In this study, the authors investigated the degree to which a family investment model would help account for the association between family of origin socioeconomic characteristics and the later educational attainment of 451 young adults (age 26) from 2-parent families. Parents' educational level, occupational prestige, and family income in 1989 each had a statistically significant direct relationship with youths' educational attainment in 2002. Consistent with the theoretical model guiding the study, parents' educational level and family income also demonstrated statistically significant indirect effects on later educational attainment through their associations with growth trajectories for supportive parenting, sibling relations, and adolescent academic engagement. Supportive parenting and sibling relations were linked to later educational attainment through their association with adolescent academic engagement. Academic engagement during adolescence was associated with educational attainment in young adulthood. These basic processes operated similarly regardless of youths' gender, target youths' age relative to a near-age sibling, gender composition of the sibling dyad, or gender of parent.  相似文献

Using a 5‐year longitudinal study, we investigated the long‐term effects of courses with ethnic studies content and courses with Latino or Black professors on university students' intergroup attitudes. We found that these curricular variables significantly affected the intergroup attitudes of students beyond pre‐existing differences in attitudes and beyond other curriculum variables. As expected, we found differences between ethnic groups: White students showed movement toward other groups as a result of these curricular factors, whereas Latino and African American students showed both increased tolerance toward other groups and movement toward the in‐group. The results are discussed in terms of group status differences between the dominant White majority and the stigmatized Latino and Black minority groups.  相似文献

The authors examined the influence of fraternity men's expectancies regarding secondhand consequences of excessive drinking behavior on normative standards regarding alcohol use and consumption levels. Participants were 381 men from 26 chapters of 2 national fraternities. One organization participated in a brief intervention involving discussion of secondhand consequences of excessive drinking. Immediate influence of the intervention on perceived secondhand consequences of alcohol use was assessed using a posttest-only, randomized groups design. Results supported a hypothesized measurement model with 1 overall secondhand consequence expectancy construct and 4 subfactors: (a) Noise Disruptive of Sleep and Study, (b) Violence, (c) Sexual Assault, and (d) Property Damage. Cross-sectional analysis at the chapter and individual levels demonstrated that secondhand expectancies had an indirect effect on alcohol consumption, mediated by personal consumption standards for limiting alcohol consumption. The intervention had an effect on secondhand expectancies. Findings suggest that interventions with intact groups can increase secondhand expectancies regarding excessive drinking and may lead to a reduction in excessive alcohol consumption.  相似文献

People may exhibit two kinds of modifications when demonstrating action for others: modifications to facilitate bottom-up, or sensory-based processing; and modifications to facilitate top-down, or knowledge-based processing. The current study examined actors' production of such modifications in action demonstrations for audiences that differed in their capacity for intentional reasoning. Actors' demonstrations of complex actions for a non-anthropomorphic computer system and for people (adult and toddler) were compared. Evidence was found for greater highlighting of top-down modifications in the demonstrations for the human audiences versus the computer audience. Conversely, participants highlighted simple perceptual modifications for the computer audience, producing more punctuated and wider ranging motions. This study suggests that people consider differences in their audiences when demonstrating action.  相似文献

The present study examined prevalence of lack of a close confidant in a medically underserved primary care sample, and evaluated demographic, medical, and psychological correlates of patients' deficits in close, personal contact. Adult patients (n = 413) reported on confidant status and symptoms of depression and anxiety. Sociodemographic and medical information were obtained through chart review. One-quarter of patients endorsed lack of a close confidant. Past month anxiety and depression symptoms, but not medical status, were associated with unmet socioemotional needs. Implications for primary healthcare interventions are discussed.  相似文献

To date, the feasibility of computer‐aided psychotherapy as an intervention has only been recognised in primary care practice. The present study sought to evaluate the impact of ‘Beating the Blues’ (BtB), an established computerised cognitive behaviour therapy (CCBT) self‐help programme for the management of anxiety and depression, within an NHS CBT specialist healthcare centre. Of the 555 service users who used BtB as part of routine care, with follow‐up assessment at six to eight weeks, 71% completed all eight sessions. Statistically significant differences on the Beck Depression Inventory‐II (BDI‐II) and Beck Anxiety Inventory (BAI) were found in completer and intention‐to‐treat analyses; 50% of completers achieved reliable change on the BDI‐II and approximately 25% of completers achieved reliable and clinically significant change on both measures. Outcomes were benchmarked against outcomes in studies of routine face‐to‐face CBT. These findings provide evidence that BtB may be of value to service users in secondary mental healthcare centres, alleviating current burdens on public health and therapeutic resources. Future research directions should include examining which factors influence individuals’ decisions to try computer‐aided psychotherapy, which individuals are best suited to using these interventions, and why some users drop out prior to programme completion.  相似文献

The 9 members of the Institute for Rational-Emotive Therapy’s International Training Standards and Review Committee (of which Albert Ellis is currently one) predict the status of Rational Emotive Behavior Therapy (REBT) after the death of Albert Ellis, its progenitor. Most respondents addressed whether REBT will exist in its own right or be subsumed under the broad umbrella of Cognitive Behavior Therapy.

Objectification theory posits that the tendency to view oneself as an object to be looked at and evaluated by others negatively affects girls', but not boys', subjective well-being. Although it has been established that women self-objectify more than men, research in this area has been limited to the study of adult college women. The aim in the current longitudinal study was to investigate the role of body shame and rumination in the link between self-objectification and depression among a community sample of girls and boys at ages 11 and 13. Results indicated that adolescent girls reported higher levels of self-objectification, body shame, rumination, and depression than boys. The findings support a model in which body shame and rumination mediate a direct relation between self-objectification and depression among girls; developmentally, the gender difference in self-objectification appears before the gender differences in rumination and depression.  相似文献

Scholars who study close relationships often measure the same concept with both observational ratings and questionnaire items. In studies where this has been done, the correlations between the two measures have often been low, and one reason may be a "context by measurement" confound. Observational ratings are usually based on behaviors during a specific task, whereas most questionnaire responses are based on a broader context such as "during the past month." In 2001, a total of 292 young couples were videotaped during a discussion task and asked to report on their own behavior and that of their partner during the discussion task and during the past month. The data were configured as a multitrait, multimethod matrix, and the magnitudes of the correlations were estimated with confirmatory factor analysis. The resulting correlations between observer ratings and questionnaire reports of hostile behavior during the videotaped discussion were roughly twice the magnitude of the correlations between observer rating and questionnaire reports during the past month. This suggests that the correspondence between behavioral categories and the content of questionnaire items is greater than previous studies have indicated.  相似文献
