The relationship between childhood deviance and adult devianceIntroductionThe current study is a correlation design. This design will be used to determine if there is a relationship between childhood conduct problems or deviance and adult deviance. Childhood deviance will be defined as any psychological problem, conduct problems at school, such as physical fights or angry outbursts towards teachers or peers, adult deviance will be defined as any form of criminal record and any form of psychiatric record. .Loeber, R., Green, SL, Lahey, BB (2000). Physical fighting during childhood as a risk factor for later mental health problems. Journal of the American Academy of Child and Adolescent Psychiatry. 39, 421-428. This review article discusses physical fighting in childhood as a risk factor for later mental health problems. Some studies of this behavior show that there is a strong correlation between physical fights in childhood and mental health problems in adulthood. In this study, the author attempts to answer three main questions.1. Does the prevalence of fighting between boys in a clinical sample differ by informant or by age cohort? What is the persistence of physical fighting over a period of 7 years and does it differ according to age? What proportion of boys who fight stop fighting?2. Does persistent physical fighting predict subsequent conduct problems and mental health problems, and are multiple informant ratings a better predictor than a single informant's rating of fighting.3. Does a combination of previously defined risk factors, other than fighting, better predict later mental health problems? The author's hypothesis is that persistent physical fights are a risk factor for end of article......adult abuse. In conclusion, the following evidence suggests that children with conduct disorders may be at risk for major mental health problems. Other findings also show that children with behavioral problems also have a higher incidence of crime as adults. Antisocial personality disorder in adulthood is almost always preceded by conduct disorder in childhood. In this study, the data support the researchers' hypothesis that conduct disorders in children lead to criminality and mental disorders in adulthood. Some weaknesses exist in this study, such as a biased sample by taking high-risk participants and relying on adult self-reports of child behavior. It is unclear whether childhood conduct problems are associated with adult deviance due to the sample used. The standards of this study were good because they conformed to the standards of Sweden..
