This study investigated high school students’ process of choosing a study in higher education, using a longitudinal design. A sample of 535 adolescents participated at the beginning, middle, and end of Grade 12. Latent curve modeling revealed evidence for a mean developmental increase in the career decisional tasks of orientation, exploration, decisional status, and commitment. In general, the growth trajectories were in line with theoretical models in which orientation and broad exploration are important at the beginning of the career decision-making process whereas in-depth exploration and decisional status are considered important later on. Furthermore, the results showed substantial variability between adolescents in their initial levels of career decisional tasks and in the rate of change. Finally, growth in orientation related to growth in environmental and self-exploration, and growth in environmental exploration related to progress in commitment and decisional status.  相似文献

The present study examined (a) the predictive effect of disruptive boys' attendance to a prevention program (i.e., dosage) on post-intervention academic achievement and behavior and (b) the potential moderating effects of child and family characteristics in this context. The 3-year intervention program included reading, self-regulation, and social skills training for the boys, parental support and skills training for parents, and teacher support. A multiple-screening procedure selected 58 disruptive, low socioeconomic status boys at the age of 6 years for program participation. Multiple regression analyses and logistic regression analyses showed that the number of program sessions attended did not contribute to the prediction of boys' post-intervention disruptive behavior. However, the number of attended sessions was positively related to boys' post-intervention likability, as well as to their post-intervention writing, reading, math, and human science performances. Interaction terms revealed that family constellation moderated the link between program dosage and likability and math success, respectively, whereas boys' IQ moderated the links between dosage and boys' success in writing and math. The discussion stresses the importance of dosage-effect analysis and the examination of moderating variables in this context.  相似文献

This article presents a review of studies that have investigated the neuropsychological effects of antiretroviral treatment (ART) for HIV-1 infection. It provides a brief overview of the era of monotherapy, dual-therapy, and an extended overview of the current era of combination antiretroviral therapy (CART). This review highlights that while CART has had a dramatic effect on the incidence and the severity of HIV-associated neurocognitive disorders (HAND), HAND, in its mild form, still remains prevalent. New causes of this sustained prevalence are poor CNS penetration of some antiretroviral agents, drug resistance, poor adherence, potential neurotoxicity, co-morbidities such as the long-term CART side effects in relation to cardio-vascular disease, and chronic HIV brain infection that may facilitate the expression of new forms of neurodegenerative processes. The review emphasizes the need to address methodological limitations of published studies and the need for large and representative cross-disciplinary longitudinal investigations across the HIV illness span.  相似文献

The arithmetical performance of typically achieving 5- to 7-year-olds (N = 29) was measured at four 6-month intervals. The same seven tasks were used at each time point: exact calculation, story problems, approximate arithmetic, place value, calculation principles, forced retrieval, and written problems. Although group analysis showed mostly linear growth over the 18-month period, analysis of individual differences revealed a much more complex picture. Some children exhibited marked variation in performance across the seven tasks, including evidence of difficulty in some cases. Individual growth patterns also showed differences in developmental trajectories between children on each task and within children across tasks. The findings support the idea of the componential nature of arithmetical ability and underscore the need for further longitudinal research on typically achieving children and of careful consideration of individual differences.  相似文献

We used data from a large, longitudinal study of children in the community, the NICHD Study of Early Child Care and Youth Development, to examine how well earlier measures of delay capacity, inhibitory control, planning, and attention predicted symptoms of attention deficit hyperactivity disorder (ADHD) assessed in third grade. Children with elevated symptoms of both inattention and hyperactivity-impulsivity (n = 57) and with inattentive symptoms only (n = 80) were identified via mother and teacher reports using the “or” rule, as were children without significant symptoms (n = 790). Multinomial logistic regression analyses indicated that poorer performance on earlier measures of resistance to temptation, delay of gratification, response inhibition, attention, and planning obtained from 36 months to 1st grade predicted membership in the two symptom groups relative to the comparison group in 3rd grade, albeit with somewhat different patterns of predictors. Controls for 36 month school readiness and externalizing symptoms indicated that these results were generally robust and not an artifact of initial cognitive or behavioral differences. Implications for developmental models of ADHD are discussed.

