家庭社会经济地位对初中生阅读成就的影响：阅读动机和阅读活动的中介作用

为探讨阅读动机和阅读活动在家庭社会经济地位与阅读成就关系之间的中介机制,采用问卷法对我国东部某省3所学校468名7～9年级学生进行调查,使用结构方程建模的方法对中介模型进行检验。结果表明：家庭社会经济地位、阅读动机、阅读活动及阅读成就之间呈显著正相关;家庭社会经济地位对阅读成就的直接效应不显著,但可以通过阅读动机和阅读活动的链式中介作用对阅读成就产生间接的影响。     

Body dissatisfaction and body change behaviors in Chile: the role of sociocultural factors

With interest in body image and body change behaviors growing around the world, there has been surprisingly little research conducted in Latin America on these issues. In order to gain some understanding of them in this context, this study investigated body image and body change behaviors, and the sociocultural factors that may influence them, among 337 Chilean adolescents aged 12–18 years. Participants completed a questionnaire that assessed BMI, body dissatisfaction, strategies to lose weight and strategies to increase muscle bulk. In addition, perceived pressure from family, peers, and the media to change body shape was evaluated. Results were partially consistent with those reported in Western nations. Girls were found to report greater body dissatisfaction than boys, but no difference was found between males and females in perceived pressure from adults in the family or from older siblings/cousins to lose weight. However, girls experienced higher levels of perceived pressure to lose weight from the media than boys, and boys reported greater perceived pressure from peers to lose weight than girls, and more pressure than girls from all sources to increase muscle bulk. These findings are discussed in relation to research conducted in other contexts, and it is concluded that findings from other locations may not be applied universally.     

Weight concerns among elementary school children: a review of prevention programs

There is increasing evidence that children display high levels of weight and muscle concerns, which include body dissatisfaction and problem eating. In order to address these issues, researchers have designed and implemented prevention programs for this age group. Thirteen published studies were located and reviewed, with children aged 8-12 years from elementary schools, or equivalent. Overall, the programs were shown to be effective in improving children's knowledge at post-test and at follow-up assessments. However, there is limited evidence to show that the programs reduced or prevented body image concerns and/or problem eating. Too few studies have examined muscle concerns so no conclusions can yet be drawn about this domain. Limitations of the studies and suggestions for future prevention efforts are discussed.     

Appearance-based comments, body dissatisfaction and drive for muscularity in males

This study examined the role of positive and negative appearance-based comments on body dissatisfaction and drive for muscularity among young adult males. The direct and moderating effect of self-esteem were also investigated; and BMI, age, and social desirability were included as covariates. The participants were 214 males aged between 18 and 30 years. More frequent negative comments were associated with higher body dissatisfaction whilst more frequent positive comments were associated with lower body dissatisfaction. However, both frequent negative and positive commentary were associated with higher drive for muscularity. Self-esteem was also associated with both body dissatisfaction and the drive for muscularity, but it did not moderate that influence of either positive or negative messages. Longitudinal research is now needed to determine the directionality of these relationships. Further research is required to establish the contexts in which positive and negative messages are associated with body dissatisfaction and the drive for muscularity.     

Body Image and Self-Esteem Across Age and Gender: A Short-Term Longitudinal Study

This study examined the relationship between body image and self-esteem across time and age for men and women. Participants were 150 men and 239 women aged between 20 and 86 years (M?=?59.73), recruited from the general population in Australia. They completed a questionnaire assessing self-esteem, body dissatisfaction, body importance, and a range of other domains of life satisfaction at baseline and 2 years later. Cross-sectionally, we found that higher self-esteem was associated with lower body dissatisfaction, but there was no consistent relationship between these variables across time for age and gender. Women were more dissatisfied with their bodies than men; yet, men placed greater importance on their appearance than women, and also reported high levels of body dissatisfaction.     

Interest and Beliefs About BRCA Genetic Counseling Among At-Risk Latinas in New York City

Background: Latinas are less likely to use genetic services (counseling and testing) for hereditary breast and/or ovarian cancer risk compared to other ethnic groups. Meanwhile, little is known about barriers to genetic counseling among Latinas at increased risk of inherited breast cancer. Methods: A two-phase pilot study was conducted to examine interest, barriers and beliefs about BRCA genetic counseling among at-risk Latinas in New York City and explore the potential for developing a culturally-tailored narrative educational tool for use in future studies. Phase 1 included quantitative telephone interviews (N = 15) with bilingual participants with a personal diagnosis at a young age and/or family history of breast and/or ovarian cancer. Quantitative results informed development of a narrative prototype educational presentation viewed by a subset of participants (N = 10) in Phase 2 focus groups. Results: Despite barriers, including lack of awareness/knowledge, concerns related to learning cancer risks of family members, and concerns about cost/health insurance, participants reported positive attitudes, beliefs and interest in learning about BRCA genetic counseling. Further, significant increases in knowledge were demonstrated from pre-post presentation (p = 0.04). Conclusion: There is an unmet need to educate at-risk Latinas about BRCA genetic counseling. Culturally-tailored educational materials including narratives may increase knowledge about BRCA genetic counseling among this underserved group. The effectiveness of these approaches should be tested in future research with larger samples.     

更优更耐心：质量结果对跨期选择的影响

跨期选择以往的研究集中于金钱数量结果。基于维度加工的模型,本文探究了在跨期选择中,人们面对质量差异的结果（如今天的低配版手机还是六个月后的高配版手机）与相对应的金钱结果（如今天的5000元还是六个月后的6000元）的选择偏好差异。三个实验结果表明：人们面对质量结果（相比于金钱结果）的跨期选择表现得更耐心,而这种现象是由于人们面对选择时在结果维度差异感知不同所致。与金钱结果跨期选择相同,质量结果跨期选择的心理加工过程同样遵循维度间差异比较。本研究为基于维度的跨期选择模型提供了新的证据。     

Desirable and undesirable gender traits in three behavioral domains

The present study investigated the factorial validity of a four-factor model of gender stereotypes in 888 subjects (97% Anglo-Australian Caucasian). The scale reflected the constructs desirable masculinity, desirable femininity, undesirable masculinity and undesirable femininity. LISREL analyses showed that this four-factor model fitted the data better than either a two-factor model consisting of overall masculinity and femininity or an one-factor bipolar model. Furthermore, the study highlights the utility of studying both desirable and undesirable gender traits as they generally predicted different behaviors for males and females.
