This article reports on an anthropological investigation of the social impact and cultural meaning of amniocentesis conducted in New York City, illustrating how class differences, as well as sociocultural diversity, deeply affect pregnant women's acceptance, rejection, and interpretation of prenatal testing. The article also suggests the importance of recognizing how counselors' cultural backgrounds and styles affect patient-counselor communications. 相似文献

Twenty-six infants, 3 to 23 months old, were trained on fixed-interval schedules ranging from 10 s to 80 s. The operant response was touching an illuminated location on a touch-sensitive screen, and 20 s of cartoon presentation was the reinforcer. The subjects were also trained in a six-phase self-control procedure in which the critical phases involved choice between 20 s of cartoon available after a 0.5-s delay (impulsive choice) and 40 s of cartoon delayed for 40 s (self-controlled choice). All the youngest children (3 to 5 months) showed long postreinforcement pauses on the fixed-interval schedule, with most intervals involving the emission of a single, reinforced, response, and all made self-controlled choices. Older subjects (9 to 23 months) either produced the same pattern as the younger ones on the fixed-interval schedule (classified as pause-sensitive subjects) or produced short pauses and higher steady response rates (classified as pause-insensitive subjects). All pause-sensitive subjects made self-controlled choices in the self-control condition, and all pause-insensitive subjects made impulsive ones. 相似文献

Genetic counseling for women of advanced maternal age who are considering prenatal testing continues to be based on a principle of nondirectiveness. We interviewed 11 genetic counseling students and four counselors about how they experience and manage, in practice, the tensions between the ideology of nondirectiveness and the acknowledged reality that one can never be truly nondirective. We found that our respondents creatively resolve this tension—simultaneously resisting and adhering to the values of nondirectiveness and information-giving—in individual and situation-specific ways. This resolution is facilitated by the extent to which information given to counselees is fluid, mobile and context-dependent, but these very features of information also have critical implications for both the norms and the practice of genetic counseling. 相似文献

Previous studies have shown that unexplained deviations in maternal serum multiple marker screening (MMS) generate considerable anxiety during the remainder of pregnancy. While the role of education in decreasing anxiety is documented, to date there has been no prospective evaluation of which educational practices might minimize this emotional stress. In a pilot study, we prospectively examined the effects on anxiety and knowledge by providing information about MMS (1) by genetic counselor, (2) by pamphlet, and (3) by primary physician. Women randomized to one of these three modalities were administered the Spielberger State- Trait Anxiety Inventory [STAI] and knowledge questionnaires at their initial obstetrics visit, at their second visit after educational intervention and 1–2 weeks after MMS results were provided to patients. Education resulted in an increase in knowledge and post-education knowledge was different between educational modalities. Anxiety declined in patients educated through genetic counseling or a pamphlet. 相似文献

A mailed survey of female prenatal genetic counselors, obstetric nurses, and high school biology teachers was conducted to determine if these groups hold different attitudes toward genetic risk and to investigate the extent to which any differences result from the effect of different professional experiences. In this study, the participants were 166 genetic counselors, 116 obstetric nurses, and 78 biology teachers (n = 360). Survey participants completed a written questionnaire designed to assess their numeric estimate of the empiric risk for birth defects/genetic problems, their subjective perception of this risk, and their personal use of prenatal diagnosis. Genetic counselors were found to be less likely than the other groups to consider the frequency of birth defects/genetic problems as rare and were 10 times more likely than nurses and 8 times more likely than teachers to have had prenatal diagnosis. Furthermore, more than half of the prenatal diagnosis procedures had by genetic counselors were not medically indicated. These results suggest that genetic counselors have an increased perception of genetic risks relative to nurses or teachers. Possible explanations for this finding are discussed, and the potential role of discordant risk perception in creating biases in the genetic counseling process is explored. 相似文献
