A model of parental involvement in adolescent drinking and driving

This article presents a model of parental involvement in prevention of teenage drinking and driving. Research findings are reviewed on why adolescents drink and drive, and what parents' knowledge, attitudes, and practices are related to youthful impaired driving. Reasons for parents' ineffectiveness at intervening to prevent their teenagers from drinking and driving are described. It is suggested that parents' effectiveness at preventing alcohol use and alcohol-impaired driving among their teenagers depends upon their stage of involvement. The different stages of parental involvement are defined as awareness, acceptance, action, and consequences. The specific components of these stages are described, and evidence is presented indicating that parents tend to be unaware of the true extent and nature of teen drinking, and thus less prone to acceptance and action.Received Ph.D. in social psychology from Syracuse University.

Parental role in teenage driving

Students in 75 high schools in seven states participated in a questionnaire survey. The results showed that high school students want to become licensed as soon as possible and that parents are important in teaching them to drive. Once licensed, the majority of students have their own cars, though they do not typically pay the majority of the costs. Seventy-one percent of licensed students who do not have their own cars reported that they can usually or always use a family car. Most students, particularly younger ones and females, reported that their parents expect them to conform to certain rules or restrictions when driving and when riding as passengers. The most common restrictions were that their parents asked them not to drive after drinking, to tell parents where they were going and with whom, and to be home at a certain time. Students were far less likely to report that their parents required that they wear seat belts.This work was supported by the Insurance Institute for Highway Safety.Received a Ph.D. in experimental psychology from Yale University.

Impact of higher alcohol prices on alcohol-related attitudes and perceptions of suburban,middle-class youth

This study investigated the potential effects of alcohol price increases on alcohol-related attitudes and perceptions of youth. Data were collected through a survey of high school students conducted after the federal excise taxes on alcohol beverages were increased in January 1991. Survey data lend support to previous research showing that higher alcohol prices contribute to lower alcohol consumption by youth, as well as to a decrease in related problems such as driving while intoxicated. Survey data also suggest that a price of around $7.50 for a six-pack of beer or a four-pack of wine coolers would discourage purchases by youth. Further studies are called for to substantiate and to expand on these findings with more diverse adolescent populations.Received M.P.H. in health education from University of North Carolina at Chapel Hill.

Parents’ Communication with Adolescents About Sexual Behavior: A Missed Opportunity for Prevention?

Parents may wait to talk to their teens about sexuality until they believe their child is in a romantic relationship. To examine this, telephone surveys were conducted with 1069 parents of adolescents. Measures assessed parents’ perception of teens’ romantic involvement and parent-child communication about several sexuality topics. Multivariable regression models determined the odds of talking about each topic among parents who reported their teen had been in a romantic relationship compared to those who did not. Most parents reported talking at least a moderate amount about some sex-related topic. Parents who believed their teen had been romantically involved were more likely to have discussed most of the topics examined here (ORs=1.64 – 2.56). For some topics, associations were more pronounced among parents of younger teens. Findings suggest that parents may miss important opportunities to influence behavior, and should initiate conversations about sexuality before they believe their child to be romantically involved.Assistant Professor at the University of Minnesota.

Factors related to cigarette smoking during adolescent pregnancy

Previous research suggests that maternal smoking during pregnancy remains prevalent, particularly among adolescents. However, little is known about the factors related to smoking during adolescent pregnancy. The goal of the present study is to identify intrapersonal, familial, and peer factors that are related to smoking during adolescent pregnancy, and to determine the relative degree to which they affect this behavior. Interviews were conducted with 241 unmarried pregnant adolescents who planned to carry their pregnancies to term. Consistent with previous studies, 27% of the respondents reported daily smoking during pregnancy, and whites reported higher rates of use than members of other racial groups. Smoking during adolescent pregnancy was related to intrapersonal, familial, and peer factors. The results of a regression analysis suggest that perceived parental disapproval of smoking during pregnancy, friends' cigarette use, and race play a particularly important role in this behavior. The implications of these findings for preventive programs are discussed.Research reported here and the preparation of this report were supported by Grant DA-05208 from the National Institute on Drug Abuse.Received M.A. in sociology from the University of Washington.

