Positive future expectations can facilitate optimal development and contribute to healthier outcomes for youth. Researchers suggest that internal resources and community‐level factors may influence adolescent future expectations, yet little is known about the processes through which these benefits are conferred. The present study examined the relationship between contribution to community, neighborhood collective efficacy, purpose, hope and future expectations, and tested a mediation model that linked contribution to community and collective efficacy with future expectations through purpose and hope in a sample of 7th grade youth (N = 196; Mage = 12.39; 60 % female; 40 % African American; 71 % economically disadvantaged). Greater collective efficacy and contribution to community predicted higher levels of hope and purpose. Higher levels of hope and purpose predicted more positive future expectations. Contribution to community and neighborhood collective efficacy indirectly predicted future expectations via hope. Implications of the findings and suggestions for future research are discussed. 相似文献

Personalizing communication means creating persuasive messages that refer to aspects of a person's self. Although the use of personalization is increasing, research on its effectiveness is limited and the results are mixed. This study examined the persuasiveness of personalized e-mail newsletters in terms of increased attention, cognitive activity, evaluation, attitude, intention, and behavior by means of an experiment (n=109). Participants randomly received either a personalized or a generic newsletter advertising a sports center. Personalization triggered a more positive evaluation of the message; however, it did not influence the other effect variables. The effects were moderated by consumers' need for uniqueness, trust, and privacy concerns, suggesting that personalization is a good strategy to increase message evaluation only among individuals who have a high need for uniqueness. 相似文献

This study examined whether participation in elite sport interacts with stress in decreasing or increasing symptoms of depression and anxiety among adolescents, and further, whether the interplay between participation in high-performance sport and stress is related to the perceived quality of sleep. 434 adolescents (278 girls, 156 boys; age: M = 17.2 yr.) from 15 "Swiss Olympic Sport Classes" and 9 conventional classes answered a questionnaire and completed a 7-day sleep log. Analyses of covariance showed that heightened stress was related to more depressive symptoms and higher scores for trait-anxiety. Moreover, those classified as having poor sleep by a median split cutoff reported higher levels of depressive symptoms. No significant (multivariate) main effects were found for high-performance sport athletes. Similarly, no significant two- or three-way interaction effects were found. These results caution against exaggerated expectations concerning sport participation as a stress buffer. Nevertheless, participation in high-performance sport was not found to be an additional source of distress for adolescents who reported high stress levels despite prior research that has pointed toward such a relationship. 相似文献

The aim of the present study was to evaluate a factor mixture-based taxonic-dimensional model of anxiety sensitivity (AS)
(Bernstein et al. Behavior Therapy 41:515-521, 2010), as measured by the ASI-3 (Taylor et al. Psychological Assessment 19:176-188, 2007), in regard to panic attacks, anxiety symptoms, and behavioral impairment among a university sample (N = 150, n
females
= 107, M
age = 21.3 years, SD = 4.3) and a clinical sample (N = 150, n
females
= 102, M
age = 39.0 years, SD = 12.0) from Mexico City, Mexico. Findings demonstrated cross-national support for the conceptual and operational utility
of the AS taxonic-dimensional hypothesis (Bernstein et al. Journal of Anxiety Disorders 20:1-22, 2007b). Specifically, (1) the FMM-based AS taxon class base rate was significantly greater among the clinical relative to the university
sample; (2) risk for panic attacks was significantly greater among the AS taxon class relative to the AS normative class;
and (3) continuous individual differences in AS physical and psychological concerns, within the AS taxon class, were associated
with level of risk for panic attacks, as well as panic attack severity and anxiety symptom levels. Similar AS taxonic-dimensional
effects were observed in relation to degree of behavioral impairment across domains of functioning. The study results are
discussed with respect to their implications for better understanding the nature of AS-related cognitive vulnerability for
panic and related anxiety psychopathology. 相似文献

Children raised in families with low socioeconomic status (SES) go on to have high rates of chronic illness in adulthood. However, a sizable minority of low-SES children remain healthy across the life course, which raises questions about the factors associated with, and potentially responsible for, such resilience. Using a sample of 1,205 middle-aged Americans, we explored whether two characteristics--upward socioeconomic mobility and early parental nurturance--were associated with resilience to the health effects of childhood disadvantage. The primary outcome in our analyses was the presence of metabolic syndrome in adulthood. Results revealed that low childhood SES was associated with higher prevalence of metabolic syndrome at midlife, independently of traditional risk factors. Despite this pattern, half the participants raised in low-SES households were free of metabolic syndrome at midlife. Upward social mobility was not associated with resilience to metabolic syndrome. However, results were consistent with a buffering scenario, in which high levels of maternal nurturance offset the metabolic consequences of childhood disadvantage. 相似文献

There is considerable evidence that neuroimaging findings can improve the early diagnosis of Wernicke's encephalopathy (WE) in clinical settings. The most distinctive neuroimaging finding of acute WE are cytotoxic edema and vasogenic edema, which are represented by bilateral symmetric hyperintensity alterations on T2-weighted MR images in the periphery of the third ventricle, periaqueductal area, mammillary bodies and midbrain tectal plate. An initial bout of WE can result in Korsakoff's syndrome (KS), but repeated bouts in conjunction with its typical comorbidity, chronic alcoholism, can result in signs of tissue degeneration in vulnerable brain regions. Chronic abnormalities identified with neuroimaging enable examination of brain damage in living patients with KS and have expanded the understanding of the neuropsychological deficits resulting from thiamine deficiency, alcohol neurotoxicity, and their comorbidity. Brain structure and functional studies indicate that the interactions involving the thalamus, mammillary bodies, hippocampus, frontal lobes, and cerebellum are crucial for memory formation and executive functions, and the interruption of these circuits by WE and chronic alcoholism can contribute substantially to the neuropsychological deficits in KS. 相似文献

The primary aim of this research was to assess the adequacy of postexperimental inquiries (PEI) used in deception research,
as well as to examine whether mood state, reward, or administering the PEI as a face-to-face interview or computer survey
impacts participants’ willingness to divulge suspicion or knowledge about a study. We also sought to determine why participants
are not always forthcoming on the PEI. Study 1 examined how frequently PEIs are included in research and found that most researchers
employing deception do use a PEI. Studies 2 and 3 showed that participants are often unwilling to divulge suspicion or awareness
of deception or to admit to having prior knowledge about a study, though offering a reward and completing the PEI on a computer
modestly improved awareness and admission rates. Study 4 indicated several reasons why participants may not reveal suspicion
or knowledge about a study on the PEI. 相似文献
