Adolescence is a time when individuals begin to explore and examine psychological characteristics of the self in order to discover who they really are and how they fit in the social world in which they live. It is during this time of self-exploration that adolescents at risk for Huntington's Disease often learn of their risk status and witness the debilitating symptoms of the disease in their parents. Huntington Disease (HD) is an autosomal dominant neuropsychiatric disorder characterized by mid-life onset, involuntary movements, cognitive impairment, and depression. This dissertation investigated how adolescents experience living in a family with Huntington's Disease and therefore at risk for Huntington's Disease, and how this impacts their self-understanding and self-identity. The method of inquiry was based on a phenomenological approach. In-depth interviews were conducted with each of the adolescents. The data were analyzed using Van Manen's (1980) and Cochran and Claspell's (1987) format, resulting in an extraction of three themes. These themes are: (1) Naming the Legacy: Understanding and Misunderstanding; (2) Experiencing the Legacy: Huntington's Disease in Relation to Relationships; and (3) Integrating the Legacy: At the Crossroads of Self and Future Self. The analysis emphasizes that the at-risk adolescents' exploration of self-identity and future self was an individual process influenced by the cognitive, developmental, and socio-cultural contexts of the adolescents' lives. The process of learning about Huntington's Disease occurred through intuition and practical and experiential learning. The adolescents found support outside their family through friends and adult mentors. They engaged in complicated coping strategies and demonstrated a capacity for decision-making that displayed maturity beyond what would be expected for their age group. These findings led to specific recommendations for theory, research, and clinical practice in the area of the adolescent experience of HD. The research underscores the need for healthcare professionals to re-evaluate their view of adolescent autonomy and capacity for decision-making.

The purpose of this study was to explore the association among risk behaviors, HIV/AIDS knowledge, and cognitive variables in high-risk adolescents. Subjects were 82 youth (50 males and 32 females) residing in a Midwest residential treatment facility for abused, neglected, or delinquent children and adolescents. The mean age of the adolescents was 14.6 years. Self-report measures of AIDS knowledge, invulnerability, self-efficacy, locus of control, sensation seeking, and risk involvement were administered in counterbalanced order. Data were analyzed using hierarchical multiple regression analysis to examine the relation between risk behaviors and scores on invulnerability, locus of control, self-efficacy, and sensation seeking measures once age and AIDS knowledge were controlled in the initial steps. Although age and knowledge of AIDS were related positively to the likelihood of behavioral risk taking, the combination of cognitive variables explained an additional 23% of the variance in risk behaviors and accounted for the largest proportion of shared variability. Therefore, adolescents' risk behaviors appeared to be determined by their cognitive beliefs to a greater degree than by their knowledge of the consequences of such behavior. The importance of cognitive factors in the apparent behavior choices that adolescents make suggests that educational prevention programs need to consider more than just the sharing of knowledge in addressing issues of risky behavior. Instead, the perceptions of adolescents toward sensation seeking and other cognitive characteristics also must be considered. / Department of Educational Psychology
