In the following paper I have my goal to review the article by Robert Crosnoe, Kristan Glasgow Ericson and Sanford Dornbusch about the factors reducing and moderating the impact of deviating friendships among the adolescent boys and girls. I will also offer my comments about some of the study findings and their bias and prejudice. To study the connection between adolescent friendships and deviating conduct the researchers explored the data collected in high schools in California and Wisconsin: approximately 80% of students participated. To collect independent data the research was held in schools of different social levels from economically disadvantaged and middle class to urban and rural ones. In general 3,046 respondents provided the materials for research. The research was held during four years and the results of each year were compared altogether. The study had two primary advantages supporting their reliability: the few years’ continuation and thus the opportunity to compare the results collected during this significant period of time and the use of friends’ reported deviant influence. “The source of risk examined in the study is the deviant friendship group” (3). The factors decreasing and moderating deviating behaviors which were examined in the article are family ones (parental monitoring, parental involvement, household organization) and school ones (academic achievements, school orientation and teacher bonding). The adolescences provided their answers about to deviating behaviors from their point of view. This may definitely mean a measure of bias however it is important that such data help to have an understanding of the way adolescences evaluate themselves. In addition many specialists explain that self-report is one of the most effective ways to analyze adolescences behaviors. Risk and Protective Factors for Adolescent Deviance The study found out that adolescent girls are less deviant than boys as to their friendships and their being affected by their friends. The impact of friendships is weaker among girls, among those adolescences who are more in touch with family and school institutions and those who are less involved in different activities with their friends. Protective factors of family environment are rather significant in moderating deviation among adolescences. That way parental monitoring may protect from deviating behaviors by encouraging self-restraint, reducing opportunities to participate in deviating activities and establishing the necessity to be responsible for one’s activities before parents. Parental involvement helps their children to put goals and find their due place in the society. Strong relationships between adolescences and their parents help them to be less affected with the negative tendencies of deviating behaviors of their coevals. Household organization plays its vital role in transmitting the family values and moral standards which help adolescences to stay away from deviating behaviors. Similar to parents’ involvement teacher bonding is very important for helping adolescences to resist deviating behaviors of their peers. Teacher bonding develops due determination to resist the peer pressure and also motivates adolescences to be guided by adult standards of conduct. Lower levels of deviance are also admitted to be connected to
