The purpose of this National Cancer Institute (NCI) funded study is to develop and test the acceptability and usability of a web & text message based weight loss intervention for childhood acute lymphoblastic leukemia (ALL) survivors. Childhood cancer survivors ages 7 - 18 will provide feedback during focus groups on a web and text message based program that was developed.

This is a two year study to develop a predominantly web-based behavioral assessment and intervention program (PACE-CALL) that will provide individual assessment and tailoring of a behavioral intervention for adolescent children Acute Lymphoblastic Leukemia (ALL) survivors and their families. In addition, we are conducting formative research to adapt the abovementioned program to children and adolescents aged 7 - 18 who survived any cancer.

Focus Groups: Web-Based & Text Message Intervention Feedback

Two focus groups will be conducted with adolescent cancer survivors and their families, to assess the usability and acceptability of the web-based intervention, focus groups will be conducted. The two focus groups will last 2 hours with 6-8 people in each group: one focus group with youth & adolescents (age 7 - 18 who are representative of the target population to determine the appropriateness of the web-based intervention one focus group with the parents of the children in the focus group mentioned above (it will occur at the same time). All focus groups will begin with an overview of the study and description of the web-based intervention components. Focus group participants will see sample web pages and may be asked to provide feedback on some or all of the following:
