The disposables: our treatment of violent adolescents

This paper discusses the clinical perceptions of levels of attachment disorder as theorized by John Bowlby. The findings are based on interview data of juvenile delinquent offenders who have committed criminal acts that are serious enough to warrant their being tried as adults. The data are based on clinical interviews, and the interviewer encourages empirical research of the clinical findings. It is suggested that attachment levels may be a viable means of determining appropriate types of rehabilitative interventions for juvenile offenders.     

The moderating role of empathy in the association between parental support and adolescent aggressive and delinquent behavior

The present two‐wave longitudinal study addressed the role of affective empathy and parental support in aggressive and delinquent behavior in a sample of 323 adolescents (158 boys, 165 girls). Self‐report questionnaires were used to assess affective empathy, perceived support from parents, delinquency, and aggression. Guided by theories on children's differential susceptibility to socialization, we expected adolescents with different levels of empathy to vary in their responsiveness to parental support. In agreement with our hypothesis, empathy moderated the relation of perceived parental support with aggressive and delinquent behavior. Controlling for the effect of gender and for the stability of aggression and delinquency, higher perceived parental support was predictive of lower levels of aggression at age 15, but only for adolescents high in empathy. Remarkably, adolescents low in empathy not only appeared to benefit less from parental support, but even showed more aggression and delinquency at age 15 when they perceived their parents to be more supportive at age 14.

Correlates of aggressive and delinquent conduct problems in adolescence

The primary purpose of the study was to test a hypothetical model for aggressive and delinquent conduct problems in adolescence. A total of 168 adolescents from 121 families were studied using several questionnaires and a semi‐structured interview. The following factors were considered: obstetric complications, temperament (novelty‐seeking), self‐esteem, family influences (perceived parenting, alcohol abuse/dependence of parents, antisocial personality disorder of the father) and peer‐group characteristics (peer rejection and membership in a deviant peer group). The evaluation methods applied included correlation analyses and testing of two hypothetical models using structural equation modeling. The correlation analyses revealed significant relationships between adolescent aggressive and delinquent behavioral problems and parental antisocial behavior; perceived parental rejection and low emotional warmth; adolescent novelty‐seeking, self‐esteem, peer rejection and peer deviance. The two empirical models, separately for aggressive and delinquent behavior problems, revealed direct relationships between paternal antisocial behavior, parental rejection, adolescent novelty seeking, peer deviance, peer rejection, and offspring aggression and delinquency. There were, however, two differences with respect to the relationships between peer rejection, peer deviance, aggression and delinquency. First, peer rejection was more strongly associated with aggressive behavior and only moderately linked to delinquency. Second, deviance in the peer‐group was found to be closely related with delinquency but only moderately with aggression. Our findings suggest that several pathways for aggressive and delinquent conduct problems are comparable while others were not. Regarding the findings of the empirical models, we conclude that only intervention measures that include parents, peers and individual adolescents may help decrease the incidence of aggressive and delinquent conduct problems.

Intellectual, behavioral, and personality correlates of violent vs. non-violent juvenile offenders

The overall aim of this study was to examine the relationship between offender status (violent vs. nonviolent) and selected predictor variables from personality, behavioral, and intellectual domains. The two main sub goals were (a) to determine which variables from these domains were most closely associated with offender status, and (b) to construct a stepwise logistic regression model that could help identify which juveniles were more likely to be incarcerated for violent vs. nonviolent offenses. The participants for this investigation were juvenile offenders referred to the Juvenile Court Assessment Center by the Juvenile Justice Division of the Eleventh Judicial Circuit. The court-ordered assessment included the following measures: (a) The Millon Adolescent Clinical Inventory (MACI), (b) the Behavior Assessment System for Children (BASC), (c) the Peabody Picture Vocabulary Test-Third Edition (PPVT-III), (d) the Wide Range Achievement Test-Third Edition (WRAT-III), (e) the Kaufman Brief Intelligence Test (K-BIT), and (f) records of school achievement. The ten variables that had the strongest association with offender status were entered into the stepwise logistic regression analysis; five of these strategically chosen predictor variables accurately differentiated violent from nonviolent offenders 86.3% of the time. Reading Percentile (β=-.051), PPVT-III (β=-.059), MACI-Inhibition (β=-.033), MACI-Eating Dysfunction (β=.051), and BASC-Sense of Inadequacy (β=-.072). Gender differences were explored.     

