  1. Effectiveness of substance abuse prevention Dr. Anneke Bühler IFT Institut für Therapieforschung, München, Germany Pompidou Group Conference „Families, lifestyles and drugs – reaching families in prevention“, Porto, Portugal 19-20 November 2007 Anneke Bühler, IFT München: Expertise Suchtprävention

  2. Report on prevention of substance abuse (Bühler & Kröger, 2006)* • Aim: up-to-date record of research results on substance abuse prevention • Method: Systematic search and analysis of 49 high-quality reviews and meta-analyses • Results: Evidence-based conclusions about effectiveness of preventive measures (avoidance, delay, or reduction of substance use behaviour) • status quo, mean , mainly US research *in cooperation and with financial support of the BZgA Anneke Bühler, IFT München: Expertise Suchtprävention

  3. Strength of evidence rating Conclusion is based on... °°°°° meta-analyses including high-quality studies (M) °°°° systematic review including high-quality studies (S) °°° meta-analyses or systematic review including all types of studies °° unsystematic review (U), expert interview (E) or best practice survey(BP) ° generalized empirical result which does not directly inform about or test the assumption - contradictory body of evidence Anneke Bühler, IFT München: Expertise Suchtprävention

  4. Family • Comprehensive family-oriented approaches (training with parents, children and whole families) have preventive effects on consumption behaviour (in relation to alcohol). °°° • Measures to involve hard-to-reach families are successful. °° • Preventive measures for pre-school children (aged 3-5 years) should be family orientated. ° Anneke Bühler, IFT München: Expertise Suchtprävention

  5. School • Interactive school-based programmes have preventive effects on consumption behaviour (for tobacco, alcohol, cannabis and other illegal drugs). °°°°° • Social influence model and life skills approach • Non-interactive programmes are not effective: Information giving alone, affective education alone, value clarification and decision-making alone. °°°°° Anneke Bühler, IFT München: Expertise Suchtprävention

  6. Peers/Leisure time • No aggregated information available in report • For selective approach • Springer et al., 2004 : National Cross-Site Evaluation of High-Risk Youth Programs with 48 programs with over 10.500 youths at high risk • Behavioral life skills and recreation focused programs are effective.(°°°°°) Anneke Bühler, IFT München: Expertise Suchtprävention

  7. Media campaigns • Mass-media campaigns in combination with other components (school-based, community-based and national programmes) have preventive effects on consumption behaviour (in relation to tobacco). °°° • Isolated mass-media campaigns have no preventive effects on consumption (of tobacco). °°°° Anneke Bühler, IFT München: Expertise Suchtprävention

  8. Community Collaboration • Capacity building • Integrating services • Influencing policy • Collaborative initiatives aimed at getting policies or regulations introduced are effective because of the effectiveness of policy measures.°° Anneke Bühler, IFT München: Expertise Suchtprävention

  9. Community Multi-level approach • Measures in different settings (school, media, family, community) • Inconclusive: Multi-level projects have preventive effects on consumption behaviour. (pro: °°°°°; inconclusive: °°°°) Anneke Bühler, IFT München: Expertise Suchtprävention

  10. Policy and regulations • Higher tobacco prices reduce the prevalence and quantity of tobacco consumption. °°° • Isolated measures to prevent the sale of tobacco to young people under the legal age do not reduce consumption. °°° Anneke Bühler, IFT München: Expertise Suchtprävention

  11. Policy and regulations • Raising the minimum legal drinking age reduces alcohol consumption. °°°° • Higher ´full‘ alcohol prices (including indirect costs) have effects on alcohol consumption.°° Anneke Bühler, IFT München: Expertise Suchtprävention

  12. Selective prevention • Selective prevention measures have preventive effects on consumption behaviour if they are implemented in the form of • school-based social-skills programmes or • mentoring programmes.°°°°° • Behavioral life skills and recreation focused programs are effective.(°°°°°) • Characteristics of effectiveness: • Life skills development content • Intense contact (>3h per week) • Connection-Building methods • Instrospection methods • Coherence of program theory Anneke Bühler, IFT München: Expertise Suchtprävention

  13. What can be learnt so far... • Personal and environmental measures can be effective. • Certain measures are ineffective. • Effective measures • are based on a coherent program theory • include general and specific content • use interactive measures • have a certain intensity Anneke Bühler, IFT München: Expertise Suchtprävention
