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

In recent years, public science events have been designed as a means to foster a dialogue between science and the public and to contribute to ongoing policy processes. Regardless of their tangible outcome, such events rely on a certain framing, reconfigure scientific knowledge and conceptualise the public in specific ways. These constructs are exemplified by a science festival that was held in the train station hall in Zurich. Novel insights can be gained from a spatial, an object and an actor-related approach borrowed from the artistic context: the discussions about the White Cube can be adapted to contribute to the analysis of the science festival. When we look into the spatial situation created to foster exchange about scientific knowledge, we find how the exhibition display is taking care of minor details. While the organisers transformed the station hall into a laboratory, they created a kind of dialogic situation that filled an authority gap as it equally enabled exchange. The objects put in place in the exemplary case helped to design a customer–supplier relationship between the public and science. Under the umbrella of the science event, a range of diverse research endeavours was homogenised and unified. The audience, finally, was invited to familiarise itself with scientific knowledge. However, they were allocated a consumer role that obliged them to remain guests in the laboratory environment of the station hall. Thus, public science events may be successful in attracting large attendance and allowing more experiences with science, but while they create novel forms of familiarisation with science for visitors, they do not necessarily remedy public doubts about science and technology.  相似文献

The present study examined whether cognitive flexibility in the processing of emotional material (i.e., affective flexibility) predicts the use of rumination in response to negative events in daily life. One hundred fifty-seven undergraduate participants completed daily diaries for six consecutive days. Affective flexibility was measured with a novel task-switching paradigm using emotional pictures. Results show that affective inflexibility when switching away from processing the emotional meaning of negative material was associated with increased use of rumination in daily life. In contrast, affective inflexibility when switching away from processing the emotional meaning of positive material was related to decreased use of rumination. Importantly, affective flexibility predicted use of rumination beyond non-affective measures of executive functioning. This is the first study to show that inflexibility is not uniformly associated with increased rumination but that inflexibility in the processing of positive material can predict lower levels of rumination.  相似文献

Abstract

In a sample of 1528 college students, we examined (1) whether several risk factors prospectively predicted exposure to potentially traumatic events (PTEs) over a 2-month period and (2) whether dependent events (i.e., those more likely to depend upon one's behavior or characteristics) and independent events were predicted by different risk factors. Logistic regression analyses indicated that overall subsequent PTE exposure was higher for women, those with more previous PTEs, and those who engaged in more binge drinking. Female gender and previous PTE exposure also predicted exposure to independent events. Subsequent dependent PTE exposure was predicted by more previous PTEs and binge drinking, and was somewhat higher in ethnic minority students. Implications for prevention efforts are discussed.  相似文献

Although much research has demonstrated a relationship between negative life events and depressive symptoms, relatively little research has examined the mechanisms that may mediate this relationship. The theories of Blatt (1974), Bowlby (1980), and Gilbert (1992) each propose proximal predictors of depression. In accordance with these theories, this study examined the relationships among perceived losses in self-worth and interpersonal relationships, anaclitic (dependent) and introjective (self-critical) mood states, and depressive symptoms following a significant negative life event. A sample of 172 undergraduate students completed measures of depressive symptoms and depressive vulnerability factors and retrospectively described the worst period of their lives. They also rated the extent to which the events surrounding this worst period affected their self-worth and their relationships with close others. Structural equation modeling demonstrated that the effect of a perceived loss of self-worth on depressive symptoms was fully mediated by both introjective and anaclitic mood states, whereas the effect of a perceived loss of interpersonal relationships on depressive symptoms was fully mediated by an anaclitic mood state. Additionally, perceived losses of self-worth showed a stronger effect on introjective mood in highly self-critical individuals. Findings highlight the importance of perceived losses in both self-worth and interpersonal domains in response to adverse life events and suggest pathways through which perceived losses may affect depressive symptoms.  相似文献

Negative effects of psychological treatments is a fairly unexplored area of clinical research. Previous investigations have indicated that a portion of all patients experience negative effects in terms of deterioration and various adverse events. Meanwhile, evidence suggests that many clinicians are untrained in identifying negative effects and unaware of the current research findings. The objective of the current study is thus to investigate clinicians' own perspectives and experiences of possible negative effects of psychological treatments. An invitation to participate in an anonymous online survey consisting of 14 open-ended questions was distributed via three mailing lists used by clinicians that primarily identify themselves as cognitive behavior therapists. The responses were analyzed using a qualitative method based on thematic analysis. In total, 74 participants completed the survey. A majority agreed that negative effects of psychological treatments exist and pose a problem, and many reported having experienced both deterioration and adverse events among patients in their own practice. The thematic analysis resulted in three core themes: characteristics of negative effects, causal factors, as well as methods and criteria for evaluating negative effects. The clinicians recognize that negative effects exist, but many are unaware of the current research findings and are unfamiliar with methods and criteria for identifying and preventing deterioration and adverse events. The results provide evidence for further dissemination of the present knowledge regarding negative effects, particularly during basic clinical training, as well as the need for raising awareness of the available methods for identifying and preventing negative effects.  相似文献
