This study examines the association between self-reported delinquent behaviour and psychosomatic symptoms in a nationally representative sample of 15-16-year old Finnish adolescents. Some theorists have suggested that psychosomatic symptoms are related to inability to break culturally given norms. If this is so, delinquents should have less symptoms than non-delinquents. To assess this idea, two hypotheses are formulated: delinquency is associated with decreased symptoms (the 'hydraulic' hypothesis), or delinquency is associated with increased symptoms (the 'stress' hypothesis). In support of the second hypothesis, the results indicate that delinquency and psychosomatic symptoms are positively associated. The effect of delinquency on symptoms is robust in the presence of a number of control variables. The findings are discussed i.a. from the point of view of increasing research interest in the positive effects of delinquency. While positive effects are likely to exist in specific contexts, delinquency as such does not lead to a reduction of psychosomatic symptoms.  相似文献

未成年人刑事案件社会调查制度论纲   总被引:9,自引:0,他引:9  
未成年人一般具有极强可塑性。如果法官的判决是有利于其改过自新的,则此种基于刑罚个别化的判决对该未成年人而言,无疑是再社会化和预防犯罪的良方。蕴涵人格调查的社会调查制度应当是形成前述判决的基础。在我国少年司法制度尚不完备的当下,应以该制度的正当性为基点展开研究,以期运用于少年刑事司法实践。  相似文献

Violent juvenile crime is disproportionately concentrated in urban neighborhoods, and accordingly an understanding of the sources of serious delinquency is con founded by components of urbanism. These milieus usually have high rates of absolute poverty and relative economic deprivation, as well as weak social institutions. The persistent findings of delinquent peer contributions to delinquency have yet to be tested under conditions where social class and milieu effects are controlled. There is little empirical evidence to determine how adolescents in high-crime neighborhoods avoid delinquency despite frequent contact with delinquent peers. The differences between violent delinquents and other youths from comparable neighborhoods are little understood. This study contrasts a sample of chronically violent male juvenile offenders with the general male adolescent population (students and school dropouts) from inner-city neighborhoods in four cities. Violent delinquents differ from other male adolescents in inner cities in their attachments to school, their perceptions of school safety, their associations with officially delinquent peers, their perceptions of weak maternal authority, and the extent to which they have been victims of crime. Peer delinquency and drug“problems” predict the prevalence of three delinquency offense types for both violent offenders and neighborhood youths. Among violent delinquents, there appear to be different explanatory patterns, with one type better described by internal controls (locus of control), a developmental measure. Overall, there is strong support for integrated theory including control and learning components, and similar associations exist among inner-city youths as in the general adolescent male population. Despite the generally elevated rates of delinquency in inner cities, the explanations of serious and violent delinquency appear the same when subjects are sampled at the extremes of the distribution of behavior.  相似文献

Abstract Studies of delinquent careers have often tracked only male offenders, and have almost always failed to explore the interaction of race and gender in delinquency. This study tracks a cohort of youth whose first referral to juvenile court was in 1980, and explores the role played by both race and gender in official delinquent careers. Findings reveal that both race and gender play a significant role in official delinquency. Looking first at female delinquency, this research finds that white and nonwhite females do not differ significantly in the types of offenses they commit. Moreover, if girls are “chronic” delinquents, their offenses are most often trivial rather than serious. With males, racial differences emerge in both seriousness and chronic nature of delinquency. Nonwhite males in this cohort are more likely to be referred for personal offenses and less likely to be referred for public order and victimless offenses. Nonwhite males are also significantly more likely to become recidivists, and to have more seriously delinquent careers. This article discusses the implications of these findings, particularly with reference to the “convergence theory” of delinquency, which suggests that race plays a stronger role than gender in female delinquency. Finally, the article considers the policy implications of the current range of definitions of “chronic” delinquency.  相似文献

The Pittsburgh Youth Study is a prospective longitudinal survey of three samples of Pittsburgh boys (each containing about 500 boys) initially studied in first, fourth, and seventh grades. The first two data collection waves yielded self-reported delinquency and combined delinquency seriousness scores (the combined scores based on information from boy, mother, and teacher) for the middle sample (up to an average age of 10.7 years) and oldest sample (up to an average age of 13.9 years). These scores were compared with records of petitions to the Allegheny County Juvenile Court for delinquency offenses before and up to six years after the assessments. The area under the ROC curve was used as a measure of validity. Concurrent validity was higher than predictive validity. The combined scale had similar concurrent validity but greater predictive validity than the self-report scale, and the combined scale also identified a greater number of boys as serious delinquents. Concurrent validity for admitting offenses was higher for Caucasians, but concurrent validity for admitting arrests was higher for African-Americans. There were no consistent ethnic differences in predictive validity. There was an increase in predictive validity, for both African-Americans and Caucasians, by combining self-report data with information from other sources. Afrer controlling for delinquency measures, African-Americans were more likely than Caucasians to be petitioned in the future, but not in the past. In this research, ethnic differences in official delinquency were partly attributable to ethnic differences in delinquent behavior and were not attributable to differential ethnic attrition or differential ethnic validity of measures of delinquent behavior.  相似文献

