A massive literature documents the inverse association between poverty or low socioeconomic status and health, but little is known about the mechanisms underlying this robust relation. We examined longitudinal relations between duration of poverty exposure since birth, cumulative risk exposure, and physiological stress in two hundred seven 13-year-olds. Chronic stress was assessed by basal blood pressure and overnight cortisol levels; stress regulation was assessed by cardiovascular reactivity to a standard acute stressor and recovery after exposure to this stressor. Cumulative risk exposure was measured by multiple physical (e.g., substandard housing) and social (e.g., family turmoil) risk factors. The greater the number of years spent living in poverty, the more elevated was overnight cortisol and the more dysregulated was the cardiovascular response (i.e., muted reactivity). Cardiovascular recovery was not affected by duration of poverty exposure. Unlike the duration of poverty exposure, concurrent poverty (i.e., during adolescence) did not affect these physiological stress outcomes. The effects of childhood poverty on stress dysregulation are largely explained by cumulative risk exposure accompanying childhood poverty.  相似文献

This study merged two theoretical constructs: cumulative risk and allostatic load. Physical (crowding, noise, housing quality) and psychosocial (child separation, turmoil, violence) aspects of the home environment and personal characteristics (poverty, single parenthood, maternal highschool dropout status) were modeled in a cumulative risk heuristic. Elevated cumulative risk was associated with heightened cardiovascular and neuroendocrine parameters, increased deposition of body fat, and a higher summary index of total allostatic load. Previous findings that children who face more cumulative risk have greater psychological distress were replicated among a sample of rural children and shown to generalize to lower perceptions of self-worth. Prior cumulative risk research was further extended through demonstration of self-regulatory behavior problems and elevated learned helplessness.  相似文献

The purpose of this study was to examine the impact of cumulative risk exposure in concert with maternal responsiveness on physiological indicators of chronic stress in children and youth. Middle-school children exposed to greater accumulated psychosocial (e.g., family turmoil, poverty) and physical (e.g., crowding, substandard housing) risk factors manifested higher levels of allostatic load, a physiological marker of cumulative wear and tear on the body caused by the mobilization of multiple, physiological response systems. This effect was longitudinal, residualizing allostatic load 3-4 years earlier when the youth were in elementary school. This effect, however, occurred only among adolescents with mothers low in responsiveness. Cumulative risk was also associated with dynamic cardiovascular processes in response to an acute stressor (mental arithmetic). Higher risk was associated with muted reactivity and slower, less efficient recovery in blood pressure. These dynamic cardiovascular effects occurred irrespective of maternal responsiveness.  相似文献

The main issue of this paper concerns the mediating role of risk appraisal in the relation between past and future behavior. We expected previous risky behavior to heighten risk appraisal, which, in turn, should stimulate preventive behavior. Results ofthree tests of this mediation hypothesis showed that past behavior was strongly related to future behavior; people who behaved hazardously in the past indicated that they tend to do so in the future. Generally, the expected relation between past behavior and risk appraisal was supported. More risky behavior in the past was associated with a heightened risk appraisal. Results also indicate a relation between risk appraisal and future behavior, but in the opposite direction as predicted. Heightened risk appraisal was related to increased levels of risk in future behavior. When predicting future behavior by both risk appraisal and past behavior the effect of risk appraisal on future behavior disappeared, while past behavior remained a strong predictor of future behavior. In a few cases risk appraisal still predicted future behavior when past behavior was controlled for. Unfortunately, these cases showed the opposite relation; i.e., heightened risk appraisal was related to more risky future behavior. Implications of these findings for research on the role of risk appraisal will be discussed.  相似文献

This study examined both the mediation effects of self-esteem and psychological well-being for the relationship between gratitude and depression in late adolescence. Two hundred and thirty-five Taiwanese university students completed the measures of gratitude, self-esteem, psychological well-being, and depression. Path analyses indicated that self-esteem and psychological well-being acted as full mediators of the association between gratitude and depression. The identified model also revealed a significant path from gratitude through self-esteem and psychological well-being to depression. A multi-group analysis found that the paths did not differ by genders. Implications for future research and limitations of the present findings are discussed.  相似文献

