STARS (Start Taking Alcohol Risks Seriously) for Families
Public Health & Prevention: School-based
  Literature review updated June 2016.
STARS (Start Taking Alcohol Risks Seriously) for Families is a universal program in which students entering 6th grade receive an individual health consultation with a school nurse addressing up to 12 risk factors. During the spring semester parents are sent up to 10 weekly postcards, requesting parents to take a few minutes to read and talk to their child about a key fact found on the card to help the child stay away from alcohol. Postcards are tailored to address particular risk factors identified in the health consultation. In the 7th grade, students receive another nurse consultation and a series of four family take-home lessons during the spring semester.
META-ANALYSIS
CITATIONS

Meta-analysis is a statistical method to combine the results from separate studies on a program, policy, or topic in order to estimate its effect on an outcome. WSIPP systematically evaluates all credible evaluations we can locate on each topic. The outcomes measured are the types of program impacts that were measured in the research literature (for example, crime or educational attainment). Treatment N represents the total number of individuals or units in the treatment group across the included studies.

An effect size (ES) is a standard metric that summarizes the degree to which a program or policy affects a measured outcome. If the effect size is positive, the outcome increases. If the effect size is negative, the outcome decreases.

Adjusted effect sizes are used to calculate the benefits from our benefit cost model. WSIPP may adjust effect sizes based on methodological characteristics of the study. For example, we may adjust effect sizes when a study has a weak research design or when the program developer is involved in the research. The magnitude of these adjustments varies depending on the topic area.

WSIPP may also adjust the second ES measurement. Research shows the magnitude of some effect sizes decrease over time. For those effect sizes, we estimate outcome-based adjustments which we apply between the first time ES is estimated and the second time ES is estimated. We also report the unadjusted effect size to show the effect sizes before any adjustments have been made. More details about these adjustments can be found in our Technical Documentation.
