Validity of self-report measures of girls' pubertal status 总被引：10，自引：1，他引：10
To understand the meaning of somatic changes to the adolescent and their possible effects on behavior, developmentalists have begun to examine maturational timing and status in detail. Efforts have been hampered by the necessity of obtaining somatic growth data by physician examination. In the present study, 3 self-report methods for rating secondary sexual characteristic growth were compared to physician ratings; the accuracy of self-reported height and weight also was assessed. Specifically, 151 11-, 12-, and 13-year-old girls rated their breast and pubic hair development using schematics of the 5 Tanner stages and filled out the Pubertal Development Scale (PDS); their mothers also rated their daughters' development using the Tanner stage schematics. The correlation with physician Tanner ratings was .82 for self-ratings, .85 for ratings by the mother, and between .61 and .67 for self-reports on the PDS. The correlations for self- and actual reports of weight and height were .98 and .75, respectively. The usefulness of the PDS, Tanner ratings, and self-reported height and weight as adequate estimates of pubertal development is discussed. 相似文献

Marriage, adult adjustment, and early parenting 总被引：3，自引：0，他引：3
The impact of parents' marriages, measured prenatally, on their parenting of firstborn, 3-month-old infants was assessed. Though the association between marriage and parenting was the focus, adult psychological adjustment was measured also to rule out the alternative hypothesis that psychological adjustment relates to both marital quality and parenting quality and accounts for any association between them. Hierarchical multiple regression analyses in which parental adjustment was entered first as a covariate were used to test the relation between close/confiding marriages and parenting of 3-month-old infants. From the findings, it was concluded that even when differences in individual psychological adjustment are taken into account, mothers are warmer and more sensitive with their infants and fathers hold more positive attitudes toward their infants and their roles as parents when they are in close/confiding marriages. It is asserted that qualities of marriage play an important part in the development of parent-child relationships. 相似文献

The Antecedents of Menarcheal Age: Heredity, Family Environment, and Stressful Life Events 总被引：5，自引：0，他引：5
Variations in pubertal timing, specifically age at menarche, have been associated with several antecedents, both genetic and environmental. Recent research has considered a broader range of environmental stressors and their influence on the development of the reproductive system. In this investigation, the following possible antecedents were considered: ( a ) hereditary transmission, ( b ) weight and weight for height, ( c ) stressful life events, ( d ) family relations, ( e ) absence or presence of an adult male in the household, and ( f ) psychological adjustment. Subjects were 75 premenarcheal girls between the ages of 10 and 14 drawn from a larger longitudinal investigation of adolescent development. Girls were from white, well-educated, middle- to upper-middle-class families and attended private schools in a northeastern urban area. While breast development, weight, family relations, and depressive affect were predictive of age at menarche, family relations predicted age at menarche above the influence of breast development or weight. A trend for maternal age at menarche to predict adolescent's age at menarche was found. Weight for height, presence of an adult male in the household, and stressful events were not predictive of age at menarche. These complex interactions of biological and psychosocial development demonstrated here may account to some extent for the inter- and intraindividual variation observed in pubertal development. 相似文献

Nearly one quarter of international graduate students in the USA and Canada are accompanied by their spouse, typically highly educated, professional women. Because they are not students, accompanying spouses’ distinctive needs and experiences are often invisible. This article focuses on an overlooked population of adult learners: accompanying spouses who enrol in English as a Second Language (ESL) courses. Qualitative data are used to explore the social integration and adjustment of 13 accompanying spouses who attended an ESL class in State College, Pennsylvania, a rural university town in the USA. Specifically, we examine how accompanying spouses described their social integration and changes in roles and identities, how perceptions of sacrifice for their partner related to their adjustment experiences, how they gained entrée and navigated social spaces in the host community and what they believe enhanced and hindered their adjustment and social integration. Accompanying spouses portrayed themselves as initiators who created meaningful experiences by locating and taking advantage of opportunities and resources, including language and culture classes, to forge new identities and structure their lives. The findings can inform the design, development and dissemination of adult education and support services for accompanying spouses, especially in geographically isolated areas. 相似文献