Perceived attachments to parents and peers and psychological well-being in adolescence

This paper reports the findings from a study of 935 adolescents' perceived attachments to their parents and peers, and their psychological health and well-being. Perceived attachment to parents did not significantly differ between males and females. However, females scored significantly higher than males on a measure of attachment to peers. Also, relative to males, they had higher anxiety and depression scores, suggesting poorer psychological well-being. Overall, a lower perceived attachment to parents was significantly associated with lower scores on the measures of well-being. Adolescents who perceived high attachments to both their parents and peers had the highest scores on a measure of self-perceived strengths. In this study, adolescents' perceived attachment to peers did not appear to compensate for a low attachment to parents in regard to their mental ill-health. These findings suggest that high perceived attachment to parents may be a critical variable associated with psychological well-being in adolescence.Received M.Sc. in psychology from the University of Otago, Dunedin, New Zealand.

Family contexts of pubertal timing

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

Indicators of rural youth drug use

The relationships between personal substance use, health beliefs, peer use, sex, and religion were examined using data collected from 265 middle school students in rural northern Michigan and northeastern Wisconsin in January and February 1984. A positive correlation between peer and personal drug use was established. A relationship was also found between health beliefs and personal substance use. In addition, a regression model was able to account for a statistically significant amount of the variance of alcohol, marihuana, and cigarette use in the target population. Recommendations are made concerning future research, methods of improving health education program development, and possible target areas for psychotherapy.An earlier version of this paper was presented at the 1985 annual meeting of the American Public Health Association, Washington, DC.Received Ph.D. in Health Education from The University of Michigan.

Perceived parental rearing practices and styles of coping

In order to study the relation between parental rearing practices and coping dispositions, 75 females and 65 males completed the Children's Report of Parental Behavior Inventory and the COPE, a measure of general coping dispositions. Those who reported their parents had an authoritative rearing style (warmth and nurturance coupled with close monitoring and age-appropriate demandingness) used more social support and problem-focused coping than those who reported their parents used other rearing styles. In general, perceived parental warmth was related to the greater use of social support and problemfocused coping. Parental firm control was associated with increased problemfocused and reduced emotion-focused coping. The findings are discussed in the context of parental rearing styles indirectly influencing coping dispositions through their impact on feelings of competence and personal control.This research is based on a masters thesis conducted by the first author under the direction of the second author.

Changes in college students' use and abuse of alcohol,and in their attitudes toward drinking over the course of their college years

Using a November 1987 random sample of 526 undergraduate students attending a midsized, private, midwestern university, this study examines changes in students' alcohol use, alcohol abuse, and attitudes toward drinking over the course of their college careers. This research provides an empirical examination of the supposition that people begin college in an adolescent-like phase in their development and graduate from college in a decidedly more adult-like developmental phase. The data suggest that women appear to mature throughout the college years, gradually progressing toward an adult-like developmental state, at least insofar as their drinking patterns and alcohol-related attitudes are concerned. Men, on the other hand, demonstrated no significant changes over the course of their college careers, suggesting that college may represent little more than a period of protracted adolescence for them.Received Ph.D. in sociology from Washington University in St. Louis. Research interests include alcohol and other drug studies, sexual behavior, HIV/AIDS, and mass media.     

Men and Women’s Attachment and Contact Patterns with Parents During the First Year of College

Attending a university involves change and transition and an opportunity to study older adolescents’ attachment. The current study explored potential gender differences in both older adolescents’ need-and nonneed-based interactions with parents and their perceptions of attachment quality. Results indicated that although females did not initiate significantly more need-based contact with parents than males, they received significantly more need-based contact than males that was initiated by their parents. On the other hand, females both initiated and received nonneed-based contact with parents more than males. Consistent with attachment theory, parent–child need- and nonneed-based interactions were related to one’s perceived quality of attachment. Results indicated that adolescent attachment involves both need- and nonneed-based parent–adolescent interactions. The pattern of findings suggests that adolescent males and females may show attachment in different ways.This research is based on the first author’s master’s thesis at American University under the supervision of the second author.Department of Psychology, American University, Washington, DC.

