Aggression and delinquency: Family and environmental factors

Juvenile delinquency has become an increasing concern to society; aggressive behaviors are particularly harmful. This study examined parent and youth behaviors and personality types that may influence delinquent and aggressive behaviors. Youths were referred by the court to an intervention program; ratings of delinquency and aggression were derived from parent reports, self-reports, and court referral data. Results showed that high parent ratings of youth aggressiveness were related to high turmoil in the home and to youths' positive opinions of delinquent peers, while high aggressiveness of the youths' referring offenses was related to lax punishment. Developmentally, this suggests that in adolescence both the peer group and home influences are important in shaping different aspects of the youths' aggressive and delinquent behaviors.This study was partially conducted under University of Virginia Research Policy Council Grant No. 199505.

Effects of self-monitoring and perceived approval on delinquent behavior among Hong Kong adolescents

It has been established that perceived approval from relevant others is related to delinquent behavior. The aim of the present study was to investigate how this relationship was mediated by self- monitoring. Eight hundred twenty-eight students from Grade 7 to Grade 9 were asked to respond to a questionnaire that measured their self-monitoring, the frequency they committed delinquent acts, and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that self- monitoring wax an interacting factor between perceived approval and delinquency. On further path analyses, it was found that self- monitoring acted as a mediating factor, and that the relationship between delinquent behavior and perceived approval was more apparent among high self- monitoring individuals. The present study was based on data collected in the delinquency project by S. Lau and Kwok Leung.Received M.Phil. from University of Hong Kong and M.A. in education from Chinese University of Hong Kong.

Psychosocial differences between occasional and regular adolescent users of Marijuana and Heroin

Data on marijuana and heroin use were obtained from 969 adolescents in Hong Kong, part of them being offenders. Very high drug use prevalence rates were found, which is due to the unique population studied. All but two of the heroin users were incarcerated youth. Drug use frequencies were highly associated with psychosocial variables such as sensation seeking, peer drug use, family drug use, susceptibility to peer pressure, perceived control to gain access to drugs, intention to try other substances, and perceived adverse consequences of drug use. Interactions were found indicating, for example, that regularly marijuana using girls and occasionally heroin using girls were characterized by higher levels of sensation seeking and susceptibility to peer pressure than their male counterparts. Polysubstance use was generally related to high levels of psychosocial vulnerability factors. The exclusive use of marijuana was associated with high susceptibility to peer pressure and with perceived control to gain access to drugs. The findings reflect a complex interplay of psychosocial variables with substance use in adolescents that, however, cannot be generalized beyond this particular sample in Hong Kong.Received Ph.D. in Clinical Psychology from the University of North Texas.

Athletic Involvement and Adolescent Delinquency

Athough conventional wisdom suggests that organized sport deters delinquency by building character, structuring adolescents’ time, and providing incentives for socially approved behavior, the empirical evidence to date has been mixed. Based on a sample of approximately 600 Western New York adolescents, the present study examined how self-reported jock identity, school athlete status, and frequency of athletic activity differentially influenced a range of delinquent behaviors. Neither athlete status nor frequency of athletic activity predicted these behaviors; however, jock identity was associated with significantly more incidents of delinquency. This finding was robust across both gender and race. Follow-up analyses indicated that jock identity facilitated both minor and major delinquency, with major delinquency effects for white but not black adolescents.

Parental Knowledge and Youth Risky Behavior: A Person Oriented Approach

Most studies isolate the effects of one knowledge-related behavior on youth outcomes. This study explores the relationship between subgroups of mother–youth dyads that use specific combinations of parental knowledge-related behaviors and youth risky behavior. Using a sample of 796 rural 6th graders (53 % female), we assessed mother and youth reports of maternal knowledge, active parent monitoring efforts, youth disclosure, parental supervision, and the amount of parent–youth communication to identify five knowledge latent classes: High-Monitors, Maternal Over-Estimators, Low-Monitors, Communication-Focused, and Supervision-Focused. Delinquency, antisocial peers, and substance use were associated with increased odds of membership in the Supervision-Focused class, relative to the High Monitors. Membership in the Low Monitors and Maternal Over-Estimators classes was associated with unhealthy attitudes towards substances and for Low Monitors, substance use. The discussion focuses on the value of using a person-oriented approach to understand parental knowledge and risky behavior during early adolescence and intervention implications.     

