The proposed study aims to explore the relationships between perceived uncertainty, hope and adaptation in caregivers of children with Down Syndrome (DS). There are often uncertainties surrounding the prognosis of DS which extend into various aspects of the child s life. In addition to the possibility of chronic medical conditions associated with the syndrome, there is also uncertainty related to the level of independence and cognitive, social and behavioral functioning that the child will achieve. It is not fully understood how caregivers adapt to having a child with DS in light of the uncertainty and the particular challenges associated with this condition. While a high level of perceived uncertainty may be seen as a threat to adaptation, there is also evidence that caregivers may find benefits in uncertainty. Literature suggests that a person s level of hope influences how the perceived uncertainty is appraised and that hope is also related to the process of adaptation. There is no research that systematically explores the relationship between perceived uncertainty, hope, and adaptation. This study s conceptual framework is based on Lazarus & Folkman s Transactional Model of Stress and Coping and is also informed by Snyder s conceptualization of hope and Mishel s theory of perceived uncertainty in illness. A cross-sectional research design will quantitatively explore the relationships between perceived uncertainty, hope, and adaptation. In addition, an open-ended section will be included to qualitatively describe the focus of caregivers hope for their child and how the focus of hope relates to the degree of hope. Participants will be recruited from DS support groups, website postings, listservs, and clinic patient lists. They will have the option of completing either a paper or online version of the survey, or completing the survey by phone. The main outcome variable is psychological adaptation to being a care giver for a child with DS.