Substance use patterns of young offenders and violent crime

The use of alcohol is a significant predictor of the involvement of young offenders in violent crime. This study found that in a sample of 300 incarcerated juveniles in New South Wales, more than 70% admitted to violent crime. Detainees from an Aboriginal or Torres Strait Islander culture were less likely than other detainees to be involved in violent crime. The substances most associated with violent crime were alcohol, followed by cocaine. However, when the likelihood that the young person has initiated violence as a response to alcohol or other substances is introduced into the equation, the direct effects for alcohol and cocaine predicting engagement in violent crime disappear. The Goldstein hypothesis that the effects of a substance directly facilitate violence, thereby accounting for the relationship between substances of use and violent crime, was supported. Aggr.

The Relationship of Trauma to Nonsexual Crimes Committed by Adolescent Sexual Abusers: A New Area of Research

In an early investigation on the topic of the relationship between trauma history and nonsexual crimes committed by sexual offenders, this study examined nonsexual crimes committed by a sample of 451 juvenile sexual abusers. More than 60% of this sample committed quite serious crimes (i.e., animal cruelty, arson, assault, burglary, car theft, drug-related crimes, or theft). Based on the delinquency literature, childhood victimization significantly predicted severity of criminal behavior for this sample. Implications for research and practice are discussed.     

Investigating a socially anxious‐impulsive subgroup of adolescents: A prospective community study

Previous research has identified a subgroup of socially anxious adults who are both anxious and impulsive. To date, however, this subgroup has not been identified in adolescence. Therefore, in this study we aimed to identify this subgroup in a sample of adolescents. In addition, we hypothesized that this subgroup would be higher on problem behaviors, and that these processes would be moderated by gender. We used longitudinal data from 714 adolescents who were in the 7th and 8th grades at Time 1. They were followed annually for three years. Cluster analyses identified an anxious‐inhibited subgroup as well as an anxious‐impulsive subgroup in early adolescence (Time 1). The socially anxious‐impulsive adolescent boys were generally higher on both intoxication frequency and delinquency compared with all other adolescents in all clusters at each time point. Findings suggest that social anxiety subgroups may differ on problem behavior, and that early detection of an anxious‐impulsive subgroup may be important to prevent maladjustment, especially for adolescent boys.     

药物成瘾者决策缺陷的特征、机制及干预

药物成瘾者存在决策缺陷, 并表现出冲动性、风险寻求、奖赏失调、躯体内感信号缺失等特征。神经影像学研究表明药物滥用导致成瘾者背外侧前额皮层、前扣带回、眶额叶皮层、腹内侧前额皮层、杏仁核、脑岛等脑区受损, 这些损伤是引发其决策缺陷的主要原因。认知训练有利于提高个体的决策能力, 如目标管理训练和正念冥想等可以增强个体工作记忆、促进自我觉察和以目标为导向的行为; 而非侵入性脑刺激则可以直接改变与成瘾者决策相关脑区的激活状态, 从而提升与决策相关的认知功能。总体而言, 未来认知训练和非侵入性脑刺激在成瘾干预方面仍有广阔的拓展空间。     

Perceptions of Juvenile Offenders Who Were Abused as Children

Should a history of child abuse be taken into consideration when a juvenile offender is punished? Although some research shows that child abuse is used as a mitigating factor for juvenile offenders (i.e., elicits less punitive sentences), surveys of juvenile court officials reveal that it is considered an aggravating factor. Specifically, in controlled mock jury studies in which child abuse is experimentally manipulated, child abuse elicits less punitive sentences. In contrast, child abuse elicits more punitive sentences in a nonexperimentally controlled environment—the juvenile justice system. This article provides a comprehensive literature review to explain these conflicting bodies of research by considering factors that naturally covary with childhood abuse: chaotic family environment, mental health problems, behavioral problems, and school problems.     

