Female adolescent friendship and delinquent behavior

Young female offenders (n = 29) and female high school students (n = 47) were compared in terms of delinquent behavior and relationships with their best female friend and peer group. Young offenders exhibited significantly more delinquent behavior than did high school students in the past year. Delinquents and nondelinquents did not significantly differ in amount of companionship, conflict, help, security, and closeness with their best female friend, and amount of trust, alienation, and perceived intimacy in their peer group. Less communication and more perceived peer pressure in the peer group distinguished delinquent females from nondelinquent females. Perceived peer pressure significantly predicted delinquent behavior in female adolescents. In short, friendships of delinquent and nondelinquent female adolescents are essentially similar despite higher levels of peer pressure among delinquents.     

Genetically influenced change in sensation seeking drives the rise of delinquent behavior during adolescence

Sensation seeking is associated with an increased propensity for delinquency, and emerging research on personality change suggests that mean levels of sensation seeking increase substantially from childhood to adolescence. The current study tested whether individual differences in the rate of change of sensation seeking predicted within-person change in delinquent behavior and whether genetically influenced differences in rate of personality change accounted for this association. Sensation seeking and delinquent behavior were assessed biennially between ages 10-11 and 16-17 in a nationally representative sample of 7675 youths from the National Longitudinal Study of Youth: Children and Young Adults (CNLSY). Analyses using latent growth curve modeling found that within-person change in sensation seeking was significantly and positively correlated with within-person change in delinquency from childhood to adolescence. Furthermore, behavioral genetic analyses of a subset of 2562 sibling pairs indicated that there were substantial genetic influences on both initial levels of sensation seeking and change in sensation seeking during early adolescence, with over 80% of individual differences in change due to genetic factors. Finally, these genetically driven increases in sensation seeking were most important for predicting increases in delinquency, whereas environmental paths between sensation seeking and delinquency were not significant. These results suggest that developmental changes in delinquent behaviors during adolescence are driven by a genetically governed process of personality change.     

Stressful life events and impulsiveness in failed suicide

The relationship of recent stressful life events with impulsiveness in triggering suicide attempts and how impulsiveness changes from one suicide attempt to another is unclear. This study used structured-interview tools and standardized measurements to examine the relationship between life stress and impulsiveness in a sample of patients who required hospitalization for a medically serious suicide attempt. After controlling for potentially confounding variables, the number of disrupted interpersonal relationships in the preceding year was a significant predictor of the impulsiveness of the suicide attempt, with three or more losses (but not other life stresses) associated with less impulsive attempts (T = 2.4, p = .02). Female gender (T = -1.98, p = .05) and lifetime DMS-III-R diagnoses (T = -2.45, p = .02) were significantly associated with more impulsive attempts. In 55 patients with at least two suicide attempts, impulsiveness, lethal intent, and communication of intent were significantly greater for the present compared to the prior attempt (p = 0.000). Certain stressful life events, gender, and total lifetime DSM-III-R diagnoses are associated with impulsiveness of failed suicide attempts; yet, impulsiveness is not necessarily consistent from one suicide attempt to another. This evidence supports and amplifies a stress-diathesis model of suicide behavior. Accordingly, efforts to increase personal resilience in individuals who have "failed suicide" may be more effective at preventing suicide morbidity than simple stress-reduction measures alone.     

Stressful life events: Their past and present status

The present paper reviews some of the major fields of interest in current life event research. Some theoretical issues are examined: for example, generality versus specificity of life event effects, the time span encompassed by life event research, development of life change scales, and perceptual concensus concerning the severity of life changes. Methodological problems concerned with causal or correlational conclusions and illness behaviour are also discussed. Models of the life event stress process are mentioned with reference to ‘resistance resources’. Finally the field of life event research has been integrated into McGrath’s conceptualization of stress research.     

