Self-concept is important to consider as a possible protective factor in response to potentially threatening information, such as learning carrier status for a genetic disorder, as well as an area of concern if information about self were to result in harm to self-concept. Importantly, how an individual defines themselves in the present as well as expectations for who they will become in the future are thought to influence behavior and responses to stressful events (
Markus and Nurius 1987;
Stein 1995).
Self-concept can be defined in many different ways, and outcomes of research on self-concept related to genetic testing have varied based on how it was defined (
McConkie-Rosell and DeVellis 2000). Self-concept can be defined using Cognitive Behavioral Theory as a multidimensional, hierarchical sense of self and self perception related to identity, feelings, thoughts, behavior, appearance, and personal characteristics (
Hattie 1992). Using this definitional approach, we have previously reported findings regarding self-concept in adolescent girls and young women who were members of families in which fragile X syndrome (FXS) had been diagnosed (
McConkie-Rosell et al. 2008). FXS is an X-linked triplet repeat disorder, which can occur due to inheritance of a full mutation (greater than 200 hypermethylated CGG repeats) (
Nolin et al. 2003). The hypermethylated full mutation results in loss of the FMR1 protein leading to a range of cognitive and behavioral abnormalities that characterize FXS (
Hagerman and Hagerman 2004). Females with the full mutation may have clinical features of FXS or can be unaffected. Females with the premutation (less than 200 repeats is not hypermethylated) are at increased risk for the FMR1 disorders of Fragile X-Associated Primary Ovarian Insufficiency (FXPOI) and Fragile X-Associated Tremor and Ataxia (FXTAS) (
McConkie-Rosell et al. 2005). Carrier females may have either the full mutation or a premutation. We reported findings related to self-concept as it was measured by the Tennessee Self-Concept Scale (
Fitts and Warren 1996), a self-rated visual analog scale, and descriptions from interviews with adolescent girls and young women in three groups with knowledge of their genetic risk status (carriers, non-carriers, and individuals who knew only that they could be a carrier for FXS, referred to hereafter as “at risk”) (
McConkie-Rosell et al. 2008). We found that although the mean scores on the Tennessee Self-Concept Scale were within the normal range for all three groups, differences in feelings about self were observed on the visual analog scale and in the interviews. On the visual analog scale we found that adolescent girls and young women who knew only that they “could be” a carrier for FXS reported diminished feelings about self related to their genetic risk status. These adolescent girls and young women also reported a significant negative effect on their relationships with friends compared to those who knew they were either carriers or non-carriers.
Using Identity Theory, self-concept can also be defined through the different roles an individual adopts. There are three assumptions of Identity Theory: 1) self-concept is developed from multiple internalized roles that have a shared personal and societal meaning, 2) there are specific behaviors or activities that are required to enact the role, and 3) the roles have a hierarchical structure based on the salience of a particular role to the individual and to society (
Howard 1991;
Stryker 1991). Salience includes the value, commitment to, and level of importance of a role to the individual, and the more salient a role the greater the effect of that role on the development of the individual’s self-concept (
Thoits 1991). Some roles are chosen by the individual (e.g., athlete) while others (e.g., sibling) are not. Some roles are also considered by the society in which the individual lives as a normal and attainable role (e.g., health professional) while others are not as commonly enacted (e.g., president). Identity Theory then predicts that a barrier to enacting a valued normative role may have an effect on a developing self-concept (
Thoits 1991).
Based on these concepts, we have proposed that a possible mechanism by which self-concept might be altered based on genetic information is through a perceived barrier to the enactment of the parental role (
McConkie-Rosell and DeVellis 2000). Genetic knowledge may challenge a “wished for” parental role several ways. First, learning carrier status may alter how a person defines him/herself in relation to reproductive expectations. For adolescents and young adults who know they are carriers of a genetic disorder, this changed perspective may lead to feelings of reduced desirability for marriage. The definition of the parental role and how the role is enacted may also be altered based on the possibility of parenting an affected child.
In a study of adult women who each had a 50% chance of being a carrier for FXS, we found some evidence that change in perception of the parental role occurs as part of learning about genetic risk for this disorder. These women expressed concern about what "being a carrier" meant for future reproduction for their children or grandchildren, or, if their families were not complete, for themselves (
McConkie-Rosell et al. 2000).
Findings from the adult research may have limited applicability to adolescents because of differences in the stability of self-concept in these age groups. Unlike a mature adult whose self-concept is generally considered stable, an adolescent's self-concept is developing and is affected by tasks and challenges (
Baumeister 1998). Adolescents are also trying on new roles and identities, developing their sexuality, and thinking about the future, while simultaneously seeking approval from peers and family and asserting their independence (
Balk 1994;
Erikson 1963). There is growing evidence that personal identity is a developmental continuum which includes exploration, choices, and commitment to those choices (
Meeus 2011).
Because conceptualization of future roles may begin prior to their enactment (
Markus and Nurius 1987), an adolescent who knows either she is a carrier or is at-risk to be a carrier may not explore a future parental role identity because of a perceived barrier. For those adolescents for whom this identity is already developed, a perceived barrier to the goal of becoming a parent may result in distress. Additionally, a barrier that is perceived to be insurmountable may result in identity foreclosure. Identity foreclosure occurs when the individual no longer imagines enacting a future role (
Balk 1994;
Markus and Nurius 1987) or abandons efforts to achieve that specific goal (
Brandtstadter and Rothermund 2002;
Rothermund 2011). Because of these concerns we specifically explored concepts related to the importance of becoming a mother and plans for the enactment of the parental role as part of the adolescent fragile X study. We report herein our findings regarding parental role.
