Genetic counselors believe fertility preservation and preimplantation genetic diagnosis (PGD) discussions to be a part of their role when counseling BRCA1/2 mutation-positive patients. This study is the first to explore reproductive endocrinologists’ (REI) practices and attitudes regarding involvement of genetic counselors in the care of BRCA1/2 mutation carriers seeking fertility preservation and PGD. A survey was mailed to 1000 REIs from Reproductive Endocrinology & Infertility (SREI), an American Society for Reproductive Medicine (ASRM) affiliate group. A 14.5 % response rate was achieved; data was analyzed using SPSS software. The majority of participating REIs were found to recommend genetic counseling to cancer patients considering fertility preservation (82 %) and consult with a genetic counselor regarding PGD for hereditary cancer syndromes (92 %). Additionally, REIs consult genetic counselors regarding PGD patient counseling (88 %), genetic testing (78 %), and general genetics questions (66 %). Two areas genetic counselors may further aid REIs are: elicitation of family history, which is useful to determine fertility preservation and PGD intervention timing (32 % of REIs utilize a cancer family history to determine intervention timing); and, interpretation of variants of uncertain significance (VOUS) as cancer panel genetic testing becomes more common (36 % of REIs are unfamiliar with VOUS). Given our findings, the Oncofertility Consortium® created an online resource for genetic counselors focused on fertility preservation education and communication strategies.  相似文献

The present study investigated relationships between dimensions of anxiety, age, gender, and school adjustment in students with specific learning disabilities (SLD). The 177 students with SLD completed measures of anxiety and school adjustment. The results of a hierarchical regression analysis indicated that age and gender together were not significant predictors of attitude to school, and that after the influence of age and gender had been removed students with more physiological and social anxiety, but less worry tended to have poorer attitudes toward school. A second hierarchical regression indicated that younger students reported more negative attitudes toward teachers, and after controlling for age and gender, students with more social anxiety reported more negative attitudes toward teachers. Implications for school personnel are discussed.  相似文献

We conducted a primary study and a meta-analysis on the relation of trait subordination measures to trait measures of sensitivity to nonverbal cues, in order to test the hypothesis that more subordinate individuals have enhanced ability to decode nonverbal cues. In the primary study, subordination measures included socioeconomic background, two dominance scales, a capacity for status scale, a control by powerful others scale, self-ratings of leadership and social status in high school, and for women, measures of sex role values. Sensitivity to nonverbal cues was measured using three psychometric tests, Results showed little overall support for the subordination hypothesis, and some results were significantly opposite to the prediction. The meta-analysis showed that dominance, capacity for status, socioeconomic status, and women's sex role values all had relations to nonverbal sensitivity that were opposite to the predictions of the subordination hypothesis. Future prospects for the subordination hypothesis with respect to nonverbal sensitivity are discussed.  相似文献

Abstract— The relation between accuracy and distortion of autobiographical memory content was examined by verifying 3,220 high school grades recalled by 99 college students. Accuracy of recall declined monotonically with letter grade, from 89% for grades of A to 29% for grades of D. The positive correlation between achievement and accuracy of recall is attributed to more frequent rehearsals of affectively positive content and to greater accuracy of reconstructive inferences based on homogeneous, generic memories. Most errors inflated the verified grade, and the degree of asymmetry of the error distribution is used as an index of the degree of distortion. Distortions are attributed to reconstructions in a positive, emotionally gratifying direction. Contrary to expectation, the percentage of accurate recall and the degree of asymmetry of the error distribution were uncorrelated. This finding indicates that the process of distortion does not cause forgetting of the veridical content Rather, distortion reflects bias in reconstructive inferences that occur after the veridical content has been forgotten for other reasons  相似文献

We investigated the frame of reference that people use to make shape discriminations when their heads are either upright or tilted. Observers madesame-different judgments of pairs of novel threedimensional objects that were aligned along their length within the frontal-parallel plane and rotated in depth around an axis parallel to their own axes of elongation. The aligned objects were displayed vertically, tilted 45°, or horizontally with respect to the environmental upright, but the distance of each pair from the upright was irrelevant to resolving the angular disparity between the stimuli for thesame-different judgment. Nevertheless, when observers’ heads were upright, the time to encode the stimuli was a linear function of the distance of the stimuli from the environmental upright, whereas when observers’ heads were tilted 45°, encoding times for tilted and vertical stimuli did not differ and were faster than the times to encode horizontal stimuli. We interpreted these data to mean that observers either rotate or reference the top of an object to the environmental upright, and they can use either a gravitational or retinal reference frame to do so when either they or the objects are not upright.  相似文献

A questionnaire was designed which enquired into the long-term professional applications and outcomes of Rogerian small-group and Tavistock Group Dynamics training. The 92 respondents were graduates of either a Master's degree or a Diploma in Human Relations or Counselling Studies in a university course where a 'small-group' module was a compulsory element of the taught course. Respondents were drawn from graduates of these one-year full-time or two-year part-time courses over a 21-year period. All respondents were involved either directly in professional or voluntary counselling, in the application of counselling skills in their work, or in training in counselling and counselling skills at work. The respondents reported no loss of learning gains over time: ascribed the application of many specific counselling skills to the small-group training process; reported on the affective component of the learning process; and provided only minimal evidence of forms of psychological damage which could be directly ascribed to the experience. These outcomes have to be considered in the light of the relatively low response rate of 33% and the difficulties in monitoring the precise behaviour of the facilitators in the groups.  相似文献

Indirect instructional approaches, such as responsive interaction, are common in inclusive early childhood settings. Unfortunately, young children with disabilities do not always have the skills to take advantage of these learning opportunities. Teaching children with disabilities to be more responsive to developmentally appropriate indirect instructional strategies may help them take advantage of and benefit from available learning opportunities in inclusive settings. The purpose of this research was to examine the extent to which presenting a series of direct questions increased children's attempts to respond and correct responses to indirect requests. Increased attempts to respond and correct responses to indirect requests were evident for all participants with whom the intervention was implemented. Three of the participants continued to attempt to respond and responded correctly to indirect requests when intervention procedures were removed. The contributions of these findings to literature on language instruction with young children, implications of the findings for practitioners, methodological limitations, and suggestions for future research are discussed.  相似文献
