This is an observational study to collect information by use of performance-based measures and survey questionnaires. It does not include interventions aimed at altering patient outcome. Advances in pediatric hematopoietic stem cell transplantation (SCT) have resulted in improved survival and prompted increased attention to the potential adverse late effects of this procedure. Survivors of SCT are thought to be at risk for neurocognitive deficits as a result of their exposure to a number of potentially neurotoxic agents. Prior studies done by our group and others have demonstrated generally stable cognitive function in the first 5 years following transplant, with little evidence of significant declines. However, there has been almost no research to date on the status of very long-term (\> 5 years post-transplant) survivors. In this study, we will evaluate a large sample of long-term survivors of allogeneic SCT using measures of intelligence, academic achievement, and specific cognitive functions such as attention, working memory and processing speed. We will also obtain measures of behavioral functioning and quality of life. We will examine how this group of survivors are functioning relative to normative expectations, and in comparison to community controls without a history of serious illness, matched on age, gender, race/ethnicity, and socioeconomic status. We will also examine the relationship between cognitive function and psychosocial function and quality of life in this population.

This study will involve a one-time assessment using both performance based measures as well as both self- and parent-report questionnaires. During their yearly visit to St. Jude, eligible patients who agree to participate will undergo a single neurocognitive evaluation. This evaluation will take place in the Psychology Clinic. The administration time for the assessment battery is estimated at 2.5-3.5 hours, with variability depending on the age of the patient and the speed of completion of the tasks. All measures selected for the study have well-established psychometric properties, including acceptable reliability and validity. All measures were standardized on large, representative samples of children and adults and have age-specific norms. PRIMARY OBJECTIVE: To examine and describe psychological outcomes in long-term (\> 5 years) survivors of allogeneic bone marrow or stem cell transplantation (SCT) in childhood. This will be conducted in a one-time cross-sectional assessment using both performance based measures and survey questionnaires. Comparisons will be made to established normative data on well validated standardized instruments and to control participants in the community without a history of serious illness, matched on age, gender, race/ethnicity and socioeconomic status. * To describe global cognitive and academic outcomes in this SCT cohort using measures of intelligence and academic achievement. * To examine performance in specific neuropsychologic domains, including working memory, processing speed and other executive functions. * To examine psychosocial function and quality of life among long-term SCT survivors using both self- and parent-report.