Depression and substance use in two divergent high school cultures: A quantitative and qualitative analysis

Research has generally concluded that adolescent depression and substance use are strongly interrelated, but has rarely considered how this relationship may vary across diverse populations. In this study, we used quantitative and qualitative methods to explore the relationships among depression and cigarette, alcohol, marijuana, and harder drug use across two culturally disparate environments: a suburban and an inner-city high school. Our sample included 164 suburban and 242 inner-city high school students. The students completed Kovacs' Children's Depression Inventory of 1985 and substance use measures derived from various sources. In-depth semistructured interviews were conducted with subjects who scored in the top 10% of the CDI (N=19) from both schools. Our quantitative findings indicated a positive association between depression and cigarette, marijuana, and harder drug use among the suburban students, and no association between depression and the use of any substances for the urban students. There were no significant differences in levels of reported depression across samples. However, with the exception of marijuana use, suburban students reported greater involvement in substance use than urban students. Our qualitative analyses suggest that across-school differences in the relationships among depression and substance use may be related to the varied meanings of depression and substance use that are informed by cultural context.The research was funded by the National Institute of Drug Abuse (NIDA), Grant No. 1 R01 DA-06844, Perry London, principal investigator.

Delinquency and family life among male adolescents: The role of ethnicity

This study addresses the role of ethnic and racial diversity in the relationship between family processes and delinquency. The study evaluates the overall role families play in the etiology of delinquency across different ethnic/racial groups, and investigates the relative role of specific issues such as family involvement, family attachment, and family control among Hispanic, African American, and white male adolescents. This analysis utilizes two waves of data from the Rochester Youth Development Study, a longitudinal project investigating the causes and correlates of delinquency among a high-risk urban sample of youth. Results of this study indicate that family variables as a group are more important in constraining delinquency for Hispanic adolescents. In addition, the relative influence of particular family processes on delinquent conduct appears to differ among diverse populations. We also find that living in a single-parent home has less impact on family processes than living in a situation of economic hardship.Prepared under Grant No. 86-JN-CX-0007 (S-3) from the Office of Juvenile Justice and Delinquency Prevention, Office of Justice Programs, U.S. Department of Justice, Grant No. 5 R01 DA05512-02 from the National Institute on Drug Abuse, and Grant No. SES-8912274 from the National Science Foundation.

The Longitudinal Relationships Between Rural Adolescents’ Prosocial Behaviors and Young Adult Substance Use

While many adolescents and young adults experiment with substances (e.g., alcohol, cigarette smoking, marijuana), recent research suggests that rural youth and young adults may be more at risk for substance use than their urban counterparts. This study was designed to examine the longitudinal relationships between rural adolescents’ prosocial behaviors and substance use in young adulthood. Furthermore, we examined the potential mediating effects of adolescent substance use, academic investment, and delinquency. Rural youth (N = 531; 263 girls) were surveyed in grades 10–12 (Time 1; M age = 16.17; SD = .91) and again in early adulthood (Time 2). Measures of prosocial behaviors, substance use, academic investment, and deviant activities were assessed at Time 1. At Time 2, measures of marijuana use, cigarette smoking, and getting drunk were administered. Overall, the findings showed that rural adolescents who frequently exhibit prosocial behaviors are less likely to engage in substance use in young adulthood than those who exhibit relatively low levels of prosocial behaviors. These findings indicate that prosocial behaviors may have positive health consequences, establishing behavioral trajectories that lead to lower levels of risky health behaviors in adulthood in rural populations.     