Gender differences associated with young people's emotional reactions to sexual intercourse

The differences between male and female adolescents' emotional reactions to their most recent occasion of sexual intercourse were examined. The sample included 932 sexually active Australian secondary school students who completed a self-report questionnaire concerning their sexual behavior. The majority of young people reported that they felt happy or good following their most recent occasion of sex. Females were more likely than males to report negative emotions such as feeling bad and used, but there was no difference between the percentage of males and the percentage of females who reported feeling guilty. Girls were more likely to feel bad, used, or guilty last time if they were drunk/high or had sex with someone who was not a steady partner. Boys who had sex with someone other than a steady partner last time were more likely to feel guilty. Peer and parental influences were also associated with feelings of guilt. Girls who were more confident that they could talk to one of their parents/guardians about sex, and boys who believed that most of their peers were sexually active, were less likely to have felt guilty.Received B.A. (Hons) from University of Queensland.

Alcohol use among college students: Some competing hypotheses

This paper presents a longitudinal study of alcohol use among college students. Three hypothesized predictors of alcohol use are found to have an independent effect when the other predictors and prior drinking are held constant: the drinking context of the dormitory living group, informal social involvement in college, and lack of commitment to religious and academic values. These predictors are also related to the onset of drinking during the freshman year for those who entered college as abstainers. The pattern varies somewhat for males and females, with the dormitory contextual effect larger for females. Formal involvement in college activities and psychological stress have no independent effect on drinking. The results are discussed in relation to previous work on alcohol use.This research was supported in part by NIAAA Grant AA02863 and NIMH Grant MH28177 and Veterans Administration Research funds.Received Ph.D. in sociology from Stanford University in 1976.

Sexual risk behavior,knowledge, and condom use among adolescents in juvenile detention

This paper reports on sexual behavior, knowledge of sexually transmitted diseases (including AIDS) and condoms, and condom use among African-American and white incarcerated adolescents in Seattle, Washington. One hundred nineteen adolescents in a juvenile detention facility completed questionnaires that assessed their lifetime and recent sexual behaviors, an objective test of disease and condom knowledge, attitudes and norms regarding condom use with steady and casual partners, prior condom use, and intentions to use condoms. The results indicate that these adolescents are at high risk by a number of indicators: They have a high average number of partners, have unprotected vaginal and anal sex, and many have sex with known or suspected drug users. Their overall knowledge of condoms and sexual transmitted diseases risks is high, but high knowledge is not correlated with positive attitudes; for one attitude measure, high knowledge is significantly correlated with negative attitudes toward condom use. These findings suggest that programs designed solely to increase knowledge are unlikely to effect behavior change.This research presented in this paper was supported by a research grant from the National Institute of Allergy and Infectious Diseases.Received Ph.D. in social psychology from the University of Washington.

Sixth Graders’ Conflict Resolution in Role Plays with a Peer,Parent, and Teacher

This study used conflict resolution role play vignettes and self-report surveys of 450 New York City 6th graders to examine associations between adolescents’ conflict resolution efficacy and social skills. Vignettes covered 3 social contexts, conflict with a peer (disagreement over activities), with a parent (raise in allowance), and with a teacher (low grade on report). Effective and ineffective strategies for resolving these conflicts were coded from the videotaped interactions. Adolescents were more often effective in resolving conflict with peers than with parents (χ²(1) = 7.10, p < .01). Strong communication skills cut across interpersonal context as associated with effective resolution. Assertiveness and absence of aggression were associated with effective conflict resolution in vignettes with peers. Assertiveness was also associated with effective conflict resolution in vignettes with parents, however nervousness was unexpectedly found to facilitate conflict resolution in vignettes with parents. Only skills observed within a particular context were associated with effective resolution in that context; self-report skills and cross-context observed skills were not associated with efficacy. Implications for implementation and evaluation of social skills curricula and conflict resolution process are discussed.An earlier version of this paper was presented at the meetings of the Society for Research on Adolescence, New Orleans, LA, April 2002Received Ph.D. in Developmental Psychology from Teachers College, Columbia University in 2004.

