Longitudinal data from the «Berlin-Bremen Study on Health Behavior» are used to investigate smoking transitions between different stages of smoking. 1357 seventh and eighth graders were asked about their smoking behavior, their expectations with regard to smoking, smoking in their environment, and their self-image in Fall, 1983. 86% and 81% participated again one and two years later, respectively. Analyses of carbon monoxide and serum thiocyanate levels revealed adequate validity for self-reported smoking behavior. Rates of smoking were dramatically different for different educational strata. Direct and indirect functions of smoking are distinguished. The «indirect» function refers to smoking as a means of obtaining access to peer groups, thus increasing one’s psychological well-being. Direct functions refer to social and affective effects of smoking such as looking older or calming down. In line with expectations, indirect functions were found to be more important for younger adolescents and for smoking onset. In contrast, direct functions were better predictors of the smoking behavior of older adolescents and of the transition to regular smoking.  相似文献

OBJECTIVE: We investigated the possible reciprocal relationship between victimization experiences and psychological functioning by assessing abuse experiences in childhood, adolescence, and during a 2-month follow-up period. METHOD: At the beginning of the study (Time 1), abuse histories, trauma and depressive symptoms, and interpersonal functioning were assessed in 551 college women. Subsequent victimization experiences and psychological outcomes were assessed at the follow-up (Time 2). RESULTS: Path analyses indicated that verbal abuse by the mother and father were predictive of various psychological outcomes as measured at Time 1 and emerged as the only significant predictors of adolescent dating violence. Adolescent dating violence subsequently predicted the experience of dating violence during the 2-month follow-up period. Paternal physical abuse predicted adolescent sexual victimization which subsequently predicted all symptom measures at Time 1. Conversely, the experience of adolescent physical dating violence was not predictive of any of the symptom measures at Time 1. For those women who experienced dating violence during the follow-up, however, the severity of their abusive experiences was related to both depression and interpersonal problems assessed at Time 2. In comparison, for those women who experienced sexual victimization during the follow-up period, the severity of their abusive experiences was related to trauma symptoms. Interpersonal problems emerged as both an aftereffect of adolescent sexual victimization experience and a predictor of a subsequent sexual victimization experience during the follow-up. CONCLUSIONS: Given that emotional abuse emerged as a predictor of adolescent dating violence and psychological outcomes, researchers and clinicians need to continue to explore this problem. Further, it is important to assess how interpersonal problems contribute to the risk of subsequent sexual victimization and to try to break the cycle between adolescent abuse experiences and subsequent physical and sexual assaults.  相似文献

The aim of this explorative study was to develop and test a pedagogy aimed at promoting students’ ability to perform historical contextualization. Teaching historical contextualization was conceptualized in terms of four pedagogical design principles: (1) making students aware of the consequences of a present-oriented perspective when examining the past, (2) enhancing the reconstruction of a historical context, (3) enhancing the use of the historical context to explain historical phenomena and (4) enhancing historical empathy. The effectiveness of these principles was explored in a lesson unit focusing on the seventeenth and eighteenth centuries. In a quasi-experimental pre-test–post-test design with experimental and control conditions, the effects of the pedagogy on 15- and 16-year-old students’ ability to perform historical contextualization were examined (n = 131). The results indicated that students in the experimental condition significantly improved their ability to perform historical contextualization compared to students in the control condition. These findings could be used to help teachers and other educational professionals design and implement historical contextualization tasks and instructions.  相似文献

Inappropriate, aggressive and disruptive behaviour in the classroom can be detrimental to child and teacher well-being. This study involved a longer-term evaluation of the Incredible Years Teacher [Classroom Management] programme (IYTP) undertaken mainly within disadvantaged schools in south-west Ireland. The IYTP is designed to strengthen teacher classroom management competencies. Eleven teachers, who had previously participated in a group-randomised control trial (RCT), took part in a 12-month post-baseline follow-up assessment. Psychometric and observational measures were administered to assess teachers when interacting with children (n?=?217) in their classes. Qualitative data were collected from a sub-sample of teachers to explore their perceptions of programme impact and utility. The quantitative results showed some significant improvements in teachers’ classroom management, although few changes were recorded on teacher-child observation measures. Qualitative findings indicated continued implementation of proactive disciplining strategies and higher levels of teacher self-efficacy. These results suggest, albeit tentatively in view of the study limitations, that the IYTP can benefit teacher classroom management, as well as teacher well-being, particularly within disadvantaged schools where behavioural problems tend to be more prevalent. The IYTP could prove useful in improving teacher competencies and the classroom environment in the longer term, although a need for further research is indicated.  相似文献

Interviews were conducted with 336 mother-child dyads (children's ages ranged from 6 to 17 years; mothers' ages ranged from 20 to 59 years) in China, India, Italy, Kenya, the Philippines, and Thailand to examine whether normativeness of physical discipline moderates the link between mothers' use of physical discipline and children's adjustment. Multilevel regression analyses revealed that physical discipline was less strongly associated with adverse child outcomes in conditions of greater perceived normativeness, but physical discipline was also associated with more adverse outcomes regardless of its perceived normativeness. Countries with the lowest use of physical discipline showed the strongest association between mothers' use and children's behavior problems, but in all countries higher use of physical discipline was associated with more aggression and anxiety.  相似文献

The role parents can play in supporting early reading attainment is well documented. There is still, however, a need to understand what motivates parents to become involved in reading at home with their child. Past research, based upon correlational studies, has mixed findings regarding the influence of the teacher and the child on parents’ motivation at home. Through two quasi-experiments, the present study explored the influence of teacher invitations in Kindergarten classes, and child invitations in Grade 2 classes on completion rates of a home reading challenge. The completion of the home reading among families was investigated across two metropolitan schools in Sydney, Australia. Both of the interventions resulted in significantly higher completion rates compared to control groups (teacher invitations: d = .68; child invitations: d = .73). This paper adds to existing research by providing a clearer picture of the cause-and-effect relationship between schools’ use of invitations to facilitate children’s home reading.  相似文献

The only Chinese person who worked in my office was Gillian Tang. She had come to London from south China to complete her education and this was her first job. To us westerners she was a most unusual person. She was kind to everyone, and never suspected that anyone might abuse her kindness. She was the sort of person who, if she heard any of us talking about a book or a video or something else which we wanted to borrow or buy, she  相似文献
