This study investigated moderators of newlywed spouses' accuracy in judging each other's personality. Spouses in 154 predominantly Hispanic newlywed couples rated their own and their partners' personality traits. Full‐sample results showed significant associations between perceivers' and targets' personality ratings (“truth force”/“tracking accuracy”). Positive directional bias (perceivers' mean trait ratings of targets exceeding targets' self‐ratings) also was evident. Positive directional bias occurred when perceivers had little familiarity with their spouse prior to dating and when perceivers had high self‐esteem. Truth force/tracking accuracy increased with less time spent cohabiting and higher perceiver self‐esteem. Positive associations between perceivers' self‐esteem and ratings of partners on positively valenced traits were reduced when partners had had greater opportunities to observe one another's behaviors. 相似文献

Professional pharmaceutical services may impact on patient’s health behaviour as well as influence on patients’ perceptions of the pharmacist image. The Health Belief Model predicts health-related behaviours using patients’ beliefs. However, health beliefs (HBs) could transcend beyond predicting health behaviour and may have an impact on the patients’ perceptions of the pharmacist image. This study objective was to develop and test a model that relates patients’ HBs to patient’s perception of the image of the pharmacist, and to assess if the provision of pharmacy services (Intervention group-IG) influences this perception compared to usual care (Control group). A qualitative study was undertaken and a questionnaire was created for the development of the model. The content, dimensions, validity and reliability of the questionnaire were pre-tested qualitatively and in a pilot mail survey. The reliability and validity of the proposed model were tested using Confirmatory Factor Analysis (CFA). Structural Equation Modelling (SEM) was used to explain relationships between dimensions of the final model and to analyse differences between groups. As a result, a final model was developed. CFA concluded that the model was valid and reliable (Goodness of Fit indices: x²(80) = 125.726, p = .001, RMSEA = .04, SRMR = .04, GFI = .997, NFI = .93, CFI = .974). SEM indicated that ‘Perceived benefits’ were significantly associated with ‘Perceived Pharmacist Image’ in the whole sample. Differences were found in the IG with also ‘Self-efficacy’ significantly influencing ‘Perceived pharmacist image’. A model of patients’ HBs related to their image of the pharmacist was developed and tested. When pharmacists deliver professional services, these services modify some patients’ HBs that in turn influence public perception of the pharmacist. 相似文献

Can bilingual exposure impact children's neural circuitry for learning to read? To answer this question, we investigated the brain bases of morphological awareness, one of the key spoken language abilities for learning to read in English and Chinese. Bilingual Chinese‐English and monolingual English children (N = 22, ages 7–12) completed morphological tasks that best characterize each of their languages: compound morphology in Chinese (e.g. basket + ball = basketball) and derivational morphology in English (e.g. re + do = redo). In contrast to monolinguals, bilinguals showed greater activation in the left middle temporal region, suggesting that bilingual exposure to Chinese impacts the functionality of brain regions supporting semantic abilities. Similar to monolinguals, bilinguals showed greater activation in the left inferior frontal region [BA 45] in English than Chinese, suggesting that young bilinguals form language‐specific neural representations. The findings offer new insights to inform bilingual and cross‐linguistic models of language and literacy acquisition. 相似文献

Parental Stress and Children’s Social and Behavioral Outcomes: The Role of Abuse Potential over Time
Parental stress is a well-established risk factor for adverse child outcomes, including the development of aggression, externalizing behavior problems, and anxiety, as well as compromised emotional coping, impaired social cognition, and diminished treatment response. Abuse potential represents a mechanism by which parental stress may impact child social competence and behavior; evidence links parental stress to abuse potential, and abuse potential to a range of negative child social competence and behavioral outcomes. The current study assessed relationships between parental stress, abuse potential, and child social and behavioral outcomes over time. Parents of children ages 2–6 years (N?=?610, 44% girls) reported on perceived parental stress and attitudes towards abuse and neglect, as well as child social competence and behavior problems, before and after a caregiver-directed, community-based intervention. Changes in parental stress, abuse potential, and child social and behavioral outcomes were examined using panel analyses, while controlling for intervention effects and demographic variables. Parental stress predicted child social competence, anxiety/withdrawal, and anger/aggression over time; while the links between stress and anxiety/withdrawal, and stress and social competence, were mediated by child abuse potential, the link between stress and anger/aggression was not mediated by child abuse potential. Findings suggest that abuse potential represents a mechanism by which parental stress and child social and behavioral outcomes are linked. Further, screening for child social competence deficits may identify children at risk for abuse, as well as parents in need of services to reduce stress. 相似文献

Using the German Socio-Economic Panel, we analyze the relevance of modeling social comparisons to determine their effect on subjective well-being. We find that it is important to model social comparisons in such a way that captures the sensitivity of individuals to proximity. The impact on subjective well-being differs depending on the manner in which proximity is modeled, revealing that the underlying processes in comparisons are not homogenous along the income distribution. Additionally, our results point out that social and cultural capital modify the effect of social comparisons and such modification depends on the sensitivity to proximity. 相似文献

The present study sought to investigate how alexithymia (a deficit in identifying and describing emotions) may hinder the development of posttraumatic growth (PTG) and contribute to ongoing distress. Participants were 250 undergraduate college students who had experienced a highly stressful event in the past six months. Regression analyses were conducted to examine how alexithymia contributes to PTG and distress in addition to other known predictors. Analyses revealed that alexithymia was a significant negative predictor of PTG, and a significant positive predictor of distress. It was also found that Difficulty in Identifying Feelings was the alexithymia component that best predicted PTG and distress. 相似文献

Much of the fear and uncertainty around Zika epidemics stem from potential association between Zika virus (ZIKV) complications on infected pregnant women and risk of their babies being born with microcephaly and other neurological abnormalities. However, much remains unknown about its mode of transmission, diagnosis and long-term pathogenesis. Worries of these unknowns necessitate the need for effective and efficient psychosocial programs and medical-legal strategies to alleviate and mitigate ZIKV related burdens. In this light, local and global efforts in maintaining fundamental health principles of moral, medical and legal decision-making policies, and interventions to preserve and promote individual and collectiveHuman Rights, autonomy, protection of the most vulnerable, equity, dignity, integrity and beneficence that should not be confused and relegated by compassionate humanitarian assistance and support. This paper explores the potential medical and ethical-legal implications of ZIKV epidemics emergency response packages and strategies alongside optimizing reproductive and mental health policies, programs and best practice measures. Further long-term cross-borders operational research is required in elucidating Zika-related population-based epidemiology, ethical-medical and societal implications in guiding evidence-based local and global ZIKV maternal-child health complications related approaches and interventions. Core programs and interventions including future Zika safe and effective vaccines for global Zika immunization program in most vulnerable and affected countries and worldwide should be prioritized. 相似文献
