The universality versus cultural specificity of Mexican personality dimensions was investigated by examining: (a) the replicability of Mexican personality dimensions assessed by indigenous inventories; and (b) the extent to which Mexican dimensions are encompassed by the Five-Factor Model (FFM), one hypothesized universal model of personality structure. Mexican university students (N = 794) completed nine indigenous inventories and the Spanish version of the Revised NEO Personality Inventory. The FFM replicated well, although reliability was poor for a few facet scales. Reliability was acceptable for the indigenous Mexican scales. However, for most indigenous instruments, a cross-sample replication criterion suggested alternative structures of fewer, more replicable dimensions. Multiple regression and joint factor analyses revealed that most of the Mexican dimensions were well subsumed by the FFM. Thus, cultural differences did not involve clearly culture-specific dimensions, but more subtle differences in the salience or cultural flavor of particular traits. 相似文献

Studies of intervention for caregivers of older and dependent relatives are reviewed. National (PortalMayores, Psicodoc, Psyke) and international (Ageline, Cochrane Library, Medline, Psycinfo) databases were searched for randomized studies, published from 1980 to 2004, that attempt to reduce emotional distress in caregivers. Most intervention studies focus on caregivers of dementia patients and these caregivers are usually females. Caregivers are not an easy group to access. Intervention objectives and contents vary widely and they are not always well defined. The reported effects are moderate. Studies achieve significant outcomes in reducing distress from behavioural problems, but it is difficult to improve depression levels. Psychotherapeutic interventions have shown moderate efficacy. To conclude, future intervention studies should determine the theoretical framework clearly, as well as the goals, and should use more extensive followup periods. 相似文献

This study examined whether the participation in intermediate contact sports affects the opinions about the behaviors and attitudes of fair play in the sports context and whether these effects are influenced by ego orientation. The participants were high level sportsmen from university and professional basketball and football players (N = 131). They filled in questionnaires to assess their participation in sports, their goal orientations, and their fair play attitudes and behaviors. The analyses of the structural equation model indicated that participation in intermediate contact sports predicted ego orientation; these analyses consecutively predicted low levels of fair play. The direct effects of sports participation in fair play decreased significantly in the presence of ego orientation, indicating that the last construct partially mediates the relation between the first two variables. These discoveries help us to better understand the processes that operate in contact sports. Finally, their implications for eliminating unsportsmanlike behaviors are discussed. 相似文献

Contemporary research on interpersonal influence has shown that individuals scoring high in Need for Cognition (NC) are able to generate a large number of arguments in order to convince other people. However, research has also shown that such an effort does not necessarily lead them to be more persuasive or more efficient in their group performance. The present research analysed this state of affairs, replicating and extending previous research by showing that appropriate training in socio-emotional group dimensions can increase group performance for individuals high in NC. Potential underlying mechanisms for such an effect are discussed. 相似文献

Brain c-Fos immunocytochemistry and cytochrome oxidase histochemistry after a fear conditioning task
The involvement of the basolateral and the medial amygdala in fear conditioning was evaluated using different markers of neuronal activation. The method described here is a combination of cytochrome oxidase (CO) histochemistry and c-Fos immunocytochemistry on fresh frozen brain sections. Freezing behavior was used as an index of auditory and contextual fear conditioning. As expected, freezing scores were significantly higher in rats exposed to tone-shock pairings in a distinctive environment (conditioned; COND), as compared to rats that did not receive any shocks (UNCD). CO labeling was increased in the basolateral and medial amygdala of the COND group. Conversely, c-Fos expression in the basolateral and medial amygdala was lower in the COND group as compared to the UNCD group. Furthermore, c-Fos expression was particularly high in the medial amygdala of the UNCD group. The data provided by both techniques indicate that these amygdalar nuclei could play different roles on auditory and contextual fear conditioning. 相似文献

The aim of this study is to identify the variables related to stress and burnout syndrome among child residential care workers, as well as the most problematic areas of their work. A random sample of 257 professionals working in the Residential Child Care sector in Spain was studied by means of the TBQ questionnaire (Teachers' Burnout Questionnaire), adapted to child care workers. The results enabled us to detect the principal sources of job dissatisfaction, as well as revealing a greater incidence of stress than of burnout. Certain personal and work variables displayed relevant relationships with these measures. 相似文献

The psychometric properties of the d2 Selective Attention Test are analyzed in two samples of premature ( n = 63) and born-at-term ( n = 78) children. The reliability coefficients (internal consistency) reached values of around .90. Principal components analysis revealed a three-factor structure, which accounts for 58% of the variance, and thus coincides with the number of factors presented in the manual of the Spanish adaptation of the test but not with their composition. Results suggest that the d2 test has adequate psychometric properties both for the global sample and for each sub-sample. 相似文献

Presymptomatic testing for spinocerebellar ataxia type 2 (SCA2) in Cuba started five years ago. We have now investigated the
psychological impact of test results on 150 individuals at 50% risk for SCA2. In a prospective study, psychological instruments
were used to evaluate depression, anxiety and family functioning (1) before testing and (2) one year after disclosure of the
test result. One year after, anxiety and depression levels decreased both in carriers and non-carriers, but anxiety decreased
significantly more in carriers. Pathological levels of anxiety were seen mostly in members of dysfunctional families, but
decreased more in them than in other consultands. Presymptomatic testing thus seems to have been especially beneficial for
these testees, possibly due to a greater gain from the psychosocial support received. It would be pertinent to evaluate now
the impact of other psychosocial variables and perform longer-term longitudinal studies. 相似文献

During the last decade, a considerable amount of evidence has accumulated to show that oxytocin (OT) is involved with functions other than its classical roles in reproduction-associated processes, such as social recognition, maternal behavior and neuroendocrine regulation of the stress response. It has been shown, for instance, that post-training systemic administration of oxytocin in mice produces an amnestic effect on the step-through inhibitory avoidance. Since it is still unclear how systemic levels of OT may affect CNS memory processes, our aim here was to investigate the hypothesis that systemic OT effects on memory retrieval might be mediated through an oxytocin-induced decrease in glucocorticoid release. In our first experiment, we have found an amnestic effect of i.p. pre-test 0.4 microg/kg of OT upon memory retrieval in the inhibitory avoidance task (IA); this OT dose was shown to (a) significantly decrease plasma corticosterone levels when compared to the saline group, and (b) not to cause any anxiety effects by itself in a plus-maze task. At last, an ineffective-by-itself dose of dexamethasone was able to reverse the amnestic effect of this OT dose. Our results suggest that the amnestic effect of systemically administered oxytocin upon memory retrieval in the inhibitory avoidance task was probably caused by an oxytocin-induced decrease in glucocorticoid release from the adrenal gland. 相似文献
