TL;DR: A review of the most important results in criminology have been obtained in longitudinal or experimental studies, and the major studies of these types are reviewed here as mentioned in this paper, and it is now desirable to combine the two methods in a new coordinated program of longitudinal studies including experimental interventions or quasi-experimental analyses.

TL;DR: Many of the best predictors of juvenile offending are well known. as mentioned in this paper reviewed numerous research projects showing the predictive power of: early troublesome, dishonest, aggressive, or antisocial behavior; poor parental child-rearing methods, such as cruel, passive, or neglecting attitudes, harsh or erratic discipline, and poor supervision.

TL;DR: In this article, the authors present a brief review of the situation in: Australia, Canada, Germany, Netherlands, Spain, the United Kingdom, and the United States, and find that while all seven countries are moving towards evidence-based decision making regarding policies and programs to prevent violence, there remain a number of difficulties before this end can be achieved.

TL;DR: In this article, a systematic search for studies that included a measure of offending, compared self-reported data on offending between different methods, and used an experimental design was carried out, and the effect sizes were used to summarize the results.
