CHAPTER I Drug use prevention

These results corroborate the qualitative conclusion of a systematic review suggesting that “programs which develop individual social skills are the most effective form of school-level intervention for the prevention of early drug use” (cannabis and other drug use).129 In contrast, presenting children with fear-arousing information is ineffective in this particular age group, as is focusing only on building self-esteem or emotional education.130 It has been estimated that if adolescents aged 10 to 15 years receive a comprehensive programme, per month they drink alcohol on 12 days less and use cannabis on 7 days less than if they receive drug information only.131 Figure 22 illustrates how a comprehensive positive development programme shaped illegal drug use among participants in Hong Kong, China.132 Computer-based universal prevention programmes without any teacher involvement have also been implemented in the school setting and have yielded effects in terms of less smoking and less alcohol use among participants.133 Fully automated software leads students through a series of sessions in which they identify social influences and are animated to correct their false perceptions of social norms. Internet-based programmes of this kind may work outside the school context as well, but reaching the target group may be a challenge. In a study in the United Kingdom, middle-school students with an elevated risk level due to certain personality factors benefited from personal and social skills training tailored to the specific developmental challenges caused by their behavioural tendencies.134 Figure 23 shows how substance use developed for ninth graders with elevated scores in anxiety sensitivity, hopelessness, impulsivity and sensation seeking and therefore with elevated risk for drug use, 128 Spoth, Greenberg and Turrisi, “Preventive interventions addressing underage drinking” (see footnote 109). 129 Faggiano and others, “School-based prevention for illicit drugs use: a systematic review” (see footnote 124). 130 Ibid. 131 M.

interactive methods, had more sessions, were of longer duration and were mediated by persons other than teachers. The life-skills approach also serves as an effective drug prevention tool for older adolescents with higher vulnerability for substance use, such as students who are considered at-risk of not graduating at the normal pace.128

depending on whether they were offered a tailored intervention or not. The two-session programme included goalsetting exercises, education about coping strategies typical for those personality traits and healthy alternatives, behavioural management and changing dysfunctional beliefs that often accompany such traits. Although alcohol and drug use were only a minor focus of the intervention, problem drinking was less probable among participants after the intervention. Apart from implementing individual-oriented interventions, preventive effects can also be achieved by targeting the general climate and drug-specific rules of schools. Feeling left out motivates people to act against conventional norms. As a major socializing agent, the school system has the potential to integrate marginalized students and facilitate positive development. With children at risk, schoolbonding activities to improve school attendance and attachment to school, in addition to promoting learning of age-appropriate language and numeracy skills, may have a positive influence in terms of developing important protective factors for students in middle childhood.135,136 Overall, interventions that promote a positive school ethos and enhance student participation and commitment to school, conjointly with rules that strongly discourage drug 135 P.
