ObjectiveTo investigate the demand for drug education for adolescents,to explore the liability to illicitdrugs abuse among adolescents and the risk factors,and to develop a prevention model againstillicit drug abuse among junior high schools,to evaluate the effects by implemented on a largescale.Methods1.Requirement investigationThe subjects include 592 junior students,175 parents and 67 teachers which were on thevirtue education,health education and supervisors of the classes that the students came from forrequirement questionnaire investigation from an urban school and a rural school in Xiangfan cityand Daye city respectively by means of stratified-clustered sampling.The questionnaire wasJunior High School Illicit Drugs and AIDS Prevention Requirement Questionnaire,consisting ofstudents',teachers' and parents' sub-questionnaire.It probes the requirement of adolescent illicitdrugs and AIDS prevention requirement,such as form and content.The focus group discussionwas adopted,and interviews were recorded and analyzed.2.Risk factor analysisMultistage sampling was used.Firstly,two municipal bureaus were invited to participate inthis study from each of the five regions in China,namely,East Region,South Region,West Region,North Region and Centre Region.The first seven responding bureaus were chosen,of which twobureaus also took part in the teachers' training for adolescent illicit drug prevention.At last,149teachers finished the questionnaire Adolescent Illicit Drug Abuse Prevention Education Teachers' Training Assessment.Seven schools were selected by the bureaus,and there were 28 classes,14invention groups and 14 controls.There were 1643 junior students who finished the first baselinequestionnaire.After the intervention groups completed the adolescent illicit drug prevention educationprogram,1550 students finished the second questionnaire investigation.The questionnaire wasAdolescent Illicit Drug Abuse Cognitions,Attitude and liability,and it was completed by studentsanonymously after their informed consent.The analysis of risk factors against liability to illicitdrugs use was based on the first investigation while the effects of CMER program were measuredon the basis of the two questionnaire investigations.3.Statstical methodsPoisson regression analysis,structural equation model and back-propagation neural networkwere used to explore the risk factors against liability to illicit drugs use among adolescents.Hypothesis tests were analyzed with independent t-test or t'-test,chi-square test or Fisher's exacttest at the 0.05 level,two-tailed.Results1.Results of requirement investigationThere were respectively 23.48% and 20.95% of the junior students who had not received anydrugs related education at all,and the proportion was even larger in rural schools.Only 8.61%and 9.80% of the students did think they know how to keep away from drugs/AIDS.Over 86% ofstudents,teachers and parents agreed to participate in the school-based education of preventionknowledge.The major acceptable forms were lessons by teachers,watching video,listening toaddicts' experience and discussion.The definitions of drugs and new drugs,AIDS,harm of drugsand skills of refusing drugs were considered to be important contents by junior students andteachers.2.Results of risk factor analysisThe results of multiple Poisson regression analysis indicated that wrong attitude,refusal skillsdeficiency and low emotion quotient (EQ) were risk factors of liability to adolescent illicit drugs abuse.The results of structural equation model showed that illicit drug knowledge (F1),attitude(F2),refusal skills (F3) and EQ (F4) affected liability to illicit drugs use (F5) directly,while F1affected F5 through F2 and F3 indirectly.The goodness indexes of structural equation model werefollowed as GFI=0.941,AGFI=0.922,CFI=0.899,NFI = 0.882,PGFI = 0.793,RMSEA=0.058,90%CI.RMSEA=0.054~0.062,CN=300.The accuracy of BP neutral net model was morethan 80%.3.Results of effects on the interventionAfter the first investigation,the score of knowledge and skills except addiction increased inthe control,while the scores of attitude to illicit drugs use decreased,and the curiosity towardillicit drugs grew.After intervention,the score of knowledge,attitude,refusal skills and EQ havebeen improved in the intervention group.At the first investigation,the scores of knowledge,attitude,refusal skills and EQ were no better than the intervention group.After the intervention,the score of knowledge,attitude,refusal skills and EQ were higher than the control,and fewerstudents showed curiosity to illicit drugs.Conclusion1.Junior high school students,teachers and parents all thought that it is necessary to organizethe illicit drugs abuse prevention education school-based.And they thought illicit drug,new typedrugs,their harm and how to refuse temptation as the education contents.Students were glad tohave the education from the styles,such as listening from teachers,watching meaningful videos,listening to the addicts' stories and discussion.It is very necessary to develop a systemic illicitdrug abuse prevention education based on requirement.2.Illicit drug knowledge,attitude,refusal skills and EQ were risk factors of liability to illicitdrugs abuse,which verified the necessity of cognition-motivation-emotion and refusal skills(CMER) prevention program.3.Based on the large scale CMER intervention,CMER program can enforce the knowledge,reduce the motivation to illicit drugs use,improve the refusal skills and EQ,and reduce theliability to illicit drugs abuse. Innovation1.In China,it was the first time to investigate and explore the requirement for content andstyle and cooperationextent.2.We explored the statistic methods on illicit drug abuse and evaluation of interventionsystematically.Based on data,the Poisson model,structural equation model and BP neural netmodel were established.It was found that Poisson regression model can help to find risk factors toillicit drugs abuse among junior high school students.Combination structural equation model withBP neural net model to explore the relation among risk factors,the effects of prediction the liabilityto illicit drugs abuse among junior high school were good.3.By means of training teachers on health education among adolescents,we found that theteachers agreed with the CMER model and the related books.The sustainability and practicabilityof the adolescent illicit drugs abuse CMER prevention were guaranteed.4.It is the first time that adolescent illicit drugs abuse CMER prevention was popularized toseven cities in China,covering Eastern,Southern,Western,Northern and Central areas.It had beentested the practicability and acceptability.
