The problem
Intervention: No intervention is evaluated; this is an observational study examining the relationship between poly-victimization exposure and delinquency outcomes
Who it was tested with: U.S. children aged 10-17 years (6,364 participants in secondary analysis from National Survey of Children's Exposure to Violence).
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"The secondary data analysis is based on a nationally representative sample of 6,364 10 to 17-year-olds who self-reported their lifetime victimization experiences and their past-year delinquency involvement. The pooled dataset used in this dissertation is based on the aggregation of three repeated assessments collected in 3-year intervals between 2008 and 2014." The study uses nationally representative data pooled across multiple years, meeting criteria for experimental evidence tier despite cross-sectional assessment within each year.
Cross-sectional design limits causal inference; U.S. population only; systematic review found most prior studies used non-probability samples and cross-sectional designs, limiting evidence quality