In studies of child development, the combined effect of multiple risks acting in unison has been represented in a variety of ways. This investigation builds upon this preceding work and presents a new procedure for capturing the combined effect of multiple risks. A representative sample of 2,899 British children had their cognitive development measured at 36 and 58 months of age along with 10 potential risks during this period of development. Comparing a cumulative index of these risks against the previously undocumented alternative of confirmatory factor analysis using formative measurement, this study found differences favouring the factor analysis. The factor analysis procedure demonstrated greater predictive power of children's cognitive development while it systematically tested two of the assumptions implicit in cumulative risk indices.  相似文献

Whereas the average age of earliest reportable personal memory among adults is 3 to 3½, there is considerable individual and group variability in the age of earliest autobiographical memory. Some of the variability is thought to be attributable to differential narrative socialisation. In the present research we tested the hypothesis that by virtue of later exposure to language, individuals born deaf to hearing parents will have earliest memories from later in life, relative to hearing individuals. The average age of single earliest identifiable memory for adults who are deaf and adults who are hearing did not differ. Nevertheless, adults who are deaf were found to have less dense representations of early autobiographical memories and to include in their narrative reports fewer categories of information, including visual-spatial information, relative to hearing adults. Participants' ratings of their memories on a number of dimensions were found to have low utility in predicting the content of autobiographical reports from both early and later in life (i.e., after age 10 years).  相似文献

Theory and research suggest that negative events in childhood (e.g., childhood abuse) may contribute to the development of a cognitive vulnerability to depression. A limitation of past research, however, is that the majority has focused on explicit cognitions (e.g., attributional style) and it remains unclear whether similar relations would be observed for more implicit measures of depressive cognitions. This study investigated the relation between young adults' reports of childhood abuse and their implicit depressive cognitions, as measured by the Implicit Association Test. As hypothesised, young adults reporting a history of childhood abuse exhibited stronger implicit associations for depression-relevant stimuli than did individuals with no abuse history. These results were maintained even after statistically controlling for the influence of current depressive symptom levels.  相似文献

We examined whether meaning in life and exposure to media mediate the association between religiosity and alcohol use among members of the Jewish-orthodox community in Israel. One hundred and ten young adult men self-identified as orthodox (n?=?57) or secular (n?=?53) participated in the study. Participants completed self-report measures designed to assess meaning in life, media exposure, alcohol use, and craving. Our findings show that orthodox participants consumed less alcohol and reported less alcohol craving compared to their secular counterparts. Importantly, search for meaning in life and media exposure mediated the relationship between religiosity and alcohol craving. Our findings suggest that religion provides a sense of meaning that serves as a protective factor against alcohol craving, supporting existential theories. Furthermore, our studies show that practices that are associated with a religious lifestyle such as low exposure to mass media also serve as protective factors for alcohol use and craving.  相似文献

The present study investigated young adults' self‐reported communication during sexual activity and its link to sexual and relational outcomes. The associations between two forms of communication during sexual activity (i.e., positive relational disclosures and erotic talk) and orgasm and relationship satisfaction were explored. Additionally, the study tested whether orgasm mediated the association between communication during sexual activity and relationship satisfaction. Three‐hundred and nineteen young adults (237 women, 82 men) ranging in age from 18–32 years (M = 19) completed a survey within 2 hours of a recent sexual episode addressing their communication during sexual activity. Results revealed that positive relational disclosures, but not erotic talk, predicted the likelihood of orgasm, controlling for participants' biological sex. More specifically, individuals who disclosed more positive feelings during sexual activity were more likely to orgasm. Additionally, the more individuals disclosed positive thoughts and feelings for their partners during sexual activity or the more they engaged in mutualistic erotic talk that included intimacy and bonding, the higher their reported relationship satisfaction after sexual activity. The implications of these findings for research on sexual satisfaction, relational health, and the post sex disclosures model are discussed.  相似文献

