Through school-sponsored health fairs, 398 adolescents (153 males and 245 females) between the ages of 14 and 18 completed a questionnaire on their compliance with six of the U.S. Dietary Guidelines. Results indicated that adolescents report highest compliance on "eat a variety of foods" and "eat foods with adequate starch and fiber." Conversely, they indicated low compliance on "reduce sugar intake" and "reduce fat, saturated fat and cholesterol intake." Sex differences were noted on two dietary guidelines. Females reported lower compliance with respect to "maintain desirable body weight." Males, on the other hand, reported lower compliance than females on "reduce salt intake." Given the fact that the dietary guidelines of "reduce fat, saturated fat and cholesterol," "maintain desirable body weight," and "reduce salt intake" are all aimed at reducing cardiovascular risk, the low compliance reported by adolescents may have long-range health implications.  相似文献

This article examines the question of how the lack of differences in general self-esteem between adolescents of ethnic minorities and Dutch adolescents can be explained. Attention is focused on the reflected appraisal process. It was found that for adolescents of ethnic minorities there is a significant relationship between general self-esteem and the perceived evaluation of family members, and no such relationship with nonfamily members. For the Dutch adolescents the findings are the opposite, which may explain why adolescents of ethnic minorities in general do not have lower general self-esteem, despite low status, prejudice, and discrimination.  相似文献

Forgiveness is commended by Christianity, as well as other religious traditions, as one of the most central of virtues, so central that the New Testament links man's very salvation to his ability to forgive. However, mental health professionals have correctly pointed out that the mandate to forgive is often used by religious patients in the service of defenses such as reaction formation, undoing, and denial. The forgiveness ideal is often misunderstood as a command not to experience aggressive feelings.It is the thesis of this paper that the capacity for genuine forgiveness is central not only to spiritual development but to psychological development as well. It is suggested that Kernberg's object relations theory provides the best model for understanding the nature and importance of forgiveness. Mature forgiveness does not involve the elimination of negative feelings toward others (or oneself) but the integration of negative and positive self-object representations and their connected affect. Anger at the offending persons must then be tempered by appreciation for their concomitant good qualities and motivations or, at the very least, empathy for the flaws which prompted them to behave destructively. The result is a more realistic and balanced view of others (and oneself), a more genuine relationship to the full range of one's own inner experience, and a greater ability to respond constructively to frustrating persons and situations.This paper was presented at the Annual Meeting of the American Psychological Association in New York in August 1987. The author wishes to thank Mark Finn, Ph.D., and David Hamblin, Ph.D., for their valuable discussions in the development of the ideas in the paper. Address requests for reprints to Dr. Gartner, Dept. of Pastoral Counseling, Loyola College, 7135 Mistrel Way, Columbia, MD 21045.  相似文献

The care of the patient with cancer requires the development not only of a medical plan, but an ethical plan as well. This plan should integrate the physician's and the patient's perceptions of medical and ethical propriety. Jewish biomedical ethical principles are based on the teaching of the Old Testament and its various interpretations. In this paper, I discuss how these principles can be used to help guide the physician caring for the patient with cancer. Other ethical systems could be applied in a similar fashion.  相似文献

Survey respondents may inaccurately report mental health service utilization for motivational and cognitive reasons. There is little evidence on accuracy of self-reports of mental health service use, and this evidence suggests that respondents tend to underreport inpatient utilization. This study addressed the question of self-report accuracy by comparing survey data from a large probability sample to data from computerized records of publicly funded mental health services. Few inaccuracies in self-reporting were detected. However, despite the use of data bases that were unusually appropriate for verifying self-reports, several problems limited the feasibility of validation. Suggestions are offered for increasing the feasibility of validation in future studies.  相似文献
