Background and objectives: A long research tradition has investigated the impact of stress on university students by assuming that individuals have a limited reservoir of resources, and that negative events and circumstances progressively drain resources thereby producing exhaustion. A recent research tradition, instead, has focused on the detrimental consequences of discrepant levels of implicit (ISE) and explicit (ESE) self-esteem on the development of stress-related symptoms. The present research attempted to merge the aforementioned approaches, with the aim of explaining significant predictors of stress.

Design: Within the framework of a Longitudinal Structural Equation Model, we followed a moderated-mediated approach.

Method: A sample of university students (N?=?209; 66% females) completed a questionnaire battery including measures of ISE, ESE, perceptions of negative events, and emotional exhaustion. Participants were assessed once a week for eight consecutive weeks.

Results: ISE significantly moderated the relationship between ESE and negative events; in turn, the latter significantly predicted emotional exhaustion. Monte Carlo method for assessing mediation showed that negative events significantly mediated the relationship between incongruent self-esteem and emotional exhaustion.

Conclusions: The detrimental role of incongruent self-esteem has been corroborated. Practical implications and suggestions for future research dealing with stress in a university setting were provided.  相似文献

The Karamojong people of Uganda are marginalized and likely to have difficult lives. Research is needed to understand Karamojong children’s challenges, adjustment, and resiliency to help guide interventions and policies to improve their lives. Thus, 18 Karamojong 10–16-year-olds (10 girls; M?=?13.33 years; SD?=?1.81) were recruited from a nongovernmental organization in Tororo District, Uganda, and interviewed about their life events, coping strategies, social support, and hope. Adolescents also were verbally administered questionnaires about their life events and adjustment problems. Participants reported many negative life events (M?=?9.28 of 16). The number of negative life events was positively correlated with internalizing, but not with externalizing, problems. Participants described a variety of coping strategies. Most participants received emotional or instrumental social support, and were hopeful about their futures. Hardships were often alcohol- or poverty-related events, whereas hope was often centered on education.  相似文献

Participants (6- and 7-year-olds, N=130) participated in classroom activities four times. Children were interviewed about the final occurrence (target event) either 1 week or 4 weeks later, during which half of the event items were described inaccurately. Half of these suggestions were consistent with the theme of the detail across the occurrences (e.g., always sat on a kind of floor mat) or were inconsistent (e.g., sat on a chair). When memory for the target event was tested 1 day later, children falsely recognized fewer inconsistent suggestions than consistent suggestions, especially compared with a control group of children who experienced the event just one time. Furthermore, the longer delay reduced accuracy only for consistent suggestions. Source-monitoring ability was strongly and positively related to resistance to suggestions, and encouraging children to identify the source of false suggestions allowed them to retract a significant proportion of their reports of inconsistent suggestions but not of consistent suggestions. The results suggest that the gist consistency of suggestions determines whether event repetition increases or decreases suggestibility.  相似文献

The aims of this study are to compare the level of psychological distress between Norwegian born and immigrants from countries with different income levels and culture, and to investigate the explanatory effect of socioeconomic and psychosocial factors, with special emphasis on lack of control (powerlessness and self-efficacy). A cross-sectional survey with self-administered questionnaire was conducted in 2000-2001 in a sample of 15,723 adults living in Oslo. Psychological distress was measured by a ten-item shortened version of Hopkins Symptom Checklist-25 items, whereas psychosocial variables were measured by various instruments. The results show that the level of psychological distress is significantly higher in immigrants from low- and middle-income countries than in the Norwegian born and the immigrants from high-income countries. They also report more powerlessness, more negative life events, less social support, less income and less paid work. It is concluded that negative life events, mainly related to social network, somatic health and economic situations, as well as lack of social support, are important mediators between immigration from low- and middle-income countries to Norway and psychological distress. Powerlessness also plays a role, but this is mainly because of a concept overlap between psychological distress and powerlessness.  相似文献

This study examines the relation between family instability and child maladjustment over a 6-year period in 369 children from four communities. Measures were collected annually from kindergarten through fifth grade. In associative growth curve models, family instability trajectories predicted children's externalizing and internalizing behavior trajectories during this time period. High levels of family instability also incrementally predicted the likelihood of meeting criteria for a DSM IV diagnosis during elementary school, above and beyond prediction from earlier measures of maladjustment. However, the timing of family instability had a different effect on externalizing versus internalizing disorders. In general, stronger relations were found between family instability and externalizing behaviors relative to internalizing behaviors, although children with comorbid disorders experienced the highest levels of family instability.The Conduct Problems Prevention Research group is comprised of Karen L.