Longitudinal Study of Mild Delinquency and In-School Problem Behaviors During Junior High School1

This research investigates repetitive problem behavior (in-school problems and mild delinquency) in Japanese junior high school students from their first to third year (12–15 years old) and examines the risk factors for repetitive problem behavior among parent–child relationships, school, individual, and lifestyle factors. An analysis of the longitudinal data of 470 students (Data Set 1) found that repeated problem behavior in school was affected by low self-control, poor relationships with teachers, and lack of parental monitoring. Repeated mild delinquent behavior was affected by parental violence, poor relationships with mothers, less sleep duration, and not belonging to club activities. Some students exhibited both mild delinquency and in-school problems. Students who experienced problem behavior 10 times or more in their second year had often experienced some problem behavior (1–9 times) in their first year. Analysis of the longitudinal data of 368 students (Data Set 2) showed that in many cases, students who exhibited repeated delinquent behavior in their second year continued to exhibit problem behavior after they became third-year students. Though the number of students with repetitive mild delinquency that was totally remedied in their third year was small, a low incidence of parental violence was seen as an antecedent factor for students who did not commit mild delinquency in their third year in spite of a high frequency of delinquency in their second year.     

Adolescent Fathers Who Are Incarcerated Juvenile Offenders: Explanatory Study of the Co-Occurrence of Two Problem Behaviors

We identify explanatory risk variables associated with the co-occurrence of two problem behaviors: juvenile offending and adolescent fatherhood. Data were gathered from a 5-year prospective, longitudinal study of 531 incarcerated juvenile offenders as they transitioned from youth correction facilities back into the community. Of the total sample, 125 (28.3%) of the male participants reported fatherhood before their 20th birthday. Six risk variables were predictive of adolescent fatherhood in this sample: (a) gang member, (b) resided with non-biological parent as primary caretaker, (c) low SES, (d) child of parent with alcoholism, (e) low mother education, and (f) family member convicted of a felony. These variables were then placed in individual, family, and social domains. Cumulative probabilities identified family related variables as the primary domain contributing to the predictive multivariate model. These results provide support for the development of prevention and interventions strategies focused across multiple ecological contexts, focusing specifically on the family unit.     

Short- and long-term consequences in decision-making under risk: immediate feedback about long-term prospects benefits people tending to impulsive processing

Many decisions in everyday life involve weighing up immediate and expected future outcomes that may be conflictive. Yet, it is still unclear which cognitive functions may affect decision-making in such situations. We examined 150 healthy subjects using a new decision-making task that measures people’s ability at handling short- and long-term consequences under objective risk. Two task versions were developed to investigate the effects of feedback about long-term consequences on decision-making. One version includes feedback about changes in long-term prospects while the other does not. Both groups revealed that advantageous decision-making correlated with reasoning and working-memory abilities, however, no correlations with executive functions were found. The effect of feedback on decision-making performance was moderated by impulsivity and need for cognition. Our findings contribute to recent dual-system approaches for risky decision-making by showing that individuals with predispositions towards impulsive rather than reflective information processing could profit from feedback about long-term prospects.     

Predicting intended contraception in a sample of ethiopian female adolescents: The validity of the theory of planned behavior

Abstract

The purposes of the study were threefold. First, to test the validity of Ajzen's (1991) theory of planned behavior (TPB) in predicting intended contraception in the Ethiopian cultural setting. Second, to examine the additional predictive roles of past behavior and perceived pregnancy risk in the TPB model. Third, to identify the salient contraceptive beliefs influencing intended contraception. Data stemmed from a community sample of 354 sexually active female adolescents aged 15 to 19 years. The findings of the study supported TPB as a robust model in Ethiopian cultural setting, with subjective norm being the strongest predictor of intended contraception. In addition, both past contraceptive behavior and perceived pregnancy risk demonstrated to have significant contributions in predicting intention over and above that explained by attitude, subjective norm and perceived behavioral control elements of the TPB. Moreover, the study also identified salient and important contraceptive beliefs that need to be addressed in family life education and counseling programs designed for adolescents and the youth.     