Two experiments implement and evaluate a training scheme for learning to apply frequency formats to probability judgements couched in terms of percentages. Results indicate that both conditional and cumulative probability judgements can be improved in this manner, however the scheme is insufficient to promote any deeper understanding of the problem structure. In both experiments, training on one problem type only (either conditional or cumulative risk judgements) resulted in an inappropriate transfer of a learned method at test. The obstacles facing a frequency‐based training programme for teaching appropriate use of probability data are discussed. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Optimism bias is a crucial feature of risk perception that leads to increased risk‐taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high‐stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory‐13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators.  相似文献

I used longitudinal data to examine relationships between sibling variables and young adults' status attainment at different levels, based on earlier measures of adolescents' educational and occupational aspirations. My analyses involved 21-year-old Australians from Anglo-Australian, Greek, and Southern Italian families. Regression surfaces were plotted from models that included terms to test for possible linear, interaction, and curvilinear associations among the variables. My study showed that the number of children in a family and birth order continue to be significantly associated with young adults' status attainment, even after incorporating the mediating influences of adolescents' aspirations. The investigation also suggested ethnic group differences among sibling variables, adolescents' aspirations, and young adults' status attainment.  相似文献

ObjectiveThe purpose of this study is to assess the potential unique and relative mediating effects of three interpersonal risk factors (i.e., excessive reassurance-seeking [ERS], negative feedback seeking [NFS], and rejection sensitivity [RS]) in the relationship between childhood emotional abuse (CEA) and depressive symptoms.MethodOne hundred eighty-five undergraduates were followed over a four-month interval. Participants completed assessments of childhood abuse history, ERS, NFS, and RS, and depressive symptoms at baseline, as well as depressive symptoms at four-month followup.ResultsFindings from single-mediator analyses indicated that RS and NFS, but not ERS, mediated the relationship between CEA and prospective depressive symptoms, after accounting for childhood sexual and physical abuse, as well as baseline depressive symptoms. In our multi-mediator model, only RS remained a significant mediator of the relationship between CEA and prospective depressive symptoms.ConclusionsThe current study provides preliminary evidence that negative behavioral styles may function as a mechanism linking prior experiences of CEA to subsequent depressive symptoms. Clinical implications of these findings suggest that targeting maladaptive behavioral tendencies, particularly RS, may be an effective adjunct in behavioral modification treatments of CEA victims at risk for depression.  相似文献

Abstract Using the general strain theory as a theoretical framework, the present longitudinal study investigated both face-to-face and cyber victimization in relation to cyber-displaced aggression. Longitudinal data were collected from 130 (70 women) young adults who completed measures assessing their victimization (face-to-face and cyber), cyber aggression, and both face-to-face and cyber-displaced aggression. Findings indicated that victimization in both social contexts (face-to-face and cyber) contributed to cyber-displaced aggression 6 months later (Time 2), after controlling for gender, cyber aggression, face-to-face displaced aggression, and cyber-displaced aggression at Time 1. A significant two-way interaction revealed that Time 1 cyber victimization was more strongly related to Time 2 cyber-displaced aggression when young adults had higher levels of face-to-face victimization at Time 1. Implications of these findings are discussed as well as a call for more research investigating displaced aggression in the cyber context.  相似文献

Social-class discrimination is evident in many societies around the world, but little is known about its impact on the poor or its role as an explanatory variable in the link between socioeconomic status and health. The current study tested the extent to which perceived discrimination explains socioeconomic gradients in physical health. Participants were 252 adolescents (51% male, 49% female; mean age = 17.51 years, SD = 1.03 years) who participated in Wave 3 of an ongoing longitudinal study focusing on the developmental consequences of rural poverty. Physical health was operationalized as allostatic load, a measure of cumulative wear and tear on the body caused by overactivation of physiological systems that respond to stress. Mediation analyses suggested that 13% of the effect of poverty on allostatic load is explained by perceived discrimination. The findings suggest that social-class discrimination is one important mechanism behind the influence of poverty on physical health.  相似文献
