Timing of first sexual intercourse: the role of social control,social learning,and problem behavior

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.

Adolescent-Mother Agreement about Adolescent Problem Behaviors: Direction and Predictors of Disagreement

Correlations between adolescent and parent reports of adolescent problems are low in magnitude. In community samples adolescents tend to report more problems than parents and in clinical samples adolescents tend to report fewer problems than parents. Indices of agreement may be biased if some adolescents in a given sample report more problems and others report fewer problems than parents. In the current study, order and mean agreement between adolescent and maternal reports of adolescent internalizing and externalizing problems, taking into account the direction of disagreement, was examined in a community sample of 133 young adolescents and their mothers. Two-thirds to three-quarters of adolescents reported more problems than mothers. Accounting for the direction of discrepancies resulted in improved agreement between adolescents and mothers and differing patterns of predictors of discrepancies. Additionally, the results demonstrate the need to control for relations between adolescent-reported problems and discrepancies when exploring predictors of discrepancies. Erin T.

The relationship of father absence and antisocial behavior to social egocentrism in adolescent mexican american females

This study investigated the relationship of family structure (father absence and intact) and the level of antisocial behavior (high and low) to social egocentrism in adolescent Mexican American females. The results indicated that high antisocial females had significantly higher egocentrism scores than low antisocial females. No main effect was found for family structure. A significant interaction was found between antisocial behavior and family structure, indicating that the high antisocial-father absent group had the highest egocentrism scores among the four groups.Received her Ph.D. from the University of Southern California in 1978.

Defendant characteristics and judgment behaviors of adolescent mock jurors

Fictitious court cases involving child abuse were presented to 140 male undergraduates and 140 male junior high school students to determine if the tendency to deal harshly with alleged criminals is dependent upon certain defendant characteristics. Results indicate that younger adolescent jurors give longer sentences than older adolescent jurors, and male defendants receive longer sentences than female defendants. While no significant main effects for case content were found, younger jurors gave longer sentences and attributed more responsibility to a parent who beat his/her child, while older adolescent jurors attributed more responsibility and prescribed longer sentences to a parent who burned the child. Implications for future research with adolescent jurors are discussed.Received Ph.D. from Lehigh University, Major interests include adolescent and adult personality and social development, developmental abnormalities, and jury behavior.Received Ph.D. from Lehigh University.

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.

The relationship of observed maternal behavior to questionnaire measures of parenting knowledge,attitudes, and emotional state in adolescent mothers

Although relationships have been found between maternal psychological characteristics and cognitive and emotional outcomes in children, the behaviors which may mediate these relationships are seldom examined. This is especially true for adolescent mothers, whose children are thought to be at high risk for adverse outcomes. In this study, adolescent mothers in two special programs completed questionnaires measuring perception of the newborn (Neonatal Perception Inventory), knowledge of influences on child development (Infant Caregiving Inventory), and emotional state (General Health Questionnaire); they were also systematically observed while interacting with their infants in a naturalistic situation. Specific maternal behaviors were found to vary with the age of the mother and of the baby. Mothers with neutral or negative perceptions of their infants touched them less than did mothers with positive perceptions. Degree of emotional disturbance was inversely related to the amount of time that the mother looked at her infant while in physical contact.This research was supported in part by NIH Biomedical Research Support Grant No. BRS 507 RR 05445-19 to Johns Hopkins University School of Hygiene and Public Health.Received her Sc.D. in mental hygiene (comparative behavior) from Johns Hopkins University.

Moral development and discipline encounter in delinquent and nondelinquent adolescents

The present study tested whether Hoffman's conceptualization of the relationship between disciplinary techniques and moral development can account for findings that delinquents score lower than nondelinquents on various measures of moral development. Twenty-six delinquent adolescents, 20 middle class nondelinquents, and 20 lower class non-delinquents were assessed on moral development using the following measures: resistance to temptation, moral stage, feelings after offense, judgment about the severity of punishment, and confession. The use of induction by parents was examined with a Q-sort administered to adolescents and their parents. On most measures of moral development delinquents performed lower than nondelinquents. Less induction was found to be used with delinquents than with nondelinquents. Induction was positively related to most moral measures. It was concluded that disciplinary methods may account for differential moral development of delinquent versus nondelinquent adolescents.This research was supported by grant No. 10/B-6 from the Ford Foundation—Israel Foundation Trustees and the School of Social Work Research Committee, University of Haifa.Received Ph.D. from the University of Minnesota in 1977.

