TL;DR: In this article, a self-report questionnaire on bullying and delinquency was completed by 113 girls and 125 boys aged 11-14 in a middle school in Rome, and the authors aimed to analyse the personal characteristics and parental styles of bullies and delinquents, and to establish which factors were related to the bully/delinquent group and which were related with only bullies or only delinquents.

TL;DR: This paper presented a systematic review and meta-analysis of the effectiveness of programs designed to reduce school bullying perpetration and victimization (i.e. being bullied) and explained the pitfalls of previous reviews and explain in detail how the present systematic review This paper addressed the gaps in the existing literature on bullying prevention.

TL;DR: The number of children experiencing parental imprisonment is increasing in Western industrialized countries as mentioned in this paper, which is a risk factor for child antisocial behavior, offending, mental health problems, drug abuse, school failure, and unemployment.

Abstract: Perhaps the most frequently documented conclusion about delinquent behavior is that most offenses are committed with others rather than by persons acting alone Breckenridge and Abbott' were perhaps the first to observe that not only are most delinquent offenses committed with others, but that even most youths who routinely offend alone are influenced by others Because of this article's behavioral perspective, we refer to persons who act together in a crime as co-offenders and to their committing that crime as cooffending2 Co-offending is a universal pattern in all major forms of delinquency and characterizes offending patterns in countries with widely different cultural traditions such as Argentina,3 Japan,4 and India5

TL;DR: In this article, the authors identify the key risk factors for offending (in longitudinal studies) and implement prevention methods designed to counteract them (in experiments) in order to identify and enhance the protective factors.