Maternal employment and adolescent sexual behavior

This study investigated whether maternal employment would be associated with teenage sexual attitudes and behaviors likely to increase the probability of teenage pregnancy. Female subjects whose mothers were employed outside the home during the high school years (a) had a greater tendency to begin sexual relations before age 19, (b) expressed less concern regarding the risk of unintended pregnancy, and (c) scored lower on an objective test of their practical knowledge about contraception.Received Ph.D. in social psychology from the University of Washington.

Sex differences within the family: Studies of adolescent and parent family interactions

Sex differences in verbal family interactions were investigated in a group of 79 adolescents and parents from normal and psychiatric settings. The analyses were designed to study these differences in both generations, parent and adolescent. Parent and adolescent interactions with one another were observed in a semistructured, revealed-differences family discussion. All of the individual speeches were then scored with our Constraining and Enabling Coding System (CECS). Initial predictions involved both adolescent and parent differences. These hypotheses were only partially confirmed. The strongest findings pertained to parent sex differences, as we found strikingly higher levels of cognitive enabling speeches expressed by fathers and significantly more speeches addressed to fathers. We discuss several alternative interpretations of these findings. Perspectives included in our considerations are direction of effect and influences of task/context upon the expression of family sex differences.This study was supported through a grant from the National Institute of Child and Human Development (NICHD Grant No. R01 HD18684-02) and a Research Scientist Development Award No. 5 K-02-MH-70178 (Dr. Hauser) from the NIMH.Received M.D. from Yale University and Ph.D. from Harvard University (psychology).

Consistency of adolescents' self-report of sexual behavior in a longitudinal study

This study examines three issues relevant to adolescent self-reported sexual behavior: the extent to which adolescents rescind reports of sexual intercourse, changes in reporting of lifetime sexual intercourse, and changes in reported age at first sexual intercourse. Data come from a three-year longitudinal study of health-compromising behaviors among a cohort a 758 rural adolescents. Students completed a self-administered questionnaire on health behaviors annually in eighth, ninth, and tenth grades. Findings show that 88.8% of students in eighth grade and 94.3% in ninth grade who reported having had sexual intercourse gave the same answer in a subsequent year. Approximately 15% of students reported fewer numbers of lifetime sexual intercourse experiences in tenth grade than they did in ninth grade. Age at first sexual intercourse was reported inconsistently by 67% of the students. Inconsistency rates differed by racial-gender groups, question sensitivity, and prior sexual experience.Received Ph.D. from Johns Hopkins University.

Antecedents of collegiate drinking

A model designed to explain variations in the use of alcohol among undergraduates draws together three categories of variables: (1) sociocultural—race, sex, and population of student's hometown; (2) familial characteristics—father's occupation, parents' marital status, and closeness to a problem drinker; and (3) the onset of student drinking—age at first drinking and extent of drinking at its onset. A 10% random sample was drawn from the undergraduate students enrolled in two state-supported universities in the southeastern U.S. The present analysis focuses on 856 nonmarried, full-time undergraduate students. Overall, the findings show that race, degree of closeness to a problem-drinker, age at the onset of drinking, and its extent markedly influence the level of alcohol consumption among undergraduates. The strongest overall predictor of undergraduate drinking is the extent of adolescent consumption.Received M.A. from the University of North Carolina at Greensboro.

A cross-cultural comparison of sociopsychological factors in alcohol use among adolescents in Israel,France, and the United States

The correlates of alcohol use by adolescents are compared in three cultures with different prevalences of alcohol use: France, with high prevalence; Israel, with low prevalence; and the United States, in the middle. In all three countries, significant others, parents and peers, are more powerful predictors of alcohol use than are the adolescent's personal attributes, such as attitudes, behaviors, and demographic characteristics. Cross-cultural differences appear in the relative importance of parents and peers and in the structure of influence of parents and peers as role models. Parents are more important role models in Israel than in the other two cultures, while peers are more important in the United States than in France or in Israel.This research was partially supported by Research Grants DA01902, DA00064, and Research Scientist Grant K05-DA00081 from the National Institute on Drug Abuse, and by the Center for SocioCultural Research on Drug Use, Columbia University.Received Ph.D. from Stanford University.
