Of 1,053 medical geneticists in 18 nations 677 (64%) returned questionnaires on their views on the importance of seven goals of genetic counseling, the appropriateness of five directive/nondirective approaches to counseling, and their choices of action in four situations involving directive/nondirective counseling. The majority (92%-94%) regarded nondirective approaches as appropriate; their views on both goals and approaches were similar to those reported in an earlier survey of 205 genetic counselors in the United States. In clinical situations involving presentation of reproductive options to carriers of disorders not diagnosable prenatally, 74%-85% would present contraception, sterilization, taking one's chances, artificial insemination donor (AID), or adoption as options even if not asked; 66% would present in vitro fertilization (IVF) with a donor egg; and 46% (67% in the United States) would present surrogate motherhood. In regard to three situations involving fetuses with low-burden disorders (Turner syndrome, XYY, and a possible small neural tube defect), 84%-88% would counsel nondirectively. Stepwise logistic regression analyses on professional and personal background variables showed that gender was related, cross-nationally, to self-reported directiveness in counseling, with men more likely than women to regard directive approaches as appropriate, more likely to give advice about fetuses with low-burden disorders, and more likely to present either IVF with donor egg or surrogate motherhood as options. Social and ethical implications of this widespread acceptance of nondirective counseling are discussed.
在18个国家的1053名医学遗传学家中,677人(64%)回复了问卷,问卷涉及他们对遗传咨询七个目标的重要性、五种指导性/非指导性咨询方法的适当性以及在四种涉及指导性/非指导性咨询的情况下他们的行动选择的看法。大多数人(92%-94%)认为非指导性方法是适当的;他们对目标和方法的看法与早期对美国205名遗传咨询师的调查结果相似。在向无法进行产前诊断的疾病携带者介绍生殖选择的临床情况下,74%-85%的人即使未被询问,也会将避孕、绝育、顺其自然、供体人工授精(AID)或收养作为选择告知对方;66%的人会介绍供体卵子体外受精(IVF);46%(在美国为67%)的人会介绍代孕。对于三种涉及低负荷疾病胎儿(特纳综合征、XYY和可能的小神经管缺陷)的情况,84%-88%的人会进行非指导性咨询。对专业和个人背景变量进行的逐步逻辑回归分析表明,在跨国层面上,性别与咨询中自我报告的指导性有关,男性比女性更有可能认为指导性方法是适当的,更有可能就低负荷疾病胎儿提供建议,也更有可能将供体卵子IVF或代孕作为选择告知对方。文中讨论了这种对非指导性咨询的广泛接受所带来的社会和伦理影响。
