This study aimed to assess sexual risk behaviour and its social correlates in HIV-infected women living in rural South Africa at six and twelve months post-partum. Participants were 699 HIV-positive women recruited prenatally by systematic sampling from twelve community health centres in Mpumalanga province, South Africa (mean age = 28.4 years, SD = 5.7; married =41.1%; serodiscordant or unknown partner status = 74.9%). They self-reported on their sexual activity six to twelve months after delivery; including use of condoms and partner involvement. Generalised linear mixed models were utilised to estimate unsafe sex outcomes from a prevention of mother to child transmission (PMTCT) intervention, socio-demographic factors, disclosure, and male involvement. About 20% of sexually active women in the past week had used condoms inconsistently at six and twelve months after delivery. Moreover, 16% and 18% of the women had not used a condom at last sex and 11% and 13% had unprotected sex with HIV-uninfected or unknown-status partners following delivery at six and twelve months, respectively. Higher inconsistent condom use was likely with lower male involvement. Promotion of condom use post-partum, as well as male involvement in sexual decisions, are important for safer sex post-partum by seropositive women.  相似文献

Emotional availability (EA) characterizes a warm, close relationship between caregiver and child. We compared patterns (clusters) of EA on risk factors, including those for borderline personality disorder (BPD). We sampled 70 children aged 4 to 7 years from low socio‐economic backgrounds: 51% of whose mothers had BPD. We coded filmed interactions for EA: mothers' sensitivity, structuring, non‐intrusiveness, non‐hostility, and children's responsiveness to, and involvement of, mothers. We additionally coded children's over‐responsiveness and over‐involvement. Using person‐centred analyses, we identified four clusters: high functioning, low functioning, asynchronous (mothers above average on two of four dimensions and children below), and below average. Mothers in the low‐functioning cluster had lower income, less social support, more of the borderline feature of negative relationships, and more depression than did mothers in the high‐functioning cluster. The children in the low‐functioning group had more risk factors for BPD (physical abuse, neglect, and separation from, or loss of caregivers, and negative narrative representations of the mother–child relationship in their stories) than did children in the high‐functioning group. The asynchronous group included older girls who were over‐responsive and over‐involving with their mothers in an apparent role reversal. Interventions targeting emotional availability may provide a buffer for children facing cumulative risks and help prevent psychopathology.

Highlights

  • This paper investigated how mother‐child emotional availability (warmth and closeness) relates to risk factors for borderline personality disorder, including mother‐child role reversal.
  • In filmed mother‐child interactions, low emotional availability was associated with risk for borderline personality disorder and role reversal was more likely for older girls.
  • Findings support the cumulative risk hypothesis and may inform interventions to improve mother‐child emotional availability to prevent the development of psychopathology.

Despite all the information about the risks, many people still smoke. Several studies investigated risk perceptions in smokers. The adequate perceptions of the risks from smoking is particularly important and this study investigated the risk perception of young smokers vs non-smokers by a new time-estimation task in which we required participants (smokers and non-smokers) to estimate the onset time of smoking-related conditions in an average young smoker. The findings supported our main hypothesis that smokers, compared to non-smokers, postponed the onset of both mild and severe smoking-related conditions. The results also revealed that the onset time estimates for mild conditions given by both smokers and non-smokers were associated with their self-perceptions of risk and level of fear of developing smoking-related conditions. The findings cast light on smokers’ distorted temporal perception of the health-damaging consequences of smoking. Implications for the adequacy of risk perception in smokers are discussed.  相似文献

本研究在验证成就动机对风险决策倾向的预测作用的基础上,进一步探索情绪在成就动机和风险决策关系中的调节效应。通过对三所学校随机抽取的150名被试进行筛选,采用成就动机量表和自编风险决策任务问卷等对120名有效被试实施问卷调查。结果发现:情绪启动使大学生风险决策行为产生一致性效应,即心境一致性;情绪在成就动机和风险决策中起到了一定的调节作用,无论是高成就动机者还是低成就动机者,在愉悦情绪下都表现出更多的风险寻求倾向,并达到了极其显著的水平,而在悲伤情绪下,低成就动机者表现出更多的风险规避,高成就动机者的风险规避倾向虽有所增加,但并未达到显著水平。  相似文献

This paper explores the discursive construction of immigrants' criminality in interview accounts obtained by a sample of Greek people in Thessaloniki (Northern Greece). Analysis, which adopts a discursive approach to stereotypes and category construction, indicates that fear and insecurity on the part of Greek people are represented as a sine qua non consequence of immigration to Greece. Two different lines of argument are used to account for the arousal of fear. According to the first, fear constitutes a corollary of a widespread stereotypical representation of immigrants as criminals. The stereotype of immigrants' criminality is considered to be ill‐warranted and it is attributed to the media or to other unspecified people. According to another, more regularly used, line of argument, however, fear is predicated upon the sordid living conditions of immigrants in Greece which make the probability of them being involved in illegal acts particularly high. In this case, fear is seen to derive from a ‘rational estimate’ of the probability of immigrant's involvement in criminal acts. Nested within the discourse of ‘risk’ the stereotypical image of immigrants' criminality is sustained and used to account for the need to protect the ‘ingroup’ from ‘immigrant groups’ through immigration control and surveillance.

气候变化已经成为全球面临的最紧迫问题之一。近期研究发现,个体对于气候变化风险的元认知和其亲环境行为之间关系密切。对元认知知识、元认知来源、元认知确定性及元认知重要性四个维度相关研究的分析表明,公众元认知知识与实际知识的偏离、以分析系统为主导的风险认知来源、对气候变化后果确定性的低估以及对气候变化重要性的忽视都会抑制环境友好行为的发生,并指出了气候变化风险元认知研究的未来趋势。  相似文献

Senior drivers are vulnerable to automobile crashes and subsequent injury and death. Safety belts reduce health risks associated with auto crashes. Therefore, it is important to encourage senior drivers to wear safety belts while driving. Using an AB design, replicated five times, we evaluated the short- and long-term effects of a sign with the message "BUCKLE UP, STAY SAFE" attached to a stop sign at the exits of five different senior communities. Safety belt use was stable during two pretreatment assessments averaged across the five sites and 250 drivers (72% and 68% usage), but significantly increased following installation of these signs (94% usage). Six months after installation of the signs, the effect persisted (88% usage). Use of such signs may be a cost-effective way of promoting safety belt use.  相似文献

Preschool boys' emotional displays during conflicts with mixed-sex peers were related to individual differences in peer sociometric status and teacher ratings of disruptive behavior. Participants were 60 4- to 5-year old boys from low-income families who were videotaped with a small group of classmates in a Head Start preschool classroom. Conflicts were identified and emotional displays were coded from videotape. Results indicated that conflicts were more negative in emotional tone at the end than at the beginning of the year. Furthermore, children tended to mirror each others' emotional displays at the end but not the beginning of the preschool year. In addition, gleeful taunting, a form of emotional aggression, more strongly predicted negative peer nominations and teacher ratings than anger, suggesting that anger may be a more socially accepted form of emotional expression during conflicts among preschool-age children. Implications and directions for future research and interventions are discussed.  相似文献