Standard treatment options for breast cancer include surgery, chemotherapy, radiation, and targeted therapies, such as adjuvant hormonal therapy and monoclonal antibodies. Recently, the recognition that chronic inflammation in the tumor microenvironment promotes tumor growth and survival during different stages of breast cancer development has led to the development of novel immunotherapies. Several immunotherapeutic strategies have been studied both preclinically and clinically and already have been shown to enhance the efficacy of conven- tional treatment modalities. Therefore, therapies targeting the immune system may represent a promising next-generation approach for the treatment of breast cancers. This review will discuss recent findings that elucidate the roles of suppressive immune cells and proinflammatory cytokines and chemokines in the tumor-promoting microen- vironment, and the most current immunotherapeutic strategies in breast cancer. 相似文献

A sample of 141 predominately working class middle age (X = 53.03 years; SD = 6.92) and young adult (X = 21.34 years; SD = 3.65) university students responded to a survey instrument that assessed motives for enrolling in university classes and reactions to instructional strategies commonly used in the classroom. Results indicated that middle age and younger students’ motives for enrolling in university classes were intrinsic in nature and based on needs for intellectual growth and self‐development. In addition, findings revealed that younger students viewed learning life adjustment skills as a more powerful motivator for pursuing advanced education than did middle age students (p < .01). Both age groups of students were found to have similar attitudes about the effectiveness of teaching techniques presently used in the university classroom. Middle age and younger students reported positive reactions to the use of hands‐on‐experiences, lectures with discussions, and the lecture‐only format and negative reactions to the use of student presentations and role playing. It was concluded that the findings of this study supported the design of age‐integrated university programs and suggested that much of the present curricula satisfies the educational goals and needs of middle age and younger students. 相似文献

The over-time reciprocal links between parenting and adolescent adjustment were examined in a sample of 1,354 serious adolescent offenders followed for 3 years (16 years of age at baseline, SD = 1.14). Parallel processing growth curve models provided independent estimates of the impact of parenting on adolescent functioning as well as the impact of adolescent functioning on parenting. Positive adolescent development was facilitated by high parental warmth and low parental hostility. Parental monitoring predicted less problematic behavior, but less positive functioning as well. Predictably, parents became warmer and less hostile in response to positive adolescent development, and less warm in response to problematic adolescent functioning. Parental monitoring declined when adolescents exhibited either positive or problematic functioning. 相似文献

Social Competence in the School Setting: Prospective Cross-Domain Associations among Inner-City Teens 总被引：3，自引：0，他引：3

In this 6-month prospective study of 138 ninth-grade inner-city students, associations among different aspects of school-based social competence were examined. In addition, links between initial emotional adjustment and subsequent social competence at school were explored. Aspects of social competence examined included academic achievement, peer reputation, and teacher-rated classroom behaviors. Emotional adjustment was measured based on self-reported internalizing and externalizing symptoms. Consonant with views positing continuity and coherence of development, high temporal consistency was found within each social competence domain. In addition, superior adjustment in one domain was sometimes associated with subsequent improvements in other spheres as well. Exceptions found to this pattern were that ( a ) both as an antecedent and as a consequent variable, peer-rated sociability was negatively linked with other indices of school-based functioning, and ( b ) among girls, high anxiety was related to improved performance at school over the year. Ecological influences in adolescent adjustment are discussed, and implications of the findings for future research are explored. 相似文献

A 3‐month intergenerational program was developed on the premise that it is important for young adults, who are in the formative period of career development and direction, to experience the benefits of positive interaction with older persons. Program evaluation findings showed that participation not only influenced the young adults’ interest in gerontology, but also increased their willingness to accept older persons on social and academic levels. Positive changes were documented for the Senior Guest students and included more favorable attitudes toward young adult family members as well as toward the younger generation of college students in general. 相似文献

