Self-esteem is defined as sense of self-worth and self-respect, being crucial for understanding people’s well-being and success. It is one of the most studied constructs in the social sciences, with the Rosenberg Self-Esteem Scale (RSES) being the most used measure. Across four studies (N = 1450), we tested the psychometric parameters of an abbreviated version of the RSES. Through Item Response Theory, the five best items were selected to form the unidimensional Brief Rosenberg Self-Esteem Scale (B-RSES), a reliable and valid measure of self-esteem, which is invariant across age groups and gender. In addition, both RSES and B-RSES correlated very similarly with the Big Five Personality Factors. Also, the B-RSES was strongly correlated with three other short measures of self-esteem, besides being more strongly associated with a range of variables such as conscientiousness and self-competence in comparison to the other three short scales. Together, the B-RSES is especially useful in research that requires rapid evaluation and the use of multiple variables.
This experiment explored whether the benefits of a complete recategorization and a dual identity might effectively be translated into an intervention program designed to reduce prejudice among European Portuguese and African Portuguese 9‐ to 11‐year‐old children. Participants interacted for 45 minutes in weekly sessions for a month. One month after the last interaction, measures were administered to the children. Results revealed that only recategorization reduced prejudice over time relative to the control condition. Consistent with a functional perspective regarding which representation would most effectively promote their group's goals, a one‐group representation was more effective for the African Portuguese minority group. 相似文献
This paper systematically reviews empirical research published from 2002 to July 2015 investigating journalists’ occupational stressors, coping strategies, and the impacts of these variables on the health and well-being of such professionals, whether on their daily work or as special envoys to critical scenarios. A meta-analytic approach was displayed to analyse the association between exposure to traumatic events during work and journalists’ symptoms of post-traumatic stress disorder (PTSD). Twenty eight articles met the inclusion criteria and revealed that very few studies distinguish (and none compare) the distress of journalists in their daily work from the distress of reporting major disasters, not a single study addressed positive emotional responses and only one research study focused on an in-depth analysis of the most commonly used coping strategies by journalists. The impacts of occupational stress among these professionals were sorely negative (e.g., burnout, PTSD), and no study was found to address the design and assessment of preventive interventions for these impacts on the health and well-being of journalists. Thirteen studies were included in a random-effects model meta-analysis and a small to moderate effect size (r = 0.272) between exposure to traumatic events during assignments and PTSD was found. The article closes with directions for future studies. 相似文献
A measure of subjective social status (SSS) was examined among high (White), and low (Black and Roma) ethnic status children in Portugal within a developmental design including 6–8‐year‐old and 9–12‐year‐old children. White children favoured their in‐group over the Black and Roma out‐groups on the SSS measure, social preferences and positive as well as negative trait attributions. Generally, the Black and Roma showed equal SSS, preferences and trait attribution for their in‐group and the high status White out‐group, but not the other low‐status out‐group. With age White children generally demonstrated higher SSS for Black and Roma, preferred them more and attributed more positive traits. For low‐status groups, an age effect was found only for Black children who preferred the Roma more with age and attributed more positive traits. Changes on preferences and trait attribution depending on age‐group were mediated by SSS. It is concluded that minority group's SSS does not parallel the objective status hierarchy but, rather, is a dynamic reorganisation of group's relative positions serving strategies to cope with their minority condition. 相似文献
The aim of the present study was to evaluate the occurrence of fear sensitization in rats previously treated with an inhibitor of the NO syntheses and submitted to Trial1/Trial2 plus-maze (PM) procedure. Male Wistar rats received a systemic treatment with N(omega)-nitro-L-Arginine-methyl ester (L-NAME; 5, 10 or 50 mg kg(-1)) and were submitted to PM Trial1. In the following day the animals were re-exposed to the PM with no drug administration (Trial2). Some standards spatial-temporal measures, such as the percentage of entries (% Open arm entries) and time spent (% Open arm time) in the open arms and risk assessment frequency were recorded and used to estimate the animal level of fear sensitization in PM Trial2. The results showed that animals receiving L-NAME (50 mg kg(-1)) displayed increased % Open arm entries and % Open arm time in Trial2 in relation to the group receiving 0.9% saline, which is compatible with impaired fear/anxiety acquisition during Trial1/Trial2 PM procedure. In addition, rats treated with L-NAME (50 mg kg(-1)) exhibited low level of risk assessment in Trial2 in relation to the group treated with 0.9% saline, which indicates low level of fear/anxiety during PM re-exposure. The number of entries into the enclosed arms was not changed by any L-NAME treatment, which suggests no bias of the drug treatments on animal locomotor activity. The data suggest that NO synthesis may mediate the fear sensitization process in the PM. 相似文献
The present research examined the developmental course of racial behaviours in childhood. It tested the hypothesis that White children's expressions of racial prejudice do not necessarily decline in middle childhood due to the development of particular cognitive skills but that instead, as argued by the socio-normative approach, children older than seven will go on expressing prejudiced attitudes under appropriate conditions. This would be explained by the presence of an anti-racism norm, along with the existence of values promoting equal rights, which impede blatant expressions of racism. In the first study 283 White children aged 6-7 and 9-10 years performed a task of resource allocation to White and Black target children in conditions of high (White interviewer was present) or low (White interviewer was absent) salience of the anti-racist norm. The 6- to 7-year-old children discriminated against the Black target in both conditions whereas older children discriminated against the Black child only when the anti-racist norm was not salient. In Study 2, 187 White children aged 6-7 and 9-10 years performed the same resource allocation task in conditions of explicit activation of similarity vs dissimilarity or egalitarian vs merit-based norms regarding race relations. Supporting the hypothesis of the role of racist or anti-racist norms on the expression of intergroup discrimination, results have again shown that 6- to 7-year-old children discriminated against the Black target in both conditions while older children presented significantly different prejudiced/nonprejudiced behaviours consistent with the activated norms. These results were discussed in terms of the need for a reanalysis of the assumptions and research results of the cognitive-developmental theory and of further developments in the socio-normative approach regarding the development of prejudice in childhood. 相似文献
“In Another Country” draws upon Hemingway's experiences during World War I. Narrated by a wounded young American, this story is a parable of early machine-rehabilitation therapy, one in which the strong optimism of a physician employing new machines is contrasted with the skepticism of an Italian major (“the greatest fencer in Italy”) who, disbelieving in the machines, nevertheless comes regularly for therapy to his hand. That daily attendance is interrupted only when the major's young wife dies suddenly. The major, who had instructed the American never to put himself “in a position to lose,” has himself just “lost” the wife he had married when he felt sure that his own wounding had effectively taken him out of danger of being killed at the front. His continued stoicism offers the young soldier an example of ethical and moral behavior, for after her funeral he resumes his daily routine of machine-therapy. Seen against the ineffectiveness of the machines, the major's behavior seems to offer an example of the only “therapy” possible in this world of wounds and machines. 相似文献
