We defined and measured a dimension of religiosity frequently invoked in end-of-life (EOL) research—deference to God’s Will (GW)—and examined its relationship to preferences for life-prolonging treatments. In a 35-min telephone interview, 304 older men and women (60 +) were administered the 5-item GW scale, sociodemographic questions, three attitude items regarding length of life, and measures of two health indices, depression, and life-prolonging treatment preferences. The GW scale demonstrated internal consistency (Cronbach’s alpha = .94) and predictive and discriminant validity. Higher scores indicative of greater deference to GW were associated with stronger life-prolonging treatment preferences in poor-prognosis scenarios. Implications for the role of religiosity in medical decision-making are discussed.  相似文献

We evaluated a multiple‐stimulus assessment for identifying work preferences among adults with autism prior to beginning supported jobs. Initially, a prework assessment focused on identifying preferences across different work tasks. Eight preference assessments involving office‐cleaning tasks were conducted with five supported workers. Results of five assessments involving three individuals indicated respective workers had a strong preference for one work task. On three assessments involving three workers and different cleaning tasks, weak preferences for given tasks were identified. Next, choices between more‐ and less‐preferred tasks were provided during the daily job routine. Workers who had a strong preference on the prework assessment consistently chose the previously assessed, more preferred task during the daily job. Workers who had a weak preference always chose the more preferred task on the first choice of the work day, and then alternated between tasks on 71% of subsequent choice opportunities. Results appear to support the utility of the prework, multiple‐stimulus assessment for predicting preferred tasks among supported workers with autism when the assessment identifies strong preferences. Results also offer some support for predicting a preference to alternate tasks when the assessment identifies weak preferences for respective work tasks. Implications of the results are discussed in terms of developing work routines within community jobs for adults with autism that are more in accordance with their work preferences than traditional job placement practices.

The present study examined whether a set of demographic variables and stereotype threat could explain African-American/White mean differences in cognitive ability test performance. African Americans and Whites were found to significantly differ in stereotype threat and educational attainment of participants' fathers (i.e., father education). In moderate support of our study hypothesis, stereotype threat and father education partially mediated race differences in cognitive ability test scores. Implications for study findings are discussed, and limitations of the study are noted.  相似文献

Understanding the possible causes of differences in intelligence is crucial if children are to achieve their full potential. Such understanding has been hampered until recently, however, because researchers who study intelligence have neglected recent findings in the brain sciences suggesting that the brain develops in response to environmental stimulation. These findings have seemed to contradict intelligence research that suggests that intellectual abilities are inherited. However, the findings from intelligence research and the brain sciences can be integrated if it is accepted that there are individual differences in the process by which the brain adapts to the environment, such that some people's brains are better at adapting than others'. The findings obtained from intelligence research are consistent with this integrated model. Such an integration has implications for better understanding the nature of intelligence.  相似文献

For this content analysis we recorded a sample of 1,337 prime time commercials from the 3 major networks (ABC, CBS, and NBC) in 1998. There were 5,473 primary and secondary characters identified. Each character was coded for gender, age, acting role, and product being advertised. The findings were then compared to Bretl and Cantor (1988), the U.S. Census Bureau's 2000 population statistics, and Mediamark Research and Simmons syndicated marketing services. The commercials' producers cast their female and male characters much the same way as was done in the 1980s. Although women make most purchases of goods and services, they are still underrepresented as primary characters during most prime time commercials except for health and beauty products. Women are still cast as younger, supportive counterparts to men, and older women are still the most underrepresented group. Television commercials perpetuate traditional stereotypes of women and men.  相似文献

Prison inmates have high prevalence rates for both HIV and AIDS, creating a great need for HIV prevention efforts. We tested the theory of planned behavior (TPB) in 3 domains: intention to engage in condom use when released, intention to not share tattoo equipment in prison, and intention to not share needles or tattoo equipment when released. A total of 478 inmates (87% male) completed TPB and sexual and needle‐use risk behavior measures. TPB constructs accounted for a significant variance in intention to use condoms among African American, Hispanic, and Caucasian inmates, though the strength of the relationships differed by ethnicity. The TPB was less successful for intention to share tattooing equipment and not to share needles or tattoo equipment after release.  相似文献

As part of its evolving notions of self, contemporary Western culture has come to regard integrity as a preeminent public and private virtue. The meanings now given to integrity appear to cluster around its form, which is personal coherence, and its content, which is standing for something important. Building on Stephen Carter's explication of integrity, and in response to its veneration as a moral panacea, three limitations of integrity are discussed. First, integrity does not guarantee that right and wrong have actually been discerned, only that an attempt has been made, that moral reflection has occurred. Second, integrity does not necessarily engender or even preserve interpersonal peace, but instead frequently causes conflict it is then unable to resolve. Third, integrity does not always precipitate or prevent the reform of social structures and organizations, because it remains subject to the exercise of interpersonal power.  相似文献

Students are often uncertain and at times misinformed about the careers they are pursuing. Thus, they often make poor career decisions that they ultimately regret. The career wheel exercise is designed to help an individual to be better informed and thus make better career‐related decisions. This article describes the career wheel exercise, which is an active career exploration device. Through this exercise, students validate or invalidate their beliefs and assumptions about the careers they are actively pursuing or contemplating. Thus, they are able to make a more informed career and job choice.  相似文献

The Beliefs About Medication Scale: Development, Reliability, and Validity   总被引:4,自引:0,他引:4  
The purpose of the study was to develop and evaluate a psychometrically sound health belief measure, the Beliefs About Medication Scale (BAMS) that can be used with adolescent chronic illness populations whose prescribed treatment includes oral medication. One hundred and thirty-three adolescents (age 11–18 years) with asthma (n = 60), HIV (n = 31), or inflammatory bowel disease (n = 42) completed the BAMS and, along with their parent, a self-report medication interview. A confirmatory factor analysis supported the hypothesized subscales of Perceived Threat, Positive Outcome Expectancy, Negative Outcome Expectancy, and Intent to Adhere to treatment. The subscales evidenced good internal consistency and 3-week test-retest reliability. Univariate and multivariate analyses demonstrated that the health belief constructs accounted for 22% of the variance in medication adherence beyond demographic and illness characteristics. The study provides preliminary evidence of the reliability and validity of a theoretically based measure of health beliefs for adolescents. The BAMS may be a useful tool to evaluate the psychological barriers to adherence that place teenagers at risk for nonadherence.  相似文献

This study investigated coping resources (Coping Resources Inventory for Stress), perceived stress (Perceived Stress Scale), and life satisfaction (Satisfaction with Life Scale) among American and Turkish university students. Results support the use of transactional stress constructs in studying life satisfaction with students in both countries. American and Turkish students did not differ significantly in regard to perceived stress, life satisfaction, or an overall measure of coping resources; however, they did differ significantly regarding specific coping resources. Variables entering regression models for predicting life satisfaction differed for students in the two countries and for the sexes within countries, and these models accounted for between 30% and 62% of variance. Social support and a sense of financial freedom were particularly useful in predicting life satisfaction. Coping resources accounted for 54% of variance in perceived stress. There were significant sex differences for both countries, generally favoring males, in regard to specific coping resources.  相似文献