The authors explored attitudinal differences among adolescent male sex offenders, juvenile delinquents, and nondelinquent youth based on three variables drawn from integrated delinquency theory: conventional attitudes, normlessness, and social isolation. Consistent with previous juvenile delinquency studies, the results indicate no differences among the three groups on conventional attitudes. With respect to normlessness, both the sex offenders and juvenile delinquent groups demonstrated more school normlessness than did nondelinquent youths, and adolescent sex offenders showed greater peer normlessness than did either nondelinquent youths or juvenile delinquents. Examination of perceived social isolation among the three groups indicates that sex offenders consistently perceived themselves as more isolated than other youths with their families, in their school, and among their peers. These results suggest that interpersonal factors, in addition to a lack of social controls and normlessness, are associated with sexually inappropriate behavior.  相似文献

Executive functions are still developing during adolescence. It is important to analyse if juvenile delinquency is related to a delay in the development of these functions. The objective of this study was to analyse cognitive inhibition and flexibility, two components of executive functions, in juvenile delinquents. Participants were 81 males, 17.46 ± 1.60 years old. Three groups were compared: a juvenile delinquent inmate group (IG), an age-paired group (APG), and an age- and education-paired group (AEPG). A modified Stroop task was used to assess cognitive inhibition and flexibility. The IG and the AEPG (low-education adolescents) had significantly more difficulties than the APG on inhibition; the IG and the AEPG had no significant differences. No group differences were found on flexibility. Since all low-education adolescents have difficulties on inhibition, these difficulties are not an exclusive characteristic of juvenile delinquents. Analysis of cognitive processes in juvenile delinquents must control for education to determine how specific are the difficulties found in these adolescents.  相似文献

Why is juvenile delinquency associated with depression in young adulthood? One possibility is that delinquency interferes with socioeco‐nomic attainment and disrupts entry into adult roles, perhaps because of official labeling processes or adolescent socialization into deviance, and these repercussions of delinquency lead to depression. Another possibility is that grown delinquents may show high levels of depression because they tend to offend in adulthood, and adult offenders tend to be depressed. I use data from the National Longitudinal Study of Adolescent Health to examine the timing and mechanisms of the offending‐depression relationship. The results suggest that delinquency is negatively associated with later status attainment and that the status attainment deficits of grown delinquents are not fully explained by justice system contacts or by adolescent delinquent peer influence. A portion of the longitudinal delinquency‐depression link is explained by the low levels of education of grown delinquents and by their involvement with the justice system. Still, young adult depression is more closely tied to recent offending than it is to juvenile delinquency, official labeling, or the status attainment consequences of delinquency.  相似文献

This article reports the first longitudinal evidence that prospective measures of neuropsychological status predict antisocial outcomes. We studied data for a birth cohort of several hundred New Zealand males from age 13 to age 18. Age-13 neuropsychological scores predicted later delinquency measured via multiple sources: police, courts, and self-report. Poor neuropsychological scores were associated with early onset of delinquency. The results fit our predictions about two trajectories of delinquent involvement: (1) Poor neuropsychological status predicted specifically male offending that began before age 13 and persisted at high levels thereafter. (2) By contrast, in this sample neuropsychological status was unrelated to delinquency that began in adolescence.  相似文献

We attempt to isolate the effects of alcohol on different types of delinquent behavior by identifying the spurious portion of the relationship. Using data on adolescents from Finland, we compare the relationship between drinking and delinquent behavior while sober to the total relationship between drinking and delinquent behavior (sober or not). For each type of offense, we find a substantial relationship between drinking and sober delinquency, which suggests a good deal of spuriousness. For crimes of petty theft (shoplifting and stealing from home), the relationship between drinking and sober delinquency is just as strong as the total relationship, which suggests the relationship is almost completely spurious. For violence, vandalism, car theft, and graffiti writing, the alcohol‐sober delinquency relationship is weaker, which suggests that alcohol has a causal effect on these offenses.  相似文献
