Cyberbullying has become widespread, and is generating growing concerns as it affects students and school climates in general. The objective of this article is to investigate the prevalence of cyberbullying among Serbian adolescents. Special emphasis was placed on gender differences regarding different forms of cyberbullying and victimization. In this study, 387 middle school students from five state schools in Belgrade were surveyed in order to obtain information about the prevalence of cyberbullying and victimization. The results show that most of the students used the Internet on a daily basis and that almost all of them possess their own mobile telephones. On average, 10% of students aged 11-to 15-years-old reported that they have cyberbullied others online, whilst 20% of them were victims of cyberbullying. The most common types of victimization reported by students were denigration and harassment, and most of the cyberbullying took the form of harassment. There were significant gender differences in cyberbullying, with male students reporting higher levels of bullying others and being victimized by cyberbullies than females. Implications for prevention and intervention are presented.

Istraživanje se bavi utvrđivanjem specifičnih dimenzija ličnosti adolescenata "internet-zavisnika", ličnosti njihovih roditelja i karakteristika porodičnog funkcionisanja s ciljem boljeg razumevanja faktora rizika za razvojovog poremećaja. Uzorak je činilo 60 adolescenata oba pola, uzrasta od 15 do 18 godina, od toga 30 iz kliničke grupe "internet-zavisnika" i 30 ispitanika kontrolne grupe iz opšte populacije, kao i 120 roditelja, odnosno po 30 parova roditelja obe grupe adolescenata. U istraživanju su primenjeni upitnici za procenu zavisnosti od interneta (Young's Internet Adiction Test-IAT), za procenu ličnosti adolescenata (Belgrade Adolescent Personality Inventory-BAPI), ličnosti roditelja (Temperament and Character Inventory-Revisited-TCI-R) i procenu porodičnog funkcionisanja (Family Adaptability and Cohesion Evaluation Scale-FACES IV). Rezultati ukazuju na to da adolescente s problemom zavisnosti od interneta karakteriše visok stepen impulsivnosti i niska istrajnost, kao i nezreli aspekti karaktera koji regulišu odgovorno, ka cilju usmereno i kooperativno ponašanje. Očeviispitanika kliničke grupe imaju značajno više skorove na dimenziji Perzistencije, a majke na dimenziji Potrage za novinama, dok oba roditelja imaju povišene skorove na Self-transcendenciji, što potencijalno ukazuje na to da su manje dostupnisvojoj deci. Sve dimenzije koje se odnose na pozitivne aspekte porodičnog funkcionisanja kliničke grupe niske su prema proceni oba roditelja, dok je negativna dimenzija porodičnog funkcionisanja Haotičnost procenjena kao visoko izražena kod oba roditelja,

The results show that the dimensions of personality can play an important role in etiopathogenesis of various disorders in adolescents.

Although the fear of crime has been the subject of intensive study carried out by criminologists and sociologists in other countries for more than four decades, domestic theoretical and empirical examination of this complex phenomenon is almost nonexistent. The main objectives of this study are determining the prevalence and possible differences in the fear of crime among the residents of major cities of the former Yugoslav republics. The analysis uses data collected as part of the regional research project “The Fear of Crime in Large Cities“. The method of interviewing in households using a specially created questionnaire is applied on a multi-stage random sample of 1977 adult respondents living in urban areas of the cities. By choosing the appropriate questionnaire items, three scales to measure affective, cognitive and behavioral dimensions of the fear of crime and a unified scale of the general construct were made for the purpose of this study. All scales have high internal consistency reliability. The results show that a significant percentage of people who exhibit a high level of the fear of crime are present in all cities, regardless of the size of the dimension tested. Higher prevalence of the fear of crime is determined by measuring the extent of affective and up to a point behavioral dimension, while the prevalence of fear of crime is slightly lower on the level of the cognitive dimension. Statistically significant differences in the level of fear of crime among residents of cities studied are identified on all scales

The sense of school belonging is defined as the extent to which students feel personally accepted, respected, included and supported by others in the school environment. Given that certain authors regard school belonging as the key factor in the adequate development of children and youth, this paper aims to summarize and present theoretical and research findings that testify to the importance of the sense of school belonging for students' positive development and prevention of behavioral problems. In addition, the basic tenets of prevention science and the positive development perspective are discussed, and the relationship between these two approaches is analyzed. The results of our review suggest that the sense of school belonging is related to a wide range of academic and developmental outcomes, such as academic achievement and motivation, school engagement, prosocial behavior, life satisfaction, self-esteem, positive identity, well-being, adaptive adjustment, etc. In other words, past research has indicated that, depending on the extent to which the sense of school belonging is developed, its effects can be interpreted within the context of risk and protective/promotion factors in students' mental health and behavioral problems. The above implies that actors in the education system must not lose sight of the importance of the sense of school belonging for students' reaching their full potential. Moreover, taking into account the striving of prevention science to identify and enhance the factors underpinning protective processes, further research is needed on the factors and mechanisms of development of the sense of school belonging.
