The intergenerational transmission of health-risk behaviors: adolescent lifestyles and gender moderating effects.

The present longitudinal study of 330 adolescents used structural equation models to investigate whether (1) health-risk lifestyles exist among adults and adolescents, (2) parents' health-risk behaviors influence adolescents' health-risk behaviors, and (3) intergenerational transmission occurs by way of a health-risk lifestyle, by direct transmission of specific behaviors, or through both mechanisms. To address these questions, we estimated several models. The findings were generally supportive of the expectations. Results of single factor measurement models provided modest evidence for the existence of an underlying health-risk lifestyle factor among parents and adolescents. Results of structural equation models also demonstrated that parents' health-risk behaviors were transmitted to adolescents both at the lifestyle factor level and the unique component level. These associations prevailed even after controlling for family social status. However, parents' health-risk lifestyles mediated the effect of family social status on adolescents' lifestyles, net of the direct effect of family social status on adolescents' lifestyle. In these two-parent families, the effects of parents' health-risk lifestyles on adolescents seems to have gender symmetry. The findings of the separate models for boys and girls demonstrated that (1) fathers' health-risk lifestyle affected only boys' health-risk lifestyle, whereas (2) mother's health-risk lifestyle affected only girls' health-risk lifestyle. A similar gender moderating effect was not found for specific health-risk behaviors. Implications of these findings for future research and theoretical development are discussed.

Tobacco, alcohol and drug use in eight- to sixteen-year-old twins: the Virginia Twin Study of Adolescent Behavioral Development.

OBJECTIVE: This study reports prevalences of lifetime and current alcohol, tobacco and drug use in adolescents; examines associations between substance use and a number of putative risk factors; and estimates the contribution of genetic, shared and unique environmental influences on substance use. METHOD: Substance use data were collected using the Child and Adolescent Psychiatric Assessment on a population sample of 1,412 male and female monozygotic and dizygotic twin pairs, aged 8 through 16, from the Virginia Twin Study of Adolescent Behavioral Development. RESULTS: Heritabilities were estimated to be 84% and 82% for liability to lifetime and current tobacco use, respectively. For alcohol use the role of genes and environment varied according to the context of reporting. Liability to lifetime alcohol use was estimated to be under environmental control, with 71% of the variation shared by members of a twin pair and 29% unique to individual twins. Lifetime alcohol use without the permission of a parent or guardian and current use of alcohol were predominantly explained by genetic factors (h2 = 72% and 74%). The role of genetic factors increased and that of unique environmental factors decreased with increasing severity of alcohol use. Lifetime use of any drug showed a heritability of 45%, with the shared environment accounting for 47% of the variation. Shared environmental factors explained most of the variation in marijuana use. CONCLUSIONS: Genetic factors explained a significant proportion of the variation in the use of tobacco, alcohol and other drugs. Shared environmental factors contributed significantly to lifetime alcohol use and other drug use.

The adolescent behavioral repertoire: its latent structure in the PACARDO region of Latin America.

In this study, the authors probed the latent structure of the adolescent behavioral repertoire (ABR) and estimated its sociodemographic correlates. The authors drew a nationally representative sample of 12,797 school-attending youth from the 7 countries in the PACARDO region of Latin America: Panama, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and the Dominican Republic. On the basis of the Behavioral Repertoire Self Report scale (Johanson, Duffy, and Anthony, 1996), the authors identified 5 primary dimensions, including religious behaviors, socializing, sports, home-based activities, and gender socialization activities. The authors found that the levels of involvement in these dimensions of the ABR varied across sociodemographic characteristics. The observed multidimensional structure of the ABR sets the stage for future research on adolescent health in relation to these behaviors and activities.

External validity of the new Devereux Adolescent Behavior Rating scales.