A recovery model of depression (Needles & Abramson, 1990 Journal of Abnormal Psychology, 99, 156-165) proposes that depressed individuals who exhibit an enhancing attributional style for positive events (i.e. make stable, global attributions) will be more likely to regain hopefulness and, thereby, recover from depression when positive events occur. While only a few studies have directly tested this model among clinical and nonclinical adult samples, none have tested a clinical sample of children and adolescents. Furthermore, prior studies testing this model have failed to examine the interactive role of an 'enhancing attributional style' for positive events with a 'depressogenic attributional style' for negative events, as prescribed by the hopelessness theory of depression (Abramson, Metalsky, & Alloy, 1989 Psychological Review, 96, 358-372). The current study presents data demonstrating that depressogenic and enhancing attributional styles interact to predict differential decreases in hopelessness. Implications of these findings and suggestions for future research also are presented.  相似文献

When children in foster care are reunified with their families of origin they encounter changes that may influence their well-being in both positive and negative ways. We examined the effects of reunification among 218 children in foster care to test an integrative model of the effects of reunification using structural equation modeling. We hypothesized that reunification would exert indirect effects on subsequent child adjustment via changes in adverse life events, perceived social isolation, and mental health service utilization. Results indicated no direct effect of reunification on subsequent internalizing problems, but reunification was related to increased adverse life events that, in turn, were related to elevated symptoms. Second, reunification was negatively associated with mental health service use. Finally, reunification was associated with decreased child perceptions of social isolation. In summary, reunification with biological parents is associated with multiple environmental changes, with most but not all effects indicating negative consequences.  相似文献

This article provides commentary on research published in the special section of the Journal of Applied Behavior Analysis devoted to establishing operations (EOs). Three major themes are highlighted: (a) identification of the influence of EOs on behavior in applied settings, (b) the use of EO manipulation as an assessment tool, and (c) the development of interventions based on the alteration of EO influences. Methodological issues pertaining to research on EOs are addressed, and suggestions for future investigation are provided.  相似文献

A statewide sample of 1735 Iowa residents, approximately half of whom were victims of the 1993 Midwest Floods, participated in interviews 1 year prior to, and 30 to 90 days after, the disaster. Employing a rigorous methodology including both control-group comparisons and predisaster assessments, we performed a systematic evaluation of the disaster's impact. Overall, the disaster led to true but small rises in depressive symptoms and diagnoses 60–90 days postflood. The disaster–psychopathology effect was not moderated by predisaster depressive symptoms or diagnostically defined depression; rather, predisaster symptoms and diagnoses uniquely contributed to increases in postdisaster distress. However, increases in symptoms as a function of flood impact were slightly greater among respondents with the lowest incomes and among residents living in small rural communities, as opposed to on farms or in cities. Implications for individual- and community-level disaster response are discussed.  相似文献

Exposure to chronic stress is associated with habitual learning in adults. We studied the origins of this association by examining the link between stressful life events and infant cognitive flexibility. The final sample consisted of N = 72 fifteen-month-old infants and their mothers. Mothers completed a survey on pre- and postnatal negative life events. To assess chronic stress physiologically, infant and maternal hair cortisol concentrations were determined for cortisol accumulation during the past 3 months. Each infant participated in two cognitive tasks in the laboratory. An instrumental learning task tested infants’ ability to disengage from a habituated action when this action became ineffective (Seehagen et al., 2015). An age-adequate version of the A-not-B task tested infants’ ability to find a toy at location B after repeatedly finding it at location A. Correlations between cortisol concentrations and postnatal negative life events (number, perceived impact) did not yield significance. Infant and maternal hair cortisol concentrations were not correlated. Infants’ ability to shift to a new action in either task, controlled for acute stress, correlated neither with pre- and postnatal negative life events nor with cortisol concentrations. Taken together, these results indicate that the potential link between long-term stress exposure and cognitive flexibility might not be present in samples with low levels of psychosocial stress.  相似文献