Development of adolescence‐limited,late‐onset,and persistent offenders from age 8 to age 48

This article investigates the life success at ages 32 and 48 of four categories of males: nonoffenders, adolescence‐limited offenders (convicted only at ages 10–20), late‐onset offenders (convicted only at ages 21–50), and persistent offenders (convicted at both ages 10–20 and 21–50). In the Cambridge Study in Delinquent Development, 411 South London males have been followed up from age 8 to 48 in repeated personal interviews. There was considerable continuity in offending over time. Persistent offenders had the longest criminal careers (averaging 18.4 years), and most of them had convictions for violence. Persistent offenders were leading the most unsuccessful lives at ages 32 and 48, although all categories of males became more successful with age. By age 48, the life success of adolescence‐limited offenders was similar to that of nonoffenders. The most important risk factors at ages 8–18 that predicted which offenders would persist after age 21 were heavy drinking at age 18, hyperactivity at ages 12–14, and low popularity and harsh discipline at ages 8–10. The most important risk factors that predicted which nonoffenders would onset after age 21 were poor housing and low nonverbal IQ at ages 8–10, high neuroticism at age 16, and anti‐establishment attitudes and motoring convictions at age 18. It was suggested that nervousness and neuroticism may have protected children at risk from offending in adolescence and the teenage years. Aggr. Behav. 35:150–163, 2009. © 2009 Wiley‐Liss, Inc.     

Behavioural characteristics of adolescence in young captive european rabbits,oryctolagus cuniculus

The territoriality of young, wild-type European rabbits, Oryctolagus cuniculus was studied in the laboratory. The experimental procedure was to introduce a strange animal into the pen (“home”) of another rabbit and to record the occurrence of the following forms of behaviour: approach, sniffing, following and chasing, aggression. Altogether 290 rabbits of the following age classes were used - 16 to 30, 31 to 60, 61 to 90, and 91 to 120 days old, and adult females and males The young rabbits were members of 62 separate litters Thirty tests were carried out for each of 21 age-class combinations giving a total of 630 separate tests each lasting 10 minutes. The data collected were subjected to statistical analysis using a multivariate parametric approach to paired comparisons The multiple discriminant analysis was used. The results indicated the preparedness of even the youngest rabbits to defend their own territory and the inhibiting effect of strange territory on all rabbits, except the 61–90-day-old subjects referred to as adolescents. The adolescents displayed aggression to younger as well as older rabbits. Within their own age group even a few days seniority of the introduced individual levelled the intensity of aggression of contestants. This behavioural characteristic was not present in the oldest age class (91–120 days old). The results are discussed in relation to information on the behaviour of free-living rabbits. The innate nature of territoriality of the species is emphasised.     

Feedback on health status and peer popularity influences social risk decision-making processes in adolescents and young adults

Cognitive and dual-processes models, involving cognitive and socio-emotional components, for adolescents’ risky behaviour have been proposed. This study tested their predictions by manipulating the presence or absence of feedback about gains and losses in health and peer popularity in a decision-making task with peers. Risky (e.g., taking or refusing a drug) and ambiguous decisions (e.g., eating hamburger or hotdog) were examined in 256 adolescents (aged 13–14; 15–16; 17–18) and young adults (aged 19–20). Participants made more risky choices and required less decision time when receiving feedback about the negative consequences on health and positive consequences on peer popularity. Decision times were comparatively larger for risky than for safe options in late adolescence and young adulthood. Results supported the dual-processes model showing that, though late cognitive changes were observed that could eventually lead to the selection of safe options, feedback gains in peer popularity outweighed unhealthy consequences leading to risky decisions.
