The purpose of this study is to describe the interplay of adolescent girls' and young womens' self-concept, coping behaviors, and adjustment associated with knowledge of genetic risk for fragile X syndrome. We will report here findings on self-concept. Using a multi-group cross-sectional design this study focused on girls ages 14-25 years from families previously diagnosed with fragile X syndrome, who knew they were (1) carriers (n = 20; mean age 18.35 years s.d. 2.5), or (2) noncarriers (n = 18; mean age 17.78 years s.d. 2.69), or (3) at-risk to be carriers (n = 15; mean age 17.87 s.d. 3.18). The girls completed the Tennessee Self-Concept Scale (TSCS:2), a visual analog scale, and a guided interview. Total and all subscale scores on the TSCS:2 were in the normal range for all three groups. However, threats to self-concept were found in personal self (physical self, genetic identity, and parental role), social self, and family self (family genetic identity) as they specifically related to the meaning of genetic information and varied based on risk status. Our findings suggest that risk information itself is threatening and for some girls, may be as threatening as learning one is a carrier. Certainty related to genetic risk status appears to make a positive difference for some girls by allowing them the opportunity to face the challenge of their genetic risk status and to begin to consider the meaning of this information.
本研究的目的是描述青春期女孩和年轻女性的自我概念、应对行为以及与脆性X综合征遗传风险知识相关的适应之间的相互作用。我们将在此报告关于自我概念的研究结果。本研究采用多组横断面设计,重点关注来自先前被诊断患有脆性X综合征家庭的14至25岁女孩,她们知道自己是(1)携带者(n = 20;平均年龄18.35岁,标准差2.5),或(2)非携带者(n = 18;平均年龄17.78岁,标准差2.69),或(3)有成为携带者风险的人(n = 15;平均年龄17.87岁,标准差3.18)。这些女孩完成了田纳西自我概念量表(TSCS:2)、视觉模拟量表和一次指导性访谈。所有三组在TSCS:2上的总分和所有子量表得分均在正常范围内。然而,在个人自我(身体自我、遗传身份和父母角色)、社会自我和家庭自我(家庭遗传身份)方面发现了对自我概念的威胁,因为它们与遗传信息的意义具体相关,并且因风险状况而异。我们的研究结果表明,风险信息本身具有威胁性,对一些女孩来说,可能与得知自己是携带者一样具有威胁性。与遗传风险状况相关的确定性似乎对一些女孩产生了积极影响,可以让她们有机会面对遗传风险状况的挑战,并开始思考这些信息的意义。