Early disruptive behavior,IQ, and later school achievement and delinquent behavior

A series of structural equation models is developed to examine the relationship between early externalizing behaviors (conduct problems, attention deficit) and IQ measured at age 8 years, academic achievement over the period 10 to 13 years, and delinquent behavior to the age of 15 in a birth cohort of New Zealand children. These models indicated that early externalizing behaviors and IQ were related to later academic achievement and delinquent behavior by two quite distinct but highly correlated developmental sequences. In one sequence early conduct problems were predictive of later delinquency but were not directly related to later academic achievement. In the other sequence, attention deficit and IQ were prognostic of later school achievement but were not directly related to delinquency. Further, the apparent correlations between academic achievement and delinquency were adequately explained by the common and correlated effects of early behavior and IQ on later achievement and delinquency. These conclusions remained unchanged when the sample was stratified by gender, and when further explanatory factors were introduced into the model.This research was funded by grants from the Health Research Council of New Zealand, the Canterbury Medical Research Foundation and the National Child Health Research Foundation.     

Conflicts between parents and aggressive and delinquent behavior in children

The exposure of children to their parents' conflicts are a factor of substantial risk for the development of behavior problems in children. This study examines the relationship between marital conflicts and children's aggressive and delinquent behavior. The sample consisted of a total of 332 children, aged 7 to 17 years, and their mothers. The children completed the Children's Perceptions of Interparental Conflict Scale, providing information on the dimensions of the marital conflicts: frequency, intensity, no resolution, and content. The mothers completed the O'Leary Porter Scale, providing information about the frequency of conflicts, and the Child Behavior Checklist, about the aggressive and delinquent behavior problems in their children. The results indicate that parental conflicts affect sons and daughters equally, and they affect adolescents more than younger children when they are perceived by the children. However, conflicts affect all groups when the mothers perceive them.     

Generalization of aggressive behavior in adolescent delinquent boys

The generalization of conditioned aggressive and nonaggressive responses in a group of six adolescent delinquent boys was investigated. Responses were reinforced in card games where a token reinforcement system with money as a back-up rinforcer was used. Conditioning of responses was rapid. Generalization, measured in terms of frequency of physical contact, was tested in a group game for which no reinforcement was given. Generalization occurred during aggressive contingencies. During nonaggressive contingencies, responses did not return completely to the baseline level.     

Serious delinquent behavior,sensation seeking,and electrodermal arousal

Low tonic skin conductance level (SCL) has been related, inconsistently, to both delinquency and sensation-seeking. This study tests the hypothesis that there is an interaction such that high sensation seeking delinquents, in particular, have low SCLs. Participants consisted of 335 boys from the Pittsburgh Youth Study classified as serious delinquents or controls based upon 10 years of prospectively collected self-report delinquency data. Participants' skin conductance was evaluated at age 16 along with several personality and neuropsychological measures. Both delinquency and sensation seeking were characterized by low SCL. However, there was no evidence to suggest that the presence of both of these factors together lead to especially low skin conductance levels. This finding is not explained by differences between the groups on measures of negative emotionality, IQ, socioeconomic status, or impulsivity.     

Effects of parenting,father absence,and affiliation with delinquent peers on delinquent behavior among African-American male adolescents

This study examined the effects of different aspects of parenting, father absence, and affiliation with delinquent peers on delinquent behavior in a cohort of African-American male adolescents. One round of survey data was collected from the youths' mothers or mother surrogates (N = 175) and two rounds of survey data were collected from the adolescents themselves. Analyses revealed that mothers' perceived control of sons' behavior was a deterrent of delinquent behavior, while other aspects of parenting (e.g., mother-son communication and relations) were not. The effect of mothers' perceived control was not mediated by adolescents' affiliation with delinquent peers. The effects of mothers' parenting variables and peer affiliation did not vary significantly by family structure, but socioeconomic disadvantage was more strongly associated with delinquent behavior in father-absent families. Though parenting effects were modest, this study suggests that African-American male adolescents are less likely to engage in delinquent behavior if they are closely monitored and supervised by their parents.     

Acculturation, peer relations, and delinquent behavior of Chinese-Canadian youth

Studies have reported that youth of Chinese descent in North America tend to have lower rates of delinquency. Some investigators have attributed this phenomenon to the restraining effects of Chinese culture. In this study, acculturation, peer relations, and delinquency were examined in a sample of Chinese-Canadian youth. The results revealed that adherence to Chinese culture was related to lower delinquency, whereas the opposite was true for North American acculturation. It was found that association with delinquent peers was positively related and attachment to peers negatively related to delinquency, as predicted by differential association and control theories, respectively. Moreover, acculturation was positively related to association with delinquent peers and attachment to peers. However, there was the unexpected finding that association with Chinese peers was positively related to delinquency. These seemingly contradictory findings demonstrate the dilemma experienced by Chinese youth in North America.     