Mediators of depression among low-income,adolescent mothers of infants: A longitudinal perspective

The purpose of this study was to identify, using a life events perspective, Stressors and resources that mediate depression for adolescent mothers at the time of the birth of their child and at one year postpartum. The data for this study consisted of interviews with 157 low-income adolescent mothers age 12–18 at the birth of their child. They were selected from a larger prospective study of mothers of infants and stress. Multiple regression analyses revealed two key results that were consistent for the data obtained at birth and at one year postpartum. Predictors of depressive symptomatology and of a clinical syndrome of depression were similar. Also, Stressors generally were more important as mediators of depression than resources.Received Ph.D. in child and family studies from the University of Tennessee.

Adolescents' Participation in Service Activities and Its Impact on Academic,Behavioral, and Civic Outcomes

The National Household Education Survey, a nationally representative data set (N=4,306 high school students and one parent of each), was analyzed to describe characteristics of adolescents, the nature of their service activities, and academic, behavioral and civic outcomes associated with service (voluntary compared to school-required and by type of service). Participation in any service is associated with positive outcomes whether service is voluntary or required. Adolescents who worked directly with individuals in need had better academic adjustment; those who worked for organizations had better civic outcomes than adolescents who performed other types of service. Findings are discussed in terms of their significance for adolescent development, educational policy, and the use of large national data sets to examine service participation.

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).

Adolescent women's developing identity: A study of self-definition in the context of family relationships

This study generated adolescent women's perception of their identity in relation to family members spanning three generations and related these perceived relationships to their sex-role orientation. Subjects were 20 firstborn university women from intact families. The methodology used multiple sources of information, including open-ended interviewing procedures, rating scales, and standard research measures of sex-role identity. Significantly more constructs empirically differentiated family by generation than by sex. Congruence of young women with both the parent and grandparent generation, relative number of masculine stereotypes produced, and personality traits of males and females were significantly influenced by the presence of a brother in the sibling generation. There was no relationship between family constellation and sex-role orientation. Feminine women were significantly more congruent with other females in their family than androgynous women. There was a linear trend for androgynous women to be increasingly individuated across the generations.Received her Ph.D. from Yale University.

Comparison of adolescents' perceptions and behaviors in single- and two-parent families

This study investigated the self-concepts, school achievement, occupational aspirations, vocational maturity, and perceptions of parents of children from two-parent and single-parent homes. The sample contained 559 children, 19% from single-parent homes. A multivariateF indicated children from two-parent homes had significantly higher school grades and occupational aspirations. There were also significant differences in children's perceptions of relationships with fathers, but not with mothers. It was argued that family structure has an impact on adolescents' perceptions and behaviors.Received his Ph.D. from the State University of New York at Buffalo.

Sex differences in intellectual and ego development in late adolescence

Perry's scheme of intellectual and ethical development was examined for sex differences with respect to areas of identity concern for which sex differences have been suggested: occupational choice, interpersonal relationships, and sexual identity. The content area of religion and ego development, as measured by Loevinger's sentence completion test (SCT), were also examined. Thirty-one females and 29 males participated. An interview format which applied Perry's unstructured approach to each of the four areas was utilized. Transcribed interviews and SCTs were rated blind. Structural as well as content analyses were performed. Structural analyses revealed no significant sex differences overall or by content area. However, multiple and stepwise regression analyses revealed patterns in which male personality processes consistently focused upon occupational issues while female processes focused upon interpersonal and sexual issues. Ego development was found to be highly correlated with intellectual development for men but unrelated for women. Content analyses suggest that women focus their interpersonal worlds developmentally upon issues of trust while men focus upon issues of rightness. Results are interpreted in the context of recent works by Gilligan concerning sex differences in development.Completing his Ph.D. in clinical psychology at Miami University.

