This article aimed to measure the level of aggressive and delinquent behavior, identify the most common delinquent behaviors, and examine the associations of aggressive and delinquent behavior. This research involved two groups of adolescents: youth offenders from correctional facilities for minors constituting the research group (52 girls and 81 boys) and high school students constituting the control group (66 girls and 67 boys). In total, 266 people were assessed. The respondents' age at the time of the research was in the range of 16–18 years (M age = 17.22). The research was quantitative. Three diagnostic tools were used to examine the variables: a poll questionnaire developed for the purpose of this research, Self-Report Delinquency and Drug Use Measures, and the Buss–Perry Aggression Questionnaire Scale. The gathered and analyzed data provided grounds to assume that the study groups indeed differ from each other in terms of frequency of illegal and antisocial behaviors and forms of presented aggressiveness. The findings also showed significant associations between delinquent behavior levels with aggressiveness in both researched groups of adolescents. Based on the analysis of the stepwise regression approach, it was established that the factor strongly anticipating illegal and antisocial behaviors among adolescents from Correctional Facilities for Minors and High Schools is aggressiveness demonstrated in the form of physical aggression.

青年人的攻击性和犯罪行为：波兰的一项实证研究

本文旨在衡量攻击行为和违法行为的水平，确定最常见的犯罪行为，并研究攻击行为与违法行为的关联。这项研究涉及两组青少年：构成研究组的未成年人惩教机构的青少年犯罪者（52名女孩和81名男孩）和构成对照组的高中学生（66名女孩和67名男孩）。总共评估了266人。在调查时，受访者的年龄在16-18岁之间（M年龄= 17.22）。这项研究是定量的。使用了三种诊断工具来检查变量：为该研究目的而开发的民意调查问卷，自我报告的过失和药物使用措施以及巴斯-佩里侵略问卷调查量表。收集和分析的数据提供了依据，可以假设研究组在非法和反社会行为的频率以及表现出的侵略性方面确实彼此不同。研究结果还显示，在两个研究的青少年组中，犯罪行为水平与攻击性之间存在显着关联。根据逐步回归方法的分析，
