The Perceived Impact of Children s Risk Status for Hypertrophic Cardiomyopathy on Families: an Exploratory Study

Study Overview
=================
Brief Summary
-----------------
This study proposes to describe how children s hypertrophic cardiomyopathy (HCM) risk status affects family functioning, behaviors, and relationships. HCM is the most common inherited cardiovascular single-gene disorder. Individuals with HCM may experience shortness of breath, chest pain, palpitations, dizziness, syncope, heart failure, and arrhythmias predisposing to sudden cardiac death at any age. Notably, HCM is the most common cause of sudden cardiac death in people under 30 years of age. Genetic testing can identify at-risk individuals; however, the impact of potentially life-altering genetic information on families remains largely unexplored. Increasingly, health care providers are providing the testing in children for conditions like HCM that are life-threatening and medically manageable without the benefit of understanding the psychological consequences. The few studies that have been conducted suggest that genetic testing in children may result in changes to family relationships, parental emotional wellbeing, parenting behaviors, and child functioning in a subset of children. One synthesis of these studies suggests that children as a group show little evidence for maladjustment to risk information, but that parents are affected by the carrier status of their children. The proposed study intends to further this body of knowledge by exploring the impact of children s risk status on families with HCM. Health care providers and researchers can inform their work with HCM families by better understanding the potential impact of genetic risk as an important component of families adaptation to the life-threatening information about their children. The families targeted for this exploratory study will be purposively sampled from those that have been aware of the children s risk status or not at-risk status for HCM for at least 3 months. The cross-sectional design is composed of semi-structured interviews with a parent and, separately, with his/her 13 to 23 year-old child who is either a carrier for HCM, a non-carrier, or at 50% risk for being a carrier. The interview will target issues related to the perceived impact of the child s risk status on family functioning, parenting behaviors and relationships. Data from the parent-child dyads will be analyzed for concordance/discordance along parallel themes. The results of this study may facilitate the understanding of the perceived impact of learning children s HCM risk status, which will inform both clinical care and future research. Importantly, since predictive testing in children for adult-onset diseases is generally discouraged, very little is actually known about its impact on families. Therefore, the study of this unique subgroup of an HCM population that uses clinically indicated predictive testing in childhood offers a preliminary opportunity to learn about predictive testing of minors....