Social policy and the role of the behavior analyst in the prevention of delinquent behavior

The purpose of this article is to encourage behavior analysts to expand their domain of interest and application to include the "social/political" contingencies that are developed and implemented by policymakers and lawmakers. Using the Vermont juvenile justice system as a prototype, examples are provided that focus on the tertiary, secondary, and primary prevention of delinquent behavior.     

Stressful events compromise control strivings during a major life transition

Prior research on stressful events has largely ignored their potential impact on motivational processes. This study prospectively examined the association of a stressful event with control strivings in the school-to-work transition. Five waves of data on stressful events, control strategies, and potential mediating variables were collected from an adolescent sample in Berlin (N = 420) during the year before high school graduation. The occurrence of a stressful event (death of family member, parent divorce) predicted a decline in general career-related and specific apprenticeship-related control strivings. This association was mediated by a decline in control-related means-ends beliefs. Proximity to the deadline of graduation exacerbated this association for apprenticeship-seeking control strivings, but this effect was buffered by usage of selective secondary control strategies (cognitive strategies to enhance commitment to a goal). Thus, stressful events can exacerbate challenges and require additional means of control striving.

Internet gambling, substance use, and delinquent behavior: an adolescent deviant behavior involvement pattern

Internet gambling among adolescents is a growing phenomenon that has received little attention to date. This study examines associations between Internet gambling and the severity of gambling, substance use (SU), and delinquent behavior among 1,870 Quebec students aged 14 to 18. The results show a higher proportion of Internet-gambling (IG) students reporting problematic substance use and delinquency, compared with nongamblers (NG) and non-Internet gamblers (NIG). Furthermore, a higher proportion of at-risk and probable pathological gamblers are found among IG compared with NIG. A moderating effect (Baron & Kenny, 1986) of the gambler categories (NIG, IG) was found in the relationship between the associated problems and the severity of gambling. Among IG, the severity of delinquency and of substance use contributes to explaining gambling severity whereas, among NIG, the severity of delinquency is the only factor that significantly contributes to such an explanation. Discussion of the results is based on Jessor, Donovan, and Costa's (1991) general deviance syndrome theory.     

Stressful life events and predictors of post-traumatic growth among high-risk early emerging adults

Stressful life events (SLEs) may elicit positive psychosocial change among youth, referred to as post-traumatic growth (PTG). We assessed types of SLEs experienced, degree to which participants reported PTG, and variables predicting PTG across 24 months among a sample of high-risk, ethnically diverse, early emerging adults. Participants were recruited from alternative high schools (n = 564; mean age = 16.8; 65% Hispanic). Multi-level regression models were constructed to examine the impact of environmental (SLE quantity, severity) and personal factors (hedonic ability, perceived stress, developmental stage, future time orientation) on a composite score of PTG. The majority of participants reported that positive changes resulted from their most life-altering SLE of the past two years. Predictors of PTG included fewer SLEs, less general stress, having a future time perspective, and greater identification with the developmental stage of emerging adulthood. Findings suggest intervention targets to foster positive adaptation among early emerging adults who experience frequent SLEs.     

Stressful life events, bipolar disorder, and the "kindling model"

A common misconception is that bipolar disorder is an endogenous process. However, previous research suggests a role for life events in the onset of and recovery from bipolar episodes. Yet, there remains some question as to whether the relationship between life events and onset changes over the course of the disorder as a result of the number of episodes an individual has experienced. Using a rigorous interview measure of stressful life events, the current study tested the kindling model (R. M. Post, 1992), which theorizes that major life events play a diminishing role over the course of illness in bipolar patients. Analyses revealed that the number of episodes experienced does not appear to have a significant effect on bipolar 1 patients' reactivity to external stressors. In addition, the results suggest that a more complex relationship exists among age, stress, and onset of new episodes than can be adequately explained by the kindling model.