The discriminant and concurrent validity of the five new scales for the Devereux Adolescent Behavior Rating Scale (DAB) was explored using a heterogeneous sample of psychiatric and substance abuse patients. Consistent with predictions, the substance abuse patients scored higher on the Acting Out Behaviors (AOB) and Heterosexual Interests (HI) scales, and psychiatric patients scored higher on the Psychotic Behaviors scale. Gender differences also were found, including boys being rated higher on Acting Out Behaviors, and girls higher on Heterosexual Interests. The new DAB scales demonstrated sufficient concurrent validity using a thorough record review and a patient rating scale (the Child Behavior Checklist [CBCL]). The Neurotic/Dependent Behaviors scale (NDB) showed a consistent relationship with substance abuse and several other measures of more externalizing behaviors, in addition to the predicted relationships with anxious, tense, and dependent behaviors. The Withdrawn/Timid Behaviors scale (WTB) proved to be a purer measure of internalizing behaviors in both sexes.

Diet and adolescent behavior: is there a relationship?

Behavioral problems such as hyperactivity, learning disabilities, mental illness, aggressive and antisocial behavior, and juvenile delinquency have been purportedly linked to the potential influence of foods or nutrients. This article examines the scientific evidence of the relationship between food and behavior in children and adolescents. It highlights the implications for practitioners important to consider in the assessment of the relationship between diet and behavior.

The Devereux Adolescent Behavior Rating Scale: a tentative model of second-order factor structure across independent clinical samples.

The second-order factor structure of the Devereux Adolescent Behavior Rating Scale was examined in (a) a sample of 254 adolescents who were receiving residential treatment for severe emotional/behavior disorders and (b) an independent sample of 404 adolescents hospitalized for substance abuse. A plausible range of factors was estimated for each group through parallel and average partial analyses and suggested wither a two- or three-factor solution. Subsequent congruence analyses provided tentative support for a three-factor model: (a) undercontrolled/disruptive behaviors; (b) withdrawn/psychotic behaviors; and (c) needs approval/dependent behaviors. The third factor was poorly defined in the residential treatment sample, but extraction of the third factor increased the across-group replicability of the first two factors.

The Virginia Twin Study of Adolescent Behavioral Development. Influences of age, sex, and impairment on rates of disorder.

BACKGROUND: The Virginia Twin Study of Adolescent Behavioral Development is a cohort-longitudinal epidemiological study that uses the genetic twin design to study the development and maintenance of child psychiatric disorders. We determined the rates of DSM-III-R disorders, disorders with impairment, and age, sex, and comorbidity effects. METHODS: Families of 2762 white twins aged 8 to 16 years participated. Twins and their parents were asked systematically about risk factors and current psychiatric symptoms by means of investigator-based psychiatric interviews and questionnaires. The DSM-III-R diagnoses were made for major depressive disorder, separation anxiety, overanxious disorder, simple phobia, social phobia, agoraphobia, oppositional defiant disorder, conduct disorder, and attention deficit hyperactivity disorder. RESULTS: The 3-month point prevalence for any DSM-III-R disorders was 413 per 1000, and that for disorders with associated impairment was 142 per 1000. Emotional disorders with impairment occurred in 89 per 1000, with girls being more commonly affected; behavioral disorders had a prevalence of 71 per 1000, with boys being more frequently affected. The proportion with disorder who also had functional impairment varied across disorders; anxiety and phobic disorders were particularly likely not to be accompanied by impairment. Rates of emotional and behavioral disorders increased over the age range. There was extensive comorbidity among disorders. CONCLUSIONS: The prevalence rates and patterns of findings from this study of twins are consistent with those of other epidemiological studies, supporting previous findings of few differences in rates of psychiatric disorder between twins and singletons. The importance of including measures of functional impairment is evident by its effect on rates of disorder and patterns of comorbidity.

Primary care management of adolescent sexual behavior.

Adolescents continue to engage in sexual behaviors that place them at risk for sexually transmitted diseases, including HIV, and pregnancy. Recent advances in the prevention and management of sexually transmitted diseases and pregnancy may eventually lead to fewer negative consequences associated with adolescent sexual behavior. This paper discusses scientific and technologic advances in the management of adolescent sexual behavior such as the use of DNA amplification tests to detect genital chlamydial infection and the new female-controlled contraceptives.

The Virginia Twin-Family Study of Adolescent Behavioral Development: assessing sample biases in demographic correlates of psychopathology.