The purpose of this analysis was to estimate the frequency and severity of child abuse committed by adolescents who were in nonparental caregiving roles. The sample was composed of cases in which either physical or sexual abuse was substantiated through child welfare investigation. The main comparisons were between adolescent and adult caregivers. While caregiver age did not appear to have a consistent effect on the occurrence of physical abuse, notable differences between adolescents and adults were found in the area of sexual abuse. Not only were adolescents observed to commit substantially more sexual abuse than older caregiver cohorts, but the sexual abuse they committed was more likely to involve intercourse and physical assault. These findings have implications for future research and practice. 相似文献

Deafness is more than a medical condition. Recent theories have emphasized the importance of environmental factors on the psychosocial development of deaf children. As part of a larger scale study, this article aims to investigate the impact of the following variables on deaf students' psychosocial adjustment in Turkey: student-related background and experiential characteristics, parent-related variables, school-related factors, and teacher-related variables. The sample of 1,097 deaf students enrolled in the elementary, secondary, and high schools was drawn from 34 schools in 24 cities on a national geographical spread. The multiple regression analysis revealed that degree of hearing loss, additional handicap, and age at onset of deafness were negatively related to psychosocial adjustment of deaf students. However, there was a positive relationship between psychosocial variables and some of the independent variables, such as use of hearing aids, speech intelligibility, academic achievement, parental hearing status, and communication methods used at school. The findings of the study do not support a "pathological" view of deafness, suggesting that it was not deafness per se but that some environmental factors were also influential on the psychosocial adjustment of deaf students. 相似文献

This article analyses the intellectual discourses of adult development and adult learning. It argues that through a process of transformative adult learning individuals can experience the disintegration and reintegration of past and present human growth. The development of adults is considered not in terms of discrete theories but as a collage of theories. The writers analyse and interpret the literature that attempts to study the interaction of individuals in the total context of the inner and outer forces that impinge on their life. We conclude from a study of the literature that adult development, from a transformative perspective, is more than adjustment to a particular society; it is a qualitative change in how one views the world; it involves tension and struggle that are productive of a new consciousness. This change occurs through a dialectical process that calls for movement through the old style of meaning‐making to a reconstruction of meaning that is a synthesis of the old and the new. It is also concluded that adult learning can foster critical awareness and critical consciousness that can effect a transformation in the way adults see themselves and others. The route to transformative adult development and transformative learning lies in acknowledging contradictions and differences and working through them, as opposed to ignoring or circumventing them. 相似文献

This is a study of early picture book comprehension, its determinants and later development through primary school. More specifically, picture book comprehension was analyzed longitudinally from age 5 to age 9, delineating the unique contributions of vocabulary, metacognitive knowledge and task orientation to the initial level as well as to the growth of comprehension. A total of 90 Finnish-speaking children participated in the study. The children’s narrative picture book comprehension was assessed at age 5, age 6 and age 9. Vocabulary, metacognitive knowledge and task orientation were evaluated at age 5. Latent growth curve modeling showed a pattern of decreasing achievement gaps in narrative picture book comprehension. Vocabulary and metacognitive knowledge uniquely contributed to the concurrent level of narrative picture book comprehension. The results further showed that metacognitive knowledge and task orientation were positive and statistically significant predictors of the growth of picture book comprehension over and above the initial level of narrative picture book comprehension. These findings add to our knowledge about the development of inter-individual differences in narrative picture book comprehension and the roles of vocabulary, metacognitive knowledge and task orientation in it. They also suggest a novel way to assess the narrative comprehension potential among students with compromised working memory or decoding ability.

