Prior research has pointed to several distinct processes that may affect the timing of first intercourse among adolescents. In the present study, the role of six hypothesized processes was assessed in a sample of 289 rural adolescent boys and girls. Results support the importance of family socialization and problem-behavior for both sexes, the role of biological factors for boys, and the role of social control processes for girls. Two other hypothesized influences—social class and poor psychosocial adjustment—were not supported in either gender. These results indicate that multiple processes influence the timing of first intercourse; thus, they underscore the need for eclectic predictive models that incorporate the multiplicity of influences.Received Ph.D. in Human Development from the University of Chicago.

Early adolescence is a period of the life course involving high levels of challenge that are stressful for some, perhaps resulting in depressive symptoms. In this study, adolescents were divided into four groups based on indices of depression and negative life events. Group differences in coping style, mastery, optimism, and social resources as well as group differences in patterns of change were investigated. Participants were 458 adolescents in sixth and seventh grade from a rural working class community. Subjects were assessed twice over a one-year period. Analyses revealed that the four groups were characterized by different levels of coping and social resources. Asymptomatic youth reported higher levels of optimism, mastery, active coping, and more positive relationships with parents and peers than did symptomatic adolescents. These same characteristics distinguished the resilient adolescents from the vulnerable adolescents, suggesting potential stress-buffering effects. One year later, the adolescents who were low on both depressive symptoms and negative life events continued to report more individual and contextual resources than the adolescents in the other groups.This research was supported by a grant from the William T.

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.

The present investigation explores the relationship between adolescent autonomy and parental stress among families with children aged 10–17. Independent measures were obtained from parents and children. Parents of early adolescent children reported significantly more stress than parents of preadolescents or middle adolescents. Parents of first-born children reported significantly more stress than did more experienced parents. Although mothers and fathers reported comparable levels of overall parental stress, their stress was, in part, the result of different factors. Fathers reported higher levels of stress if their children reported not following their advice and being involved in deviant activities. For mothers, stress was significantly related to their children's desire for greater autonomy. Emotional detachment was not a significant predictor of parental stress for either mothers or fathers. Implications of the findings for the parent-child relationship during adolescence are discussed.Received Ph.D. from Cornell University in 1984.

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.

This study was undertaken to examine the relative contribution of paternal history of substance abuse and difficult temperament in fathers and sons on a panel of individual, family, and interpersonal risk factors shown to be associated with deviant peer affiliations among boys. Deviant peer affiliations among boys have been associated with development of a conduct disorder and early age substance use. In a sample of sons of substance abusing fathers (n =56) and normal fathers (n=94), a structural equation path analysis revealed that the conjoint influence of paternal history of substance abuse and difficult temperament in fathers and sons influenced family and interpersonal processes that, in turn, influenced the developmental trajectory of the child toward deviant peer affiliations. The full model (F=74.49, p<.001, Stability Index=0.70) explained 50% of the variance on sons' Peer Delinquency Scale scores. Implications for primary prevention are discussed.Supported by the Center for Education and Drug Abuse Research (CEDAR), Pittsburgh, PA.

We report data from the first two years of a longitudinal study of depression, and explanatory style in children. Measures of these variables have been obtained from a group of elementary school children every six months since they were in the third grade. Results show that the boys consistently reported more depressive symptoms than the girls. This was particularly true for symptoms of anhedonia and behavioral disturbance. The boys also showed much more maladaptive explanatory styles than the girls. These results are discussed in light of previous studies of sex differences in children's attributions. Possible reasons for the expected switch in the sex differences in puberty are also discussed.Received Ph.D. from University of Pennsylvania.

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.

A family relations model for the study of adolescent egocentrism was tested in an exploratory study of the relationship between parental socialization styles and adolescents' imaginary audience behavior. A sample of adolescent boys (n=58) and girls (n=57) responded to Heilbrun's Parent-Child Interaction Rating Scale and Schaefer's Parent-Behavior Inventory and completed Elkind and Bowen's Imaginary Audience Scale. As hypothesized, rejection-control was associated with increased imaginary audience behavior, while physical affect was negatively related to self-consciousness. Sex differences were noted, with rejection-control being most important in predicting self-consciousness for boys and physical affect being the best predictor of girls' egocentrism behavior. The data provide an alternative model to a cognitive developmental perspective of adolescent egocentrism development.Research was partially supported through the Western Regional Research Project W-144, Development of Social Competency in Children, with funding in part from the Science and Education Administration/Cooperative Research of USDA, and the Utah State University Agricultural Experiment Station.Received his M.A. in psychology from the University of Nebraska at Omaha and Ph.D. in human development from the Pennsylvania State University.

This study examined the factors contributing to the self-reported use of social and overt aggression among 745 10–14-year-old European American and Latino adolescents. Hierarchical multiple regression analyses showed that dispositional social evaluative anxiety was uniquely positively associated with boys’ and girls’ social aggression and negatively associated with boys’ overt aggression. Maternal psychological control was positively associated with overt aggression for all boys, but with social aggression only for Latino boys. Although maternal psychological control also was associated with girls’ use of overt aggression, this effect was stronger among older than among younger females. The relationship between maternal psychological control and girls’ social aggression was mediated by social evaluative anxiety. Implications for elevated levels of social evaluative anxiety are discussed within a social cognitive theory perspective and for maternal psychological control within a social learning theory perspective.Received Ph.D. in Developmental Psychology from Michigan State University.

