated the coefficient of Cronbach'sа and split-half reliability; expert evaluation method to analyze the content validity; construct validity of the factor analysis method; detection of the use of SAS and SDS criterion-related validity. Through to the more psychological statistical analysis, the expert evaluation questionnaire entries deleted and left the final decision to determine the final entry of MLERQ. Taken in a middle school of 114 students to fill in the items deleted after the election MLERQ was 2 weeks after the first subjects were retested to verify the test-retest reliability. Select eight cities of Beijing, Harbin and other cities were selected urban and rural junior high school (the first two days) and urban and rural high school (high school, High School) a convenience sampling method, extracted from each grade 2 small classes, a total of 12,752 students for the study, conducted a questionnaire survey. The survey mainly include the MLERQ youth sub-health multidimensional assessment the questionnaire (Multidimensional Sub-Health Questionnaire of adolescents, MSQA), 1 year self-injurious behavior, within one year of the psychology of suicide behavior and network usage within six months. Using the chi-square test for the level of students' life events, sub-health state, self-injurious behavior, suicide, psychological behavior, network analysis, and the indicators to compare the difference between the different gender and residence, different grades at the same time more these indicators detection rate differences between the different levels of life events. Results of comprehensive statistical analysis of the results and expert opinions, and ultimately the formation of the questionnaire of 43 items of the five dimensions. The test-retest reliability of the questionnaire, the Cronbach's alpha coefficient, split-half reliability 0.891,0.923,0.880; questionnaire has good content validity, anxiety and depression self-assessment score correlation coefficients were 0.435 and 0.512 (P <0.01); Factor analysis showed that the structure of the questionnaire with the same theoretical constructs. The survey results show that in eight cities across the country: school life, family life and peer relationships between events is a major stressor of high school students; life events grouped between the different dimensions of the average detection rate of 34.0%, each dimension packet detection rate differences between the different gender and residence, different grades was statistically significant (P <0.01); physical, psychological, physical and psychological sub-health detection rates were 11.6%, 11.6% and 10.7% ; self-injurious behavior detection rate of 19.9%; the total suicide psychological and behavioral detection rate of 15.0%, of which 13.8% of boys and 16.1% girls; the Internet Addiction detection rate of 10.4%. Somatic health, mental health, physical and mental sub-health, self-injurious behavior, suicidal ideation, suicide plans, suicide attempts, and the incidence of Internet addiction in P73 group differences were statistically significant (P <0.01), rate value increased with elevated levels of life events, The trend of chi-square values ??were 867.92,1 488.32,1 398.68,834.20,148.83,85.94,50.37 and 797.01. Test data stratified by sex, household and grade, the detection rate differences on the different levels of life events still statistically significant, and both increased with increasing levels of life events. Logistic regression analysis showed that low levels of life events (lt; P27) is sub-health, protective factors from the injury and other psychological and behavioral problems, high levels of life events (gt; P73) risk factors. Conclusion rigorous project analysis and reliability and validity, culminating in five dimensions, the 43 entries Students' life events multidimensional assessment questionnaire. Middle School Students 'life events rated high packet detection rate and sub-health state, the detection rate of self-injury, suicide, Internet addiction and other health risk behaviors were significantly correlated, prompt MLERQ has good empirical validity as a measure of students' life the event of a valid tool.
