The study sample for this research will be recruited from participants in an institutionally funded cohort study, St. Jude Life, as well as from active ACT patients that meet eligibility criteria. The young adults in St. Jude Life are a highly motivated group who were followed in the After Completion of Therapy Clinic until age 18 years and a minimum of 10 years after their treatment ended if they were older than age 11 at the end of therapy. Potentially eligible comparison group participants will be recruited from the parent, older sibling, relative or friend population who accompany the ACT patient for follow-up at SJCRH. Parents (or siblings, relatives or friends who are 18 years or older) of children in remission, both from the active follow-up cohort (within five years of last treatment) and the After Completion of Therapy (ACT) cohort will be invited to complete the same assessments that the ALL survivor participants will complete.