Peer vs. parental influence in substance use among hispanic and Anglo children and adolescents

The relative influence of peer and parental influence on youths' use of alcohol and other drugs is explored among 446 Anglo and Hispanic youths, ages 9–17. Current users and abstainers are similar in age and gender. Among both groups, parental influence is more profound than that of peers. However, substance users, compared to abstainers, are more influenced by peers. Level of marijuana use by youths' friends is the most reliable predictor of drug use. Youths having viable relationships with parents are less involved with drugs and less influenced by drug-oriented peers.Funded by a grant (A-003-2) from the California Department of Alcohol and Drug Programs, R.

Delinquent behaviors and male adolescent development: A preliminary study

Commonly identified developmental tasks of male adolescence were examined for their relationship to delinquent behavior during adolescence among a general sample of 11-to 18-year-old males (N=337). Evaluations of the prevalence and mean level of delinquent acts across the age groups confirms previous suggestions that delinquent behavior follows the adolescent years quite closely. Measures of three primary developmental domains—family relations, social relations, and educational/vocational orientations—were taken and correlated with delinquent behavior across three substages of adolescence. The patterns of correlations suggest there is support for the view that a substantial portion of delinquent behavior is tied to struggles with adolescent development tasks.This work was conducted while the author was a Clinical Research Training Fellow in Adolescence (funded by T32 MH 14668) at the Institute for Psychosomatic and Psychiatric Research and Training, Michael Reese Hospital and Medical Center, in a program also sponsored by the Departments of Behavioral Science and Psychiatry, University of Chicago and the Adolescent Program of the Illinois State Psychiatric Institute.

Effects of self-concept and perceived disapproval of delinquent behavior in school children

It is argued that a multidimensional approach to self-concept may reveal intricate relations between self-concept and delinquent behavior, and that perceived approval of delinquent behaviors from referent groups may be related to the frequency of their occurrence. To evaluate these hypotheses, 1668 students from Grade 7 to Grade 9 responded to a questionnaire that measured their general self-esteem; their self-concept with regard to physical ability, social ability, physical appearance, and academic ability; the frequency they committed 15 delinquent acts; and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that poor academic self-concept and poor relationship with school and parents were related to a higher frequency of delinquent behavior. However, a higher frequency of delinquent behavior was related to a more positive selfconcept with regard to social ability and physical ability. Finally, higher perceived approval from parents and peers was related to more delinquent behavior. Implications of these findings for identifying the antecedents and consequences of delinquent behavior were discussed.Received his Ph.D. from University of Illinois in social, industrial, and organizational psychology.

Parenting factors,social skills,and value commitments as precursors to school failure,involvement with deviant peers,and delinquent behavior

Elements of social control theory were combined with social learning theory to construct a model of delinquency which specifies the manner in which parenting factors, social skills, value commitments, and problems in school contribute to association with deviant peers and involvement in delinquent behavior. The model was tested using a sample of 61 families, each of which included a seventh grader. Questionnaire responses and coded videotaped family interaction were employed as measures of study constructs. The results largely supported the proposed model.This work was supported by Research Grants DA 05347 from the National Institute on Drug Abuse, MH 43270 from the National Institute of Mental Health, and MCJ 190572 from the Bureau of Maternal and Child Health, Department of Health and Human Services.Received Ph.D. in sociology from Florida State University.

Personality,cognitive, and interpersonal factors in adolescent substance use: A longitudinal test of an integrative model

This study tests a multidimensional model of adolescent drug use. The model incorporates sociodemographic variables, personality variables (state and trait anxiety, depressive mood, and sensation seeking), cognitive variables (knowledge, attitudes, and intentions), interpersonal factors (relationships with peers and parents), and the availability of drugs. The model was tested in a longitudinal study, comprising two phases. A total of 1446 high school students served as subjects. The role of cognitive (attitudinal) and interpersonal factors (relationships with parents and peers) was confirmed. In addition, sensation seeking proved to have significant predictive power. Anxiety, depression, and sociodemographic factors, by contrast, had virtually no influence. Availability had a minor effect. The multidimensional explanation was validated longitudinally. The factors related to drug use at the first phase predicted use at the second. This multidimensional explanation accounted for the use of various substances, suggesting that different substances—whether legal or illegal—share a common multidimensional explanation.This work is based on the doctoral dissertation of Zipora Barnea supervised by Meir Teichman and Giora Rahav, and submitted to the Tel-Aviv University.