Evaluated psychosocial differences between adolescent users and nonusers of an urban school-based health clinic, considering the influence of gender. As expected, a number of gender differences were found (e.g., girls reported more fear, were rated as more likeable by peers than boys). Examination of differences based purely on clinic use indicated that nonusers were rated as more socially withdrawn by their peers than clinic users; otherwise, these two groups did not differ on psychosocial measures. Gender by clinic-status interaction effects were found for academic measures (e.g., nonusing boys had more absences and lower grades than boys who used the clinic). A group of intensive clinic users (n=14) reported higher levels of emotional distress than other students, and surprisingly, most of these students were not receiving mental health services.Received Ph.D. from Virginia Polytechnic Institute and State University in 1991.

This longitudinal study examined whether the risk and positive factors contributing to the delinquent behaviors and internalizing problems of 454 Latino adolescents varied across maternal linguistic acculturation and adolescent gender. Although the level of cumulative risk to which the 10-to-14-year old adolescents were exposed did not vary by maternal linguistic acculturation, the factors contributing to their subsequent adjustment 16 months later varied substantially. Multiple regression analyses showed that for boys, maternal monitoring offset cumulative risk effects in the high acculturation group, but was unrelated to adjustment in the low acculturation group. Social competence served a protective function for boys in the high acculturation group, but was detrimental for boys in the low acculturation group and mother-son relationship quality directly predicted more subsequent delinquent behaviors among boys in the low acculturation group. Maternal monitoring was the only positive factor contributing to girls’ adjustment, directly predicting fewer delinquent behaviors for all girls.

Explored the influence of life stress as mediated or moderated by locus of control, family environment, social support, and coping style on psychological adjustment and school performance in 164 ninth graders from Baltimore. Gender differences in findings were shown. For boys, family cohesion was the only variable found to protect against the effects of stress. Family cohesion did not serve protective functions for girls, and along with overall social support, was associated with increased vulnerability to school problems. The report of problem-focused coping strategies exerted a number of protective functions for girls only. External locus of control was found to increase boys' and girls' vulnerability to the effects of life stress.

Divergent perceptions (or disagreements) within the mother-daughter dyad and the association of such divergence with daughter's affective and behavioral well-being were examined in the current study. One hundred sixty-one mother-daughter dyads (daughters aged 14–18 years; mothers aged 37–59 years) completed paper- and-pencil measures assessing their perceptions of family cohesion and family conflict; daughters also rated their own depressive affect and dieting behavior. While the means for groups of mothers and daughters on family cohesion and conflict were similar, dyads varied substantially in their level of agreement. Disagreements on family cohesion were associated with daughter dieting behavior; maternal employment status was more highly associated with daughter depressive affect than either family conflict or cohesion. Findings are discussed in terms of their implications for studying the divergent perceptions of family members, and for family systems and relationship approaches to understanding the family.The research presented in this paper was supported by the W.

Associations between hormonal and physical status and girls' depressive affect, aggressive affect, and delinquent behavior were studied over the course of one year. Seventy-two White girls, aged 10–14 at initial data collection, were seen twice. Endocrinological status (estradiol, luteinizing hormone [LH], folicle stimulating hormone [FSH], testosterone, and dehydroepiandosterone sulfate [DHEAS] at Time 1, physical development (menarche, secondary sexual characteristics) and maturational timing at Times 1 and 2 were used to predict self- and maternal reports of depressive affect, and self-reports of aggressive affect and delinquent behavior at Time 2. It was posited that initial endocrinological status, as represented by hormonal categories derived by Warren and Brooks-Gunn [(1989) Mood and Behavior at Adolescence: Evidence for Hormonal Factors, Journal of Clinical Endocrinology and Metabolism, Vol. 69, pp. 77–83] and reflecting estradiol, LH, and FSH levels, would be associated with affective expression and delinquent behavior one year later. DHEAS, however, was not expected to be associated with affective expression a year later as it is thought to be more indicative of adrenal changes that are in part environmentally mediated. Initial affective expression was hypothesized to account for more of the variation than prior hormonal status. Hormonal categories predicted depressive and aggressive affect a year later, while DHEAS, physical status, and maturational timing did not. Initial hormonal categories were associated with subsequent reports of delinquent behavior, although not after physical status or prior reports of delinquency were entered into the regression. Initial reports of affective expression accounted for a far greater proportion of the variance in aggressive affect and delinquent behavior than did hormonal or physical status.Received Ph.D. from Institute of Child Development, University of Minnesota.

Parents' midlife concerns and the resolution of those concerns were examined as a function of their children's adolescence and their involvement in employment via analyses acknowledging the interdependence of mothers and fathers. Multivariate analyses of variance results demonstrated that fathers' and mothers' midlife concerns were similar and modestly related to their children's pubertal development. There were significant differences between families of sons and of daughters. Mothers' and fathers' temporal and emotional involvement in paid work were differentially related to their own and to one another's midlife concerns. Finally, the relationships among parents' midlife concerns, work involvement, and children's pubertal status depended in part on the degree to which spouses felt supported by one another.Portions of this paper were presented at the annual meeting of the National Council on Family Relations, New Orleans, Louisiana, November 1989.Received Ph.D. from The Pennsylvania State University. Research interests: work-family relationships, men's and women's development during midlife, and work-family issues in small businesses.Received Ph.D. from Cornell University.

Under investigation were effects of a course in sex education on a population of emotionally disturbed adolescents who were enrolled as day patients in a school program that is part of the Adolescent Treatment Program of the Institute of Pennsylvania Hospital. Pre- and posttesting of knowledge and attitudes and staff observation were used to measure changes. The results of the study indicated that patients responded age appropriately and gained knowledge and an increased openness about sexuality issues. In addition, there was no regression nor dysfunction as a result of the materials presented, and therapeutic and educational processes were not disrupted by the patients' involvement in the course. It was concluded that a sex education course is clinically and educationally useful on many levels within a therapeutic setting.Received M.S. from University of Pennsylvania.
