4. The RE-AIM framework for evaluating implementation processes and public health impact

IMPRESA employs the RE-AIM framework to assess the impact of tailored intervention packages on the prevention and harm reduction of methamphetamine use related problems among the target groups.

IMPRESA uses quantitative routine service and assessment data to evaluate the dimensions of Reach, Effectiveness and Adoption and semi-structured interviews including open questions with policy makers, providers/practitioners and the target group to gain qualitative and quantitative insights into the implementation of the interventions in 'real world' settings and their potential for sustainability over time. A mixed-methods evaluation framework matches key evaluation questions for each dimension of RE-AIM with selected indicators and measures.

The study specific RE-AIM evaluation tools and interim results are presented.

Chances and limitations of the RE-AIM framework to measure and improve the generated public health impact.