From trust on intimacy: A new inventory for examining erikson's stages of psychosocial development

A new inventory for examining the first six of Erikson's psychosocial stages is described. The self-report questionnaire, developed in a pilot study of 97 adolescents and tested in a study of 622 adolescents, has 12 items for each subscale. Measures of reliability and validity are reported. It is concluded that the Erikson Psychosocial Stage Inventory (EPSI) is a useful measure for researchers interested in development from early adolescence and in mapping changes as a function of life events.This research was supported by a grant from the Education Research and Development Committee.Received Ph.D. from University of Melbourne.

Teen pregnancy in New Orleans: Factors that differentiate teens who deliver,abort, and successfully contracept

This study reports findings from interviews with three groups of black teenagers: child bearers (n=136), terminators (n=92), and contraceptors (never been pregnant,n=151). The focus of this research is to describe the differences between these three groups of teenagers in an attempt to identify factors that may best differentiate the groups. The findings suggest that, among the teens who became pregnant, motivation to use contraceptives may be the key factor. More than 86% of these teens knew about contraceptives at the time they became pregnant and nearly three-quarters knew where to obtain contraceptives. However, only 16% of teens who became pregnant reported to be using a contraceptive at the time they became pregnant. Education about the availability and mode of contraceptive use is essential.Funding was provided by the Research Council, Tulane University, New Orleans, Louisiana.Received her MPH from Tulane School of Public Health.

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.

Parents' and teachers' beliefs about adolescents: Effects of sex and experience

Three studies examine beliefs that parents and teachers have about adolescents. A distinction is made between category-based beliefs (concerning adolescents as a group) and target-based beliefs (concerning individual adoles cents). In Study 1, 90 late elementary and junior high school teachers indicated degree of agreement with a set of category-based statements about adolescents. Parents of early adolescents in Study 2 (N=1272) responded to category- and target-based statements. Study 3 compares the responses of teachers in Study 1 and parents in Study 2. Both teachers and parents endorsed beliefs that adolescence is difficult, and that adults can have an impact. Compared to fathers, mothers believed more in difficulty and in the negative effects of biological change on behavior. Parents of daughters believed adolescence is more difficult than parents of sons. Among teachers, amount of experience with adolescents was positively associated with the belief that adolescence is a difficult period of life. For parents, the effect of amount of experience was mixed. Experience had a greater impact on the category-based beliefs of teachers than parents. Possible influences on the origins and modification of beliefs are discussed.Received Ph.D. in psychology from The University of Michigan.

School return among pregnant adolescents

School return by adolescent mothers has been problematic. Many of the barriers to continuing education have been created by school system practices and policies. Recent administrative and court decisions are forcing changes in these traditional practices. Participants in an adolescent pregnancy program were permitted to attend their usual high school during and after pregnancy. Staff members discussed this and other educational opportunities with each eligible student and her family. More members of the program than control group reported some school attendance during the quarter of the delivery. Compared with the control group, which was permitted but not systematically encouraged to return, more program participants returned to day school following the pregnancy. Unexpectedly high rates of return to other school programs (other than day school) were reported by members of the control group. It is argued that the program effects are primarily a function of elimination of school system barriers, both formal and informal, to school return so that the subjects' already high motivation to return could be realized.Received her Ph.D. in sociology from the University of Washington.

Death fantasies of father-absent and father-present late adolescents

Parental perceptions of father-absent and father-present late adolescents were studied by having them create stories to selected pictures from the Thematic Apperception Test and the Michigan Pictures Test. Ratings on the manifest thematic content of the stories revealed that father-present females, but not males, introduced themes of death and loss involving the parents with significantly greater frequency than did late adolescents who had actually lost their fathers. One of the tasks of adolescence, as described in psychoanalytic writings, is decathecting internalized parental images. It is possible that father-present females produced significantly more death and loss themes because they were actively coping with their fantasies of parental loss. The significantly fewer fantasies of parental loss given by father-absent females is consistent with this psychoanalytic model which suggests that the loss of a parent at an earlier developmental period complicates the decathexis process in adolescence. Reasons for the failure to find differences between father-absent and father-present males are discussed, and suggestions for future research are provided.This research is based upon the doctoral dissertation of the first author.Received his Ph.D. in clinical psychology from the University of Texas at Austin; internship at the Children's Hospital Medical Center, Boston, Massachusetts.

Urban youth under stress: Empirical identification of protective factors

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.