Delinquent Behavior of Dutch Rural Adolescents

This article compares Dutch rural and non-rural adolescents’ delinquent behavior and examines two social correlates of rural delinquency: communal social control and traditional rural culture. The analyses are based on cross-sectional data, containing 3,797 participants aged 13–18 (48.7% females). The analyses show that rural adolescents are only slightly less likely to engage in delinquent behavior. Furthermore, while rural adolescents are exposed more often to communal social control, this does not substantially reduce the likelihood that they engage in delinquent behavior. Concerning rural culture, marked differences appeared between rural and non-rural adolescents. First, alcohol use and the frequency of visiting pubs were more related to rural adolescents’ engagement in delinquent behavior. Second, the gender gap in delinquency is larger among rural adolescents: whereas rural boys did not differ significantly from non-rural boys, rural girls were significantly less likely to engage in delinquent behavior than non-rural girls. However, the magnitude of the effects of most indicators was rather low. To better account for the variety of rural spaces and cultures, it is recommended that future research into antisocial and criminal behavior of rural adolescents should adopt alternative measurements of rurality, instead of using an indicator of population density only.     

Risk and Protective Factors Associated with Alcohol,Cigarette, and Marijuana Use During Adolescence

The purpose of this study was to increase the knowledge base of adolescent substance use by examining the influences of risk and protective factors for specific substance use, namely alcohol, cigarettes, and marijuana. Participants included 271 adolescents and their primary caregivers referred for mental health services across North Carolina. A series of hierarchical multiple regressions showed that the relative influences of risk and protective factors differed depending on the target substance in some cases. History of parental felony predicted use of all 3 substances, although the direction of association was substance specific. Parental behavioral control (how families express and maintain standards of behavior) was predictive only of cigarette and marijuana use, not alcohol use. The different links among risk factors, protective factors, and specific substance use are discussed, and recommendations for both mental health and substance use professionals are offered.She received her M.A. in Psychology from Wake Forest University and is currently a doctoral student in Clinical Psychology at the University of North Carolina at Greensboro.

The nature of the association between parental rejection and delinquent behavior

A panel design with approximately 300 adolescents was employed to investigate the relationship between parental rejection and delinquency. Previous studies have failed to control for potentially confounding family factors and have ignored the possibility that the causal priority is from delinquency to parental rejection, rather than the reverse. Parental rejection continued to show a moderate association with delinquency after relevant controls were introduced. The results were the same across sexes. LISREL was employed to estimate the parameters of the reciprocal relationship between parental rejection and delinquency. Analysis indicated that the predominant causal flow is from parental rejection to delinquency.Research interests: the etiology of adolescent depression, substance abuse, and delinquency; identification of factors which influence parenting practices.Research interests: the causes, treatment, and prevention of adolescent depression and substance abuse.Research interests: causes of adolescent and adult substance abuse; antecedents, and consequences of domestic violence.     

An examination of types of delinquency through path analysis

Relationships between father's occupation, delinquent peer association, tendency to neutralize, and self-reported delinquency are explored in a path model. Self-reported delinquency are categorized into Minor, Predatory, and Aggressive delinquency. The effect of this division is analyzed among Mexican Americans and Anglo college students (N=694). The structure of the resulting path models remained similar across these subsamples, although there was some variation in the strength of the relationships. The effect of father's occupation was minimal. The strongest relationships were between neutralization and delinquency, controlling for delinquent peers and for father's occupation, which decreased as the seriousness of the delinquency increased. Additionally, neutralization was more strongly related to delinquency among Anglos than among Mexican Americans, explaining 39% of the variation in delinquency among Anglos, but only 28% among Mexican Americans. Association with delinquent peers, however, was more strongly related to delinquency among Mexican Americans.Received his Ph.D. from Oklahoma State University.