The current article presents an analysis of the life stories of three generations of women within a family headed by a Holocaust survivor. Its uniqueness lies in its double analysis of the stories told by these women, with an interval of 12 years between telling. The first series of interviews were conducted in the early 1990s within the framework of a pioneering study in which, for the first time, three generations in each of 20 families were interviewed and their narratives analyzed. The current analyses are based on the perspective that, through life narratives, it is possible to view the transformations of relationships over time and that these transformations in relationships are central to personal development. We will examine the relationships of the women in these three generations, both with significant others and with each other. We will trace processes of development and changes in these relationships over the 12 years. Finally, we will discuss the social and methodological implications of our study.  相似文献

The current study was designed to evaluate the role of sociocultural influences over a 16 month period on strategies to lose weight, extreme weight loss strategies, and strategies to increase muscles among adolescent boys (n=344) and girls (n=246). All participants completed measures of body dissatisfaction, body image importance, strategies to lose weight, extreme weight loss strategies, and strategies to increase muscles. Measures of perceived pressure to lose weight or increase muscles from mother, father, best male friend, best female friend and the media were also evaluated. Data were gathered on three occasions, 8 months apart. The results demonstrated that boys showed a decrease in strategies to lose weight and increase muscles over time, whereas girls showed an increase. Both boys and girls showed an increase in extreme weight loss strategies with girls demonstrating a greater increase than boys. The sociocultural influences generally were perceived by girls to relate to messages to lose weight, whereas for boys they were perceived to relate to increasing muscles. Messages from parents, particularly fathers, were strong predictors of both strategies to lose weight and increase muscles among boys, with the media and best male friend playing a limited role. For girls, the strongest influences were mothers and best female friends, with few influences from fathers or the media. The results of this study are discussed in terms of the importance of the various sociocultural influences in shaping body change strategies among young adolescent boys and girls, and the implications of these findings for intervention programs for adolescents.  相似文献

ObjectivesObtaining education is an important milestone in athletes’ preparation for their professional career after sport. Literature indicates that combining school and sport is not an easy task for many aspiring youth athletes. It has been proposed that career adaptability, which refers to psychosocial resources enabling individuals to solve complex occupational transitions, present and anticipated vocational development tasks, and career related challenges could be a relevant concept for applied work with student-athletes. In this study, we examined whether there are distinct developmental profiles of career adaptability among adolescent athletes across the upper secondary school years. We also investigated the associations between career adaptability and sport withdrawal and academic achievement.Design and methodsA total of 391 Finnish-speaking student-athletes completed the questionnaire on career adaptability (Career Adapt-Abilities Scale – Dual Career Form; Ryba & Aunola, 2015; Ryba et al., 2017) at the beginning and end of upper secondary school. The participants’ background information about their sport participation and grade point average were collected upon completion of each grade of upper secondary school. The data were analysed using cluster analysis, cross-tabulation, and one-way analysis of variance.ResultsFour distinct adaptability profiles were identified: higher adaptability, lower adaptability, increasing adaptability, and decreasing adaptability. Higher and lower adaptability profiles showed stable levels of adaptability across time, whereas the adaptability level either increased or decreased in the other two profiles. Student-athletes with a lower career adaptability profile were overrepresented among those who withdrew from competitive sports, and they reported lower grade point averages than those with higher scores of career adaptability.ConclusionsHigh scores of career adaptability were associated with high grades, whereas low scores of career adaptability were associated with low grades and a probability to withdraw from competitive sport. Therefore, it is recommended that career adaptability be considered as important self-regulation resources for sustaining dual career pathways over time.  相似文献

This longitudinal study aimed to examine how physical activity parenting (PAP) directly predicted objectively measured children’s moderate-to-vigorous physical activity (MVPA) and sedentariness over a three-year transitional period from early to middle childhood, and second, whether the children’s perception of motor competence (PMC) mediated or moderated the influence of PAP to children’s MVPA or sedentariness. At time 1 (T1), PAP and children’s (N = 396, mean age 5.80, SD 1.04) PA were assessed by parental questionnaire. Three years later, at time 2 (T2), children’s (N = 396, mean age 8.80, SD 1.04) PMC was measured by a validated pictorial scale, and MVPA and sedentariness were measured by accelerometers. All the analyses were conducted using the Mplus statistical package (Version 8.4). The models were adjusted for the following covariates: children’s PA (T1), gender (T1), age (T1), mean accelerometer measurement in hours per day (T2), and parents’ education level (T1). Results showed that PAP at T1 did not significantly predict level of MVPA or sedentary time at T2 and, therefore, PMC did not mediate the PAP-children’s MVPA or sedentary time relationship either. However, PMC significantly moderated the relationship between PAP and MVPA but not between PAP and sedentary time. The results suggested that parental support positively predicts children’s MVPA among children with low PMC but not among children with high PMC. This unique finding proposes that family-based PA interventions could benefit from screening of children with low PMC and provision of PA counselling to their parents.  相似文献

Researchers have documented benefits from receiving supportive messages high in verbal person‐centeredness (VPC), but the processes through which such messages produce longitudinal effects remain unclear. This study evaluated two perspectives (i.e., indirect effects and invisible support) that address how supportive messages can produce durable effects and tested sex differences in those effects. 255 dyads completed a laboratory‐based interaction in which level of VPC and sex of the support provider were manipulated. 3 weeks later, support receivers evaluated the conversations and their stressor. Variations in VPC produced durable effects both when messages were positively evaluated initially and when they were evaluated as supportive by providers or third‐party observers but judged low in supportiveness by receivers. Provider sex moderated the results.  相似文献
