Predictors of HIV-related stigma among young people living with HIV.   总被引:2,自引:0,他引:2  
Enacted and perceived HIV stigma was examined among substance-using young people living with HIV (YPLH) in Los Angeles, San Francisco, and New York City (N = 147). Almost all YPLH (89%) reported perceived stigma, and 31% reported enacted experiences in the past 3 months; 64% reported experiences during their lifetime. The HIV stigma questions were characterized by factors of avoidance, social rejection, abuse, and shame. In multivariate models, enacted stigma was associated with gay or bisexual identity, symptomatic HIV or AIDS, and bartering sex. Perceived stigma was associated with female gender, symptomatic HIV or AIDS, bartering sex, lower injection drug use, and fewer friends and family knowing serostatus. Gay or bisexual YPLH who were also HIV symptomatic or AIDS diagnosed experienced more HIV stigma than their heterosexual peers.  相似文献

Gender role flexibility has been conceptualized as a multi-dimensional construct that consists of attitudes, self-perceptions, and behaviors. The present study was designed to examine the developmental trajectory of gender role attitude flexibility, self-perception flexibility, and gender-typed behavioral flexibility during early adolescence. One hundred and thirty six male and female sixth grade students completed the Children’s Occupations, Activities, and Traits Scale (Liben & Bigler, 2002) during the fall and spring of their first 2 years of middle school and they kept monthly after-school activity diaries, which were coded for gender stereotypicality. Each component of flexibility exhibited a different pattern of developmental change consistent with the multi-dimensional view of gender role flexibility.  相似文献

The aim of this study was to investigate the psychological impact of Kangaroo Mother Care (KMC) on mother‐infant bonding in cases of premature delivery. Examined variables were mother‐infant relationships, maternal anxiety levels, and infant interactive signals. The KMC method requires that babies be undressed and held upright between their mother's breasts for a minimum of 1 hr a day, from birth until they are discharged from hospital. The present study examined 40 premature infants and their mothers, with 21 dyads experiencing KMC and 19 receiving traditional care (TC). Maternal emotional stress was assessed with the Parent Stress Index‐Short Form questionnaire (Abidin, 1990), and mother‐newborn interactive style was assessed with the Nursing Child Assessment Feeding Scale (Barnard, 1975). Results revealed a better mother‐infant interactive style, a significant decrease in maternal emotional stress, and better infant ability to make requests and respond to parental interactive style in the KMC group.  相似文献

The basic assumption in the Dutch dominant discourse on integration is that knowledge of the Dutch language when combined with education is the key factor for integration into society. The aim of this article is to show how female refugees who have completed higher education in the Netherlands experience the process of integration into the Dutch labour market through contacts with and in Dutch organizations. We situate the narratives of these women in the broader discursive context of the Netherlands and show what these experiences can tell us about the policies and debates on integration in the Netherlands.  相似文献

A new instrument, the Object‐Spatial Imagery Questionnaire (OSIQ), was designed to assess individual differences in visual imagery preferences and experiences. The OSIQ consists of two scales: an object imagery scale that assesses preferences for representing and processing colourful, pictorial, and high‐resolution images of individual objects and a spatial imagery scale that assesses preferences for representing and processing schematic images, spatial relations amongst objects, and spatial transformations. Across a series of studies, the object imagery scale was significantly correlated with the performance on object imagery tasks; the spatial imagery scale was significantly correlated with the performance on spatial imagery tasks; but neither correlated with measures of intelligence. Additionally, compared to visual artists and humanities professionals, scientists reported higher spatial imagery ratings; however, compared to scientists and humanities professionals, visual artists reported higher object imagery ratings. Thus, the results from the studies supported the predictive, discriminant, and ecological validity of the OSIQ. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

This investigation examined the predictors of the acceptance of waste incineration facilities. A survey was conducted of a random sample of the residents in two sites where an incinerator was planned (450 participants in Study 1 and 300 in Study 2). Attitudes towards the incinerator were mainly predicted by the perception of the risks as dread, positive expectancies about the project, trust in social actors involved in the process, perceived distributive justice, and distance of residence to the site. The relationship between distance of residence and attitude towards the incinerator was partially mediated by perceived risk, perceived justice, and expectations. As expected from the elaboration likelihood model, substantive peripheral cues were better predictors of attitudes for involved than for noninvolved dwellers.  相似文献

Documenting the behavioural consequences of infra‐humanization, Vaes, Paladino, Castelli, Leyens, and Giovanazzi ( 2003 ) found that, in comparison to in‐group members, out‐group members are discriminated against when they express uniquely human emotions. It was assumed that expressing a uniquely human emotion makes an in‐group member, at least tacitly, more human than an out‐group member. Two studies tested this assumption and found, as predicted, that the human concept was more activated in an in‐group compared to an out‐group context when group members were associated with uniquely human emotions. The possible impact of valence was controlled for, showing that both positive and negative emotions endorsed the same effects (Study 1) and that the activation of the human concept was not a side effect of increased positivity (Study 2). The discussion focuses on the implications of the present studies and suggests new avenues of research. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

This study explored the information received about menstruation by Mexican women as well as their reactions to menarche. The most important topics that teenagers, young women, and middle-aged women were informed about were menstrual hygiene and physiology. In contrast, senior citizens were more informed about hygiene and activity restrictions. Regarding their reactions to menarche, teenagers and young women reported being confused. Positive reactions were reported only by older women who had knowledge about menstruation prior to menarche. Finally, younger women were more likely to present ambivalent reactions to menarche, probably because they are exposed to mixed messages which are often contradictory, resulting in more confusion and ambivalence.  相似文献

We compare matching of facial expressions of emotion, completion of the positive valence of emotional expression, attunement of emotional intensity, and non-matching of emotion, in engagements with their mothers of firstborn dizygotic twins and of singletons. Nine twins and nine singletons were video-recorded at home in spontaneous face-to-face interactions from the second to the sixth month after birth. Microanalysis of infant and maternal facial expressions of emotion revealed qualitative and quantitative differences that indicate that engagements with twins had more frequent and more accurate emotional matching and attunements compared to those with singletons. Singletons displayed more emotional completion and non-matching reactions. Expressions of matching for pleasure and interest followed different developmental patterns in the two kinds of dyads. These results are discussed in relation to the theory of innate affective intersubjectivity. Differences may shed light on the relationship between sharing early life with a twin, and development of self-other awareness.  相似文献

Subjective well-being concerns an evaluation of one’s life, considering cognitive and affective aspects. Contextual factors, such as family, may influence this process. One of the main development contexts of children is family and aspects of these relationships, such as different settings, might contribute to children’s subjective well-being. The aim of this study was to compare the well-being of children from different family settings (intact, single-parent, stepfamilies, multigenerational). Participants were 2,135 boys and girls, from 9 to 13 years old (M = 10.97, SD = 0.99), students of public and private schools from a Brazilian southern State. Children answered a questionnaire with sociodemographic variables and three well-being scales (PWI-SC, BMSLSS, GDSI). Children were divided in four groups according to whom they live with (intact, single-parent, stepfamilies, multigenerational families). To evaluate differences between groups a Multivariate Analysis of Variance (MANOVA) were performed, considering well-being scales as dependent variables and family setting as independent variable. Results indicated significant differences in the well-being of children in relation to their family setting and age. Children from intact families showed significant positive differences on the well-being from children of other settings (the lowest means were from the children of stepfamilies). It is argued that transitions and instability that children are being subjected to may affect their well-being.