The Virginia Twin-Family Study of Adolescent Behavioral Development (VTSABD) is a current longitudinal study of psychopathology in 1412 pairs of 8-16-year-old Caucasian twins and their parents. The primary aim of the study is to evaluate family-genetic and environmental risk factors for major domains of psychopathology in families representative of the Virginia Caucasian population. In this report, we utilize census-derived indices of neighbourhood income and urban residence to identify departures from population representation arising at the time of family enrollment in the twin registry and family participation in a psychiatric interview. Furthermore, we consider whether demographic sample biases influenced prevalence rates of adult psychopathology (including major depression, generalized anxiety disorder, alcohol dependence, phobias, and panic disorder) in the VTSABD. Results indicated that families that enrolled in the twin registry (83% of those identified by Virginia schools) and that participated in the home interview (75% of those targeted) resided in urban and rural communities with a range of per capita income levels representative of the Virginia population. However, participation biases operated throughout the study and were primarily characterized by losses of families living in low income, urban communities. There was also a smaller number of families living in high income neighbourhoods that did not enroll in the twin registry or that indefinitely postponed the psychiatric interview. These biases had small effects on prevalence rates of adult psychopathology in the VTSABD sample, even though neighbourhood income was significantly related to a subset of adult diagnoses. We emphasize the usefulness of the census methodology in evaluating sample biases in population-based psychiatric genetic studies.

The adolescent behavioral repertoire as a context for drug exposure: behavioral autarcesis at play.

AIMS: The aim of this study is to investigate suspected behavioral autarcesis. Autarcesis refers to a mechanism of non-specific shielding from or immunity to infection or disease. Here, suspecting that some facets of the adolescent behavioral repertoire (ABR) might shield youths from early drug involvement, we studied recent-onset occurrence of first chances to try a drug and first actual drug use, expressed as a function of five observed ABR dimensions: religious, socializing, sports-related, gender socialization, and home-based activities. DESIGN AND PARTICIPANTS: Nationally representative samples of school-attending youths were drawn in Panama, the five Spanish heritage countries of Central America and the Dominican Republic (n = 12797). MEASUREMENTS: Drug involvement and ABR were assessed via anonymous self-administered questionnaires. FINDINGS: A religious activity dimension and a separate sports dimension were associated inversely with recent onset of adolescent drug experiences, and a socializing activity dimension was related to an increased occurrence of these experiences. For example, for each unit increase of the religious activity dimension of the ABR, there was an associated reduced occurrence of the first chance to try tobacco (OR = 0.75, 95% CI: 0.63-0.90, P = 0.002). Adolescents at higher levels of sports activities and home-based activities were less likely to experience recent-onset actual use of marijuana (OR = 0.45, 95% CI: 0.30-0.67, P < 0.001; OR = 0.56, 95% CI: 0.32-0.99, P = 0.048, respectively). CONCLUSIONS: The study evidence lends some support for behavioral autarcesis. Manipulation of selected ABR dimensions might help prevent or reduce adolescent drug involvement, enhancing autarcesis as a protective mechanism.

Promoting health through a developmental analysis of adolescent risk behavior.

Adolescents are the only U.S. population group not to improve morbidity and mortality since 1960. Social and behavioral etiologies of adolescent morbidity and mortality are best addressed in schools, since health care providers rarely are seen by teen-agers for other than organic health complaints. The relevance of physical, cognitive, and psychosocial development for adolescent risk-taking and their attendant health problems are discussed. Recognizing adolescent risk-taking as a means of achieving autonomy and identity, nurses and health educators can intervene to promote health-enhancing alternatives to achieve those ends. Social learning theory provides a basis for interventions to personalize the curricula, change behaviors, and shape the environment.

School-based clinic use and other factors affecting adolescent contraceptive behavior.