Supportive parenting, Ecological Context, and Children's Adjustment: A seven-Year Longitudianl Study
Two major questions regarding the possible impact of early supportive parenting (SP) on children's school adjustment were addressed:(1) Does SP assessed prekindergarten predict grade 6 adjustment after controlling for early barsh parenting (HP)? (2) Does SP moderate (buffer) the impact of early family adversity on grade 6 adjustment? Parenting and family adversity data were drawn from home-visit interviews with 585 mothers conducted prekindergarten. Four SP measure were derived: mother-to-child warmth, proactive teaching, inductive discipline, and positive involvement. HP was indexed as the use of harsh, physical disciple. Family adversity indicators were socioeconomic disadvantage, family stress, and single parenthood. Children 's adjustment (behavior problems, social skills, and academic performance) in kindergarten and grade 6 was assessedvia teacher ratings and school records. SP predicted adjustment in grade 6, even after controlling for kindergarten adjustment and HP. High levels of SP mitigated the effects of family adversity on later behavior problems. These findings implicate both direct (main effect)and indirect (moderator of adversity) processes in the linkage between positive and supportive aspects of parenting and children's school adjustment. 相似文献

Although it is often assumed that men have an important influence on their children’s development, the supportive evidence can be difficult to locate and summarize. In this paper, we analyse the evidence with respect to four emergent themes. First, men often appear to interact with their children less sensitively than mothers do, and many children thus appear to form closer attachments to their mothers than to their fathers. Second, the data also indicate that fathers may play specific and important roles, with men in some cultures having clearly defined roles as playmates to their children. Third, paternal play styles predict later socio-emotional development while paternal involvement seems to predict adult adjustment better than maternal involvement does. Such evidence suggests, fourth, that we need appropriate measures of fatherhood that are not simply borrowed from the study of motherhood. 相似文献

This study examined narcissistic vulnerability and shame-proneness as potential mediators between childhood physical abuse (CPA) and adult anger and aggression. Participants were 400 undergraduate students, 134 of whom had a history of CPA. All participants completed self-report questionnaires assessing history of CPA, shame-proneness, narcissistic vulnerability, physical aggression, trait anger, and hostility. Results indicated abused participants were more angry and aggressive and experienced higher levels of shame-proneness and narcissistic vulnerability than nonabused participants. Multiple mediation analyses showed that narcissistic vulnerability, but not shame-proneness, partially mediated the relation between abuse and physical aggression. However, narcissistic vulnerability and shame-proneness both emerged as partial mediators between abuse and the anger and hostility variables. These findings suggest that narcissistic vulnerability and shame-proneness may function as mediators of adjustment following childhood maltreatment. Study limitations and recommendations for future research are discussed. 相似文献

Adult attachment, parent emotion, and observed parenting behavior: mediator and moderator models 总被引：1，自引：0，他引：1
In a middle-class sample of mothers of 2-year-olds, adult attachment classifications measured in the Adult Attachment Interview (AAI) were related to maternal self-reported emotional well-being and observed parenting behavior, and the potential mediating and moderating roles of maternal emotion were tested. Mothers classified as dismissing on the AAI reported significantly lower levels of positive affectivity. Mothers classified as preoccupied reported significantly higher levels of negative affectivity and anxiety. Preoccupied mothers were observed to be significantly higher on angry/intrusive parenting, but this association was not mediated by attachment-related differences in maternal emotion. Maternal emotional well-being did, however, moderate the associations between adult attachment and parenting behavior: Dismissing attachment was significantly associated with lower warmth/responsiveness only among mothers with higher levels of depressive symptoms. 相似文献

Research Findings: Pretend play is an essential part of child development and adjustment. However, parents, teachers, and researchers debate the function of aggression in pretend play. Different models of aggression predict that the expression of aggression in play could either increase or decrease actual aggressive behavior. The current study examined pretend play and classroom behavior in preschoolers. Children (N = 59) were administered a measure of pretend play, and teacher ratings of classroom behavior were obtained. Pretend play skills were positively associated with prosocial behavior in the classroom and negatively associated with physical aggression in the classroom. In particular, expression of oral aggression in play related to less physical aggression and more prosocial behavior in the classroom. Practice or Policy: These findings suggest that pretend play should be encouraged, as these skills relate to positive behaviors in the classroom. In addition, it was found that aggression in pretend play was not an indicator of actual aggressive behavior, as it related to positive behaviors in the classroom. Implications for parents and teachers are discussed. 相似文献