Depression and suicidal behavior among delinquent females

Depressive symptomatology and suicidal behavior were evaluated in a multiethnic sample of 48 delinquent females through ratings on self-reports and probation officers' reports. Psychological functioning of the subjects was also evaluated through the Diagnostic Interview for Borderlines, the Rorschach, and the WAIS or WISC-R in order to identify delinquent personality patterns. Four personality patterns were identified: the borderline, the antisocial, the neurotic, and the socialized delinquent personalities. A chi-square analysis of the data demonstrated that level of depression and frequency of suicidal behavior were both significantly related to personality patterns. Level of depression was also significantly related to ethnicity, but not to socioeconomic status. The results have implications for assessment and treatment of delinquent females and also raise issues concerning the interaction of personality, cultural factors, and delinquent behavior which should be addressed in future research with larger, socioculturally diverse samples.This research is based on the author's doctoral dissertation and was supported by a Pre-Doctoral National Research Service Fellowship award from the National Institute of Mental Health.Received her Ph.D. from the University of California at Berkeley in 1980.

Why do adolescents use drugs? Age,sex, and user differences

This paper makes four points: (1) There is substantial substance use among adolescents in our large rural southwestern sample. (2) Adolescents explain their drug use with five kinds of reasons (i.e., Belonging, Coping, Pleasure, Creativity, and Aggression). (3) Different reasons for using drugs are related to frequency of substance use. (4) There are age, gender, and user differences in the reasons adolescents have for their drug use. After summarizing traditional ways of thinking about drug use, we describe an alternative way for examining such behavior. We use this approach to study relationships between drug use reasons and age, gender, and substance use in 2637 6th–12th-grade students. We then discuss prevention and treatment implications of this research.Received Ph.D. from University of California at Berkeley in personality psychology.

Suicidal ideation in adolescence: Depression,substance use,and other risk factors

The interrelationships of depression and suicide with adolescent drug use, delinquency, eating disorders, and the risk factors for these different problems were investigated among 597 9th and 11th graders in an urban high school. There is a strong association of drug use with suicidal ideation among girls, and a stronger relationship with attempts among girls and boys. Suicidal youths are ill-adjusted and display a lack of attachment and commitment to family and school. Causal models indicate that poor interpersonal interactions with parents, absence of peer interactions, and life events lead to depression, which in turn leads to suicidal ideation. Depressive symptoms are the strongest predictors of suicidal ideation. Among females, depression predicts drug involvement, and in turn, drug use increases suicidal ideation. Drug use is only one class of problem behaviors that constitutes a risk factor for suicidal behavior in adolescence. Delinquency and eating disorders also have direct effects on suicidal ideation beyond those of depressive affect. As for drug involvement, these problem behaviors are more predictive of suicidal behavior among girls than boys. Similarity and specificity of the predictors for problem behaviors within and between the sexes are discussed. Although young women use drugs to handle feelings of depression, drug use appears ineffective in the long run in relieving these depressive feelings. Understanding the dynamics of suicidal ideation in adolescence has important public health implications, since ideation is a strong predictor of attempts, especially among females.Revised version of a presentation at the Workshop on Adolescent Depression, Princeton, NJ, June 3, 1987.Work on this research has been partially supported by Research Grants DA00064, DA01097, DA03196, and DA02867, and by Research Scientist Award DA00081 from the National Institute on Drug Abuse; and awards from the John D. and Catherine MacArthur Foundation and the Research Foundation for Mental Hygiene, New York State Psychiatric Institute.