Adolescent risk taking, preventive behavior, and contraceptive use were investigated using a self-administered questionnaire in a sample of 260 inner-city high school students targeted by a school-based health clinic. Multivariate models consisting of individual and environmental variables significantly predicted sexual activity and contraceptive use. Older age at first intercourse, higher number of welfare benefits received by the household (including Medicaid, food stamps, and free or reduced price lunch), and use of the school-based clinic were significant positive predictors of more frequent contraceptive use by adolescents. Results of our study suggest that programs may be having some success in encouraging and enabling sexually active adolescents to use contraception and to use it more consistently. Rigorous program evaluations should help program planners and policy makers design and refine adolescent pregnancy-prevention efforts.

Student-school bonding and adolescent problem behavior.

Adolescent problem behavior, including substance use, school misconduct and delinquency, is a national concern. Implicit in the concept of middle school is the recognition that students who develop positive social bonds with their school are more likely to perform well academically, and refrain from misconduct and other antisocial behavior. However, little scientific attention has been given to the complex interactions between middle school students and the school environment. Prior to implementing a middle school problem behavior prevention program we conducted a survey in the seven middle schools in one US school district. Out of 4668 grade 6-8 students enrolled, 4263 (91.3%) completed the survey. Student-school bonding was positively correlated with school adjustment (r = 0.49) and perceived school climate (r = 0.77), but inversely correlated with problem behavior (r = -0.39 to -0.43). Problem behavior was significantly higher (P < 0.001) among males than females and among students in higher grades. Conversely, school bonding, climate and adjustment were significantly higher (P < 0.001) among females than males, but declined significantly from one grade to the next. The data support the conclusion that school bonding is associated with problem behavior. We describe the development of a multiple-component intervention in middle schools designed to increase student-school bonding and prevent problem behavior.

The Adolescent Behavior Checklist: normative data and sensitivity and specificity of a screening tool for diagnosable psychiatric disorders in adolescents with mental retardation and other development disabilities.

Individuals with mental retardation are almost twice as likely to demonstrate severe behavioral problems or symptoms of mental illness as are nonmentally retarded individuals. At present, however, the ability to diagnose a mental disorder in an individual with mental retardation is difficult, and instruments are needed to help facilitate this process. The Adolescent Behavior Checklist was developed with this purpose in mind. This self-report scale is used to assess the likelihood that an adolescent with mild mental retardation or borderline intelligence has a diagnosable mental illness. The 86-item yes/no self-report scale renders scores on eight subscales derived from DSM III-R. The checklist has been found to have good criterion and congruent validity and good test-retest reliability. Data regarding interrater reliability and the sensitivity and specificity of the scale are presented, as are implications for future research.

Early childhood television viewing and adolescent behavior: the recontact study.

In this Monograph, we report the follow-up of 570 adolescents who had been studied as preschoolers in one of two separate investigations of television use. The primary goal of the study was to determine the long-term relations between preschool television viewing and adolescent achievement, behavior, and attitudes. Using a telephone interview and high school transcripts, we assessed adolescent media use; grades in English, science, and math; leisure reading; creativity; aggression; participation in extracurricular activities; use of alcohol and cigarettes; and self-image. In each domain, we tested theories emphasizing the causal role of television content (e.g., social learning, information processing) as contrasted with those theories positing effects of television as a medium, irrespective of content (e.g., time displacement, pacing, interference with language). The results provided much stronger support for content-based hypotheses than for theories emphasizing television as a medium; moreover, the patterns differed for boys and girls. Viewing educational programs as preschoolers was associated with higher grades, reading more books, placing more value on achievement, greater creativity, and less aggression. These associations were more consistent for boys than for girls. By contrast, the girls who were more frequent preschool viewers of violent programs had lower grades than those who were infrequent viewers. These associations held true after taking into account family background, other categories of preschool viewing, and adolescent media use. One hypothesis accounting for the sex differences is that early experiences, such as television viewing, have greater effects when they counteract normative developmental trends and predominant sex-typed socialization influences than when they reinforce them. Adolescents in the study used both television and print media to support ongoing interests. Television content (e.g., entertainment, sports, or world events) predicted extracurricular activities, role models, and body image. The only evidence for possible effects of television as a medium was the positive relation of total viewing to obesity for girls. The medium of television is not homogeneous or monolithic, and content viewed is more important than raw amount. The medium is not the message: The message is.
