Secondary Prevention Interventions for Young Drug Users: A Systematic Review of the Evidence

Article excerpt


Drugs are commonly used by young people (Weinberg, Rahdert, Colliver, & Glantz, 1998; Bauman & Philayrath, 1999). With the exception of alcohol and tobacco, the most commonly used drug internationally is cannabis (Kingery, Alford, & Coggeshal], 1999). Lifetime prevalence of cannabis use is reported by at least one third of older adolescents in the United Kingdom (UK), New Zealand, and Switzerland (Bauman & Philayrath, 1999). Use of other drugs such as cocaine, stimulants, and inhalants are less common (Bauman & Philayrath, 1999; Kingery et al., 1999). There are important subgroups exposed to risks of drug use or problems associated with drug use. Between 0.4% and 3.3% of young drug users meet the criteria for abuse or dependence (Weinberg et al., 1998). It is likely that these groups of young people experience multiple problems (Lloyd, 1998). Coexisting problems include poor general health, poor family and social relations, dropping out of school, and psychiatric and psychological disorders such as depression and behavior problems (Weinberg et al., 1998; Swadi, 1999; Bray, Zarkin, Ringwalt, & Qi, 2000; Reid, Lynskey, & Copeland, 2000; Ferguson, Horwood, & Swain-Campbell, 2002).

A comprehensive range of services may be required to address the problems experienced by some young drug users (Crome, 1999; Gilvarry, 2000). These services might include a comprehensive needs assessment, family therapy, pharmacotherapy, outreach work, and residential care (Sloboda, 1999; Gilvarry, 2000). Other commentators discuss the possibility of embedding drugs services within existing health and social care agencies (Lloyd, 1998). These interventions are often advocated on the basis of expert opinion or selective review of the scientific literature. The extent to which these views are fully supported by the scientific literature is unclear.

The UK government's ten-year drug strategy published in 1998, and subsequently the Scottish Executive strategy published in 1999, set out to prevent drug use and improve access to drugs services for young people, including those up to the age of 16 years (Great Britain Cabinet Office, 1998; Scottish Office, 1999). The Effective Interventions Unit, Scottish Executive, commissioned the authors to undertake a review of the scientific evidence concerning the effectiveness of drugs interventions for young people, particularly those 16 years of age and under. The review would help inform the key principles and core models for service provision for young people. A final report was expected within a six-month period. The reason for the short time period was to fit the policy-making schedule.

It is against this background that the present review was conducted. The aim is to identify, critically appraise, and synthesize the international scientific evidence on the effectiveness of secondary prevention interventions for young drug users. The key questions are, How effective are secondary prevention interventions in: (1) reducing drug use among young users? (2) improving the psychological well-being of young drug users? and (3) improving the family and social relations of young drug users? The review also comments on the coverage of the current research and makes recommendations for service provision and research.
